Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
"Three fixes and a resulting cleanup for -rc2:
- Andre Przywara reported that he was seeing a warning with the new
cast inside DMA_ERROR_CODE's definition, and fixed the incorrect
use.
- Doug Anderson noticed that kgdb causes a "scheduling while atomic"
bug.
- OMAP5 folk noticed that their Thumb-2 compiled X servers crashed
when enabling support to cover ARMv6 CPUs due to a kernel bug
leaking some conditional context into the signal handler"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: 8425/1: kgdb: Don't try to stop the machine when setting breakpoints
ARM: 8437/1: dma-mapping: fix build warning with new DMA_ERROR_CODE definition
ARM: get rid of needless #if in signal handling code
ARM: fix Thumb2 signal handling when ARMv6 is enabled

+ <title>Introduction</title>
+ <para>
+ The main purpose of the Industrial I/O subsystem (IIO) is to provide
+ support for devices that in some sense perform either analog-to-digital
+ conversion (ADC) or digital-to-analog conversion (DAC) or both. The aim
+ is to fill the gap between the somewhat similar hwmon and input
+ subsystems.
+ Hwmon is directed at low sample rate sensors used to monitor and
+ control the system itself, like fan speed control or temperature
+ measurement. Input is, as its name suggests, focused on human interaction
+ input devices (keyboard, mouse, touchscreen). In some cases there is
+ considerable overlap between these and IIO.

+ Attributes are sysfs files used to expose chip info and also allowing

+ Common attributes are:
+ <itemizedlist>
+ <listitem><filename>name</filename>, description of the physical

+ <sect2 id="iiochannel"> <title> IIO device channels </title>
+!Finclude/linux/iio/iio.h iio_chan_spec structure.
+ <para>
+ An IIO device channel is a representation of a data channel. An
+ IIO device can have one or multiple channels. For example:
+ <itemizedlist>
+ <listitem>
+ a thermometer sensor has one channel representing the
+ temperature measurement.
+ </listitem>
+ <listitem>
+ a light sensor with two channels indicating the measurements in
+ the visible and infrared spectrum.
+ </listitem>
+ <listitem>
+ an accelerometer can have up to 3 channels representing
+ acceleration on X, Y and Z axes.
+ </listitem>
+ </itemizedlist>
+ An IIO channel is described by the <type> struct iio_chan_spec
+ </type>. A thermometer driver for the temperature sensor in the
+ example above would have to describe its channel as follows:
+ <programlisting>
+ static const struct iio_chan_spec temp_channel[] = {
+ {
+ .type = IIO_TEMP,
+ .info_mask_separate = BIT(IIO_CHAN_INFO_PROCESSED),
+ },
+ };
+
+ </programlisting>
+ Channel sysfs attributes exposed to userspace are specified in
+ the form of <emphasis>bitmasks</emphasis>. Depending on their
+ shared info, attributes can be set in one of the following masks:
+ <itemizedlist>
+ <listitem><emphasis>info_mask_separate</emphasis>, attributes will
+ be specific to this channel</listitem>
+ <listitem><emphasis>info_mask_shared_by_type</emphasis>,
+ attributes are shared by all channels of the same type</listitem>
+ <listitem><emphasis>info_mask_shared_by_dir</emphasis>, attributes
+ are shared by all channels of the same direction </listitem>
+ <listitem><emphasis>info_mask_shared_by_all</emphasis>,
+ attributes are shared by all channels</listitem>
+ </itemizedlist>
+ When there are multiple data channels per channel type we have two
+ ways to distinguish between them:
+ <itemizedlist>
+ <listitem> set <emphasis> .modified</emphasis> field of <type>
+ iio_chan_spec</type> to 1. Modifiers are specified using
+ <emphasis>.channel2</emphasis> field of the same
+ <type>iio_chan_spec</type> structure and are used to indicate a
+ physically unique characteristic of the channel such as its direction
+ or spectral response. For example, a light sensor can have two channels,
+ one for infrared light and one for both infrared and visible light.
+ </listitem>
+ <listitem> set <emphasis>.indexed </emphasis> field of
+ <type>iio_chan_spec</type> to 1. In this case the channel is
+ simply another instance with an index specified by the
+ <emphasis>.channel</emphasis> field.
+ </listitem>
+ </itemizedlist>
+ Here is how we can make use of the channel's modifiers:
+ <programlisting>
+ static const struct iio_chan_spec light_channels[] = {
+ {
+ .type = IIO_INTENSITY,
+ .modified = 1,
+ .channel2 = IIO_MOD_LIGHT_IR,
+ .info_mask_separate = BIT(IIO_CHAN_INFO_RAW),
+ .info_mask_shared = BIT(IIO_CHAN_INFO_SAMP_FREQ),
+ },
+ {
+ .type = IIO_INTENSITY,
+ .modified = 1,
+ .channel2 = IIO_MOD_LIGHT_BOTH,
+ .info_mask_separate = BIT(IIO_CHAN_INFO_RAW),
+ .info_mask_shared = BIT(IIO_CHAN_INFO_SAMP_FREQ),
+ },
+ {
+ .type = IIO_LIGHT,
+ .info_mask_separate = BIT(IIO_CHAN_INFO_PROCESSED),
+ .info_mask_shared = BIT(IIO_CHAN_INFO_SAMP_FREQ),
+ },
+
+ }
+ </programlisting>
+ This channel's definition will generate two separate sysfs files
+ for raw data retrieval:
+ <itemizedlist>
+ <listitem>
+ <filename>/sys/bus/iio/iio:deviceX/in_intensity_ir_raw</filename>
+ </listitem>
+ <listitem>
+ <filename>/sys/bus/iio/iio:deviceX/in_intensity_both_raw</filename>
+ </listitem>
+ </itemizedlist>
+ one file for processed data:
+ <itemizedlist>
+ <listitem>
+ <filename>/sys/bus/iio/iio:deviceX/in_illuminance_input
+ </filename>
+ </listitem>
+ </itemizedlist>
+ and one shared sysfs file for sampling frequency:
+ <itemizedlist>
+ <listitem>
+ <filename>/sys/bus/iio/iio:deviceX/sampling_frequency.
+ </filename>
+ </listitem>
+ </itemizedlist>
+ </para>
+ <para>
+ Here is how we can make use of the channel's indexing:
+ <programlisting>
+ static const struct iio_chan_spec light_channels[] = {
+ {
+ .type = IIO_VOLTAGE,
+ .indexed = 1,
+ .channel = 0,
+ .info_mask_separate = BIT(IIO_CHAN_INFO_RAW),
+ },
+ {
+ .type = IIO_VOLTAGE,
+ .indexed = 1,
+ .channel = 1,
+ .info_mask_separate = BIT(IIO_CHAN_INFO_RAW),
+ },
+ }
+ </programlisting>
+ This will generate two separate attributes files for raw data
+ retrieval:
+ <itemizedlist>
+ <listitem>
+ <filename>/sys/bus/iio/devices/iio:deviceX/in_voltage0_raw</filename>,
+ representing voltage measurement for channel 0.
+ </listitem>
+ <listitem>
+ <filename>/sys/bus/iio/devices/iio:deviceX/in_voltage1_raw</filename>,
+ representing voltage measurement for channel 1.

+ For example, a driver for a 3-axis accelerometer with 12 bit

+ +---+---+---+---+---+---+---+---+
+ </programlisting>
+
+ will have the following scan element type for each axis:
+ <programlisting>
+ $ cat /sys/bus/iio/devices/iio:device0/scan_elements/in_accel_y_type
+ le:s12/16>>4
+ </programlisting>
+ A user space application will interpret data samples read from the
+ buffer as two byte little endian signed data, that needs a 4 bits
+ right shift before masking out the 12 valid bits of data.
+ </para>
+ <para>
+ For implementing buffer support a driver should initialize the following

+ u8 realbits;
+ u8 storagebits;
+ u8 shift;

+ </programlisting>
+ The driver implementing the accelerometer described above will
+ have the following channel definition:
+ <programlisting>
+ struct struct iio_chan_spec accel_channels[] = {
+ {
+ .type = IIO_ACCEL,
+ .modified = 1,

+ </para>
+ <para>
+ Here <emphasis> scan_index </emphasis> defines the order in which

+ In many situations it is useful for a driver to be able to
+ capture data based on some external event (trigger) as opposed
+ to periodically polling for data. An IIO trigger can be provided
+ by a device driver that also has an IIO device based on hardware
+ generated events (e.g. data ready or threshold exceeded) or
+ provided by a separate driver from an independent interrupt
+ source (e.g. GPIO line connected to some external system, timer

+ also it may be completely unrelated to the sensor itself.

+Abstract:
-trace_state
+This document describes the functions and the interfaces of the method
+tracing facility.
+
+1. Functionalities and usage examples:
+
+ ACPICA provides method tracing capability. And two functions are
+ currently implemented using this capability.
+
+ A. Log reducer
+ ACPICA subsystem provides debugging outputs when CONFIG_ACPI_DEBUG is
+ enabled. The debugging messages which are deployed via
+ ACPI_DEBUG_PRINT() macro can be reduced at 2 levels - per-component
+ level (known as debug layer, configured via
+ /sys/module/acpi/parameters/debug_layer) and per-type level (known as
+ debug level, configured via /sys/module/acpi/parameters/debug_level).
+
+ But when the particular layer/level is applied to the control method
+ evaluations, the quantity of the debugging outputs may still be too
+ large to be put into the kernel log buffer. The idea thus is worked out
+ to only enable the particular debug layer/level (normally more detailed)
+ logs when the control method evaluation is started, and disable the
+ detailed logging when the control method evaluation is stopped.
+
+ The following command examples illustrate the usage of the "log reducer"
+ functionality:
+ a. Filter out the debug layer/level matched logs when control methods
+ are being evaluated:
+ # cd /sys/module/acpi/parameters
+ # echo "0xXXXXXXXX" > trace_debug_layer
+ # echo "0xYYYYYYYY" > trace_debug_level
+ # echo "enable" > trace_state
+ b. Filter out the debug layer/level matched logs when the specified
+ control method is being evaluated:
+ # cd /sys/module/acpi/parameters
+ # echo "0xXXXXXXXX" > trace_debug_layer
+ # echo "0xYYYYYYYY" > trace_debug_level
+ # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+ # echo "method" > /sys/module/acpi/parameters/trace_state
+ c. Filter out the debug layer/level matched logs when the specified
+ control method is being evaluated for the first time:
+ # cd /sys/module/acpi/parameters
+ # echo "0xXXXXXXXX" > trace_debug_layer
+ # echo "0xYYYYYYYY" > trace_debug_level
+ # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+ # echo "method-once" > /sys/module/acpi/parameters/trace_state
+ Where:
+ 0xXXXXXXXX/0xYYYYYYYY: Refer to Documentation/acpi/debug.txt for
+ possible debug layer/level masking values.
+ \PPPP.AAAA.TTTT.HHHH: Full path of a control method that can be found
+ in the ACPI namespace. It needn't be an entry
+ of a control method evaluation.
+
+ B. AML tracer
+
+ There are special log entries added by the method tracing facility at
+ the "trace points" the AML interpreter starts/stops to execute a control
+ method, or an AML opcode. Note that the format of the log entries are
+ subject to change:
+ [ 0.186427] exdebug-0398 ex_trace_point : Method Begin [0xf58394d8:\_SB.PCI0.LPCB.ECOK] execution.

+ Developers can utilize these special log entries to track the AML
+ interpretion, thus can aid issue debugging and performance tuning. Note
+ that, as the "AML tracer" logs are implemented via ACPI_DEBUG_PRINT()
+ macro, CONFIG_ACPI_DEBUG is also required to be enabled for enabling
+ "AML tracer" logs.
+
+ The following command examples illustrate the usage of the "AML tracer"
+ functionality:
+ a. Filter out the method start/stop "AML tracer" logs when control
+ methods are being evaluated:
+ # cd /sys/module/acpi/parameters
+ # echo "0x80" > trace_debug_layer
+ # echo "0x10" > trace_debug_level
+ # echo "enable" > trace_state
+ b. Filter out the method start/stop "AML tracer" when the specified
+ control method is being evaluated:
+ # cd /sys/module/acpi/parameters
+ # echo "0x80" > trace_debug_layer
+ # echo "0x10" > trace_debug_level
+ # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+ # echo "method" > trace_state
+ c. Filter out the method start/stop "AML tracer" logs when the specified
+ control method is being evaluated for the first time:
+ # cd /sys/module/acpi/parameters
+ # echo "0x80" > trace_debug_layer
+ # echo "0x10" > trace_debug_level
+ # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+ # echo "method-once" > trace_state
+ d. Filter out the method/opcode start/stop "AML tracer" when the
+ specified control method is being evaluated:
+ # cd /sys/module/acpi/parameters
+ # echo "0x80" > trace_debug_layer
+ # echo "0x10" > trace_debug_level
+ # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+ # echo "opcode" > trace_state
+ e. Filter out the method/opcode start/stop "AML tracer" when the
+ specified control method is being evaluated for the first time:
+ # cd /sys/module/acpi/parameters
+ # echo "0x80" > trace_debug_layer
+ # echo "0x10" > trace_debug_level
+ # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+ # echo "opcode-opcode" > trace_state
+
+ Note that all above method tracing facility related module parameters can
+ be used as the boot parameters, for example:
+ acpi.trace_debug_layer=0x80 acpi.trace_debug_level=0x10 \
+ acpi.trace_method_name=\_SB.LID0._LID acpi.trace_state=opcode-once
+
+2. Interface descriptions:
+
+ All method tracing functions can be configured via ACPI module
+ parameters that are accessible at /sys/module/acpi/parameters/:
+
+ trace_method_name
+ The full path of the AML method that the user wants to trace.
+ Note that the full path shouldn't contain the trailing "_"s in its
+ name segments but may contain "\" to form an absolute path.
+
+ trace_debug_layer
+ The temporary debug_layer used when the tracing feature is enabled.
+ Using ACPI_EXECUTER (0x80) by default, which is the debug_layer
+ used to match all "AML tracer" logs.
+
+ trace_debug_level
+ The temporary debug_level used when the tracing feature is enabled.
+ Using ACPI_LV_TRACE_POINT (0x10) by default, which is the
+ debug_level used to match all "AML tracer" logs.
+
+ trace_state
The status of the tracing feature.
-
- "enabled" means this feature is enabled
- and the AML method is traced every time it's executed.
-
- "1" means this feature is enabled and the AML method
- will only be traced during the next execution.
-
- "disabled" means this feature is disabled.
- Users can enable/disable this debug tracing feature by
- "echo string > /sys/module/acpi/parameters/trace_state".
- "string" should be one of "enable", "disable" and "1".
+ Users can enable/disable this debug tracing feature by executing
+ the following command:
+ # echo string > /sys/module/acpi/parameters/trace_state
+ Where "string" should be one of the followings:
+ "disable"
+ Disable the method tracing feature.
+ "enable"
+ Enable the method tracing feature.
+ ACPICA debugging messages matching
+ "trace_debug_layer/trace_debug_level" during any method
+ execution will be logged.
+ "method"
+ Enable the method tracing feature.
+ ACPICA debugging messages matching
+ "trace_debug_layer/trace_debug_level" during method execution
+ of "trace_method_name" will be logged.
+ "method-once"
+ Enable the method tracing feature.
+ ACPICA debugging messages matching
+ "trace_debug_layer/trace_debug_level" during method execution
+ of "trace_method_name" will be logged only once.
+ "opcode"
+ Enable the method tracing feature.
+ ACPICA debugging messages matching
+ "trace_debug_layer/trace_debug_level" during method/opcode
+ execution of "trace_method_name" will be logged.
+ "opcode-once"
+ Enable the method tracing feature.
+ ACPICA debugging messages matching
+ "trace_debug_layer/trace_debug_level" during method/opcode
+ execution of "trace_method_name" will be logged only once.
+ Note that, the difference between the "enable" and other feature
+ enabling options are:
+ 1. When "enable" is specified, since
+ "trace_debug_layer/trace_debug_level" shall apply to all control
+ method evaluations, after configuring "trace_state" to "enable",
+ "trace_method_name" will be reset to NULL.
+ 2. When "method/opcode" is specified, if
+ "trace_method_name" is NULL when "trace_state" is configured to
+ these options, the "trace_debug_layer/trace_debug_level" will
+ apply to all control method evaluations.

