Merge tag 'xfs-4.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull more xfs updates from Darrick Wong:
"As promised, here's a (much smaller) second pull request for the
second week of the merge cycle. This time around we have a couple
patches shutting off unsupported fs configurations, and a couple of
cleanups.
Last, we turn off EXPERIMENTAL for the reverse mapping btree, since
the primary downstream user of that information (online fsck) is now
upstream and I haven't seen any major failures in a few kernel
releases.
Summary:
- Print scrub build status in the xfs build info.
- Explicitly call out the remaining two scenarios where we don't
support reflink and never have.
- Remove EXPERIMENTAL tag from reverse mapping btree!"
* tag 'xfs-4.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
xfs: remove experimental tag for reverse mapping
xfs: don't allow reflink + realtime filesystems
xfs: don't allow DAX on reflink filesystems
xfs: add scrub to XFS_BUILD_OPTIONS
xfs: fix u32 type usage in sb validation function

+
+ The DbC debug device shares a root port with xHCI host.
+ When the DbC is enabled, the root port will be assigned
+ to the Debug Capability. Otherwise, it will be assigned
+ to xHCI.
+
+ Writing "enable" to this attribute will enable the DbC
+ functionality and the shared root port will be assigned
+ to the DbC device. Writing "disable" to this attribute
+ will disable the DbC functionality and the shared root
+ port will roll back to the xHCI.

+ can be one of the following states: disabled, enabled,
+ initialized, connected, configured and stalled.

+========================================================
+OpenCAPI (Open Coherent Accelerator Processor Interface)
+========================================================
+
+OpenCAPI is an interface between processors and accelerators. It aims
+at being low-latency and high-bandwidth. The specification is
+developed by the `OpenCAPI Consortium <http://opencapi.org/>`_.
+
+It allows an accelerator (which could be a FPGA, ASICs, ...) to access
+the host memory coherently, using virtual addresses. An OpenCAPI
+device can also host its own memory, that can be accessed from the
+host.
+
+OpenCAPI is known in linux as 'ocxl', as the open, processor-agnostic
+evolution of 'cxl' (the driver for the IBM CAPI interface for
+powerpc), which was named that way to avoid confusion with the ISDN
+CAPI subsystem.
+
+
+High-level view
+===============
+
+OpenCAPI defines a Data Link Layer (DL) and Transaction Layer (TL), to
+be implemented on top of a physical link. Any processor or device
+implementing the DL and TL can start sharing memory.
+
+::
+
+ +-----------+ +-------------+
+ | | | |
+ | | | Accelerated |
+ | Processor | | Function |
+ | | +--------+ | Unit | +--------+
+ | |--| Memory | | (AFU) |--| Memory |
+ | | +--------+ | | +--------+
+ +-----------+ +-------------+
+ | |
+ +-----------+ +-------------+
+ | TL | | TLX |
+ +-----------+ +-------------+
+ | |
+ +-----------+ +-------------+
+ | DL | | DLX |
+ +-----------+ +-------------+
+ | |
+ | PHY |
+ +---------------------------------------+
+
+
+
+Device discovery
+================
+
+OpenCAPI relies on a PCI-like configuration space, implemented on the
+device. So the host can discover AFUs by querying the config space.
+
+OpenCAPI devices in Linux are treated like PCI devices (with a few
+caveats). The firmware is expected to abstract the hardware as if it
+was a PCI link. A lot of the existing PCI infrastructure is reused:
+devices are scanned and BARs are assigned during the standard PCI
+enumeration. Commands like 'lspci' can therefore be used to see what
+devices are available.
+
+The configuration space defines the AFU(s) that can be found on the
+physical adapter, such as its name, how many memory contexts it can
+work with, the size of its MMIO areas, ...
+
+
+
+MMIO
+====
+
+OpenCAPI defines two MMIO areas for each AFU:
+
+* the global MMIO area, with registers pertinent to the whole AFU.
+* a per-process MMIO area, which has a fixed size for each context.
+
+
+
+AFU interrupts
+==============
+
+OpenCAPI includes the possibility for an AFU to send an interrupt to a
+host process. It is done through a 'intrp_req' defined in the
+Transaction Layer, specifying a 64-bit object handle which defines the
+interrupt.
+
+The driver allows a process to allocate an interrupt and obtain its
+64-bit object handle, that can be passed to the AFU.
+
+
+
+char devices
+============
+
+The driver creates one char device per AFU found on the physical
+device. A physical device may have multiple functions and each
+function can have multiple AFUs. At the time of this writing though,
+it has only been tested with devices exporting only one AFU.
+
+Char devices can be found in /dev/ocxl/ and are named as:
+/dev/ocxl/<AFU name>.<location>.<index>
+
+where <AFU name> is a max 20-character long name, as found in the
+config space of the AFU.
+<location> is added by the driver and can help distinguish devices
+when a system has more than one instance of the same OpenCAPI device.
+<index> is also to help distinguish AFUs in the unlikely case where a
+device carries multiple copies of the same AFU.
+
+
+
+Sysfs class
+===========
+
+An ocxl class is added for the devices representing the AFUs. See
+/sys/class/ocxl. The layout is described in
+Documentation/ABI/testing/sysfs-class-ocxl
+
+
+
+User API
+========
+
+open
+----
+
+Based on the AFU definition found in the config space, an AFU may
+support working with more than one memory context, in which case the
+associated char device may be opened multiple times by different
+processes.
+
+
+ioctl
+-----
+
+OCXL_IOCTL_ATTACH:
+
+ Attach the memory context of the calling process to the AFU so that
+ the AFU can access its memory.
+
+OCXL_IOCTL_IRQ_ALLOC:
+
+ Allocate an AFU interrupt and return an identifier.
+
+OCXL_IOCTL_IRQ_FREE:
+
+ Free a previously allocated AFU interrupt.
+
+OCXL_IOCTL_IRQ_SET_FD:
+
+ Associate an event fd to an AFU interrupt so that the user process
+ can be notified when the AFU sends an interrupt.
+
+
+mmap
+----
+
+A process can mmap the per-process MMIO area for interactions with the
+AFU.

+This document provides information for the BPF subsystem about various
+workflows related to reporting bugs, submitting patches, and queueing
+patches for stable kernels.
+
+For general information about submitting patches, please refer to
+Documentation/process/. This document only describes additional specifics
+related to BPF.
+
+Reporting bugs:
+---------------
+
+Q: How do I report bugs for BPF kernel code?
+
+A: Since all BPF kernel development as well as bpftool and iproute2 BPF
+ loader development happens through the netdev kernel mailing list,
+ please report any found issues around BPF to the following mailing
+ list:
+
+ netdev@vger.kernel.org
+
+ This may also include issues related to XDP, BPF tracing, etc.
+
+ Given netdev has a high volume of traffic, please also add the BPF
+ maintainers to Cc (from kernel MAINTAINERS file):
+
+ Alexei Starovoitov <ast@kernel.org>
+ Daniel Borkmann <daniel@iogearbox.net>
+
+ In case a buggy commit has already been identified, make sure to keep
+ the actual commit authors in Cc as well for the report. They can
+ typically be identified through the kernel's git tree.
+
+ Please do *not* report BPF issues to bugzilla.kernel.org since it
+ is a guarantee that the reported issue will be overlooked.
+
+Submitting patches:
+-------------------
+
+Q: To which mailing list do I need to submit my BPF patches?
+
+A: Please submit your BPF patches to the netdev kernel mailing list:
+
+ netdev@vger.kernel.org
+
+ Historically, BPF came out of networking and has always been maintained
+ by the kernel networking community. Although these days BPF touches
+ many other subsystems as well, the patches are still routed mainly
+ through the networking community.
+
+ In case your patch has changes in various different subsystems (e.g.
+ tracing, security, etc), make sure to Cc the related kernel mailing
+ lists and maintainers from there as well, so they are able to review
+ the changes and provide their Acked-by's to the patches.
+
+Q: Where can I find patches currently under discussion for BPF subsystem?
+
+A: All patches that are Cc'ed to netdev are queued for review under netdev
+ patchwork project:
+
+ http://patchwork.ozlabs.org/project/netdev/list/
+
+ Those patches which target BPF, are assigned to a 'bpf' delegate for
+ further processing from BPF maintainers. The current queue with
+ patches under review can be found at:
+
+ https://patchwork.ozlabs.org/project/netdev/list/?delegate=77147
+
+ Once the patches have been reviewed by the BPF community as a whole
+ and approved by the BPF maintainers, their status in patchwork will be
+ changed to 'Accepted' and the submitter will be notified by mail. This
+ means that the patches look good from a BPF perspective and have been
+ applied to one of the two BPF kernel trees.
+
+ In case feedback from the community requires a respin of the patches,
+ their status in patchwork will be set to 'Changes Requested', and purged
+ from the current review queue. Likewise for cases where patches would
+ get rejected or are not applicable to the BPF trees (but assigned to
+ the 'bpf' delegate).
+
+Q: How do the changes make their way into Linux?
+
+A: There are two BPF kernel trees (git repositories). Once patches have
+ been accepted by the BPF maintainers, they will be applied to one
+ of the two BPF trees:
+
+ https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git/
+ https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git/
+
+ The bpf tree itself is for fixes only, whereas bpf-next for features,
+ cleanups or other kind of improvements ("next-like" content). This is
+ analogous to net and net-next trees for networking. Both bpf and
+ bpf-next will only have a master branch in order to simplify against
+ which branch patches should get rebased to.
+
+ Accumulated BPF patches in the bpf tree will regularly get pulled
+ into the net kernel tree. Likewise, accumulated BPF patches accepted
+ into the bpf-next tree will make their way into net-next tree. net and
+ net-next are both run by David S. Miller. From there, they will go
+ into the kernel mainline tree run by Linus Torvalds. To read up on the
+ process of net and net-next being merged into the mainline tree, see
+ the netdev FAQ under:
+
+ Documentation/networking/netdev-FAQ.txt
+
+ Occasionally, to prevent merge conflicts, we might send pull requests
+ to other trees (e.g. tracing) with a small subset of the patches, but
+ net and net-next are always the main trees targeted for integration.
+
+ The pull requests will contain a high-level summary of the accumulated
+ patches and can be searched on netdev kernel mailing list through the
+ following subject lines (yyyy-mm-dd is the date of the pull request):
+
+ pull-request: bpf yyyy-mm-dd
+ pull-request: bpf-next yyyy-mm-dd
+
+Q: How do I indicate which tree (bpf vs. bpf-next) my patch should be
+ applied to?
+
+A: The process is the very same as described in the netdev FAQ, so
+ please read up on it. The subject line must indicate whether the
+ patch is a fix or rather "next-like" content in order to let the
+ maintainers know whether it is targeted at bpf or bpf-next.
+
+ For fixes eventually landing in bpf -> net tree, the subject must
+ look like:
+
+ git format-patch --subject-prefix='PATCH bpf' start..finish
+
+ For features/improvements/etc that should eventually land in
+ bpf-next -> net-next, the subject must look like:
+
+ git format-patch --subject-prefix='PATCH bpf-next' start..finish
+
+ If unsure whether the patch or patch series should go into bpf
+ or net directly, or bpf-next or net-next directly, it is not a
+ problem either if the subject line says net or net-next as target.
+ It is eventually up to the maintainers to do the delegation of
+ the patches.
+
+ If it is clear that patches should go into bpf or bpf-next tree,
+ please make sure to rebase the patches against those trees in
+ order to reduce potential conflicts.
+
+ In case the patch or patch series has to be reworked and sent out
+ again in a second or later revision, it is also required to add a
+ version number (v2, v3, ...) into the subject prefix:
+
+ git format-patch --subject-prefix='PATCH net-next v2' start..finish
+
+ When changes have been requested to the patch series, always send the
+ whole patch series again with the feedback incorporated (never send
+ individual diffs on top of the old series).
+
+Q: What does it mean when a patch gets applied to bpf or bpf-next tree?
+
+A: It means that the patch looks good for mainline inclusion from
+ a BPF point of view.
+
+ Be aware that this is not a final verdict that the patch will
+ automatically get accepted into net or net-next trees eventually:
+
+ On the netdev kernel mailing list reviews can come in at any point
+ in time. If discussions around a patch conclude that they cannot
+ get included as-is, we will either apply a follow-up fix or drop
+ them from the trees entirely. Therefore, we also reserve to rebase
+ the trees when deemed necessary. After all, the purpose of the tree
+ is to i) accumulate and stage BPF patches for integration into trees
+ like net and net-next, and ii) run extensive BPF test suite and
+ workloads on the patches before they make their way any further.
+
+ Once the BPF pull request was accepted by David S. Miller, then
+ the patches end up in net or net-next tree, respectively, and
+ make their way from there further into mainline. Again, see the
+ netdev FAQ for additional information e.g. on how often they are
+ merged to mainline.
+
+Q: How long do I need to wait for feedback on my BPF patches?
+
+A: We try to keep the latency low. The usual time to feedback will
+ be around 2 or 3 business days. It may vary depending on the
+ complexity of changes and current patch load.
+
+Q: How often do you send pull requests to major kernel trees like
+ net or net-next?
+
+A: Pull requests will be sent out rather often in order to not
+ accumulate too many patches in bpf or bpf-next.
+
+ As a rule of thumb, expect pull requests for each tree regularly
+ at the end of the week. In some cases pull requests could additionally
+ come also in the middle of the week depending on the current patch
+ load or urgency.
+
+Q: Are patches applied to bpf-next when the merge window is open?
+
+A: For the time when the merge window is open, bpf-next will not be
+ processed. This is roughly analogous to net-next patch processing,
+ so feel free to read up on the netdev FAQ about further details.
+
+ During those two weeks of merge window, we might ask you to resend
+ your patch series once bpf-next is open again. Once Linus released
+ a v*-rc1 after the merge window, we continue processing of bpf-next.
+
+ For non-subscribers to kernel mailing lists, there is also a status
+ page run by David S. Miller on net-next that provides guidance:
+
+ http://vger.kernel.org/~davem/net-next.html
+
+Q: I made a BPF verifier change, do I need to add test cases for
+ BPF kernel selftests?
+
+A: If the patch has changes to the behavior of the verifier, then yes,
+ it is absolutely necessary to add test cases to the BPF kernel
+ selftests suite. If they are not present and we think they are
+ needed, then we might ask for them before accepting any changes.
+
+ In particular, test_verifier.c is tracking a high number of BPF test
+ cases, including a lot of corner cases that LLVM BPF back end may
+ generate out of the restricted C code. Thus, adding test cases is
+ absolutely crucial to make sure future changes do not accidentally
+ affect prior use-cases. Thus, treat those test cases as: verifier
+ behavior that is not tracked in test_verifier.c could potentially
+ be subject to change.
+
+Q: When should I add code to samples/bpf/ and when to BPF kernel
+ selftests?
+
+A: In general, we prefer additions to BPF kernel selftests rather than
+ samples/bpf/. The rationale is very simple: kernel selftests are
+ regularly run by various bots to test for kernel regressions.
+
+ The more test cases we add to BPF selftests, the better the coverage
+ and the less likely it is that those could accidentally break. It is
+ not that BPF kernel selftests cannot demo how a specific feature can
+ be used.
+
+ That said, samples/bpf/ may be a good place for people to get started,
+ so it might be advisable that simple demos of features could go into
+ samples/bpf/, but advanced functional and corner-case testing rather
+ into kernel selftests.
+
+ If your sample looks like a test case, then go for BPF kernel selftests
+ instead!
+
+Q: When should I add code to the bpftool?
+
+A: The main purpose of bpftool (under tools/bpf/bpftool/) is to provide
+ a central user space tool for debugging and introspection of BPF programs
+ and maps that are active in the kernel. If UAPI changes related to BPF
+ enable for dumping additional information of programs or maps, then
+ bpftool should be extended as well to support dumping them.
+
+Q: When should I add code to iproute2's BPF loader?
+
+A: For UAPI changes related to the XDP or tc layer (e.g. cls_bpf), the
+ convention is that those control-path related changes are added to
+ iproute2's BPF loader as well from user space side. This is not only
+ useful to have UAPI changes properly designed to be usable, but also
+ to make those changes available to a wider user base of major
+ downstream distributions.
+
+Q: Do you accept patches as well for iproute2's BPF loader?
+
+A: Patches for the iproute2's BPF loader have to be sent to:
+
+ netdev@vger.kernel.org
+
+ While those patches are not processed by the BPF kernel maintainers,
+ please keep them in Cc as well, so they can be reviewed.
+
+ The official git repository for iproute2 is run by Stephen Hemminger
+ and can be found at:
+
+ https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/
+
+ The patches need to have a subject prefix of '[PATCH iproute2 master]'
+ or '[PATCH iproute2 net-next]'. 'master' or 'net-next' describes the
+ target branch where the patch should be applied to. Meaning, if kernel
+ changes went into the net-next kernel tree, then the related iproute2
+ changes need to go into the iproute2 net-next branch, otherwise they
+ can be targeted at master branch. The iproute2 net-next branch will get
+ merged into the master branch after the current iproute2 version from
+ master has been released.
+
+ Like BPF, the patches end up in patchwork under the netdev project and
+ are delegated to 'shemminger' for further processing:
+
+ http://patchwork.ozlabs.org/project/netdev/list/?delegate=389
+
+Q: What is the minimum requirement before I submit my BPF patches?
+
+A: When submitting patches, always take the time and properly test your
+ patches *prior* to submission. Never rush them! If maintainers find
+ that your patches have not been properly tested, it is a good way to
+ get them grumpy. Testing patch submissions is a hard requirement!
+
+ Note, fixes that go to bpf tree *must* have a Fixes: tag included. The
+ same applies to fixes that target bpf-next, where the affected commit
+ is in net-next (or in some cases bpf-next). The Fixes: tag is crucial
+ in order to identify follow-up commits and tremendously helps for people
+ having to do backporting, so it is a must have!
+
+ We also don't accept patches with an empty commit message. Take your
+ time and properly write up a high quality commit message, it is
+ essential!
+
+ Think about it this way: other developers looking at your code a month
+ from now need to understand *why* a certain change has been done that
+ way, and whether there have been flaws in the analysis or assumptions
+ that the original author did. Thus providing a proper rationale and
+ describing the use-case for the changes is a must.
+
+ Patch submissions with >1 patch must have a cover letter which includes
+ a high level description of the series. This high level summary will
+ then be placed into the merge commit by the BPF maintainers such that
+ it is also accessible from the git log for future reference.
+
+Q: What do I need to consider when adding a new instruction or feature
+ that would require BPF JIT and/or LLVM integration as well?
+
+A: We try hard to keep all BPF JITs up to date such that the same user
+ experience can be guaranteed when running BPF programs on different
+ architectures without having the program punt to the less efficient
+ interpreter in case the in-kernel BPF JIT is enabled.
+
+ If you are unable to implement or test the required JIT changes for
+ certain architectures, please work together with the related BPF JIT
+ developers in order to get the feature implemented in a timely manner.
+ Please refer to the git log (arch/*/net/) to locate the necessary
+ people for helping out.
+
+ Also always make sure to add BPF test cases (e.g. test_bpf.c and
+ test_verifier.c) for new instructions, so that they can receive
+ broad test coverage and help run-time testing the various BPF JITs.
+
+ In case of new BPF instructions, once the changes have been accepted
+ into the Linux kernel, please implement support into LLVM's BPF back
+ end. See LLVM section below for further information.
+
+Stable submission:
+------------------
+
+Q: I need a specific BPF commit in stable kernels. What should I do?
+
+A: In case you need a specific fix in stable kernels, first check whether
+ the commit has already been applied in the related linux-*.y branches:
+
+ https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/
+
+ If not the case, then drop an email to the BPF maintainers with the
+ netdev kernel mailing list in Cc and ask for the fix to be queued up:
+
+ netdev@vger.kernel.org
+
+ The process in general is the same as on netdev itself, see also the
+ netdev FAQ document.
+
+Q: Do you also backport to kernels not currently maintained as stable?
+
+A: No. If you need a specific BPF commit in kernels that are currently not
+ maintained by the stable maintainers, then you are on your own.
+
+ The current stable and longterm stable kernels are all listed here:
+
+ https://www.kernel.org/
+
+Q: The BPF patch I am about to submit needs to go to stable as well. What
+ should I do?
+
+A: The same rules apply as with netdev patch submissions in general, see
+ netdev FAQ under:
+
+ Documentation/networking/netdev-FAQ.txt
+
+ Never add "Cc: stable@vger.kernel.org" to the patch description, but
+ ask the BPF maintainers to queue the patches instead. This can be done
+ with a note, for example, under the "---" part of the patch which does
+ not go into the git log. Alternatively, this can be done as a simple
+ request by mail instead.
+
+Q: Where do I find currently queued BPF patches that will be submitted
+ to stable?
+
+A: Once patches that fix critical bugs got applied into the bpf tree, they
+ are queued up for stable submission under:
+
+ http://patchwork.ozlabs.org/bundle/bpf/stable/?state=*
+
+ They will be on hold there at minimum until the related commit made its
+ way into the mainline kernel tree.
+
+ After having been under broader exposure, the queued patches will be
+ submitted by the BPF maintainers to the stable maintainers.
+
+Testing patches:
+----------------
+
+Q: Which BPF kernel selftests version should I run my kernel against?
+
+A: If you run a kernel xyz, then always run the BPF kernel selftests from
+ that kernel xyz as well. Do not expect that the BPF selftest from the
+ latest mainline tree will pass all the time.
+
+ In particular, test_bpf.c and test_verifier.c have a large number of
+ test cases and are constantly updated with new BPF test sequences, or
+ existing ones are adapted to verifier changes e.g. due to verifier
+ becoming smarter and being able to better track certain things.
+
+LLVM:
+-----
+
+Q: Where do I find LLVM with BPF support?
+
+A: The BPF back end for LLVM is upstream in LLVM since version 3.7.1.
+
+ All major distributions these days ship LLVM with BPF back end enabled,
+ so for the majority of use-cases it is not required to compile LLVM by
+ hand anymore, just install the distribution provided package.
+
+ LLVM's static compiler lists the supported targets through 'llc --version',
+ make sure BPF targets are listed. Example:
+
+ $ llc --version
+ LLVM (http://llvm.org/):
+ LLVM version 6.0.0svn
+ Optimized build.
+ Default target: x86_64-unknown-linux-gnu
+ Host CPU: skylake
+
+ Registered Targets:
+ bpf - BPF (host endian)
+ bpfeb - BPF (big endian)
+ bpfel - BPF (little endian)
+ x86 - 32-bit X86: Pentium-Pro and above
+ x86-64 - 64-bit X86: EM64T and AMD64
+
+ For developers in order to utilize the latest features added to LLVM's
+ BPF back end, it is advisable to run the latest LLVM releases. Support
+ for new BPF kernel features such as additions to the BPF instruction
+ set are often developed together.
+
+ All LLVM releases can be found at: http://releases.llvm.org/
+
+Q: Got it, so how do I build LLVM manually anyway?
+
+A: You need cmake and gcc-c++ as build requisites for LLVM. Once you have
+ that set up, proceed with building the latest LLVM and clang version
+ from the git repositories:
+
+ $ git clone http://llvm.org/git/llvm.git
+ $ cd llvm/tools
+ $ git clone --depth 1 http://llvm.org/git/clang.git
+ $ cd ..; mkdir build; cd build
+ $ cmake .. -DLLVM_TARGETS_TO_BUILD="BPF;X86" \
+ -DBUILD_SHARED_LIBS=OFF \
+ -DCMAKE_BUILD_TYPE=Release \
+ -DLLVM_BUILD_RUNTIME=OFF
+ $ make -j $(getconf _NPROCESSORS_ONLN)
+
+ The built binaries can then be found in the build/bin/ directory, where
+ you can point the PATH variable to.
+
+Q: Should I notify BPF kernel maintainers about issues in LLVM's BPF code
+ generation back end or about LLVM generated code that the verifier
+ refuses to accept?
+
+A: Yes, please do! LLVM's BPF back end is a key piece of the whole BPF
+ infrastructure and it ties deeply into verification of programs from the
+ kernel side. Therefore, any issues on either side need to be investigated
+ and fixed whenever necessary.
+
+ Therefore, please make sure to bring them up at netdev kernel mailing
+ list and Cc BPF maintainers for LLVM and kernel bits:
+
+ Yonghong Song <yhs@fb.com>
+ Alexei Starovoitov <ast@kernel.org>
+ Daniel Borkmann <daniel@iogearbox.net>
+
+ LLVM also has an issue tracker where BPF related bugs can be found:
+
+ https://bugs.llvm.org/buglist.cgi?quicksearch=bpf
+
+ However, it is better to reach out through mailing lists with having
+ maintainers in Cc.
+
+Q: I have added a new BPF instruction to the kernel, how can I integrate
+ it into LLVM?
+
+A: LLVM has a -mcpu selector for the BPF back end in order to allow the
+ selection of BPF instruction set extensions. By default the 'generic'
+ processor target is used, which is the base instruction set (v1) of BPF.
+
+ LLVM has an option to select -mcpu=probe where it will probe the host
+ kernel for supported BPF instruction set extensions and selects the
+ optimal set automatically.
+
+ For cross-compilation, a specific version can be select manually as well.
+
+ $ llc -march bpf -mcpu=help
+ Available CPUs for this target:
+
+ generic - Select the generic processor.
+ probe - Select the probe processor.
+ v1 - Select the v1 processor.
+ v2 - Select the v2 processor.
+ [...]
+
+ Newly added BPF instructions to the Linux kernel need to follow the same
+ scheme, bump the instruction set version and implement probing for the
+ extensions such that -mcpu=probe users can benefit from the optimization
+ transparently when upgrading their kernels.
+
+ If you are unable to implement support for the newly added BPF instruction
+ please reach out to BPF developers for help.
+
+ By the way, the BPF kernel selftests run with -mcpu=probe for better
+ test coverage.
+
+Happy BPF hacking!

+=====================
+The errseq_t datatype
+=====================
+
+An errseq_t is a way of recording errors in one place, and allowing any
+number of "subscribers" to tell whether it has changed since a previous
+point where it was sampled.
+
+The initial use case for this is tracking errors for file
+synchronization syscalls (fsync, fdatasync, msync and sync_file_range),
+but it may be usable in other situations.
+
+It's implemented as an unsigned 32-bit value. The low order bits are
+designated to hold an error code (between 1 and MAX_ERRNO). The upper bits
+are used as a counter. This is done with atomics instead of locking so that
+these functions can be called from any context.
+
+Note that there is a risk of collisions if new errors are being recorded
+frequently, since we have so few bits to use as a counter.
+
+To mitigate this, the bit between the error value and counter is used as
+a flag to tell whether the value has been sampled since a new value was
+recorded. That allows us to avoid bumping the counter if no one has
+sampled it since the last time an error was recorded.
+
+Thus we end up with a value that looks something like this:
+
++--------------------------------------+----+------------------------+
+| 31..13 | 12 | 11..0 |
++--------------------------------------+----+------------------------+
+| counter | SF | errno |
++--------------------------------------+----+------------------------+
+
+The general idea is for "watchers" to sample an errseq_t value and keep
+it as a running cursor. That value can later be used to tell whether
+any new errors have occurred since that sampling was done, and atomically
+record the state at the time that it was checked. This allows us to
+record errors in one place, and then have a number of "watchers" that
+can tell whether the value has changed since they last checked it.
+
+A new errseq_t should always be zeroed out. An errseq_t value of all zeroes
+is the special (but common) case where there has never been an error. An all
+zero value thus serves as the "epoch" if one wishes to know whether there
+has ever been an error set since it was first initialized.
+
+API usage
+=========
+
+Let me tell you a story about a worker drone. Now, he's a good worker
+overall, but the company is a little...management heavy. He has to
+report to 77 supervisors today, and tomorrow the "big boss" is coming in
+from out of town and he's sure to test the poor fellow too.
+
+They're all handing him work to do -- so much he can't keep track of who
+handed him what, but that's not really a big problem. The supervisors
+just want to know when he's finished all of the work they've handed him so
+far and whether he made any mistakes since they last asked.
+
+He might have made the mistake on work they didn't actually hand him,
+but he can't keep track of things at that level of detail, all he can
+remember is the most recent mistake that he made.
+
+Here's our worker_drone representation::
+
+ struct worker_drone {
+ errseq_t wd_err; /* for recording errors */
+ };
+
+Every day, the worker_drone starts out with a blank slate::
+
+ struct worker_drone wd;
+
+ wd.wd_err = (errseq_t)0;
+
+The supervisors come in and get an initial read for the day. They
+don't care about anything that happened before their watch begins::
+
+ struct supervisor {
+ errseq_t s_wd_err; /* private "cursor" for wd_err */
+ spinlock_t s_wd_err_lock; /* protects s_wd_err */
+ }
+
+ struct supervisor su;
+
+ su.s_wd_err = errseq_sample(&wd.wd_err);
+ spin_lock_init(&su.s_wd_err_lock);
+
+Now they start handing him tasks to do. Every few minutes they ask him to
+finish up all of the work they've handed him so far. Then they ask him
+whether he made any mistakes on any of it::
+
+ spin_lock(&su.su_wd_err_lock);
+ err = errseq_check_and_advance(&wd.wd_err, &su.s_wd_err);
+ spin_unlock(&su.su_wd_err_lock);
+
+Up to this point, that just keeps returning 0.
+
+Now, the owners of this company are quite miserly and have given him
+substandard equipment with which to do his job. Occasionally it
+glitches and he makes a mistake. He sighs a heavy sigh, and marks it
+down::
+
+ errseq_set(&wd.wd_err, -EIO);
+
+...and then gets back to work. The supervisors eventually poll again
+and they each get the error when they next check. Subsequent calls will
+return 0, until another error is recorded, at which point it's reported
+to each of them once.
+
+Note that the supervisors can't tell how many mistakes he made, only
+whether one was made since they last checked, and the latest value
+recorded.
+
+Occasionally the big boss comes in for a spot check and asks the worker
+to do a one-off job for him. He's not really watching the worker
+full-time like the supervisors, but he does need to know whether a
+mistake occurred while his job was processing.
+
+He can just sample the current errseq_t in the worker, and then use that
+to tell whether an error has occurred later::
+
+ errseq_t since = errseq_sample(&wd.wd_err);
+ /* submit some work and wait for it to complete */
+ err = errseq_check(&wd.wd_err, since);
+
+Since he's just going to discard "since" after that point, he doesn't
+need to advance it here. He also doesn't need any locking since it's
+not usable by anyone else.
+
+Serializing errseq_t cursor updates
+===================================
+
+Note that the errseq_t API does not protect the errseq_t cursor during a
+check_and_advance_operation. Only the canonical error code is handled
+atomically. In a situation where more than one task might be using the
+same errseq_t cursor at the same time, it's important to serialize
+updates to that cursor.
+
+If that's not done, then it's possible for the cursor to go backward
+in which case the same error could be reported more than once.
+
+Because of this, it's often advantageous to first do an errseq_check to
+see if anything has changed, and only later do an
+errseq_check_and_advance after taking the lock. e.g.::
+
+ if (errseq_check(&wd.wd_err, READ_ONCE(su.s_wd_err)) {
+ /* su.s_wd_err is protected by s_wd_err_lock */
+ spin_lock(&su.s_wd_err_lock);
+ err = errseq_check_and_advance(&wd.wd_err, &su.s_wd_err);
+ spin_unlock(&su.s_wd_err_lock);
+ }
+
+That avoids the spinlock in the common case where nothing has changed
+since the last time it was checked.

+=========================================
+How to get printk format specifiers right
+=========================================
+
+:Author: Randy Dunlap <rdunlap@infradead.org>
+:Author: Andrew Murray <amurray@mpc-data.co.uk>
+
+
+Integer types
+=============
+
+::
+
+ If variable is of Type, use printk format specifier:
+ ------------------------------------------------------------
+ int %d or %x
+ unsigned int %u or %x
+ long %ld or %lx
+ unsigned long %lu or %lx
+ long long %lld or %llx
+ unsigned long long %llu or %llx
+ size_t %zu or %zx
+ ssize_t %zd or %zx
+ s32 %d or %x
+ u32 %u or %x
+ s64 %lld or %llx
+ u64 %llu or %llx
+
+
+If <type> is dependent on a config option for its size (e.g., sector_t,
+blkcnt_t) or is architecture-dependent for its size (e.g., tcflag_t), use a
+format specifier of its largest possible type and explicitly cast to it.
+
+Example::
+
+ printk("test: sector number/total blocks: %llu/%llu\n",
+ (unsigned long long)sector, (unsigned long long)blockcount);
+
+Reminder: sizeof() returns type size_t.
+
+The kernel's printf does not support %n. Floating point formats (%e, %f,
+%g, %a) are also not recognized, for obvious reasons. Use of any
+unsupported specifier or length qualifier results in a WARN and early
+return from vsnprintf().
+
+Pointer types
+=============
+
+A raw pointer value may be printed with %p which will hash the address
+before printing. The kernel also supports extended specifiers for printing
+pointers of different types.
+
+Plain Pointers
+--------------
+
+::
+
+ %p abcdef12 or 00000000abcdef12
+
+Pointers printed without a specifier extension (i.e unadorned %p) are
+hashed to prevent leaking information about the kernel memory layout. This
+has the added benefit of providing a unique identifier. On 64-bit machines
+the first 32 bits are zeroed. If you *really* want the address see %px
+below.
+
+Symbols/Function Pointers
+-------------------------
+
+::
+
+ %pS versatile_init+0x0/0x110
+ %ps versatile_init
+ %pF versatile_init+0x0/0x110
+ %pf versatile_init
+ %pSR versatile_init+0x9/0x110
+ (with __builtin_extract_return_addr() translation)
+ %pB prev_fn_of_versatile_init+0x88/0x88
+
+
+The ``S`` and ``s`` specifiers are used for printing a pointer in symbolic
+format. They result in the symbol name with (S) or without (s)
+offsets. If KALLSYMS are disabled then the symbol address is printed instead.
+
+Note, that the ``F`` and ``f`` specifiers are identical to ``S`` (``s``)
+and thus deprecated. We have ``F`` and ``f`` because on ia64, ppc64 and
+parisc64 function pointers are indirect and, in fact, are function
+descriptors, which require additional dereferencing before we can lookup
+the symbol. As of now, ``S`` and ``s`` perform dereferencing on those
+platforms (when needed), so ``F`` and ``f`` exist for compatibility
+reasons only.
+
+The ``B`` specifier results in the symbol name with offsets and should be
+used when printing stack backtraces. The specifier takes into
+consideration the effect of compiler optimisations which may occur
+when tail-calls are used and marked with the noreturn GCC attribute.
+
+Kernel Pointers
+---------------
+
+::
+
+ %pK 01234567 or 0123456789abcdef
+
+For printing kernel pointers which should be hidden from unprivileged
+users. The behaviour of %pK depends on the kptr_restrict sysctl - see
+Documentation/sysctl/kernel.txt for more details.
+
+Unmodified Addresses
+--------------------
+
+::
+
+ %px 01234567 or 0123456789abcdef
+
+For printing pointers when you *really* want to print the address. Please
+consider whether or not you are leaking sensitive information about the
+kernel memory layout before printing pointers with %px. %px is functionally
+equivalent to %lx (or %lu). %px is preferred because it is more uniquely
+grep'able. If in the future we need to modify the way the kernel handles
+printing pointers we will be better equipped to find the call sites.
+
+Struct Resources
+----------------
+

+
+For printing struct resources. The ``R`` and ``r`` specifiers result in a

+
+Passed by reference.
+
+Physical address types phys_addr_t
+----------------------------------
+
+::
+
+ %pa[p] 0x01234567 or 0x0123456789abcdef
+
+For printing a phys_addr_t type (and its derivatives, such as
+resource_size_t) which can vary based on build options, regardless of the
+width of the CPU data path.
+
+Passed by reference.
+
+DMA address types dma_addr_t
+----------------------------
+
+::
+
+ %pad 0x01234567 or 0x0123456789abcdef
+
+For printing a dma_addr_t type which can vary based on build options,
+regardless of the width of the CPU data path.
+
+Passed by reference.
+
+Raw buffer as an escaped string
+-------------------------------
+
+::
+
+ %*pE[achnops]
+
+For printing raw buffer as an escaped string. For the following buffer::
+
+ 1b 62 20 5c 43 07 22 90 0d 5d
+
+A few examples show how the conversion would be done (excluding surrounding
+quotes)::
+
+ %*pE "\eb \C\a"\220\r]"
+ %*pEhp "\x1bb \C\x07"\x90\x0d]"
+ %*pEa "\e\142\040\\\103\a\042\220\r\135"
+
+The conversion rules are applied according to an optional combination
+of flags (see :c:func:`string_escape_mem` kernel documentation for the
+details):
+
+ - a - ESCAPE_ANY
+ - c - ESCAPE_SPECIAL
+ - h - ESCAPE_HEX
+ - n - ESCAPE_NULL
+ - o - ESCAPE_OCTAL
+ - p - ESCAPE_NP
+ - s - ESCAPE_SPACE
+
+By default ESCAPE_ANY_NP is used.
+
+ESCAPE_ANY_NP is the sane choice for many cases, in particularly for
+printing SSIDs.
+
+If field width is omitted then 1 byte only will be escaped.
+
+Raw buffer as a hex string
+--------------------------
+
+::
+
+ %*ph 00 01 02 ... 3f
+ %*phC 00:01:02: ... :3f
+ %*phD 00-01-02- ... -3f
+ %*phN 000102 ... 3f
+
+For printing small buffers (up to 64 bytes long) as a hex string with a
+certain separator. For larger buffers consider using
+:c:func:`print_hex_dump`.
+
+MAC/FDDI addresses
+------------------
+
+::
+
+ %pM 00:01:02:03:04:05
+ %pMR 05:04:03:02:01:00
+ %pMF 00-01-02-03-04-05
+ %pm 000102030405
+ %pmR 050403020100
+
+For printing 6-byte MAC/FDDI addresses in hex notation. The ``M`` and ``m``
+specifiers result in a printed address with (M) or without (m) byte
+separators. The default byte separator is the colon (:).
+
+Where FDDI addresses are concerned the ``F`` specifier can be used after
+the ``M`` specifier to use dash (-) separators instead of the default
+separator.
+
+For Bluetooth addresses the ``R`` specifier shall be used after the ``M``
+specifier to use reversed byte order suitable for visual interpretation
+of Bluetooth addresses which are in the little endian order.
+
+Passed by reference.
+
+IPv4 addresses
+--------------
+
+::
+
+ %pI4 1.2.3.4
+ %pi4 001.002.003.004
+ %p[Ii]4[hnbl]
+
+For printing IPv4 dot-separated decimal addresses. The ``I4`` and ``i4``
+specifiers result in a printed address with (i4) or without (I4) leading
+zeros.
+
+The additional ``h``, ``n``, ``b``, and ``l`` specifiers are used to specify
+host, network, big or little endian order addresses respectively. Where
+no specifier is provided the default network/big endian order is used.
+
+Passed by reference.
+
+IPv6 addresses
+--------------

+ %pI6c 1:2:3:4:5:6:7:8
+
+For printing IPv6 network-order 16-bit hex addresses. The ``I6`` and ``i6``
+specifiers result in a printed address with (I6) or without (i6)
+colon-separators. Leading zeros are always used.
+
+The additional ``c`` specifier can be used with the ``I`` specifier to
+print a compressed IPv6 address as described by
+http://tools.ietf.org/html/rfc5952
+
+Passed by reference.
+
+IPv4/IPv6 addresses (generic, with port, flowinfo, scope)
+---------------------------------------------------------

+ %pISpc 1.2.3.4:12345 or [1:2:3:4:5:6:7:8]:12345
+ %p[Ii]S[pfschnbl]
+
+For printing an IP address without the need to distinguish whether it's of
+type AF_INET or AF_INET6. A pointer to a valid struct sockaddr,
+specified through ``IS`` or ``iS``, can be passed to this format specifier.
+
+The additional ``p``, ``f``, and ``s`` specifiers are used to specify port
+(IPv4, IPv6), flowinfo (IPv6) and scope (IPv6). Ports have a ``:`` prefix,
+flowinfo a ``/`` and scope a ``%``, each followed by the actual value.
+
+In case of an IPv6 address the compressed IPv6 address as described by
+http://tools.ietf.org/html/rfc5952 is being used if the additional
+specifier ``c`` is given. The IPv6 address is surrounded by ``[``, ``]`` in
+case of additional specifiers ``p``, ``f`` or ``s`` as suggested by
+https://tools.ietf.org/html/draft-ietf-6man-text-addr-representation-07
+
+In case of IPv4 addresses, the additional ``h``, ``n``, ``b``, and ``l``
+specifiers can be used as well and are ignored in case of an IPv6
+address.

+ %pUL 03020100-0504-0706-0809-0A0B0C0E0E0F
+
+For printing 16-byte UUID/GUIDs addresses. The additional ``l``, ``L``,
+``b`` and ``B`` specifiers are used to specify a little endian order in
+lower (l) or upper case (L) hex notation - and big endian order in lower (b)
+or upper case (B) hex notation.
+
+Where no additional specifiers are used the default big endian
+order with lower case hex notation will be printed.

+
+dentry names
+------------
+
+::
+
+ %pd{,2,3,4}
+ %pD{,2,3,4}
+
+For printing dentry name; if we race with :c:func:`d_move`, the name might
+be a mix of old and new ones, but it won't oops. %pd dentry is a safer
+equivalent of %s dentry->d_name.name we used to use, %pd<n> prints ``n``
+last components. %pD does the same thing for struct file.
+
+Passed by reference.
+
+block_device names

+
+Passed by reference.
+
+kobjects
+--------
+
+::
+
+ %pOF[fnpPcCF]
+
+
+For printing kobject based structs (device nodes). Default behaviour is
+equivalent to %pOFf.
+
+ - f - device node full_name
+ - n - device node name
+ - p - device node phandle
+ - P - device node path spec (name + @unit)
+ - F - device node flags

+ %pGv read|exec|mayread|maywrite|mayexec|denywrite
+
+For printing flags bitfields as a collection of symbolic constants that

+===================================
+refcount_t API compared to atomic_t
+===================================
+
+.. contents:: :local:
+
+Introduction
+============
+
+The goal of refcount_t API is to provide a minimal API for implementing
+an object's reference counters. While a generic architecture-independent
+implementation from lib/refcount.c uses atomic operations underneath,
+there are a number of differences between some of the ``refcount_*()`` and
+``atomic_*()`` functions with regards to the memory ordering guarantees.
+This document outlines the differences and provides respective examples
+in order to help maintainers validate their code against the change in
+these memory ordering guarantees.
+
+The terms used through this document try to follow the formal LKMM defined in
+github.com/aparri/memory-model/blob/master/Documentation/explanation.txt
+
+memory-barriers.txt and atomic_t.txt provide more background to the
+memory ordering in general and for atomic operations specifically.
+
+Relevant types of memory ordering
+=================================
+
+.. note:: The following section only covers some of the memory
+ ordering types that are relevant for the atomics and reference
+ counters and used through this document. For a much broader picture
+ please consult memory-barriers.txt document.
+
+In the absence of any memory ordering guarantees (i.e. fully unordered)
+atomics & refcounters only provide atomicity and
+program order (po) relation (on the same CPU). It guarantees that
+each ``atomic_*()`` and ``refcount_*()`` operation is atomic and instructions
+are executed in program order on a single CPU.
+This is implemented using :c:func:`READ_ONCE`/:c:func:`WRITE_ONCE` and
+compare-and-swap primitives.
+
+A strong (full) memory ordering guarantees that all prior loads and
+stores (all po-earlier instructions) on the same CPU are completed
+before any po-later instruction is executed on the same CPU.
+It also guarantees that all po-earlier stores on the same CPU
+and all propagated stores from other CPUs must propagate to all
+other CPUs before any po-later instruction is executed on the original
+CPU (A-cumulative property). This is implemented using :c:func:`smp_mb`.
+
+A RELEASE memory ordering guarantees that all prior loads and
+stores (all po-earlier instructions) on the same CPU are completed
+before the operation. It also guarantees that all po-earlier
+stores on the same CPU and all propagated stores from other CPUs
+must propagate to all other CPUs before the release operation
+(A-cumulative property). This is implemented using
+:c:func:`smp_store_release`.
+
+A control dependency (on success) for refcounters guarantees that
+if a reference for an object was successfully obtained (reference
+counter increment or addition happened, function returned true),
+then further stores are ordered against this operation.
+Control dependency on stores are not implemented using any explicit
+barriers, but rely on CPU not to speculate on stores. This is only
+a single CPU relation and provides no guarantees for other CPUs.

