@@ -0,0 +1,117 @@ +irq_domain interrupt number mapping library + +The current design of the Linux kernel uses a single large number +space where each separate IRQ source is assigned a different number. +This is simple when there is only one interrupt controller, but in +systems with multiple interrupt controllers the kernel must ensure +that each one gets assigned non-overlapping allocations of Linux +IRQ numbers. + +The irq_alloc_desc*() and irq_free_desc*() APIs provide allocation of +irq numbers, but they don't provide any support for reverse mapping of +the controller-local IRQ (hwirq) number into the Linux IRQ number +space. + +The irq_domain library adds mapping between hwirq and IRQ numbers on +top of the irq_alloc_desc*() API. An irq_domain to manage mapping is +preferred over interrupt controller drivers open coding their own +reverse mapping scheme. + +irq_domain also implements translation from Device Tree interrupt +specifiers to hwirq numbers, and can be easily extended to support +other IRQ topology data sources. + +=== irq_domain usage === +An interrupt controller driver creates and registers an irq_domain by +calling one of the irq_domain_add_*() functions (each mapping method +has a different allocator function, more on that later). The function +will return a pointer to the irq_domain on success. The caller must +provide the allocator function with an irq_domain_ops structure with +the .map callback populated as a minimum. + +In most cases, the irq_domain will begin empty without any mappings +between hwirq and IRQ numbers. Mappings are added to the irq_domain +by calling irq_create_mapping() which accepts the irq_domain and a +hwirq number as arguments. If a mapping for the hwirq doesn't already +exist then it will allocate a new Linux irq_desc, associate it with +the hwirq, and call the .map() callback so the driver can perform any +required hardware setup. + +When an interrupt is received, irq_find_mapping() function should +be used to find the Linux IRQ number from the hwirq number. + +If the driver has the Linux IRQ number or the irq_data pointer, and +needs to know the associated hwirq number (such as in the irq_chip +callbacks) then it can be directly obtained from irq_data->hwirq. + +=== Types of irq_domain mappings === +There are several mechanisms available for reverse mapping from hwirq +to Linux irq, and each mechanism uses a different allocation function. +Which reverse map type should be used depends on the use case. Each +of the reverse map types are described below: + +==== Linear ==== +irq_domain_add_linear() + +The linear reverse map maintains a fixed size table indexed by the +hwirq number. When a hwirq is mapped, an irq_desc is allocated for +the hwirq, and the IRQ number is stored in the table. + +The Linear map is a good choice when the maximum number of hwirqs is +fixed and a relatively small number (~ < 256). The advantages of this +map are fixed time lookup for IRQ numbers, and irq_descs are only +allocated for in-use IRQs. The disadvantage is that the table must be +as large as the largest possible hwirq number. + +The majority of drivers should use the linear map. + +==== Tree ==== +irq_domain_add_tree() + +The irq_domain maintains a radix tree map from hwirq numbers to Linux +IRQs. When an hwirq is mapped, an irq_desc is allocated and the +hwirq is used as the lookup key for the radix tree. + +The tree map is a good choice if the hwirq number can be very large +since it doesn't need to allocate a table as large as the largest +hwirq number. The disadvantage is that hwirq to IRQ number lookup is +dependent on how many entries are in the table. + +Very few drivers should need this mapping. At the moment, powerpc +iseries is the only user. + +==== No Map ===- +irq_domain_add_nomap() + +The No Map mapping is to be used when the hwirq number is +programmable in the hardware. In this case it is best to program the +Linux IRQ number into the hardware itself so that no mapping is +required. Calling irq_create_direct_mapping() will allocate a Linux +IRQ number and call the .map() callback so that driver can program the +Linux IRQ number into the hardware. + +Most drivers cannot use this mapping. + +==== Legacy ==== +irq_domain_add_legacy() +irq_domain_add_legacy_isa() + +The Legacy mapping is a special case for drivers that already have a +range of irq_descs allocated for the hwirqs. It is used when the +driver cannot be immediately converted to use the linear mapping. For +example, many embedded system board support files use a set of #defines +for IRQ numbers that are passed to struct device registrations. In that +case the Linux IRQ numbers cannot be dynamically assigned and the legacy +mapping should be used. + +The legacy map assumes a contiguous range of IRQ numbers has already +been allocated for the controller and that the IRQ number can be +calculated by adding a fixed offset to the hwirq number, and +visa-versa. The disadvantage is that it requires the interrupt +controller to manage IRQ allocations and it requires an irq_desc to be +allocated for every hwirq, even if it is unused. + +The legacy map should only be used if fixed IRQ mappings must be +supported. For example, ISA controllers would use the legacy map for +mapping Linux IRQs 0-15 so that existing ISA drivers get the correct IRQ +numbers.