+Adding a New System Call
+========================
+
+This document describes what's involved in adding a new system call to the
+Linux kernel, over and above the normal submission advice in
+Documentation/SubmittingPatches.
+
+
+System Call Alternatives
+------------------------
+
+The first thing to consider when adding a new system call is whether one of
+the alternatives might be suitable instead. Although system calls are the
+most traditional and most obvious interaction points between userspace and the
+kernel, there are other possibilities -- choose what fits best for your
+interface.
+
+ - If the operations involved can be made to look like a filesystem-like
+ object, it may make more sense to create a new filesystem or device. This
+ also makes it easier to encapsulate the new functionality in a kernel module
+ rather than requiring it to be built into the main kernel.
+ - If the new functionality involves operations where the kernel notifies
+ userspace that something has happened, then returning a new file
+ descriptor for the relevant object allows userspace to use
+ poll/select/epoll to receive that notification.
+ - However, operations that don't map to read(2)/write(2)-like operations
+ have to be implemented as ioctl(2) requests, which can lead to a
+ somewhat opaque API.
+ - If you're just exposing runtime system information, a new node in sysfs
+ (see Documentation/filesystems/sysfs.txt) or the /proc filesystem may be
+ more appropriate. However, access to these mechanisms requires that the
+ relevant filesystem is mounted, which might not always be the case (e.g.
+ in a namespaced/sandboxed/chrooted environment). Avoid adding any API to
+ debugfs, as this is not considered a 'production' interface to userspace.
+ - If the operation is specific to a particular file or file descriptor, then
+ an additional fcntl(2) command option may be more appropriate. However,
+ fcntl(2) is a multiplexing system call that hides a lot of complexity, so
+ this option is best for when the new function is closely analogous to
+ existing fcntl(2) functionality, or the new functionality is very simple
+ (for example, getting/setting a simple flag related to a file descriptor).
+ - If the operation is specific to a particular task or process, then an
+ additional prctl(2) command option may be more appropriate. As with
+ fcntl(2), this system call is a complicated multiplexor so is best reserved
+ for near-analogs of existing prctl() commands or getting/setting a simple
+ flag related to a process.
+
+
+Designing the API: Planning for Extension
+-----------------------------------------
+
+A new system call forms part of the API of the kernel, and has to be supported
+indefinitely. As such, it's a very good idea to explicitly discuss the
+interface on the kernel mailing list, and it's important to plan for future
+extensions of the interface.
+
+(The syscall table is littered with historical examples where this wasn't done,
+together with the corresponding follow-up system calls -- eventfd/eventfd2,
+dup2/dup3, inotify_init/inotify_init1, pipe/pipe2, renameat/renameat2 -- so
+learn from the history of the kernel and plan for extensions from the start.)
+
+For simpler system calls that only take a couple of arguments, the preferred
+way to allow for future extensibility is to include a flags argument to the
+system call. To make sure that userspace programs can safely use flags
+between kernel versions, check whether the flags value holds any unknown
+flags, and reject the system call (with EINVAL) if it does:
+
+ if (flags & ~(THING_FLAG1 | THING_FLAG2 | THING_FLAG3))
+ return -EINVAL;
+
+(If no flags values are used yet, check that the flags argument is zero.)
+
+For more sophisticated system calls that involve a larger number of arguments,
+it's preferred to encapsulate the majority of the arguments into a structure
+that is passed in by pointer. Such a structure can cope with future extension
+by including a size argument in the structure:
+
+ struct xyzzy_params {
+ u32 size; /* userspace sets p->size = sizeof(struct xyzzy_params) */
+ u32 param_1;
+ u64 param_2;
+ u64 param_3;
+ };
+
+As long as any subsequently added field, say param_4, is designed so that a
+zero value gives the previous behaviour, then this allows both directions of
+version mismatch:
+
+ - To cope with a later userspace program calling an older kernel, the kernel
+ code should check that any memory beyond the size of the structure that it
+ expects is zero (effectively checking that param_4 == 0).
+ - To cope with an older userspace program calling a newer kernel, the kernel
+ code can zero-extend a smaller instance of the structure (effectively
+ setting param_4 = 0).
+
+See perf_event_open(2) and the perf_copy_attr() function (in
+kernel/events/core.c) for an example of this approach.
+
+
+Designing the API: Other Considerations
+---------------------------------------
+
+If your new system call allows userspace to refer to a kernel object, it
+should use a file descriptor as the handle for that object -- don't invent a
+new type of userspace object handle when the kernel already has mechanisms and
+well-defined semantics for using file descriptors.
+
+If your new xyzzy(2) system call does return a new file descriptor, then the
+flags argument should include a value that is equivalent to setting O_CLOEXEC
+on the new FD. This makes it possible for userspace to close the timing
+window between xyzzy() and calling fcntl(fd, F_SETFD, FD_CLOEXEC), where an
+unexpected fork() and execve() in another thread could leak a descriptor to
+the exec'ed program. (However, resist the temptation to re-use the actual value
+of the O_CLOEXEC constant, as it is architecture-specific and is part of a
+numbering space of O_* flags that is fairly full.)
+
+If your system call returns a new file descriptor, you should also consider
+what it means to use the poll(2) family of system calls on that file
+descriptor. Making a file descriptor ready for reading or writing is the
+normal way for the kernel to indicate to userspace that an event has
+occurred on the corresponding kernel object.
+
+If your new xyzzy(2) system call involves a filename argument:
+
+ int sys_xyzzy(const char __user *path, ..., unsigned int flags);
+
+you should also consider whether an xyzzyat(2) version is more appropriate:
+
+ int sys_xyzzyat(int dfd, const char __user *path, ..., unsigned int flags);
+
+This allows more flexibility for how userspace specifies the file in question;
+in particular it allows userspace to request the functionality for an
+already-opened file descriptor using the AT_EMPTY_PATH flag, effectively giving
+an fxyzzy(3) operation for free:
+
+ - xyzzyat(AT_FDCWD, path, ..., 0) is equivalent to xyzzy(path,...)
+ - xyzzyat(fd, "", ..., AT_EMPTY_PATH) is equivalent to fxyzzy(fd, ...)
+
+(For more details on the rationale of the *at() calls, see the openat(2) man
+page; for an example of AT_EMPTY_PATH, see the statat(2) man page.)
+
+If your new xyzzy(2) system call involves a parameter describing an offset
+within a file, make its type loff_t so that 64-bit offsets can be supported
+even on 32-bit architectures.
+
+If your new xyzzy(2) system call involves privileged functionality, it needs
+to be governed by the appropriate Linux capability bit (checked with a call to
+capable()), as described in the capabilities(7) man page. Choose an existing
+capability bit that governs related functionality, but try to avoid combining
+lots of only vaguely related functions together under the same bit, as this
+goes against capabilities' purpose of splitting the power of root. In
+particular, avoid adding new uses of the already overly-general CAP_SYS_ADMIN
+capability.
+
+If your new xyzzy(2) system call manipulates a process other than the calling
+process, it should be restricted (using a call to ptrace_may_access()) so that
+only a calling process with the same permissions as the target process, or
+with the necessary capabilities, can manipulate the target process.
+
+Finally, be aware that some non-x86 architectures have an easier time if
+system call parameters that are explicitly 64-bit fall on odd-numbered
+arguments (i.e. parameter 1, 3, 5), to allow use of contiguous pairs of 32-bit
+registers. (This concern does not apply if the arguments are part of a
+structure that's passed in by pointer.)
+
+
+Proposing the API
+-----------------
+
+To make new system calls easy to review, it's best to divide up the patchset
+into separate chunks. These should include at least the following items as
+distinct commits (each of which is described further below):
+
+ - The core implementation of the system call, together with prototypes,
+ generic numbering, Kconfig changes and fallback stub implementation.
+ - Wiring up of the new system call for one particular architecture, usually
+ x86 (including all of x86_64, x86_32 and x32).
+ - A demonstration of the use of the new system call in userspace via a
+ selftest in tools/testing/selftests/.
+ - A draft man-page for the new system call, either as plain text in the
+ cover letter, or as a patch to the (separate) man-pages repository.
+
+New system call proposals, like any change to the kernel's API, should always
+be cc'ed to linux-api@vger.kernel.org.
+
+
+Generic System Call Implementation
+----------------------------------
+
+The main entry point for your new xyzzy(2) system call will be called
+sys_xyzzy(), but you add this entry point with the appropriate
+SYSCALL_DEFINEn() macro rather than explicitly. The 'n' indicates the number
+of arguments to the system call, and the macro takes the system call name
+followed by the (type, name) pairs for the parameters as arguments. Using
+this macro allows metadata about the new system call to be made available for
+other tools.
+
+The new entry point also needs a corresponding function prototype, in
+include/linux/syscalls.h, marked as asmlinkage to match the way that system
+calls are invoked:
+
+ asmlinkage long sys_xyzzy(...);
+
+Some architectures (e.g. x86) have their own architecture-specific syscall
+tables, but several other architectures share a generic syscall table. Add your
+new system call to the generic list by adding an entry to the list in
+include/uapi/asm-generic/unistd.h:
+
+ #define __NR_xyzzy 292
+ __SYSCALL(__NR_xyzzy, sys_xyzzy)
+
+Also update the __NR_syscalls count to reflect the additional system call, and
+note that if multiple new system calls are added in the same merge window,
+your new syscall number may get adjusted to resolve conflicts.
+
+The file kernel/sys_ni.c provides a fallback stub implementation of each system
+call, returning -ENOSYS. Add your new system call here too:
+
+ cond_syscall(sys_xyzzy);
+
+Your new kernel functionality, and the system call that controls it, should
+normally be optional, so add a CONFIG option (typically to init/Kconfig) for
+it. As usual for new CONFIG options:
+
+ - Include a description of the new functionality and system call controlled
+ by the option.
+ - Make the option depend on EXPERT if it should be hidden from normal users.
+ - Make any new source files implementing the function dependent on the CONFIG
+ option in the Makefile (e.g. "obj-$(CONFIG_XYZZY_SYSCALL) += xyzzy.c").
+ - Double check that the kernel still builds with the new CONFIG option turned
+ off.
+
+To summarize, you need a commit that includes:
+
+ - CONFIG option for the new function, normally in init/Kconfig
+ - SYSCALL_DEFINEn(xyzzy, ...) for the entry point
+ - corresponding prototype in include/linux/syscalls.h
+ - generic table entry in include/uapi/asm-generic/unistd.h
+ - fallback stub in kernel/sys_ni.c
+
+
+x86 System Call Implementation
+------------------------------
+
+To wire up your new system call for x86 platforms, you need to update the
+master syscall tables. Assuming your new system call isn't special in some
+way (see below), this involves a "common" entry (for x86_64 and x32) in
+arch/x86/entry/syscalls/syscall_64.tbl:
+
+ 333 common xyzzy sys_xyzzy
+
+and an "i386" entry in arch/x86/entry/syscalls/syscall_32.tbl:
+
+ 380 i386 xyzzy sys_xyzzy
+
+Again, these numbers are liable to be changed if there are conflicts in the
+relevant merge window.
+
+
+Compatibility System Calls (Generic)
+------------------------------------
+
+For most system calls the same 64-bit implementation can be invoked even when
+the userspace program is itself 32-bit; even if the system call's parameters
+include an explicit pointer, this is handled transparently.
+
+However, there are a couple of situations where a compatibility layer is
+needed to cope with size differences between 32-bit and 64-bit.
+
+The first is if the 64-bit kernel also supports 32-bit userspace programs, and
+so needs to parse areas of (__user) memory that could hold either 32-bit or
+64-bit values. In particular, this is needed whenever a system call argument
+is:
+
+ - a pointer to a pointer
+ - a pointer to a struct containing a pointer (e.g. struct iovec __user *)
+ - a pointer to a varying sized integral type (time_t, off_t, long, ...)
+ - a pointer to a struct containing a varying sized integral type.
+
+The second situation that requires a compatibility layer is if one of the
+system call's arguments has a type that is explicitly 64-bit even on a 32-bit
+architecture, for example loff_t or __u64. In this case, a value that arrives
+at a 64-bit kernel from a 32-bit application will be split into two 32-bit
+values, which then need to be re-assembled in the compatibility layer.
+
+(Note that a system call argument that's a pointer to an explicit 64-bit type
+does *not* need a compatibility layer; for example, splice(2)'s arguments of
+type loff_t __user * do not trigger the need for a compat_ system call.)
+
+The compatibility version of the system call is called compat_sys_xyzzy(), and
+is added with the COMPAT_SYSCALL_DEFINEn() macro, analogously to
+SYSCALL_DEFINEn. This version of the implementation runs as part of a 64-bit
+kernel, but expects to receive 32-bit parameter values and does whatever is
+needed to deal with them. (Typically, the compat_sys_ version converts the
+values to 64-bit versions and either calls on to the sys_ version, or both of
+them call a common inner implementation function.)
+
+The compat entry point also needs a corresponding function prototype, in
+include/linux/compat.h, marked as asmlinkage to match the way that system
+calls are invoked:
+
+ asmlinkage long compat_sys_xyzzy(...);
+
+If the system call involves a structure that is laid out differently on 32-bit
+and 64-bit systems, say struct xyzzy_args, then the include/linux/compat.h
+header file should also include a compat version of the structure (struct
+compat_xyzzy_args) where each variable-size field has the appropriate compat_
+type that corresponds to the type in struct xyzzy_args. The
+compat_sys_xyzzy() routine can then use this compat_ structure to parse the
+arguments from a 32-bit invocation.
+
+For example, if there are fields:
+
+ struct xyzzy_args {
+ const char __user *ptr;
+ __kernel_long_t varying_val;
+ u64 fixed_val;
+ /* ... */
+ };
+
+in struct xyzzy_args, then struct compat_xyzzy_args would have:
+
+ struct compat_xyzzy_args {
+ compat_uptr_t ptr;
+ compat_long_t varying_val;
+ u64 fixed_val;
+ /* ... */
+ };
+
+The generic system call list also needs adjusting to allow for the compat
+version; the entry in include/uapi/asm-generic/unistd.h should use
+__SC_COMP rather than __SYSCALL:
+
+ #define __NR_xyzzy 292
+ __SC_COMP(__NR_xyzzy, sys_xyzzy, compat_sys_xyzzy)
+
+To summarize, you need:
+
+ - a COMPAT_SYSCALL_DEFINEn(xyzzy, ...) for the compat entry point
+ - corresponding prototype in include/linux/compat.h
+ - (if needed) 32-bit mapping struct in include/linux/compat.h
+ - instance of __SC_COMP not __SYSCALL in include/uapi/asm-generic/unistd.h
+
+
+Compatibility System Calls (x86)
+--------------------------------
+
+To wire up the x86 architecture of a system call with a compatibility version,
+the entries in the syscall tables need to be adjusted.
+
+First, the entry in arch/x86/entry/syscalls/syscall_32.tbl gets an extra
+column to indicate that a 32-bit userspace program running on a 64-bit kernel
+should hit the compat entry point:
+
+ 380 i386 xyzzy sys_xyzzy compat_sys_xyzzy
+
+Second, you need to figure out what should happen for the x32 ABI version of
+the new system call. There's a choice here: the layout of the arguments
+should either match the 64-bit version or the 32-bit version.
+
+If there's a pointer-to-a-pointer involved, the decision is easy: x32 is
+ILP32, so the layout should match the 32-bit version, and the entry in
+arch/x86/entry/syscalls/syscall_64.tbl is split so that x32 programs hit the
+compatibility wrapper:
+
+ 333 64 xyzzy sys_xyzzy
+ ...
+ 555 x32 xyzzy compat_sys_xyzzy
+
+If no pointers are involved, then it is preferable to re-use the 64-bit system
+call for the x32 ABI (and consequently the entry in
+arch/x86/entry/syscalls/syscall_64.tbl is unchanged).
+
+In either case, you should check that the types involved in your argument
+layout do indeed map exactly from x32 (-mx32) to either the 32-bit (-m32) or
+64-bit (-m64) equivalents.
+
+
+System Calls Returning Elsewhere
+--------------------------------
+
+For most system calls, once the system call is complete the user program
+continues exactly where it left off -- at the next instruction, with the
+stack the same and most of the registers the same as before the system call,
+and with the same virtual memory space.
+
+However, a few system calls do things differently. They might return to a
+different location (rt_sigreturn) or change the memory space (fork/vfork/clone)
+or even architecture (execve/execveat) of the program.
+
+To allow for this, the kernel implementation of the system call may need to
+save and restore additional registers to the kernel stack, allowing complete
+control of where and how execution continues after the system call.
+
+This is arch-specific, but typically involves defining assembly entry points
+that save/restore additional registers and invoke the real system call entry
+point.
+
+For x86_64, this is implemented as a stub_xyzzy entry point in
+arch/x86/entry/entry_64.S, and the entry in the syscall table
+(arch/x86/entry/syscalls/syscall_64.tbl) is adjusted to match:
+
+ 333 common xyzzy stub_xyzzy
+
+The equivalent for 32-bit programs running on a 64-bit kernel is normally
+called stub32_xyzzy and implemented in arch/x86/entry/entry_64_compat.S,
+with the corresponding syscall table adjustment in
+arch/x86/entry/syscalls/syscall_32.tbl:
+
+ 380 i386 xyzzy sys_xyzzy stub32_xyzzy
+
+If the system call needs a compatibility layer (as in the previous section)
+then the stub32_ version needs to call on to the compat_sys_ version of the
+system call rather than the native 64-bit version. Also, if the x32 ABI
+implementation is not common with the x86_64 version, then its syscall
+table will also need to invoke a stub that calls on to the compat_sys_
+version.
+
+For completeness, it's also nice to set up a mapping so that user-mode Linux
+still works -- its syscall table will reference stub_xyzzy, but the UML build
+doesn't include arch/x86/entry/entry_64.S implementation (because UML
+simulates registers etc). Fixing this is as simple as adding a #define to
+arch/x86/um/sys_call_table_64.c:
+
+ #define stub_xyzzy sys_xyzzy
+
+
+Other Details
+-------------
+
+Most of the kernel treats system calls in a generic way, but there is the
+occasional exception that may need updating for your particular system call.
+
+The audit subsystem is one such special case; it includes (arch-specific)
+functions that classify some special types of system call -- specifically
+file open (open/openat), program execution (execve/exeveat) or socket
+multiplexor (socketcall) operations. If your new system call is analogous to
+one of these, then the audit system should be updated.
+
+More generally, if there is an existing system call that is analogous to your
+new system call, it's worth doing a kernel-wide grep for the existing system
+call to check there are no other special cases.
+
+
+Testing
+-------
+
+A new system call should obviously be tested; it is also useful to provide
+reviewers with a demonstration of how user space programs will use the system
+call. A good way to combine these aims is to include a simple self-test
+program in a new directory under tools/testing/selftests/.
+
+For a new system call, there will obviously be no libc wrapper function and so
+the test will need to invoke it using syscall(); also, if the system call
+involves a new userspace-visible structure, the corresponding header will need
+to be installed to compile the test.
+
+Make sure the selftest runs successfully on all supported architectures. For
+example, check that it works when compiled as an x86_64 (-m64), x86_32 (-m32)
+and x32 (-mx32) ABI program.
+
+For more extensive and thorough testing of new functionality, you should also
+consider adding tests to the Linux Test Project, or to the xfstests project
+for filesystem-related changes.

+--------
+
+All new system calls should come with a complete man page, ideally using groff
+markup, but plain text will do. If groff is used, it's helpful to include a
+pre-rendered ASCII version of the man page in the cover email for the
+patchset, for the convenience of reviewers.
+
+The man page should be cc'ed to linux-man@vger.kernel.org
+For more details, see https://www.kernel.org/doc/man-pages/patches.html

+ TI Keystone Linux Overview
+ --------------------------
+
+Introduction
+------------
+Keystone range of SoCs are based on ARM Cortex-A15 MPCore Processors
+and c66x DSP cores. This document describes essential information required
+for users to run Linux on Keystone based EVMs from Texas Instruments.
+
+Following SoCs & EVMs are currently supported:-
+
+------------ K2HK SoC and EVM --------------------------------------------------
+
+a.k.a Keystone 2 Hawking/Kepler SoC
+TCI6636K2H & TCI6636K2K: See documentation at

+K2E - 66AK2E05: See documentation at
+ http://www.ti.com/product/66AK2E05/technicaldocuments
+
+EVM:
+https://www.einfochips.com/index.php/partnerships/texas-instruments/k2e-evm.html
+
+------------ K2L SoC and EVM ---------------------------------------------------
+

+K2L - TCI6630K2L: See documentation at
+ http://www.ti.com/product/TCI6630K2L/technicaldocuments
+EVM:
+https://www.einfochips.com/index.php/partnerships/texas-instruments/k2l-evm.html
+
+Configuration
+-------------
+
+All of the K2 SoCs/EVMs share a common defconfig, keystone_defconfig and same
+image is used to boot on individual EVMs. The platform configuration is
+specified through DTS. Following are the DTS used:-
+ K2HK EVM : k2hk-evm.dts
+ K2E EVM : k2e-evm.dts
+ K2L EVM : k2l-evm.dts
+
+The device tree documentation for the keystone machines are located at
+ Documentation/devicetree/bindings/arm/keystone/keystone.txt
+
+Known issues & workaround
+-------------------------
+
+Some of the device drivers used on keystone are re-used from that from
+DaVinci and other TI SoCs. These device drivers may use clock APIs directly.
+Some of the keystone specific drivers such as netcp uses run time power
+management API instead to enable clock. As this API has limitations on
+keystone, following workaround is needed to boot Linux.
+
+ Add 'clk_ignore_unused' to the bootargs env variable in u-boot. Otherwise
+ clock frameworks will try to disable clocks that are unused and disable
+ the hardware. This is because netcp related power domain and clock
+ domains are enabled in u-boot as run time power management API currently
+ doesn't enable clocks for netcp due to a limitation. This workaround is
+ expected to be removed in the future when proper API support becomes
+ available. Until then, this work around is needed.