+Introduction
+============
+
+The device-mapper "unstriped" target provides a transparent mechanism to
+unstripe a device-mapper "striped" target to access the underlying disks
+without having to touch the true backing block-device. It can also be
+used to unstripe a hardware RAID-0 to access backing disks.
+
+Parameters:
+<number of stripes> <chunk size> <stripe #> <dev_path> <offset>
+
+<number of stripes>
+ The number of stripes in the RAID 0.
+
+<chunk size>
+ The amount of 512B sectors in the chunk striping.
+
+<dev_path>
+ The block device you wish to unstripe.
+
+<stripe #>
+ The stripe number within the device that corresponds to physical
+ drive you wish to unstripe. This must be 0 indexed.
+
+
+Why use this module?
+====================
+
+An example of undoing an existing dm-stripe
+-------------------------------------------
+
+This small bash script will setup 4 loop devices and use the existing
+striped target to combine the 4 devices into one. It then will use
+the unstriped target ontop of the striped device to access the
+individual backing loop devices. We write data to the newly exposed
+unstriped devices and verify the data written matches the correct
+underlying device on the striped array.

+Another example
+---------------
+
+Intel NVMe drives contain two cores on the physical device.
+Each core of the drive has segregated access to its LBA range.
+The current LBA model has a RAID 0 128k chunk on each core, resulting
+in a 256k stripe across the two cores:
+
+ Core 0: Core 1:
+ __________ __________
+ | LBA 512| | LBA 768|
+ | LBA 0 | | LBA 256|
+ ---------- ----------
+
+The purpose of this unstriping is to provide better QoS in noisy
+neighbor environments. When two partitions are created on the
+aggregate drive without this unstriping, reads on one partition
+can affect writes on another partition. This is because the partitions
+are striped across the two cores. When we unstripe this hardware RAID 0
+and make partitions on each new exposed device the two partitions are now
+physically separated.
+
+With the dm-unstriped target we're able to segregate an fio script that
+has read and write jobs that are independent of each other. Compared to
+when we run the test on a combined drive with partitions, we were able
+to get a 92% reduction in read latency using this device mapper target.
+
+
+Example dmsetup usage
+=====================
+
+unstriped ontop of Intel NVMe device that has 2 cores
+-----------------------------------------------------
+dmsetup create nvmset0 --table '0 512 unstriped 2 256 0 /dev/nvme0n1 0'
+dmsetup create nvmset1 --table '0 512 unstriped 2 256 1 /dev/nvme0n1 0'
+
+There will now be two devices that expose Intel NVMe core 0 and 1
+respectively:
+/dev/mapper/nvmset0
+/dev/mapper/nvmset1
+
+unstriped ontop of striped with 4 drives using 128K chunk size
+--------------------------------------------------------------
+dmsetup create raid_disk0 --table '0 512 unstriped 4 256 0 /dev/mapper/striped 0'
+dmsetup create raid_disk1 --table '0 512 unstriped 4 256 1 /dev/mapper/striped 0'
+dmsetup create raid_disk2 --table '0 512 unstriped 4 256 2 /dev/mapper/striped 0'

+* Software Delegated Exception Interface (SDEI)
+
+Firmware implementing the SDEI functions described in ARM document number
+ARM DEN 0054A ("Software Delegated Exception Interface") can be used by
+Linux to receive notification of events such as those generated by
+firmware-first error handling, or from an IRQ that has been promoted to
+a firmware-assisted NMI.
+
+The interface provides a number of API functions for registering callbacks
+and enabling/disabling events. Functions are invoked by trapping to the
+privilege level of the SDEI firmware (specified as part of the binding
+below) and passing arguments in a manner specified by the "SMC Calling
+Convention (ARM DEN 0028B):
+
+ r0 => 32-bit Function ID / return value
+ {r1 - r3} => Parameters
+
+Note that the immediate field of the trapping instruction must be set
+to #0.
+
+The SDEI_EVENT_REGISTER function registers a callback in the kernel
+text to handle the specified event number.
+
+The sdei node should be a child node of '/firmware' and have required
+properties:
+
+ - compatible : should contain:
+ * "arm,sdei-1.0" : For implementations complying to SDEI version 1.x.
+
+ - method : The method of calling the SDEI firmware. Permitted
+ values are:
+ * "smc" : SMC #0, with the register assignments specified in this
+ binding.
+ * "hvc" : HVC #0, with the register assignments specified in this
+ binding.
+Example:
+ firmware {
+ sdei {
+ compatible = "arm,sdei-1.0";
+ method = "smc";
+ };

+
+ - compatible: Must be a "<manufacturer>,<model>" pair. The following <model>
+ values are supported (assuming "atmel" as manufacturer):
+
+ "atmel,24c00",
+ "atmel,24c01",
+ "atmel,24cs01",
+ "atmel,24c02",

+ "atmel,24c128",
+ "atmel,24c256",
+ "atmel,24c512",
+ "atmel,24c1024",
+
+ If <manufacturer> is not "atmel", then a fallback must be used
+ with the same <model> and "atmel" as manufacturer.
+
+ Example:
+ compatible = "microchip,24c128", "atmel,24c128";
+
+ Supported manufacturers are:
+
+ "catalyst",
+ "microchip",
+ "ramtron",
+ "renesas",
+ "nxp",
+ "st",
+
+ Some vendors use different model names for chips which are just
+ variants of the above. Known such exceptions are listed below:
+
+ "renesas,r1ex24002" - the fallback is "atmel,24c02"
+
+ - reg: The I2C address of the EEPROM.
+
+Optional properties:
+
+ - pagesize: The length of the pagesize for writing. Please consult the
+ manual of your device, that value varies a lot. A wrong value
+ may result in data loss! If not specified, a safety value of
+ '1' is used which will be very slow.
+
+ - read-only: This parameterless property disables writes to the eeprom.
+
+ - size: Total eeprom size in bytes.
+
+ - no-read-rollover: This parameterless property indicates that the
+ multi-address eeprom does not automatically roll over
+ reads to the next slave address. Please consult the
+ manual of your device.
+
+ - wp-gpios: GPIO to which the write-protect pin of the chip is connected.
+
+Example:
+
+eeprom@52 {
+ compatible = "atmel,24c32";
+ reg = <0x52>;
+ pagesize = <32>;
+ wp-gpios = <&gpio1 3 0>;

+STMicroelectronics STM32 DFSDM ADC device driver
+
+
+STM32 DFSDM ADC is a sigma delta analog-to-digital converter dedicated to
+interface external sigma delta modulators to STM32 micro controllers.
+It is mainly targeted for:
+- Sigma delta modulators (motor control, metering...)
+- PDM microphones (audio digital microphone)
+
+It features up to 8 serial digital interfaces (SPI or Manchester) and
+up to 4 filters on stm32h7.
+
+Each child node match with a filter instance.
+
+Contents of a STM32 DFSDM root node:
+------------------------------------
+Required properties:
+- compatible: Should be "st,stm32h7-dfsdm".
+- reg: Offset and length of the DFSDM block register set.
+- clocks: IP and serial interfaces clocking. Should be set according
+ to rcc clock ID and "clock-names".
+- clock-names: Input clock name "dfsdm" must be defined,
+ "audio" is optional. If defined CLKOUT is based on the audio
+ clock, else "dfsdm" is used.
+- #interrupt-cells = <1>;
+- #address-cells = <1>;
+- #size-cells = <0>;
+
+Optional properties:
+- spi-max-frequency: Requested only for SPI master mode.
+ SPI clock OUT frequency (Hz). This clock must be set according
+ to "clock" property. Frequency must be a multiple of the rcc
+ clock frequency. If not, SPI CLKOUT frequency will not be
+ accurate.
+
+Contents of a STM32 DFSDM child nodes:
+--------------------------------------
+
+Required properties:
+- compatible: Must be:
+ "st,stm32-dfsdm-adc" for sigma delta ADCs
+ "st,stm32-dfsdm-dmic" for audio digital microphone.
+- reg: Specifies the DFSDM filter instance used.
+- interrupts: IRQ lines connected to each DFSDM filter instance.
+- st,adc-channels: List of single-ended channels muxed for this ADC.
+ valid values:
+ "st,stm32h7-dfsdm" compatibility: 0 to 7.
+- st,adc-channel-names: List of single-ended channel names.
+- st,filter-order: SinC filter order from 0 to 5.
+ 0: FastSinC
+ [1-5]: order 1 to 5.
+ For audio purpose it is recommended to use order 3 to 5.
+- #io-channel-cells = <1>: See the IIO bindings section "IIO consumers".
+
+Required properties for "st,stm32-dfsdm-adc" compatibility:
+- io-channels: From common IIO binding. Used to pipe external sigma delta
+ modulator or internal ADC output to DFSDM channel.
+ This is not required for "st,stm32-dfsdm-pdm" compatibility as
+ PDM microphone is binded in Audio DT node.
+
+Required properties for "st,stm32-dfsdm-pdm" compatibility:
+- #sound-dai-cells: Must be set to 0.
+- dma: DMA controller phandle and DMA request line associated to the
+ filter instance (specified by the field "reg")
+- dma-names: Must be "rx"
+
+Optional properties:
+- st,adc-channel-types: Single-ended channel input type.
+ - "SPI_R": SPI with data on rising edge (default)
+ - "SPI_F": SPI with data on falling edge
+ - "MANCH_R": manchester codec, rising edge = logic 0
+ - "MANCH_F": manchester codec, falling edge = logic 1
+- st,adc-channel-clk-src: Conversion clock source.
+ - "CLKIN": external SPI clock (CLKIN x)
+ - "CLKOUT": internal SPI clock (CLKOUT) (default)
+ - "CLKOUT_F": internal SPI clock divided by 2 (falling edge).
+ - "CLKOUT_R": internal SPI clock divided by 2 (rising edge).
+
+- st,adc-alt-channel: Must be defined if two sigma delta modulator are
+ connected on same SPI input.
+ If not set, channel n is connected to SPI input n.
+ If set, channel n is connected to SPI input n + 1.
+
+- st,filter0-sync: Set to 1 to synchronize with DFSDM filter instance 0.
+ Used for multi microphones synchronization.
+
+Example of a sigma delta adc connected on DFSDM SPI port 0
+and a pdm microphone connected on DFSDM SPI port 1:
+
+ ads1202: simple_sd_adc@0 {
+ compatible = "ads1202";

+- reg: NAND flash controller memory area.
+- #address-cells: shall be set to 1. Encode the NAND CS.

+- interrupts: shall define the NAND controller interrupt.
+- clocks: shall reference the NAND controller clock.

+- label: MTD name.
+- nand-on-flash-bbt: see nand.txt.
+- nand-ecc-mode: see nand.txt. Will use hardware ECC if not specified.
+- nand-ecc-algo: see nand.txt. This property is essentially useful when
+ not using hardware ECC. Howerver, it may be added when using hardware
+ ECC for clarification but will be ignored by the driver because ECC
+ mode is chosen depending on the page size and the strength required by
+ the NAND chip. This value may be overwritten with nand-ecc-strength
+ property.
+- nand-ecc-strength: see nand.txt.
+- nand-ecc-step-size: see nand.txt. Marvell's NAND flash controller does
+ use fixed strength (1-bit for Hamming, 16-bit for BCH), so the actual
+ step size will shrink or grow in order to fit the required strength.
+ Step sizes are not completely random for all and follow certain
+ patterns described in AN-379, "Marvell SoC NFC ECC".
+
+See Documentation/devicetree/bindings/mtd/nand.txt for more details on
+generic bindings.

+
+
+Note on legacy bindings: One can find, in not-updated device trees,
+bindings slightly different than described above with other properties
+described below as well as the partitions node at the root of a so
+called "nand" node (without clear controller/chip separation).
+
+Legacy properties:
+- marvell,nand-enable-arbiter: To enable the arbiter, all boards blindly
+ used it, this bit was set by the bootloader for many boards and even if
+ it is marked reserved in several datasheets, it might be needed to set
+ it (otherwise it is harmless) so whether or not this property is set,
+ the bit is selected by the driver.
+- num-cs: Number of chip-select lines to use, all boards blindly set 1
+ to this and for a reason, other values would have failed. The value of
+ this property is ignored.

+Cortina Systems Gemini Ethernet Controller
+==========================================
+
+This ethernet controller is found in the Gemini SoC family:
+StorLink SL3512 and SL3516, also known as Cortina Systems
+CS3512 and CS3516.
+
+Required properties:
+- compatible: must be "cortina,gemini-ethernet"
+- reg: must contain the global registers and the V-bit and A-bit
+ memory areas, in total three register sets.
+- syscon: a phandle to the system controller
+- #address-cells: must be specified, must be <1>
+- #size-cells: must be specified, must be <1>
+- ranges: should be state like this giving a 1:1 address translation
+ for the subnodes
+
+The subnodes represents the two ethernet ports in this device.
+They are not independent of each other since they share resources
+in the parent node, and are thus children.
+
+Required subnodes:
+- port0: contains the resources for ethernet port 0
+- port1: contains the resources for ethernet port 1
+
+Required subnode properties:
+- compatible: must be "cortina,gemini-ethernet-port"
+- reg: must contain two register areas: the DMA/TOE memory and
+ the GMAC memory area of the port
+- interrupts: should contain the interrupt line of the port.
+ this is nominally a level interrupt active high.
+- resets: this must provide an SoC-integrated reset line for
+ the port.
+- clocks: this should contain a handle to the PCLK clock for
+ clocking the silicon in this port
+- clock-names: must be "PCLK"
+
+Optional subnode properties:
+- phy-mode: see ethernet.txt
+- phy-handle: see ethernet.txt
+

+Texas Instruments OMAP compatible OPP supply description
+
+OMAP5, DRA7, and AM57 family of SoCs have Class0 AVS eFuse registers which
+contain data that can be used to adjust voltages programmed for some of their
+supplies for more efficient operation. This binding provides the information
+needed to read these values and use them to program the main regulator during
+an OPP transitions.
+
+Also, some supplies may have an associated vbb-supply which is an Adaptive Body
+Bias regulator which much be transitioned in a specific sequence with regards
+to the vdd-supply and clk when making an OPP transition. By supplying two
+regulators to the device that will undergo OPP transitions we can make use
+of the multi regulator binding that is part of the OPP core described here [1]
+to describe both regulators needed by the platform.
+
+[1] Documentation/devicetree/bindings/opp/opp.txt
+
+Required Properties for Device Node:
+- vdd-supply: phandle to regulator controlling VDD supply
+- vbb-supply: phandle to regulator controlling Body Bias supply
+ (Usually Adaptive Body Bias regulator)
+
+Required Properties for opp-supply node:
+- compatible: Should be one of:
+ "ti,omap-opp-supply" - basic OPP supply controlling VDD and VBB
+ "ti,omap5-opp-supply" - OMAP5+ optimized voltages in efuse(class0)VDD
+ along with VBB
+ "ti,omap5-core-opp-supply" - OMAP5+ optimized voltages in efuse(class0) VDD
+ but no VBB.
+- reg: Address and length of the efuse register set for the device (mandatory
+ only for "ti,omap5-opp-supply")
+- ti,efuse-settings: An array of u32 tuple items providing information about
+ optimized efuse configuration. Each item consists of the following:
+ volt: voltage in uV - reference voltage (OPP voltage)
+ efuse_offseet: efuse offset from reg where the optimized voltage is stored.
+- ti,absolute-max-voltage-uv: absolute maximum voltage for the OPP supply.
+
+Example:
+
+/* Device Node (CPU) */
+cpus {
+ cpu0: cpu@0 {

+== MediaTek MT7622 pinctrl controller ==
+
+Required properties for the root node:
+ - compatible: Should be one of the following
+ "mediatek,mt7622-pinctrl" for MT7622 SoC
+ - reg: offset and length of the pinctrl space
+
+ - gpio-controller: Marks the device node as a GPIO controller.
+ - #gpio-cells: Should be two. The first cell is the pin number and the
+ second is the GPIO flags.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+MT7622 pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, slew rate, etc.
+
+We support 2 types of configuration nodes. Those nodes can be either pinmux
+nodes or pinconf nodes. Each configuration node can consist of multiple nodes
+describing the pinmux and pinconf options.
+
+The name of each subnode doesn't matter as long as it is unique; all subnodes
+should be enumerated and processed purely based on their content.
+
+== pinmux nodes content ==
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pinmux subnode:
+
+Required properties are:
+ - groups: An array of strings. Each string contains the name of a group.
+ Valid values for these names are listed below.
+ - function: A string containing the name of the function to mux to the
+ group. Valid values for function names are listed below.
+
+== pinconf nodes content ==
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pinconf subnode:
+
+Required properties are:
+ - pins: An array of strings. Each string contains the name of a pin.
+ Valid values for these names are listed below.
+ - groups: An array of strings. Each string contains the name of a group.
+ Valid values for these names are listed below.
+
+Optional properies are:
+ bias-disable, bias-pull, bias-pull-down, input-enable,
+ input-schmitt-enable, input-schmitt-disable, output-enable
+ output-low, output-high, drive-strength, slew-rate
+
+ Valid arguments for 'slew-rate' are '0' for no slew rate controlled and '1' for
+ slower slew rate respectively.
+ Valid arguments for 'drive-strength', 4, 8, 12, or 16 in mA.
+
+The following specific properties as defined are valid to specify in a pinconf
+subnode:
+
+Optional properties are:
+ - mediatek,tdsel: An integer describing the steps for output level shifter duty
+ cycle when asserted (high pulse width adjustment). Valid arguments are from 0
+ to 15.
+ - mediatek,rdsel: An integer describing the steps for input level shifter duty
+ cycle when asserted (high pulse width adjustment). Valid arguments are from 0
+ to 63.
+
+== Valid values for pins, function and groups on MT7622 ==
+
+Valid values for pins are:
+pins can be referenced via the pin names as the below table shown and the
+related physical number is also put ahead of those names which helps cross
+references to pins between groups to know whether pins assignment conflict
+happens among devices try to acquire those available pins.

+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+- pins:
+ Usage: required
+ Value type: <string-array>
+ Definition: List of gpio pins affected by the properties specified in
+ this subnode.
+
+ Valid pins are:
+ gpio0-gpio149
+ Supports mux, bias and drive-strength
+
+ sdc2_clk, sdc2_cmd, sdc2_data
+ Supports bias and drive-strength
+
+ ufs_reset
+ Supports bias and drive-strength
+
+- function:

+ specified pins. Functions are only valid for gpio pins.

+SLIM(Serial Low Power Interchip Media Bus) bus
+
+SLIMbus is a 2-wire bus, and is used to communicate with peripheral
+components like audio-codec.
+
+Required property for SLIMbus controller node:
+- compatible - name of SLIMbus controller
+
+Child nodes:
+Every SLIMbus controller node can contain zero or more child nodes
+representing slave devices on the bus. Every SLIMbus slave device is
+uniquely determined by the enumeration address containing 4 fields:
+Manufacturer ID, Product code, Device index, and Instance value for
+the device.
+If child node is not present and it is instantiated after device
+discovery (slave device reporting itself present).
+
+In some cases it may be necessary to describe non-probeable device
+details such as non-standard ways of powering up a device. In
+such cases, child nodes for those devices will be present as
+slaves of the SLIMbus controller, as detailed below.
+
+Required property for SLIMbus child node if it is present:
+- reg - Should be ('Device index', 'Instance ID') from SLIMbus
+ Enumeration Address.
+ Device Index Uniquely identifies multiple Devices within
+ a single Component.
+ Instance ID Is for the cases where multiple Devices of the
+ same type or Class are attached to the bus.
+
+- compatible -"slimMID,PID". The textual representation of Manufacturer ID,
+ Product Code, shall be in lower case hexadecimal with leading
+ zeroes suppressed
+
+SLIMbus example for Qualcomm's slimbus manager component:
+
+ slim@28080000 {
+ compatible = "qcom,apq8064-slim", "qcom,slim";
+ reg = <0x28080000 0x2000>,
+ interrupts = <0 33 0>;
+ clocks = <&lcc SLIMBUS_SRC>, <&lcc AUDIO_SLIMBUS_CLK>;
+ clock-names = "iface", "core";
+ #address-cells = <2>;
+ #size-cell = <0>;
+
+ codec: wcd9310@1,0{
+ compatible = "slim217,60";
+ reg = <1 0>;
+ };

+Parameters and member arguments
+-------------------------------
+
+The kernel-doc function comments describe each parameter to the function and
+function typedefs or each member of struct/union, in order, with the
+``@argument:`` descriptions. For each non-private member argument, one
+``@argument`` definition is needed.
+
+The ``@argument:`` descriptions begin on the very next line following
+the opening brief function description line, with no intervening blank
+comment lines.
+
+The ``@argument:`` descriptions may span multiple lines.
+
+.. note::
+
+ If the ``@argument`` description has multiple lines, the continuation
+ of the description should be starting exactly at the same column as
+ the previous line, e. g.::
+
+ * @argument: some long description
+ * that continues on next lines
+
+ or::
+
+ * @argument:
+ * some long description
+ * that continues on next lines
+
+If a function or typedef parameter argument is ``...`` (e. g. a variable
+number of arguments), its description should be listed in kernel-doc
+notation as::
+
+ * @...: description
+
+Private members
+~~~~~~~~~~~~~~~
+
+Inside a struct or union description, you can use the ``private:`` and
+``public:`` comment tags. Structure fields that are inside a ``private:``
+area are not listed in the generated output documentation.
+
+The ``private:`` and ``public:`` tags must begin immediately following a
+``/*`` comment marker. They may optionally include comments between the
+``:`` and the ending ``*/`` marker.
+
+Example::
+
+ /**
+ * struct my_struct - short description
+ * @a: first member
+ * @b: second member
+ * @d: fourth member
+ *
+ * Longer description

+Function documentation
+----------------------
+
+The general format of a function and function-like macro kernel-doc comment is::
+
+ /**
+ * function_name() - Brief description of function.
+ * @arg1: Describe the first argument.
+ * @arg2: Describe the second argument.
+ * One can provide multiple line descriptions
+ * for arguments.
+ *
+ * A longer description, with more discussion of the function function_name()
+ * that might be useful to those using or modifying it. Begins with an
+ * empty comment line, and may include additional embedded empty
+ * comment lines.
+ *
+ * The longer description may have multiple paragraphs.
+ *
+ * Return: Describe the return value of foobar.
+ *
+ * The return value description can also have multiple paragraphs, and should
+ * be placed at the end of the comment block.
+ */
+
+The brief description following the function name may span multiple lines, and
+ends with an argument description, a blank comment line, or the end of the
+comment block.
+
+Return values
+~~~~~~~~~~~~~
+
+The return value, if any, should be described in a dedicated section
+named ``Return``.
+
+.. note::
+
+ #) The multi-line descriptive text you provide does *not* recognize
+ line breaks, so if you try to format some text nicely, as in::
+
+ * Return:
+ * 0 - OK
+ * -EINVAL - invalid argument
+ * -ENOMEM - out of memory
+
+ this will all run together and produce::
+
+ Return: 0 - OK -EINVAL - invalid argument -ENOMEM - out of memory
+
+ So, in order to produce the desired line breaks, you need to use a
+ ReST list, e. g.::
+
+ * Return:
+ * * 0 - OK to runtime suspend the device
+ * * -EBUSY - Device should not be runtime suspended
+
+ #) If the descriptive text you provide has lines that begin with
+ some phrase followed by a colon, each of those phrases will be taken
+ as a new section heading, with probably won't produce the desired

+Structure, union, and enumeration documentation
+-----------------------------------------------
+
+The general format of a struct, union, and enum kernel-doc comment is::
+
+ /**
+ * struct struct_name - Brief description.
+ * @argument: Description of member member_name.
+ *
+ * Description of the structure.
+ */
+
+On the above, ``struct`` is used to mean structs. You can also use ``union``
+and ``enum`` to describe unions and enums. ``argument`` is used
+to mean struct and union member names as well as enumerations in an enum.
+
+The brief description following the structure name may span multiple lines, and
+ends with a member description, a blank comment line, or the end of the
+comment block.
+
+The kernel-doc data structure comments describe each member of the structure,
+in order, with the member descriptions.
+
+Nested structs/unions
+~~~~~~~~~~~~~~~~~~~~~
+
+It is possible to document nested structs unions, like::
+
+ /**

+ * @arg1: - first argument of anonymous union/anonymous struct
+ * @arg2: - second argument of anonymous union/anonymous struct

+ }
+ union {
+ struct {
+ int arg1;
+ int arg2;
+ } st1;
+ struct {

+ int arg2;
+ } st2;
+ } bar;
+ };
+
+.. note::
+
+ #) When documenting nested structs or unions, if the struct/union ``foo``

+The Industrial I/O HW consumer offers a way to bond these IIO devices without
+software buffer for data. The implementation can be found under

+
+
+HW consumer setup
+=================
+
+As standard IIO device the implementation is based on IIO provider/consumer.

+
+ static const struct iio_info adc_info = {

+However, it often is desirable to leave devices in suspend after system
+transitions to the working state, especially if those devices had been in
+runtime suspend before the preceding system-wide suspend (or analogous)
+transition. Device drivers can use the ``DPM_FLAG_LEAVE_SUSPENDED`` flag to
+indicate to the PM core (and middle-layer code) that they prefer the specific
+devices handled by them to be left suspended and they have no problems with
+skipping their system-wide resume callbacks for this reason. Whether or not the
+devices will actually be left in suspend may depend on their state before the
+given system suspend-resume cycle and on the type of the system transition under
+way. In particular, devices are not left suspended if that transition is a
+restore from hibernation, as device states are not guaranteed to be reflected
+by the information stored in the hibernation image in that case.
+
+The middle-layer code involved in the handling of the device is expected to
+indicate to the PM core if the device may be left in suspend by setting its
+:c:member:`power.may_skip_resume` status bit which is checked by the PM core
+during the "noirq" phase of the preceding system-wide suspend (or analogous)
+transition. The middle layer is then responsible for handling the device as
+appropriate in its "noirq" resume callback, which is executed regardless of
+whether or not the device is left suspended, but the other resume callbacks
+(except for ``->complete``) will be skipped automatically by the PM core if the
+device really can be left in suspend.
+
+For devices whose "noirq", "late" and "early" driver callbacks are invoked
+directly by the PM core, all of the system-wide resume callbacks are skipped if
+``DPM_FLAG_LEAVE_SUSPENDED`` is set and the device is in runtime suspend during
+the ``suspend_noirq`` (or analogous) phase or the transition under way is a
+proper system suspend (rather than anything related to hibernation) and the
+device's wakeup settings are suitable for runtime PM (that is, it cannot
+generate wakeup signals at all or it is allowed to wake up the system from
+sleep).

+============================
+Linux kernel SLIMbus support
+============================
+
+Overview
+========
+
+What is SLIMbus?
+----------------
+SLIMbus (Serial Low Power Interchip Media Bus) is a specification developed by
+MIPI (Mobile Industry Processor Interface) alliance. The bus uses master/slave
+configuration, and is a 2-wire multi-drop implementation (clock, and data).
+
+Currently, SLIMbus is used to interface between application processors of SoCs
+(System-on-Chip) and peripheral components (typically codec). SLIMbus uses
+Time-Division-Multiplexing to accommodate multiple data channels, and
+a control channel.
+
+The control channel is used for various control functions such as bus
+management, configuration and status updates. These messages can be unicast (e.g.
+reading/writing device specific values), or multicast (e.g. data channel
+reconfiguration sequence is a broadcast message announced to all devices)
+
+A data channel is used for data-transfer between 2 SLIMbus devices. Data
+channel uses dedicated ports on the device.
+
+Hardware description:
+---------------------
+SLIMbus specification has different types of device classifications based on
+their capabilities.
+A manager device is responsible for enumeration, configuration, and dynamic
+channel allocation. Every bus has 1 active manager.
+
+A generic device is a device providing application functionality (e.g. codec).
+
+Framer device is responsible for clocking the bus, and transmitting frame-sync
+and framing information on the bus.
+
+Each SLIMbus component has an interface device for monitoring physical layer.
+
+Typically each SoC contains SLIMbus component having 1 manager, 1 framer device,
+1 generic device (for data channel support), and 1 interface device.
+External peripheral SLIMbus component usually has 1 generic device (for
+functionality/data channel support), and an associated interface device.
+The generic device's registers are mapped as 'value elements' so that they can
+be written/read using SLIMbus control channel exchanging control/status type of
+information.
+In case there are multiple framer devices on the same bus, manager device is
+responsible to select the active-framer for clocking the bus.
+
+Per specification, SLIMbus uses "clock gears" to do power management based on
+current frequency and bandwidth requirements. There are 10 clock gears and each
+gear changes the SLIMbus frequency to be twice its previous gear.
+
+Each device has a 6-byte enumeration-address and the manager assigns every
+device with a 1-byte logical address after the devices report presence on the
+bus.
+
+Software description:
+---------------------
+There are 2 types of SLIMbus drivers:
+
+slim_controller represents a 'controller' for SLIMbus. This driver should
+implement duties needed by the SoC (manager device, associated
+interface device for monitoring the layers and reporting errors, default
+framer device).
+
+slim_device represents the 'generic device/component' for SLIMbus, and a
+slim_driver should implement driver for that slim_device.
+
+Device notifications to the driver:
+-----------------------------------
+Since SLIMbus devices have mechanisms for reporting their presence, the
+framework allows drivers to bind when corresponding devices report their
+presence on the bus.
+However, it is possible that the driver needs to be probed
+first so that it can enable corresponding SLIMbus device (e.g. power it up and/or
+take it out of reset). To support that behavior, the framework allows drivers
+to probe first as well (e.g. using standard DeviceTree compatibility field).
+This creates the necessity for the driver to know when the device is functional
+(i.e. reported present). device_up callback is used for that reason when the
+device reports present and is assigned a logical address by the controller.
+
+Similarly, SLIMbus devices 'report absent' when they go down. A 'device_down'
+callback notifies the driver when the device reports absent and its logical
+address assignment is invalidated by the controller.
+
+Another notification "boot_device" is used to notify the slim_driver when
+controller resets the bus. This notification allows the driver to take necessary
+steps to boot the device so that it's functional after the bus has been reset.
+

+ :internal:
+
+.. kernel-doc:: drivers/slimbus/slimbus.h
+ :internal:
+
+.. kernel-doc:: drivers/slimbus/core.c
+ :export:
+
+Clock-pause:
+------------
+SLIMbus mandates that a reconfiguration sequence (known as clock-pause) be
+broadcast to all active devices on the bus before the bus can enter low-power
+mode. Controller uses this sequence when it decides to enter low-power mode so
+that corresponding clocks and/or power-rails can be turned off to save power.
+Clock-pause is exited by waking up framer device (if controller driver initiates
+exiting low power mode), or by toggling the data line (if a slave device wants
+to initiate it).
+
+Clock-pause APIs:

+
+Messaging:
+----------
+The framework supports regmap and read/write apis to exchange control-information
+with a SLIMbus device. APIs can be synchronous or asynchronous.
+The header file <linux/slimbus.h> has more documentation about messaging APIs.

+===========================
+SoundWire Subsystem Summary
+===========================
+
+SoundWire is a new interface ratified in 2015 by the MIPI Alliance.
+SoundWire is used for transporting data typically related to audio
+functions. SoundWire interface is optimized to integrate audio devices in
+mobile or mobile inspired systems.
+
+SoundWire is a 2-pin multi-drop interface with data and clock line. It
+facilitates development of low cost, efficient, high performance systems.
+Broad level key features of SoundWire interface include:
+
+ (1) Transporting all of payload data channels, control information, and setup
+ commands over a single two-pin interface.
+
+ (2) Lower clock frequency, and hence lower power consumption, by use of DDR
+ (Dual Data Rate) data transmission.
+
+ (3) Clock scaling and optional multiple data lanes to give wide flexibility
+ in data rate to match system requirements.
+
+ (4) Device status monitoring, including interrupt-style alerts to the Master.
+
+The SoundWire protocol supports up to eleven Slave interfaces. All the
+interfaces share the common Bus containing data and clock line. Each of the
+Slaves can support up to 14 Data Ports. 13 Data Ports are dedicated to audio
+transport. Data Port0 is dedicated to transport of Bulk control information,
+each of the audio Data Ports (1..14) can support up to 8 Channels in
+transmit or receiving mode (typically fixed direction but configurable
+direction is enabled by the specification). Bandwidth restrictions to
+~19.2..24.576Mbits/s don't however allow for 11*13*8 channels to be
+transmitted simultaneously.
+
+Below figure shows an example of connectivity between a SoundWire Master and
+two Slave devices. ::

+
+Terminology
+===========
+
+The MIPI SoundWire specification uses the term 'device' to refer to a Master
+or Slave interface, which of course can be confusing. In this summary and
+code we use the term interface only to refer to the hardware. We follow the
+Linux device model by mapping each Slave interface connected on the bus as a
+device managed by a specific driver. The Linux SoundWire subsystem provides
+a framework to implement a SoundWire Slave driver with an API allowing
+3rd-party vendors to enable implementation-defined functionality while
+common setup/configuration tasks are handled by the bus.
+
+Bus:
+Implements SoundWire Linux Bus which handles the SoundWire protocol.
+Programs all the MIPI-defined Slave registers. Represents a SoundWire
+Master. Multiple instances of Bus may be present in a system.
+
+Slave:
+Registers as SoundWire Slave device (Linux Device). Multiple Slave devices
+can register to a Bus instance.
+
+Slave driver:
+Driver controlling the Slave device. MIPI-specified registers are controlled
+directly by the Bus (and transmitted through the Master driver/interface).
+Any implementation-defined Slave register is controlled by Slave driver. In
+practice, it is expected that the Slave driver relies on regmap and does not
+request direct register access.
+
+Programming interfaces (SoundWire Master interface Driver)
+==========================================================
+
+SoundWire Bus supports programming interfaces for the SoundWire Master
+implementation and SoundWire Slave devices. All the code uses the "sdw"
+prefix commonly used by SoC designers and 3rd party vendors.
+
+Each of the SoundWire Master interfaces needs to be registered to the Bus.
+Bus implements API to read standard Master MIPI properties and also provides
+callback in Master ops for Master driver to implement its own functions that
+provides capabilities information. DT support is not implemented at this
+time but should be trivial to add since capabilities are enabled with the
+``device_property_`` API.
+
+The Master interface along with the Master interface capabilities are
+registered based on board file, DT or ACPI.
+
+Following is the Bus API to register the SoundWire Bus:
+
+.. code-block:: c
+
+ int sdw_add_bus_master(struct sdw_bus *bus)
+ {
+ if (!bus->dev)
+ return -ENODEV;
+
+ mutex_init(&bus->lock);
+ INIT_LIST_HEAD(&bus->slaves);
+
+ /* Check ACPI for Slave devices */
+ sdw_acpi_find_slaves(bus);
+
+ /* Check DT for Slave devices */
+ sdw_of_find_slaves(bus);
+
+ return 0;
+ }
+
+This will initialize sdw_bus object for Master device. "sdw_master_ops" and
+"sdw_master_port_ops" callback functions are provided to the Bus.
+
+"sdw_master_ops" is used by Bus to control the Bus in the hardware specific
+way. It includes Bus control functions such as sending the SoundWire
+read/write messages on Bus, setting up clock frequency & Stream
+Synchronization Point (SSP). The "sdw_master_ops" structure abstracts the
+hardware details of the Master from the Bus.
+
+"sdw_master_port_ops" is used by Bus to setup the Port parameters of the
+Master interface Port. Master interface Port register map is not defined by
+MIPI specification, so Bus calls the "sdw_master_port_ops" callback
+function to do Port operations like "Port Prepare", "Port Transport params
+set", "Port enable and disable". The implementation of the Master driver can
+then perform hardware-specific configurations.
+
+Programming interfaces (SoundWire Slave Driver)
+===============================================
+
+The MIPI specification requires each Slave interface to expose a unique
+48-bit identifier, stored in 6 read-only dev_id registers. This dev_id
+identifier contains vendor and part information, as well as a field enabling
+to differentiate between identical components. An additional class field is
+currently unused. Slave driver is written for a specific vendor and part
+identifier, Bus enumerates the Slave device based on these two ids.
+Slave device and driver match is done based on these two ids . Probe
+of the Slave driver is called by Bus on successful match between device and
+driver id. A parent/child relationship is enforced between Master and Slave
+devices (the logical representation is aligned with the physical
+connectivity).
+
+The information on Master/Slave dependencies is stored in platform data,
+board-file, ACPI or DT. The MIPI Software specification defines additional
+link_id parameters for controllers that have multiple Master interfaces. The
+dev_id registers are only unique in the scope of a link, and the link_id
+unique in the scope of a controller. Both dev_id and link_id are not
+necessarily unique at the system level but the parent/child information is
+used to avoid ambiguity.
+
+.. code-block:: c
+
+ static const struct sdw_device_id slave_id[] = {
+ SDW_SLAVE_ENTRY(0x025d, 0x700, 0),
+ {},
+ };
+ MODULE_DEVICE_TABLE(sdw, slave_id);
+
+ static struct sdw_driver slave_sdw_driver = {
+ .driver = {
+ .name = "slave_xxx",
+ .pm = &slave_runtime_pm,
+ },
+ .probe = slave_sdw_probe,
+ .remove = slave_sdw_remove,
+ .ops = &slave_slave_ops,
+ .id_table = slave_id,
+ };
+
+
+For capabilities, Bus implements API to read standard Slave MIPI properties
+and also provides callback in Slave ops for Slave driver to implement own
+function that provides capabilities information. Bus needs to know a set of
+Slave capabilities to program Slave registers and to control the Bus
+reconfigurations.
+
+Future enhancements to be done
+==============================
+
+ (1) Bulk Register Access (BRA) transfers.
+
+
+ (2) Multiple data lane support.

-The errseq_t datatype
-=====================
-An errseq_t is a way of recording errors in one place, and allowing any
-number of "subscribers" to tell whether it has changed since a previous
-point where it was sampled.
-
-The initial use case for this is tracking errors for file
-synchronization syscalls (fsync, fdatasync, msync and sync_file_range),
-but it may be usable in other situations.
-
-It's implemented as an unsigned 32-bit value. The low order bits are
-designated to hold an error code (between 1 and MAX_ERRNO). The upper bits
-are used as a counter. This is done with atomics instead of locking so that
-these functions can be called from any context.
-
-Note that there is a risk of collisions if new errors are being recorded
-frequently, since we have so few bits to use as a counter.
-
-To mitigate this, the bit between the error value and counter is used as
-a flag to tell whether the value has been sampled since a new value was
-recorded. That allows us to avoid bumping the counter if no one has
-sampled it since the last time an error was recorded.
-
-Thus we end up with a value that looks something like this::
-
- bit: 31..13 12 11..0
- +-----------------+----+----------------+
- | counter | SF | errno |
- +-----------------+----+----------------+
-
-The general idea is for "watchers" to sample an errseq_t value and keep
-it as a running cursor. That value can later be used to tell whether
-any new errors have occurred since that sampling was done, and atomically
-record the state at the time that it was checked. This allows us to
-record errors in one place, and then have a number of "watchers" that
-can tell whether the value has changed since they last checked it.
-
-A new errseq_t should always be zeroed out. An errseq_t value of all zeroes
-is the special (but common) case where there has never been an error. An all
-zero value thus serves as the "epoch" if one wishes to know whether there
-has ever been an error set since it was first initialized.
-
-API usage
-=========
-Let me tell you a story about a worker drone. Now, he's a good worker
-overall, but the company is a little...management heavy. He has to
-report to 77 supervisors today, and tomorrow the "big boss" is coming in
-from out of town and he's sure to test the poor fellow too.
-
-They're all handing him work to do -- so much he can't keep track of who
-handed him what, but that's not really a big problem. The supervisors
-just want to know when he's finished all of the work they've handed him so
-far and whether he made any mistakes since they last asked.
-
-He might have made the mistake on work they didn't actually hand him,
-but he can't keep track of things at that level of detail, all he can
-remember is the most recent mistake that he made.
-
-Here's our worker_drone representation::
-
- struct worker_drone {
- errseq_t wd_err; /* for recording errors */
- };
-
-Every day, the worker_drone starts out with a blank slate::
-
- struct worker_drone wd;
-
- wd.wd_err = (errseq_t)0;
-
-The supervisors come in and get an initial read for the day. They
-don't care about anything that happened before their watch begins::
-
- struct supervisor {
- errseq_t s_wd_err; /* private "cursor" for wd_err */
- spinlock_t s_wd_err_lock; /* protects s_wd_err */
- }
-
- struct supervisor su;
-
- su.s_wd_err = errseq_sample(&wd.wd_err);
- spin_lock_init(&su.s_wd_err_lock);
-
-Now they start handing him tasks to do. Every few minutes they ask him to
-finish up all of the work they've handed him so far. Then they ask him
-whether he made any mistakes on any of it::
-
- spin_lock(&su.su_wd_err_lock);
- err = errseq_check_and_advance(&wd.wd_err, &su.s_wd_err);
- spin_unlock(&su.su_wd_err_lock);
-
-Up to this point, that just keeps returning 0.
-
-Now, the owners of this company are quite miserly and have given him
-substandard equipment with which to do his job. Occasionally it
-glitches and he makes a mistake. He sighs a heavy sigh, and marks it
-down::
-
- errseq_set(&wd.wd_err, -EIO);
-
-...and then gets back to work. The supervisors eventually poll again
-and they each get the error when they next check. Subsequent calls will
-return 0, until another error is recorded, at which point it's reported
-to each of them once.
-
-Note that the supervisors can't tell how many mistakes he made, only
-whether one was made since they last checked, and the latest value
-recorded.
-
-Occasionally the big boss comes in for a spot check and asks the worker
-to do a one-off job for him. He's not really watching the worker
-full-time like the supervisors, but he does need to know whether a
-mistake occurred while his job was processing.
-
-He can just sample the current errseq_t in the worker, and then use that
-to tell whether an error has occurred later::
-
- errseq_t since = errseq_sample(&wd.wd_err);
- /* submit some work and wait for it to complete */
- err = errseq_check(&wd.wd_err, since);
-
-Since he's just going to discard "since" after that point, he doesn't

-Serializing errseq_t cursor updates
-===================================
-Note that the errseq_t API does not protect the errseq_t cursor during a
-check_and_advance_operation. Only the canonical error code is handled
-atomically. In a situation where more than one task might be using the
-same errseq_t cursor at the same time, it's important to serialize
-updates to that cursor.
-
-If that's not done, then it's possible for the cursor to go backward
-in which case the same error could be reported more than once.
-
-Because of this, it's often advantageous to first do an errseq_check to
-see if anything has changed, and only later do an
-errseq_check_and_advance after taking the lock. e.g.::
-
- if (errseq_check(&wd.wd_err, READ_ONCE(su.s_wd_err)) {
- /* su.s_wd_err is protected by s_wd_err_lock */
- spin_lock(&su.s_wd_err_lock);
- err = errseq_check_and_advance(&wd.wd_err, &su.s_wd_err);
- spin_unlock(&su.s_wd_err_lock);
- }
-
-That avoids the spinlock in the common case where nothing has changed
-since the last time it was checked.