(Inode, Bitmap and Longfilenames) +Each of these root nodes holds information like total size of the stored +data and the adressing levels in that specific tree. +If the level value is 0, up to 16 direct blocks can be adressed by each +node. +Level 1 adds an additional indirect adressing level where each indirect +adressing block holds up to blocksize / 4 bytes pointers to data blocks. +Level 2 adds an additional indirect adressig block level (so, already up +to 16 * 256 * 256 = 1048576 blocks that can be adressed by such a tree)a + +Unused block pointers are always set to ~0 - regardless of root node, +indirect adressing blocks or inodes. +Data leaves are always on the lowest level.

(0x2000 is the bootblock size) +The Audi MMI 3G first superblock directly starts at byte 0. +Second superblock position can either be calculated from the superblock +information (total number of filesystem blocks) or by taking the highest +device address, zeroing the last 3 bytes and then substracting 0x1000 from +that address. + +0x1000 is the size reserved for each superblock - regardless of the +blocksize of the filesystem. + +Inodes +------ + +Each object in the filesystem is represented by an inode.

(scheme is the same as the one used for the superblock root nodes) + +The filesize is stored 64bit. Inode counting starts with 1. (whilst long +filename inodes start with 0) + +Directories +----------- + +A directory is a filesystem object and has an inode just like a file. +It is a specially formatted file containing records which associate each +name with an inode number. +'.' inode number points to the directory inode +'..' inode number points to the parent directory inode +Eeach filename record additionally got a filename length field. + +One special case are long filenames or subdirectory names. +These got set a filename length field of 0xff in the corresponding directory +record plus the longfile inode number also stored in that record. +With that longfilename inode number, the longfilename tree can be walked +starting with the superblock longfilename root node pointers. + +Special files +------------- + +Symbolic links are also filesystem objects with inodes. They got a specific +bit in the inode mode field identifying them as symbolic link. +The directory entry file inode pointer points to the target file inode. + +Hard links got an inode, a directory entry, but a specific mode bit set, +no block pointers and the directory file record pointing to the target file +inode. + +Character and block special devices do not exist in QNX as those files +are handled by the QNX kernel/drivers and created in /dev independant of the +underlaying filesystem. + +Long filenames +-------------- + +Long filenames are stored in a seperate adressing tree. The staring point +is the longfilename root node in the active superblock. +Each data block (tree leaves) holds one long filename. That filename is +limited to 510 bytes. The first two starting bytes are used as length field +for the actual filename. +If that structure shall fit for all allowed blocksizes, it is clear why there +is a limit of 510 bytes for the actual filename stored. + +Bitmap +------ + +The qnx6fs filesystem allocation bitmap is stored in a tree under bitmap +root node in the superblock and each bit in the bitmap represents one +filesystem block. +The first block is block 0, which starts 0x1000 after superblock start. +So for a normal qnx6fs 0x3000 (bootblock + superblock) is the physical +address at which block 0 is located. + +Bits at the end of the last bitmap block are set to 1, if the device is +smaller than addressing space in the bitmap. + +Bitmap system area +------------------ + +The bitmap itself is devided into three parts. +First the system area, that is split into two halfs. +Then userspace. + +The requirement for a static, fixed preallocated system area comes from how +qnx6fs deals with writes. +Each superblock got it's own half of the system area. So superblock #1 +always uses blocks from the lower half whilst superblock #2 just writes to +blocks represented by the upper half bitmap system area bits. + +Bitmap blocks, Inode blocks and indirect addressing blocks for those two +tree structures are treated as system blocks. + +The rational behind that is that a write request can work on a new snapshot +(system area of the inactive - resp. lower serial numbered superblock) while +at the same time there is still a complete stable filesystem structer in the +other half of the system area. + +When finished with writing (a sync write is completed, the maximum sync leap +time or a filesystem sync is requested), serial of the previously inactive +superblock atomically is increased and the fs switches over to that - then +stable declared - superblock. + +For all data outside the system area, blocks are just copied while writing.