+ Process Number Controller
+ =========================
+
+Abstract
+--------
+
+The process number controller is used to allow a cgroup hierarchy to stop any
+new tasks from being fork()'d or clone()'d after a certain limit is reached.
+
+Since it is trivial to hit the task limit without hitting any kmemcg limits in
+place, PIDs are a fundamental resource. As such, PID exhaustion must be
+preventable in the scope of a cgroup hierarchy by allowing resource limiting of
+the number of tasks in a cgroup.
+
+Usage
+-----
+
+In order to use the `pids` controller, set the maximum number of tasks in
+pids.max (this is not available in the root cgroup for obvious reasons). The
+number of processes currently in the cgroup is given by pids.current.
+
+Organisational operations are not blocked by cgroup policies, so it is possible
+to have pids.current > pids.max. This can be done by either setting the limit to
+be smaller than pids.current, or attaching enough processes to the cgroup such
+that pids.current > pids.max. However, it is not possible to violate a cgroup
+policy through fork() or clone(). fork() and clone() will return -EAGAIN if the
+creation of a new process would cause a cgroup policy to be violated.
+
+To set a cgroup to have no limit, set pids.max to "max". This is the default for
+all new cgroups (N.B. that PID limits are hierarchical, so the most stringent
+limit in the hierarchy is followed).
+
+pids.current tracks all child cgroup hierarchies, so parent/pids.current is a
+superset of parent/child/pids.current.
+
+Example
+-------
+
+First, we mount the pids controller:
+# mkdir -p /sys/fs/cgroup/pids
+# mount -t cgroup -o pids none /sys/fs/cgroup/pids
+
+Then we create a hierarchy, set limits and attach processes to it:
+# mkdir -p /sys/fs/cgroup/pids/parent/child
+# echo 2 > /sys/fs/cgroup/pids/parent/pids.max
+# echo $$ > /sys/fs/cgroup/pids/parent/cgroup.procs
+# cat /sys/fs/cgroup/pids/parent/pids.current
+2
+#
+
+It should be noted that attempts to overcome the set limit (2 in this case) will
+fail:
+
+# cat /sys/fs/cgroup/pids/parent/pids.current
+2
+# ( /bin/echo "Here's some processes for you." | cat )
+sh: fork: Resource temporary unavailable
+#
+
+Even if we migrate to a child cgroup (which doesn't have a set limit), we will
+not be able to overcome the most stringent limit in the hierarchy (in this case,
+parent's):
+
+# echo $$ > /sys/fs/cgroup/pids/parent/child/cgroup.procs
+# cat /sys/fs/cgroup/pids/parent/pids.current
+2
+# cat /sys/fs/cgroup/pids/parent/child/pids.current
+2
+# cat /sys/fs/cgroup/pids/parent/child/pids.max
+max
+# ( /bin/echo "Here's some processes for you." | cat )
+sh: fork: Resource temporary unavailable
+#
+
+We can set a limit that is smaller than pids.current, which will stop any new
+processes from being forked at all (note that the shell itself counts towards
+pids.current):
+
+# echo 1 > /sys/fs/cgroup/pids/parent/pids.max
+# /bin/echo "We can't even spawn a single process now."
+sh: fork: Resource temporary unavailable
+# echo 0 > /sys/fs/cgroup/pids/parent/pids.max
+# /bin/echo "We can't even spawn a single process now."
+sh: fork: Resource temporary unavailable

-5-3-2. cpuset
+5-3-2. Control Knobs
+
+- Settings for a single feature should generally be implemented in a
+ single file.
+
+- In general, the root cgroup should be exempt from resource control
+ and thus shouldn't have resource control knobs.
+
+- If a controller implements ratio based resource distribution, the
+ control knob should be named "weight" and have the range [1, 10000]
+ and 100 should be the default value. The values are chosen to allow
+ enough and symmetric bias in both directions while keeping it
+ intuitive (the default is 100%).
+
+- If a controller implements an absolute resource guarantee and/or
+ limit, the control knobs should be named "min" and "max"
+ respectively. If a controller implements best effort resource
+ gurantee and/or limit, the control knobs should be named "low" and
+ "high" respectively.
+
+ In the above four control files, the special token "max" should be
+ used to represent upward infinity for both reading and writing.
+
+- If a setting has configurable default value and specific overrides,
+ the default settings should be keyed with "default" and appear as
+ the first entry in the file. Specific entries can use "default" as
+ its value to indicate inheritance of the default value.
+
+
+5-4. Per-Controller Changes
+
+5-4-1. io
+
+- blkio is renamed to io. The interface is overhauled anyway. The
+ new name is more in line with the other two major controllers, cpu
+ and memory, and better suited given that it may be used for cgroup
+ writeback without involving block layer.
+
+- Everything including stat is always hierarchical making separate
+ recursive stat files pointless and, as no internal node can have
+ tasks, leaf weights are meaningless. The operation model is
+ simplified and the interface is overhauled accordingly.
+
+ io.stat
+
+ The stat file. The reported stats are from the point where
+ bio's are issued to request_queue. The stats are counted

+Discard Support
+---------------
+The implementation of discard support among hardware vendors varies.
+When a block is discarded, some storage devices will return zeroes when
+the block is read. These devices set the 'discard_zeroes_data'
+attribute. Other devices will return random data. Confusingly, some
+devices that advertise 'discard_zeroes_data' will not reliably return
+zeroes when discarded blocks are read! Since RAID 4/5/6 uses blocks
+from a number of devices to calculate parity blocks and (for performance
+reasons) relies on 'discard_zeroes_data' being reliable, it is important
+that the devices be consistent. Blocks may be discarded in the middle
+of a RAID 4/5/6 stripe and if subsequent read results are not
+consistent, the parity blocks may be calculated differently at any time;
+making the parity blocks useless for redundancy. It is important to
+understand how your hardware behaves with discards if you are going to
+enable discards with RAID 4/5/6.
+
+Since the behavior of storage devices is unreliable in this respect,
+even when reporting 'discard_zeroes_data', by default RAID 4/5/6
+discard support is disabled -- this ensures data integrity at the
+expense of losing some performance.
+
+Storage devices that properly support 'discard_zeroes_data' are
+increasingly whitelisted in the kernel and can thus be trusted.
+
+For trusted devices, the following dm-raid module parameter can be set
+to safely enable discard support for RAID 4/5/6:
+ 'devices_handle_discards_safely'

+NVIDIA Tegra124 DFLL FCPU clocksource
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The DFLL IP block on Tegra is a root clocksource designed for clocking
+the fast CPU cluster. It consists of a free-running voltage controlled
+oscillator connected to the CPU voltage rail (VDD_CPU), and a closed loop
+control module that will automatically adjust the VDD_CPU voltage by
+communicating with an off-chip PMIC either via an I2C bus or via PWM signals.
+Currently only the I2C mode is supported by these bindings.
+
+Required properties:
+- compatible : should be "nvidia,tegra124-dfll"
+- reg : Defines the following set of registers, in the order listed:
+ - registers for the DFLL control logic.
+ - registers for the I2C output logic.
+ - registers for the integrated I2C master controller.
+ - look-up table RAM for voltage register values.
+- interrupts: Should contain the DFLL block interrupt.
+- clocks: Must contain an entry for each entry in clock-names.
+ See clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+ - soc: Clock source for the DFLL control logic.
+ - ref: The closed loop reference clock
+ - i2c: Clock source for the integrated I2C master.
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - dvco: Reset control for the DFLL DVCO.
+- #clock-cells: Must be 0.
+- clock-output-names: Name of the clock output.
+- vdd-cpu-supply: Regulator for the CPU voltage rail that the DFLL
+ hardware will start controlling. The regulator will be queried for
+ the I2C register, control values and supported voltages.
+
+Required properties for the control loop parameters:
+- nvidia,sample-rate: Sample rate of the DFLL control loop.
+- nvidia,droop-ctrl: See the register CL_DVFS_DROOP_CTRL in the TRM.
+- nvidia,force-mode: See the field DFLL_PARAMS_FORCE_MODE in the TRM.
+- nvidia,cf: Numeric value, see the field DFLL_PARAMS_CF_PARAM in the TRM.
+- nvidia,ci: Numeric value, see the field DFLL_PARAMS_CI_PARAM in the TRM.
+- nvidia,cg: Numeric value, see the field DFLL_PARAMS_CG_PARAM in the TRM.
+
+Optional properties for the control loop parameters:
+- nvidia,cg-scale: Boolean value, see the field DFLL_PARAMS_CG_SCALE in the TRM.

+* Rockchip RK3368 Clock and Reset Unit
+
+The RK3368 clock controller generates and supplies clock to various
+controllers within the SoC and also implements a reset controller for SoC
+peripherals.
+
+Required Properties:
+
+- compatible: should be "rockchip,rk3368-cru"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+Optional Properties:
+
+- rockchip,grf: phandle to the syscon managing the "general register files"
+ If missing, pll rates are not changeable, due to the missing pll lock status.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/rk3368-cru.h headers and can be
+used in device tree sources. Similar macros exist for the reset sources in
+these files.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "xin24m" - crystal input - required,
+ - "xin32k" - rtc clock - optional,
+ - "ext_i2s" - external I2S clock - optional,
+ - "ext_gmac" - external GMAC clock - optional
+ - "ext_hsadc" - external HSADC clock - optional,
+ - "ext_isp" - external ISP clock - optional,
+ - "ext_jtag" - external JTAG clock - optional
+ - "ext_vip" - external VIP clock - optional,
+ - "usbotg_out" - output clock of the pll in the otg phy
+

+Clock bindings for ST-Ericsson Ux500 clocks
+
+Required properties :
+- compatible : shall contain only one of the following:
+ "stericsson,u8500-clks"
+ "stericsson,u8540-clks"
+ "stericsson,u9540-clks"
+- reg : shall contain base register location and length for
+ CLKRST1, 2, 3, 5, and 6 in an array. Note the absence of
+ CLKRST4, which does not exist.
+
+Required subnodes:
+- prcmu-clock: a subnode with one clock cell for PRCMU (power,
+ reset, control unit) clocks. The cell indicates which PRCMU
+ clock in the prcmu-clock node the consumer wants to use.
+- prcc-periph-clock: a subnode with two clock cells for
+ PRCC (programmable reset- and clock controller) peripheral clocks.
+ The first cell indicates which PRCC block the consumer
+ wants to use, possible values are 1, 2, 3, 5, 6. The second
+ cell indicates which clock inside the PRCC block it wants,
+ possible values are 0 thru 31.
+- prcc-kernel-clock: a subnode with two clock cells for
+ PRCC (programmable reset- and clock controller) kernel clocks
+ The first cell indicates which PRCC block the consumer
+ wants to use, possible values are 1, 2, 3, 5, 6. The second
+ cell indicates which clock inside the PRCC block it wants,
+ possible values are 0 thru 31.
+- rtc32k-clock: a subnode with zero clock cells for the 32kHz
+ RTC clock.
+- smp-twd-clock: a subnode for the ARM SMP Timer Watchdog cluster
+ with zero clock cells.
+
+Example:
+
+clocks {
+ compatible = "stericsson,u8500-clks";
+ /*

+Register-based I2C Bus Mux
+
+This binding describes an I2C bus multiplexer that uses a single register
+to route the I2C signals.
+
+Required properties:
+- compatible: i2c-mux-reg
+- i2c-parent: The phandle of the I2C bus that this multiplexer's master-side

+* Standard I2C mux properties. See mux.txt in this directory.
+* I2C child bus nodes. See mux.txt in this directory.
+
+Optional properties:
+- reg: this pair of <offset size> specifies the register to control the mux.
+ The <offset size> depends on its parent node. It can be any memory-mapped
+ address. The size must be either 1, 2, or 4 bytes. If reg is omitted, the
+ resource of this device will be used.
+- little-endian: The existence indicates the register is in little endian.
+- big-endian: The existence indicates the register is in big endian.
+ If both little-endian and big-endian are omitted, the endianness of the
+ CPU will be used.
+- write-only: The existence indicates the register is write-only.
+- idle-state: value to set the muxer to when idle. When no value is
+ given, it defaults to the last value used.
+
+Whenever an access is made to a device on a child bus, the value set
+in the revelant node's reg property will be output to the register.
+
+If an idle state is defined, using the idle-state (optional) property,
+whenever an access is not being made to a device on a child bus, the
+register will be set according to the idle value.
+
+If an idle state is not defined, the most recently used value will be
+left programmed into the register.

+Generic device tree bindings for I2C busses
+===========================================
+
+This document describes generic bindings which can be used to describe I2C
+busses in a device tree.
+
+Required properties
+-------------------
+
+- #address-cells - should be <1>. Read more about addresses below.
+- #size-cells - should be <0>.
+- compatible - name of I2C bus controller following generic names
+ recommended practice.
+
+For other required properties e.g. to describe register sets,
+clocks, etc. check the binding documentation of the specific driver.
+
+The cells properties above define that an address of children of an I2C bus
+are described by a single value. This is usually a 7 bit address. However,
+flags can be attached to the address. I2C_TEN_BIT_ADDRESS is used to mark a 10
+bit address. It is needed to avoid the ambiguity between e.g. a 7 bit address
+of 0x50 and a 10 bit address of 0x050 which, in theory, can be on the same bus.
+Another flag is I2C_OWN_SLAVE_ADDRESS to mark addresses on which we listen to
+be devices ourselves.
+
+Optional properties
+-------------------
+
+These properties may not be supported by all drivers. However, if a driver
+wants to support one of the below features, it should adapt the bindings below.
+
+- clock-frequency - frequency of bus clock in Hz.
+- wakeup-source - device can be used as a wakeup source.
+
+- interrupts - interrupts used by the device.
+- interrupt-names - "irq" and "wakeup" names are recognized by I2C core,
+ other names are left to individual drivers.
+
+Binding may contain optional "interrupts" property, describing interrupts
+used by the device. I2C core will assign "irq" interrupt (or the very first
+interrupt if not using interrupt names) as primary interrupt for the slave.
+
+Also, if device is marked as a wakeup source, I2C core will set up "wakeup"
+interrupt for the device. If "wakeup" interrupt name is not present in the
+binding, then primary interrupt will be used as wakeup interrupt.

+This document describes the generic device tree binding for MSI controllers and
+their master(s).
+
+Message Signaled Interrupts (MSIs) are a class of interrupts generated by a
+write to an MMIO address.
+
+MSIs were originally specified by PCI (and are used with PCIe), but may also be
+used with other busses, and hence a mechanism is required to relate devices on
+those busses to the MSI controllers which they are capable of using,
+potentially including additional information.
+
+MSIs are distinguished by some combination of:
+
+- The doorbell (the MMIO address written to).
+
+ Devices may be configured by software to write to arbitrary doorbells which
+ they can address. An MSI controller may feature a number of doorbells.
+
+- The payload (the value written to the doorbell).
+
+ Devices may be configured to write an arbitrary payload chosen by software.
+ MSI controllers may have restrictions on permitted payloads.
+
+- Sideband information accompanying the write.
+
+ Typically this is neither configurable nor probeable, and depends on the path
+ taken through the memory system (i.e. it is a property of the combination of
+ MSI controller and device rather than a property of either in isolation).
+
+
+MSI controllers:
+================
+
+An MSI controller signals interrupts to a CPU when a write is made to an MMIO
+address by some master. An MSI controller may feature a number of doorbells.
+
+Required properties:
+--------------------
+
+- msi-controller: Identifies the node as an MSI controller.
+
+Optional properties:
+--------------------
+
+- #msi-cells: The number of cells in an msi-specifier, required if not zero.
+
+ Typically this will encode information related to sideband data, and will
+ not encode doorbells or payloads as these can be configured dynamically.
+
+ The meaning of the msi-specifier is defined by the device tree binding of
+ the specific MSI controller.
+
+
+MSI clients
+===========
+
+MSI clients are devices which generate MSIs. For each MSI they wish to
+generate, the doorbell and payload may be configured, though sideband
+information may not be configurable.
+
+Required properties:
+--------------------
+
+- msi-parent: A list of phandle + msi-specifier pairs, one for each MSI
+ controller which the device is capable of using.
+
+ This property is unordered, and MSIs may be allocated from any combination of
+ MSI controllers listed in the msi-parent property.
+
+ If a device has restrictions on the allocation of MSIs, these restrictions
+ must be described with additional properties.
+
+ When #msi-cells is non-zero, busses with an msi-parent will require
+ additional properties to describe the relationship between devices on the bus
+ and the set of MSIs they can potentially generate.
+
+
+Example
+=======
+
+/ {
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ msi_a: msi-controller@a {
+ reg = <0xa 0xf00>;

+ msi-controller;
+ /* No sideband data, so #msi-cells omitted */
+ };
+
+ msi_b: msi-controller@b {
+ reg = <0xb 0xf00>;
+ compatible = "vendor-b,another-controller";
+ msi-controller;
+ /* Each device has some unique ID */
+ #msi-cells = <1>;
+ };
+
+ msi_c: msi-controller@c {
+ reg = <0xb 0xf00>;
+ compatible = "vendor-b,another-controller";

+STMicroelectronics STi c8sectpfe binding
+============================================
+
+This document describes the c8sectpfe device bindings that is used to get transport
+stream data into the SoC on the TS pins, and into DDR for further processing.
+
+It is typically used in conjunction with one or more demodulator and tuner devices
+which converts from the RF to digital domain. Demodulators and tuners are usually
+located on an external DVB frontend card connected to SoC TS input pins.
+
+Currently 7 TS input (tsin) channels are supported on the stih407 family SoC.
+
+Required properties (controller (parent) node):
+- compatible : Should be "stih407-c8sectpfe"
+
+- reg : Address and length of register sets for each device in
+ "reg-names"
+
+- reg-names : The names of the register addresses corresponding to the
+ registers filled in "reg":
+ - c8sectpfe: c8sectpfe registers
+ - c8sectpfe-ram: c8sectpfe internal sram
+
+- clocks : phandle list of c8sectpfe clocks
+- clock-names : should be "c8sectpfe"
+See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+- pinctrl-names : a pinctrl state named tsin%d-serial or tsin%d-parallel (where %d is tsin-num)
+ must be defined for each tsin child node.
+- pinctrl-0 : phandle referencing pin configuration for this tsin configuration
+See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt
+
+
+Required properties (tsin (child) node):
+
+- tsin-num : tsin id of the InputBlock (must be between 0 to 6)
+- i2c-bus : phandle to the I2C bus DT node which the demodulators & tuners on this tsin channel are connected.
+- rst-gpio : reset gpio for this tsin channel.
+
+Optional properties (tsin (child) node):
+
+- invert-ts-clk : Bool property to control sense of ts input clock (data stored on falling edge of clk).
+- serial-not-parallel : Bool property to configure input bus width (serial on ts_data<7>).
+- async-not-sync : Bool property to control if data is received in asynchronous mode
+ (all bits/bytes with ts_valid or ts_packet asserted are valid).
+
+- dvb-card : Describes the NIM card connected to this tsin channel.
+
+Example:
+

+* NXP SPI Flash Interface (SPIFI)
+
+NXP SPIFI is a specialized SPI interface for serial Flash devices.
+It supports one Flash device with 1-, 2- and 4-bits width in SPI
+mode 0 or 3. The controller operates in either command or memory
+mode. In memory mode the Flash is accessible from the CPU as
+normal memory.
+
+Required properties:
+ - compatible : Should be "nxp,lpc1773-spifi"
+ - reg : the first contains the register location and length,
+ the second contains the memory mapping address and length
+ - reg-names: Should contain the reg names "spifi" and "flash"
+ - interrupts : Should contain the interrupt for the device
+ - clocks : The clocks needed by the SPIFI controller
+ - clock-names : Should contain the clock names "spifi" and "reg"
+
+Optional properties:
+ - resets : phandle + reset specifier
+
+The SPI Flash must be a child of the SPIFI node and must have a
+compatible property as specified in bindings/mtd/jedec,spi-nor.txt
+
+Optionally it can also contain the following properties.
+ - spi-cpol : Controller only supports mode 0 and 3 so either
+ both spi-cpol and spi-cpha should be present or
+ none of them
+ - spi-cpha : See above
+ - spi-rx-bus-width : Used to select how many pins that are used
+ for input on the controller
+
+See bindings/spi/spi-bus.txt for more information.