+match the origin file handle that was stored at copy_up time. If a
+found lower directory does not match the stored origin, that directory
+will not be merged with the upper directory.
+
+
+
+NFS export
+----------
+
+When the underlying filesystems supports NFS export and the "nfs_export"
+feature is enabled, an overlay filesystem may be exported to NFS.
+
+With the "nfs_export" feature, on copy_up of any lower object, an index
+entry is created under the index directory. The index entry name is the
+hexadecimal representation of the copy up origin file handle. For a
+non-directory object, the index entry is a hard link to the upper inode.
+For a directory object, the index entry has an extended attribute
+"trusted.overlay.upper" with an encoded file handle of the upper
+directory inode.
+
+When encoding a file handle from an overlay filesystem object, the
+following rules apply:
+
+1. For a non-upper object, encode a lower file handle from lower inode
+2. For an indexed object, encode a lower file handle from copy_up origin
+3. For a pure-upper object and for an existing non-indexed upper object,
+ encode an upper file handle from upper inode
+
+The encoded overlay file handle includes:
+ - Header including path type information (e.g. lower/upper)
+ - UUID of the underlying filesystem
+ - Underlying filesystem encoding of underlying inode
+
+This encoding format is identical to the encoding format file handles that
+are stored in extended attribute "trusted.overlay.origin".
+
+When decoding an overlay file handle, the following steps are followed:
+
+1. Find underlying layer by UUID and path type information.
+2. Decode the underlying filesystem file handle to underlying dentry.
+3. For a lower file handle, lookup the handle in index directory by name.
+4. If a whiteout is found in index, return ESTALE. This represents an
+ overlay object that was deleted after its file handle was encoded.
+5. For a non-directory, instantiate a disconnected overlay dentry from the
+ decoded underlying dentry, the path type and index inode, if found.
+6. For a directory, use the connected underlying decoded dentry, path type
+ and index, to lookup a connected overlay dentry.
+
+Decoding a non-directory file handle may return a disconnected dentry.
+copy_up of that disconnected dentry will create an upper index entry with
+no upper alias.
+
+When overlay filesystem has multiple lower layers, a middle layer
+directory may have a "redirect" to lower directory. Because middle layer
+"redirects" are not indexed, a lower file handle that was encoded from the
+"redirect" origin directory, cannot be used to find the middle or upper
+layer directory. Similarly, a lower file handle that was encoded from a
+descendant of the "redirect" origin directory, cannot be used to
+reconstruct a connected overlay path. To mitigate the cases of
+directories that cannot be decoded from a lower file handle, these
+directories are copied up on encode and encoded as an upper file handle.
+On an overlay filesystem with no upper layer this mitigation cannot be
+used NFS export in this setup requires turning off redirect follow (e.g.
+"redirect_dir=nofollow").
+
+The overlay filesystem does not support non-directory connectable file
+handles, so exporting with the 'subtree_check' exportfs configuration will
+cause failures to lookup files over NFS.
+
+When the NFS export feature is enabled, all directory index entries are
+verified on mount time to check that upper file handles are not stale.
+This verification may cause significant overhead in some cases.

The FPGA image data itself is very manufacturer specific, but for our purposes
it's just binary data. The FPGA manager core won't parse it.
+The FPGA image to be programmed can be in a scatter gather list, a single
+contiguous buffer, or a firmware file. Because allocating contiguous kernel
+memory for the buffer should be avoided, users are encouraged to use a scatter
+gather list instead if possible.

+The particulars for programming the image are presented in a structure (struct

+an FPGA Manager and a bridge (or bridges) with a reprogrammable region of an
+FPGA or the whole FPGA. The API provides a way to register a region and to
+program a region.
+
+Currently the only layer above fpga-region.c in the kernel is the Device Tree
+support (of-fpga-region.c) described in [1]. The DT support layer uses regions
+to program the FPGA and then DT to handle enumeration. The common region code
+is intended to be used by other schemes that have other ways of accomplishing
+enumeration after programming.
+
+An fpga-region can be set up to know the following things:
+* which FPGA manager to use to do the programming
+* which bridges to disable before programming and enable afterwards.
+
+Additional info needed to program the FPGA image is passed in the struct
+fpga_image_info [2] including:
+* pointers to the image as either a scatter-gather buffer, a contiguous
+ buffer, or the name of firmware file
+* flags indicating specifics such as whether the image if for partial
+ reconfiguration.
+
+===================
+The FPGA region API
+===================
+
+To register or unregister a region:
+-----------------------------------
+
+ int fpga_region_register(struct device *dev,
+ struct fpga_region *region);
+ int fpga_region_unregister(struct fpga_region *region);
+
+An example of usage can be seen in the probe function of [3]
+
+To program an FPGA:
+-------------------
+ int fpga_region_program_fpga(struct fpga_region *region);
+
+This function operates on info passed in the fpga_image_info
+(region->info).
+
+This function will attempt to:
+ * lock the region's mutex
+ * lock the region's FPGA manager
+ * build a list of FPGA bridges if a method has been specified to do so
+ * disable the bridges
+ * program the FPGA
+ * re-enable the bridges
+ * release the locks
+
+=============
+Usage example
+=============
+
+First, allocate the info struct:
+
+ info = fpga_image_info_alloc(dev);
+ if (!info)
+ return -ENOMEM;
+
+Set flags as needed, i.e.
+
+ info->flags |= FPGA_MGR_PARTIAL_RECONFIG;
+
+Point to your FPGA image, such as:
+
+ info->sgt = &sgt;
+
+Add info to region and do the programming:
+
+ region->info = info;
+ ret = fpga_region_program_fpga(region);
+
+Then enumerate whatever hardware has appeared in the FPGA.

+Linux kernel FPGA support
+
+Alan Tull 2017
+
+The main point of this project has been to separate the out the upper layers
+that know when to reprogram a FPGA from the lower layers that know how to
+reprogram a specific FPGA device. The intention is to make this manufacturer
+agnostic, understanding that of course the FPGA images are very device specific
+themselves.
+
+The framework in the kernel includes:
+* low level FPGA manager drivers that know how to program a specific device
+* the fpga-mgr framework they are registered with
+* low level FPGA bridge drivers for hard/soft bridges which are intended to
+ be disable during FPGA programming
+* the fpga-bridge framework they are registered with
+* the fpga-region framework which associates and controls managers and bridges
+ as reconfigurable regions
+* the of-fpga-region support for reprogramming FPGAs when device tree overlays
+ are applied.
+
+I would encourage you the user to add code that creates FPGA regions rather
+that trying to control managers and bridges separately.

-Active-low State and Raw GPIO Values
-------------------------------------
-Device drivers like to manage the logical state of a GPIO, i.e. the value their
-device will actually receive, no matter what lies between it and the GPIO line.
-In some cases, it might make sense to control the actual GPIO line value. The

+The active low and open drain semantics
+---------------------------------------
+As a consumer should not have to care about the physical line level, all of the
+gpiod_set_value_xxx() or gpiod_set_array_value_xxx() functions operate with
+the *logical* value. With this they take the active low property into account.
+This means that they check whether the GPIO is configured to be active low,
+and if so, they manipulate the passed value before the physical line level is
+driven.
+
+The same is applicable for open drain or open source output lines: those do not
+actively drive their output high (open drain) or low (open source), they just
+switch their output to a high impedance value. The consumer should not need to
+care. (For details read about open drain in driver.txt.)
+
+With this, all the gpiod_set_(array)_value_xxx() functions interpret the
+parameter "value" as "asserted" ("1") or "de-asserted" ("0"). The physical line
+level will be driven accordingly.
+
+As an example, if the active low property for a dedicated GPIO is set, and the
+gpiod_set_(array)_value_xxx() passes "asserted" ("1"), the physical line level
+will be driven low.
+
+To summarize:
+
+Function (example) line property physical line
+gpiod_set_raw_value(desc, 0); don't care low
+gpiod_set_raw_value(desc, 1); don't care high
+gpiod_set_value(desc, 0); default (active high) low

+gpiod_set_value(desc, 1); open drain high impedance
+gpiod_set_value(desc, 0); open source high impedance
+gpiod_set_value(desc, 1); open source high
+
+It is possible to override these semantics using the *set_raw/'get_raw functions

+which should not need to care about the actual physical line level and worry about

+This driver implements support for Nuvoton W83773G temperature sensor
+chip. This chip implements one local and two remote sensors.
+The chip also features offsets for the two remote sensors which get added to
+the input readings. The chip does all the scaling by itself and the driver
+therefore reports true temperatures that don't need any user-space adjustments.
+Temperature is measured in degrees Celsius.
+The chip is wired over I2C/SMBus and specified over a temperature
+range of -40 to +125 degrees Celsius (for local sensor) and -40 to +127
+degrees Celsius (for remote sensors).
+Resolution for both the local and remote channels is 0.125 degree C.
+
+The chip supports only temperature measurement. The driver exports
+the temperature values via the following sysfs files:
+
+temp[1-3]_input
+temp[2-3]_fault
+temp[2-3]_offset

+=================
+Linux I2C and DMA
+=================
+
+Given that i2c is a low-speed bus, over which the majority of messages
+transferred are small, it is not considered a prime user of DMA access. At this
+time of writing, only 10% of I2C bus master drivers have DMA support
+implemented. And the vast majority of transactions are so small that setting up
+DMA for it will likely add more overhead than a plain PIO transfer.
+
+Therefore, it is *not* mandatory that the buffer of an I2C message is DMA safe.
+It does not seem reasonable to apply additional burdens when the feature is so
+rarely used. However, it is recommended to use a DMA-safe buffer if your
+message size is likely applicable for DMA. Most drivers have this threshold
+around 8 bytes (as of today, this is mostly an educated guess, however). For
+any message of 16 byte or larger, it is probably a really good idea. Please
+note that other subsystems you use might add requirements. E.g., if your
+I2C bus master driver is using USB as a bridge, then you need to have DMA
+safe buffers always, because USB requires it.
+
+Clients
+-------
+
+For clients, if you use a DMA safe buffer in i2c_msg, set the I2C_M_DMA_SAFE
+flag with it. Then, the I2C core and drivers know they can safely operate DMA
+on it. Note that using this flag is optional. I2C host drivers which are not
+updated to use this flag will work like before. And like before, they risk
+using an unsafe DMA buffer. To improve this situation, using I2C_M_DMA_SAFE in
+more and more clients and host drivers is the planned way forward. Note also
+that setting this flag makes only sense in kernel space. User space data is
+copied into kernel space anyhow. The I2C core makes sure the destination
+buffers in kernel space are always DMA capable. Also, when the core emulates
+SMBus transactions via I2C, the buffers for block transfers are DMA safe. Users
+of i2c_master_send() and i2c_master_recv() functions can now use DMA safe
+variants (i2c_master_send_dmasafe() and i2c_master_recv_dmasafe()) once they
+know their buffers are DMA safe. Users of i2c_transfer() must set the
+I2C_M_DMA_SAFE flag manually.
+
+Masters
+-------
+
+Bus master drivers wishing to implement safe DMA can use helper functions from
+the I2C core. One gives you a DMA-safe buffer for a given i2c_msg as long as a
+certain threshold is met::
+
+ dma_buf = i2c_get_dma_safe_msg_buf(msg, threshold_in_byte);
+
+If a buffer is returned, it is either msg->buf for the I2C_M_DMA_SAFE case or a
+bounce buffer. But you don't need to care about that detail, just use the
+returned buffer. If NULL is returned, the threshold was not met or a bounce
+buffer could not be allocated. Fall back to PIO in that case.
+
+In any case, a buffer obtained from above needs to be released. It ensures data
+is copied back to the message and a potentially used bounce buffer is freed::
+
+ i2c_release_dma_safe_msg_buf(msg, dma_buf);
+
+The bounce buffer handling from the core is generic and simple. It will always
+allocate a new bounce buffer. If you want a more sophisticated handling (e.g.
+reusing pre-allocated buffers), you are free to implement your own.
+
+Please also check the in-kernel documentation for details. The i2c-sh_mobile
+driver can be used as a reference example how to use the above helpers.
+
+Final note: If you plan to use DMA with I2C (or with anything else, actually)
+make sure you have CONFIG_DMA_API_DEBUG enabled during development. It can help
+you find various issues which can be complex to debug otherwise.

+Linux I2C fault injection
+=========================
+
+The GPIO based I2C bus master driver can be configured to provide fault
+injection capabilities. It is then meant to be connected to another I2C bus
+which is driven by the I2C bus master driver under test. The GPIO fault
+injection driver can create special states on the bus which the other I2C bus
+master driver should handle gracefully.
+
+Once the Kconfig option I2C_GPIO_FAULT_INJECTOR is enabled, there will be an
+'i2c-fault-injector' subdirectory in the Kernel debugfs filesystem, usually
+mounted at /sys/kernel/debug. There will be a separate subdirectory per GPIO
+driven I2C bus. Each subdirectory will contain files to trigger the fault
+injection. They will be described now along with their intended use-cases.
+
+"scl"
+-----
+
+By reading this file, you get the current state of SCL. By writing, you can
+change its state to either force it low or to release it again. So, by using
+"echo 0 > scl" you force SCL low and thus, no communication will be possible
+because the bus master under test will not be able to clock. It should detect
+the condition of SCL being unresponsive and report an error to the upper
+layers.
+
+"sda"
+-----
+
+By reading this file, you get the current state of SDA. By writing, you can
+change its state to either force it low or to release it again. So, by using
+"echo 0 > sda" you force SDA low and thus, data cannot be transmitted. The bus
+master under test should detect this condition and trigger a bus recovery (see
+I2C specification version 4, section 3.1.16) using the helpers of the Linux I2C
+core (see 'struct bus_recovery_info'). However, the bus recovery will not
+succeed because SDA is still pinned low until you manually release it again
+with "echo 1 > sda". A test with an automatic release can be done with the
+'incomplete_transfer' file.
+
+"incomplete_transfer"
+---------------------
+
+This file is write only and you need to write the address of an existing I2C
+client device to it. Then, a transfer to this device will be started, but it
+will stop at the ACK phase after the address of the client has been
+transmitted. Because the device will ACK its presence, this results in SDA
+being pulled low by the device while SCL is high. So, similar to the "sda" file
+above, the bus master under test should detect this condition and try a bus
+recovery. This time, however, it should succeed and the device should release
+SDA after toggling SCL. Please note: there are I2C client devices which detect
+a stuck SDA on their side and release it on their own after a few milliseconds.
+Also, there are external devices deglitching and monitoring the I2C bus. They
+can also detect a stuck SDA and will init a bus recovery on their own. If you
+want to implement bus recovery in a bus master driver, make sure you checked
+your hardware setup carefully before.

-Driver for tilt-switches connected via GPIOs
-============================================
-
-Generic driver to read data from tilt switches connected via gpios.
-Orientation can be provided by one or more than one tilt switches,
-i.e. each tilt switch providing one axis, and the number of axes
-is also not limited.
-
-
-Data structures
----------------
-
-The array of struct gpio in the gpios field is used to list the gpios
-that represent the current tilt state.
-
-The array of struct gpio_tilt_axis describes the axes that are reported
-to the input system. The values set therein are used for the
-input_set_abs_params calls needed to init the axes.
-
-The array of struct gpio_tilt_state maps gpio states to the corresponding
-values to report. The gpio state is represented as a bitfield where the
-bit-index corresponds to the index of the gpio in the struct gpio array.
-In the same manner the values stored in the axes array correspond to
-the elements of the gpio_tilt_axis-array.
-

-=====================
-
-How to format kernel-doc comments
----------------------------------
-
-In order to provide embedded, 'C' friendly, easy to maintain,
-but consistent and extractable documentation of the functions and
-data structures in the Linux kernel, the Linux kernel has adopted
-a consistent style for documenting functions and their parameters,
-and structures and their members.
-
-The format for this documentation is called the kernel-doc format.
-It is documented in this Documentation/kernel-doc-nano-HOWTO.txt file.
-
-This style embeds the documentation within the source files, using
-a few simple conventions. The scripts/kernel-doc perl script, the
-Documentation/sphinx/kerneldoc.py Sphinx extension and other tools understand
-these conventions, and are used to extract this embedded documentation
-into various documents.
-
-In order to provide good documentation of kernel functions and data
-structures, please use the following conventions to format your
-kernel-doc comments in Linux kernel source.
-
-We definitely need kernel-doc formatted documentation for functions
-that are exported to loadable modules using EXPORT_SYMBOL.
-
-We also look to provide kernel-doc formatted documentation for
-functions externally visible to other kernel files (not marked
-"static").
-
-We also recommend providing kernel-doc formatted documentation
-for private (file "static") routines, for consistency of kernel
-source code layout. But this is lower priority and at the
-discretion of the MAINTAINER of that kernel source file.
-
-Data structures visible in kernel include files should also be
-documented using kernel-doc formatted comments.
-
-The opening comment mark "/**" is reserved for kernel-doc comments.
-Only comments so marked will be considered by the kernel-doc scripts,
-and any comment so marked must be in kernel-doc format. Do not use
-"/**" to be begin a comment block unless the comment block contains
-kernel-doc formatted comments. The closing comment marker for
-kernel-doc comments can be either "*/" or "**/", but "*/" is
-preferred in the Linux kernel tree.
-
-Kernel-doc comments should be placed just before the function
-or data structure being described.
-
-Example kernel-doc function comment:
-
-/**
- * foobar() - short function description of foobar
- * @arg1: Describe the first argument to foobar.
- * @arg2: Describe the second argument to foobar.
- * One can provide multiple line descriptions
- * for arguments.
- *
- * A longer description, with more discussion of the function foobar()
- * that might be useful to those using or modifying it. Begins with
- * empty comment line, and may include additional embedded empty
- * comment lines.
- *
- * The longer description can have multiple paragraphs.
- *
- * Return: Describe the return value of foobar.
- */
-
-The short description following the subject can span multiple lines
-and ends with an @argument description, an empty line or the end of
-the comment block.
-
-The @argument descriptions must begin on the very next line following
-this opening short function description line, with no intervening
-empty comment lines.
-
-If a function parameter is "..." (varargs), it should be listed in
-kernel-doc notation as:
- * @...: description
-
-The return value, if any, should be described in a dedicated section
-named "Return".
-
-Example kernel-doc data structure comment.
-
-/**
- * struct blah - the basic blah structure
- * @mem1: describe the first member of struct blah
- * @mem2: describe the second member of struct blah,
- * perhaps with more lines and words.
- *
- * Longer description of this structure.
- */
-
-The kernel-doc function comments describe each parameter to the
-function, in order, with the @name lines.
-
-The kernel-doc data structure comments describe each structure member
-in the data structure, with the @name lines.
-
-The longer description formatting is "reflowed", losing your line
-breaks. So presenting carefully formatted lists within these
-descriptions won't work so well; derived documentation will lose
-the formatting.
-
-See the section below "How to add extractable documentation to your
-source files" for more details and notes on how to format kernel-doc
-comments.
-
-Components of the kernel-doc system
------------------------------------
-
-Many places in the source tree have extractable documentation in the
-form of block comments above functions. The components of this system
-are:
-
-- scripts/kernel-doc
-
- This is a perl script that hunts for the block comments and can mark
- them up directly into DocBook, ReST, man, text, and HTML. (No, not
- texinfo.)
-
-- scripts/docproc.c
-
- This is a program for converting SGML template files into SGML
- files. When a file is referenced it is searched for symbols
- exported (EXPORT_SYMBOL), to be able to distinguish between internal
- and external functions.
- It invokes kernel-doc, giving it the list of functions that
- are to be documented.
- Additionally it is used to scan the SGML template files to locate
- all the files referenced herein. This is used to generate dependency
- information as used by make.
-
-- Makefile
-
- The targets 'xmldocs', 'latexdocs', 'pdfdocs', 'epubdocs'and 'htmldocs'
- are used to build XML DocBook files, LaTeX files, PDF files,
- ePub files and html files in Documentation/.
-
-How to extract the documentation
---------------------------------
-
-If you just want to read the ready-made books on the various
-subsystems, just type 'make epubdocs', or 'make pdfdocs', or 'make htmldocs',
-depending on your preference. If you would rather read a different format,
-you can type 'make xmldocs' and then use DocBook tools to convert
-Documentation/output/*.xml to a format of your choice (for example,
-'db2html ...' if 'make htmldocs' was not defined).
-
-If you want to see man pages instead, you can do this:
-
-$ cd linux
-$ scripts/kernel-doc -man $(find -name '*.c') | split-man.pl /tmp/man
-$ scripts/kernel-doc -man $(find -name '*.h') | split-man.pl /tmp/man
-
-Here is split-man.pl:
-
--->
-#!/usr/bin/perl
-
-if ($#ARGV < 0) {

-How to add extractable documentation to your source files
----------------------------------------------------------
-
-The format of the block comment is like this:
-
-/**
- * function_name(:)? (- short description)?
-(* @parameterx(space)*: (description of parameter x)?)*
-(* a blank line)?
- * (Description:)? (Description of function)?
- * (section header: (section description)? )*
-(*)?*/
-
-All "description" text can span multiple lines, although the
-function_name & its short description are traditionally on a single line.
-Description text may also contain blank lines (i.e., lines that contain
-only a "*").
-
-"section header:" names must be unique per function (or struct,
-union, typedef, enum).
-
-Use the section header "Return" for sections describing the return value
-of a function.
-
-Avoid putting a spurious blank line after the function name, or else the
-description will be repeated!
-
-All descriptive text is further processed, scanning for the following special
-patterns, which are highlighted appropriately.
-
-'funcname()' - function
-'$ENVVAR' - environment variable
-'&struct_name' - name of a structure (up to two words including 'struct')
-'@parameter' - name of a parameter
-'%CONST' - name of a constant.
-
-NOTE 1: The multi-line descriptive text you provide does *not* recognize
-line breaks, so if you try to format some text nicely, as in:
-
- Return:
- 0 - cool
- 1 - invalid arg
- 2 - out of memory
-
-this will all run together and produce:
-
- Return: 0 - cool 1 - invalid arg 2 - out of memory
-
-NOTE 2: If the descriptive text you provide has lines that begin with
-some phrase followed by a colon, each of those phrases will be taken as
-a new section heading, which means you should similarly try to avoid text
-like:
-
- Return:
- 0: cool
- 1: invalid arg
- 2: out of memory
-
-every line of which would start a new section. Again, probably not
-what you were after.
-
-Take a look around the source tree for examples.
-
-
-kernel-doc for structs, unions, enums, and typedefs
----------------------------------------------------
-
-Beside functions you can also write documentation for structs, unions,
-enums and typedefs. Instead of the function name you must write the name
-of the declaration; the struct/union/enum/typedef must always precede
-the name. Nesting of declarations is not supported.
-Use the argument mechanism to document members or constants.
-
-Inside a struct description, you can use the "private:" and "public:"
-comment tags. Structure fields that are inside a "private:" area
-are not listed in the generated output documentation. The "private:"
-and "public:" tags must begin immediately following a "/*" comment
-marker. They may optionally include comments between the ":" and the
-ending "*/" marker.
-
-Example:
-
-/**
- * struct my_struct - short description
- * @a: first member
- * @b: second member
- *
- * Longer description
- */
-struct my_struct {
- int a;
- int b;
-/* private: internal use only */
- int c;
-};
-
-
-Including documentation blocks in source files
-----------------------------------------------
-
-To facilitate having source code and comments close together, you can
-include kernel-doc documentation blocks that are free-form comments
-instead of being kernel-doc for functions, structures, unions,
-enums, or typedefs. This could be used for something like a
-theory of operation for a driver or library code, for example.
-
-This is done by using a DOC: section keyword with a section title. E.g.:
-
-/**
- * DOC: Theory of Operation
- *
- * The whizbang foobar is a dilly of a gizmo. It can do whatever you
- * want it to do, at any time. It reads your mind. Here's how it works.
- *
- * foo bar splat
- *
- * The only drawback to this gizmo is that is can sometimes damage
- * hardware, software, or its subject(s).
- */
-
-DOC: sections are used in ReST files.

+Creating Pull Requests
+======================
+
+This chapter describes how maintainers can create and submit pull requests
+to other maintainers. This is useful for transferring changes from one
+maintainers tree to another maintainers tree.
+
+This document was written by Tobin C. Harding (who at that time, was not an
+experienced maintainer) primarily from comments made by Greg Kroah-Hartman
+and Linus Torvalds on LKML. Suggestions and fixes by Jonathan Corbet and
+Mauro Carvalho Chehab. Misrepresentation was unintentional but inevitable,
+please direct abuse to Tobin C. Harding <me@tobin.cc>.
+
+Original email thread::
+
+ http://lkml.kernel.org/r/20171114110500.GA21175@kroah.com
+
+
+Create Branch
+-------------
+
+To start with you will need to have all the changes you wish to include in
+the pull request on a separate branch. Typically you will base this branch
+off of a branch in the developers tree whom you intend to send the pull
+request to.
+
+In order to create the pull request you must first tag the branch that you
+have just created. It is recommended that you choose a meaningful tag name,
+in a way that you and others can understand, even after some time. A good
+practice is to include in the name an indicator of the sybsystem of origin
+and the target kernel version.
+
+Greg offers the following. A pull request with miscellaneous stuff for
+drivers/char, to be applied at the Kernel version 4.15-rc1 could be named
+as ``char-misc-4.15-rc1``. If such tag would be produced from a branch
+named ``char-misc-next``, you would be using the following command::
+
+ git tag -s char-misc-4.15-rc1 char-misc-next
+
+that will create a signed tag called ``char-misc-4.15-rc1`` based on the
+last commit in the ``char-misc-next`` branch, and sign it with your gpg key
+(see :ref:`Documentation/maintainer/configure_git.rst <configuregit>`).
+
+Linus will only accept pull requests based on a signed tag. Other
+maintainers may differ.
+
+When you run the above command ``git`` will drop you into an editor and ask
+you to describe the tag. In this case, you are describing a pull request,
+so outline what is contained here, why it should be merged, and what, if
+any, testing has been done. All of this information will end up in the tag
+itself, and then in the merge commit that the maintainer makes if/when they
+merge the pull request. So write it up well, as it will be in the kernel
+tree for forever.
+
+As said by Linus::
+
+ Anyway, at least to me, the important part is the *message*. I want
+ to understand what I'm pulling, and why I should pull it. I also
+ want to use that message as the message for the merge, so it should
+ not just make sense to me, but make sense as a historical record
+ too.
+
+ Note that if there is something odd about the pull request, that
+ should very much be in the explanation. If you're touching files
+ that you don't maintain, explain _why_. I will see it in the
+ diffstat anyway, and if you didn't mention it, I'll just be extra
+ suspicious. And when you send me new stuff after the merge window
+ (or even bug-fixes, but ones that look scary), explain not just
+ what they do and why they do it, but explain the _timing_. What
+ happened that this didn't go through the merge window..
+
+ I will take both what you write in the email pull request _and_ in
+ the signed tag, so depending on your workflow, you can either
+ describe your work in the signed tag (which will also automatically
+ make it into the pull request email), or you can make the signed
+ tag just a placeholder with nothing interesting in it, and describe
+ the work later when you actually send me the pull request.
+
+ And yes, I will edit the message. Partly because I tend to do just
+ trivial formatting (the whole indentation and quoting etc), but
+ partly because part of the message may make sense for me at pull
+ time (describing the conflicts and your personal issues for sending
+ it right now), but may not make sense in the context of a merge
+ commit message, so I will try to make it all make sense. I will
+ also fix any speeling mistaeks and bad grammar I notice,
+ particularly for non-native speakers (but also for native ones
+ ;^). But I may miss some, or even add some.
+
+ Linus
+
+Greg gives, as an example pull request::
+
+ Char/Misc patches for 4.15-rc1
+
+ Here is the big char/misc patch set for the 4.15-rc1 merge window.
+ Contained in here is the normal set of new functions added to all
+ of these crazy drivers, as well as the following brand new
+ subsystems:
+ - time_travel_controller: Finally a set of drivers for the
+ latest time travel bus architecture that provides i/o to
+ the CPU before it asked for it, allowing uninterrupted
+ processing
+ - relativity_shifters: due to the affect that the
+ time_travel_controllers have on the overall system, there
+ was a need for a new set of relativity shifter drivers to
+ accommodate the newly formed black holes that would
+ threaten to suck CPUs into them. This subsystem handles
+ this in a way to successfully neutralize the problems.
+ There is a Kconfig option to force these to be enabled
+ when needed, so problems should not occur.
+
+ All of these patches have been successfully tested in the latest
+ linux-next releases, and the original problems that it found have
+ all been resolved (apologies to anyone living near Canberra for the
+ lack of the Kconfig options in the earlier versions of the
+ linux-next tree creations.)
+
+ Signed-off-by: Your-name-here <your_email@domain>
+
+
+The tag message format is just like a git commit id. One line at the top
+for a "summary subject" and be sure to sign-off at the bottom.
+
+Now that you have a local signed tag, you need to push it up to where it
+can be retrieved::
+
+ git push origin char-misc-4.15-rc1
+
+
+Create Pull Request
+-------------------
+
+The last thing to do is create the pull request message. ``git`` handily
+will do this for you with the ``git request-pull`` command, but it needs a
+bit of help determining what you want to pull, and on what to base the pull
+against (to show the correct changes to be pulled and the diffstat). The
+following command(s) will generate a pull request::
+
+ git request-pull master git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git/ char-misc-4.15-rc1
+
+Quoting Greg::
+
+ This is asking git to compare the difference from the
+ 'char-misc-4.15-rc1' tag location, to the head of the 'master'
+ branch (which in my case points to the last location in Linus's
+ tree that I diverged from, usually a -rc release) and to use the
+ git:// protocol to pull from. If you wish to use https://, that
+ can be used here instead as well (but note that some people behind
+ firewalls will have problems with https git pulls).
+
+ If the char-misc-4.15-rc1 tag is not present in the repo that I am
+ asking to be pulled from, git will complain saying it is not there,
+ a handy way to remember to actually push it to a public location.
+
+ The output of 'git request-pull' will contain the location of the
+ git tree and specific tag to pull from, and the full text
+ description of that tag (which is why you need to provide good
+ information in that tag). It will also create a diffstat of the
+ pull request, and a shortlog of the individual commits that the
+ pull request will provide.
+
+Linus responded that he tends to prefer the ``git://`` protocol. Other
+maintainers may have different preferences. Also, note that if you are
+creating pull requests without a signed tag then ``https://`` may be a
+better choice. Please see the original thread for the full discussion.
+
+
+Submit Pull Request
+-------------------
+
+A pull request is submitted in the same way as an ordinary patch. Send as
+inline email to the maintainer and CC LKML and any sub-system specific
+lists if required. Pull requests to Linus typically have a subject line
+something like::
+
+ [GIT PULL] <subsystem> changes for v4.15-rc1