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 Lesser 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.

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.

This helps us reuse the + kdump infrastructure for dump capture and filtering. +- Unlike phyp dump, userspace tool does not need to refer any sysfs + interface while reading /proc/vmcore. +- Unlike phyp dump, fadump allows user to release all the memory reserved + for dump, with a single operation of echo 1 > /sys/kernel/fadump_release_mem. +- Once enabled through kernel boot parameter, fadump can be + started/stopped through /sys/kernel/fadump_registered interface (see + sysfs files section below) and can be easily integrated with kdump + service start/stop init scripts. + +Comparing with kdump or other strategies, firmware-assisted +dump offers several strong, practical advantages: + +-- Unlike kdump, the system has been reset, and loaded + with a fresh copy of the kernel. In particular, + PCI and I/O devices have been reinitialized and are + in a clean, consistent state. +-- Once the dump is copied out, the memory that held the dump + is immediately available to the running kernel. And therefore, + unlike kdump, fadump doesn't need a 2nd reboot to get back + the system to the production configuration. + +The above can only be accomplished by coordination with, +and assistance from the Power firmware. The procedure is +as follows: + +-- The first kernel registers the sections of memory with the + Power firmware for dump preservation during OS initialization. + These registered sections of memory are reserved by the first + kernel during early boot. + +-- When a system crashes, the Power firmware will save + the low memory (boot memory of size larger of 5% of system RAM + or 256MB) of RAM to the previous registered region. It will + also save system registers, and hardware PTE's. + + NOTE: The term 'boot memory' means size of the low memory chunk + that is required for a kernel to boot successfully when + booted with restricted memory. By default, the boot memory + size will be the larger of 5% of system RAM or 256MB. + Alternatively, user can also specify boot memory size + through boot parameter 'fadump_reserve_mem=' which will + override the default calculated size. Use this option + if default boot memory size is not sufficient for second + kernel to boot successfully. + +-- After the low memory (boot memory) area has been saved, the + firmware will reset PCI and other hardware state. It will + *not* clear the RAM. It will then launch the bootloader, as + normal. + +-- The freshly booted kernel will notice that there is a new + node (ibm,dump-kernel) in the device tree, indicating that + there is crash data available from a previous boot. During + the early boot OS will reserve rest of the memory above + boot memory size effectively booting with restricted memory + size. This will make sure that the second kernel will not + touch any of the dump memory area. + +-- User-space tools will read /proc/vmcore to obtain the contents + of memory, which holds the previous crashed kernel dump in ELF + format. The userspace tools may copy this info to disk, or + network, nas, san, iscsi, etc. as desired. + +-- Once the userspace tool is done saving dump, it will echo + '1' to /sys/kernel/fadump_release_mem to release the reserved + memory back to general use, except the memory required for + next firmware-assisted dump registration. + + e.g. + # echo 1 > /sys/kernel/fadump_release_mem + +Please note that the firmware-assisted dump feature +is only available on Power6 and above systems with recent +firmware versions. + +Implementation details: +---------------------- + +During boot, a check is made to see if firmware supports +this feature on that particular machine. If it does, then +we check to see if an active dump is waiting for us. If yes +then everything but boot memory size of RAM is reserved during +early boot (See Fig. 2). This area is released once we finish +collecting the dump from user land scripts (e.g. kdump scripts) +that are run. If there is dump data, then the +/sys/kernel/fadump_release_mem file is created, and the reserved +memory is held. + +If there is no waiting dump data, then only the memory required +to hold CPU state, HPTE region, boot memory dump and elfcore +header, is reserved at the top of memory (see Fig. 1).