+Generic OPP (Operating Performance Points) Bindings
+----------------------------------------------------
+
+Devices work at voltage-current-frequency combinations and some implementations
+have the liberty of choosing these. These combinations are called Operating
+Performance Points aka OPPs. This document defines bindings for these OPPs
+applicable across wide range of devices. For illustration purpose, this document
+uses CPU as a device.
+
+This document contain multiple versions of OPP binding and only one of them
+should be used per device.
+
+Binding 1: operating-points
+============================
+
+This binding only supports voltage-frequency pairs.
+
+Properties:
+- operating-points: An array of 2-tuples items, and each item consists
+ of frequency and voltage like <freq-kHz vol-uV>.
+ freq: clock frequency in kHz
+ vol: voltage in microvolt
+
+Examples:
+
+cpu@0 {
+ compatible = "arm,cortex-a9";
+ reg = <0>;
+ next-level-cache = <&L2>;
+ operating-points = <
+ /* kHz uV */
+ 792000 1100000
+ 396000 950000
+ 198000 850000
+ >;
+};
+
+
+Binding 2: operating-points-v2
+============================
+
+* Property: operating-points-v2
+
+Devices supporting OPPs must set their "operating-points-v2" property with
+phandle to a OPP table in their DT node. The OPP core will use this phandle to
+find the operating points for the device.
+
+Devices may want to choose OPP tables at runtime and so can provide a list of
+phandles here. But only *one* of them should be chosen at runtime. This must be
+accompanied by a corresponding "operating-points-names" property, to uniquely
+identify the OPP tables.
+
+If required, this can be extended for SoC vendor specfic bindings. Such bindings
+should be documented as Documentation/devicetree/bindings/power/<vendor>-opp.txt
+and should have a compatible description like: "operating-points-v2-<vendor>".
+
+Optional properties:
+- operating-points-names: Names of OPP tables (required if multiple OPP
+ tables are present), to uniquely identify them. The same list must be present
+ for all the CPUs which are sharing clock/voltage rails and hence the OPP
+ tables.
+
+* OPP Table Node
+
+This describes the OPPs belonging to a device. This node can have following
+properties:
+
+Required properties:
+- compatible: Allow OPPs to express their compatibility. It should be:
+ "operating-points-v2".
+
+- OPP nodes: One or more OPP nodes describing voltage-current-frequency
+ combinations. Their name isn't significant but their phandle can be used to
+ reference an OPP.
+
+Optional properties:
+- opp-shared: Indicates that device nodes using this OPP Table Node's phandle
+ switch their DVFS state together, i.e. they share clock/voltage/current lines.
+ Missing property means devices have independent clock/voltage/current lines,
+ but they share OPP tables.
+
+- status: Marks the OPP table enabled/disabled.
+
+
+* OPP Node
+
+This defines voltage-current-frequency combinations along with other related
+properties.
+
+Required properties:
+- opp-hz: Frequency in Hz, expressed as a 64-bit big-endian integer.
+
+Optional properties:
+- opp-microvolt: voltage in micro Volts.
+
+ A single regulator's voltage is specified with an array of size one or three.
+ Single entry is for target voltage and three entries are for <target min max>
+ voltages.
+
+ Entries for multiple regulators must be present in the same order as
+ regulators are specified in device's DT node.
+
+- opp-microamp: The maximum current drawn by the device in microamperes
+ considering system specific parameters (such as transients, process, aging,
+ maximum operating temperature range etc.) as necessary. This may be used to
+ set the most efficient regulator operating mode.
+
+ Should only be set if opp-microvolt is set for the OPP.
+
+ Entries for multiple regulators must be present in the same order as
+ regulators are specified in device's DT node. If this property isn't required
+ for few regulators, then this should be marked as zero for them. If it isn't
+ required for any regulator, then this property need not be present.
+
+- clock-latency-ns: Specifies the maximum possible transition latency (in
+ nanoseconds) for switching to this OPP from any other OPP.
+
+- turbo-mode: Marks the OPP to be used only for turbo modes. Turbo mode is
+ available on some platforms, where the device can run over its operating
+ frequency for a short duration of time limited by the device's power, current
+ and thermal limits.
+
+- opp-suspend: Marks the OPP to be used during device suspend. Only one OPP in
+ the table should have this.
+
+- status: Marks the node enabled/disabled.
+
+Example 1: Single cluster Dual-core ARM cortex A9, switch DVFS states together.

+Conexant Digicolor CX92755 General Purpose Pin Mapping
+
+This document describes the device tree binding of the pin mapping hardware
+modules in the Conexant Digicolor CX92755 SoCs. The CX92755 in one of the
+Digicolor series of SoCs.
+
+=== Pin Controller Node ===
+
+Required Properties:
+
+- compatible: Must be "cnxt,cx92755-pinctrl"
+- reg: Base address of the General Purpose Pin Mapping register block and the
+ size of the block.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells: Must be <2>. The first cell is the pin number and the
+ second cell is used to specify flags. See include/dt-bindings/gpio/gpio.h
+ for possible values.
+
+For example, the following is the bare minimum node:
+
+ pinctrl: pinctrl@f0000e20 {
+ compatible = "cnxt,cx92755-pinctrl";
+ reg = <0xf0000e20 0x100>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+
+As a pin controller device, in addition to the required properties, this node
+should also contain the pin configuration nodes that client devices reference,
+if any.
+
+For a general description of GPIO bindings, please refer to ../gpio/gpio.txt.
+
+=== Pin Configuration Node ===
+
+Each pin configuration node is a sub-node of the pin controller node and is a
+container of an arbitrary number of subnodes, called pin group nodes in this
+document.
+
+Please refer to the pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the definition of a
+"pin configuration node".
+
+=== Pin Group Node ===
+
+A pin group node specifies the desired pin mux for an arbitrary number of
+pins. The name of the pin group node is optional and not used.
+
+A pin group node only affects the properties specified in the node, and has no
+effect on any properties that are omitted.
+
+The pin group node accepts a subset of the generic pin config properties. For
+details generic pin config properties, please refer to pinctrl-bindings.txt
+and <include/linux/pinctrl/pinconfig-generic.h>.
+
+Required Pin Group Node Properties:
+
+- pins: Multiple strings. Specifies the name(s) of one or more pins to be
+ configured by this node. The format of a pin name string is "GP_xy", where x
+ is an uppercase character from 'A' to 'R', and y is a digit from 0 to 7.
+- function: String. Specifies the pin mux selection. Values must be one of:
+ "gpio", "client_a", "client_b", "client_c"
+
+Example:
+ pinctrl: pinctrl@f0000e20 {
+ compatible = "cnxt,cx92755-pinctrl";
+ reg = <0xf0000e20 0x100>;
+
+ uart0_default: uart0_active {
+ data_signals {
+ pins = "GP_O0", "GP_O1";
+ function = "client_b";
+ };
+ };
+ };
+
+ uart0: uart@f0000740 {
+ compatible = "cnxt,cx92755-usart";
+ ...
+ pinctrl-0 = <&uart0_default>;
+ pinctrl-names = "default";
+ };
+
+In the example above, a single pin group configuration node defines the
+"client select" for the Rx and Tx signals of uart0. The uart0 node references
+that pin configuration node using the &uart0_default phandle.

-Generic OPP (Operating Performance Points) Bindings
-----------------------------------------------------
-
-Devices work at voltage-current-frequency combinations and some implementations
-have the liberty of choosing these. These combinations are called Operating
-Performance Points aka OPPs. This document defines bindings for these OPPs
-applicable across wide range of devices. For illustration purpose, this document
-uses CPU as a device.
-
-This document contain multiple versions of OPP binding and only one of them
-should be used per device.
-
-Binding 1: operating-points
-============================
-
-This binding only supports voltage-frequency pairs.
-
-Properties:
-- operating-points: An array of 2-tuples items, and each item consists
- of frequency and voltage like <freq-kHz vol-uV>.
- freq: clock frequency in kHz
- vol: voltage in microvolt
-
-Examples:
-
-cpu@0 {
- compatible = "arm,cortex-a9";
- reg = <0>;
- next-level-cache = <&L2>;
- operating-points = <
- /* kHz uV */
- 792000 1100000
- 396000 950000
- 198000 850000
- >;
-};
-
-
-Binding 2: operating-points-v2
-============================
-
-* Property: operating-points-v2
-
-Devices supporting OPPs must set their "operating-points-v2" property with
-phandle to a OPP table in their DT node. The OPP core will use this phandle to
-find the operating points for the device.
-
-Devices may want to choose OPP tables at runtime and so can provide a list of
-phandles here. But only *one* of them should be chosen at runtime. This must be
-accompanied by a corresponding "operating-points-names" property, to uniquely
-identify the OPP tables.
-
-If required, this can be extended for SoC vendor specfic bindings. Such bindings
-should be documented as Documentation/devicetree/bindings/power/<vendor>-opp.txt
-and should have a compatible description like: "operating-points-v2-<vendor>".
-
-Optional properties:
-- operating-points-names: Names of OPP tables (required if multiple OPP
- tables are present), to uniquely identify them. The same list must be present
- for all the CPUs which are sharing clock/voltage rails and hence the OPP
- tables.
-
-* OPP Table Node
-
-This describes the OPPs belonging to a device. This node can have following
-properties:
-
-Required properties:
-- compatible: Allow OPPs to express their compatibility. It should be:
- "operating-points-v2".
-
-- OPP nodes: One or more OPP nodes describing voltage-current-frequency
- combinations. Their name isn't significant but their phandle can be used to
- reference an OPP.
-
-Optional properties:
-- opp-shared: Indicates that device nodes using this OPP Table Node's phandle
- switch their DVFS state together, i.e. they share clock/voltage/current lines.
- Missing property means devices have independent clock/voltage/current lines,
- but they share OPP tables.
-
-- status: Marks the OPP table enabled/disabled.
-
-
-* OPP Node
-
-This defines voltage-current-frequency combinations along with other related
-properties.
-
-Required properties:
-- opp-hz: Frequency in Hz
-
-Optional properties:
-- opp-microvolt: voltage in micro Volts.
-
- A single regulator's voltage is specified with an array of size one or three.
- Single entry is for target voltage and three entries are for <target min max>
- voltages.
-
- Entries for multiple regulators must be present in the same order as
- regulators are specified in device's DT node.
-
-- opp-microamp: The maximum current drawn by the device in microamperes
- considering system specific parameters (such as transients, process, aging,
- maximum operating temperature range etc.) as necessary. This may be used to
- set the most efficient regulator operating mode.
-
- Should only be set if opp-microvolt is set for the OPP.
-
- Entries for multiple regulators must be present in the same order as
- regulators are specified in device's DT node. If this property isn't required
- for few regulators, then this should be marked as zero for them. If it isn't
- required for any regulator, then this property need not be present.
-
-- clock-latency-ns: Specifies the maximum possible transition latency (in
- nanoseconds) for switching to this OPP from any other OPP.
-
-- turbo-mode: Marks the OPP to be used only for turbo modes. Turbo mode is
- available on some platforms, where the device can run over its operating
- frequency for a short duration of time limited by the device's power, current
- and thermal limits.
-
-- opp-suspend: Marks the OPP to be used during device suspend. Only one OPP in
- the table should have this.
-
-- status: Marks the node enabled/disabled.

+Binding for Maxim MAX77686 regulators
+
+This is a part of the device tree bindings of MAX77686 multi-function device.
+More information can be found in ../mfd/max77686.txt file.
+
+The MAX77686 PMIC has 9 high-efficiency Buck and 26 Low-DropOut (LDO)
+regulators that can be controlled over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Optional node:
+- voltage-regulators : The regulators of max77686 have to be instantiated
+ under subnode named "voltage-regulators" using the following format.
+
+ regulator_name {
+ regulator-compatible = LDOn/BUCKn
+ standard regulator constraints....
+ };
+ refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+ The regulator node's name should be initialized with a string
+to get matched with their hardware counterparts as follow:
+
+ -LDOn : for LDOs, where n can lie in range 1 to 26.
+ example: LDO1, LDO2, LDO26.
+ -BUCKn : for BUCKs, where n can lie in range 1 to 9.
+ example: BUCK1, BUCK5, BUCK9.
+
+ Regulators which can be turned off during system suspend:
+ -LDOn : 2, 6-8, 10-12, 14-16,
+ -BUCKn : 1-4.
+ Use standard regulator bindings for it ('regulator-off-in-suspend').
+
+ LDO20, LDO21, LDO22, BUCK8 and BUCK9 can be configured to GPIO enable
+ control. To turn this feature on this property must be added to the regulator
+ sub-node:
+ - maxim,ena-gpios : one GPIO specifier enable control (the gpio

+ Intermediary duty-cycle values which would normally
+ allow finer grained voltage selection are ignored and
+ rendered useless. Although more control is given to
+ the user if the assumptions made in continuous-voltage
+ mode do not reign true.
+
+Continuous Voltage: This mode uses the regulator's maximum and minimum
+ supplied voltages specified in the
+ regulator-{min,max}-microvolt properties to calculate
+ appropriate duty-cycle values. This allows for a much
+ more fine grained solution when compared with
+ voltage-table mode above. This solution does make an
+ assumption that a %50 duty-cycle value will cause the
+ regulator voltage to run at half way between the
+ supplied max_uV and min_uV values.
Required properties:
-- compatible: Should be "pwm-regulator"
-- pwms: OF device-tree PWM specification (see PWM binding pwm.txt)
-- voltage-table: voltage and duty table, include 2 members in each set of
- brackets, first one is voltage(unit: uv), the next is duty(unit: percent)
+--------------------
+- compatible: Should be "pwm-regulator"
-Any property defined as part of the core regulator binding defined in
-regulator.txt can also be used.
+- pwms: PWM specification (See: ../pwm/pwm.txt)
-Example:
+Only required for Voltage Table Mode:
+- voltage-table: Voltage and Duty-Cycle table consisting of 2 cells
+ First cell is voltage in microvolts (uV)
+ Second cell is duty-cycle in percent (%)
+
+NB: To be clear, if voltage-table is provided, then the device will be used
+in Voltage Table Mode. If no voltage-table is provided, then the device will
+be used in Continuous Voltage Mode.
+
+Any property defined as part of the core regulator binding can also be used.

+
+Continuous Voltage Example:
pwm_regulator {

+MediaTek SCPSYS
+===============
+
+The System Control Processor System (SCPSYS) has several power management
+related tasks in the system. The tasks include thermal measurement, dynamic
+voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control.
+The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power
+domain control.
+
+The driver implements the Generic PM domain bindings described in
+power/power_domain.txt. It provides the power domains defined in
+include/dt-bindings/power/mt8173-power.h.
+
+Required properties:
+- compatible: Must be "mediatek,mt8173-scpsys"
+- #power-domain-cells: Must be 1
+- reg: Address range of the SCPSYS unit
+- infracfg: must contain a phandle to the infracfg controller
+- clock, clock-names: clocks according to the common clock binding.
+ The clocks needed "mm" and "mfg". These are the
+ clocks which hardware needs to be enabled before
+ enabling certain power domains.
+
+Example:
+
+ scpsys: scpsys@10006000 {
+ #power-domain-cells = <1>;
+ compatible = "mediatek,mt8173-scpsys";
+ reg = <0 0x10006000 0 0x1000>;
+ infracfg = <&infracfg>;
+ clocks = <&clk26m>,
+ <&topckgen CLK_TOP_MM_SEL>;
+ clock-names = "mfg", "mm";
+ };
+
+Example consumer:
+
+ afe: mt8173-afe-pcm@11220000 {
+ compatible = "mediatek,mt8173-afe-pcm";
+ power-domains = <&scpsys MT8173_POWER_DOMAIN_AUDIO>;

+Qualcomm Shared Memory Driver (SMD) binding
+
+This binding describes the Qualcomm Shared Memory Driver, a fifo based

+Qualcomm platforms.
+
+- compatible:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "qcom,smd"
+
+= EDGES
+
+Each subnode of the SMD node represents a remote subsystem or a remote
+processor of some sort - or in SMD language an "edge". The name of the edges
+are not important.
+The edge is described by the following properties:
+
+- interrupts:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: should specify the IRQ used by the remote processor to
+ signal this processor about communication related updates
+
+- qcom,ipc:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: three entries specifying the outgoing ipc bit used for
+ signaling the remote processor:
+ - phandle to a syscon node representing the apcs registers
+ - u32 representing offset to the register within the syscon
+ - u32 representing the ipc bit within the register
+
+- qcom,smd-edge:
+ Usage: required
+ Value type: <u32>
+ Definition: the identifier of the remote processor in the smd channel
+ allocation table
+
+- qcom,remote-pid:
+ Usage: optional
+ Value type: <u32>
+ Definition: the identifier for the remote processor as known by the rest
+ of the system.
+
+= SMD DEVICES
+
+In turn, subnodes of the "edges" represent devices tied to SMD channels on that
+"edge". The names of the devices are not important. The properties of these
+nodes are defined by the individual bindings for the SMD devices - but must
+contain the following property:
+
+- qcom,smd-channels:
+ Usage: required
+ Value type: <stringlist>
+ Definition: a list of channels tied to this device, used for matching
+ the device to channels
+
+= EXAMPLE
+
+The following example represents a smd node, with one edge representing the
+"rpm" subsystem. For the "rpm" subsystem we have a device tied to the
+"rpm_request" channel.