+SocketCAN - Controller Area Network
+===================================
+
+Overview / What is SocketCAN
+============================
+
+The socketcan package is an implementation of CAN protocols
+(Controller Area Network) for Linux. CAN is a networking technology
+which has widespread use in automation, embedded devices, and
+automotive fields. While there have been other CAN implementations
+for Linux based on character devices, SocketCAN uses the Berkeley
+socket API, the Linux network stack and implements the CAN device
+drivers as network interfaces. The CAN socket API has been designed
+as similar as possible to the TCP/IP protocols to allow programmers,
+familiar with network programming, to easily learn how to use CAN
+sockets.
+
+
+.. _socketcan-motivation:
+
+Motivation / Why Using the Socket API
+=====================================
+
+There have been CAN implementations for Linux before SocketCAN so the
+question arises, why we have started another project. Most existing
+implementations come as a device driver for some CAN hardware, they
+are based on character devices and provide comparatively little
+functionality. Usually, there is only a hardware-specific device
+driver which provides a character device interface to send and
+receive raw CAN frames, directly to/from the controller hardware.
+Queueing of frames and higher-level transport protocols like ISO-TP
+have to be implemented in user space applications. Also, most
+character-device implementations support only one single process to
+open the device at a time, similar to a serial interface. Exchanging
+the CAN controller requires employment of another device driver and
+often the need for adaption of large parts of the application to the
+new driver's API.
+
+SocketCAN was designed to overcome all of these limitations. A new
+protocol family has been implemented which provides a socket interface
+to user space applications and which builds upon the Linux network
+layer, enabling use all of the provided queueing functionality. A device
+driver for CAN controller hardware registers itself with the Linux
+network layer as a network device, so that CAN frames from the
+controller can be passed up to the network layer and on to the CAN
+protocol family module and also vice-versa. Also, the protocol family
+module provides an API for transport protocol modules to register, so
+that any number of transport protocols can be loaded or unloaded
+dynamically. In fact, the can core module alone does not provide any
+protocol and cannot be used without loading at least one additional
+protocol module. Multiple sockets can be opened at the same time,
+on different or the same protocol module and they can listen/send
+frames on different or the same CAN IDs. Several sockets listening on
+the same interface for frames with the same CAN ID are all passed the
+same received matching CAN frames. An application wishing to
+communicate using a specific transport protocol, e.g. ISO-TP, just
+selects that protocol when opening the socket, and then can read and
+write application data byte streams, without having to deal with
+CAN-IDs, frames, etc.
+
+Similar functionality visible from user-space could be provided by a
+character device, too, but this would lead to a technically inelegant
+solution for a couple of reasons:
+
+* **Intricate usage:** Instead of passing a protocol argument to
+ socket(2) and using bind(2) to select a CAN interface and CAN ID, an
+ application would have to do all these operations using ioctl(2)s.
+
+* **Code duplication:** A character device cannot make use of the Linux
+ network queueing code, so all that code would have to be duplicated
+ for CAN networking.
+
+* **Abstraction:** In most existing character-device implementations, the
+ hardware-specific device driver for a CAN controller directly
+ provides the character device for the application to work with.
+ This is at least very unusual in Unix systems for both, char and
+ block devices. For example you don't have a character device for a
+ certain UART of a serial interface, a certain sound chip in your
+ computer, a SCSI or IDE controller providing access to your hard
+ disk or tape streamer device. Instead, you have abstraction layers
+ which provide a unified character or block device interface to the
+ application on the one hand, and a interface for hardware-specific
+ device drivers on the other hand. These abstractions are provided
+ by subsystems like the tty layer, the audio subsystem or the SCSI
+ and IDE subsystems for the devices mentioned above.
+
+ The easiest way to implement a CAN device driver is as a character
+ device without such a (complete) abstraction layer, as is done by most
+ existing drivers. The right way, however, would be to add such a
+ layer with all the functionality like registering for certain CAN
+ IDs, supporting several open file descriptors and (de)multiplexing
+ CAN frames between them, (sophisticated) queueing of CAN frames, and
+ providing an API for device drivers to register with. However, then
+ it would be no more difficult, or may be even easier, to use the
+ networking framework provided by the Linux kernel, and this is what
+ SocketCAN does.
+
+The use of the networking framework of the Linux kernel is just the
+natural and most appropriate way to implement CAN for Linux.
+
+
+.. _socketcan-concept:
+
+SocketCAN Concept
+=================
+
+As described in :ref:`socketcan-motivation` the main goal of SocketCAN is to
+provide a socket interface to user space applications which builds
+upon the Linux network layer. In contrast to the commonly known
+TCP/IP and ethernet networking, the CAN bus is a broadcast-only(!)
+medium that has no MAC-layer addressing like ethernet. The CAN-identifier
+(can_id) is used for arbitration on the CAN-bus. Therefore the CAN-IDs
+have to be chosen uniquely on the bus. When designing a CAN-ECU
+network the CAN-IDs are mapped to be sent by a specific ECU.
+For this reason a CAN-ID can be treated best as a kind of source address.
+
+
+.. _socketcan-receive-lists:
+
+Receive Lists
+-------------
+
+The network transparent access of multiple applications leads to the
+problem that different applications may be interested in the same
+CAN-IDs from the same CAN network interface. The SocketCAN core
+module - which implements the protocol family CAN - provides several
+high efficient receive lists for this reason. If e.g. a user space
+application opens a CAN RAW socket, the raw protocol module itself
+requests the (range of) CAN-IDs from the SocketCAN core that are
+requested by the user. The subscription and unsubscription of
+CAN-IDs can be done for specific CAN interfaces or for all(!) known
+CAN interfaces with the can_rx_(un)register() functions provided to
+CAN protocol modules by the SocketCAN core (see :ref:`socketcan-core-module`).
+To optimize the CPU usage at runtime the receive lists are split up
+into several specific lists per device that match the requested
+filter complexity for a given use-case.
+
+
+.. _socketcan-local-loopback1:
+
+Local Loopback of Sent Frames
+-----------------------------
+
+As known from other networking concepts the data exchanging
+applications may run on the same or different nodes without any
+change (except for the according addressing information):
+
+.. code::
+
+ ___ ___ ___ _______ ___
+ | _ | | _ | | _ | | _ _ | | _ |
+ ||A|| ||B|| ||C|| ||A| |B|| ||C||
+ |___| |___| |___| |_______| |___|
+ | | | | |
+ -----------------(1)- CAN bus -(2)---------------
+
+To ensure that application A receives the same information in the
+example (2) as it would receive in example (1) there is need for
+some kind of local loopback of the sent CAN frames on the appropriate
+node.
+
+The Linux network devices (by default) just can handle the
+transmission and reception of media dependent frames. Due to the
+arbitration on the CAN bus the transmission of a low prio CAN-ID
+may be delayed by the reception of a high prio CAN frame. To
+reflect the correct [*]_ traffic on the node the loopback of the sent
+data has to be performed right after a successful transmission. If
+the CAN network interface is not capable of performing the loopback for
+some reason the SocketCAN core can do this task as a fallback solution.
+See :ref:`socketcan-local-loopback1` for details (recommended).
+
+The loopback functionality is enabled by default to reflect standard
+networking behaviour for CAN applications. Due to some requests from
+the RT-SocketCAN group the loopback optionally may be disabled for each
+separate socket. See sockopts from the CAN RAW sockets in :ref:`socketcan-raw-sockets`.
+
+.. [*] you really like to have this when you're running analyser
+ tools like 'candump' or 'cansniffer' on the (same) node.
+
+
+.. _socketcan-network-problem-notifications:
+
+Network Problem Notifications
+-----------------------------
+
+The use of the CAN bus may lead to several problems on the physical
+and media access control layer. Detecting and logging of these lower
+layer problems is a vital requirement for CAN users to identify
+hardware issues on the physical transceiver layer as well as
+arbitration problems and error frames caused by the different
+ECUs. The occurrence of detected errors are important for diagnosis
+and have to be logged together with the exact timestamp. For this
+reason the CAN interface driver can generate so called Error Message
+Frames that can optionally be passed to the user application in the
+same way as other CAN frames. Whenever an error on the physical layer
+or the MAC layer is detected (e.g. by the CAN controller) the driver
+creates an appropriate error message frame. Error messages frames can
+be requested by the user application using the common CAN filter
+mechanisms. Inside this filter definition the (interested) type of
+errors may be selected. The reception of error messages is disabled
+by default. The format of the CAN error message frame is briefly
+described in the Linux header file "include/uapi/linux/can/error.h".
+
+
+How to use SocketCAN
+====================
+
+Like TCP/IP, you first need to open a socket for communicating over a
+CAN network. Since SocketCAN implements a new protocol family, you
+need to pass PF_CAN as the first argument to the socket(2) system
+call. Currently, there are two CAN protocols to choose from, the raw
+socket protocol and the broadcast manager (BCM). So to open a socket,
+you would write::
+
+ s = socket(PF_CAN, SOCK_RAW, CAN_RAW);
+
+and::
+
+ s = socket(PF_CAN, SOCK_DGRAM, CAN_BCM);
+
+respectively. After the successful creation of the socket, you would
+normally use the bind(2) system call to bind the socket to a CAN
+interface (which is different from TCP/IP due to different addressing
+- see :ref:`socketcan-concept`). After binding (CAN_RAW) or connecting (CAN_BCM)
+the socket, you can read(2) and write(2) from/to the socket or use
+send(2), sendto(2), sendmsg(2) and the recv* counterpart operations
+on the socket as usual. There are also CAN specific socket options
+described below.
+
+The basic CAN frame structure and the sockaddr structure are defined
+in include/linux/can.h:
+
+.. code-block:: C
+
+ struct can_frame {
+ canid_t can_id; /* 32 bit CAN_ID + EFF/RTR/ERR flags */
+ __u8 can_dlc; /* frame payload length in byte (0 .. 8) */
+ __u8 __pad; /* padding */
+ __u8 __res0; /* reserved / padding */
+ __u8 __res1; /* reserved / padding */
+ __u8 data[8] __attribute__((aligned(8)));
+ };
+
+The alignment of the (linear) payload data[] to a 64bit boundary
+allows the user to define their own structs and unions to easily access
+the CAN payload. There is no given byteorder on the CAN bus by
+default. A read(2) system call on a CAN_RAW socket transfers a
+struct can_frame to the user space.
+
+The sockaddr_can structure has an interface index like the
+PF_PACKET socket, that also binds to a specific interface:
+
+.. code-block:: C
+
+ struct sockaddr_can {
+ sa_family_t can_family;
+ int can_ifindex;
+ union {
+ /* transport protocol class address info (e.g. ISOTP) */
+ struct { canid_t rx_id, tx_id; } tp;
+
+ /* reserved for future CAN protocols address information */
+ } can_addr;
+ };
+
+To determine the interface index an appropriate ioctl() has to
+be used (example for CAN_RAW sockets without error checking):
+
+.. code-block:: C
+
+ int s;
+ struct sockaddr_can addr;
+ struct ifreq ifr;
+
+ s = socket(PF_CAN, SOCK_RAW, CAN_RAW);
+
+ strcpy(ifr.ifr_name, "can0" );
+ ioctl(s, SIOCGIFINDEX, &ifr);
+
+ addr.can_family = AF_CAN;
+ addr.can_ifindex = ifr.ifr_ifindex;
+
+ bind(s, (struct sockaddr *)&addr, sizeof(addr));
+
+ (..)
+
+To bind a socket to all(!) CAN interfaces the interface index must
+be 0 (zero). In this case the socket receives CAN frames from every
+enabled CAN interface. To determine the originating CAN interface
+the system call recvfrom(2) may be used instead of read(2). To send
+on a socket that is bound to 'any' interface sendto(2) is needed to
+specify the outgoing interface.
+
+Reading CAN frames from a bound CAN_RAW socket (see above) consists
+of reading a struct can_frame:
+
+.. code-block:: C
+
+ struct can_frame frame;
+
+ nbytes = read(s, &frame, sizeof(struct can_frame));
+
+ if (nbytes < 0) {
+ perror("can raw socket read");
+ return 1;
+ }
+
+ /* paranoid check ... */
+ if (nbytes < sizeof(struct can_frame)) {
+ fprintf(stderr, "read: incomplete CAN frame\n");
+ return 1;
+ }
+
+ /* do something with the received CAN frame */
+
+Writing CAN frames can be done similarly, with the write(2) system call::
+
+ nbytes = write(s, &frame, sizeof(struct can_frame));
+
+When the CAN interface is bound to 'any' existing CAN interface
+(addr.can_ifindex = 0) it is recommended to use recvfrom(2) if the
+information about the originating CAN interface is needed:
+
+.. code-block:: C
+
+ struct sockaddr_can addr;
+ struct ifreq ifr;
+ socklen_t len = sizeof(addr);
+ struct can_frame frame;
+
+ nbytes = recvfrom(s, &frame, sizeof(struct can_frame),
+ 0, (struct sockaddr*)&addr, &len);
+
+ /* get interface name of the received CAN frame */
+ ifr.ifr_ifindex = addr.can_ifindex;
+ ioctl(s, SIOCGIFNAME, &ifr);
+ printf("Received a CAN frame from interface %s", ifr.ifr_name);
+
+To write CAN frames on sockets bound to 'any' CAN interface the
+outgoing interface has to be defined certainly:
+
+.. code-block:: C
+
+ strcpy(ifr.ifr_name, "can0");
+ ioctl(s, SIOCGIFINDEX, &ifr);
+ addr.can_ifindex = ifr.ifr_ifindex;
+ addr.can_family = AF_CAN;
+
+ nbytes = sendto(s, &frame, sizeof(struct can_frame),
+ 0, (struct sockaddr*)&addr, sizeof(addr));
+
+An accurate timestamp can be obtained with an ioctl(2) call after reading
+a message from the socket:
+
+.. code-block:: C
+
+ struct timeval tv;
+ ioctl(s, SIOCGSTAMP, &tv);
+
+The timestamp has a resolution of one microsecond and is set automatically
+at the reception of a CAN frame.
+
+Remark about CAN FD (flexible data rate) support:
+
+Generally the handling of CAN FD is very similar to the formerly described
+examples. The new CAN FD capable CAN controllers support two different
+bitrates for the arbitration phase and the payload phase of the CAN FD frame
+and up to 64 bytes of payload. This extended payload length breaks all the
+kernel interfaces (ABI) which heavily rely on the CAN frame with fixed eight
+bytes of payload (struct can_frame) like the CAN_RAW socket. Therefore e.g.
+the CAN_RAW socket supports a new socket option CAN_RAW_FD_FRAMES that
+switches the socket into a mode that allows the handling of CAN FD frames
+and (legacy) CAN frames simultaneously (see :ref:`socketcan-rawfd`).
+
+The struct canfd_frame is defined in include/linux/can.h:
+
+.. code-block:: C
+
+ struct canfd_frame {
+ canid_t can_id; /* 32 bit CAN_ID + EFF/RTR/ERR flags */
+ __u8 len; /* frame payload length in byte (0 .. 64) */
+ __u8 flags; /* additional flags for CAN FD */
+ __u8 __res0; /* reserved / padding */
+ __u8 __res1; /* reserved / padding */
+ __u8 data[64] __attribute__((aligned(8)));
+ };
+
+The struct canfd_frame and the existing struct can_frame have the can_id,
+the payload length and the payload data at the same offset inside their
+structures. This allows to handle the different structures very similar.
+When the content of a struct can_frame is copied into a struct canfd_frame
+all structure elements can be used as-is - only the data[] becomes extended.
+
+When introducing the struct canfd_frame it turned out that the data length
+code (DLC) of the struct can_frame was used as a length information as the
+length and the DLC has a 1:1 mapping in the range of 0 .. 8. To preserve
+the easy handling of the length information the canfd_frame.len element
+contains a plain length value from 0 .. 64. So both canfd_frame.len and
+can_frame.can_dlc are equal and contain a length information and no DLC.
+For details about the distinction of CAN and CAN FD capable devices and
+the mapping to the bus-relevant data length code (DLC), see :ref:`socketcan-can-fd-driver`.
+
+The length of the two CAN(FD) frame structures define the maximum transfer
+unit (MTU) of the CAN(FD) network interface and skbuff data length. Two
+definitions are specified for CAN specific MTUs in include/linux/can.h:
+
+.. code-block:: C
+
+ #define CAN_MTU (sizeof(struct can_frame)) == 16 => 'legacy' CAN frame
+ #define CANFD_MTU (sizeof(struct canfd_frame)) == 72 => CAN FD frame
+
+
+.. _socketcan-raw-sockets:
+
+RAW Protocol Sockets with can_filters (SOCK_RAW)
+------------------------------------------------
+
+Using CAN_RAW sockets is extensively comparable to the commonly
+known access to CAN character devices. To meet the new possibilities
+provided by the multi user SocketCAN approach, some reasonable
+defaults are set at RAW socket binding time:
+
+- The filters are set to exactly one filter receiving everything
+- The socket only receives valid data frames (=> no error message frames)
+- The loopback of sent CAN frames is enabled (see :ref:`socketcan-local-loopback2`)
+- The socket does not receive its own sent frames (in loopback mode)
+
+These default settings may be changed before or after binding the socket.
+To use the referenced definitions of the socket options for CAN_RAW
+sockets, include <linux/can/raw.h>.
+
+
+.. _socketcan-rawfilter:
+
+RAW socket option CAN_RAW_FILTER
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The reception of CAN frames using CAN_RAW sockets can be controlled
+by defining 0 .. n filters with the CAN_RAW_FILTER socket option.
+
+The CAN filter structure is defined in include/linux/can.h:
+
+.. code-block:: C
+
+ struct can_filter {
+ canid_t can_id;
+ canid_t can_mask;
+ };
+
+A filter matches, when:
+
+.. code-block:: C
+
+ <received_can_id> & mask == can_id & mask
+
+which is analogous to known CAN controllers hardware filter semantics.
+The filter can be inverted in this semantic, when the CAN_INV_FILTER
+bit is set in can_id element of the can_filter structure. In
+contrast to CAN controller hardware filters the user may set 0 .. n
+receive filters for each open socket separately:
+
+.. code-block:: C
+
+ struct can_filter rfilter[2];
+
+ rfilter[0].can_id = 0x123;
+ rfilter[0].can_mask = CAN_SFF_MASK;
+ rfilter[1].can_id = 0x200;
+ rfilter[1].can_mask = 0x700;
+
+ setsockopt(s, SOL_CAN_RAW, CAN_RAW_FILTER, &rfilter, sizeof(rfilter));
+
+To disable the reception of CAN frames on the selected CAN_RAW socket:
+
+.. code-block:: C
+
+ setsockopt(s, SOL_CAN_RAW, CAN_RAW_FILTER, NULL, 0);
+
+To set the filters to zero filters is quite obsolete as to not read
+data causes the raw socket to discard the received CAN frames. But
+having this 'send only' use-case we may remove the receive list in the
+Kernel to save a little (really a very little!) CPU usage.
+
+CAN Filter Usage Optimisation
+.............................
+
+The CAN filters are processed in per-device filter lists at CAN frame
+reception time. To reduce the number of checks that need to be performed
+while walking through the filter lists the CAN core provides an optimized
+filter handling when the filter subscription focusses on a single CAN ID.
+
+For the possible 2048 SFF CAN identifiers the identifier is used as an index
+to access the corresponding subscription list without any further checks.
+For the 2^29 possible EFF CAN identifiers a 10 bit XOR folding is used as
+hash function to retrieve the EFF table index.
+
+To benefit from the optimized filters for single CAN identifiers the
+CAN_SFF_MASK or CAN_EFF_MASK have to be set into can_filter.mask together
+with set CAN_EFF_FLAG and CAN_RTR_FLAG bits. A set CAN_EFF_FLAG bit in the
+can_filter.mask makes clear that it matters whether a SFF or EFF CAN ID is
+subscribed. E.g. in the example from above:
+
+.. code-block:: C
+
+ rfilter[0].can_id = 0x123;
+ rfilter[0].can_mask = CAN_SFF_MASK;
+
+both SFF frames with CAN ID 0x123 and EFF frames with 0xXXXXX123 can pass.
+
+To filter for only 0x123 (SFF) and 0x12345678 (EFF) CAN identifiers the
+filter has to be defined in this way to benefit from the optimized filters:
+
+.. code-block:: C
+
+ struct can_filter rfilter[2];
+
+ rfilter[0].can_id = 0x123;
+ rfilter[0].can_mask = (CAN_EFF_FLAG | CAN_RTR_FLAG | CAN_SFF_MASK);
+ rfilter[1].can_id = 0x12345678 | CAN_EFF_FLAG;
+ rfilter[1].can_mask = (CAN_EFF_FLAG | CAN_RTR_FLAG | CAN_EFF_MASK);
+
+ setsockopt(s, SOL_CAN_RAW, CAN_RAW_FILTER, &rfilter, sizeof(rfilter));
+
+
+RAW Socket Option CAN_RAW_ERR_FILTER
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As described in :ref:`socketcan-network-problem-notifications` the CAN interface driver can generate so
+called Error Message Frames that can optionally be passed to the user
+application in the same way as other CAN frames. The possible
+errors are divided into different error classes that may be filtered
+using the appropriate error mask. To register for every possible
+error condition CAN_ERR_MASK can be used as value for the error mask.
+The values for the error mask are defined in linux/can/error.h:
+
+.. code-block:: C
+
+ can_err_mask_t err_mask = ( CAN_ERR_TX_TIMEOUT | CAN_ERR_BUSOFF );
+
+ setsockopt(s, SOL_CAN_RAW, CAN_RAW_ERR_FILTER,
+ &err_mask, sizeof(err_mask));
+
+
+RAW Socket Option CAN_RAW_LOOPBACK
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To meet multi user needs the local loopback is enabled by default
+(see :ref:`socketcan-local-loopback1` for details). But in some embedded use-cases
+(e.g. when only one application uses the CAN bus) this loopback
+functionality can be disabled (separately for each socket):
+
+.. code-block:: C
+
+ int loopback = 0; /* 0 = disabled, 1 = enabled (default) */
+
+ setsockopt(s, SOL_CAN_RAW, CAN_RAW_LOOPBACK, &loopback, sizeof(loopback));
+
+
+RAW socket option CAN_RAW_RECV_OWN_MSGS
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When the local loopback is enabled, all the sent CAN frames are
+looped back to the open CAN sockets that registered for the CAN
+frames' CAN-ID on this given interface to meet the multi user
+needs. The reception of the CAN frames on the same socket that was
+sending the CAN frame is assumed to be unwanted and therefore
+disabled by default. This default behaviour may be changed on
+demand:
+
+.. code-block:: C
+
+ int recv_own_msgs = 1; /* 0 = disabled (default), 1 = enabled */
+
+ setsockopt(s, SOL_CAN_RAW, CAN_RAW_RECV_OWN_MSGS,
+ &recv_own_msgs, sizeof(recv_own_msgs));
+
+
+.. _socketcan-rawfd:
+
+RAW Socket Option CAN_RAW_FD_FRAMES
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+CAN FD support in CAN_RAW sockets can be enabled with a new socket option
+CAN_RAW_FD_FRAMES which is off by default. When the new socket option is
+not supported by the CAN_RAW socket (e.g. on older kernels), switching the
+CAN_RAW_FD_FRAMES option returns the error -ENOPROTOOPT.
+
+Once CAN_RAW_FD_FRAMES is enabled the application can send both CAN frames
+and CAN FD frames. OTOH the application has to handle CAN and CAN FD frames
+when reading from the socket:
+
+.. code-block:: C
+
+ CAN_RAW_FD_FRAMES enabled: CAN_MTU and CANFD_MTU are allowed
+ CAN_RAW_FD_FRAMES disabled: only CAN_MTU is allowed (default)
+
+Example:
+
+.. code-block:: C
+
+ [ remember: CANFD_MTU == sizeof(struct canfd_frame) ]
+
+ struct canfd_frame cfd;
+
+ nbytes = read(s, &cfd, CANFD_MTU);
+
+ if (nbytes == CANFD_MTU) {
+ printf("got CAN FD frame with length %d\n", cfd.len);
+ /* cfd.flags contains valid data */
+ } else if (nbytes == CAN_MTU) {
+ printf("got legacy CAN frame with length %d\n", cfd.len);
+ /* cfd.flags is undefined */
+ } else {
+ fprintf(stderr, "read: invalid CAN(FD) frame\n");
+ return 1;
+ }
+
+ /* the content can be handled independently from the received MTU size */
+
+ printf("can_id: %X data length: %d data: ", cfd.can_id, cfd.len);
+ for (i = 0; i < cfd.len; i++)
+ printf("%02X ", cfd.data[i]);
+
+When reading with size CANFD_MTU only returns CAN_MTU bytes that have
+been received from the socket a legacy CAN frame has been read into the
+provided CAN FD structure. Note that the canfd_frame.flags data field is
+not specified in the struct can_frame and therefore it is only valid in
+CANFD_MTU sized CAN FD frames.
+
+Implementation hint for new CAN applications:
+
+To build a CAN FD aware application use struct canfd_frame as basic CAN
+data structure for CAN_RAW based applications. When the application is
+executed on an older Linux kernel and switching the CAN_RAW_FD_FRAMES
+socket option returns an error: No problem. You'll get legacy CAN frames
+or CAN FD frames and can process them the same way.
+
+When sending to CAN devices make sure that the device is capable to handle
+CAN FD frames by checking if the device maximum transfer unit is CANFD_MTU.
+The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.
+
+
+RAW socket option CAN_RAW_JOIN_FILTERS
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The CAN_RAW socket can set multiple CAN identifier specific filters that
+lead to multiple filters in the af_can.c filter processing. These filters
+are indenpendent from each other which leads to logical OR'ed filters when
+applied (see :ref:`socketcan-rawfilter`).
+
+This socket option joines the given CAN filters in the way that only CAN
+frames are passed to user space that matched *all* given CAN filters. The
+semantic for the applied filters is therefore changed to a logical AND.
+
+This is useful especially when the filterset is a combination of filters
+where the CAN_INV_FILTER flag is set in order to notch single CAN IDs or
+CAN ID ranges from the incoming traffic.
+
+
+RAW Socket Returned Message Flags
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When using recvmsg() call, the msg->msg_flags may contain following flags:
+
+MSG_DONTROUTE:
+ set when the received frame was created on the local host.
+
+MSG_CONFIRM:
+ set when the frame was sent via the socket it is received on.
+ This flag can be interpreted as a 'transmission confirmation' when the
+ CAN driver supports the echo of frames on driver level, see
+ :ref:`socketcan-local-loopback1` and :ref:`socketcan-local-loopback2`.
+ In order to receive such messages, CAN_RAW_RECV_OWN_MSGS must be set.
+
+
+Broadcast Manager Protocol Sockets (SOCK_DGRAM)
+-----------------------------------------------
+
+The Broadcast Manager protocol provides a command based configuration
+interface to filter and send (e.g. cyclic) CAN messages in kernel space.
+
+Receive filters can be used to down sample frequent messages; detect events
+such as message contents changes, packet length changes, and do time-out
+monitoring of received messages.
+
+Periodic transmission tasks of CAN frames or a sequence of CAN frames can be
+created and modified at runtime; both the message content and the two
+possible transmit intervals can be altered.
+
+A BCM socket is not intended for sending individual CAN frames using the
+struct can_frame as known from the CAN_RAW socket. Instead a special BCM
+configuration message is defined. The basic BCM configuration message used
+to communicate with the broadcast manager and the available operations are
+defined in the linux/can/bcm.h include. The BCM message consists of a
+message header with a command ('opcode') followed by zero or more CAN frames.
+The broadcast manager sends responses to user space in the same form:
+
+.. code-block:: C
+
+ struct bcm_msg_head {
+ __u32 opcode; /* command */
+ __u32 flags; /* special flags */
+ __u32 count; /* run 'count' times with ival1 */
+ struct timeval ival1, ival2; /* count and subsequent interval */
+ canid_t can_id; /* unique can_id for task */
+ __u32 nframes; /* number of can_frames following */
+ struct can_frame frames[0];
+ };
+
+The aligned payload 'frames' uses the same basic CAN frame structure defined
+at the beginning of :ref:`socketcan-rawfd` and in the include/linux/can.h include. All
+messages to the broadcast manager from user space have this structure.
+
+Note a CAN_BCM socket must be connected instead of bound after socket
+creation (example without error checking):
+
+.. code-block:: C
+
+ int s;
+ struct sockaddr_can addr;
+ struct ifreq ifr;
+
+ s = socket(PF_CAN, SOCK_DGRAM, CAN_BCM);
+
+ strcpy(ifr.ifr_name, "can0");
+ ioctl(s, SIOCGIFINDEX, &ifr);
+
+ addr.can_family = AF_CAN;
+ addr.can_ifindex = ifr.ifr_ifindex;
+
+ connect(s, (struct sockaddr *)&addr, sizeof(addr));
+
+ (..)
+
+The broadcast manager socket is able to handle any number of in flight
+transmissions or receive filters concurrently. The different RX/TX jobs are
+distinguished by the unique can_id in each BCM message. However additional
+CAN_BCM sockets are recommended to communicate on multiple CAN interfaces.
+When the broadcast manager socket is bound to 'any' CAN interface (=> the
+interface index is set to zero) the configured receive filters apply to any
+CAN interface unless the sendto() syscall is used to overrule the 'any' CAN
+interface index. When using recvfrom() instead of read() to retrieve BCM
+socket messages the originating CAN interface is provided in can_ifindex.
+
+
+Broadcast Manager Operations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The opcode defines the operation for the broadcast manager to carry out,
+or details the broadcast managers response to several events, including
+user requests.
+
+Transmit Operations (user space to broadcast manager):
+
+TX_SETUP:
+ Create (cyclic) transmission task.
+
+TX_DELETE:
+ Remove (cyclic) transmission task, requires only can_id.
+
+TX_READ:
+ Read properties of (cyclic) transmission task for can_id.
+
+TX_SEND:
+ Send one CAN frame.
+
+Transmit Responses (broadcast manager to user space):
+
+TX_STATUS:
+ Reply to TX_READ request (transmission task configuration).
+
+TX_EXPIRED:
+ Notification when counter finishes sending at initial interval
+ 'ival1'. Requires the TX_COUNTEVT flag to be set at TX_SETUP.
+
+Receive Operations (user space to broadcast manager):
+
+RX_SETUP:
+ Create RX content filter subscription.
+
+RX_DELETE:
+ Remove RX content filter subscription, requires only can_id.
+
+RX_READ:
+ Read properties of RX content filter subscription for can_id.
+
+Receive Responses (broadcast manager to user space):
+
+RX_STATUS:
+ Reply to RX_READ request (filter task configuration).
+
+RX_TIMEOUT:
+ Cyclic message is detected to be absent (timer ival1 expired).
+
+RX_CHANGED:
+ BCM message with updated CAN frame (detected content change).
+ Sent on first message received or on receipt of revised CAN messages.
+
+
+Broadcast Manager Message Flags
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When sending a message to the broadcast manager the 'flags' element may
+contain the following flag definitions which influence the behaviour:
+
+SETTIMER:
+ Set the values of ival1, ival2 and count
+
+STARTTIMER:
+ Start the timer with the actual values of ival1, ival2
+ and count. Starting the timer leads simultaneously to emit a CAN frame.
+
+TX_COUNTEVT:
+ Create the message TX_EXPIRED when count expires
+
+TX_ANNOUNCE:
+ A change of data by the process is emitted immediately.
+
+TX_CP_CAN_ID:
+ Copies the can_id from the message header to each
+ subsequent frame in frames. This is intended as usage simplification. For
+ TX tasks the unique can_id from the message header may differ from the
+ can_id(s) stored for transmission in the subsequent struct can_frame(s).
+
+RX_FILTER_ID:
+ Filter by can_id alone, no frames required (nframes=0).
+
+RX_CHECK_DLC:
+ A change of the DLC leads to an RX_CHANGED.
+
+RX_NO_AUTOTIMER:
+ Prevent automatically starting the timeout monitor.
+
+RX_ANNOUNCE_RESUME:
+ If passed at RX_SETUP and a receive timeout occurred, a
+ RX_CHANGED message will be generated when the (cyclic) receive restarts.
+
+TX_RESET_MULTI_IDX:
+ Reset the index for the multiple frame transmission.
+
+RX_RTR_FRAME:
+ Send reply for RTR-request (placed in op->frames[0]).
+
+
+Broadcast Manager Transmission Timers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Periodic transmission configurations may use up to two interval timers.
+In this case the BCM sends a number of messages ('count') at an interval
+'ival1', then continuing to send at another given interval 'ival2'. When
+only one timer is needed 'count' is set to zero and only 'ival2' is used.
+When SET_TIMER and START_TIMER flag were set the timers are activated.
+The timer values can be altered at runtime when only SET_TIMER is set.
+
+
+Broadcast Manager message sequence transmission
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Up to 256 CAN frames can be transmitted in a sequence in the case of a cyclic
+TX task configuration. The number of CAN frames is provided in the 'nframes'
+element of the BCM message head. The defined number of CAN frames are added
+as array to the TX_SETUP BCM configuration message:
+
+.. code-block:: C
+
+ /* create a struct to set up a sequence of four CAN frames */
+ struct {
+ struct bcm_msg_head msg_head;
+ struct can_frame frame[4];
+ } mytxmsg;
+
+ (..)
+ mytxmsg.msg_head.nframes = 4;
+ (..)
+
+ write(s, &mytxmsg, sizeof(mytxmsg));
+
+With every transmission the index in the array of CAN frames is increased
+and set to zero at index overflow.
+
+
+Broadcast Manager Receive Filter Timers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The timer values ival1 or ival2 may be set to non-zero values at RX_SETUP.
+When the SET_TIMER flag is set the timers are enabled:
+
+ival1:
+ Send RX_TIMEOUT when a received message is not received again within
+ the given time. When START_TIMER is set at RX_SETUP the timeout detection
+ is activated directly - even without a former CAN frame reception.
+
+ival2:
+ Throttle the received message rate down to the value of ival2. This
+ is useful to reduce messages for the application when the signal inside the
+ CAN frame is stateless as state changes within the ival2 periode may get
+ lost.
+
+Broadcast Manager Multiplex Message Receive Filter
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To filter for content changes in multiplex message sequences an array of more
+than one CAN frames can be passed in a RX_SETUP configuration message. The
+data bytes of the first CAN frame contain the mask of relevant bits that
+have to match in the subsequent CAN frames with the received CAN frame.
+If one of the subsequent CAN frames is matching the bits in that frame data
+mark the relevant content to be compared with the previous received content.
+Up to 257 CAN frames (multiplex filter bit mask CAN frame plus 256 CAN
+filters) can be added as array to the TX_SETUP BCM configuration message:
+
+.. code-block:: C
+
+ /* usually used to clear CAN frame data[] - beware of endian problems! */
+ #define U64_DATA(p) (*(unsigned long long*)(p)->data)
+
+ struct {
+ struct bcm_msg_head msg_head;
+ struct can_frame frame[5];
+ } msg;
+
+ msg.msg_head.opcode = RX_SETUP;
+ msg.msg_head.can_id = 0x42;
+ msg.msg_head.flags = 0;
+ msg.msg_head.nframes = 5;
+ U64_DATA(&msg.frame[0]) = 0xFF00000000000000ULL; /* MUX mask */
+ U64_DATA(&msg.frame[1]) = 0x01000000000000FFULL; /* data mask (MUX 0x01) */
+ U64_DATA(&msg.frame[2]) = 0x0200FFFF000000FFULL; /* data mask (MUX 0x02) */
+ U64_DATA(&msg.frame[3]) = 0x330000FFFFFF0003ULL; /* data mask (MUX 0x33) */
+ U64_DATA(&msg.frame[4]) = 0x4F07FC0FF0000000ULL; /* data mask (MUX 0x4F) */
+
+ write(s, &msg, sizeof(msg));
+
+
+Broadcast Manager CAN FD Support
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The programming API of the CAN_BCM depends on struct can_frame which is
+given as array directly behind the bcm_msg_head structure. To follow this
+schema for the CAN FD frames a new flag 'CAN_FD_FRAME' in the bcm_msg_head
+flags indicates that the concatenated CAN frame structures behind the
+bcm_msg_head are defined as struct canfd_frame:
+
+.. code-block:: C
+
+ struct {
+ struct bcm_msg_head msg_head;
+ struct canfd_frame frame[5];
+ } msg;
+
+ msg.msg_head.opcode = RX_SETUP;
+ msg.msg_head.can_id = 0x42;
+ msg.msg_head.flags = CAN_FD_FRAME;
+ msg.msg_head.nframes = 5;
+ (..)
+
+When using CAN FD frames for multiplex filtering the MUX mask is still
+expected in the first 64 bit of the struct canfd_frame data section.
+

+Connected Transport Protocols (SOCK_SEQPACKET)
+----------------------------------------------
+
+(to be written)
+
+
+Unconnected Transport Protocols (SOCK_DGRAM)
+--------------------------------------------
+
+(to be written)
+
+
+.. _socketcan-core-module:
+
+SocketCAN Core Module
+=====================
+
+The SocketCAN core module implements the protocol family
+PF_CAN. CAN protocol modules are loaded by the core module at
+runtime. The core module provides an interface for CAN protocol
+modules to subscribe needed CAN IDs (see :ref:`socketcan-receive-lists`).
+
+
+can.ko Module Params
+--------------------
+
+- **stats_timer**:
+ To calculate the SocketCAN core statistics
+ (e.g. current/maximum frames per second) this 1 second timer is
+ invoked at can.ko module start time by default. This timer can be
+ disabled by using stattimer=0 on the module commandline.
+
+- **debug**:
+ (removed since SocketCAN SVN r546)
+
+
+procfs content
+--------------
+
+As described in :ref:`socketcan-receive-lists` the SocketCAN core uses several filter
+lists to deliver received CAN frames to CAN protocol modules. These
+receive lists, their filters and the count of filter matches can be
+checked in the appropriate receive list. All entries contain the
+device and a protocol module identifier::
+
+ foo@bar:~$ cat /proc/net/can/rcvlist_all
+
+ receive list 'rx_all':
+ (vcan3: no entry)
+ (vcan2: no entry)
+ (vcan1: no entry)
+ device can_id can_mask function userdata matches ident
+ vcan0 000 00000000 f88e6370 f6c6f400 0 raw
+ (any: no entry)
+
+In this example an application requests any CAN traffic from vcan0::
+
+ rcvlist_all - list for unfiltered entries (no filter operations)
+ rcvlist_eff - list for single extended frame (EFF) entries
+ rcvlist_err - list for error message frames masks
+ rcvlist_fil - list for mask/value filters
+ rcvlist_inv - list for mask/value filters (inverse semantic)
+ rcvlist_sff - list for single standard frame (SFF) entries
+
+Additional procfs files in /proc/net/can::
+
+ stats - SocketCAN core statistics (rx/tx frames, match ratios, ...)
+ reset_stats - manual statistic reset
+ version - prints the SocketCAN core version and the ABI version
+
+
+Writing Own CAN Protocol Modules
+--------------------------------
+
+To implement a new protocol in the protocol family PF_CAN a new
+protocol has to be defined in include/linux/can.h .
+The prototypes and definitions to use the SocketCAN core can be
+accessed by including include/linux/can/core.h .
+In addition to functions that register the CAN protocol and the
+CAN device notifier chain there are functions to subscribe CAN
+frames received by CAN interfaces and to send CAN frames::
+
+ can_rx_register - subscribe CAN frames from a specific interface
+ can_rx_unregister - unsubscribe CAN frames from a specific interface
+ can_send - transmit a CAN frame (optional with local loopback)
+
+For details see the kerneldoc documentation in net/can/af_can.c or
+the source code of net/can/raw.c or net/can/bcm.c .
+
+
+CAN Network Drivers
+===================
+
+Writing a CAN network device driver is much easier than writing a
+CAN character device driver. Similar to other known network device
+drivers you mainly have to deal with:
+
+- TX: Put the CAN frame from the socket buffer to the CAN controller.
+- RX: Put the CAN frame from the CAN controller to the socket buffer.
+
+See e.g. at Documentation/networking/netdevices.txt . The differences
+for writing CAN network device driver are described below:
+
+
+General Settings
+----------------
+
+.. code-block:: C
+
+ dev->type = ARPHRD_CAN; /* the netdevice hardware type */
+ dev->flags = IFF_NOARP; /* CAN has no arp */
+
+ dev->mtu = CAN_MTU; /* sizeof(struct can_frame) -> legacy CAN interface */
+
+ or alternative, when the controller supports CAN with flexible data rate:
+ dev->mtu = CANFD_MTU; /* sizeof(struct canfd_frame) -> CAN FD interface */
+
+The struct can_frame or struct canfd_frame is the payload of each socket
+buffer (skbuff) in the protocol family PF_CAN.
+
+
+.. _socketcan-local-loopback2:
+
+Local Loopback of Sent Frames
+-----------------------------
+
+As described in :ref:`socketcan-local-loopback1` the CAN network device driver should
+support a local loopback functionality similar to the local echo
+e.g. of tty devices. In this case the driver flag IFF_ECHO has to be
+set to prevent the PF_CAN core from locally echoing sent frames
+(aka loopback) as fallback solution::
+
+ dev->flags = (IFF_NOARP | IFF_ECHO);
+
+
+CAN Controller Hardware Filters
+-------------------------------
+
+To reduce the interrupt load on deep embedded systems some CAN
+controllers support the filtering of CAN IDs or ranges of CAN IDs.
+These hardware filter capabilities vary from controller to
+controller and have to be identified as not feasible in a multi-user
+networking approach. The use of the very controller specific
+hardware filters could make sense in a very dedicated use-case, as a
+filter on driver level would affect all users in the multi-user
+system. The high efficient filter sets inside the PF_CAN core allow
+to set different multiple filters for each socket separately.
+Therefore the use of hardware filters goes to the category 'handmade
+tuning on deep embedded systems'. The author is running a MPC603e
+@133MHz with four SJA1000 CAN controllers from 2002 under heavy bus
+load without any problems ...
+
+
+The Virtual CAN Driver (vcan)
+-----------------------------
+
+Similar to the network loopback devices, vcan offers a virtual local
+CAN interface. A full qualified address on CAN consists of
+
+- a unique CAN Identifier (CAN ID)
+- the CAN bus this CAN ID is transmitted on (e.g. can0)
+
+so in common use cases more than one virtual CAN interface is needed.
+
+The virtual CAN interfaces allow the transmission and reception of CAN
+frames without real CAN controller hardware. Virtual CAN network
+devices are usually named 'vcanX', like vcan0 vcan1 vcan2 ...
+When compiled as a module the virtual CAN driver module is called vcan.ko
+
+Since Linux Kernel version 2.6.24 the vcan driver supports the Kernel
+netlink interface to create vcan network devices. The creation and
+removal of vcan network devices can be managed with the ip(8) tool::
+
+ - Create a virtual CAN network interface:
+ $ ip link add type vcan
+
+ - Create a virtual CAN network interface with a specific name 'vcan42':
+ $ ip link add dev vcan42 type vcan
+
+ - Remove a (virtual CAN) network interface 'vcan42':
+ $ ip link del vcan42
+
+
+The CAN Network Device Driver Interface
+---------------------------------------
+
+The CAN network device driver interface provides a generic interface
+to setup, configure and monitor CAN network devices. The user can then
+configure the CAN device, like setting the bit-timing parameters, via
+the netlink interface using the program "ip" from the "IPROUTE2"
+utility suite. The following chapter describes briefly how to use it.
+Furthermore, the interface uses a common data structure and exports a
+set of common functions, which all real CAN network device drivers
+should use. Please have a look to the SJA1000 or MSCAN driver to
+understand how to use them. The name of the module is can-dev.ko.
+
+
+Netlink interface to set/get devices properties
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The CAN device must be configured via netlink interface. The supported
+netlink message types are defined and briefly described in
+"include/linux/can/netlink.h". CAN link support for the program "ip"
+of the IPROUTE2 utility suite is available and it can be used as shown
+below:
+

+
+Setting the CAN Bit-Timing
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The CAN bit-timing parameters can always be defined in a hardware
+independent format as proposed in the Bosch CAN 2.0 specification
+specifying the arguments "tq", "prop_seg", "phase_seg1", "phase_seg2"
+and "sjw"::
+
+ $ ip link set canX type can tq 125 prop-seg 6 \
+ phase-seg1 7 phase-seg2 2 sjw 1
+
+If the kernel option CONFIG_CAN_CALC_BITTIMING is enabled, CIA
+recommended CAN bit-timing parameters will be calculated if the bit-
+rate is specified with the argument "bitrate"::
+
+ $ ip link set canX type can bitrate 125000
+
+Note that this works fine for the most common CAN controllers with
+standard bit-rates but may *fail* for exotic bit-rates or CAN system
+clock frequencies. Disabling CONFIG_CAN_CALC_BITTIMING saves some
+space and allows user-space tools to solely determine and set the
+bit-timing parameters. The CAN controller specific bit-timing
+constants can be used for that purpose. They are listed by the
+following command::
+
+ $ ip -details link show can0
+ ...
+ sja1000: clock 8000000 tseg1 1..16 tseg2 1..8 sjw 1..4 brp 1..64 brp-inc 1
+
+
+Starting and Stopping the CAN Network Device
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A CAN network device is started or stopped as usual with the command
+"ifconfig canX up/down" or "ip link set canX up/down". Be aware that
+you *must* define proper bit-timing parameters for real CAN devices
+before you can start it to avoid error-prone default settings::
+
+ $ ip link set canX up type can bitrate 125000
+
+A device may enter the "bus-off" state if too many errors occurred on
+the CAN bus. Then no more messages are received or sent. An automatic
+bus-off recovery can be enabled by setting the "restart-ms" to a
+non-zero value, e.g.::
+
+ $ ip link set canX type can restart-ms 100
+
+Alternatively, the application may realize the "bus-off" condition
+by monitoring CAN error message frames and do a restart when
+appropriate with the command::
+
+ $ ip link set canX type can restart
+
+Note that a restart will also create a CAN error message frame (see
+also :ref:`socketcan-network-problem-notifications`).

+
+CAN FD (Flexible Data Rate) Driver Support
+------------------------------------------
+
+CAN FD capable CAN controllers support two different bitrates for the
+arbitration phase and the payload phase of the CAN FD frame. Therefore a
+second bit timing has to be specified in order to enable the CAN FD bitrate.
+
+Additionally CAN FD capable CAN controllers support up to 64 bytes of
+payload. The representation of this length in can_frame.can_dlc and
+canfd_frame.len for userspace applications and inside the Linux network
+layer is a plain value from 0 .. 64 instead of the CAN 'data length code'.
+The data length code was a 1:1 mapping to the payload length in the legacy
+CAN frames anyway. The payload length to the bus-relevant DLC mapping is
+only performed inside the CAN drivers, preferably with the helper
+functions can_dlc2len() and can_len2dlc().
+
+The CAN netdevice driver capabilities can be distinguished by the network
+devices maximum transfer unit (MTU)::
+
+ MTU = 16 (CAN_MTU) => sizeof(struct can_frame) => 'legacy' CAN device
+ MTU = 72 (CANFD_MTU) => sizeof(struct canfd_frame) => CAN FD capable device
+
+The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.
+N.B. CAN FD capable devices can also handle and send legacy CAN frames.
+
+When configuring CAN FD capable CAN controllers an additional 'data' bitrate
+has to be set. This bitrate for the data phase of the CAN FD frame has to be
+at least the bitrate which was configured for the arbitration phase. This
+second bitrate is specified analogue to the first bitrate but the bitrate
+setting keywords for the 'data' bitrate start with 'd' e.g. dbitrate,
+dsample-point, dsjw or dtq and similar settings. When a data bitrate is set
+within the configuration process the controller option "fd on" can be
+specified to enable the CAN FD mode in the CAN controller. This controller
+option also switches the device MTU to 72 (CANFD_MTU).
+
+The first CAN FD specification presented as whitepaper at the International
+CAN Conference 2012 needed to be improved for data integrity reasons.
+Therefore two CAN FD implementations have to be distinguished today:
+
+- ISO compliant: The ISO 11898-1:2015 CAN FD implementation (default)
+- non-ISO compliant: The CAN FD implementation following the 2012 whitepaper
+
+Finally there are three types of CAN FD controllers:
+
+1. ISO compliant (fixed)
+2. non-ISO compliant (fixed, like the M_CAN IP core v3.0.1 in m_can.c)
+3. ISO/non-ISO CAN FD controllers (switchable, like the PEAK PCAN-USB FD)
+
+The current ISO/non-ISO mode is announced by the CAN controller driver via
+netlink and displayed by the 'ip' tool (controller option FD-NON-ISO).
+The ISO/non-ISO-mode can be altered by setting 'fd-non-iso {on|off}' for
+switchable CAN FD controllers only.
+
+Example configuring 500 kbit/s arbitration bitrate and 4 Mbit/s data bitrate::
+
+ $ ip link set can0 up type can bitrate 500000 sample-point 0.75 \
+ dbitrate 4000000 dsample-point 0.8 fd on
+ $ ip -details link show can0
+ 5: can0: <NOARP,UP,LOWER_UP,ECHO> mtu 72 qdisc pfifo_fast state UNKNOWN \
+ mode DEFAULT group default qlen 10
+ link/can promiscuity 0
+ can <FD> state ERROR-ACTIVE (berr-counter tx 0 rx 0) restart-ms 0
+ bitrate 500000 sample-point 0.750
+ tq 50 prop-seg 14 phase-seg1 15 phase-seg2 10 sjw 1
+ pcan_usb_pro_fd: tseg1 1..64 tseg2 1..16 sjw 1..16 brp 1..1024 \
+ brp-inc 1
+ dbitrate 4000000 dsample-point 0.800
+ dtq 12 dprop-seg 7 dphase-seg1 8 dphase-seg2 4 dsjw 1
+ pcan_usb_pro_fd: dtseg1 1..16 dtseg2 1..8 dsjw 1..4 dbrp 1..1024 \
+ dbrp-inc 1
+ clock 80000000
+
+Example when 'fd-non-iso on' is added on this switchable CAN FD adapter::
+
+ can <FD,FD-NON-ISO> state ERROR-ACTIVE (berr-counter tx 0 rx 0) restart-ms 0