A quick example: + + struct static_key key = STATIC_KEY_INIT_FALSE; + + ... + + if (static_key_false(&key)) + do unlikely code + else + do likely code + + ... + static_key_slow_inc(); + ... + static_key_slow_inc(); + ... + +The static_key_false() branch will be generated into the code with as little +impact to the likely code path as possible. + + +1) Motivation + + +Currently, tracepoints are implemented using a conditional branch. The +conditional check requires checking a global variable for each tracepoint. +Although the overhead of this check is small, it increases when the memory +cache comes under pressure (memory cache lines for these global variables may +be shared with other memory accesses). As we increase the number of tracepoints +in the kernel this overhead may become more of an issue. In addition, +tracepoints are often dormant (disabled) and provide no direct kernel +functionality. Thus, it is highly desirable to reduce their impact as much as +possible. Although tracepoints are the original motivation for this work, other +kernel code paths should be able to make use of the static keys facility. + + +2) Solution + + +gcc (v4.5) adds a new 'asm goto' statement that allows branching to a label: + +http://gcc.gnu.org/ml/gcc-patches/2009-07/msg01556.html + +Using the 'asm goto', we can create branches that are either taken or not taken +by default, without the need to check memory. Then, at run-time, we can patch +the branch site to change the branch direction. + +For example, if we have a simple branch that is disabled by default: + + if (static_key_false(&key)) + printk("I am the true branch\n"); + +Thus, by default the 'printk' will not be emitted. And the code generated will +consist of a single atomic 'no-op' instruction (5 bytes on x86), in the +straight-line code path. When the branch is 'flipped', we will patch the +'no-op' in the straight-line codepath with a 'jump' instruction to the +out-of-line true branch. Thus, changing branch direction is expensive but +branch selection is basically 'free'. That is the basic tradeoff of this +optimization. + +This lowlevel patching mechanism is called 'jump label patching', and it gives +the basis for the static keys facility. + +3) Static key label API, usage and examples: + + +In order to make use of this optimization you must first define a key: + + struct static_key key; + +Which is initialized as: + + struct static_key key = STATIC_KEY_INIT_TRUE; + +or: + + struct static_key key = STATIC_KEY_INIT_FALSE; + +If the key is not initialized, it is default false. The 'struct static_key', +must be a 'global'. That is, it can't be allocated on the stack or dynamically +allocated at run-time. + +The key is then used in code as: + + if (static_key_false(&key)) + do unlikely code + else + do likely code + +Or: + + if (static_key_true(&key)) + do likely code + else + do unlikely code + +A key that is initialized via 'STATIC_KEY_INIT_FALSE', must be used in a +'static_key_false()' construct. Likewise, a key initialized via +'STATIC_KEY_INIT_TRUE' must be used in a 'static_key_true()' construct. A +single key can be used in many branches, but all the branches must match the +way that the key has been initialized. + +The branch(es) can then be switched via: + + static_key_slow_inc(&key); + ... + static_key_slow_dec(&key); + +Thus, 'static_key_slow_inc()' means 'make the branch true', and +'static_key_slow_dec()' means 'make the the branch false' with appropriate +reference counting. For example, if the key is initialized true, a +static_key_slow_dec(), will switch the branch to false. And a subsequent +static_key_slow_inc(), will change the branch back to true. Likewise, if the +key is initialized false, a 'static_key_slow_inc()', will change the branch to +true. And then a 'static_key_slow_dec()', will again make the branch false. + +An example usage in the kernel is the implementation of tracepoints: + + static inline void trace_##name(proto) \ + { \ + if (static_key_false(&__tracepoint_##name.key)) \ + __DO_TRACE(&__tracepoint_##name, \ + TP_PROTO(data_proto), \ + TP_ARGS(data_args), \ + TP_CONDITION(cond)); \ + } + +Tracepoints are disabled by default, and can be placed in performance critical +pieces of the kernel. Thus, by using a static key, the tracepoints can have +absolutely minimal impact when not in use. + + +4) Architecture level code patching interface, 'jump labels' + + +There are a few functions and macros that architectures must implement in order +to take advantage of this optimization.