-Ext3 is the ext2 filesystem enhanced with journalling capabilities.
+Ext3 is the ext2 filesystem enhanced with journalling capabilities. The
+filesystem is a subset of ext4 filesystem so use ext4 driver for accessing
+ext3 filesystems.
-Options
-=======
-
-When mounting an ext3 filesystem, the following option are accepted:
-(*) == default
-
-ro Mount filesystem read only. Note that ext3 will replay
- the journal (and thus write to the partition) even when
- mounted "read only". Mount options "ro,noload" can be
- used to prevent writes to the filesystem.
-
-journal=update Update the ext3 file system's journal to the current
- format.
-
-journal=inum When a journal already exists, this option is ignored.
- Otherwise, it specifies the number of the inode which
- will represent the ext3 file system's journal file.
-
-journal_path=path
-journal_dev=devnum When the external journal device's major/minor numbers
- have changed, these options allow the user to specify
- the new journal location. The journal device is
- identified through either its new major/minor numbers
- encoded in devnum, or via a path to the device.
-
-norecovery Don't load the journal on mounting. Note that this forces
-noload mount of inconsistent filesystem, which can lead to
- various problems.
-
-data=journal All data are committed into the journal prior to being
- written into the main file system.
-
-data=ordered (*) All data are forced directly out to the main file
- system prior to its metadata being committed to the
- journal.
-
-data=writeback Data ordering is not preserved, data may be written
- into the main file system after its metadata has been
- committed to the journal.
-
-commit=nrsec (*) Ext3 can be told to sync all its data and metadata
- every 'nrsec' seconds. The default value is 5 seconds.
- This means that if you lose your power, you will lose
- as much as the latest 5 seconds of work (your
- filesystem will not be damaged though, thanks to the
- journaling). This default value (or any low value)
- will hurt performance, but it's good for data-safety.
- Setting it to 0 will have the same effect as leaving
- it at the default (5 seconds).
- Setting it to very large values will improve
- performance.
-
-barrier=<0|1(*)> This enables/disables the use of write barriers in
-barrier (*) the jbd code. barrier=0 disables, barrier=1 enables.
-nobarrier This also requires an IO stack which can support
- barriers, and if jbd gets an error on a barrier
- write, it will disable again with a warning.
- Write barriers enforce proper on-disk ordering
- of journal commits, making volatile disk write caches
- safe to use, at some performance penalty. If
- your disks are battery-backed in one way or another,
- disabling barriers may safely improve performance.
- The mount options "barrier" and "nobarrier" can
- also be used to enable or disable barriers, for
- consistency with other ext3 mount options.
-
-user_xattr Enables Extended User Attributes. Additionally, you
- need to have extended attribute support enabled in the
- kernel configuration (CONFIG_EXT3_FS_XATTR). See the
- attr(5) manual page and http://acl.bestbits.at/ to
- learn more about extended attributes.
-
-nouser_xattr Disables Extended User Attributes.
-
-acl Enables POSIX Access Control Lists support.
- Additionally, you need to have ACL support enabled in
- the kernel configuration (CONFIG_EXT3_FS_POSIX_ACL).
- See the acl(5) manual page and http://acl.bestbits.at/
- for more information.
-
-noacl This option disables POSIX Access Control List
- support.
-
-reservation
-
-noreservation
-
-bsddf (*) Make 'df' act like BSD.
-minixdf Make 'df' act like Minix.
-
-check=none Don't do extra checking of bitmaps on mount.
-nocheck
-
-debug Extra debugging information is sent to syslog.
-
-errors=remount-ro Remount the filesystem read-only on an error.
-errors=continue Keep going on a filesystem error.
-errors=panic Panic and halt the machine if an error occurs.
- (These mount options override the errors behavior
- specified in the superblock, which can be
- configured using tune2fs.)
-
-data_err=ignore(*) Just print an error message if an error occurs
- in a file data buffer in ordered mode.
-data_err=abort Abort the journal if an error occurs in a file
- data buffer in ordered mode.
-
-grpid Give objects the same group ID as their creator.
-bsdgroups
-
-nogrpid (*) New objects have the group ID of their creator.
-sysvgroups
-
-resgid=n The group ID which may use the reserved blocks.
-
-resuid=n The user ID which may use the reserved blocks.
-
-sb=n Use alternate superblock at this location.
-
-quota These options are ignored by the filesystem. They
-noquota are used only by quota tools to recognize volumes
-grpquota where quota should be turned on. See documentation
-usrquota in the quota-tools package for more details
- (http://sourceforge.net/projects/linuxquota).
-
-jqfmt=<quota type> These options tell filesystem details about quota
-usrjquota=<file> so that quota information can be properly updated
-grpjquota=<file> during journal replay. They replace the above
- quota options. See documentation in the quota-tools
- package for more details
- (http://sourceforge.net/projects/linuxquota).
-
-Specification
-=============
-Ext3 shares all disk implementation with the ext2 filesystem, and adds
-transactions capabilities to ext2. Journaling is done by the Journaling Block
-Device layer.
-
-Journaling Block Device layer
------------------------------
-The Journaling Block Device layer (JBD) isn't ext3 specific. It was designed
-to add journaling capabilities to a block device. The ext3 filesystem code
-will inform the JBD of modifications it is performing (called a transaction).
-The journal supports the transactions start and stop, and in case of a crash,
-the journal can replay the transactions to quickly put the partition back into
-a consistent state.
-
-Handles represent a single atomic update to a filesystem. JBD can handle an
-external journal on a block device.
-
-Data Mode
----------
-There are 3 different data modes:
-
-* writeback mode
-In data=writeback mode, ext3 does not journal data at all. This mode provides
-a similar level of journaling as that of XFS, JFS, and ReiserFS in its default
-mode - metadata journaling. A crash+recovery can cause incorrect data to
-appear in files which were written shortly before the crash. This mode will
-typically provide the best ext3 performance.
-
-* ordered mode
-In data=ordered mode, ext3 only officially journals metadata, but it logically
-groups metadata and data blocks into a single unit called a transaction. When
-it's time to write the new metadata out to disk, the associated data blocks
-are written first. In general, this mode performs slightly slower than
-writeback but significantly faster than journal mode.
-
-* journal mode
-data=journal mode provides full data and metadata journaling. All new data is
-written to the journal first, and then to its final location.
-In the event of a crash, the journal can be replayed, bringing both data and
-metadata into a consistent state. This mode is the slowest except when data
-needs to be read from and written to disk at the same time where it
-outperforms all other modes.
-
-Compatibility
--------------
-
-Ext2 partitions can be easily convert to ext3, with `tune2fs -j <dev>`.
-Ext3 is fully compatible with Ext2. Ext3 partitions can easily be mounted as
-Ext2.
-
-
-External Tools
-==============
-See manual pages to learn more.
-
-tune2fs: create a ext3 journal on a ext2 partition with the -j flag.
-mke2fs: create a ext3 partition with the -j flag.
-debugfs: ext2 and ext3 file system debugger.
-ext2online: online (mounted) ext2 and ext3 filesystem resizer

+The active-low property
+-----------------------
+
+As a driver 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.
+
+With this, all the gpiod_set_(array)_value_xxx() functions interpret the
+parameter "value" as "active" ("1") or "inactive" ("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 "active" ("1"), the physical line level
+will be driven low.
+
+To summarize:
+
+Function (example) active-low proporty 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, 1); default (active-high) high
+gpiod_set_value(desc, 0); active-low high
+gpiod_set_value(desc, 1); active-low low

+Please note again that the set_raw/get_raw functions should be avoided as much
+as possible, especially by drivers which should not care about the actual
+physical line level and worry about the logical value instead.

+Subsystem drivers using GPIO
+============================
+
+Note that standard kernel drivers exist for common GPIO tasks and will provide
+the right in-kernel and userspace APIs/ABIs for the job, and that these
+drivers can quite easily interconnect with other kernel subsystems using
+hardware descriptions such as device tree or ACPI:
+
+- leds-gpio: drivers/leds/leds-gpio.c will handle LEDs connected to GPIO
+ lines, giving you the LED sysfs interface
+
+- ledtrig-gpio: drivers/leds/trigger/ledtrig-gpio.c will provide a LED trigger,
+ i.e. a LED will turn on/off in response to a GPIO line going high or low
+ (and that LED may in turn use the leds-gpio as per above).
+
+- gpio-keys: drivers/input/keyboard/gpio_keys.c is used when your GPIO line
+ can generate interrupts in response to a key press. Also supports debounce.
+
+- gpio-keys-polled: drivers/input/keyboard/gpio_keys_polled.c is used when your
+ GPIO line cannot generate interrupts, so it needs to be periodically polled
+ by a timer.
+
+- gpio_mouse: drivers/input/mouse/gpio_mouse.c is used to provide a mouse with
+ up to three buttons by simply using GPIOs and no mouse port. You can cut the
+ mouse cable and connect the wires to GPIO lines or solder a mouse connector
+ to the lines for a more permanent solution of this type.
+
+- gpio-beeper: drivers/input/misc/gpio-beeper.c is used to provide a beep from
+ an external speaker connected to a GPIO line.
+
+- gpio-tilt-polled: drivers/input/misc/gpio_tilt_polled.c provides tilt
+ detection switches using GPIO, which is useful for your homebrewn pinball
+ machine if for nothing else. It can detect different tilt angles of the
+ monitored object.
+
+- extcon-gpio: drivers/extcon/extcon-gpio.c is used when you need to read an
+ external connector status, such as a headset line for an audio driver or an
+ HDMI connector. It will provide a better userspace sysfs interface than GPIO.
+
+- restart-gpio: drivers/power/gpio-restart.c is used to restart/reboot the
+ system by pulling a GPIO line and will register a restart handler so
+ userspace can issue the right system call to restart the system.
+
+- poweroff-gpio: drivers/power/gpio-poweroff.c is used to power the system down
+ by pulling a GPIO line and will register a pm_power_off() callback so that
+ userspace can issue the right system call to power down the system.
+
+- gpio-gate-clock: drivers/clk/clk-gpio-gate.c is used to control a gated clock
+ (off/on) that uses a GPIO, and integrated with the clock subsystem.
+
+- i2c-gpio: drivers/i2c/busses/i2c-gpio.c is used to drive an I2C bus
+ (two wires, SDA and SCL lines) by hammering (bitbang) two GPIO lines. It will
+ appear as any other I2C bus to the system and makes it possible to connect
+ drivers for the I2C devices on the bus like any other I2C bus driver.
+
+- spi_gpio: drivers/spi/spi-gpio.c is used to drive an SPI bus (variable number
+ of wires, atleast SCK and optionally MISO, MOSI and chip select lines) using
+ GPIO hammering (bitbang). It will appear as any other SPI bus on the system
+ and makes it possible to connect drivers for SPI devices on the bus like
+ any other SPI bus driver. For example any MMC/SD card can then be connected
+ to this SPI by using the mmc_spi host from the MMC/SD card subsystem.
+
+- w1-gpio: drivers/w1/masters/w1-gpio.c is used to drive a one-wire bus using
+ a GPIO line, integrating with the W1 subsystem and handling devices on
+ the bus like any other W1 device.
+
+- gpio-fan: drivers/hwmon/gpio-fan.c is used to control a fan for cooling the
+ system, connected to a GPIO line (and optionally a GPIO alarm line),
+ presenting all the right in-kernel and sysfs interfaces to make your system
+ not overheat.
+
+- gpio-regulator: drivers/regulator/gpio-regulator.c is used to control a
+ regulator providing a certain voltage by pulling a GPIO line, integrating
+ with the regulator subsystem and giving you all the right interfaces.
+
+- gpio-wdt: drivers/watchdog/gpio_wdt.c is used to provide a watchdog timer
+ that will periodically "ping" a hardware connected to a GPIO line by toggling
+ it from 1-to-0-to-1. If that hardware does not recieve its "ping"
+ periodically, it will reset the system.
+
+- gpio-nand: drivers/mtd/nand/gpio.c is used to connect a NAND flash chip to
+ a set of simple GPIO lines: RDY, NCE, ALE, CLE, NWP. It interacts with the
+ NAND flash MTD subsystem and provides chip access and partition parsing like
+ any other NAND driving hardware.
+
+Apart from this there are special GPIO drivers in subsystems like MMC/SD to
+read card detect and write protect GPIO lines, and in the TTY serial subsystem
+to emulate MCTRL (modem control) signals CTS/RTS by using two GPIO lines. The
+MTD NOR flash has add-ons for extra GPIO lines too, though the address bus is
+usually connected directly to the flash.
+
+Use those instead of talking directly to the GPIOs using sysfs; they integrate
+with kernel frameworks better than your userspace code could. Needless to say,
+just using the apropriate kernel drivers will simplify and speed up your
+embedded hacking in particular by providing ready-made components.

I2C slave backends behave like standard I2C clients. So, you can instantiate

+is that i2c slave backends have their own address space. So, you have to add

- # echo slave-24c02 0x64 > /sys/bus/i2c/devices/i2c-1/new_device
+ # echo slave-24c02 0x1064 > /sys/bus/i2c/devices/i2c-1/new_device
Each backend should come with separate documentation to describe its specific
behaviour and setup.

+1 Introduction
+===============
+ This document describes the architecture and implementation of the MEN
+ Chameleon Bus (called MCB throughout this document).
+
+1.1 Scope of this Document
+---------------------------
+ This document is intended to be a short overview of the current
+ implementation and does by no means describe the complete possibilities of MCB
+ based devices.
+
+1.2 Limitations of the current implementation
+----------------------------------------------
+ The current implementation is limited to PCI and PCIe based carrier devices
+ that only use a single memory resource and share the PCI legacy IRQ. Not
+ implemented are:
+ - Multi-resource MCB devices like the VME Controller or M-Module carrier.
+ - MCB devices that need another MCB device, like SRAM for a DMA Controller's
+ buffer descriptors or a video controller's video memory.
+ - A per-carrier IRQ domain for carrier devices that have one (or more) IRQs
+ per MCB device like PCIe based carriers with MSI or MSI-X support.
+
+2 Architecture
+===============
+ MCB is divided into 3 functional blocks:
+ - The MEN Chameleon Bus itself,
+ - drivers for MCB Carrier Devices and
+ - the parser for the Chameleon table.
+
+2.1 MEN Chameleon Bus
+----------------------
+ The MEN Chameleon Bus is an artificial bus system that attaches to a so
+ called Chameleon FPGA device found on some hardware produced my MEN Mikro
+ Elektronik GmbH. These devices are multi-function devices implemented in a
+ single FPGA and usually attached via some sort of PCI or PCIe link. Each
+ FPGA contains a header section describing the content of the FPGA. The
+ header lists the device id, PCI BAR, offset from the beginning of the PCI
+ BAR, size in the FPGA, interrupt number and some other properties currently
+ not handled by the MCB implementation.
+
+2.2 Carrier Devices
+--------------------
+ A carrier device is just an abstraction for the real world physical bus the
+ Chameleon FPGA is attached to. Some IP Core drivers may need to interact with
+ properties of the carrier device (like querying the IRQ number of a PCI
+ device). To provide abstraction from the real hardware bus, an MCB carrier
+ device provides callback methods to translate the driver's MCB function calls
+ to hardware related function calls. For example a carrier device may
+ implement the get_irq() method which can be translated into a hardware bus
+ query for the IRQ number the device should use.
+
+2.3 Parser
+-----------
+ The parser reads the first 512 bytes of a Chameleon device and parses the
+ Chameleon table. Currently the parser only supports the Chameleon v2 variant
+ of the Chameleon table but can easily be adopted to support an older or
+ possible future variant. While parsing the table's entries new MCB devices
+ are allocated and their resources are assigned according to the resource
+ assignment in the Chameleon table. After resource assignment is finished, the
+ MCB devices are registered at the MCB and thus at the driver core of the
+ Linux kernel.
+
+3 Resource handling
+====================
+ The current implementation assigns exactly one memory and one IRQ resource
+ per MCB device. But this is likely going to change in the future.
+
+3.1 Memory Resources
+---------------------
+ Each MCB device has exactly one memory resource, which can be requested from
+ the MCB bus. This memory resource is the physical address of the MCB device
+ inside the carrier and is intended to be passed to ioremap() and friends. It
+ is already requested from the kernel by calling request_mem_region().
+
+3.2 IRQs
+---------
+ Each MCB device has exactly one IRQ resource, which can be requested from the
+ MCB bus. If a carrier device driver implements the ->get_irq() callback
+ method, the IRQ number assigned by the carrier device will be returned,
+ otherwise the IRQ number inside the Chameleon table will be returned. This
+ number is suitable to be passed to request_irq().
+
+4 Writing an MCB driver
+=======================
+
+4.1 The driver structure
+-------------------------
+ Each MCB driver has a structure to identify the device driver as well as
+ device ids which identify the IP Core inside the FPGA. The driver structure
+ also contains callback methods which get executed on driver probe and
+ removal from the system.
+
+
+ static const struct mcb_device_id foo_ids[] = {
+ { .device = 0x123 },

+
+4.2 Probing and attaching
+--------------------------
+ When a driver is loaded and the MCB devices it services are found, the MCB
+ core will call the driver's probe callback method. When the driver is removed
+ from the system, the MCB core will call the driver's remove callback method.
+
+
+ static init foo_probe(struct mcb_device *mdev, const struct mcb_device_id *id);
+ static void foo_remove(struct mcb_device *mdev);
+
+4.3 Initializing the driver
+----------------------------
+ When the kernel is booted or your foo driver module is inserted, you have to
+ perform driver initialization. Usually it is enough to register your driver
+ module at the MCB core.
+
+
+ static int __init foo_init(void)
+ {
+ return mcb_register_driver(&foo_driver);
+ }
+ module_init(foo_init);
+
+ static void __exit foo_exit(void)
+ {
+ mcb_unregister_driver(&foo_driver);
+ }
+ module_exit(foo_exit);
+
+ The module_mcb_driver() macro can be used to reduce the above code.
+
+
+ module_mcb_driver(foo_driver);