-1. Overview / What is SocketCAN
---------------------------------
-
-The socketcan package is an implementation of CAN protocols
-(Controller Area Network) for Linux. CAN is a networking technology
-which has widespread use in automation, embedded devices, and
-automotive fields. While there have been other CAN implementations
-for Linux based on character devices, SocketCAN uses the Berkeley
-socket API, the Linux network stack and implements the CAN device
-drivers as network interfaces. The CAN socket API has been designed
-as similar as possible to the TCP/IP protocols to allow programmers,
-familiar with network programming, to easily learn how to use CAN
-sockets.
-
-2. Motivation / Why using the socket API
-----------------------------------------
-
-There have been CAN implementations for Linux before SocketCAN so the
-question arises, why we have started another project. Most existing
-implementations come as a device driver for some CAN hardware, they
-are based on character devices and provide comparatively little
-functionality. Usually, there is only a hardware-specific device
-driver which provides a character device interface to send and
-receive raw CAN frames, directly to/from the controller hardware.
-Queueing of frames and higher-level transport protocols like ISO-TP
-have to be implemented in user space applications. Also, most
-character-device implementations support only one single process to
-open the device at a time, similar to a serial interface. Exchanging
-the CAN controller requires employment of another device driver and
-often the need for adaption of large parts of the application to the
-new driver's API.
-
-SocketCAN was designed to overcome all of these limitations. A new
-protocol family has been implemented which provides a socket interface
-to user space applications and which builds upon the Linux network
-layer, enabling use all of the provided queueing functionality. A device
-driver for CAN controller hardware registers itself with the Linux
-network layer as a network device, so that CAN frames from the
-controller can be passed up to the network layer and on to the CAN
-protocol family module and also vice-versa. Also, the protocol family
-module provides an API for transport protocol modules to register, so
-that any number of transport protocols can be loaded or unloaded
-dynamically. In fact, the can core module alone does not provide any
-protocol and cannot be used without loading at least one additional
-protocol module. Multiple sockets can be opened at the same time,
-on different or the same protocol module and they can listen/send
-frames on different or the same CAN IDs. Several sockets listening on
-the same interface for frames with the same CAN ID are all passed the
-same received matching CAN frames. An application wishing to
-communicate using a specific transport protocol, e.g. ISO-TP, just
-selects that protocol when opening the socket, and then can read and
-write application data byte streams, without having to deal with
-CAN-IDs, frames, etc.
-
-Similar functionality visible from user-space could be provided by a
-character device, too, but this would lead to a technically inelegant
-solution for a couple of reasons:
-
-* Intricate usage. Instead of passing a protocol argument to
- socket(2) and using bind(2) to select a CAN interface and CAN ID, an
- application would have to do all these operations using ioctl(2)s.
-
-* Code duplication. A character device cannot make use of the Linux
- network queueing code, so all that code would have to be duplicated
- for CAN networking.
-
-* Abstraction. In most existing character-device implementations, the
- hardware-specific device driver for a CAN controller directly
- provides the character device for the application to work with.
- This is at least very unusual in Unix systems for both, char and
- block devices. For example you don't have a character device for a
- certain UART of a serial interface, a certain sound chip in your
- computer, a SCSI or IDE controller providing access to your hard
- disk or tape streamer device. Instead, you have abstraction layers
- which provide a unified character or block device interface to the
- application on the one hand, and a interface for hardware-specific
- device drivers on the other hand. These abstractions are provided
- by subsystems like the tty layer, the audio subsystem or the SCSI
- and IDE subsystems for the devices mentioned above.
-
- The easiest way to implement a CAN device driver is as a character
- device without such a (complete) abstraction layer, as is done by most
- existing drivers. The right way, however, would be to add such a
- layer with all the functionality like registering for certain CAN
- IDs, supporting several open file descriptors and (de)multiplexing
- CAN frames between them, (sophisticated) queueing of CAN frames, and
- providing an API for device drivers to register with. However, then
- it would be no more difficult, or may be even easier, to use the
- networking framework provided by the Linux kernel, and this is what
- SocketCAN does.
-
- The use of the networking framework of the Linux kernel is just the
- natural and most appropriate way to implement CAN for Linux.
-
-3. SocketCAN concept
----------------------
-
- As described in chapter 2 it is the main goal of SocketCAN to
- provide a socket interface to user space applications which builds
- upon the Linux network layer. In contrast to the commonly known
- TCP/IP and ethernet networking, the CAN bus is a broadcast-only(!)
- medium that has no MAC-layer addressing like ethernet. The CAN-identifier
- (can_id) is used for arbitration on the CAN-bus. Therefore the CAN-IDs
- have to be chosen uniquely on the bus. When designing a CAN-ECU
- network the CAN-IDs are mapped to be sent by a specific ECU.
- For this reason a CAN-ID can be treated best as a kind of source address.
-
- 3.1 receive lists
-
- The network transparent access of multiple applications leads to the
- problem that different applications may be interested in the same
- CAN-IDs from the same CAN network interface. The SocketCAN core
- module - which implements the protocol family CAN - provides several
- high efficient receive lists for this reason. If e.g. a user space
- application opens a CAN RAW socket, the raw protocol module itself
- requests the (range of) CAN-IDs from the SocketCAN core that are
- requested by the user. The subscription and unsubscription of
- CAN-IDs can be done for specific CAN interfaces or for all(!) known
- CAN interfaces with the can_rx_(un)register() functions provided to
- CAN protocol modules by the SocketCAN core (see chapter 5).
- To optimize the CPU usage at runtime the receive lists are split up
- into several specific lists per device that match the requested
- filter complexity for a given use-case.
-
- 3.2 local loopback of sent frames
-
- As known from other networking concepts the data exchanging
- applications may run on the same or different nodes without any
- change (except for the according addressing information):
-
- ___ ___ ___ _______ ___
- | _ | | _ | | _ | | _ _ | | _ |
- ||A|| ||B|| ||C|| ||A| |B|| ||C||
- |___| |___| |___| |_______| |___|
- | | | | |
- -----------------(1)- CAN bus -(2)---------------
-
- To ensure that application A receives the same information in the
- example (2) as it would receive in example (1) there is need for
- some kind of local loopback of the sent CAN frames on the appropriate
- node.
-
- The Linux network devices (by default) just can handle the
- transmission and reception of media dependent frames. Due to the
- arbitration on the CAN bus the transmission of a low prio CAN-ID
- may be delayed by the reception of a high prio CAN frame. To
- reflect the correct* traffic on the node the loopback of the sent
- data has to be performed right after a successful transmission. If
- the CAN network interface is not capable of performing the loopback for
- some reason the SocketCAN core can do this task as a fallback solution.
- See chapter 6.2 for details (recommended).
-
- The loopback functionality is enabled by default to reflect standard
- networking behaviour for CAN applications. Due to some requests from
- the RT-SocketCAN group the loopback optionally may be disabled for each
- separate socket. See sockopts from the CAN RAW sockets in chapter 4.1.
-
- * = you really like to have this when you're running analyser tools
- like 'candump' or 'cansniffer' on the (same) node.
-
- 3.3 network problem notifications
-
- The use of the CAN bus may lead to several problems on the physical
- and media access control layer. Detecting and logging of these lower
- layer problems is a vital requirement for CAN users to identify
- hardware issues on the physical transceiver layer as well as
- arbitration problems and error frames caused by the different
- ECUs. The occurrence of detected errors are important for diagnosis
- and have to be logged together with the exact timestamp. For this
- reason the CAN interface driver can generate so called Error Message
- Frames that can optionally be passed to the user application in the
- same way as other CAN frames. Whenever an error on the physical layer
- or the MAC layer is detected (e.g. by the CAN controller) the driver
- creates an appropriate error message frame. Error messages frames can
- be requested by the user application using the common CAN filter
- mechanisms. Inside this filter definition the (interested) type of
- errors may be selected. The reception of error messages is disabled
- by default. The format of the CAN error message frame is briefly
- described in the Linux header file "include/uapi/linux/can/error.h".
-
-4. How to use SocketCAN
-------------------------
-
- Like TCP/IP, you first need to open a socket for communicating over a
- CAN network. Since SocketCAN implements a new protocol family, you
- need to pass PF_CAN as the first argument to the socket(2) system
- call. Currently, there are two CAN protocols to choose from, the raw
- socket protocol and the broadcast manager (BCM). So to open a socket,
- you would write
-
- s = socket(PF_CAN, SOCK_RAW, CAN_RAW);
-
- and
-
- s = socket(PF_CAN, SOCK_DGRAM, CAN_BCM);
-
- respectively. After the successful creation of the socket, you would
- normally use the bind(2) system call to bind the socket to a CAN
- interface (which is different from TCP/IP due to different addressing
- - see chapter 3). After binding (CAN_RAW) or connecting (CAN_BCM)
- the socket, you can read(2) and write(2) from/to the socket or use
- send(2), sendto(2), sendmsg(2) and the recv* counterpart operations
- on the socket as usual. There are also CAN specific socket options
- described below.
-
- The basic CAN frame structure and the sockaddr structure are defined
- in include/linux/can.h:
-
- struct can_frame {
- canid_t can_id; /* 32 bit CAN_ID + EFF/RTR/ERR flags */
- __u8 can_dlc; /* frame payload length in byte (0 .. 8) */
- __u8 __pad; /* padding */
- __u8 __res0; /* reserved / padding */
- __u8 __res1; /* reserved / padding */
- __u8 data[8] __attribute__((aligned(8)));
- };
-
- The alignment of the (linear) payload data[] to a 64bit boundary
- allows the user to define their own structs and unions to easily access
- the CAN payload. There is no given byteorder on the CAN bus by
- default. A read(2) system call on a CAN_RAW socket transfers a
- struct can_frame to the user space.
-
- The sockaddr_can structure has an interface index like the
- PF_PACKET socket, that also binds to a specific interface:
-
- struct sockaddr_can {
- sa_family_t can_family;
- int can_ifindex;
- union {
- /* transport protocol class address info (e.g. ISOTP) */
- struct { canid_t rx_id, tx_id; } tp;
-
- /* reserved for future CAN protocols address information */
- } can_addr;
- };
-
- To determine the interface index an appropriate ioctl() has to
- be used (example for CAN_RAW sockets without error checking):
-
- int s;
- struct sockaddr_can addr;
- struct ifreq ifr;
-
- s = socket(PF_CAN, SOCK_RAW, CAN_RAW);
-
- strcpy(ifr.ifr_name, "can0" );
- ioctl(s, SIOCGIFINDEX, &ifr);
-
- addr.can_family = AF_CAN;
- addr.can_ifindex = ifr.ifr_ifindex;
-
- bind(s, (struct sockaddr *)&addr, sizeof(addr));
-
- (..)
-
- To bind a socket to all(!) CAN interfaces the interface index must
- be 0 (zero). In this case the socket receives CAN frames from every
- enabled CAN interface. To determine the originating CAN interface
- the system call recvfrom(2) may be used instead of read(2). To send
- on a socket that is bound to 'any' interface sendto(2) is needed to
- specify the outgoing interface.
-
- Reading CAN frames from a bound CAN_RAW socket (see above) consists
- of reading a struct can_frame:
-
- struct can_frame frame;
-
- nbytes = read(s, &frame, sizeof(struct can_frame));
-
- if (nbytes < 0) {
- perror("can raw socket read");
- return 1;
- }
-
- /* paranoid check ... */
- if (nbytes < sizeof(struct can_frame)) {
- fprintf(stderr, "read: incomplete CAN frame\n");
- return 1;
- }
-
- /* do something with the received CAN frame */
-
- Writing CAN frames can be done similarly, with the write(2) system call:
-
- nbytes = write(s, &frame, sizeof(struct can_frame));
-
- When the CAN interface is bound to 'any' existing CAN interface
- (addr.can_ifindex = 0) it is recommended to use recvfrom(2) if the
- information about the originating CAN interface is needed:
-
- struct sockaddr_can addr;
- struct ifreq ifr;
- socklen_t len = sizeof(addr);
- struct can_frame frame;
-
- nbytes = recvfrom(s, &frame, sizeof(struct can_frame),
- 0, (struct sockaddr*)&addr, &len);
-
- /* get interface name of the received CAN frame */
- ifr.ifr_ifindex = addr.can_ifindex;
- ioctl(s, SIOCGIFNAME, &ifr);
- printf("Received a CAN frame from interface %s", ifr.ifr_name);
-
- To write CAN frames on sockets bound to 'any' CAN interface the
- outgoing interface has to be defined certainly.
-
- strcpy(ifr.ifr_name, "can0");
- ioctl(s, SIOCGIFINDEX, &ifr);
- addr.can_ifindex = ifr.ifr_ifindex;
- addr.can_family = AF_CAN;
-
- nbytes = sendto(s, &frame, sizeof(struct can_frame),
- 0, (struct sockaddr*)&addr, sizeof(addr));
-
- An accurate timestamp can be obtained with an ioctl(2) call after reading
- a message from the socket:
-
- struct timeval tv;
- ioctl(s, SIOCGSTAMP, &tv);
-
- The timestamp has a resolution of one microsecond and is set automatically
- at the reception of a CAN frame.
-
- Remark about CAN FD (flexible data rate) support:
-
- Generally the handling of CAN FD is very similar to the formerly described
- examples. The new CAN FD capable CAN controllers support two different
- bitrates for the arbitration phase and the payload phase of the CAN FD frame
- and up to 64 bytes of payload. This extended payload length breaks all the
- kernel interfaces (ABI) which heavily rely on the CAN frame with fixed eight
- bytes of payload (struct can_frame) like the CAN_RAW socket. Therefore e.g.
- the CAN_RAW socket supports a new socket option CAN_RAW_FD_FRAMES that
- switches the socket into a mode that allows the handling of CAN FD frames
- and (legacy) CAN frames simultaneously (see section 4.1.5).
-
- The struct canfd_frame is defined in include/linux/can.h:
-
- struct canfd_frame {
- canid_t can_id; /* 32 bit CAN_ID + EFF/RTR/ERR flags */
- __u8 len; /* frame payload length in byte (0 .. 64) */
- __u8 flags; /* additional flags for CAN FD */
- __u8 __res0; /* reserved / padding */
- __u8 __res1; /* reserved / padding */
- __u8 data[64] __attribute__((aligned(8)));
- };
-
- The struct canfd_frame and the existing struct can_frame have the can_id,
- the payload length and the payload data at the same offset inside their
- structures. This allows to handle the different structures very similar.
- When the content of a struct can_frame is copied into a struct canfd_frame
- all structure elements can be used as-is - only the data[] becomes extended.
-
- When introducing the struct canfd_frame it turned out that the data length
- code (DLC) of the struct can_frame was used as a length information as the
- length and the DLC has a 1:1 mapping in the range of 0 .. 8. To preserve
- the easy handling of the length information the canfd_frame.len element
- contains a plain length value from 0 .. 64. So both canfd_frame.len and
- can_frame.can_dlc are equal and contain a length information and no DLC.
- For details about the distinction of CAN and CAN FD capable devices and
- the mapping to the bus-relevant data length code (DLC), see chapter 6.6.
-
- The length of the two CAN(FD) frame structures define the maximum transfer
- unit (MTU) of the CAN(FD) network interface and skbuff data length. Two
- definitions are specified for CAN specific MTUs in include/linux/can.h :
-
- #define CAN_MTU (sizeof(struct can_frame)) == 16 => 'legacy' CAN frame
- #define CANFD_MTU (sizeof(struct canfd_frame)) == 72 => CAN FD frame
-
- 4.1 RAW protocol sockets with can_filters (SOCK_RAW)
-
- Using CAN_RAW sockets is extensively comparable to the commonly
- known access to CAN character devices. To meet the new possibilities
- provided by the multi user SocketCAN approach, some reasonable
- defaults are set at RAW socket binding time:
-
- - The filters are set to exactly one filter receiving everything
- - The socket only receives valid data frames (=> no error message frames)
- - The loopback of sent CAN frames is enabled (see chapter 3.2)
- - The socket does not receive its own sent frames (in loopback mode)
-
- These default settings may be changed before or after binding the socket.
- To use the referenced definitions of the socket options for CAN_RAW
- sockets, include <linux/can/raw.h>.
-
- 4.1.1 RAW socket option CAN_RAW_FILTER
-
- The reception of CAN frames using CAN_RAW sockets can be controlled
- by defining 0 .. n filters with the CAN_RAW_FILTER socket option.
-
- The CAN filter structure is defined in include/linux/can.h:
-
- struct can_filter {
- canid_t can_id;
- canid_t can_mask;
- };
-
- A filter matches, when
-
- <received_can_id> & mask == can_id & mask
-
- which is analogous to known CAN controllers hardware filter semantics.
- The filter can be inverted in this semantic, when the CAN_INV_FILTER
- bit is set in can_id element of the can_filter structure. In
- contrast to CAN controller hardware filters the user may set 0 .. n
- receive filters for each open socket separately:
-
- struct can_filter rfilter[2];
-
- rfilter[0].can_id = 0x123;
- rfilter[0].can_mask = CAN_SFF_MASK;
- rfilter[1].can_id = 0x200;
- rfilter[1].can_mask = 0x700;
-
- setsockopt(s, SOL_CAN_RAW, CAN_RAW_FILTER, &rfilter, sizeof(rfilter));
-
- To disable the reception of CAN frames on the selected CAN_RAW socket:
-
- setsockopt(s, SOL_CAN_RAW, CAN_RAW_FILTER, NULL, 0);
-
- To set the filters to zero filters is quite obsolete as to not read
- data causes the raw socket to discard the received CAN frames. But
- having this 'send only' use-case we may remove the receive list in the
- Kernel to save a little (really a very little!) CPU usage.
-
- 4.1.1.1 CAN filter usage optimisation
-
- The CAN filters are processed in per-device filter lists at CAN frame
- reception time. To reduce the number of checks that need to be performed
- while walking through the filter lists the CAN core provides an optimized
- filter handling when the filter subscription focusses on a single CAN ID.
-
- For the possible 2048 SFF CAN identifiers the identifier is used as an index
- to access the corresponding subscription list without any further checks.
- For the 2^29 possible EFF CAN identifiers a 10 bit XOR folding is used as
- hash function to retrieve the EFF table index.
-
- To benefit from the optimized filters for single CAN identifiers the
- CAN_SFF_MASK or CAN_EFF_MASK have to be set into can_filter.mask together
- with set CAN_EFF_FLAG and CAN_RTR_FLAG bits. A set CAN_EFF_FLAG bit in the
- can_filter.mask makes clear that it matters whether a SFF or EFF CAN ID is
- subscribed. E.g. in the example from above
-
- rfilter[0].can_id = 0x123;
- rfilter[0].can_mask = CAN_SFF_MASK;
-
- both SFF frames with CAN ID 0x123 and EFF frames with 0xXXXXX123 can pass.
-
- To filter for only 0x123 (SFF) and 0x12345678 (EFF) CAN identifiers the
- filter has to be defined in this way to benefit from the optimized filters:
-
- struct can_filter rfilter[2];
-
- rfilter[0].can_id = 0x123;
- rfilter[0].can_mask = (CAN_EFF_FLAG | CAN_RTR_FLAG | CAN_SFF_MASK);
- rfilter[1].can_id = 0x12345678 | CAN_EFF_FLAG;
- rfilter[1].can_mask = (CAN_EFF_FLAG | CAN_RTR_FLAG | CAN_EFF_MASK);
-
- setsockopt(s, SOL_CAN_RAW, CAN_RAW_FILTER, &rfilter, sizeof(rfilter));
-
- 4.1.2 RAW socket option CAN_RAW_ERR_FILTER
-
- As described in chapter 3.3 the CAN interface driver can generate so
- called Error Message Frames that can optionally be passed to the user
- application in the same way as other CAN frames. The possible
- errors are divided into different error classes that may be filtered
- using the appropriate error mask. To register for every possible
- error condition CAN_ERR_MASK can be used as value for the error mask.
- The values for the error mask are defined in linux/can/error.h .
-
- can_err_mask_t err_mask = ( CAN_ERR_TX_TIMEOUT | CAN_ERR_BUSOFF );
-
- setsockopt(s, SOL_CAN_RAW, CAN_RAW_ERR_FILTER,
- &err_mask, sizeof(err_mask));
-
- 4.1.3 RAW socket option CAN_RAW_LOOPBACK
-
- To meet multi user needs the local loopback is enabled by default
- (see chapter 3.2 for details). But in some embedded use-cases
- (e.g. when only one application uses the CAN bus) this loopback
- functionality can be disabled (separately for each socket):
-
- int loopback = 0; /* 0 = disabled, 1 = enabled (default) */
-
- setsockopt(s, SOL_CAN_RAW, CAN_RAW_LOOPBACK, &loopback, sizeof(loopback));
-
- 4.1.4 RAW socket option CAN_RAW_RECV_OWN_MSGS
-
- When the local loopback is enabled, all the sent CAN frames are
- looped back to the open CAN sockets that registered for the CAN
- frames' CAN-ID on this given interface to meet the multi user
- needs. The reception of the CAN frames on the same socket that was
- sending the CAN frame is assumed to be unwanted and therefore
- disabled by default. This default behaviour may be changed on
- demand:
-
- int recv_own_msgs = 1; /* 0 = disabled (default), 1 = enabled */
-
- setsockopt(s, SOL_CAN_RAW, CAN_RAW_RECV_OWN_MSGS,
- &recv_own_msgs, sizeof(recv_own_msgs));
-
- 4.1.5 RAW socket option CAN_RAW_FD_FRAMES
-
- CAN FD support in CAN_RAW sockets can be enabled with a new socket option
- CAN_RAW_FD_FRAMES which is off by default. When the new socket option is
- not supported by the CAN_RAW socket (e.g. on older kernels), switching the
- CAN_RAW_FD_FRAMES option returns the error -ENOPROTOOPT.
-
- Once CAN_RAW_FD_FRAMES is enabled the application can send both CAN frames
- and CAN FD frames. OTOH the application has to handle CAN and CAN FD frames
- when reading from the socket.
-
- CAN_RAW_FD_FRAMES enabled: CAN_MTU and CANFD_MTU are allowed
- CAN_RAW_FD_FRAMES disabled: only CAN_MTU is allowed (default)
-
- Example:
- [ remember: CANFD_MTU == sizeof(struct canfd_frame) ]
-
- struct canfd_frame cfd;
-
- nbytes = read(s, &cfd, CANFD_MTU);
-
- if (nbytes == CANFD_MTU) {
- printf("got CAN FD frame with length %d\n", cfd.len);
- /* cfd.flags contains valid data */
- } else if (nbytes == CAN_MTU) {
- printf("got legacy CAN frame with length %d\n", cfd.len);
- /* cfd.flags is undefined */
- } else {
- fprintf(stderr, "read: invalid CAN(FD) frame\n");
- return 1;
- }
-
- /* the content can be handled independently from the received MTU size */
-
- printf("can_id: %X data length: %d data: ", cfd.can_id, cfd.len);
- for (i = 0; i < cfd.len; i++)
- printf("%02X ", cfd.data[i]);
-
- When reading with size CANFD_MTU only returns CAN_MTU bytes that have
- been received from the socket a legacy CAN frame has been read into the
- provided CAN FD structure. Note that the canfd_frame.flags data field is
- not specified in the struct can_frame and therefore it is only valid in
- CANFD_MTU sized CAN FD frames.
-
- Implementation hint for new CAN applications:
-
- To build a CAN FD aware application use struct canfd_frame as basic CAN
- data structure for CAN_RAW based applications. When the application is
- executed on an older Linux kernel and switching the CAN_RAW_FD_FRAMES
- socket option returns an error: No problem. You'll get legacy CAN frames
- or CAN FD frames and can process them the same way.
-
- When sending to CAN devices make sure that the device is capable to handle
- CAN FD frames by checking if the device maximum transfer unit is CANFD_MTU.
- The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.
-
- 4.1.6 RAW socket option CAN_RAW_JOIN_FILTERS
-
- The CAN_RAW socket can set multiple CAN identifier specific filters that
- lead to multiple filters in the af_can.c filter processing. These filters
- are indenpendent from each other which leads to logical OR'ed filters when
- applied (see 4.1.1).
-
- This socket option joines the given CAN filters in the way that only CAN
- frames are passed to user space that matched *all* given CAN filters. The
- semantic for the applied filters is therefore changed to a logical AND.
-
- This is useful especially when the filterset is a combination of filters
- where the CAN_INV_FILTER flag is set in order to notch single CAN IDs or
- CAN ID ranges from the incoming traffic.
-
- 4.1.7 RAW socket returned message flags
-
- When using recvmsg() call, the msg->msg_flags may contain following flags:
-
- MSG_DONTROUTE: set when the received frame was created on the local host.
-
- MSG_CONFIRM: set when the frame was sent via the socket it is received on.
- This flag can be interpreted as a 'transmission confirmation' when the
- CAN driver supports the echo of frames on driver level, see 3.2 and 6.2.
- In order to receive such messages, CAN_RAW_RECV_OWN_MSGS must be set.
-
- 4.2 Broadcast Manager protocol sockets (SOCK_DGRAM)
-
- The Broadcast Manager protocol provides a command based configuration
- interface to filter and send (e.g. cyclic) CAN messages in kernel space.
-
- Receive filters can be used to down sample frequent messages; detect events
- such as message contents changes, packet length changes, and do time-out
- monitoring of received messages.
-
- Periodic transmission tasks of CAN frames or a sequence of CAN frames can be
- created and modified at runtime; both the message content and the two
- possible transmit intervals can be altered.
-
- A BCM socket is not intended for sending individual CAN frames using the
- struct can_frame as known from the CAN_RAW socket. Instead a special BCM
- configuration message is defined. The basic BCM configuration message used
- to communicate with the broadcast manager and the available operations are
- defined in the linux/can/bcm.h include. The BCM message consists of a
- message header with a command ('opcode') followed by zero or more CAN frames.
- The broadcast manager sends responses to user space in the same form:
-
- struct bcm_msg_head {
- __u32 opcode; /* command */
- __u32 flags; /* special flags */
- __u32 count; /* run 'count' times with ival1 */
- struct timeval ival1, ival2; /* count and subsequent interval */
- canid_t can_id; /* unique can_id for task */
- __u32 nframes; /* number of can_frames following */
- struct can_frame frames[0];
- };
-
- The aligned payload 'frames' uses the same basic CAN frame structure defined
- at the beginning of section 4 and in the include/linux/can.h include. All
- messages to the broadcast manager from user space have this structure.
-
- Note a CAN_BCM socket must be connected instead of bound after socket
- creation (example without error checking):
-
- int s;
- struct sockaddr_can addr;
- struct ifreq ifr;
-
- s = socket(PF_CAN, SOCK_DGRAM, CAN_BCM);
-
- strcpy(ifr.ifr_name, "can0");
- ioctl(s, SIOCGIFINDEX, &ifr);
-
- addr.can_family = AF_CAN;
- addr.can_ifindex = ifr.ifr_ifindex;
-
- connect(s, (struct sockaddr *)&addr, sizeof(addr));
-
- (..)
-
- The broadcast manager socket is able to handle any number of in flight
- transmissions or receive filters concurrently. The different RX/TX jobs are
- distinguished by the unique can_id in each BCM message. However additional
- CAN_BCM sockets are recommended to communicate on multiple CAN interfaces.
- When the broadcast manager socket is bound to 'any' CAN interface (=> the
- interface index is set to zero) the configured receive filters apply to any
- CAN interface unless the sendto() syscall is used to overrule the 'any' CAN
- interface index. When using recvfrom() instead of read() to retrieve BCM
- socket messages the originating CAN interface is provided in can_ifindex.
-
- 4.2.1 Broadcast Manager operations
-
- The opcode defines the operation for the broadcast manager to carry out,
- or details the broadcast managers response to several events, including
- user requests.
-
- Transmit Operations (user space to broadcast manager):
-
- TX_SETUP: Create (cyclic) transmission task.
-
- TX_DELETE: Remove (cyclic) transmission task, requires only can_id.
-
- TX_READ: Read properties of (cyclic) transmission task for can_id.
-
- TX_SEND: Send one CAN frame.
-
- Transmit Responses (broadcast manager to user space):
-
- TX_STATUS: Reply to TX_READ request (transmission task configuration).
-
- TX_EXPIRED: Notification when counter finishes sending at initial interval
- 'ival1'. Requires the TX_COUNTEVT flag to be set at TX_SETUP.
-
- Receive Operations (user space to broadcast manager):
-
- RX_SETUP: Create RX content filter subscription.
-
- RX_DELETE: Remove RX content filter subscription, requires only can_id.
-
- RX_READ: Read properties of RX content filter subscription for can_id.
-
- Receive Responses (broadcast manager to user space):
-
- RX_STATUS: Reply to RX_READ request (filter task configuration).
-
- RX_TIMEOUT: Cyclic message is detected to be absent (timer ival1 expired).
-
- RX_CHANGED: BCM message with updated CAN frame (detected content change).
- Sent on first message received or on receipt of revised CAN messages.
-
- 4.2.2 Broadcast Manager message flags
-
- When sending a message to the broadcast manager the 'flags' element may
- contain the following flag definitions which influence the behaviour:
-
- SETTIMER: Set the values of ival1, ival2 and count
-
- STARTTIMER: Start the timer with the actual values of ival1, ival2
- and count. Starting the timer leads simultaneously to emit a CAN frame.
-
- TX_COUNTEVT: Create the message TX_EXPIRED when count expires
-
- TX_ANNOUNCE: A change of data by the process is emitted immediately.
-
- TX_CP_CAN_ID: Copies the can_id from the message header to each
- subsequent frame in frames. This is intended as usage simplification. For
- TX tasks the unique can_id from the message header may differ from the
- can_id(s) stored for transmission in the subsequent struct can_frame(s).
-
- RX_FILTER_ID: Filter by can_id alone, no frames required (nframes=0).
-
- RX_CHECK_DLC: A change of the DLC leads to an RX_CHANGED.
-
- RX_NO_AUTOTIMER: Prevent automatically starting the timeout monitor.
-
- RX_ANNOUNCE_RESUME: If passed at RX_SETUP and a receive timeout occurred, a
- RX_CHANGED message will be generated when the (cyclic) receive restarts.
-
- TX_RESET_MULTI_IDX: Reset the index for the multiple frame transmission.
-
- RX_RTR_FRAME: Send reply for RTR-request (placed in op->frames[0]).
-
- 4.2.3 Broadcast Manager transmission timers
-
- Periodic transmission configurations may use up to two interval timers.
- In this case the BCM sends a number of messages ('count') at an interval
- 'ival1', then continuing to send at another given interval 'ival2'. When
- only one timer is needed 'count' is set to zero and only 'ival2' is used.
- When SET_TIMER and START_TIMER flag were set the timers are activated.
- The timer values can be altered at runtime when only SET_TIMER is set.
-
- 4.2.4 Broadcast Manager message sequence transmission
-
- Up to 256 CAN frames can be transmitted in a sequence in the case of a cyclic
- TX task configuration. The number of CAN frames is provided in the 'nframes'
- element of the BCM message head. The defined number of CAN frames are added
- as array to the TX_SETUP BCM configuration message.
-
- /* create a struct to set up a sequence of four CAN frames */
- struct {
- struct bcm_msg_head msg_head;
- struct can_frame frame[4];
- } mytxmsg;
-
- (..)
- mytxmsg.msg_head.nframes = 4;
- (..)
-
- write(s, &mytxmsg, sizeof(mytxmsg));
-
- With every transmission the index in the array of CAN frames is increased
- and set to zero at index overflow.
-
- 4.2.5 Broadcast Manager receive filter timers
-
- The timer values ival1 or ival2 may be set to non-zero values at RX_SETUP.
- When the SET_TIMER flag is set the timers are enabled:
-
- ival1: Send RX_TIMEOUT when a received message is not received again within
- the given time. When START_TIMER is set at RX_SETUP the timeout detection
- is activated directly - even without a former CAN frame reception.
-
- ival2: Throttle the received message rate down to the value of ival2. This
- is useful to reduce messages for the application when the signal inside the
- CAN frame is stateless as state changes within the ival2 periode may get
- lost.
-
- 4.2.6 Broadcast Manager multiplex message receive filter
-
- To filter for content changes in multiplex message sequences an array of more
- than one CAN frames can be passed in a RX_SETUP configuration message. The
- data bytes of the first CAN frame contain the mask of relevant bits that
- have to match in the subsequent CAN frames with the received CAN frame.
- If one of the subsequent CAN frames is matching the bits in that frame data
- mark the relevant content to be compared with the previous received content.
- Up to 257 CAN frames (multiplex filter bit mask CAN frame plus 256 CAN
- filters) can be added as array to the TX_SETUP BCM configuration message.
-
- /* usually used to clear CAN frame data[] - beware of endian problems! */
- #define U64_DATA(p) (*(unsigned long long*)(p)->data)
-
- struct {
- struct bcm_msg_head msg_head;
- struct can_frame frame[5];
- } msg;
-
- msg.msg_head.opcode = RX_SETUP;
- msg.msg_head.can_id = 0x42;
- msg.msg_head.flags = 0;
- msg.msg_head.nframes = 5;
- U64_DATA(&msg.frame[0]) = 0xFF00000000000000ULL; /* MUX mask */
- U64_DATA(&msg.frame[1]) = 0x01000000000000FFULL; /* data mask (MUX 0x01) */
- U64_DATA(&msg.frame[2]) = 0x0200FFFF000000FFULL; /* data mask (MUX 0x02) */
- U64_DATA(&msg.frame[3]) = 0x330000FFFFFF0003ULL; /* data mask (MUX 0x33) */
- U64_DATA(&msg.frame[4]) = 0x4F07FC0FF0000000ULL; /* data mask (MUX 0x4F) */
-
- write(s, &msg, sizeof(msg));
-
- 4.2.7 Broadcast Manager CAN FD support
-
- The programming API of the CAN_BCM depends on struct can_frame which is
- given as array directly behind the bcm_msg_head structure. To follow this
- schema for the CAN FD frames a new flag 'CAN_FD_FRAME' in the bcm_msg_head
- flags indicates that the concatenated CAN frame structures behind the
- bcm_msg_head are defined as struct canfd_frame.
-
- struct {
- struct bcm_msg_head msg_head;
- struct canfd_frame frame[5];
- } msg;
-
- msg.msg_head.opcode = RX_SETUP;
- msg.msg_head.can_id = 0x42;
- msg.msg_head.flags = CAN_FD_FRAME;
- msg.msg_head.nframes = 5;
- (..)
-
- When using CAN FD frames for multiplex filtering the MUX mask is still
- expected in the first 64 bit of the struct canfd_frame data section.
-
- 4.3 connected transport protocols (SOCK_SEQPACKET)
- 4.4 unconnected transport protocols (SOCK_DGRAM)
-
-
-5. SocketCAN core module
--------------------------
-
- The SocketCAN core module implements the protocol family
- PF_CAN. CAN protocol modules are loaded by the core module at
- runtime. The core module provides an interface for CAN protocol
- modules to subscribe needed CAN IDs (see chapter 3.1).
-
- 5.1 can.ko module params
-
- - stats_timer: To calculate the SocketCAN core statistics
- (e.g. current/maximum frames per second) this 1 second timer is
- invoked at can.ko module start time by default. This timer can be
- disabled by using stattimer=0 on the module commandline.
-
- - debug: (removed since SocketCAN SVN r546)
-
- 5.2 procfs content
-
- As described in chapter 3.1 the SocketCAN core uses several filter
- lists to deliver received CAN frames to CAN protocol modules. These
- receive lists, their filters and the count of filter matches can be
- checked in the appropriate receive list. All entries contain the
- device and a protocol module identifier:
-
- foo@bar:~$ cat /proc/net/can/rcvlist_all
-
- receive list 'rx_all':
- (vcan3: no entry)
- (vcan2: no entry)
- (vcan1: no entry)
- device can_id can_mask function userdata matches ident
- vcan0 000 00000000 f88e6370 f6c6f400 0 raw
- (any: no entry)
-
- In this example an application requests any CAN traffic from vcan0.
-
- rcvlist_all - list for unfiltered entries (no filter operations)
- rcvlist_eff - list for single extended frame (EFF) entries
- rcvlist_err - list for error message frames masks
- rcvlist_fil - list for mask/value filters
- rcvlist_inv - list for mask/value filters (inverse semantic)
- rcvlist_sff - list for single standard frame (SFF) entries
-
- Additional procfs files in /proc/net/can
-
- stats - SocketCAN core statistics (rx/tx frames, match ratios, ...)
- reset_stats - manual statistic reset
- version - prints the SocketCAN core version and the ABI version
-
- 5.3 writing own CAN protocol modules
-
- To implement a new protocol in the protocol family PF_CAN a new
- protocol has to be defined in include/linux/can.h .
- The prototypes and definitions to use the SocketCAN core can be
- accessed by including include/linux/can/core.h .
- In addition to functions that register the CAN protocol and the
- CAN device notifier chain there are functions to subscribe CAN
- frames received by CAN interfaces and to send CAN frames:
-
- can_rx_register - subscribe CAN frames from a specific interface
- can_rx_unregister - unsubscribe CAN frames from a specific interface
- can_send - transmit a CAN frame (optional with local loopback)
-
- For details see the kerneldoc documentation in net/can/af_can.c or
- the source code of net/can/raw.c or net/can/bcm.c .
-
-6. CAN network drivers
-----------------------
-
- Writing a CAN network device driver is much easier than writing a
- CAN character device driver. Similar to other known network device
- drivers you mainly have to deal with:
-
- - TX: Put the CAN frame from the socket buffer to the CAN controller.
- - RX: Put the CAN frame from the CAN controller to the socket buffer.
-
- See e.g. at Documentation/networking/netdevices.txt . The differences
- for writing CAN network device driver are described below:
-
- 6.1 general settings
-
- dev->type = ARPHRD_CAN; /* the netdevice hardware type */
- dev->flags = IFF_NOARP; /* CAN has no arp */
-
- dev->mtu = CAN_MTU; /* sizeof(struct can_frame) -> legacy CAN interface */
-
- or alternative, when the controller supports CAN with flexible data rate:
- dev->mtu = CANFD_MTU; /* sizeof(struct canfd_frame) -> CAN FD interface */
-
- The struct can_frame or struct canfd_frame is the payload of each socket
- buffer (skbuff) in the protocol family PF_CAN.
-
- 6.2 local loopback of sent frames
-
- As described in chapter 3.2 the CAN network device driver should
- support a local loopback functionality similar to the local echo
- e.g. of tty devices. In this case the driver flag IFF_ECHO has to be
- set to prevent the PF_CAN core from locally echoing sent frames
- (aka loopback) as fallback solution:
-
- dev->flags = (IFF_NOARP | IFF_ECHO);
-
- 6.3 CAN controller hardware filters
-
- To reduce the interrupt load on deep embedded systems some CAN
- controllers support the filtering of CAN IDs or ranges of CAN IDs.
- These hardware filter capabilities vary from controller to
- controller and have to be identified as not feasible in a multi-user
- networking approach. The use of the very controller specific
- hardware filters could make sense in a very dedicated use-case, as a
- filter on driver level would affect all users in the multi-user
- system. The high efficient filter sets inside the PF_CAN core allow
- to set different multiple filters for each socket separately.
- Therefore the use of hardware filters goes to the category 'handmade
- tuning on deep embedded systems'. The author is running a MPC603e
- @133MHz with four SJA1000 CAN controllers from 2002 under heavy bus
- load without any problems ...
-
- 6.4 The virtual CAN driver (vcan)
-
- Similar to the network loopback devices, vcan offers a virtual local
- CAN interface. A full qualified address on CAN consists of
-
- - a unique CAN Identifier (CAN ID)
- - the CAN bus this CAN ID is transmitted on (e.g. can0)
-
- so in common use cases more than one virtual CAN interface is needed.
-
- The virtual CAN interfaces allow the transmission and reception of CAN
- frames without real CAN controller hardware. Virtual CAN network
- devices are usually named 'vcanX', like vcan0 vcan1 vcan2 ...
- When compiled as a module the virtual CAN driver module is called vcan.ko
-
- Since Linux Kernel version 2.6.24 the vcan driver supports the Kernel
- netlink interface to create vcan network devices. The creation and
- removal of vcan network devices can be managed with the ip(8) tool:
-
- - Create a virtual CAN network interface:
- $ ip link add type vcan
-
- - Create a virtual CAN network interface with a specific name 'vcan42':
- $ ip link add dev vcan42 type vcan
-
- - Remove a (virtual CAN) network interface 'vcan42':
- $ ip link del vcan42
-
- 6.5 The CAN network device driver interface
-
- The CAN network device driver interface provides a generic interface
- to setup, configure and monitor CAN network devices. The user can then
- configure the CAN device, like setting the bit-timing parameters, via
- the netlink interface using the program "ip" from the "IPROUTE2"
- utility suite. The following chapter describes briefly how to use it.
- Furthermore, the interface uses a common data structure and exports a
- set of common functions, which all real CAN network device drivers
- should use. Please have a look to the SJA1000 or MSCAN driver to
- understand how to use them. The name of the module is can-dev.ko.
-
- 6.5.1 Netlink interface to set/get devices properties
-
- The CAN device must be configured via netlink interface. The supported
- netlink message types are defined and briefly described in
- "include/linux/can/netlink.h". CAN link support for the program "ip"
- of the IPROUTE2 utility suite is available and it can be used as shown
- below:
-
- - Setting CAN device properties:
-
- $ ip link set can0 type can help

- More info to the above output:
-
- "<TRIPLE-SAMPLING>"
- Shows the list of selected CAN controller modes: LOOPBACK,
- LISTEN-ONLY, or TRIPLE-SAMPLING.
-
- "state ERROR-ACTIVE"
- The current state of the CAN controller: "ERROR-ACTIVE",
- "ERROR-WARNING", "ERROR-PASSIVE", "BUS-OFF" or "STOPPED"
-
- "restart-ms 100"
- Automatic restart delay time. If set to a non-zero value, a
- restart of the CAN controller will be triggered automatically
- in case of a bus-off condition after the specified delay time
- in milliseconds. By default it's off.
-
- "bitrate 125000 sample-point 0.875"
- Shows the real bit-rate in bits/sec and the sample-point in the
- range 0.000..0.999. If the calculation of bit-timing parameters
- is enabled in the kernel (CONFIG_CAN_CALC_BITTIMING=y), the
- bit-timing can be defined by setting the "bitrate" argument.
- Optionally the "sample-point" can be specified. By default it's
- 0.000 assuming CIA-recommended sample-points.
-
- "tq 125 prop-seg 6 phase-seg1 7 phase-seg2 2 sjw 1"
- Shows the time quanta in ns, propagation segment, phase buffer
- segment 1 and 2 and the synchronisation jump width in units of
- tq. They allow to define the CAN bit-timing in a hardware
- independent format as proposed by the Bosch CAN 2.0 spec (see
- chapter 8 of http://www.semiconductors.bosch.de/pdf/can2spec.pdf).
-
- "sja1000: tseg1 1..16 tseg2 1..8 sjw 1..4 brp 1..64 brp-inc 1
- clock 8000000"
- Shows the bit-timing constants of the CAN controller, here the
- "sja1000". The minimum and maximum values of the time segment 1
- and 2, the synchronisation jump width in units of tq, the
- bitrate pre-scaler and the CAN system clock frequency in Hz.
- These constants could be used for user-defined (non-standard)
- bit-timing calculation algorithms in user-space.
-
- "re-started bus-errors arbit-lost error-warn error-pass bus-off"
- Shows the number of restarts, bus and arbitration lost errors,
- and the state changes to the error-warning, error-passive and
- bus-off state. RX overrun errors are listed in the "overrun"
- field of the standard network statistics.
-
- 6.5.2 Setting the CAN bit-timing
-
- The CAN bit-timing parameters can always be defined in a hardware
- independent format as proposed in the Bosch CAN 2.0 specification
- specifying the arguments "tq", "prop_seg", "phase_seg1", "phase_seg2"
- and "sjw":
-
- $ ip link set canX type can tq 125 prop-seg 6 \
- phase-seg1 7 phase-seg2 2 sjw 1
-
- If the kernel option CONFIG_CAN_CALC_BITTIMING is enabled, CIA
- recommended CAN bit-timing parameters will be calculated if the bit-
- rate is specified with the argument "bitrate":
-
- $ ip link set canX type can bitrate 125000
-
- Note that this works fine for the most common CAN controllers with
- standard bit-rates but may *fail* for exotic bit-rates or CAN system
- clock frequencies. Disabling CONFIG_CAN_CALC_BITTIMING saves some
- space and allows user-space tools to solely determine and set the
- bit-timing parameters. The CAN controller specific bit-timing
- constants can be used for that purpose. They are listed by the
- following command:
-
- $ ip -details link show can0
- ...
- sja1000: clock 8000000 tseg1 1..16 tseg2 1..8 sjw 1..4 brp 1..64 brp-inc 1
-
- 6.5.3 Starting and stopping the CAN network device
-
- A CAN network device is started or stopped as usual with the command
- "ifconfig canX up/down" or "ip link set canX up/down". Be aware that
- you *must* define proper bit-timing parameters for real CAN devices
- before you can start it to avoid error-prone default settings:
-
- $ ip link set canX up type can bitrate 125000
-
- A device may enter the "bus-off" state if too many errors occurred on
- the CAN bus. Then no more messages are received or sent. An automatic
- bus-off recovery can be enabled by setting the "restart-ms" to a
- non-zero value, e.g.:
-
- $ ip link set canX type can restart-ms 100
-
- Alternatively, the application may realize the "bus-off" condition
- by monitoring CAN error message frames and do a restart when
- appropriate with the command:
-
- $ ip link set canX type can restart
-
- Note that a restart will also create a CAN error message frame (see
- also chapter 3.3).
-
- 6.6 CAN FD (flexible data rate) driver support
-
- CAN FD capable CAN controllers support two different bitrates for the
- arbitration phase and the payload phase of the CAN FD frame. Therefore a
- second bit timing has to be specified in order to enable the CAN FD bitrate.
-
- Additionally CAN FD capable CAN controllers support up to 64 bytes of
- payload. The representation of this length in can_frame.can_dlc and
- canfd_frame.len for userspace applications and inside the Linux network
- layer is a plain value from 0 .. 64 instead of the CAN 'data length code'.
- The data length code was a 1:1 mapping to the payload length in the legacy
- CAN frames anyway. The payload length to the bus-relevant DLC mapping is
- only performed inside the CAN drivers, preferably with the helper
- functions can_dlc2len() and can_len2dlc().
-
- The CAN netdevice driver capabilities can be distinguished by the network
- devices maximum transfer unit (MTU):
-
- MTU = 16 (CAN_MTU) => sizeof(struct can_frame) => 'legacy' CAN device
- MTU = 72 (CANFD_MTU) => sizeof(struct canfd_frame) => CAN FD capable device
-
- The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.
- N.B. CAN FD capable devices can also handle and send legacy CAN frames.
-
- When configuring CAN FD capable CAN controllers an additional 'data' bitrate
- has to be set. This bitrate for the data phase of the CAN FD frame has to be
- at least the bitrate which was configured for the arbitration phase. This
- second bitrate is specified analogue to the first bitrate but the bitrate
- setting keywords for the 'data' bitrate start with 'd' e.g. dbitrate,
- dsample-point, dsjw or dtq and similar settings. When a data bitrate is set
- within the configuration process the controller option "fd on" can be
- specified to enable the CAN FD mode in the CAN controller. This controller
- option also switches the device MTU to 72 (CANFD_MTU).
-
- The first CAN FD specification presented as whitepaper at the International
- CAN Conference 2012 needed to be improved for data integrity reasons.
- Therefore two CAN FD implementations have to be distinguished today:
-
- - ISO compliant: The ISO 11898-1:2015 CAN FD implementation (default)
- - non-ISO compliant: The CAN FD implementation following the 2012 whitepaper
-
- Finally there are three types of CAN FD controllers:
-
- 1. ISO compliant (fixed)
- 2. non-ISO compliant (fixed, like the M_CAN IP core v3.0.1 in m_can.c)
- 3. ISO/non-ISO CAN FD controllers (switchable, like the PEAK PCAN-USB FD)
-
- The current ISO/non-ISO mode is announced by the CAN controller driver via
- netlink and displayed by the 'ip' tool (controller option FD-NON-ISO).
- The ISO/non-ISO-mode can be altered by setting 'fd-non-iso {on|off}' for
- switchable CAN FD controllers only.
-
- Example configuring 500 kbit/s arbitration bitrate and 4 Mbit/s data bitrate:
-
- $ ip link set can0 up type can bitrate 500000 sample-point 0.75 \
- dbitrate 4000000 dsample-point 0.8 fd on
- $ ip -details link show can0
- 5: can0: <NOARP,UP,LOWER_UP,ECHO> mtu 72 qdisc pfifo_fast state UNKNOWN \
- mode DEFAULT group default qlen 10
- link/can promiscuity 0
- can <FD> state ERROR-ACTIVE (berr-counter tx 0 rx 0) restart-ms 0
- bitrate 500000 sample-point 0.750
- tq 50 prop-seg 14 phase-seg1 15 phase-seg2 10 sjw 1
- pcan_usb_pro_fd: tseg1 1..64 tseg2 1..16 sjw 1..16 brp 1..1024 \
- brp-inc 1
- dbitrate 4000000 dsample-point 0.800
- dtq 12 dprop-seg 7 dphase-seg1 8 dphase-seg2 4 dsjw 1
- pcan_usb_pro_fd: dtseg1 1..16 dtseg2 1..8 dsjw 1..4 dbrp 1..1024 \
- dbrp-inc 1
- clock 80000000
-
- Example when 'fd-non-iso on' is added on this switchable CAN FD adapter:
- can <FD,FD-NON-ISO> state ERROR-ACTIVE (berr-counter tx 0 rx 0) restart-ms 0
-

+===============================================
+XFRM device - offloading the IPsec computations
+===============================================
+Shannon Nelson <shannon.nelson@oracle.com>
+
+
+Overview
+========
+
+IPsec is a useful feature for securing network traffic, but the
+computational cost is high: a 10Gbps link can easily be brought down
+to under 1Gbps, depending on the traffic and link configuration.
+Luckily, there are NICs that offer a hardware based IPsec offload which
+can radically increase throughput and decrease CPU utilization. The XFRM
+Device interface allows NIC drivers to offer to the stack access to the
+hardware offload.
+
+Userland access to the offload is typically through a system such as
+libreswan or KAME/raccoon, but the iproute2 'ip xfrm' command set can
+be handy when experimenting. An example command might look something
+like this:
+
+ ip x s add proto esp dst 14.0.0.70 src 14.0.0.52 spi 0x07 mode transport \
+ reqid 0x07 replay-window 32 \
+ aead 'rfc4106(gcm(aes))' 0x44434241343332312423222114131211f4f3f2f1 128 \
+ sel src 14.0.0.52/24 dst 14.0.0.70/24 proto tcp \
+ offload dev eth4 dir in
+
+Yes, that's ugly, but that's what shell scripts and/or libreswan are for.
+
+
+
+Callbacks to implement
+======================
+
+/* from include/linux/netdevice.h */
+struct xfrmdev_ops {
+ int (*xdo_dev_state_add) (struct xfrm_state *x);
+ void (*xdo_dev_state_delete) (struct xfrm_state *x);
+ void (*xdo_dev_state_free) (struct xfrm_state *x);
+ bool (*xdo_dev_offload_ok) (struct sk_buff *skb,
+ struct xfrm_state *x);
+ void (*xdo_dev_state_advance_esn) (struct xfrm_state *x);
+};
+
+The NIC driver offering ipsec offload will need to implement these
+callbacks to make the offload available to the network stack's
+XFRM subsytem. Additionally, the feature bits NETIF_F_HW_ESP and
+NETIF_F_HW_ESP_TX_CSUM will signal the availability of the offload.
+
+
+
+Flow
+====
+
+At probe time and before the call to register_netdev(), the driver should
+set up local data structures and XFRM callbacks, and set the feature bits.
+The XFRM code's listener will finish the setup on NETDEV_REGISTER.
+
+ adapter->netdev->xfrmdev_ops = &ixgbe_xfrmdev_ops;
+ adapter->netdev->features |= NETIF_F_HW_ESP;
+ adapter->netdev->hw_enc_features |= NETIF_F_HW_ESP;
+
+When new SAs are set up with a request for "offload" feature, the
+driver's xdo_dev_state_add() will be given the new SA to be offloaded
+and an indication of whether it is for Rx or Tx. The driver should
+ - verify the algorithm is supported for offloads
+ - store the SA information (key, salt, target-ip, protocol, etc)
+ - enable the HW offload of the SA
+
+The driver can also set an offload_handle in the SA, an opaque void pointer
+that can be used to convey context into the fast-path offload requests.
+
+ xs->xso.offload_handle = context;
+
+
+When the network stack is preparing an IPsec packet for an SA that has
+been setup for offload, it first calls into xdo_dev_offload_ok() with
+the skb and the intended offload state to ask the driver if the offload
+will serviceable. This can check the packet information to be sure the
+offload can be supported (e.g. IPv4 or IPv6, no IPv4 options, etc) and
+return true of false to signify its support.
+
+When ready to send, the driver needs to inspect the Tx packet for the
+offload information, including the opaque context, and set up the packet
+send accordingly.
+
+ xs = xfrm_input_state(skb);
+ context = xs->xso.offload_handle;
+ set up HW for send
+
+The stack has already inserted the appropriate IPsec headers in the
+packet data, the offload just needs to do the encryption and fix up the
+header values.
+
+
+When a packet is received and the HW has indicated that it offloaded a
+decryption, the driver needs to add a reference to the decoded SA into
+the packet's skb. At this point the data should be decrypted but the
+IPsec headers are still in the packet data; they are removed later up
+the stack in xfrm_input().
+
+ find and hold the SA that was used to the Rx skb
+ get spi, protocol, and destination IP from packet headers
+ xs = find xs from (spi, protocol, dest_IP)
+ xfrm_state_hold(xs);
+
+ store the state information into the skb
+ skb->sp = secpath_dup(skb->sp);
+ skb->sp->xvec[skb->sp->len++] = xs;
+ skb->sp->olen++;
+
+ indicate the success and/or error status of the offload
+ xo = xfrm_offload(skb);
+ xo->flags = CRYPTO_DONE;
+ xo->status = crypto_status;
+
+ hand the packet to napi_gro_receive() as usual
+
+In ESN mode, xdo_dev_state_advance_esn() is called from xfrm_replay_advance_esn().
+Driver will check packet seq number and update HW ESN state machine if needed.
+
+When the SA is removed by the user, the driver's xdo_dev_state_delete()
+is asked to disable the offload. Later, xdo_dev_state_free() is called
+from a garbage collection routine after all reference counts to the state
+have been removed and any remaining resources can be cleared for the
+offload state. How these are used by the driver will depend on specific
+hardware needs.
+
+As a netdev is set to DOWN the XFRM stack's netdev listener will call
+xdo_dev_state_delete() and xdo_dev_state_free() on any remaining offloaded
+states.

+ARM DynamIQ Shared Unit (DSU) PMU
+==================================
+
+ARM DynamIQ Shared Unit integrates one or more cores with an L3 memory system,
+control logic and external interfaces to form a multicore cluster. The PMU
+allows counting the various events related to the L3 cache, Snoop Control Unit
+etc, using 32bit independent counters. It also provides a 64bit cycle counter.
+
+The PMU can only be accessed via CPU system registers and are common to the
+cores connected to the same DSU. Like most of the other uncore PMUs, DSU
+PMU doesn't support process specific events and cannot be used in sampling mode.
+
+The DSU provides a bitmap for a subset of implemented events via hardware
+registers. There is no way for the driver to determine if the other events
+are available or not. Hence the driver exposes only those events advertised
+by the DSU, in "events" directory under :
+
+ /sys/bus/event_sources/devices/arm_dsu_<N>/
+
+The user should refer to the TRM of the product to figure out the supported events
+and use the raw event code for the unlisted events.
+
+The driver also exposes the CPUs connected to the DSU instance in "associated_cpus".
+
+
+e.g usage :
+
+ perf stat -a -e arm_dsu_0/cycles/

-How to get printk format specifiers right
-=========================================
-
-:Author: Randy Dunlap <rdunlap@infradead.org>
-:Author: Andrew Murray <amurray@mpc-data.co.uk>
-
-Integer types
-=============
-
-::
-
- If variable is of Type, use printk format specifier:
- ------------------------------------------------------------
- int %d or %x
- unsigned int %u or %x
- long %ld or %lx
- unsigned long %lu or %lx
- long long %lld or %llx
- unsigned long long %llu or %llx
- size_t %zu or %zx
- ssize_t %zd or %zx
- s32 %d or %x
- u32 %u or %x
- s64 %lld or %llx
- u64 %llu or %llx
-
-If <type> is dependent on a config option for its size (e.g., ``sector_t``,
-``blkcnt_t``) or is architecture-dependent for its size (e.g., ``tcflag_t``),
-use a format specifier of its largest possible type and explicitly cast to it.
-
-Example::
-
- printk("test: sector number/total blocks: %llu/%llu\n",
- (unsigned long long)sector, (unsigned long long)blockcount);
-
-Reminder: ``sizeof()`` result is of type ``size_t``.
-
-The kernel's printf does not support ``%n``. For obvious reasons, floating
-point formats (``%e, %f, %g, %a``) are also not recognized. Use of any
-unsupported specifier or length qualifier results in a WARN and early
-return from vsnprintf.
-
-Raw pointer value SHOULD be printed with %p. The kernel supports
-the following extended format specifiers for pointer types:
-
-Pointer Types
-=============
-
-Pointers printed without a specifier extension (i.e unadorned %p) are
-hashed to give a unique identifier without leaking kernel addresses to user
-space. On 64 bit machines the first 32 bits are zeroed. If you _really_
-want the address see %px below.
-
-::
-
- %p abcdef12 or 00000000abcdef12
-
-Symbols/Function Pointers
-=========================
-
-::
-
- %pF versatile_init+0x0/0x110
- %pf versatile_init
- %pS versatile_init+0x0/0x110
- %pSR versatile_init+0x9/0x110
- (with __builtin_extract_return_addr() translation)
- %ps versatile_init
- %pB prev_fn_of_versatile_init+0x88/0x88
-
-The ``F`` and ``f`` specifiers are for printing function pointers,
-for example, f->func, &gettimeofday. They have the same result as
-``S`` and ``s`` specifiers. But they do an extra conversion on
-ia64, ppc64 and parisc64 architectures where the function pointers
-are actually function descriptors.
-
-The ``S`` and ``s`` specifiers can be used for printing symbols
-from direct addresses, for example, __builtin_return_address(0),
-(void *)regs->ip. They result in the symbol name with (``S``) or
-without (``s``) offsets. If KALLSYMS are disabled then the symbol
-address is printed instead.
-
-The ``B`` specifier results in the symbol name with offsets and should be
-used when printing stack backtraces. The specifier takes into
-consideration the effect of compiler optimisations which may occur
-when tail-call``s are used and marked with the noreturn GCC attribute.
-
-Examples::
-
- printk("Going to call: %pF\n", gettimeofday);
- printk("Going to call: %pF\n", p->func);
- printk("%s: called from %pS\n", __func__, (void *)_RET_IP_);
- printk("%s: called from %pS\n", __func__,
- (void *)__builtin_return_address(0));
- printk("Faulted at %pS\n", (void *)regs->ip);
- printk(" %s%pB\n", (reliable ? "" : "? "), (void *)*stack);
-
-Kernel Pointers
-===============
-
-::
-
- %pK 01234567 or 0123456789abcdef
-
-For printing kernel pointers which should be hidden from unprivileged
-users. The behaviour of ``%pK`` depends on the ``kptr_restrict sysctl`` - see
-Documentation/sysctl/kernel.txt for more details.
-
-Unmodified Addresses
-====================
-
-::
-
- %px 01234567 or 0123456789abcdef
-
-For printing pointers when you _really_ want to print the address. Please
-consider whether or not you are leaking sensitive information about the
-Kernel layout in memory before printing pointers with %px. %px is
-functionally equivalent to %lx. %px is preferred to %lx because it is more
-uniquely grep'able. If, in the future, we need to modify the way the Kernel
-handles printing pointers it will be nice to be able to find the call
-sites.
-
-Struct Resources
-================
-
-::
-
- %pr [mem 0x60000000-0x6fffffff flags 0x2200] or
- [mem 0x0000000060000000-0x000000006fffffff flags 0x2200]
- %pR [mem 0x60000000-0x6fffffff pref] or
- [mem 0x0000000060000000-0x000000006fffffff pref]
-
-For printing struct resources. The ``R`` and ``r`` specifiers result in a
-printed resource with (``R``) or without (``r``) a decoded flags member.
-Passed by reference.
-
-Physical addresses types ``phys_addr_t``
-========================================
-
-::
-
- %pa[p] 0x01234567 or 0x0123456789abcdef
-
-For printing a ``phys_addr_t`` type (and its derivatives, such as
-``resource_size_t``) which can vary based on build options, regardless of
-the width of the CPU data path. Passed by reference.
-
-DMA addresses types ``dma_addr_t``
-==================================
-
-::
-
- %pad 0x01234567 or 0x0123456789abcdef
-
-For printing a ``dma_addr_t`` type which can vary based on build options,
-regardless of the width of the CPU data path. Passed by reference.
-
-Raw buffer as an escaped string
-===============================
-
-::
-
- %*pE[achnops]
-
-For printing raw buffer as an escaped string. For the following buffer::
-
- 1b 62 20 5c 43 07 22 90 0d 5d
-
-few examples show how the conversion would be done (the result string
-without surrounding quotes)::
-
- %*pE "\eb \C\a"\220\r]"
- %*pEhp "\x1bb \C\x07"\x90\x0d]"
- %*pEa "\e\142\040\\\103\a\042\220\r\135"
-
-The conversion rules are applied according to an optional combination
-of flags (see :c:func:`string_escape_mem` kernel documentation for the
-details):
-
- - ``a`` - ESCAPE_ANY
- - ``c`` - ESCAPE_SPECIAL
- - ``h`` - ESCAPE_HEX
- - ``n`` - ESCAPE_NULL
- - ``o`` - ESCAPE_OCTAL
- - ``p`` - ESCAPE_NP
- - ``s`` - ESCAPE_SPACE
-
-By default ESCAPE_ANY_NP is used.
-
-ESCAPE_ANY_NP is the sane choice for many cases, in particularly for
-printing SSIDs.
-
-If field width is omitted the 1 byte only will be escaped.
-
-Raw buffer as a hex string
-==========================
-
-::
-
- %*ph 00 01 02 ... 3f
- %*phC 00:01:02: ... :3f
- %*phD 00-01-02- ... -3f
- %*phN 000102 ... 3f
-
-For printing a small buffers (up to 64 bytes long) as a hex string with
-certain separator. For the larger buffers consider to use
-:c:func:`print_hex_dump`.
-
-MAC/FDDI addresses
-==================
-
-::
-
- %pM 00:01:02:03:04:05
- %pMR 05:04:03:02:01:00
- %pMF 00-01-02-03-04-05
- %pm 000102030405
- %pmR 050403020100
-
-For printing 6-byte MAC/FDDI addresses in hex notation. The ``M`` and ``m``
-specifiers result in a printed address with (``M``) or without (``m``) byte
-separators. The default byte separator is the colon (``:``).
-
-Where FDDI addresses are concerned the ``F`` specifier can be used after
-the ``M`` specifier to use dash (``-``) separators instead of the default
-separator.
-
-For Bluetooth addresses the ``R`` specifier shall be used after the ``M``
-specifier to use reversed byte order suitable for visual interpretation
-of Bluetooth addresses which are in the little endian order.
-
-Passed by reference.
-
-IPv4 addresses
-==============
-
-::
-
- %pI4 1.2.3.4
- %pi4 001.002.003.004
- %p[Ii]4[hnbl]
-
-For printing IPv4 dot-separated decimal addresses. The ``I4`` and ``i4``
-specifiers result in a printed address with (``i4``) or without (``I4``)
-leading zeros.
-
-The additional ``h``, ``n``, ``b``, and ``l`` specifiers are used to specify
-host, network, big or little endian order addresses respectively. Where
-no specifier is provided the default network/big endian order is used.
-
-Passed by reference.
-
-IPv6 addresses
-==============
-
-::
-
- %pI6 0001:0002:0003:0004:0005:0006:0007:0008
- %pi6 00010002000300040005000600070008
- %pI6c 1:2:3:4:5:6:7:8
-
-For printing IPv6 network-order 16-bit hex addresses. The ``I6`` and ``i6``
-specifiers result in a printed address with (``I6``) or without (``i6``)
-colon-separators. Leading zeros are always used.
-
-The additional ``c`` specifier can be used with the ``I`` specifier to
-print a compressed IPv6 address as described by
-http://tools.ietf.org/html/rfc5952
-
-Passed by reference.
-
-IPv4/IPv6 addresses (generic, with port, flowinfo, scope)
-=========================================================
-
-::
-
- %pIS 1.2.3.4 or 0001:0002:0003:0004:0005:0006:0007:0008
- %piS 001.002.003.004 or 00010002000300040005000600070008
- %pISc 1.2.3.4 or 1:2:3:4:5:6:7:8
- %pISpc 1.2.3.4:12345 or [1:2:3:4:5:6:7:8]:12345
- %p[Ii]S[pfschnbl]
-
-For printing an IP address without the need to distinguish whether it``s
-of type AF_INET or AF_INET6, a pointer to a valid ``struct sockaddr``,
-specified through ``IS`` or ``iS``, can be passed to this format specifier.
-
-The additional ``p``, ``f``, and ``s`` specifiers are used to specify port
-(IPv4, IPv6), flowinfo (IPv6) and scope (IPv6). Ports have a ``:`` prefix,
-flowinfo a ``/`` and scope a ``%``, each followed by the actual value.
-
-In case of an IPv6 address the compressed IPv6 address as described by
-http://tools.ietf.org/html/rfc5952 is being used if the additional
-specifier ``c`` is given. The IPv6 address is surrounded by ``[``, ``]`` in
-case of additional specifiers ``p``, ``f`` or ``s`` as suggested by
-https://tools.ietf.org/html/draft-ietf-6man-text-addr-representation-07
-
-In case of IPv4 addresses, the additional ``h``, ``n``, ``b``, and ``l``
-specifiers can be used as well and are ignored in case of an IPv6
-address.
-
-Passed by reference.
-
-Further examples::
-
- %pISfc 1.2.3.4 or [1:2:3:4:5:6:7:8]/123456789
- %pISsc 1.2.3.4 or [1:2:3:4:5:6:7:8]%1234567890
- %pISpfc 1.2.3.4:12345 or [1:2:3:4:5:6:7:8]:12345/123456789
-
-UUID/GUID addresses
-===================
-
-::
-
- %pUb 00010203-0405-0607-0809-0a0b0c0d0e0f
- %pUB 00010203-0405-0607-0809-0A0B0C0D0E0F
- %pUl 03020100-0504-0706-0809-0a0b0c0e0e0f
- %pUL 03020100-0504-0706-0809-0A0B0C0E0E0F
-
-For printing 16-byte UUID/GUIDs addresses. The additional 'l', 'L',
-'b' and 'B' specifiers are used to specify a little endian order in
-lower ('l') or upper case ('L') hex characters - and big endian order
-in lower ('b') or upper case ('B') hex characters.
-
-Where no additional specifiers are used the default big endian
-order with lower case hex characters will be printed.
-
-Passed by reference.
-
-dentry names
-============
-
-::
-
- %pd{,2,3,4}
- %pD{,2,3,4}
-
-For printing dentry name; if we race with :c:func:`d_move`, the name might be
-a mix of old and new ones, but it won't oops. ``%pd`` dentry is a safer
-equivalent of ``%s`` ``dentry->d_name.name`` we used to use, ``%pd<n>`` prints
-``n`` last components. ``%pD`` does the same thing for struct file.
-
-Passed by reference.
-
-block_device names
-==================
-
-::
-
- %pg sda, sda1 or loop0p1
-
-For printing name of block_device pointers.
-
-struct va_format
-================
-
-::
-
- %pV
-
-For printing struct va_format structures. These contain a format string
-and va_list as follows::
-
- struct va_format {
- const char *fmt;
- va_list *va;
- };
-
-Implements a "recursive vsnprintf".
-
-Do not use this feature without some mechanism to verify the
-correctness of the format string and va_list arguments.
-
-Passed by reference.
-
-kobjects
-========
-
-::
-
- %pO
-
- Base specifier for kobject based structs. Must be followed with
- character for specific type of kobject as listed below:
-
- Device tree nodes:
-
- %pOF[fnpPcCF]
-
- For printing device tree nodes. The optional arguments are:
- f device node full_name
- n device node name
- p device node phandle
- P device node path spec (name + @unit)
- F device node flags
- c major compatible string
- C full compatible string
- Without any arguments prints full_name (same as %pOFf)
- The separator when using multiple arguments is ':'
-
- Examples:
-
- %pOF /foo/bar@0 - Node full name
- %pOFf /foo/bar@0 - Same as above
- %pOFfp /foo/bar@0:10 - Node full name + phandle
- %pOFfcF /foo/bar@0:foo,device:--P- - Node full name +
- major compatible string +
- node flags
- D - dynamic
- d - detached
- P - Populated
- B - Populated bus
-
- Passed by reference.
-
-
-struct clk
-==========
-
-::
-
- %pC pll1
- %pCn pll1
- %pCr 1560000000
-
-For printing struct clk structures. ``%pC`` and ``%pCn`` print the name
-(Common Clock Framework) or address (legacy clock framework) of the
-structure; ``%pCr`` prints the current clock rate.
-
-Passed by reference.
-
-bitmap and its derivatives such as cpumask and nodemask
-=======================================================
-
-::
-
- %*pb 0779
- %*pbl 0,3-6,8-10
-
-For printing bitmap and its derivatives such as cpumask and nodemask,
-``%*pb`` output the bitmap with field width as the number of bits and ``%*pbl``
-output the bitmap as range list with field width as the number of bits.
-
-Passed by reference.
-
-Flags bitfields such as page flags, gfp_flags
-=============================================
-
-::
-
- %pGp referenced|uptodate|lru|active|private
- %pGg GFP_USER|GFP_DMA32|GFP_NOWARN
- %pGv read|exec|mayread|maywrite|mayexec|denywrite
-
-For printing flags bitfields as a collection of symbolic constants that
-would construct the value. The type of flags is given by the third
-character. Currently supported are [p]age flags, [v]ma_flags (both
-expect ``unsigned long *``) and [g]fp_flags (expects ``gfp_t *``). The flag
-names and print order depends on the particular type.
-
-Note that this format should not be used directly in :c:func:`TP_printk()` part
-of a tracepoint. Instead, use the ``show_*_flags()`` functions from
-<trace/events/mmflags.h>.
-
-Passed by reference.
-
-Network device features
-=======================
-
-::
-
- %pNF 0x000000000000c000
-
-For printing netdev_features_t.
-
-Passed by reference.
-
-If you add other ``%p`` extensions, please extend lib/test_printf.c with
-one or more test cases, if at all feasible.
-
-
-Thank you for your cooperation and attention.

+Linux kernel licensing rules
+============================
+
+The Linux Kernel is provided under the terms of the GNU General Public
+License version 2 only (GPL-2.0), as published by the Free Software
+Foundation, and provided in the COPYING file. This documentation file is
+not meant to replace the COPYING file, but provides a description of how
+each source file should be annotated to make the licensing it is governed
+under clear and unambiguous.
+
+The license in the COPYING file applies to the kernel source as a whole,
+though individual source files can have a different license which is
+required to be compatible with the GPL-2.0::
+
+ GPL-1.0+ : GNU General Public License v1.0 or later
+ GPL-2.0+ : GNU General Public License v2.0 or later
+ LGPL-2.0 : GNU Library General Public License v2 only
+ LGPL-2.0+ : GNU Library General Public License v2 or later
+ LGPL-2.1 : GNU Lesser General Public License v2.1 only
+ LGPL-2.1+ : GNU Lesser General Public License v2.1 or later
+
+Aside from that, individual files can be provided under a dual license,
+e.g. one of the compatible GPL variants and alternatively under a
+permissive license like BSD, MIT etc.
+
+The User-space API (UAPI) header files, which describe the interface of
+user-space programs to the kernel are a special case. According to the
+note in the kernel COPYING file, the syscall interface is a clear boundary,
+which does not extend the GPL requirements to any software which uses it to
+communicate with the kernel. Because the UAPI headers must be includable
+into any source files which create an executable running on the Linux
+kernel, the exception must be documented by a special license expression.
+
+The common way of expressing the license of a source file is to add the
+matching boilerplate text into the top comment of the file. Due to
+formatting, typos etc. these "boilerplates" are hard to validate for
+tools which are used in the context of license compliance.
+
+An alternative to boilerplate text is the use of Software Package Data
+Exchange (SPDX) license identifiers in each source file. SPDX license
+identifiers are machine parsable and precise shorthands for the license
+under which the content of the file is contributed. SPDX license
+identifiers are managed by the SPDX Workgroup at the Linux Foundation and
+have been agreed on by partners throughout the industry, tool vendors, and
+legal teams. For further information see https://spdx.org/
+
+The Linux kernel requires the precise SPDX identifier in all source files.
+The valid identifiers used in the kernel are explained in the section
+`License identifiers`_ and have been retrieved from the official SPDX
+license list at https://spdx.org/licenses/ along with the license texts.
+
+License identifier syntax
+-------------------------
+
+1. Placement:
+
+ The SPDX license identifier in kernel files shall be added at the first
+ possible line in a file which can contain a comment. For the majority
+ or files this is the first line, except for scripts which require the
+ '#!PATH_TO_INTERPRETER' in the first line. For those scripts the SPDX
+ identifier goes into the second line.
+
+|
+
+2. Style:
+
+ The SPDX license identifier is added in form of a comment. The comment
+ style depends on the file type::
+
+ C source: // SPDX-License-Identifier: <SPDX License Expression>
+ C header: /* SPDX-License-Identifier: <SPDX License Expression> */
+ ASM: /* SPDX-License-Identifier: <SPDX License Expression> */
+ scripts: # SPDX-License-Identifier: <SPDX License Expression>
+ .rst: .. SPDX-License-Identifier: <SPDX License Expression>
+ .dts{i}: // SPDX-License-Identifier: <SPDX License Expression>
+
+ If a specific tool cannot handle the standard comment style, then the
+ appropriate comment mechanism which the tool accepts shall be used. This
+ is the reason for having the "/\* \*/" style comment in C header
+ files. There was build breakage observed with generated .lds files where
+ 'ld' failed to parse the C++ comment. This has been fixed by now, but
+ there are still older assembler tools which cannot handle C++ style
+ comments.
+
+|
+
+3. Syntax:
+
+ A <SPDX License Expression> is either an SPDX short form license
+ identifier found on the SPDX License List, or the combination of two
+ SPDX short form license identifiers separated by "WITH" when a license
+ exception applies. When multiple licenses apply, an expression consists
+ of keywords "AND", "OR" separating sub-expressions and surrounded by
+ "(", ")" .
+
+ License identifiers for licenses like [L]GPL with the 'or later' option
+ are constructed by using a "+" for indicating the 'or later' option.::
+
+ // SPDX-License-Identifier: GPL-2.0+
+ // SPDX-License-Identifier: LGPL-2.1+
+
+ WITH should be used when there is a modifier to a license needed.
+ For example, the linux kernel UAPI files use the expression::
+
+ // SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note
+ // SPDX-License-Identifier: GPL-2.0+ WITH Linux-syscall-note
+
+ Other examples using WITH exceptions found in the kernel are::
+
+ // SPDX-License-Identifier: GPL-2.0 WITH mif-exception
+ // SPDX-License-Identifier: GPL-2.0+ WITH GCC-exception-2.0
+
+ Exceptions can only be used with particular License identifiers. The
+ valid License identifiers are listed in the tags of the exception text
+ file. For details see the point `Exceptions`_ in the chapter `License
+ identifiers`_.
+
+ OR should be used if the file is dual licensed and only one license is
+ to be selected. For example, some dtsi files are available under dual
+ licenses::
+
+ // SPDX-License-Identifier: GPL-2.0 OR BSD-3-Clause
+
+ Examples from the kernel for license expressions in dual licensed files::
+
+ // SPDX-License-Identifier: GPL-2.0 OR MIT
+ // SPDX-License-Identifier: GPL-2.0 OR BSD-2-Clause
+ // SPDX-License-Identifier: GPL-2.0 OR Apache-2.0
+ // SPDX-License-Identifier: GPL-2.0 OR MPL-1.1
+ // SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) OR MIT
+ // SPDX-License-Identifier: GPL-1.0+ OR BSD-3-Clause OR OpenSSL
+
+ AND should be used if the file has multiple licenses whose terms all
+ apply to use the file. For example, if code is inherited from another
+ project and permission has been given to put it in the kernel, but the
+ original license terms need to remain in effect::
+
+ // SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) AND MIT
+
+ Another other example where both sets of license terms need to be
+ adhered to is::
+
+ // SPDX-License-Identifier: GPL-1.0+ AND LGPL-2.1+
+
+License identifiers
+-------------------
+
+The licenses currently used, as well as the licenses for code added to the
+kernel, can be broken down into:
+
+1. _`Preferred licenses`:
+
+ Whenever possible these licenses should be used as they are known to be
+ fully compatible and widely used. These licenses are available from the
+ directory::
+
+ LICENSES/preferred/
+
+ in the kernel source tree.
+
+ The files in this directory contain the full license text and
+ `Metatags`_. The file names are identical to the SPDX license
+ identifier which shall be used for the license in source files.
+
+ Examples::
+
+ LICENSES/preferred/GPL-2.0
+
+ Contains the GPL version 2 license text and the required metatags::
+
+ LICENSES/preferred/MIT
+
+ Contains the MIT license text and the required metatags
+
+ _`Metatags`:
+
+ The following meta tags must be available in a license file:
+
+ - Valid-License-Identifier:
+
+ One or more lines which declare which License Identifiers are valid
+ inside the project to reference this particular license text. Usually
+ this is a single valid identifier, but e.g. for licenses with the 'or
+ later' options two identifiers are valid.
+
+ - SPDX-URL:
+
+ The URL of the SPDX page which contains additional information related
+ to the license.
+
+ - Usage-Guidance:
+
+ Freeform text for usage advice. The text must include correct examples
+ for the SPDX license identifiers as they should be put into source
+ files according to the `License identifier syntax`_ guidelines.
+
+ - License-Text:
+
+ All text after this tag is treated as the original license text
+
+ File format examples::
+
+ Valid-License-Identifier: GPL-2.0
+ Valid-License-Identifier: GPL-2.0+
+ SPDX-URL: https://spdx.org/licenses/GPL-2.0.html
+ Usage-Guide:
+ To use this license in source code, put one of the following SPDX
+ tag/value pairs into a comment according to the placement
+ guidelines in the licensing rules documentation.
+ For 'GNU General Public License (GPL) version 2 only' use:
+ SPDX-License-Identifier: GPL-2.0
+ For 'GNU General Public License (GPL) version 2 or any later version' use:
+ SPDX-License-Identifier: GPL-2.0+
+ License-Text:
+ Full license text
+
+ ::
+
+ SPDX-License-Identifier: MIT
+ SPDX-URL: https://spdx.org/licenses/MIT.html
+ Usage-Guide:
+ To use this license in source code, put the following SPDX
+ tag/value pair into a comment according to the placement
+ guidelines in the licensing rules documentation.
+ SPDX-License-Identifier: MIT
+ License-Text:
+ Full license text
+
+|
+
+2. Not recommended licenses:
+
+ These licenses should only be used for existing code or for importing
+ code from a different project. These licenses are available from the
+ directory::
+
+ LICENSES/other/
+
+ in the kernel source tree.
+
+ The files in this directory contain the full license text and
+ `Metatags`_. The file names are identical to the SPDX license
+ identifier which shall be used for the license in source files.
+
+ Examples::
+
+ LICENSES/other/ISC
+
+ Contains the Internet Systems Consortium license text and the required
+ metatags::
+
+ LICENSES/other/ZLib
+
+ Contains the ZLIB license text and the required metatags.
+
+ Metatags:
+
+ The metatag requirements for 'other' licenses are identical to the
+ requirements of the `Preferred licenses`_.
+
+ File format example::
+
+ Valid-License-Identifier: ISC
+ SPDX-URL: https://spdx.org/licenses/ISC.html
+ Usage-Guide:
+ Usage of this license in the kernel for new code is discouraged
+ and it should solely be used for importing code from an already
+ existing project.
+ To use this license in source code, put the following SPDX
+ tag/value pair into a comment according to the placement
+ guidelines in the licensing rules documentation.
+ SPDX-License-Identifier: ISC
+ License-Text:
+ Full license text
+
+|
+
+3. _`Exceptions`:
+
+ Some licenses can be amended with exceptions which grant certain rights
+ which the original license does not. These exceptions are available
+ from the directory::
+
+ LICENSES/exceptions/
+
+ in the kernel source tree. The files in this directory contain the full
+ exception text and the required `Exception Metatags`_.
+
+ Examples::
+
+ LICENSES/exceptions/Linux-syscall-note
+
+ Contains the Linux syscall exception as documented in the COPYING
+ file of the Linux kernel, which is used for UAPI header files.
+ e.g. /\* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note \*/::
+
+ LICENSES/exceptions/GCC-exception-2.0
+
+ Contains the GCC 'linking exception' which allows to link any binary
+ independent of its license against the compiled version of a file marked
+ with this exception. This is required for creating runnable executables
+ from source code which is not compatible with the GPL.
+
+ _`Exception Metatags`:
+
+ The following meta tags must be available in an exception file:
+
+ - SPDX-Exception-Identifier:
+
+ One exception identifier which can be used with SPDX license
+ identifiers.
+
+ - SPDX-URL:
+
+ The URL of the SPDX page which contains additional information related
+ to the exception.
+
+ - SPDX-Licenses:
+
+ A comma separated list of SPDX license identifiers for which the
+ exception can be used.
+
+ - Usage-Guidance:
+
+ Freeform text for usage advice. The text must be followed by correct
+ examples for the SPDX license identifiers as they should be put into
+ source files according to the `License identifier syntax`_ guidelines.
+
+ - Exception-Text:
+
+ All text after this tag is treated as the original exception text
+
+ File format examples::
+
+ SPDX-Exception-Identifier: Linux-syscall-note
+ SPDX-URL: https://spdx.org/licenses/Linux-syscall-note.html
+ SPDX-Licenses: GPL-2.0, GPL-2.0+, GPL-1.0+, LGPL-2.0, LGPL-2.0+, LGPL-2.1, LGPL-2.1+
+ Usage-Guidance:
+ This exception is used together with one of the above SPDX-Licenses
+ to mark user-space API (uapi) header files so they can be included
+ into non GPL compliant user-space application code.
+ To use this exception add it with the keyword WITH to one of the
+ identifiers in the SPDX-Licenses tag:
+ SPDX-License-Identifier: <SPDX-License> WITH Linux-syscall-note
+ Exception-Text:
+ Full exception text
+
+ ::
+
+ SPDX-Exception-Identifier: GCC-exception-2.0
+ SPDX-URL: https://spdx.org/licenses/GCC-exception-2.0.html
+ SPDX-Licenses: GPL-2.0, GPL-2.0+
+ Usage-Guidance:
+ The "GCC Runtime Library exception 2.0" is used together with one
+ of the above SPDX-Licenses for code imported from the GCC runtime
+ library.
+ To use this exception add it with the keyword WITH to one of the
+ identifiers in the SPDX-Licenses tag:
+ SPDX-License-Identifier: <SPDX-License> WITH GCC-exception-2.0
+ Exception-Text:
+ Full exception text
+
+
+All SPDX license identifiers and exceptions must have a corresponding file
+in the LICENSE subdirectories. This is required to allow tool
+verification (e.g. checkpatch.pl) and to have the licenses ready to read
+and extract right from the source, which is recommended by various FOSS
+organizations, e.g. the `FSFE REUSE initiative <https://reuse.software/>`_.

-*/nvmem The non volatile storage exported as a raw file, as described
- in Documentation/nvmem/nvmem.txt
-================ ==============================================================
-
-IOCTL interface
----------------
-
-The ioctl() calls supported by /dev/rtc are also supported by the RTC class
-framework. However, because the chips and systems are not standardized,
-some PC/AT functionality might not be provided. And in the same way, some
-newer features -- including those enabled by ACPI -- are exposed by the
-RTC class framework, but can't be supported by the older driver.
-
- * RTC_RD_TIME, RTC_SET_TIME ... every RTC supports at least reading
- time, returning the result as a Gregorian calendar date and 24 hour
- wall clock time. To be most useful, this time may also be updated.
-
- * RTC_AIE_ON, RTC_AIE_OFF, RTC_ALM_SET, RTC_ALM_READ ... when the RTC
- is connected to an IRQ line, it can often issue an alarm IRQ up to
- 24 hours in the future. (Use RTC_WKALM_* by preference.)
-
- * RTC_WKALM_SET, RTC_WKALM_RD ... RTCs that can issue alarms beyond
- the next 24 hours use a slightly more powerful API, which supports
- setting the longer alarm time and enabling its IRQ using a single
- request (using the same model as EFI firmware).
-
- * RTC_UIE_ON, RTC_UIE_OFF ... if the RTC offers IRQs, the RTC framework
- will emulate this mechanism.
-
- * RTC_PIE_ON, RTC_PIE_OFF, RTC_IRQP_SET, RTC_IRQP_READ ... these icotls
- are emulated via a kernel hrtimer.
-
-In many cases, the RTC alarm can be a system wake event, used to force
-Linux out of a low power sleep state (or hibernation) back to a fully
-operational state. For example, a system could enter a deep power saving
-state until it's time to execute some scheduled tasks.
-
-Note that many of these ioctls are handled by the common rtc-dev interface.
-Some common examples:
-
- * RTC_RD_TIME, RTC_SET_TIME: the read_time/set_time functions will be
- called with appropriate values.
-
- * RTC_ALM_SET, RTC_ALM_READ, RTC_WKALM_SET, RTC_WKALM_RD: gets or sets
- the alarm rtc_timer. May call the set_alarm driver function.
-
- * RTC_IRQP_SET, RTC_IRQP_READ: These are emulated by the generic code.

+Chapter 36. Coprocessor services
+ The following APIs provide access via the Hypervisor to hardware assisted data processing functionality.
+ These APIs may only be provided by certain platforms, and may not be available to all virtual machines
+ even on supported platforms. Restrictions on the use of these APIs may be imposed in order to support
+ live-migration and other system management activities.
+
+36.1. Data Analytics Accelerator
+ The Data Analytics Accelerator (DAX) functionality is a collection of hardware coprocessors that provide
+ high speed processoring of database-centric operations. The coprocessors may support one or more of
+ the following data query operations: search, extraction, compression, decompression, and translation. The
+ functionality offered may vary by virtual machine implementation.
+
+ The DAX is a virtual device to sun4v guests, with supported data operations indicated by the virtual device
+ compatibilty property. Functionality is accessed through the submission of Command Control Blocks
+ (CCBs) via the ccb_submit API function. The operations are processed asynchronously, with the status
+ of the submitted operations reported through a Completion Area linked to each CCB. Each CCB has a
+ separate Completion Area and, unless execution order is specifically restricted through the use of serial-
+ conditional flags, the execution order of submitted CCBs is arbitrary. Likewise, the time to completion
+ for a given CCB is never guaranteed.
+
+ Guest software may implement a software timeout on CCB operations, and if the timeout is exceeded, the
+ operation may be cancelled or killed via the ccb_kill API function. It is recommended for guest software
+ to implement a software timeout to account for certain RAS errors which may result in lost CCBs. It is
+ recommended such implementation use the ccb_info API function to check the status of a CCB prior to
+ killing it in order to determine if the CCB is still in queue, or may have been lost due to a RAS error.
+
+ There is no fixed limit on the number of outstanding CCBs guest software may have queued in the virtual
+ machine, however, internal resource limitations within the virtual machine can cause CCB submissions
+ to be temporarily rejected with EWOULDBLOCK. In such cases, guests should continue to attempt
+ submissions until they succeed; waiting for an outstanding CCB to complete is not necessary, and would
+ not be a guarantee that a future submission would succeed.
+
+ The availablility of DAX coprocessor command service is indicated by the presence of the DAX virtual
+ device node in the guest MD (Section 8.24.17, “Database Analytics Accelerators (DAX) virtual-device
+ node”).
+
+36.1.1. DAX Compatibility Property

+ Version 0 and 1 CCBs are available. Only version 0 CCBs may use Huffman encoded data, whereas only
+ version 1 CCBs may use OZIP.
+
+36.1.2. DAX Virtual Device Interrupts
+ The DAX virtual device has multiple interrupts associated with it which may be used by the guest if
+ desired. The number of device interrupts available to the guest is indicated in the virtual device node of the
+ guest MD (Section 8.24.17, “Database Analytics Accelerators (DAX) virtual-device node”). If the device
+ node indicates N interrupts available, the guest may use any value from 0 to N - 1 (inclusive) in a CCB
+ interrupt number field. Using values outside this range will result in the CCB being rejected for an invalid
+ field value.
+
+ The interrupts may be bound and managed using the standard sun4v device interrupts API (Chapter 16,
+ Device interrupt services). Sysino interrupts are not available for DAX devices.
+
+36.2. Coprocessor Control Block (CCB)
+ CCBs are either 64 or 128 bytes long, depending on the operation type. The exact contents of the CCB
+ are command specific, but all CCBs contain at least one memory buffer address. All memory locations
+
+
+ 510
+ Coprocessor services
+
+
+referenced by a CCB must be pinned in memory until the CCB either completes execution or is killed
+via the ccb_kill API call. Changes in virtual address mappings occurring after CCB submission are not
+guaranteed to be visible, and as such all virtual address updates need to be synchronized with CCB
+execution.
+
+All CCBs begin with a common 32-bit header.