+Broadcom Starfighter 2 Ethernet switch driver
+=============================================
+
+Broadcom's Starfighter 2 Ethernet switch hardware block is commonly found and
+deployed in the following products:
+
+- xDSL gateways such as BCM63138
+- streaming/multimedia Set Top Box such as BCM7445
+- Cable Modem/residential gateways such as BCM7145/BCM3390
+
+The switch is typically deployed in a configuration involving between 5 to 13
+ports, offering a range of built-in and customizable interfaces:
+
+- single integrated Gigabit PHY
+- quad integrated Gigabit PHY
+- quad external Gigabit PHY w/ MDIO multiplexer
+- integrated MoCA PHY
+- several external MII/RevMII/GMII/RGMII interfaces
+
+The switch also supports specific congestion control features which allow MoCA
+fail-over not to lose packets during a MoCA role re-election, as well as out of
+band back-pressure to the host CPU network interface when downstream interfaces
+are connected at a lower speed.
+
+The switch hardware block is typically interfaced using MMIO accesses and
+contains a bunch of sub-blocks/registers:
+
+* SWITCH_CORE: common switch registers
+* SWITCH_REG: external interfaces switch register
+* SWITCH_MDIO: external MDIO bus controller (there is another one in SWITCH_CORE,
+ which is used for indirect PHY accesses)
+* SWITCH_INDIR_RW: 64-bits wide register helper block
+* SWITCH_INTRL2_0/1: Level-2 interrupt controllers
+* SWITCH_ACB: Admission control block
+* SWITCH_FCB: Fail-over control block
+
+Implementation details
+======================
+
+The driver is located in drivers/net/dsa/bcm_sf2.c and is implemented as a DSA
+driver; see Documentation/networking/dsa/dsa.txt for details on the subsytem
+and what it provides.
+
+The SF2 switch is configured to enable a Broadcom specific 4-bytes switch tag
+which gets inserted by the switch for every packet forwarded to the CPU
+interface, conversely, the CPU network interface should insert a similar tag for
+packets entering the CPU port. The tag format is described in
+net/dsa/tag_brcm.c.
+
+Overall, the SF2 driver is a fairly regular DSA driver; there are a few
+specifics covered below.
+
+Device Tree probing
+-------------------
+
+The DSA platform device driver is probed using a specific compatible string
+provided in net/dsa/dsa.c. The reason for that is because the DSA subsystem gets
+registered as a platform device driver currently. DSA will provide the needed
+device_node pointers which are then accessible by the switch driver setup
+function to setup resources such as register ranges and interrupts. This
+currently works very well because none of the of_* functions utilized by the
+driver require a struct device to be bound to a struct device_node, but things
+may change in the future.
+
+MDIO indirect accesses
+----------------------
+
+Due to a limitation in how Broadcom switches have been designed, external
+Broadcom switches connected to a SF2 require the use of the DSA slave MDIO bus
+in order to properly configure them. By default, the SF2 pseudo-PHY address, and
+an external switch pseudo-PHY address will both be snooping for incoming MDIO
+transactions, since they are at the same address (30), resulting in some kind of
+"double" programming. Using DSA, and setting ds->phys_mii_mask accordingly, we
+selectively divert reads and writes towards external Broadcom switches
+pseudo-PHY addresses. Newer revisions of the SF2 hardware have introduced a
+configurable pseudo-PHY address which circumvents the initial design limitation.
+
+Multimedia over CoAxial (MoCA) interfaces
+-----------------------------------------
+
+MoCA interfaces are fairly specific and require the use of a firmware blob which
+gets loaded onto the MoCA processor(s) for packet processing. The switch
+hardware contains logic which will assert/de-assert link states accordingly for
+the MoCA interface whenever the MoCA coaxial cable gets disconnected or the
+firmware gets reloaded. The SF2 driver relies on such events to properly set its
+MoCA interface carrier state and properly report this to the networking stack.
+
+The MoCA interfaces are supported using the PHY library's fixed PHY/emulated PHY
+device and the switch driver registers a fixed_link_update callback for such
+PHYs which reflects the link state obtained from the interrupt handler.
+
+
+Power Management
+----------------
+
+Whenever possible, the SF2 driver tries to minimize the overall switch power
+consumption by applying a combination of:
+
+- turning off internal buffers/memories
+- disabling packet processing logic
+- putting integrated PHYs in IDDQ/low-power
+- reducing the switch core clock based on the active port count
+- enabling and advertising EEE
+- turning off RGMII data processing logic when the link goes down
+
+Wake-on-LAN
+-----------
+
+Wake-on-LAN is currently implemented by utilizing the host processor Ethernet
+MAC controller wake-on logic. Whenever Wake-on-LAN is requested, an intersection
+between the user request and the supported host Ethernet interface WoL
+capabilities is done and the intersection result gets configured. During
+system-wide suspend/resume, only ports not participating in Wake-on-LAN are
+disabled.

+Distributed Switch Architecture
+===============================
+
+Introduction
+============
+
+This document describes the Distributed Switch Architecture (DSA) subsystem
+design principles, limitations, interactions with other subsystems, and how to
+develop drivers for this subsystem as well as a TODO for developers interested
+in joining the effort.
+
+Design principles
+=================
+
+The Distributed Switch Architecture is a subsystem which was primarily designed
+to support Marvell Ethernet switches (MV88E6xxx, a.k.a Linkstreet product line)
+using Linux, but has since evolved to support other vendors as well.
+
+The original philosophy behind this design was to be able to use unmodified
+Linux tools such as bridge, iproute2, ifconfig to work transparently whether
+they configured/queried a switch port network device or a regular network
+device.
+
+An Ethernet switch is typically comprised of multiple front-panel ports, and one
+or more CPU or management port. The DSA subsystem currently relies on the
+presence of a management port connected to an Ethernet controller capable of
+receiving Ethernet frames from the switch. This is a very common setup for all
+kinds of Ethernet switches found in Small Home and Office products: routers,
+gateways, or even top-of-the rack switches. This host Ethernet controller will
+be later referred to as "master" and "cpu" in DSA terminology and code.
+
+The D in DSA stands for Distributed, because the subsystem has been designed
+with the ability to configure and manage cascaded switches on top of each other
+using upstream and downstream Ethernet links between switches. These specific
+ports are referred to as "dsa" ports in DSA terminology and code. A collection
+of multiple switches connected to each other is called a "switch tree".
+
+For each front-panel port, DSA will create specialized network devices which are
+used as controlling and data-flowing endpoints for use by the Linux networking
+stack. These specialized network interfaces are referred to as "slave" network
+interfaces in DSA terminology and code.
+
+The ideal case for using DSA is when an Ethernet switch supports a "switch tag"
+which is a hardware feature making the switch insert a specific tag for each
+Ethernet frames it received to/from specific ports to help the management
+interface figure out:
+
+- what port is this frame coming from
+- what was the reason why this frame got forwarded
+- how to send CPU originated traffic to specific ports
+
+The subsystem does support switches not capable of inserting/stripping tags, but
+the features might be slightly limited in that case (traffic separation relies
+on Port-based VLAN IDs).
+
+Note that DSA does not currently create network interfaces for the "cpu" and
+"dsa" ports because:
+
+- the "cpu" port is the Ethernet switch facing side of the management
+ controller, and as such, would create a duplication of feature, since you
+ would get two interfaces for the same conduit: master netdev, and "cpu" netdev
+
+- the "dsa" port(s) are just conduits between two or more switches, and as such
+ cannot really be used as proper network interfaces either, only the
+ downstream, or the top-most upstream interface makes sense with that model
+
+Switch tagging protocols
+------------------------
+
+DSA currently supports 4 different tagging protocols, and a tag-less mode as
+well. The different protocols are implemented in:
+
+net/dsa/tag_trailer.c: Marvell's 4 trailer tag mode (legacy)
+net/dsa/tag_dsa.c: Marvell's original DSA tag
+net/dsa/tag_edsa.c: Marvell's enhanced DSA tag
+net/dsa/tag_brcm.c: Broadcom's 4 bytes tag
+
+The exact format of the tag protocol is vendor specific, but in general, they
+all contain something which:
+
+- identifies which port the Ethernet frame came from/should be sent to
+- provides a reason why this frame was forwarded to the management interface
+
+Master network devices
+----------------------
+
+Master network devices are regular, unmodified Linux network device drivers for
+the CPU/management Ethernet interface. Such a driver might occasionally need to
+know whether DSA is enabled (e.g.: to enable/disable specific offload features),
+but the DSA subsystem has been proven to work with industry standard drivers:
+e1000e, mv643xx_eth etc. without having to introduce modifications to these
+drivers. Such network devices are also often referred to as conduit network
+devices since they act as a pipe between the host processor and the hardware
+Ethernet switch.
+
+Networking stack hooks
+----------------------
+
+When a master netdev is used with DSA, a small hook is placed in in the
+networking stack is in order to have the DSA subsystem process the Ethernet
+switch specific tagging protocol. DSA accomplishes this by registering a
+specific (and fake) Ethernet type (later becoming skb->protocol) with the
+networking stack, this is also known as a ptype or packet_type. A typical
+Ethernet Frame receive sequence looks like this:
+
+Master network device (e.g.: e1000e):
+
+Receive interrupt fires:
+- receive function is invoked
+- basic packet processing is done: getting length, status etc.
+- packet is prepared to be processed by the Ethernet layer by calling
+ eth_type_trans
+
+net/ethernet/eth.c:
+
+eth_type_trans(skb, dev)
+ if (dev->dsa_ptr != NULL)
+ -> skb->protocol = ETH_P_XDSA
+
+drivers/net/ethernet/*:
+
+netif_receive_skb(skb)
+ -> iterate over registered packet_type
+ -> invoke handler for ETH_P_XDSA, calls dsa_switch_rcv()
+
+net/dsa/dsa.c:
+ -> dsa_switch_rcv()
+ -> invoke switch tag specific protocol handler in
+ net/dsa/tag_*.c
+
+net/dsa/tag_*.c:
+ -> inspect and strip switch tag protocol to determine originating port
+ -> locate per-port network device
+ -> invoke eth_type_trans() with the DSA slave network device
+ -> invoked netif_receive_skb()
+
+Past this point, the DSA slave network devices get delivered regular Ethernet
+frames that can be processed by the networking stack.
+
+Slave network devices
+---------------------
+
+Slave network devices created by DSA are stacked on top of their master network
+device, each of these network interfaces will be responsible for being a
+controlling and data-flowing end-point for each front-panel port of the switch.
+These interfaces are specialized in order to:
+
+- insert/remove the switch tag protocol (if it exists) when sending traffic
+ to/from specific switch ports
+- query the switch for ethtool operations: statistics, link state,
+ Wake-on-LAN, register dumps...
+- external/internal PHY management: link, auto-negotiation etc.
+
+These slave network devices have custom net_device_ops and ethtool_ops function
+pointers which allow DSA to introduce a level of layering between the networking
+stack/ethtool, and the switch driver implementation.
+
+Upon frame transmission from these slave network devices, DSA will look up which
+switch tagging protocol is currently registered with these network devices, and
+invoke a specific transmit routine which takes care of adding the relevant
+switch tag in the Ethernet frames.
+
+These frames are then queued for transmission using the master network device
+ndo_start_xmit() function, since they contain the appropriate switch tag, the
+Ethernet switch will be able to process these incoming frames from the
+management interface and delivers these frames to the physical switch port.
+
+Graphical representation
+------------------------
+
+Summarized, this is basically how DSA looks like from a network device
+perspective:
+
+
+ |---------------------------
+ | CPU network device (eth0)|
+ ----------------------------
+ | <tag added by switch |
+ | |
+ | |
+ | tag added by CPU> |
+ |--------------------------------------------|
+ | Switch driver |
+ |--------------------------------------------|
+ || || ||
+ |-------| |-------| |-------|
+ | sw0p0 | | sw0p1 | | sw0p2 |
+ |-------| |-------| |-------|
+
+Slave MDIO bus
+--------------
+
+In order to be able to read to/from a switch PHY built into it, DSA creates a
+slave MDIO bus which allows a specific switch driver to divert and intercept
+MDIO reads/writes towards specific PHY addresses. In most MDIO-connected
+switches, these functions would utilize direct or indirect PHY addressing mode
+to return standard MII registers from the switch builtin PHYs, allowing the PHY
+library and/or to return link status, link partner pages, auto-negotiation
+results etc..
+
+For Ethernet switches which have both external and internal MDIO busses, the
+slave MII bus can be utilized to mux/demux MDIO reads and writes towards either
+internal or external MDIO devices this switch might be connected to: internal
+PHYs, external PHYs, or even external switches.
+
+Data structures
+---------------
+
+DSA data structures are defined in include/net/dsa.h as well as
+net/dsa/dsa_priv.h.
+
+dsa_chip_data: platform data configuration for a given switch device, this
+structure describes a switch device's parent device, its address, as well as
+various properties of its ports: names/labels, and finally a routing table
+indication (when cascading switches)
+
+dsa_platform_data: platform device configuration data which can reference a
+collection of dsa_chip_data structure if multiples switches are cascaded, the
+master network device this switch tree is attached to needs to be referenced
+
+dsa_switch_tree: structure assigned to the master network device under
+"dsa_ptr", this structure references a dsa_platform_data structure as well as
+the tagging protocol supported by the switch tree, and which receive/transmit
+function hooks should be invoked, information about the directly attached switch
+is also provided: CPU port. Finally, a collection of dsa_switch are referenced
+to address individual switches in the tree.
+
+dsa_switch: structure describing a switch device in the tree, referencing a
+dsa_switch_tree as a backpointer, slave network devices, master network device,
+and a reference to the backing dsa_switch_driver
+
+dsa_switch_driver: structure referencing function pointers, see below for a full
+description.
+
+Design limitations
+==================
+
+DSA is a platform device driver
+-------------------------------
+
+DSA is implemented as a DSA platform device driver which is convenient because
+it will register the entire DSA switch tree attached to a master network device
+in one-shot, facilitating the device creation and simplifying the device driver
+model a bit, this comes however with a number of limitations:
+
+- building DSA and its switch drivers as modules is currently not working
+- the device driver parenting does not necessarily reflect the original
+ bus/device the switch can be created from
+- supporting non-MDIO and non-MMIO (platform) switches is not possible
+
+Limits on the number of devices and ports
+-----------------------------------------
+
+DSA currently limits the number of maximum switches within a tree to 4
+(DSA_MAX_SWITCHES), and the number of ports per switch to 12 (DSA_MAX_PORTS).
+These limits could be extended to support larger configurations would this need
+arise.
+
+Lack of CPU/DSA network devices
+-------------------------------
+
+DSA does not currently create slave network devices for the CPU or DSA ports, as
+described before. This might be an issue in the following cases:
+
+- inability to fetch switch CPU port statistics counters using ethtool, which
+ can make it harder to debug MDIO switch connected using xMII interfaces
+
+- inability to configure the CPU port link parameters based on the Ethernet
+ controller capabilities attached to it: http://patchwork.ozlabs.org/patch/509806/
+
+- inability to configure specific VLAN IDs / trunking VLANs between switches
+ when using a cascaded setup
+
+Common pitfalls using DSA setups
+--------------------------------
+
+Once a master network device is configured to use DSA (dev->dsa_ptr becomes
+non-NULL), and the switch behind it expects a tagging protocol, this network
+interface can only exclusively be used as a conduit interface. Sending packets
+directly through this interface (e.g.: opening a socket using this interface)
+will not make us go through the switch tagging protocol transmit function, so
+the Ethernet switch on the other end, expecting a tag will typically drop this
+frame.
+
+Slave network devices check that the master network device is UP before allowing
+you to administratively bring UP these slave network devices. A common
+configuration mistake is forgetting to bring UP the master network device first.
+
+Interactions with other subsystems
+==================================
+
+DSA currently leverages the following subsystems:
+
+- MDIO/PHY library: drivers/net/phy/phy.c, mdio_bus.c
+- Switchdev: net/switchdev/*
+- Device Tree for various of_* functions
+- HWMON: drivers/hwmon/*
+
+MDIO/PHY library
+----------------
+
+Slave network devices exposed by DSA may or may not be interfacing with PHY
+devices (struct phy_device as defined in include/linux/phy.h), but the DSA
+subsystem deals with all possible combinations:
+
+- internal PHY devices, built into the Ethernet switch hardware
+- external PHY devices, connected via an internal or external MDIO bus
+- internal PHY devices, connected via an internal MDIO bus
+- special, non-autonegotiated or non MDIO-managed PHY devices: SFPs, MoCA; a.k.a
+ fixed PHYs
+
+The PHY configuration is done by the dsa_slave_phy_setup() function and the
+logic basically looks like this:
+
+- if Device Tree is used, the PHY device is looked up using the standard
+ "phy-handle" property, if found, this PHY device is created and registered
+ using of_phy_connect()
+
+- if Device Tree is used, and the PHY device is "fixed", that is, conforms to
+ the definition of a non-MDIO managed PHY as defined in
+ Documentation/devicetree/bindings/net/fixed-link.txt, the PHY is registered
+ and connected transparently using the special fixed MDIO bus driver
+
+- finally, if the PHY is built into the switch, as is very common with
+ standalone switch packages, the PHY is probed using the slave MII bus created
+ by DSA
+
+
+SWITCHDEV
+---------
+
+DSA directly utilizes SWITCHDEV when interfacing with the bridge layer, and
+more specifically with its VLAN filtering portion when configuring VLANs on top
+of per-port slave network devices. Since DSA primarily deals with
+MDIO-connected switches, although not exclusively, SWITCHDEV's
+prepare/abort/commit phases are often simplified into a prepare phase which
+checks whether the operation is supporte by the DSA switch driver, and a commit
+phase which applies the changes.
+
+As of today, the only SWITCHDEV objects supported by DSA are the FDB and VLAN
+objects.
+
+Device Tree
+-----------
+
+DSA features a standardized binding which is documented in
+Documentation/devicetree/bindings/net/dsa/dsa.txt. PHY/MDIO library helper
+functions such as of_get_phy_mode(), of_phy_connect() are also used to query
+per-port PHY specific details: interface connection, MDIO bus location etc..
+
+HWMON
+-----
+
+Some switch drivers feature internal temperature sensors which are exposed as
+regular HWMON devices in /sys/class/hwmon/.
+
+Driver development
+==================
+
+DSA switch drivers need to implement a dsa_switch_driver structure which will
+contain the various members described below.
+
+register_switch_driver() registers this dsa_switch_driver in its internal list
+of drivers to probe for. unregister_switch_driver() does the exact opposite.
+
+Unless requested differently by setting the priv_size member accordingly, DSA
+does not allocate any driver private context space.
+
+Switch configuration
+--------------------
+
+- priv_size: additional size needed by the switch driver for its private context
+
+- tag_protocol: this is to indicate what kind of tagging protocol is supported,
+ should be a valid value from the dsa_tag_protocol enum
+
+- probe: probe routine which will be invoked by the DSA platform device upon
+ registration to test for the presence/absence of a switch device. For MDIO
+ devices, it is recommended to issue a read towards internal registers using
+ the switch pseudo-PHY and return whether this is a supported device. For other
+ buses, return a non-NULL string
+
+- setup: setup function for the switch, this function is responsible for setting
+ up the dsa_switch_driver private structure with all it needs: register maps,
+ interrupts, mutexes, locks etc.. This function is also expected to properly
+ configure the switch to separate all network interfaces from each other, that
+ is, they should be isolated by the switch hardware itself, typically by creating
+ a Port-based VLAN ID for each port and allowing only the CPU port and the
+ specific port to be in the forwarding vector. Ports that are unused by the
+ platform should be disabled. Past this function, the switch is expected to be
+ fully configured and ready to serve any kind of request. It is recommended
+ to issue a software reset of the switch during this setup function in order to
+ avoid relying on what a previous software agent such as a bootloader/firmware
+ may have previously configured.
+
+- set_addr: Some switches require the programming of the management interface's
+ Ethernet MAC address, switch drivers can also disable ageing of MAC addresses
+ on the management interface and "hardcode"/"force" this MAC address for the
+ CPU/management interface as an optimization
+
+PHY devices and link management
+-------------------------------
+
+- get_phy_flags: Some switches are interfaced to various kinds of Ethernet PHYs,
+ if the PHY library PHY driver needs to know about information it cannot obtain
+ on its own (e.g.: coming from switch memory mapped registers), this function
+ should return a 32-bits bitmask of "flags", that is private between the switch
+ driver and the Ethernet PHY driver in drivers/net/phy/*.
+
+- phy_read: Function invoked by the DSA slave MDIO bus when attempting to read
+ the switch port MDIO registers. If unavailable, return 0xffff for each read.
+ For builtin switch Ethernet PHYs, this function should allow reading the link
+ status, auto-negotiation results, link partner pages etc..
+
+- phy_write: Function invoked by the DSA slave MDIO bus when attempting to write
+ to the switch port MDIO registers. If unavailable return a negative error
+ code.
+
+- poll_link: Function invoked by DSA to query the link state of the switch
+ builtin Ethernet PHYs, per port. This function is responsible for calling
+ netif_carrier_{on,off} when appropriate, and can be used to poll all ports in a
+ single call. Executes from workqueue context.
+
+- adjust_link: Function invoked by the PHY library when a slave network device
+ is attached to a PHY device. This function is responsible for appropriately
+ configuring the switch port link parameters: speed, duplex, pause based on
+ what the phy_device is providing.
+
+- fixed_link_update: Function invoked by the PHY library, and specifically by
+ the fixed PHY driver asking the switch driver for link parameters that could
+ not be auto-negotiated, or obtained by reading the PHY registers through MDIO.
+ This is particularly useful for specific kinds of hardware such as QSGMII,
+ MoCA or other kinds of non-MDIO managed PHYs where out of band link
+ information is obtained
+
+Ethtool operations
+------------------
+
+- get_strings: ethtool function used to query the driver's strings, will
+ typically return statistics strings, private flags strings etc.
+
+- get_ethtool_stats: ethtool function used to query per-port statistics and
+ return their values. DSA overlays slave network devices general statistics:
+ RX/TX counters from the network device, with switch driver specific statistics
+ per port
+
+- get_sset_count: ethtool function used to query the number of statistics items
+
+- get_wol: ethtool function used to obtain Wake-on-LAN settings per-port, this
+ function may, for certain implementations also query the master network device
+ Wake-on-LAN settings if this interface needs to participate in Wake-on-LAN
+
+- set_wol: ethtool function used to configure Wake-on-LAN settings per-port,
+ direct counterpart to set_wol with similar restrictions
+
+- set_eee: ethtool function which is used to configure a switch port EEE (Green
+ Ethernet) settings, can optionally invoke the PHY library to enable EEE at the
+ PHY level if relevant. This function should enable EEE at the switch port MAC
+ controller and data-processing logic
+
+- get_eee: ethtool function which is used to query a switch port EEE settings,
+ this function should return the EEE state of the switch port MAC controller
+ and data-processing logic as well as query the PHY for its currently configured
+ EEE settings
+
+- get_eeprom_len: ethtool function returning for a given switch the EEPROM
+ length/size in bytes
+
+- get_eeprom: ethtool function returning for a given switch the EEPROM contents
+
+- set_eeprom: ethtool function writing specified data to a given switch EEPROM
+
+- get_regs_len: ethtool function returning the register length for a given
+ switch
+
+- get_regs: ethtool function returning the Ethernet switch internal register
+ contents. This function might require user-land code in ethtool to
+ pretty-print register values and registers
+
+Power management
+----------------
+
+- suspend: function invoked by the DSA platform device when the system goes to
+ suspend, should quiesce all Ethernet switch activities, but keep ports
+ participating in Wake-on-LAN active as well as additional wake-up logic if
+ supported
+
+- resume: function invoked by the DSA platform device when the system resumes,
+ should resume all Ethernet switch activities and re-configure the switch to be
+ in a fully active state
+
+- port_enable: function invoked by the DSA slave network device ndo_open
+ function when a port is administratively brought up, this function should be
+ fully enabling a given switch port. DSA takes care of marking the port with
+ BR_STATE_BLOCKING if the port is a bridge member, or BR_STATE_FORWARDING if it
+ was not, and propagating these changes down to the hardware
+
+- port_disable: function invoked by the DSA slave network device ndo_close
+ function when a port is administratively brought down, this function should be
+ fully disabling a given switch port. DSA takes care of marking the port with
+ BR_STATE_DISABLED and propagating changes to the hardware if this port is
+ disabled while being a bridge member
+
+Hardware monitoring
+-------------------
+
+These callbacks are only available if CONFIG_NET_DSA_HWMON is enabled:
+
+- get_temp: this function queries the given switch for its temperature
+
+- get_temp_limit: this function returns the switch current maximum temperature
+ limit
+
+- set_temp_limit: this function configures the maximum temperature limit allowed
+
+- get_temp_alarm: this function returns the critical temperature threshold
+ returning an alarm notification
+
+See Documentation/hwmon/sysfs-interface for details.
+
+Bridge layer
+------------
+
+- port_join_bridge: bridge layer function invoked when a given switch port is
+ added to a bridge, this function should be doing the necessary at the switch
+ level to permit the joining port from being added to the relevant logical
+ domain for it to ingress/egress traffic with other members of the bridge. DSA
+ does nothing but calculate a bitmask of switch ports currently members of the
+ specified bridge being requested the join
+
+- port_leave_bridge: bridge layer function invoked when a given switch port is
+ removed from a bridge, this function should be doing the necessary at the
+ switch level to deny the leaving port from ingress/egress traffic from the
+ remaining bridge members. When the port leaves the bridge, it should be aged
+ out at the switch hardware for the switch to (re) learn MAC addresses behind
+ this port. DSA calculates the bitmask of ports still members of the bridge
+ being left
+
+- port_stp_update: bridge layer function invoked when a given switch port STP
+ state is computed by the bridge layer and should be propagated to switch
+ hardware to forward/block/learn traffic. The switch driver is responsible for
+ computing a STP state change based on current and asked parameters and perform
+ the relevant ageing based on the intersection results
+
+Bridge VLAN filtering
+---------------------
+
+- port_pvid_get: bridge layer function invoked when a Port-based VLAN ID is
+ queried for the given switch port
+
+- port_pvid_set: bridge layer function invoked when a Port-based VLAN ID needs
+ to be configured on the given switch port
+
+- port_vlan_add: bridge layer function invoked when a VLAN is configured
+ (tagged or untagged) for the given switch port
+
+- port_vlan_del: bridge layer function invoked when a VLAN is removed from the
+ given switch port
+
+- vlan_getnext: bridge layer function invoked to query the next configured VLAN
+ in the switch, i.e. returns the bitmaps of members and untagged ports
+
+- port_fdb_add: bridge layer function invoked when the bridge wants to install a
+ Forwarding Database entry, the switch hardware should be programmed with the
+ specified address in the specified VLAN Id in the forwarding database
+ associated with this VLAN ID
+
+Note: VLAN ID 0 corresponds to the port private database, which, in the context
+of DSA, would be the its port-based VLAN, used by the associated bridge device.
+
+- port_fdb_del: bridge layer function invoked when the bridge wants to remove a
+ Forwarding Database entry, the switch hardware should be programmed to delete
+ the specified MAC address from the specified VLAN ID if it was mapped into
+ this port forwarding database
+
+TODO
+====
+
+The platform device problem
+---------------------------
+DSA is currently implemented as a platform device driver which is far from ideal
+as was discussed in this thread:
+
+http://permalink.gmane.org/gmane.linux.network/329848
+
+This basically prevents the device driver model to be properly used and applied,
+and support non-MDIO, non-MMIO Ethernet connected switches.
+
+Another problem with the platform device driver approach is that it prevents the
+use of a modular switch drivers build due to a circular dependency, illustrated
+here:
+
+http://comments.gmane.org/gmane.linux.network/345803
+
+Attempts of reworking this has been done here:
+
+https://lwn.net/Articles/643149/
+
+Making SWITCHDEV and DSA converge towards an unified codebase
+-------------------------------------------------------------
+
+SWITCHDEV properly takes care of abstracting the networking stack with offload
+capable hardware, but does not enforce a strict switch device driver model. On
+the other DSA enforces a fairly strict device driver model, and deals with most
+of the switch specific. At some point we should envision a merger between these
+two subsystems and get the best of both worlds.
+
+Other hanging fruits
+--------------------
+
+- making the number of ports fully dynamic and not dependent on DSA_MAX_PORTS
+- allowing more than one CPU/management interface:
+ http://comments.gmane.org/gmane.linux.network/365657
+- porting more drivers from other vendors:
+ http://comments.gmane.org/gmane.linux.network/365510