+
+The Long CCB flag indicates whether the submitted CCB is 64 or 128 bytes long; value is 0 for 64 bytes
+and 1 for 128 bytes.
+
+The Serial and Conditional flags allow simple relative ordering between CCBs. Any CCB with the Serial
+flag set will execute sequentially relative to any previous CCB that is also marked as Serial in the same
+CCB submission. CCBs without the Serial flag set execute independently, even if they are between CCBs
+with the Serial flag set. CCBs marked solely with the Serial flag will execute upon the completion of the
+previous Serial CCB, regardless of the completion status of that CCB. The Conditional flag allows CCBs
+to conditionally execute based on the successful execution of the closest CCB marked with the Serial flag.
+A CCB may only be conditional on exactly one CCB, however, a CCB may be marked both Conditional
+and Serial to allow execution chaining. The flags do NOT allow fan-out chaining, where multiple CCBs
+execute in parallel based on the completion of another CCB.
+
+The Pipeline flag is an optimization that directs the output of one CCB (the "source" CCB) directly to
+the input of the next CCB (the "target" CCB). The target CCB thus does not need to read the input from
+memory. The Pipeline flag is advisory and may be dropped.
+
+Both the Pipeline and Serial bits must be set in the source CCB. The Conditional bit must be set in the
+target CCB. Exactly one CCB must be made conditional on the source CCB; either 0 or 2 target CCBs
+is invalid. However, Pipelines can be extended beyond two CCBs: the sequence would start with a CCB
+with both the Pipeline and Serial bits set, proceed through CCBs with the Pipeline, Serial, and Conditional
+bits set, and terminate at a CCB that has the Conditional bit set, but not the Pipeline bit.
+
+
+ 512
+ Coprocessor services
+
+
+ The input of the target CCB must start within 64 bytes of the output of the source CCB or the pipeline flag
+ will be ignored. All CCBs in a pipeline must be submitted in the same call to ccb_submit.
+
+ The various address type fields indicate how the various address values used in the CCB should be
+ interpreted by the virtual machine. Not all of the types specified are used by every CCB format. Types
+ which are not applicable to the given CCB command should be indicated as type 0 (No address). Virtual
+ addresses used in the CCB must have translation entries present in either the TLB or a configured TSB
+ for the submitting virtual processor. Virtual addresses which cannot be translated by the virtual machine
+ will result in the CCB submission being rejected, with the causal virtual address indicated. The CCB
+ may be resubmitted after inserting the translation, or the address may be translated by guest software and
+ resubmitted using the real address translation.
+
+36.2.1. Query CCB Command Formats
+36.2.1.1. Supported Data Formats, Elements Sizes and Offsets
+ Data for query commands may be encoded in multiple possible formats. The data query commands use a
+ common set of values to indicate the encoding formats of the data being processed. Some encoding formats
+ require multiple data streams for processing, requiring the specification of both primary data formats (the
+ encoded data) and secondary data streams (meta-data for the encoded data).
+
+36.2.1.1.1. Primary Input Format
+
+ The primary input format code is a 4-bit field when it is used. There are 10 primary input formats available.
+ The packed formats are not endian neutral. Code values not listed below are reserved.
+
+ Code Format Description
+ 0x0 Fixed width byte packed Up to 16 bytes
+ 0x1 Fixed width bit packed Up to 15 bits (CCB version 0) or 23 bits (CCB version
+ 1); bits are read most significant bit to least significant bit
+ within a byte
+ 0x2 Variable width byte packed Data stream of lengths must be provided as a secondary
+ input
+ 0x4 Fixed width byte packed with run Up to 16 bytes; data stream of run lengths must be
+ length encoding provided as a secondary input
+ 0x5 Fixed width bit packed with run Up to 15 bits (CCB version 0) or 23 bits (CCB version
+ length encoding 1); bits are read most significant bit to least significant bit
+ within a byte; data stream of run lengths must be provided
+ as a secondary input
+ 0x8 Fixed width byte packed with Up to 16 bytes before the encoding; compressed stream
+ Huffman (CCB version 0) or bits are read most significant bit to least significant bit
+ OZIP (CCB version 1) encoding within a byte; pointer to the encoding table must be
+ provided
+ 0x9 Fixed width bit packed with Up to 15 bits (CCB version 0) or 23 bits (CCB version
+ Huffman (CCB version 0) or 1); compressed stream bits are read most significant bit to
+ OZIP (CCB version 1) encoding least significant bit within a byte; pointer to the encoding
+ table must be provided
+ 0xA Variable width byte packed with Up to 16 bytes before the encoding; compressed stream
+ Huffman (CCB version 0) or bits are read most significant bit to least significant bit
+ OZIP (CCB version 1) encoding within a byte; data stream of lengths must be provided as
+ a secondary input; pointer to the encoding table must be
+ provided
+
+
+ 513
+ Coprocessor services
+
+
+ Code Format Description
+ 0xC Fixed width byte packed with Up to 16 bytes before the encoding; compressed stream
+ run length encoding, followed by bits are read most significant bit to least significant bit
+ Huffman (CCB version 0) or within a byte; data stream of run lengths must be provided
+ OZIP (CCB version 1) encoding as a secondary input; pointer to the encoding table must
+ be provided
+ 0xD Fixed width bit packed with Up to 15 bits (CCB version 0) or 23 bits(CCB version 1)
+ run length encoding, followed by before the encoding; compressed stream bits are read most
+ Huffman (CCB version 0) or significant bit to least significant bit within a byte; data
+ OZIP (CCB version 1) encoding stream of run lengths must be provided as a secondary
+ input; pointer to the encoding table must be provided
+
+ If OZIP encoding is used, there must be no reserved bytes in the table.
+
+36.2.1.1.2. Primary Input Element Size
+
+ For primary input data streams with fixed size elements, the element size must be indicated in the CCB
+ command. The size is encoded as the number of bits or bytes, minus one. The valid value range for this
+ field depends on the input format selected, as listed in the table above.
+
+36.2.1.1.3. Secondary Input Format
+
+ For primary input data streams which require a secondary input stream, the secondary input stream is
+ always encoded in a fixed width, bit-packed format. The bits are read from most significant bit to least
+ significant bit within a byte. There are two encoding options for the secondary input stream data elements,
+ depending on whether the value of 0 is needed:
+
+ Secondary Input Description
+ Format Code
+ 0 Element is stored as value minus 1 (0 evalutes to 1, 1 evalutes
+ to 2, etc)
+ 1 Element is stored as value
+
+36.2.1.1.4. Secondary Input Element Size
+
+ Secondary input element size is encoded as a two bit field:
+
+ Secondary Input Size Description
+ Code
+ 0x0 1 bit
+ 0x1 2 bits
+ 0x2 4 bits
+ 0x3 8 bits
+
+36.2.1.1.5. Input Element Offsets
+
+ Bit-wise input data streams may have any alignment within the base addressed byte. The offset, specified
+ from most significant bit to least significant bit, is provided as a fixed 3 bit field for each input type. A
+ value of 0 indicates that the first input element begins at the most significant bit in the first byte, and a
+ value of 7 indicates it begins with the least significant bit.
+
+ This field should be zero for any byte-wise primary input data streams.
+
+
+ 514
+ Coprocessor services
+
+
+36.2.1.1.6. Output Format
+
+ Query commands support multiple sizes and encodings for output data streams. There are four possible
+ output encodings, and up to four supported element sizes per encoding. Not all output encodings are
+ supported for every command. The format is indicated by a 4-bit field in the CCB:
+
+ Output Format Code Description
+ 0x0 Byte aligned, 1 byte elements
+ 0x1 Byte aligned, 2 byte elements
+ 0x2 Byte aligned, 4 byte elements
+ 0x3 Byte aligned, 8 byte elements
+ 0x4 16 byte aligned, 16 byte elements
+ 0x5 Reserved
+ 0x6 Reserved
+ 0x7 Reserved
+ 0x8 Packed vector of single bit elements
+ 0x9 Reserved
+ 0xA Reserved
+ 0xB Reserved
+ 0xC Reserved
+ 0xD 2 byte elements where each element is the index value of a bit,
+ from an bit vector, which was 1.
+ 0xE 4 byte elements where each element is the index value of a bit,
+ from an bit vector, which was 1.
+ 0xF Reserved
+
+36.2.1.1.7. Application Data Integrity (ADI)
+
+ On platforms which support ADI, the ADI version number may be specified for each separate memory
+ access type used in the CCB command. ADI checking only occurs when reading data. When writing data,
+ the specified ADI version number overwrites any existing ADI value in memory.
+
+ An ADI version value of 0 or 0xF indicates the ADI checking is disabled for that data access, even if it is
+ enabled in memory. By setting the appropriate flag in CCB_SUBMIT (Section 36.3.1, “ccb_submit”) it is
+ also an option to disable ADI checking for all inputs accessed via virtual address for all CCBs submitted
+ during that hypercall invocation.
+
+ The ADI value is only guaranteed to be checked on the first 64 bytes of each data access. Mismatches on
+ subsequent data chunks may not be detected, so guest software should be careful to use page size checking
+ to protect against buffer overruns.
+
+36.2.1.1.8. Page size checking
+
+ All data accesses used in CCB commands must be bounded within a single memory page. When addresses
+ are provided using a virtual address, the page size for checking is extracted from the TTE for that virtual
+ address. When using real addresses, the guest must supply the page size in the same field as the address
+ value. The page size must be one of the sizes supported by the underlying virtual machine. Using a value
+ that is not supported may result in the CCB submission being rejected or the generation of a CCB parsing
+ error in the completion area.
+
+
+ 515
+ Coprocessor services
+
+
+36.2.1.2. Extract command
+
+ Converts an input vector in one format to an output vector in another format. All input format types are
+ supported.
+
+ The only supported output format is a padded, byte-aligned output stream, using output codes 0x0 - 0x4.
+ When the specified output element size is larger than the extracted input element size, zeros are padded to
+ the extracted input element. First, if the decompressed input size is not a whole number of bytes, 0 bits are
+ padded to the most significant bit side till the next byte boundary. Next, if the output element size is larger
+ than the byte padded input element, bytes of value 0 are added based on the Padding Direction bit in the
+ CCB. If the output element size is smaller than the byte-padded input element size, the input element is
+ truncated by dropped from the least significant byte side until the selected output size is reached.
+
+ The return value of the CCB completion area is invalid. The “number of elements processed” field in the
+ CCB completion area will be valid.
+
+ The extract CCB is a 64-byte “short format” CCB.
+
+ The extract CCB command format can be specified by the following packed C structure for a big-endian
+ machine:
+
+
+ struct extract_ccb {
+ uint32_t header;
+ uint32_t control;
+ uint64_t completion;
+ uint64_t primary_input;
+ uint64_t data_access_control;
+ uint64_t secondary_input;

+
+36.2.1.3. Scan commands
+
+ The scan commands search a stream of input data elements for values which match the selection criteria.
+ All the input format types are supported. There are multiple formats for the scan commands, allowing the
+ scan to search for exact matches to one value, exact matches to either of two values, or any value within
+ a specified range. The specific type of scan is indicated by the command code in the CCB header. For the
+ scan range commands, the boundary conditions can be specified as greater-than-or-equal-to a value, less-
+ than-or-equal-to a value, or both by using two boundary values.
+
+ There are two supported formats for the output stream: the bit vector and index array formats (codes 0x8,
+ 0xD, and 0xE). For the standard scan command using the bit vector output, for each input element there
+ exists one bit in the vector that is set if the input element matched the scan criteria, or clear if not. The
+ inverted scan command inverts the polarity of the bits in the output. The most significant bit of the first
+ byte of the output stream corresponds to the first element in the input stream. The standard index array
+ output format contains one array entry for each input element that matched the scan criteria. Each array
+
+
+
+ 519
+ Coprocessor services
+
+
+entry is the index of an input element that matched the scan criteria. An inverted scan command produces
+a similar array, but of all the input elements which did NOT match the scan criteria.
+
+The return value of the CCB completion area contains the number of input elements found which match
+the scan criteria (or number that did not match for the inverted scans). The “number of elements processed”
+field in the CCB completion area will be valid, indicating the number of input elements processed.
+
+These commands are 128-byte “long format” CCBs.
+
+The scan CCB command format can be specified by the following packed C structure for a big-endian
+machine:
+
+
+ struct scan_ccb {
+ uint32_t header;
+ uint32_t control;
+ uint64_t completion;
+ uint64_t primary_input;

+36.2.1.4. Translate commands
+
+ The translate commands takes an input array of indicies, and a table of single bit values indexed by those
+ indicies, and outputs a bit vector or index array created by reading the tables bit value at each index in
+ the input array. The output should therefore contain exactly one bit per index in the input data stream,
+ when outputing as a bit vector. When outputing as an index array, the number of elements depends on the
+ values read in the bit table, but will always be less than, or equal to, the number of input elements. Only
+ a restricted subset of the possible input format types are supported. No variable width or Huffman/OZIP
+ encoded input streams are allowed. The primary input data element size must be 3 bytes or less.
+
+ The maximum table index size allowed is 15 bits, however, larger input elements may be used to provide
+ additional processing of the output values. If 2 or 3 byte values are used, the least significant 15 bits are
+ used as an index into the bit table. The most significant 9 bits (when using 3-byte input elements) or single
+ bit (when using 2-byte input elements) are compared against a fixed 9-bit test value provided in the CCB.
+ If the values match, the value from the bit table is used as the output element value. If the values do not
+ match, the output data element value is forced to 0.
+
+ In the inverted translate operation, the bit value read from bit table is inverted prior to its use. The additional
+ additional processing based on any additional non-index bits remains unchanged, and still forces the output
+ element value to 0 on a mismatch. The specific type of translate command is indicated by the command
+ code in the CCB header.
+
+ There are two supported formats for the output stream: the bit vector and index array formats (codes 0x8,
+ 0xD, and 0xE). The index array format is an array of indicies of bits which would have been set if the
+ output format was a bit array.
+
+ The return value of the CCB completion area contains the number of bits set in the output bit vector,
+ or number of elements in the output index array. The “number of elements processed” field in the CCB
+ completion area will be valid, indicating the number of input elements processed.
+
+ These commands are 64-byte “short format” CCBs.
+
+ The translate CCB command format can be specified by the following packed C structure for a big-endian
+ machine:
+
+
+ struct translate_ccb {

+ The select command filters the primary input data stream by using a secondary input bit vector to determine
+ which input elements to include in the output. For each bit set at a given index N within the bit vector,
+ the Nth input element is included in the output. If the bit is not set, the element is not included. Only a
+ restricted subset of the possible input format types are supported. No variable width or run length encoded
+ input streams are allowed, since the secondary input stream is used for the filtering bit vector.
+
+ The only supported output format is a padded, byte-aligned output stream. The stream follows the same
+ rules and restrictions as padded output stream described in Section 36.2.1.2, “Extract command”.
+
+ The return value of the CCB completion area contains the number of bits set in the input bit vector. The

+36.2.1.6. No-op and Sync commands
+ The no-op (no operation) command is a CCB which has no processing effect. The CCB, when processed
+ by the virtual machine, simply updates the completion area with its execution status. The CCB may have
+ the serial-conditional flags set in order to restrict when it executes.
+
+ The sync command is a variant of the no-op command which with restricted execution timing. A sync
+ command CCB will only execute when all previous commands submitted in the same request have
+ completed. This is stronger than the conditional flag sequencing, which is only dependent on a single
+ previous serial CCB. While the relative ordering is guaranteed, virtual machine implementations with
+ shared hardware resources may cause the sync command to wait for longer than the minimum required
+ time.
+
+ The return value of the CCB completion area is invalid for these CCBs. The “number of elements
+ processed” field is also invalid for these CCBs.
+
+ These commands are 64-byte “short format” CCBs.
+
+ The no-op CCB command format can be specified by the following packed C structure for a big-endian
+ machine:
+
+

+36.2.2. CCB Completion Area
+ All CCB commands use a common 128-byte Completion Area format, which can be specified by the
+ following packed C structure for a big-endian machine:
+
+
+ struct completion_area {
+ uint8_t status_flag;
+ uint8_t error_note;

+ uint8_t rsvd2[20];
+ uint64_t return_value;
+ uint64_t extra_return_value[8];
+ };
+
+
+ The Completion Area must be a 128-byte aligned memory location. The exact layout can be described
+ using byte offsets and sizes relative to the memory base:
+
+ Offset Size Field Description
+ 0 1 CCB execution status
+ 0x0 Command not yet completed

+
+The CCB completion area should be treated as read-only by guest software. The CCB execution status
+byte will be cleared by the Hypervisor to reflect the pending execution status when the CCB is submitted
+successfully. All other fields are considered invalid upon CCB submission until the CCB execution status
+byte becomes non-zero.
+
+CCBs which complete with status 0x2 or 0x3 may produce partial results and/or side effects due to partial
+execution of the CCB command. Some valid data may be accessible depending on the fault type, however,
+it is recommended that guest software treat the destination buffer as being in an unknown state. If a CCB
+completes with a status byte of 0x2, the error reason code byte can be read to determine what corrective
+action should be taken.
+
+A buffer overflow indicates that the results of the operation exceeded the size of the output buffer indicated
+in the CCB. The operation can be retried by resubmitting the CCB with a larger output buffer.
+
+A CCB decoding error indicates that the CCB contained some invalid field values. It may be also be
+triggered if the CCB output is directed at a non-existent secondary input and the pipelining hint is followed.
+
+A page overflow error indicates that the operation required accessing a memory location beyond the page
+size associated with a given address. No data will have been read or written past the page boundary, but
+partial results may have been written to the destination buffer. The CCB can be resubmitted with a larger
+page size memory allocation to complete the operation.
+
+
+ 527
+ Coprocessor services
+
+
+ In the case of pipelined CCBs, a page overflow error will be triggered if the output from the pipeline source
+ CCB ends before the input of the pipeline target CCB. Page boundaries are ignored when the pipeline
+ hint is followed.
+
+ Command kill indicates that the CCB execution was halted or prevented by use of the ccb_kill API call.
+
+ Command timeout indicates that the CCB execution began, but did not complete within a pre-determined
+ limit set by the virtual machine. The command may have produced some or no output. The CCB may be
+ resubmitted with no alterations.
+
+ ADI miscompare indicates that the memory buffer version specified in the CCB did not match the value
+ in memory when accessed by the virtual machine. Guest software should not attempt to resubmit the CCB
+ without determining the cause of the version mismatch.
+
+ A data format error indicates that the input data stream did not follow the specified data input formatting
+ selected in the CCB.
+
+ Some CCBs which encounter hardware errors may be resubmitted without change. Persistent hardware
+ errors may result in multiple failures until RAS software can identify and isolate the faulty component.
+
+ The output size field indicates the number of bytes of valid output in the destination buffer. This field is
+ not valid for all possible CCB commands.
+
+ The runtime field indicates the execution time of the CCB command once it leaves the internal virtual
+ machine queue. The time units are fixed, but unspecified, allowing only relative timing comparisons
+ by guest software. The time units may also vary by hardware platform, and should not be construed to
+ represent any absolute time value.
+
+ Some data query commands process data in units of elements. If applicable to the command, the number of
+ elements processed is indicated in the listed field. This field is not valid for all possible CCB commands.
+
+ The return value and extended return value fields are output locations for commands which do not use
+ a destination output buffer, or have secondary return results. The field is not valid for all possible CCB
+ commands.

+ Submit one or more coprocessor control blocks (CCBs) for evaluation and processing by the virtual

+ Coprocessor services
+
+
+The address should be aligned to the size indicated by length, rounded up to the nearest power of
+two. Virtual machines implementations may reject submissions which do not adhere to that alignment.
+length must be a multiple of 64 bytes. If length is zero, the maximum supported array length will be
+returned as length in ret1. In all other cases, the length value in ret1 will reflect the number of bytes
+successfully consumed from the input CCB array.
+
+ Implementation note
+ Virtual machines should never reject submissions based on the alignment of address if the
+ entire array is contained within a single memory page of the smallest page size supported by the
+ virtual machine.
+
+A guest may choose to submit addresses used in this API function, including the CCB array address,
+as either a real or virtual addresses, with the type of each address indicated in flags. Virtual addresses
+must be present in either the TLB or an active TSB to be processed. The translation context for virtual
+addresses is determined by a combination of CCB contents and the flags argument.
+
+The flags argument is divided into multiple fields defined as follows:
+
+
+Bits Field Description
+[63:16] Reserved
+[15] Disable ADI for VA reads (in API 2.0)
+ Reserved (in API 1.0)
+[14] Virtual addresses within CCBs are translated in privileged context
+[13:12] Alternate translation context for virtual addresses within CCBs:
+ 0b'00 CCBs requesting alternate context are rejected
+ 0b'01 Reserved
+ 0b'10 CCBs requesting alternate context use secondary context
+ 0b'11 CCBs requesting alternate context use nucleus context
+[11:9] Reserved
+[8] Queue info flag
+[7] All-or-nothing flag
+[6] If address is a virtual address, treat its translation context as privileged
+[5:4] Address type of address:

+ 0b'01 Virtual address in primary context
+ 0b'10 Virtual address in secondary context
+ 0b'11 Virtual address in nucleus context
+[3:2] Reserved
+[1:0] CCB command type:
+ 0b'00 Reserved
+ 0b'01 Reserved
+ 0b'10 Query command
+ 0b'11 Reserved
+
+
+
+ 529
+ Coprocessor services
+
+
+ The CCB submission type and address type for the CCB array must be provided in the flags argument.
+ All other fields are optional values which change the default behavior of the CCB processing.
+
+ When set to one, the "Disable ADI for VA reads" bit will turn off ADI checking when using a virtual
+ address to load data. ADI checking will still be done when loading real-addressed memory. This bit is only
+ available when using major version 2 of the coprocessor API group; at major version 1 it is reserved. For
+ more information about using ADI and DAX, see Section 36.2.1.1.7, “Application Data Integrity (ADI)”.
+
+ By default, all virtual addresses are treated as user addresses. If the virtual address translations are
+ privileged, they must be marked as such in the appropriate flags field. The virtual addresses used within
+ the submitted CCBs must all be translated with the same privilege level.
+
+ By default, all virtual addresses used within the submitted CCBs are translated using the primary context
+ active at the time of the submission. The address type field within a CCB allows each address to request
+ translation in an alternate address context. The address context used when the alternate address context is
+ requested is selected in the flags argument.
+
+ The all-or-nothing flag specifies whether the virtual machine should allow partial submissions of the
+ input CCB array. When using CCBs with serial-conditional flags, it is strongly recommended to use
+ the all-or-nothing flag to avoid broken conditional chains. Using long CCB chains on a machine under
+ high coprocessor load may make this impractical, however, and require submitting without the flag.
+ When submitting serial-conditional CCBs without the all-or-nothing flag, guest software must manually
+ implement the serial-conditional behavior at any point where the chain was not submitted in a single API
+ call, and resubmission of the remaining CCBs should clear any conditional flag that might be set in the
+ first remaining CCB. Failure to do so will produce indeterminate CCB execution status and ordering.
+
+ When the all-or-nothing flag is not specified, callers should check the value of length in ret1 to determine
+ how many CCBs from the array were successfully submitted. Any remaining CCBs can be resubmitted
+ without modifications.
+
+ The value of length in ret1 is also valid when the API call returns an error, and callers should always
+ check its value to determine which CCBs in the array were already processed. This will additionally
+ identify which CCB encountered the processing error, and was not submitted successfully.
+
+ If the queue info flag is used during submission, and at least one CCB was successfully submitted, the
+ length value in ret1 will be a multi-field value defined as follows:
+ Bits Field Description
+ [63:48] DAX unit instance identifier
+ [47:32] DAX queue instance identifier
+ [31:16] Reserved
+ [15:0] Number of CCB bytes successfully submitted
+
+ The value of status data depends on the status value. See error status code descriptions for details.
+ The value is undefined for status values that do not specifically list a value for the status data.
+
+ The API has a reserved input and output register which will be used in subsequent minor versions of this
+ API function. Guest software implementations should treat that register as voltile across the function call
+ in order to maintain forward compatibility.
+
+36.3.1.1. Errors
+ EOK One or more CCBs have been accepted and enqueued in the virtual machine
+ and no errors were been encountered during submission. Some submitted
+ CCBs may not have been enqueued due to internal virtual machine limitations,
+ and may be resubmitted without changes.
+
+
+ 530
+ Coprocessor services
+
+
+EWOULDBLOCK An internal resource conflict within the virtual machine has prevented it from
+ being able to complete the CCB submissions sufficiently quickly, requiring
+ it to abandon processing before it was complete. Some CCBs may have been
+ successfully enqueued prior to the block, and all remaining CCBs may be
+ resubmitted without changes.
+EBADALIGN CCB array is not on a 64-byte boundary, or the array length is not a multiple
+ of 64 bytes.
+ENORADDR A real address used either for the CCB array, or within one of the submitted
+ CCBs, is not valid for the guest. Some CCBs may have been enqueued prior
+ to the error being detected.
+ENOMAP A virtual address used either for the CCB array, or within one of the submitted
+ CCBs, could not be translated by the virtual machine using either the TLB
+ or TSB contents. The submission may be retried after adding the required
+ mapping, or by converting the virtual address into a real address. Due to the
+ shared nature of address translation resources, there is no theoretical limit on
+ the number of times the translation may fail, and it is recommended all guests
+ implement some real address based backup. The virtual address which failed
+ translation is returned as status data in ret2. Some CCBs may have been
+ enqueued prior to the error being detected.
+EINVAL The virtual machine detected an invalid CCB during submission, or invalid
+ input arguments, such as bad flag values. Note that not all invalid CCB values
+ will be detected during submission, and some may be reported as errors in the
+ completion area instead. Some CCBs may have been enqueued prior to the
+ error being detected. This error may be returned if the CCB version is invalid.
+ETOOMANY The request was submitted with the all-or-nothing flag set, and the array size is
+ greater than the virtual machine can support in a single request. The maximum
+ supported size for the current virtual machine can be queried by submitting a
+ request with a zero length array, as described above.
+ENOACCESS The guest does not have permission to submit CCBs, or an address used in a
+ CCBs lacks sufficient permissions to perform the required operation (no write
+ permission on the destination buffer address, for example). A virtual address
+ which fails permission checking is returned as status data in ret2. Some
+ CCBs may have been enqueued prior to the error being detected.
+EUNAVAILABLE The requested CCB operation could not be performed at this time. The
+ restricted operation availability may apply only to the first unsuccessfully
+ submitted CCB, or may apply to a larger scope. The status should not be
+ interpreted as permanent, and the guest should attempt to submit CCBs in
+ the future which had previously been unable to be performed. The status
+ data provides additional information about scope of the retricted availability
+ as follows:
+ Value Description
+ 0 Processing for the exact CCB instance submitted was unavailable,
+ and it is recommended the guest emulate the operation. The
+ guest should continue to submit all other CCBs, and assume no
+ restrictions beyond this exact CCB instance.
+ 1 Processing is unavailable for all CCBs using the requested opcode,
+ and it is recommended the guest emulate the operation. The
+ guest should continue to submit all other CCBs that use different
+ opcodes, but can expect continued rejections of CCBs using the
+ same opcode in the near future.

+ different CCB versions, but can expect continued rejections of
+ CCBs using the same CCB version in the near future.
+ 3 Processing is unavailable for all CCBs on the submitting vcpu,
+ and it is recommended the guest emulate the operation or resubmit
+ the CCB on a different vcpu. The guest should continue to submit
+ CCBs on all other vcpus but can expect continued rejections of all
+ CCBs on this vcpu in the near future.
+ 4 Processing is unavailable for all CCBs, and it is recommended

+Oracle Data Analytics Accelerator (DAX)
+---------------------------------------
+
+DAX is a coprocessor which resides on the SPARC M7 (DAX1) and M8
+(DAX2) processor chips, and has direct access to the CPU's L3 caches
+as well as physical memory. It can perform several operations on data
+streams with various input and output formats. A driver provides a
+transport mechanism and has limited knowledge of the various opcodes
+and data formats. A user space library provides high level services
+and translates these into low level commands which are then passed
+into the driver and subsequently the Hypervisor and the coprocessor.
+The library is the recommended way for applications to use the
+coprocessor, and the driver interface is not intended for general use.
+This document describes the general flow of the driver, its
+structures, and its programmatic interface. It also provides example
+code sufficient to write user or kernel applications that use DAX
+functionality.
+
+The user library is open source and available at:
+ https://oss.oracle.com/git/gitweb.cgi?p=libdax.git
+
+The Hypervisor interface to the coprocessor is described in detail in
+the accompanying document, dax-hv-api.txt, which is a plain text
+excerpt of the (Oracle internal) "UltraSPARC Virtual Machine
+Specification" version 3.0.20+15, dated 2017-09-25.
+
+
+High Level Overview
+-------------------
+
+A coprocessor request is described by a Command Control Block
+(CCB). The CCB contains an opcode and various parameters. The opcode
+specifies what operation is to be done, and the parameters specify
+options, flags, sizes, and addresses. The CCB (or an array of CCBs)
+is passed to the Hypervisor, which handles queueing and scheduling of
+requests to the available coprocessor execution units. A status code
+returned indicates if the request was submitted successfully or if
+there was an error. One of the addresses given in each CCB is a
+pointer to a "completion area", which is a 128 byte memory block that
+is written by the coprocessor to provide execution status. No
+interrupt is generated upon completion; the completion area must be
+polled by software to find out when a transaction has finished, but
+the M7 and later processors provide a mechanism to pause the virtual
+processor until the completion status has been updated by the
+coprocessor. This is done using the monitored load and mwait
+instructions, which are described in more detail later. The DAX
+coprocessor was designed so that after a request is submitted, the
+kernel is no longer involved in the processing of it. The polling is
+done at the user level, which results in almost zero latency between
+completion of a request and resumption of execution of the requesting
+thread.
+
+
+Addressing Memory
+-----------------
+
+The kernel does not have access to physical memory in the Sun4v
+architecture, as there is an additional level of memory virtualization
+present. This intermediate level is called "real" memory, and the
+kernel treats this as if it were physical. The Hypervisor handles the
+translations between real memory and physical so that each logical
+domain (LDOM) can have a partition of physical memory that is isolated
+from that of other LDOMs. When the kernel sets up a virtual mapping,
+it specifies a virtual address and the real address to which it should
+be mapped.
+
+The DAX coprocessor can only operate on physical memory, so before a
+request can be fed to the coprocessor, all the addresses in a CCB must
+be converted into physical addresses. The kernel cannot do this since
+it has no visibility into physical addresses. So a CCB may contain
+either the virtual or real addresses of the buffers or a combination
+of them. An "address type" field is available for each address that
+may be given in the CCB. In all cases, the Hypervisor will translate
+all the addresses to physical before dispatching to hardware. Address
+translations are performed using the context of the process initiating
+the request.
+
+
+The Driver API
+--------------
+
+An application makes requests to the driver via the write() system
+call, and gets results (if any) via read(). The completion areas are
+made accessible via mmap(), and are read-only for the application.
+
+The request may either be an immediate command or an array of CCBs to
+be submitted to the hardware.
+
+Each open instance of the device is exclusive to the thread that
+opened it, and must be used by that thread for all subsequent
+operations. The driver open function creates a new context for the
+thread and initializes it for use. This context contains pointers and
+values used internally by the driver to keep track of submitted
+requests. The completion area buffer is also allocated, and this is
+large enough to contain the completion areas for many concurrent
+requests. When the device is closed, any outstanding transactions are
+flushed and the context is cleaned up.
+
+On a DAX1 system (M7), the device will be called "oradax1", while on a
+DAX2 system (M8) it will be "oradax2". If an application requires one
+or the other, it should simply attempt to open the appropriate
+device. Only one of the devices will exist on any given system, so the
+name can be used to determine what the platform supports.
+
+The immediate commands are CCB_DEQUEUE, CCB_KILL, and CCB_INFO. For
+all of these, success is indicated by a return value from write()
+equal to the number of bytes given in the call. Otherwise -1 is
+returned and errno is set.
+
+CCB_DEQUEUE
+
+Tells the driver to clean up resources associated with past
+requests. Since no interrupt is generated upon the completion of a
+request, the driver must be told when it may reclaim resources. No
+further status information is returned, so the user should not
+subsequently call read().
+
+CCB_KILL
+
+Kills a CCB during execution. The CCB is guaranteed to not continue
+executing once this call returns successfully. On success, read() must
+be called to retrieve the result of the action.
+
+CCB_INFO
+
+Retrieves information about a currently executing CCB. Note that some
+Hypervisors might return 'notfound' when the CCB is in 'inprogress'
+state. To ensure a CCB in the 'notfound' state will never be executed,
+CCB_KILL must be invoked on that CCB. Upon success, read() must be
+called to retrieve the details of the action.
+
+Submission of an array of CCBs for execution
+
+A write() whose length is a multiple of the CCB size is treated as a
+submit operation. The file offset is treated as the index of the
+completion area to use, and may be set via lseek() or using the
+pwrite() system call. If -1 is returned then errno is set to indicate
+the error. Otherwise, the return value is the length of the array that
+was actually accepted by the coprocessor. If the accepted length is
+equal to the requested length, then the submission was completely
+successful and there is no further status needed; hence, the user
+should not subsequently call read(). Partial acceptance of the CCB
+array is indicated by a return value less than the requested length,
+and read() must be called to retrieve further status information. The
+status will reflect the error caused by the first CCB that was not
+accepted, and status_data will provide additional data in some cases.
+
+MMAP
+
+The mmap() function provides access to the completion area allocated
+in the driver. Note that the completion area is not writeable by the
+user process, and the mmap call must not specify PROT_WRITE.
+
+
+Completion of a Request
+-----------------------
+
+The first byte in each completion area is the command status which is
+updated by the coprocessor hardware. Software may take advantage of
+new M7/M8 processor capabilities to efficiently poll this status byte.
+First, a "monitored load" is achieved via a Load from Alternate Space
+(ldxa, lduba, etc.) with ASI 0x84 (ASI_MONITOR_PRIMARY). Second, a
+"monitored wait" is achieved via the mwait instruction (a write to
+%asr28). This instruction is like pause in that it suspends execution
+of the virtual processor for the given number of nanoseconds, but in
+addition will terminate early when one of several events occur. If the
+block of data containing the monitored location is modified, then the
+mwait terminates. This causes software to resume execution immediately
+(without a context switch or kernel to user transition) after a
+transaction completes. Thus the latency between transaction completion
+and resumption of execution may be just a few nanoseconds.
+
+
+Application Life Cycle of a DAX Submission
+------------------------------------------
+
+ - open dax device
+ - call mmap() to get the completion area address
+ - allocate a CCB and fill in the opcode, flags, parameters, addresses, etc.
+ - submit CCB via write() or pwrite()
+ - go into a loop executing monitored load + monitored wait and
+ terminate when the command status indicates the request is complete
+ (CCB_KILL or CCB_INFO may be used any time as necessary)
+ - perform a CCB_DEQUEUE
+ - call munmap() for completion area
+ - close the dax device
+
+
+Memory Constraints
+------------------
+
+The DAX hardware operates only on physical addresses. Therefore, it is
+not aware of virtual memory mappings and the discontiguities that may
+exist in the physical memory that a virtual buffer maps to. There is
+no I/O TLB or any scatter/gather mechanism. All buffers, whether input
+or output, must reside in a physically contiguous region of memory.
+
+The Hypervisor translates all addresses within a CCB to physical
+before handing off the CCB to DAX. The Hypervisor determines the
+virtual page size for each virtual address given, and uses this to
+program a size limit for each address. This prevents the coprocessor
+from reading or writing beyond the bound of the virtual page, even
+though it is accessing physical memory directly. A simpler way of
+saying this is that a DAX operation will never "cross" a virtual page
+boundary. If an 8k virtual page is used, then the data is strictly
+limited to 8k. If a user's buffer is larger than 8k, then a larger
+page size must be used, or the transaction size will be truncated to
+8k.
+
+Huge pages. A user may allocate huge pages using standard interfaces.
+Memory buffers residing on huge pages may be used to achieve much
+larger DAX transaction sizes, but the rules must still be followed,
+and no transaction will cross a page boundary, even a huge page. A
+major caveat is that Linux on Sparc presents 8Mb as one of the huge
+page sizes. Sparc does not actually provide a 8Mb hardware page size,
+and this size is synthesized by pasting together two 4Mb pages. The
+reasons for this are historical, and it creates an issue because only
+half of this 8Mb page can actually be used for any given buffer in a
+DAX request, and it must be either the first half or the second half;
+it cannot be a 4Mb chunk in the middle, since that crosses a
+(hardware) page boundary. Note that this entire issue may be hidden by
+higher level libraries.
+
+
+CCB Structure
+-------------
+A CCB is an array of 8 64-bit words. Several of these words provide
+command opcodes, parameters, flags, etc., and the rest are addresses
+for the completion area, output buffer, and various inputs:
+
+ struct ccb {
+ u64 control;
+ u64 completion;
+ u64 input0;
+ u64 access;
+ u64 input1;
+ u64 op_data;
+ u64 output;
+ u64 table;
+ };
+
+See libdax/common/sys/dax1/dax1_ccb.h for a detailed description of
+each of these fields, and see dax-hv-api.txt for a complete description
+of the Hypervisor API available to the guest OS (ie, Linux kernel).
+
+The first word (control) is examined by the driver for the following:
+ - CCB version, which must be consistent with hardware version
+ - Opcode, which must be one of the documented allowable commands
+ - Address types, which must be set to "virtual" for all the addresses
+ given by the user, thereby ensuring that the application can
+ only access memory that it owns
+
+
+Example Code
+------------
+
+The DAX is accessible to both user and kernel code. The kernel code
+can make hypercalls directly while the user code must use wrappers
+provided by the driver. The setup of the CCB is nearly identical for
+both; the only difference is in preparation of the completion area. An
+example of user code is given now, with kernel code afterwards.
+
+In order to program using the driver API, the file
+arch/sparc/include/uapi/asm/oradax.h must be included.
+
+First, the proper device must be opened. For M7 it will be
+/dev/oradax1 and for M8 it will be /dev/oradax2. The simplest
+procedure is to attempt to open both, as only one will succeed:
+
+ fd = open("/dev/oradax1", O_RDWR);
+ if (fd < 0)
+ fd = open("/dev/oradax2", O_RDWR);
+ if (fd < 0)
+ /* No DAX found */
+
+Next, the completion area must be mapped:
+
+ completion_area = mmap(NULL, DAX_MMAP_LEN, PROT_READ, MAP_SHARED, fd, 0);
+
+All input and output buffers must be fully contained in one hardware
+page, since as explained above, the DAX is strictly constrained by
+virtual page boundaries. In addition, the output buffer must be
+64-byte aligned and its size must be a multiple of 64 bytes because
+the coprocessor writes in units of cache lines.
+
+This example demonstrates the DAX Scan command, which takes as input a
+vector and a match value, and produces a bitmap as the output. For
+each input element that matches the value, the corresponding bit is
+set in the output.
+
+In this example, the input vector consists of a series of single bits,
+and the match value is 0. So each 0 bit in the input will produce a 1
+in the output, and vice versa, which produces an output bitmap which
+is the input bitmap inverted.
+
+For details of all the parameters and bits used in this CCB, please
+refer to section 36.2.1.3 of the DAX Hypervisor API document, which
+describes the Scan command in detail.
+
+ ccb->control = /* Table 36.1, CCB Header Format */
+ (2L << 48) /* command = Scan Value */
+ | (3L << 40) /* output address type = primary virtual */
+ | (3L << 34) /* primary input address type = primary virtual */
+ /* Section 36.2.1, Query CCB Command Formats */
+ | (1 << 28) /* 36.2.1.1.1 primary input format = fixed width bit packed */
+ | (0 << 23) /* 36.2.1.1.2 primary input element size = 0 (1 bit) */
+ | (8 << 10) /* 36.2.1.1.6 output format = bit vector */
+ | (0 << 5) /* 36.2.1.3 First scan criteria size = 0 (1 byte) */
+ | (31 << 0); /* 36.2.1.3 Disable second scan criteria */
+
+ ccb->completion = 0; /* Completion area address, to be filled in by driver */
+
+ ccb->input0 = (unsigned long) input; /* primary input address */
+
+ ccb->access = /* Section 36.2.1.2, Data Access Control */
+ (2 << 24) /* Primary input length format = bits */
+ | (nbits - 1); /* number of bits in primary input stream, minus 1 */
+
+ ccb->input1 = 0; /* secondary input address, unused */
+
+ ccb->op_data = 0; /* scan criteria (value to be matched) */
+
+ ccb->output = (unsigned long) output; /* output address */
+
+ ccb->table = 0; /* table address, unused */
+
+The CCB submission is a write() or pwrite() system call to the
+driver. If the call fails, then a read() must be used to retrieve the
+status:
+
+ if (pwrite(fd, ccb, 64, 0) != 64) {
+ struct ccb_exec_result status;
+ read(fd, &status, sizeof(status));
+ /* bail out */
+ }
+
+After a successful submission of the CCB, the completion area may be
+polled to determine when the DAX is finished. Detailed information on
+the contents of the completion area can be found in section 36.2.2 of
+the DAX HV API document.
+
+ while (1) {
+ /* Monitored Load */
+ __asm__ __volatile__("lduba [%1] 0x84, %0\n"
+ : "=r" (status)
+ : "r" (completion_area));
+
+ if (status) /* 0 indicates command in progress */
+ break;
+
+ /* MWAIT */
+ __asm__ __volatile__("wr %%g0, 1000, %%asr28\n" ::); /* 1000 ns */
+ }
+
+A completion area status of 1 indicates successful completion of the
+CCB and validity of the output bitmap, which may be used immediately.
+All other non-zero values indicate error conditions which are
+described in section 36.2.2.
+
+ if (completion_area[0] != 1) { /* section 36.2.2, 1 = command ran and succeeded */
+ /* completion_area[0] contains the completion status */
+ /* completion_area[1] contains an error code, see 36.2.2 */
+ }
+
+After the completion area has been processed, the driver must be
+notified that it can release any resources associated with the
+request. This is done via the dequeue operation:
+
+ struct dax_command cmd;
+ cmd.command = CCB_DEQUEUE;
+ if (write(fd, &cmd, sizeof(cmd)) != sizeof(cmd)) {
+ /* bail out */
+ }
+
+Finally, normal program cleanup should be done, i.e., unmapping
+completion area, closing the dax device, freeing memory etc.
+
+[Kernel example]
+
+The only difference in using the DAX in kernel code is the treatment
+of the completion area. Unlike user applications which mmap the
+completion area allocated by the driver, kernel code must allocate its
+own memory to use for the completion area, and this address and its
+type must be given in the CCB:
+
+ ccb->control |= /* Table 36.1, CCB Header Format */
+ (3L << 32); /* completion area address type = primary virtual */
+
+ ccb->completion = (unsigned long) completion_area; /* Completion area address */
+
+The dax submit hypercall is made directly. The flags used in the
+ccb_submit call are documented in the DAX HV API in section 36.3.1.
+
+#include <asm/hypervisor.h>
+
+ hv_rv = sun4v_ccb_submit((unsigned long)ccb, 64,
+ HV_CCB_QUERY_CMD |
+ HV_CCB_ARG0_PRIVILEGED | HV_CCB_ARG0_TYPE_PRIMARY |
+ HV_CCB_VA_PRIVILEGED,
+ 0, &bytes_accepted, &status_data);
+
+ if (hv_rv != HV_EOK) {
+ /* hv_rv is an error code, status_data contains */
+ /* potential additional status, see 36.3.1.1 */
+ }
+
+After the submission, the completion area polling code is identical to
+that in user land:
+
+ while (1) {
+ /* Monitored Load */
+ __asm__ __volatile__("lduba [%1] 0x84, %0\n"
+ : "=r" (status)
+ : "r" (completion_area));
+
+ if (status) /* 0 indicates command in progress */
+ break;
+
+ /* MWAIT */
+ __asm__ __volatile__("wr %%g0, 1000, %%asr28\n" ::); /* 1000 ns */
+ }
+
+ if (completion_area[0] != 1) { /* section 36.2.2, 1 = command ran and succeeded */
+ /* completion_area[0] contains the completion status */
+ /* completion_area[1] contains an error code, see 36.2.2 */
+ }
+
+The output bitmap is ready for consumption immediately after the
+completion status indicates success.

+This document explains potential effects of speculation, and how undesirable
+effects can be mitigated portably using common APIs.
+
+===========
+Speculation
+===========
+
+To improve performance and minimize average latencies, many contemporary CPUs
+employ speculative execution techniques such as branch prediction, performing
+work which may be discarded at a later stage.
+
+Typically speculative execution cannot be observed from architectural state,
+such as the contents of registers. However, in some cases it is possible to
+observe its impact on microarchitectural state, such as the presence or
+absence of data in caches. Such state may form side-channels which can be
+observed to extract secret information.
+
+For example, in the presence of branch prediction, it is possible for bounds
+checks to be ignored by code which is speculatively executed. Consider the
+following code:
+
+ int load_array(int *array, unsigned int index)
+ {
+ if (index >= MAX_ARRAY_ELEMS)
+ return 0;
+ else
+ return array[index];
+ }
+
+Which, on arm64, may be compiled to an assembly sequence such as:
+
+ CMP <index>, #MAX_ARRAY_ELEMS
+ B.LT less
+ MOV <returnval>, #0
+ RET
+ less:
+ LDR <returnval>, [<array>, <index>]
+ RET
+
+It is possible that a CPU mis-predicts the conditional branch, and
+speculatively loads array[index], even if index >= MAX_ARRAY_ELEMS. This
+value will subsequently be discarded, but the speculated load may affect
+microarchitectural state which can be subsequently measured.
+
+More complex sequences involving multiple dependent memory accesses may
+result in sensitive information being leaked. Consider the following
+code, building on the prior example:
+
+ int load_dependent_arrays(int *arr1, int *arr2, int index)
+ {
+ int val1, val2,
+
+ val1 = load_array(arr1, index);
+ val2 = load_array(arr2, val1);
+
+ return val2;
+ }
+
+Under speculation, the first call to load_array() may return the value
+of an out-of-bounds address, while the second call will influence
+microarchitectural state dependent on this value. This may provide an
+arbitrary read primitive.
+
+====================================
+Mitigating speculation side-channels
+====================================
+
+The kernel provides a generic API to ensure that bounds checks are
+respected even under speculation. Architectures which are affected by
+speculation-based side-channels are expected to implement these
+primitives.
+
+The array_index_nospec() helper in <linux/nospec.h> can be used to
+prevent information from being leaked via side-channels.
+
+A call to array_index_nospec(index, size) returns a sanitized index
+value that is bounded to [0, size) even under cpu speculation
+conditions.
+
+This can be used to protect the earlier load_array() example:
+
+ int load_array(int *array, unsigned int index)
+ {
+ if (index >= MAX_ARRAY_ELEMS)
+ return 0;
+ else {
+ index = array_index_nospec(index, MAX_ARRAY_ELEMS);
+ return array[index];
+ }
+ }

-2.2 Static power
-
-Static leakage power consumption depends on a number of factors. For a
-given circuit implementation the primary factors are:
-
-- Time the circuit spends in each 'power state'
-- Temperature
-- Operating voltage
-- Process grade
-
-The time the circuit spends in each 'power state' for a given
-evaluation period at first order means OFF or ON. However,
-'retention' states can also be supported that reduce power during
-inactive periods without loss of context.
-
-Note: The visibility of state entries to the OS can vary, according to
-platform specifics, and this can then impact the accuracy of a model
-based on OS state information alone. It might be possible in some
-cases to extract more accurate information from system resources.
-
-The temperature, operating voltage and process 'grade' (slow to fast)
-of the circuit are all significant factors in static leakage power
-consumption. All of these have complex relationships to static power.
-
-Circuit implementation specific factors include the chosen silicon
-process as well as the type, number and size of transistors in both
-the logic gates and any RAM elements included.
-
-The static power consumption modelling must take into account the
-power managed regions that are implemented. Taking the example of an
-ARM processor cluster, the modelling would take into account whether
-each CPU can be powered OFF separately or if only a single power
-region is implemented for the complete cluster.
-
-In one view, there are others, a static power consumption model can
-then start from a set of reference values for each power managed
-region (e.g. CPU, Cluster/L2) in each state (e.g. ON, OFF) at an
-arbitrary process grade, voltage and temperature point. These values
-are then scaled for all of the following: the time in each state, the
-process grade, the current temperature and the operating voltage.
-However, since both implementation specific and complex relationships
-dominate the estimate, the appropriate interface to the model from the
-cpu cooling device is to provide a function callback that calculates
-the static power in this platform. When registering the cpu cooling
-device pass a function pointer that follows the `get_static_t`
-prototype:
-
- int plat_get_static(cpumask_t *cpumask, int interval,
- unsigned long voltage, u32 &power);
-
-`cpumask` is the cpumask of the cpus involved in the calculation.
-`voltage` is the voltage at which they are operating. The function
-should calculate the average static power for the last `interval`
-milliseconds. It returns 0 on success, -E* on error. If it
-succeeds, it should store the static power in `power`. Reading the
-temperature of the cpus described by `cpumask` is left for
-plat_get_static() to do as the platform knows best which thermal
-sensor is closest to the cpu.
-
-If `plat_static_func` is NULL, static power is considered to be
-negligible for this platform and only dynamic power is considered.
-
-The platform specific callback can then use any combination of tables
-and/or equations to permute the estimated value. Process grade
-information is not passed to the model since access to such data, from
-on-chip measurement capability or manufacture time data, is platform
-specific.
-
-Note: the significance of static power for CPUs in comparison to
-dynamic power is highly dependent on implementation. Given the
-potential complexity in implementation, the importance and accuracy of
-its inclusion when using cpu cooling devices should be assessed on a
-case by case basis.

+Overview
+========
+
+Page Table Isolation (pti, previously known as KAISER[1]) is a
+countermeasure against attacks on the shared user/kernel address
+space such as the "Meltdown" approach[2].
+
+To mitigate this class of attacks, we create an independent set of
+page tables for use only when running userspace applications. When
+the kernel is entered via syscalls, interrupts or exceptions, the
+page tables are switched to the full "kernel" copy. When the system
+switches back to user mode, the user copy is used again.
+
+The userspace page tables contain only a minimal amount of kernel
+data: only what is needed to enter/exit the kernel such as the
+entry/exit functions themselves and the interrupt descriptor table
+(IDT). There are a few strictly unnecessary things that get mapped
+such as the first C function when entering an interrupt (see
+comments in pti.c).
+
+This approach helps to ensure that side-channel attacks leveraging
+the paging structures do not function when PTI is enabled. It can be
+enabled by setting CONFIG_PAGE_TABLE_ISOLATION=y at compile time.
+Once enabled at compile-time, it can be disabled at boot with the
+'nopti' or 'pti=' kernel parameters (see kernel-parameters.txt).
+
+Page Table Management
+=====================
+
+When PTI is enabled, the kernel manages two sets of page tables.
+The first set is very similar to the single set which is present in
+kernels without PTI. This includes a complete mapping of userspace
+that the kernel can use for things like copy_to_user().
+
+Although _complete_, the user portion of the kernel page tables is
+crippled by setting the NX bit in the top level. This ensures
+that any missed kernel->user CR3 switch will immediately crash
+userspace upon executing its first instruction.
+
+The userspace page tables map only the kernel data needed to enter
+and exit the kernel. This data is entirely contained in the 'struct
+cpu_entry_area' structure which is placed in the fixmap which gives
+each CPU's copy of the area a compile-time-fixed virtual address.
+
+For new userspace mappings, the kernel makes the entries in its
+page tables like normal. The only difference is when the kernel
+makes entries in the top (PGD) level. In addition to setting the
+entry in the main kernel PGD, a copy of the entry is made in the
+userspace page tables' PGD.
+
+This sharing at the PGD level also inherently shares all the lower
+layers of the page tables. This leaves a single, shared set of
+userspace page tables to manage. One PTE to lock, one set of
+accessed bits, dirty bits, etc...
+
+Overhead
+========
+
+Protection against side-channel attacks is important. But,
+this protection comes at a cost:
+
+1. Increased Memory Use
+ a. Each process now needs an order-1 PGD instead of order-0.
+ (Consumes an additional 4k per process).
+ b. The 'cpu_entry_area' structure must be 2MB in size and 2MB
+ aligned so that it can be mapped by setting a single PMD
+ entry. This consumes nearly 2MB of RAM once the kernel
+ is decompressed, but no space in the kernel image itself.
+
+2. Runtime Cost
+ a. CR3 manipulation to switch between the page table copies
+ must be done at interrupt, syscall, and exception entry
+ and exit (it can be skipped when the kernel is interrupted,
+ though.) Moves to CR3 are on the order of a hundred
+ cycles, and are required at every entry and exit.
+ b. A "trampoline" must be used for SYSCALL entry. This
+ trampoline depends on a smaller set of resources than the
+ non-PTI SYSCALL entry code, so requires mapping fewer
+ things into the userspace page tables. The downside is
+ that stacks must be switched at entry time.
+ c. Global pages are disabled for all kernel structures not
+ mapped into both kernel and userspace page tables. This
+ feature of the MMU allows different processes to share TLB
+ entries mapping the kernel. Losing the feature means more
+ TLB misses after a context switch. The actual loss of
+ performance is very small, however, never exceeding 1%.
+ d. Process Context IDentifiers (PCID) is a CPU feature that
+ allows us to skip flushing the entire TLB when switching page
+ tables by setting a special bit in CR3 when the page tables
+ are changed. This makes switching the page tables (at context
+ switch, or kernel entry/exit) cheaper. But, on systems with
+ PCID support, the context switch code must flush both the user
+ and kernel entries out of the TLB. The user PCID TLB flush is
+ deferred until the exit to userspace, minimizing the cost.
+ See intel.com/sdm for the gory PCID/INVPCID details.
+ e. The userspace page tables must be populated for each new
+ process. Even without PTI, the shared kernel mappings
+ are created by copying top-level (PGD) entries into each
+ new process. But, with PTI, there are now *two* kernel
+ mappings: one in the kernel page tables that maps everything
+ and one for the entry/exit structures. At fork(), we need to
+ copy both.
+ f. In addition to the fork()-time copying, there must also
+ be an update to the userspace PGD any time a set_pgd() is done
+ on a PGD used to map userspace. This ensures that the kernel
+ and userspace copies always map the same userspace
+ memory.
+ g. On systems without PCID support, each CR3 write flushes
+ the entire TLB. That means that each syscall, interrupt
+ or exception flushes the TLB.
+ h. INVPCID is a TLB-flushing instruction which allows flushing
+ of TLB entries for non-current PCIDs. Some systems support
+ PCIDs, but do not support INVPCID. On these systems, addresses
+ can only be flushed from the TLB for the current PCID. When
+ flushing a kernel address, we need to flush all PCIDs, so a
+ single kernel address flush will require a TLB-flushing CR3
+ write upon the next use of every PCID.
+
+Possible Future Work
+====================
+1. We can be more careful about not actually writing to CR3
+ unless its value is actually changed.
+2. Allow PTI to be enabled/disabled at runtime in addition to the
+ boot-time switching.
+
+Testing
+========
+
+To test stability of PTI, the following test procedure is recommended,
+ideally doing all of these in parallel:
+
+1. Set CONFIG_DEBUG_ENTRY=y
+2. Run several copies of all of the tools/testing/selftests/x86/ tests
+ (excluding MPX and protection_keys) in a loop on multiple CPUs for
+ several minutes. These tests frequently uncover corner cases in the
+ kernel entry code. In general, old kernels might cause these tests
+ themselves to crash, but they should never crash the kernel.
+3. Run the 'perf' tool in a mode (top or record) that generates many
+ frequent performance monitoring non-maskable interrupts (see "NMI"
+ in /proc/interrupts). This exercises the NMI entry/exit code which
+ is known to trigger bugs in code paths that did not expect to be
+ interrupted, including nested NMIs. Using "-c" boosts the rate of
+ NMIs, and using two -c with separate counters encourages nested NMIs
+ and less deterministic behavior.
+
+ while true; do perf record -c 10000 -e instructions,cycles -a sleep 10; done
+
+4. Launch a KVM virtual machine.
+5. Run 32-bit binaries on systems supporting the SYSCALL instruction.
+ This has been a lightly-tested code path and needs extra scrutiny.
+
+Debugging
+=========
+
+Bugs in PTI cause a few different signatures of crashes
+that are worth noting here.
+
+ * Failures of the selftests/x86 code. Usually a bug in one of the
+ more obscure corners of entry_64.S
+ * Crashes in early boot, especially around CPU bringup. Bugs
+ in the trampoline code or mappings cause these.
+ * Crashes at the first interrupt. Caused by bugs in entry_64.S,
+ like screwing up a page table switch. Also caused by
+ incorrectly mapping the IRQ handler entry code.
+ * Crashes at the first NMI. The NMI code is separate from main
+ interrupt handlers and can have bugs that do not affect
+ normal interrupts. Also caused by incorrectly mapping NMI
+ code. NMIs that interrupt the entry code must be very
+ careful and can be the cause of crashes that show up when
+ running perf.
+ * Kernel crashes at the first exit to userspace. entry_64.S
+ bugs, or failing to map some of the exit code.
+ * Crashes at first interrupt that interrupts userspace. The paths
+ in entry_64.S that return to userspace are sometimes separate
+ from the ones that return to the kernel.
+ * Double faults: overflowing the kernel stack because of page
+ faults upon page faults. Caused by touching non-pti-mapped
+ data in the entry code, or forgetting to switch to kernel
+ CR3 before calling into C functions which are not pti-mapped.
+ * Userspace segfaults early in boot, sometimes manifesting
+ as mount(8) failing to mount the rootfs. These have
+ tended to be TLB invalidation issues. Usually invalidating
+ the wrong PCID, or otherwise missing an invalidation.

+
+ Preamble
+
+ The license agreements of most software companies try to keep users
+at the mercy of those companies. By contrast, our General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. The
+General Public License applies to the Free Software Foundation's
+software and to any other program whose authors commit to using it.
+You can use it for your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Specifically, the General Public License is designed to make
+sure that you have the freedom to give away or sell copies of free
+software, that you receive source code or can get it if you want it,
+that you can change the software or use pieces of it in new free
+programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of a such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must tell them their rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any program or other work which
+contains a notice placed by the copyright holder saying it may be
+distributed under the terms of this General Public License. The
+"Program", below, refers to any such program or work, and a "work based
+on the Program" means either the Program or any work containing the
+Program or a portion of it, either verbatim or with modifications. Each
+licensee is addressed as "you".
+
+ 1. You may copy and distribute verbatim copies of the Program's source
+code as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this
+General Public License and to the absence of any warranty; and give any
+other recipients of the Program a copy of this General Public License
+along with the Program. You may charge a fee for the physical act of
+transferring a copy.
+
+ 2. You may modify your copy or copies of the Program or any portion of
+it, and copy and distribute such modifications under the terms of Paragraph
+1 above, provided that you also do the following:
+
+ a) cause the modified files to carry prominent notices stating that
+ you changed the files and the date of any change; and
+
+ b) cause the whole of any work that you distribute or publish, that
+ in whole or in part contains the Program or any part thereof, either
+ with or without modifications, to be licensed at no charge to all
+ third parties under the terms of this General Public License (except
+ that you may choose to grant warranty protection to some or all
+ third parties, at your option).
+
+ c) If the modified program normally reads commands interactively when
+ run, you must cause it, when started running for such interactive use
+ in the simplest and most usual way, to print or display an
+ announcement including an appropriate copyright notice and a notice
+ that there is no warranty (or else, saying that you provide a
+ warranty) and that users may redistribute the program under these
+ conditions, and telling the user how to view a copy of this General
+ Public License.
+
+ d) You may charge a fee for the physical act of transferring a
+ copy, and you may at your option offer warranty protection in
+ exchange for a fee.
+
+Mere aggregation of another independent work with the Program (or its
+derivative) on a volume of a storage or distribution medium does not bring
+the other work under the scope of these terms.
+
+ 3. You may copy and distribute the Program (or a portion or derivative of
+it, under Paragraph 2) in object code or executable form under the terms of
+Paragraphs 1 and 2 above provided that you also do one of the following:
+
+ a) accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of
+ Paragraphs 1 and 2 above; or,
+
+ b) accompany it with a written offer, valid for at least three
+ years, to give any third party free (except for a nominal charge
+ for the cost of distribution) a complete machine-readable copy of the
+ corresponding source code, to be distributed under the terms of
+ Paragraphs 1 and 2 above; or,
+
+ c) accompany it with the information you received as to where the
+ corresponding source code may be obtained. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form alone.)
+
+Source code for a work means the preferred form of the work for making
+modifications to it. For an executable file, complete source code means
+all the source code for all modules it contains; but, as a special
+exception, it need not include source code for modules which are standard
+libraries that accompany the operating system on which the executable
+file runs, or for standard header files or definitions files that
+accompany that operating system.
+
+ 4. You may not copy, modify, sublicense, distribute or transfer the
+Program except as expressly provided under this General Public License.
+Any attempt otherwise to copy, modify, sublicense, distribute or transfer
+the Program is void, and will automatically terminate your rights to use
+the Program under this License. However, parties who have received
+copies, or rights to use copies, from you under this General Public
+License will not have their licenses terminated so long as such parties
+remain in full compliance.
+
+ 5. By copying, distributing or modifying the Program (or any work based
+on the Program) you indicate your acceptance of this license to do so,
+and all its terms and conditions.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the original
+licensor to copy, distribute or modify the Program subject to these
+terms and conditions. You may not impose any further restrictions on the
+recipients' exercise of the rights granted herein.
+
+ 7. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of the license which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+the license, you may choose any version ever published by the Free Software
+Foundation.
+
+ 8. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to humanity, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+ To do so, attach the following notices to the program. It is safest to
+attach them to the start of each source file to most effectively convey
+the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 1, or (at your option)
+ any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19xx name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the
+appropriate parts of the General Public License. Of course, the
+commands you use may be called something other than `show w' and `show
+c'; they could even be mouse-clicks or menu items--whatever suits your
+program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ program `Gnomovision' (a program to direct compilers to make passes
+ at assemblers) written by James Hacker.

+
+3. Distribution Obligations.
+
+ 3.1. Application of License.
+ The Modifications which You create or to which You contribute are
+ governed by the terms of this License, including without limitation
+ Section 2.2. The Source Code version of Covered Code may be
+ distributed only under the terms of this License or a future version
+ of this License released under Section 6.1, and You must include a
+ copy of this License with every copy of the Source Code You
+ distribute. You may not offer or impose any terms on any Source Code
+ version that alters or restricts the applicable version of this
+ License or the recipients' rights hereunder. However, You may include
+ an additional document offering the additional rights described in
+ Section 3.5.
+
+ 3.2. Availability of Source Code.
+ Any Modification which You create or to which You contribute must be
+ made available in Source Code form under the terms of this License
+ either on the same media as an Executable version or via an accepted
+ Electronic Distribution Mechanism to anyone to whom you made an
+ Executable version available; and if made available via Electronic
+ Distribution Mechanism, must remain available for at least twelve (12)
+ months after the date it initially became available, or at least six
+ (6) months after a subsequent version of that particular Modification
+ has been made available to such recipients. You are responsible for
+ ensuring that the Source Code version remains available even if the
+ Electronic Distribution Mechanism is maintained by a third party.
+
+ 3.3. Description of Modifications.
+ You must cause all Covered Code to which You contribute to contain a
+ file documenting the changes You made to create that Covered Code and
+ the date of any change. You must include a prominent statement that
+ the Modification is derived, directly or indirectly, from Original
+ Code provided by the Initial Developer and including the name of the
+ Initial Developer in (a) the Source Code, and (b) in any notice in an
+ Executable version or related documentation in which You describe the
+ origin or ownership of the Covered Code.
+
+ 3.4. Intellectual Property Matters
+ (a) Third Party Claims.
+ If Contributor has knowledge that a license under a third party's
+ intellectual property rights is required to exercise the rights
+ granted by such Contributor under Sections 2.1 or 2.2,
+ Contributor must include a text file with the Source Code
+ distribution titled "LEGAL" which describes the claim and the
+ party making the claim in sufficient detail that a recipient will
+ know whom to contact. If Contributor obtains such knowledge after
+ the Modification is made available as described in Section 3.2,
+ Contributor shall promptly modify the LEGAL file in all copies
+ Contributor makes available thereafter and shall take other steps
+ (such as notifying appropriate mailing lists or newsgroups)
+ reasonably calculated to inform those who received the Covered
+ Code that new knowledge has been obtained.
+
+ (b) Contributor APIs.
+ If Contributor's Modifications include an application programming
+ interface and Contributor has knowledge of patent licenses which
+ are reasonably necessary to implement that API, Contributor must
+ also include this information in the LEGAL file.
+
+ (c) Representations.
+ Contributor represents that, except as disclosed pursuant to
+ Section 3.4(a) above, Contributor believes that Contributor's
+ Modifications are Contributor's original creation(s) and/or
+ Contributor has sufficient rights to grant the rights conveyed by
+ this License.
+
+ 3.5. Required Notices.
+ You must duplicate the notice in Exhibit A in each file of the Source
+ Code. If it is not possible to put such notice in a particular Source
+ Code file due to its structure, then You must include such notice in a
+ location (such as a relevant directory) where a user would be likely
+ to look for such a notice. If You created one or more Modification(s)
+ You may add your name as a Contributor to the notice described in
+ Exhibit A. You must also duplicate this License in any documentation
+ for the Source Code where You describe recipients' rights or ownership
+ rights relating to Covered Code. You may choose to offer, and to
+ charge a fee for, warranty, support, indemnity or liability
+ obligations to one or more recipients of Covered Code. However, You
+ may do so only on Your own behalf, and not on behalf of the Initial
+ Developer or any Contributor. You must make it absolutely clear than
+ any such warranty, support, indemnity or liability obligation is
+ offered by You alone, and You hereby agree to indemnify the Initial
+ Developer and every Contributor for any liability incurred by the
+ Initial Developer or such Contributor as a result of warranty,
+ support, indemnity or liability terms You offer.
+
+ 3.6. Distribution of Executable Versions.
+ You may distribute Covered Code in Executable form only if the
+ requirements of Section 3.1-3.5 have been met for that Covered Code,
+ and if You include a notice stating that the Source Code version of
+ the Covered Code is available under the terms of this License,
+ including a description of how and where You have fulfilled the
+ obligations of Section 3.2. The notice must be conspicuously included
+ in any notice in an Executable version, related documentation or
+ collateral in which You describe recipients' rights relating to the
+ Covered Code. You may distribute the Executable version of Covered
+ Code or ownership rights under a license of Your choice, which may
+ contain terms different from this License, provided that You are in
+ compliance with the terms of this License and that the license for the
+ Executable version does not attempt to limit or alter the recipient's
+ rights in the Source Code version from the rights set forth in this
+ License. If You distribute the Executable version under a different
+ license You must make it absolutely clear that any terms which differ
+ from this License are offered by You alone, not by the Initial
+ Developer or any Contributor. You hereby agree to indemnify the
+ Initial Developer and every Contributor for any liability incurred by
+ the Initial Developer or such Contributor as a result of any such
+ terms You offer.
+
+ 3.7. Larger Works.
+ You may create a Larger Work by combining Covered Code with other code
+ not governed by the terms of this License and distribute the Larger
+ Work as a single product. In such a case, You must make sure the
+ requirements of this License are fulfilled for the Covered Code.
+
+4. Inability to Comply Due to Statute or Regulation.
+
+ If it is impossible for You to comply with any of the terms of this
+ License with respect to some or all of the Covered Code due to
+ statute, judicial order, or regulation then You must: (a) comply with
+ the terms of this License to the maximum extent possible; and (b)
+ describe the limitations and the code they affect. Such description
+ must be included in the LEGAL file described in Section 3.4 and must
+ be included with all distributions of the Source Code. Except to the
+ extent prohibited by statute or regulation, such description must be
+ sufficiently detailed for a recipient of ordinary skill to be able to
+ understand it.
+
+5. Application of this License.
+
+ This License applies to code to which the Initial Developer has
+ attached the notice in Exhibit A and to related Covered Code.
+
+6. Versions of the License.
+
+ 6.1. New Versions.
+ Netscape Communications Corporation ("Netscape") may publish revised
+ and/or new versions of the License from time to time. Each version
+ will be given a distinguishing version number.
+
+ 6.2. Effect of New Versions.
+ Once Covered Code has been published under a particular version of the
+ License, You may always continue to use it under the terms of that
+ version. You may also choose to use such Covered Code under the terms
+ of any subsequent version of the License published by Netscape. No one
+ other than Netscape has the right to modify the terms applicable to
+ Covered Code created under this License.
+
+ 6.3. Derivative Works.
+ If You create or use a modified version of this License (which you may
+ only do in order to apply it to code which is not already Covered Code
+ governed by this License), You must (a) rename Your license so that
+ the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
+ "MPL", "NPL" or any confusingly similar phrase do not appear in your
+ license (except to note that your license differs from this License)
+ and (b) otherwise make it clear that Your version of the license
+ contains terms which differ from the Mozilla Public License and
+ Netscape Public License. (Filling in the name of the Initial
+ Developer, Original Code or Contributor in the notice described in
+ Exhibit A shall not of themselves be deemed to be modifications of
+ this License.)
+
+7. DISCLAIMER OF WARRANTY.
+
+ COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+ WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+ WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
+ DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
+ THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
+ IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
+ YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
+ COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
+ OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
+ ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+8. TERMINATION.
+
+ 8.1. This License and the rights granted hereunder will terminate
+ automatically if You fail to comply with terms herein and fail to cure
+ such breach within 30 days of becoming aware of the breach. All
+ sublicenses to the Covered Code which are properly granted shall
+ survive any termination of this License. Provisions which, by their
+ nature, must remain in effect beyond the termination of this License
+ shall survive.
+
+ 8.2. If You initiate litigation by asserting a patent infringement
+ claim (excluding declatory judgment actions) against Initial Developer
+ or a Contributor (the Initial Developer or Contributor against whom
+ You file such action is referred to as "Participant") alleging that:
+
+ (a) such Participant's Contributor Version directly or indirectly
+ infringes any patent, then any and all rights granted by such
+ Participant to You under Sections 2.1 and/or 2.2 of this License
+ shall, upon 60 days notice from Participant terminate prospectively,
+ unless if within 60 days after receipt of notice You either: (i)
+ agree in writing to pay Participant a mutually agreeable reasonable
+ royalty for Your past and future use of Modifications made by such
+ Participant, or (ii) withdraw Your litigation claim with respect to
+ the Contributor Version against such Participant. If within 60 days
+ of notice, a reasonable royalty and payment arrangement are not
+ mutually agreed upon in writing by the parties or the litigation claim
+ is not withdrawn, the rights granted by Participant to You under
+ Sections 2.1 and/or 2.2 automatically terminate at the expiration of
+ the 60 day notice period specified above.
+
+ (b) any software, hardware, or device, other than such Participant's
+ Contributor Version, directly or indirectly infringes any patent, then
+ any rights granted to You by such Participant under Sections 2.1(b)
+ and 2.2(b) are revoked effective as of the date You first made, used,
+ sold, distributed, or had made, Modifications made by that
+ Participant.
+
+ 8.3. If You assert a patent infringement claim against Participant
+ alleging that such Participant's Contributor Version directly or
+ indirectly infringes any patent where such claim is resolved (such as
+ by license or settlement) prior to the initiation of patent
+ infringement litigation, then the reasonable value of the licenses
+ granted by such Participant under Sections 2.1 or 2.2 shall be taken
+ into account in determining the amount or value of any payment or
+ license.
+
+ 8.4. In the event of termination under Sections 8.1 or 8.2 above,
+ all end user license agreements (excluding distributors and resellers)
+ which have been validly granted by You or any distributor hereunder
+ prior to termination shall survive termination.
+
+9. LIMITATION OF LIABILITY.
+
+ UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+ (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
+ DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,
+ OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR
+ ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
+ CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
+ WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
+ COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
+ INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
+ LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
+ RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
+ PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
+ EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
+ THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
+
+10. U.S. GOVERNMENT END USERS.
+
+ The Covered Code is a "commercial item," as that term is defined in
+ 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
+ software" and "commercial computer software documentation," as such
+ terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
+ C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),
+ all U.S. Government End Users acquire Covered Code with only those
+ rights set forth herein.
+
+11. MISCELLANEOUS.
+
+ This License represents the complete agreement concerning subject
+ matter hereof. If any provision of this License is held to be
+ unenforceable, such provision shall be reformed only to the extent
+ necessary to make it enforceable. This License shall be governed by
+ California law provisions (except to the extent applicable law, if
+ any, provides otherwise), excluding its conflict-of-law provisions.
+ With respect to disputes in which at least one party is a citizen of,
+ or an entity chartered or registered to do business in the United
+ States of America, any litigation relating to this License shall be
+ subject to the jurisdiction of the Federal Courts of the Northern
+ District of California, with venue lying in Santa Clara County,
+ California, with the losing party responsible for costs, including
+ without limitation, court costs and reasonable attorneys' fees and
+ expenses. The application of the United Nations Convention on
+ Contracts for the International Sale of Goods is expressly excluded.
+ Any law or regulation which provides that the language of a contract
+ shall be construed against the drafter shall not apply to this
+ License.
+
+12. RESPONSIBILITY FOR CLAIMS.
+
+ As between Initial Developer and the Contributors, each party is
+ responsible for claims and damages arising, directly or indirectly,
+ out of its utilization of rights under this License and You agree to
+ work with Initial Developer and Contributors to distribute such
+ responsibility on an equitable basis. Nothing herein is intended or
+ shall be deemed to constitute any admission of liability.
+
+13. MULTIPLE-LICENSED CODE.
+
+ Initial Developer may designate portions of the Covered Code as
+ "Multiple-Licensed". "Multiple-Licensed" means that the Initial
+ Developer permits you to utilize portions of the Covered Code under
+ Your choice of the MPL or the alternative licenses, if any, specified
+ by the Initial Developer in the file described in Exhibit A.
+
+EXHIBIT A -Mozilla Public License.

+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL. It is numbered 2
+because it goes with version 2 of the ordinary GPL.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Library General Public License, applies to some specially
+designated Free Software Foundation software, and to any other libraries
+whose authors decide to use it. You can use it for your libraries, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you
+wish), that you receive source code or can get it if you want it, that you
+can change the software or use pieces of it in new free programs; and that
+you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These
+restrictions translate to certain responsibilities for you if you
+distribute copies of the library, or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link a program with the library, you must provide complete object files to
+the recipients so that they can relink them with the library, after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+Our method of protecting your rights has two steps: (1) copyright the
+library, and (2) offer you this license which gives you legal permission to
+copy, distribute and/or modify the library.
+
+Also, for each distributor's protection, we want to make certain that
+everyone understands that there is no warranty for this free library. If
+the library is modified by someone else and passed on, we want its
+recipients to know that what they have is not the original version, so that
+any problems introduced by others will not reflect on the original authors'
+reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that companies distributing free software will
+individually obtain patent licenses, thus in effect transforming the
+program into proprietary software. To prevent this, we have made it clear
+that any patent must be licensed for everyone's free use or not licensed at
+all.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License, which was designed for utility programs. This
+license, the GNU Library General Public License, applies to certain
+designated libraries. This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it. Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program. However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+Because of this blurred distinction, using the ordinary General Public
+License for libraries did not effectively promote software sharing, because
+most developers did not use the libraries. We concluded that weaker
+conditions might promote sharing better.
+
+However, unrestricted linking of non-free programs would deprive the users
+of those programs of all benefit from the free status of the libraries
+themselves. This Library General Public License is intended to permit
+developers of non-free programs to use free libraries, while preserving
+your freedom as a user of such programs to change the free libraries that
+are incorporated in them. (We have not seen how to achieve this as regards
+changes in header files, but we have achieved it as regards changes in the
+actual functions of the Library.) The hope is that this will lead to faster
+development of free libraries.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, while the latter only works together with the
+library.
+
+Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library which contains a
+ notice placed by the copyright holder or other authorized party saying
+ it may be distributed under the terms of this Library General Public
+ License (also called "this License"). Each licensee is addressed as
+ "you".
+
+ A "library" means a collection of software functions and/or data
+ prepared so as to be conveniently linked with application programs
+ (which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work which
+ has been distributed under these terms. A "work based on the Library"
+ means either the Library or any derivative work under copyright law:
+ that is to say, a work containing the Library or a portion of it, either
+ verbatim or with modifications and/or translated straightforwardly into
+ another language. (Hereinafter, translation is included without
+ limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for making
+ modifications to it. For a library, complete source code means all the
+ source code for all modules it contains, plus any associated interface
+ definition files, plus the scripts used to control compilation and
+ installation of the library.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of running
+ a program using the Library is not restricted, and output from such a
+ program is covered only if its contents constitute a work based on the
+ Library (independent of the use of the Library in a tool for writing
+ it). Whether that is true depends on what the Library does and what the
+ program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+ source code as you receive it, in any medium, provided that you
+ conspicuously and appropriately publish on each copy an appropriate
+ copyright notice and disclaimer of warranty; keep intact all the notices
+ that refer to this License and to the absence of any warranty; and
+ distribute a copy of this License along with the Library.
+
+ You may charge a fee for the physical act of transferring a copy, and
+ you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+ thus forming a work based on the Library, and copy and distribute such
+ modifications or work under the terms of Section 1 above, provided that
+ you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices stating
+ that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no charge to
+ all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a table
+ of data to be supplied by an application program that uses the
+ facility, other than as an argument passed when the facility is
+ invoked, then you must make a good faith effort to ensure that, in
+ the event an application does not supply such function or table, the
+ facility still operates, and performs whatever part of its purpose
+ remains meaningful.
+
+ (For example, a function in a library to compute square roots has a
+ purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must be
+ optional: if the application does not supply it, the square root
+ function must still compute square roots.)
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Library, and
+ can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based on
+ the Library, the distribution of the whole must be on the terms of this
+ License, whose permissions for other licensees extend to the entire
+ whole, and thus to each and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Library.
+
+ In addition, mere aggregation of another work not based on the Library
+ with the Library (or with a work based on the Library) on a volume of a
+ storage or distribution medium does not bring the other work under the
+ scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+ License instead of this License to a given copy of the Library. To do
+ this, you must alter all the notices that refer to this License, so that
+ they refer to the ordinary GNU General Public License, version 2,
+ instead of to this License. (If a newer version than version 2 of the
+ ordinary GNU General Public License has appeared, then you can specify
+ that version instead if you wish.) Do not make any other change in these
+ notices.
+
+ Once this change is made in a given copy, it is irreversible for that
+ copy, so the ordinary GNU General Public License applies to all
+ subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of the
+ Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+ it, under Section 2) in object code or executable form under the terms
+ of Sections 1 and 2 above provided that you accompany it with the
+ complete corresponding machine-readable source code, which must be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy from a
+ designated place, then offering equivalent access to copy the source
+ code from the same place satisfies the requirement to distribute the
+ source code, even though third parties are not compelled to copy the
+ source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+ is designed to work with the Library by being compiled or linked with
+ it, is called a "work that uses the Library". Such a work, in isolation,
+ is not a derivative work of the Library, and therefore falls outside the
+ scope of this License.
+
+ However, linking a "work that uses the Library" with the Library creates
+ an executable that is a derivative of the Library (because it contains
+ portions of the Library), rather than a "work that uses the
+ library". The executable is therefore covered by this License. Section 6
+ states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+ that is part of the Library, the object code for the work may be a
+ derivative work of the Library even though the source code is
+ not. Whether this is true is especially significant if the work can be
+ linked without the Library, or if the work is itself a library. The
+ threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data structure
+ layouts and accessors, and small macros and small inline functions (ten
+ lines or less in length), then the use of the object file is
+ unrestricted, regardless of whether it is legally a derivative
+ work. (Executables containing this object code plus portions of the
+ Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+ distribute the object code for the work under the terms of Section
+ 6. Any executables containing that work also fall under Section 6,
+ whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also compile or link a
+ "work that uses the Library" with the Library to produce a work
+ containing portions of the Library, and distribute that work under terms
+ of your choice, provided that the terms permit modification of the work
+ for the customer's own use and reverse engineering for debugging such
+ modifications.
+
+ You must give prominent notice with each copy of the work that the
+ Library is used in it and that the Library and its use are covered by
+ this License. You must supply a copy of this License. If the work during
+ execution displays copyright notices, you must include the copyright
+ notice for the Library among them, as well as a reference directing the
+ user to the copy of this License. Also, you must do one of these things:
+
+ a) Accompany the work with the complete corresponding machine-readable
+ source code for the Library including whatever changes were used in
+ the work (which must be distributed under Sections 1 and 2 above);
+ and, if the work is an executable linked with the Library, with the
+ complete machine-readable "work that uses the Library", as object
+ code and/or source code, so that the user can modify the Library and
+ then relink to produce a modified executable containing the modified
+ Library. (It is understood that the user who changes the contents of
+ definitions files in the Library will not necessarily be able to
+ recompile the application to use the modified definitions.)
+
+ b) Accompany the work with a written offer, valid for at least three
+ years, to give the same user the materials specified in Subsection
+ 6a, above, for a charge no more than the cost of performing this
+ distribution.
+
+ c) If distribution of the work is made by offering access to copy from a
+ designated place, offer equivalent access to copy the above specified
+ materials from the same place.
+
+ d) Verify that the user has already received a copy of these materials
+ or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the Library"
+ must include any data and utility programs needed for reproducing the
+ executable from it. However, as a special exception, the source code
+ distributed need not include anything that is normally distributed (in
+ either source or binary form) with the major components (compiler,
+ kernel, and so on) of the operating system on which the executable runs,
+ unless that component itself accompanies the executable.
+
+ It may happen that this requirement contradicts the license restrictions
+ of other proprietary libraries that do not normally accompany the
+ operating system. Such a contradiction means you cannot use both them
+ and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+ side-by-side in a single library together with other library facilities
+ not covered by this License, and distribute such a combined library,
+ provided that the separate distribution of the work based on the Library
+ and of the other library facilities is otherwise permitted, and provided
+ that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work based on
+ the Library, uncombined with any other library facilities. This must
+ be distributed under the terms of the Sections above.
+
+ b) Give prominent notice with the combined library of the fact that part
+ of it is a work based on the Library, and explaining where to find
+ the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+ Library except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, link with, or distribute the
+ Library is void, and will automatically terminate your rights under this
+ License. However, parties who have received copies, or rights, from you
+ under this License will not have their licenses terminated so long as
+ such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+ it. However, nothing else grants you permission to modify or distribute
+ the Library or its derivative works. These actions are prohibited by law
+ if you do not accept this License. Therefore, by modifying or
+ distributing the Library (or any work based on the Library), you
+ indicate your acceptance of this License to do so, and all its terms and
+ conditions for copying, distributing or modifying the Library or works
+ based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+ Library), the recipient automatically receives a license from the
+ original licensor to copy, distribute, link with or modify the Library
+ subject to these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted
+ herein. You are not responsible for enforcing compliance by third
+ parties to this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Library at all. For example, if a patent license
+ would not permit royalty-free redistribution of the Library by all
+ those who receive copies directly or indirectly through you, then the
+ only way you could satisfy both it and this License would be to refrain
+ entirely from distribution of the Library.
+
+ If any portion of this section is held invalid or unenforceable under
+ any particular circumstance, the balance of the section is intended to
+ apply, and the section as a whole is intended to apply in other
+ circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system which is implemented
+ by public license practices. Many people have made generous
+ contributions to the wide range of software distributed through that
+ system in reliance on consistent application of that system; it is up
+ to the author/donor to decide if he or she is willing to distribute
+ software through any other system and a licensee cannot impose that
+ choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+ countries either by patents or by copyrighted interfaces, the original
+ copyright holder who places the Library under this License may add an
+ explicit geographical distribution limitation excluding those
+ countries, so that distribution is permitted only in or among countries
+ not thus excluded. In such case, this License incorporates the
+ limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+ the Library General Public License from time to time. Such new versions
+ will be similar in spirit to the present version, but may differ in
+ detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Library
+ specifies a version number of this License which applies to it and "any
+ later version", you have the option of following the terms and
+ conditions either of that version or of any later version published by
+ the Free Software Foundation. If the Library does not specify a license
+ version number, you may choose any version ever published by the Free
+ Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+ programs whose distribution conditions are incompatible with these,
+ write to the author to ask for permission. For software which is
+ copyrighted by the Free Software Foundation, write to the Free Software
+ Foundation; we sometimes make exceptions for this. Our decision will be
+ guided by the two goals of preserving the free status of all
+ derivatives of our free software and of promoting the sharing and reuse
+ of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+ FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+ OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+ PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+ EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+ WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+ ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+ YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+ NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+ REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+ DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+ DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+ (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+ INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+ THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+ OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Library General Public License as published by
+the Free Software Foundation; either version 2 of the License, or (at your
+option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Library General Public
+License for more details.
+
+You should have received a copy of the GNU Library General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in
+the library `Frob' (a library for tweaking knobs) written

+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+ which contains a notice placed by the copyright holder or other
+ authorized party saying it may be distributed under the terms of this
+ Lesser General Public License (also called "this License"). Each
+ licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+ prepared so as to be conveniently linked with application programs
+ (which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work which
+ has been distributed under these terms. A "work based on the Library"
+ means either the Library or any derivative work under copyright law:
+ that is to say, a work containing the Library or a portion of it, either
+ verbatim or with modifications and/or translated straightforwardly into
+ another language. (Hereinafter, translation is included without
+ limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for making
+ modifications to it. For a library, complete source code means all the
+ source code for all modules it contains, plus any associated interface
+ definition files, plus the scripts used to control compilation and
+ installation of the library.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of running
+ a program using the Library is not restricted, and output from such a
+ program is covered only if its contents constitute a work based on the
+ Library (independent of the use of the Library in a tool for writing
+ it). Whether that is true depends on what the Library does and what the
+ program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+ source code as you receive it, in any medium, provided that you
+ conspicuously and appropriately publish on each copy an appropriate
+ copyright notice and disclaimer of warranty; keep intact all the notices
+ that refer to this License and to the absence of any warranty; and
+ distribute a copy of this License along with the Library.
+
+ You may charge a fee for the physical act of transferring a copy, and
+ you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+ thus forming a work based on the Library, and copy and distribute such
+ modifications or work under the terms of Section 1 above, provided that
+ you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices stating
+ that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no charge to
+ all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a table
+ of data to be supplied by an application program that uses the
+ facility, other than as an argument passed when the facility is
+ invoked, then you must make a good faith effort to ensure that, in
+ the event an application does not supply such function or table, the
+ facility still operates, and performs whatever part of its purpose
+ remains meaningful.
+
+ (For example, a function in a library to compute square roots has a
+ purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must be
+ optional: if the application does not supply it, the square root
+ function must still compute square roots.)
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Library, and
+ can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based on
+ the Library, the distribution of the whole must be on the terms of this
+ License, whose permissions for other licensees extend to the entire
+ whole, and thus to each and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Library.
+
+ In addition, mere aggregation of another work not based on the Library
+ with the Library (or with a work based on the Library) on a volume of a
+ storage or distribution medium does not bring the other work under the
+ scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+ License instead of this License to a given copy of the Library. To do
+ this, you must alter all the notices that refer to this License, so that
+ they refer to the ordinary GNU General Public License, version 2,
+ instead of to this License. (If a newer version than version 2 of the
+ ordinary GNU General Public License has appeared, then you can specify
+ that version instead if you wish.) Do not make any other change in these
+ notices.
+
+ Once this change is made in a given copy, it is irreversible for that
+ copy, so the ordinary GNU General Public License applies to all
+ subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of the
+ Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+ it, under Section 2) in object code or executable form under the terms
+ of Sections 1 and 2 above provided that you accompany it with the
+ complete corresponding machine-readable source code, which must be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy from a
+ designated place, then offering equivalent access to copy the source
+ code from the same place satisfies the requirement to distribute the
+ source code, even though third parties are not compelled to copy the
+ source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+ is designed to work with the Library by being compiled or linked with
+ it, is called a "work that uses the Library". Such a work, in isolation,
+ is not a derivative work of the Library, and therefore falls outside the
+ scope of this License.
+
+ However, linking a "work that uses the Library" with the Library creates
+ an executable that is a derivative of the Library (because it contains
+ portions of the Library), rather than a "work that uses the
+ library". The executable is therefore covered by this License. Section 6
+ states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+ that is part of the Library, the object code for the work may be a
+ derivative work of the Library even though the source code is
+ not. Whether this is true is especially significant if the work can be
+ linked without the Library, or if the work is itself a library. The
+ threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data structure
+ layouts and accessors, and small macros and small inline functions (ten
+ lines or less in length), then the use of the object file is
+ unrestricted, regardless of whether it is legally a derivative
+ work. (Executables containing this object code plus portions of the
+ Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+ distribute the object code for the work under the terms of Section
+ 6. Any executables containing that work also fall under Section 6,
+ whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+ "work that uses the Library" with the Library to produce a work
+ containing portions of the Library, and distribute that work under terms
+ of your choice, provided that the terms permit modification of the work
+ for the customer's own use and reverse engineering for debugging such
+ modifications.
+
+ You must give prominent notice with each copy of the work that the
+ Library is used in it and that the Library and its use are covered by
+ this License. You must supply a copy of this License. If the work during
+ execution displays copyright notices, you must include the copyright
+ notice for the Library among them, as well as a reference directing the
+ user to the copy of this License. Also, you must do one of these things:
+
+ a) Accompany the work with the complete corresponding machine-readable
+ source code for the Library including whatever changes were used in
+ the work (which must be distributed under Sections 1 and 2 above);
+ and, if the work is an executable linked with the Library, with the
+ complete machine-readable "work that uses the Library", as object
+ code and/or source code, so that the user can modify the Library and
+ then relink to produce a modified executable containing the modified
+ Library. (It is understood that the user who changes the contents of
+ definitions files in the Library will not necessarily be able to
+ recompile the application to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a copy
+ of the library already present on the user's computer system, rather
+ than copying library functions into the executable, and (2) will
+ operate properly with a modified version of the library, if the user
+ installs one, as long as the modified version is interface-compatible
+ with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at least three
+ years, to give the same user the materials specified in Subsection
+ 6a, above, for a charge no more than the cost of performing this
+ distribution.
+
+ d) If distribution of the work is made by offering access to copy from a
+ designated place, offer equivalent access to copy the above specified
+ materials from the same place.
+
+ e) Verify that the user has already received a copy of these materials
+ or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the Library"
+ must include any data and utility programs needed for reproducing the
+ executable from it. However, as a special exception, the materials to be
+ distributed need not include anything that is normally distributed (in
+ either source or binary form) with the major components (compiler,
+ kernel, and so on) of the operating system on which the executable runs,
+ unless that component itself accompanies the executable.
+
+ It may happen that this requirement contradicts the license restrictions
+ of other proprietary libraries that do not normally accompany the
+ operating system. Such a contradiction means you cannot use both them
+ and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+ side-by-side in a single library together with other library facilities
+ not covered by this License, and distribute such a combined library,
+ provided that the separate distribution of the work based on the Library
+ and of the other library facilities is otherwise permitted, and provided
+ that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work based on
+ the Library, uncombined with any other library facilities. This must
+ be distributed under the terms of the Sections above.
+
+ b) Give prominent notice with the combined library of the fact that part
+ of it is a work based on the Library, and explaining where to find
+ the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+ Library except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, link with, or distribute the
+ Library is void, and will automatically terminate your rights under this
+ License. However, parties who have received copies, or rights, from you
+ under this License will not have their licenses terminated so long as
+ such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+ it. However, nothing else grants you permission to modify or distribute
+ the Library or its derivative works. These actions are prohibited by law
+ if you do not accept this License. Therefore, by modifying or
+ distributing the Library (or any work based on the Library), you
+ indicate your acceptance of this License to do so, and all its terms and
+ conditions for copying, distributing or modifying the Library or works
+ based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+ Library), the recipient automatically receives a license from the
+ original licensor to copy, distribute, link with or modify the Library
+ subject to these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted
+ herein. You are not responsible for enforcing compliance by third
+ parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Library at all. For example, if a patent license
+ would not permit royalty-free redistribution of the Library by all
+ those who receive copies directly or indirectly through you, then the
+ only way you could satisfy both it and this License would be to refrain
+ entirely from distribution of the Library.
+
+ If any portion of this section is held invalid or unenforceable under
+ any particular circumstance, the balance of the section is intended to
+ apply, and the section as a whole is intended to apply in other
+ circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system which is implemented
+ by public license practices. Many people have made generous
+ contributions to the wide range of software distributed through that
+ system in reliance on consistent application of that system; it is up
+ to the author/donor to decide if he or she is willing to distribute
+ software through any other system and a licensee cannot impose that
+ choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+ countries either by patents or by copyrighted interfaces, the original
+ copyright holder who places the Library under this License may add an
+ explicit geographical distribution limitation excluding those
+ countries, so that distribution is permitted only in or among countries
+ not thus excluded. In such case, this License incorporates the
+ limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+ the Lesser General Public License from time to time. Such new versions
+ will be similar in spirit to the present version, but may differ in
+ detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Library
+ specifies a version number of this License which applies to it and "any
+ later version", you have the option of following the terms and
+ conditions either of that version or of any later version published by
+ the Free Software Foundation. If the Library does not specify a license
+ version number, you may choose any version ever published by the Free
+ Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+ programs whose distribution conditions are incompatible with these,
+ write to the author to ask for permission. For software which is
+ copyrighted by the Free Software Foundation, write to the Free Software
+ Foundation; we sometimes make exceptions for this. Our decision will be
+ guided by the two goals of preserving the free status of all
+ derivatives of our free software and of promoting the sharing and reuse
+ of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+ FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+ OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+ PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+ EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+ WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+ ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+ YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+ NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+ REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+ DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+ DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+ (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+ INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+ THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+ OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Lesser General Public License as published by

+your option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License
+for more details.
+
+You should have received a copy of the GNU Lesser General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add
+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in

+ Generate a warning if any W+X mappings are found at boot.
+
+ This is useful for discovering cases where the kernel is leaving
+ W+X mappings after applying NX, as such mappings are a security risk.
+
+ Look for a message in dmesg output like this:
+
+ arm/mm: Checked W+X mappings: passed, no W+X pages found.

+ or like this, if the check failed:
+
+ arm/mm: Checked W+X mappings: FAILED, <N> W+X pages found.
+
+ Note that even if the check fails, your kernel is possibly
+ still fine, as W+X mappings are not a security hole in
+ themselves, what they do is that they make the exploitation
+ of other unfixed kernel bugs easier.
+
+ There is no runtime or memory usage effect of this option
+ once the kernel has booted up - it's a one time check.