+ NVMEM SUBSYSTEM
+ Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
+
+This document explains the NVMEM Framework along with the APIs provided,
+and how to use it.
+
+1. Introduction
+===============
+*NVMEM* is the abbreviation for Non Volatile Memory layer. It is used to
+retrieve configuration of SOC or Device specific data from non volatile
+memories like eeprom, efuses and so on.
+
+Before this framework existed, NVMEM drivers like eeprom were stored in
+drivers/misc, where they all had to duplicate pretty much the same code to
+register a sysfs file, allow in-kernel users to access the content of the
+devices they were driving, etc.
+
+This was also a problem as far as other in-kernel users were involved, since
+the solutions used were pretty much different from one driver to another, there
+was a rather big abstraction leak.
+
+This framework aims at solve these problems. It also introduces DT
+representation for consumer devices to go get the data they require (MAC
+Addresses, SoC/Revision ID, part numbers, and so on) from the NVMEMs. This
+framework is based on regmap, so that most of the abstraction available in
+regmap can be reused, across multiple types of buses.
+
+NVMEM Providers
++++++++++++++++
+
+NVMEM provider refers to an entity that implements methods to initialize, read
+and write the non-volatile memory.
+
+2. Registering/Unregistering the NVMEM provider
+===============================================
+
+A NVMEM provider can register with NVMEM core by supplying relevant
+nvmem configuration to nvmem_register(), on success core would return a valid
+nvmem_device pointer.
+
+nvmem_unregister(nvmem) is used to unregister a previously registered provider.
+
+For example, a simple qfprom case:
+
+static struct nvmem_config econfig = {
+ .name = "qfprom",
+ .owner = THIS_MODULE,
+};
+
+static int qfprom_probe(struct platform_device *pdev)
+{
+ ...
+ econfig.dev = &pdev->dev;
+ nvmem = nvmem_register(&econfig);
+ ...
+}
+
+It is mandatory that the NVMEM provider has a regmap associated with its
+struct device. Failure to do would return error code from nvmem_register().
+
+NVMEM Consumers
++++++++++++++++
+
+NVMEM consumers are the entities which make use of the NVMEM provider to
+read from and to NVMEM.
+
+3. NVMEM cell based consumer APIs
+=================================
+
+NVMEM cells are the data entries/fields in the NVMEM.
+The NVMEM framework provides 3 APIs to read/write NVMEM cells.
+
+struct nvmem_cell *nvmem_cell_get(struct device *dev, const char *name);
+struct nvmem_cell *devm_nvmem_cell_get(struct device *dev, const char *name);
+
+void nvmem_cell_put(struct nvmem_cell *cell);
+void devm_nvmem_cell_put(struct device *dev, struct nvmem_cell *cell);
+
+void *nvmem_cell_read(struct nvmem_cell *cell, ssize_t *len);
+int nvmem_cell_write(struct nvmem_cell *cell, void *buf, ssize_t len);
+
+*nvmem_cell_get() apis will get a reference to nvmem cell for a given id,
+and nvmem_cell_read/write() can then read or write to the cell.
+Once the usage of the cell is finished the consumer should call *nvmem_cell_put()
+to free all the allocation memory for the cell.
+
+4. Direct NVMEM device based consumer APIs
+==========================================
+
+In some instances it is necessary to directly read/write the NVMEM.
+To facilitate such consumers NVMEM framework provides below apis.
+
+struct nvmem_device *nvmem_device_get(struct device *dev, const char *name);
+struct nvmem_device *devm_nvmem_device_get(struct device *dev,
+ const char *name);
+void nvmem_device_put(struct nvmem_device *nvmem);
+int nvmem_device_read(struct nvmem_device *nvmem, unsigned int offset,
+ size_t bytes, void *buf);
+int nvmem_device_write(struct nvmem_device *nvmem, unsigned int offset,
+ size_t bytes, void *buf);
+int nvmem_device_cell_read(struct nvmem_device *nvmem,
+ struct nvmem_cell_info *info, void *buf);
+int nvmem_device_cell_write(struct nvmem_device *nvmem,
+ struct nvmem_cell_info *info, void *buf);
+
+Before the consumers can read/write NVMEM directly, it should get hold
+of nvmem_controller from one of the *nvmem_device_get() api.
+
+The difference between these apis and cell based apis is that these apis always
+take nvmem_device as parameter.
+
+5. Releasing a reference to the NVMEM
+=====================================
+
+When a consumers no longer needs the NVMEM, it has to release the reference
+to the NVMEM it has obtained using the APIs mentioned in the above section.
+The NVMEM framework provides 2 APIs to release a reference to the NVMEM.
+
+void nvmem_cell_put(struct nvmem_cell *cell);
+void devm_nvmem_cell_put(struct device *dev, struct nvmem_cell *cell);
+void nvmem_device_put(struct nvmem_device *nvmem);
+void devm_nvmem_device_put(struct device *dev, struct nvmem_device *nvmem);
+
+Both these APIs are used to release a reference to the NVMEM and
+devm_nvmem_cell_put and devm_nvmem_device_put destroys the devres associated
+with this NVMEM.
+
+Userspace
++++++++++
+
+6. Userspace binary interface
+==============================
+
+Userspace can read/write the raw NVMEM file located at
+/sys/bus/nvmem/devices/*/nvmem
+
+ex:
+
+hexdump /sys/bus/nvmem/devices/qfprom0/nvmem

+Introduction
+============
+
+ The IBM Power architecture provides support for CAPI (Coherent
+ Accelerator Power Interface), which is available to certain PCIe slots
+ on Power 8 systems. CAPI can be thought of as a special tunneling
+ protocol through PCIe that allow PCIe adapters to look like special
+ purpose co-processors which can read or write an application's
+ memory and generate page faults. As a result, the host interface to
+ an adapter running in CAPI mode does not require the data buffers to
+ be mapped to the device's memory (IOMMU bypass) nor does it require
+ memory to be pinned.
+
+ On Linux, Coherent Accelerator (CXL) kernel services present CAPI
+ devices as a PCI device by implementing a virtual PCI host bridge.
+ This abstraction simplifies the infrastructure and programming
+ model, allowing for drivers to look similar to other native PCI
+ device drivers.
+
+ CXL provides a mechanism by which user space applications can
+ directly talk to a device (network or storage) bypassing the typical
+ kernel/device driver stack. The CXL Flash Adapter Driver enables a
+ user space application direct access to Flash storage.
+
+ The CXL Flash Adapter Driver is a kernel module that sits in the
+ SCSI stack as a low level device driver (below the SCSI disk and
+ protocol drivers) for the IBM CXL Flash Adapter. This driver is
+ responsible for the initialization of the adapter, setting up the
+ special path for user space access, and performing error recovery. It
+ communicates directly the Flash Accelerator Functional Unit (AFU)
+ as described in Documentation/powerpc/cxl.txt.
+
+ The cxlflash driver supports two, mutually exclusive, modes of
+ operation at the device (LUN) level:
+
+ - Any flash device (LUN) can be configured to be accessed as a
+ regular disk device (i.e.: /dev/sdc). This is the default mode.
+
+ - Any flash device (LUN) can be configured to be accessed from
+ user space with a special block library. This mode further
+ specifies the means of accessing the device and provides for
+ either raw access to the entire LUN (referred to as direct
+ or physical LUN access) or access to a kernel/AFU-mediated
+ partition of the LUN (referred to as virtual LUN access). The
+ segmentation of a disk device into virtual LUNs is assisted
+ by special translation services provided by the Flash AFU.
+
+Overview
+========
+
+ The Coherent Accelerator Interface Architecture (CAIA) introduces a
+ concept of a master context. A master typically has special privileges
+ granted to it by the kernel or hypervisor allowing it to perform AFU
+ wide management and control. The master may or may not be involved
+ directly in each user I/O, but at the minimum is involved in the
+ initial setup before the user application is allowed to send requests
+ directly to the AFU.
+
+ The CXL Flash Adapter Driver establishes a master context with the
+ AFU. It uses memory mapped I/O (MMIO) for this control and setup. The
+ Adapter Problem Space Memory Map looks like this:
+
+ +-------------------------------+
+ | 512 * 64 KB User MMIO |
+ | (per context) |
+ | User Accessible |
+ +-------------------------------+
+ | 512 * 128 B per context |
+ | Provisioning and Control |
+ | Trusted Process accessible |
+ +-------------------------------+
+ | 64 KB Global |
+ | Trusted Process accessible |
+ +-------------------------------+
+
+ This driver configures itself into the SCSI software stack as an
+ adapter driver. The driver is the only entity that is considered a
+ Trusted Process to program the Provisioning and Control and Global
+ areas in the MMIO Space shown above. The master context driver
+ discovers all LUNs attached to the CXL Flash adapter and instantiates
+ scsi block devices (/dev/sdb, /dev/sdc etc.) for each unique LUN
+ seen from each path.
+
+ Once these scsi block devices are instantiated, an application
+ written to a specification provided by the block library may get
+ access to the Flash from user space (without requiring a system call).
+
+ This master context driver also provides a series of ioctls for this
+ block library to enable this user space access. The driver supports
+ two modes for accessing the block device.
+
+ The first mode is called a virtual mode. In this mode a single scsi
+ block device (/dev/sdb) may be carved up into any number of distinct
+ virtual LUNs. The virtual LUNs may be resized as long as the sum of
+ the sizes of all the virtual LUNs, along with the meta-data associated
+ with it does not exceed the physical capacity.
+
+ The second mode is called the physical mode. In this mode a single
+ block device (/dev/sdb) may be opened directly by the block library
+ and the entire space for the LUN is available to the application.
+
+ Only the physical mode provides persistence of the data. i.e. The
+ data written to the block device will survive application exit and
+ restart and also reboot. The virtual LUNs do not persist (i.e. do
+ not survive after the application terminates or the system reboots).
+
+
+Block library API
+=================
+
+ Applications intending to get access to the CXL Flash from user
+ space should use the block library, as it abstracts the details of
+ interfacing directly with the cxlflash driver that are necessary for
+ performing administrative actions (i.e.: setup, tear down, resize).
+ The block library can be thought of as a 'user' of services,
+ implemented as IOCTLs, that are provided by the cxlflash driver
+ specifically for devices (LUNs) operating in user space access
+ mode. While it is not a requirement that applications understand
+ the interface between the block library and the cxlflash driver,
+ a high-level overview of each supported service (IOCTL) is provided
+ below.
+
+ The block library can be found on GitHub:
+ http://www.github.com/mikehollinger/ibmcapikv
+
+
+CXL Flash Driver IOCTLs
+=======================
+
+ Users, such as the block library, that wish to interface with a flash
+ device (LUN) via user space access need to use the services provided
+ by the cxlflash driver. As these services are implemented as ioctls,
+ a file descriptor handle must first be obtained in order to establish
+ the communication channel between a user and the kernel. This file
+ descriptor is obtained by opening the device special file associated
+ with the scsi disk device (/dev/sdb) that was created during LUN
+ discovery. As per the location of the cxlflash driver within the
+ SCSI protocol stack, this open is actually not seen by the cxlflash
+ driver. Upon successful open, the user receives a file descriptor
+ (herein referred to as fd1) that should be used for issuing the
+ subsequent ioctls listed below.
+
+ The structure definitions for these IOCTLs are available in:
+ uapi/scsi/cxlflash_ioctl.h
+
+DK_CXLFLASH_ATTACH
+------------------
+
+ This ioctl obtains, initializes, and starts a context using the CXL
+ kernel services. These services specify a context id (u16) by which
+ to uniquely identify the context and its allocated resources. The
+ services additionally provide a second file descriptor (herein
+ referred to as fd2) that is used by the block library to initiate
+ memory mapped I/O (via mmap()) to the CXL flash device and poll for
+ completion events. This file descriptor is intentionally installed by
+ this driver and not the CXL kernel services to allow for intermediary
+ notification and access in the event of a non-user-initiated close(),
+ such as a killed process. This design point is described in further
+ detail in the description for the DK_CXLFLASH_DETACH ioctl.
+
+ There are a few important aspects regarding the "tokens" (context id
+ and fd2) that are provided back to the user:
+
+ - These tokens are only valid for the process under which they
+ were created. The child of a forked process cannot continue
+ to use the context id or file descriptor created by its parent
+ (see DK_CXLFLASH_VLUN_CLONE for further details).
+
+ - These tokens are only valid for the lifetime of the context and
+ the process under which they were created. Once either is
+ destroyed, the tokens are to be considered stale and subsequent
+ usage will result in errors.
+
+ - When a context is no longer needed, the user shall detach from
+ the context via the DK_CXLFLASH_DETACH ioctl.
+
+ - A close on fd2 will invalidate the tokens. This operation is not
+ required by the user.
+
+DK_CXLFLASH_USER_DIRECT
+-----------------------
+ This ioctl is responsible for transitioning the LUN to direct
+ (physical) mode access and configuring the AFU for direct access from
+ user space on a per-context basis. Additionally, the block size and
+ last logical block address (LBA) are returned to the user.
+
+ As mentioned previously, when operating in user space access mode,
+ LUNs may be accessed in whole or in part. Only one mode is allowed
+ at a time and if one mode is active (outstanding references exist),
+ requests to use the LUN in a different mode are denied.
+
+ The AFU is configured for direct access from user space by adding an
+ entry to the AFU's resource handle table. The index of the entry is
+ treated as a resource handle that is returned to the user. The user
+ is then able to use the handle to reference the LUN during I/O.
+
+DK_CXLFLASH_USER_VIRTUAL
+------------------------
+ This ioctl is responsible for transitioning the LUN to virtual mode
+ of access and configuring the AFU for virtual access from user space
+ on a per-context basis. Additionally, the block size and last logical
+ block address (LBA) are returned to the user.
+
+ As mentioned previously, when operating in user space access mode,
+ LUNs may be accessed in whole or in part. Only one mode is allowed
+ at a time and if one mode is active (outstanding references exist),
+ requests to use the LUN in a different mode are denied.
+
+ The AFU is configured for virtual access from user space by adding
+ an entry to the AFU's resource handle table. The index of the entry
+ is treated as a resource handle that is returned to the user. The
+ user is then able to use the handle to reference the LUN during I/O.
+
+ By default, the virtual LUN is created with a size of 0. The user
+ would need to use the DK_CXLFLASH_VLUN_RESIZE ioctl to adjust the grow
+ the virtual LUN to a desired size. To avoid having to perform this
+ resize for the initial creation of the virtual LUN, the user has the
+ option of specifying a size as part of the DK_CXLFLASH_USER_VIRTUAL
+ ioctl, such that when success is returned to the user, the
+ resource handle that is provided is already referencing provisioned
+ storage. This is reflected by the last LBA being a non-zero value.
+
+DK_CXLFLASH_VLUN_RESIZE
+-----------------------
+ This ioctl is responsible for resizing a previously created virtual
+ LUN and will fail if invoked upon a LUN that is not in virtual
+ mode. Upon success, an updated last LBA is returned to the user
+ indicating the new size of the virtual LUN associated with the
+ resource handle.
+
+ The partitioning of virtual LUNs is jointly mediated by the cxlflash
+ driver and the AFU. An allocation table is kept for each LUN that is
+ operating in the virtual mode and used to program a LUN translation
+ table that the AFU references when provided with a resource handle.
+
+DK_CXLFLASH_RELEASE
+-------------------
+ This ioctl is responsible for releasing a previously obtained
+ reference to either a physical or virtual LUN. This can be
+ thought of as the inverse of the DK_CXLFLASH_USER_DIRECT or
+ DK_CXLFLASH_USER_VIRTUAL ioctls. Upon success, the resource handle
+ is no longer valid and the entry in the resource handle table is
+ made available to be used again.
+
+ As part of the release process for virtual LUNs, the virtual LUN
+ is first resized to 0 to clear out and free the translation tables
+ associated with the virtual LUN reference.
+
+DK_CXLFLASH_DETACH
+------------------
+ This ioctl is responsible for unregistering a context with the
+ cxlflash driver and release outstanding resources that were
+ not explicitly released via the DK_CXLFLASH_RELEASE ioctl. Upon
+ success, all "tokens" which had been provided to the user from the
+ DK_CXLFLASH_ATTACH onward are no longer valid.
+
+DK_CXLFLASH_VLUN_CLONE
+----------------------
+ This ioctl is responsible for cloning a previously created
+ context to a more recently created context. It exists solely to
+ support maintaining user space access to storage after a process
+ forks. Upon success, the child process (which invoked the ioctl)
+ will have access to the same LUNs via the same resource handle(s)
+ and fd2 as the parent, but under a different context.
+
+ Context sharing across processes is not supported with CXL and
+ therefore each fork must be met with establishing a new context
+ for the child process. This ioctl simplifies the state management
+ and playback required by a user in such a scenario. When a process
+ forks, child process can clone the parents context by first creating
+ a context (via DK_CXLFLASH_ATTACH) and then using this ioctl to
+ perform the clone from the parent to the child.
+
+ The clone itself is fairly simple. The resource handle and lun
+ translation tables are copied from the parent context to the child's
+ and then synced with the AFU.
+
+DK_CXLFLASH_VERIFY
+------------------
+ This ioctl is used to detect various changes such as the capacity of
+ the disk changing, the number of LUNs visible changing, etc. In cases
+ where the changes affect the application (such as a LUN resize), the
+ cxlflash driver will report the changed state to the application.
+
+ The user calls in when they want to validate that a LUN hasn't been
+ changed in response to a check condition. As the user is operating out
+ of band from the kernel, they will see these types of events without
+ the kernel's knowledge. When encountered, the user's architected
+ behavior is to call in to this ioctl, indicating what they want to
+ verify and passing along any appropriate information. For now, only
+ verifying a LUN change (ie: size different) with sense data is
+ supported.
+
+DK_CXLFLASH_RECOVER_AFU
+-----------------------
+ This ioctl is used to drive recovery (if such an action is warranted)
+ of a specified user context. Any state associated with the user context
+ is re-established upon successful recovery.
+
+ User contexts are put into an error condition when the device needs to
+ be reset or is terminating. Users are notified of this error condition
+ by seeing all 0xF's on an MMIO read. Upon encountering this, the
+ architected behavior for a user is to call into this ioctl to recover
+ their context. A user may also call into this ioctl at any time to
+ check if the device is operating normally. If a failure is returned
+ from this ioctl, the user is expected to gracefully clean up their
+ context via release/detach ioctls. Until they do, the context they
+ hold is not relinquished. The user may also optionally exit the process
+ at which time the context/resources they held will be freed as part of
+ the release fop.
+
+DK_CXLFLASH_MANAGE_LUN
+----------------------
+ This ioctl is used to switch a LUN from a mode where it is available
+ for file-system access (legacy), to a mode where it is set aside for
+ exclusive user space access (superpipe). In case a LUN is visible
+ across multiple ports and adapters, this ioctl is used to uniquely
+ identify each LUN by its World Wide Node Name (WWNN).

-KVM_GET_API_VERSION
-KVM_CREATE_VM (*) see note
-KVM_CHECK_EXTENSION
-KVM_GET_VCPU_MMAP_SIZE
-
-Notes:
-* KVM_CREATE_VM may fail on s390, if the calling process has multiple
-threads and has not called KVM_S390_ENABLE_SIE before.
-
-In addition, on s390 the following architecture specific ioctls are supported:
-ioctl: KVM_S390_ENABLE_SIE
-args: none
-see also: include/linux/kvm.h
-This call causes the kernel to switch on PGSTE in the user page table. This
-operation is needed in order to run a virtual machine, and it requires the
-calling process to be single-threaded. Note that the first call to KVM_CREATE_VM
-will implicitly try to switch on PGSTE if the user process has not called
-KVM_S390_ENABLE_SIE before. User processes that want to launch multiple threads
-before creating a virtual machine have to call KVM_S390_ENABLE_SIE, or will
-observe an error calling KVM_CREATE_VM. Switching on PGSTE is a one-time
-operation, is not reversible, and will persist over the entire lifetime of
-the calling process. It does not have any user-visible effect other than a small
-performance penalty.

-2. ioctl calls to the kvm-vm file descriptor
-KVM does support the following ioctls on s390 that are common with other
-architectures and do behave the same:
-KVM_CREATE_VCPU
-KVM_SET_USER_MEMORY_REGION (*) see note
-KVM_GET_DIRTY_LOG (**) see note
-
-Notes:
-* kvm does only allow exactly one memory slot on s390, which has to start
- at guest absolute address zero and at a user address that is aligned on any
- page boundary. This hardware "limitation" allows us to have a few unique
- optimizations. The memory slot doesn't have to be filled
- with memory actually, it may contain sparse holes. That said, with different
- user memory layout this does still allow a large flexibility when
- doing the guest memory setup.
-** KVM_GET_DIRTY_LOG doesn't work properly yet. The user will receive an empty
-log. This ioctl call is only needed for guest migration, and we intend to
-implement this one in the future.
-
-In addition, on s390 the following architecture specific ioctls for the kvm-vm
-file descriptor are supported:
-ioctl: KVM_S390_INTERRUPT
-args: struct kvm_s390_interrupt *
-see also: include/linux/kvm.h
-This ioctl is used to submit a floating interrupt for a virtual machine.
-Floating interrupts may be delivered to any virtual cpu in the configuration.
-Only some interrupt types defined in include/linux/kvm.h make sense when
-submitted as floating interrupts. The following interrupts are not considered
-to be useful as floating interrupts, and a call to inject them will result in
--EINVAL error code: program interrupts and interprocessor signals. Valid
-floating interrupts are:
-KVM_S390_INT_VIRTIO
-KVM_S390_INT_SERVICE
-
-3. ioctl calls to the kvm-vcpu file descriptor
-KVM does support the following ioctls on s390 that are common with other
-architectures and do behave the same:
-KVM_RUN
-KVM_GET_REGS
-KVM_SET_REGS
-KVM_GET_SREGS
-KVM_SET_SREGS

-KVM_SET_FPU
-
-In addition, on s390 the following architecture specific ioctls for the
-kvm-vcpu file descriptor are supported:
-ioctl: KVM_S390_INTERRUPT

-see also: include/linux/kvm.h
-This ioctl is used to submit an interrupt for a specific virtual cpu.
-Only some interrupt types defined in include/linux/kvm.h make sense when
-submitted for a specific cpu. The following interrupts are not considered

-KVM_S390_PROGRAM_INT
-KVM_S390_SIGP_STOP
-KVM_S390_RESTART
-KVM_S390_SIGP_SET_PREFIX
-KVM_S390_INT_EMERGENCY
-
-ioctl: KVM_S390_STORE_STATUS
-args: unsigned long
-see also: include/linux/kvm.h
-This ioctl stores the state of the cpu at the guest real address given as
-argument, unless one of the following values defined in include/linux/kvm.h
-is given as argument:
-KVM_S390_STORE_STATUS_NOADDR - the CPU stores its status to the save area in
-absolute lowcore as defined by the principles of operation
-KVM_S390_STORE_STATUS_PREFIXED - the CPU stores its status to the save area in
-its prefix page just like the dump tool that comes with zipl. This is useful
-to create a system dump for use with lkcdutils or crash.
-
-ioctl: KVM_S390_SET_INITIAL_PSW
-args: struct kvm_s390_psw *
-see also: include/linux/kvm.h
-This ioctl can be used to set the processor status word (psw) of a stopped cpu
-prior to running it with KVM_RUN. Note that this call is not required to modify
-the psw during sie intercepts that fall back to userspace because struct kvm_run
-does contain the psw, and this value is evaluated during reentry of KVM_RUN
-after the intercept exit was recognized.
-
-ioctl: KVM_S390_INITIAL_RESET
-args: none
-see also: include/linux/kvm.h
-This ioctl can be used to perform an initial cpu reset as defined by the
-principles of operation. The target cpu has to be in stopped state.

+MOTIVATION
+
+The idle page tracking feature allows to track which memory pages are being
+accessed by a workload and which are idle. This information can be useful for
+estimating the workload's working set size, which, in turn, can be taken into
+account when configuring the workload parameters, setting memory cgroup limits,
+or deciding where to place the workload within a compute cluster.
+
+It is enabled by CONFIG_IDLE_PAGE_TRACKING=y.
+
+USER API
+
+The idle page tracking API is located at /sys/kernel/mm/page_idle. Currently,
+it consists of the only read-write file, /sys/kernel/mm/page_idle/bitmap.
+
+The file implements a bitmap where each bit corresponds to a memory page. The
+bitmap is represented by an array of 8-byte integers, and the page at PFN #i is
+mapped to bit #i%64 of array element #i/64, byte order is native. When a bit is
+set, the corresponding page is idle.
+
+A page is considered idle if it has not been accessed since it was marked idle
+(for more details on what "accessed" actually means see the IMPLEMENTATION
+DETAILS section). To mark a page idle one has to set the bit corresponding to
+the page by writing to the file. A value written to the file is OR-ed with the
+current bitmap value.
+
+Only accesses to user memory pages are tracked. These are pages mapped to a
+process address space, page cache and buffer pages, swap cache pages. For other
+page types (e.g. SLAB pages) an attempt to mark a page idle is silently ignored,
+and hence such pages are never reported idle.
+
+For huge pages the idle flag is set only on the head page, so one has to read
+/proc/kpageflags in order to correctly count idle huge pages.
+
+Reading from or writing to /sys/kernel/mm/page_idle/bitmap will return
+-EINVAL if you are not starting the read/write on an 8-byte boundary, or
+if the size of the read/write is not a multiple of 8 bytes. Writing to
+this file beyond max PFN will return -ENXIO.
+
+That said, in order to estimate the amount of pages that are not used by a
+workload one should:
+
+ 1. Mark all the workload's pages as idle by setting corresponding bits in
+ /sys/kernel/mm/page_idle/bitmap. The pages can be found by reading
+ /proc/pid/pagemap if the workload is represented by a process, or by
+ filtering out alien pages using /proc/kpagecgroup in case the workload is
+ placed in a memory cgroup.
+
+ 2. Wait until the workload accesses its working set.
+
+ 3. Read /sys/kernel/mm/page_idle/bitmap and count the number of bits set. If
+ one wants to ignore certain types of pages, e.g. mlocked pages since they
+ are not reclaimable, he or she can filter them out using /proc/kpageflags.
+
+See Documentation/vm/pagemap.txt for more information about /proc/pid/pagemap,
+/proc/kpageflags, and /proc/kpagecgroup.
+
+IMPLEMENTATION DETAILS
+
+The kernel internally keeps track of accesses to user memory pages in order to
+reclaim unreferenced pages first on memory shortage conditions. A page is
+considered referenced if it has been recently accessed via a process address
+space, in which case one or more PTEs it is mapped to will have the Accessed bit
+set, or marked accessed explicitly by the kernel (see mark_page_accessed()). The
+latter happens when:
+
+ - a userspace process reads or writes a page using a system call (e.g. read(2)
+ or write(2))
+
+ - a page that is used for storing filesystem buffers is read or written,
+ because a process needs filesystem metadata stored in it (e.g. lists a
+ directory tree)
+
+ - a page is accessed by a device driver using get_user_pages()
+
+When a dirty page is written to swap or disk as a result of memory reclaim or
+exceeding the dirty memory limit, it is not marked referenced.
+
+The idle memory tracking feature adds a new page flag, the Idle flag. This flag
+is set manually, by writing to /sys/kernel/mm/page_idle/bitmap (see the USER API
+section), and cleared automatically whenever a page is referenced as defined
+above.
+
+When a page is marked idle, the Accessed bit must be cleared in all PTEs it is
+mapped to, otherwise we will not be able to detect accesses to the page coming
+from a process address space. To avoid interference with the reclaimer, which,
+as noted above, uses the Accessed bit to promote actively referenced pages, one
+more page flag is introduced, the Young flag. When the PTE Accessed bit is
+cleared as a result of setting or updating a page's Idle flag, the Young flag
+is set on the page. The reclaimer treats the Young flag as an extra PTE
+Accessed bit and therefore will consider such a page as referenced.
+
+Since the idle memory tracking feature is based on the memory reclaimer logic,
+it only works with pages that are on an LRU list, other pages are silently
+ignored. That means it will ignore a user memory page if it is isolated, but
+since there are usually not many of them, it should not affect the overall
+result noticeably. In order not to stall scanning of the idle page bitmap,
+locked pages may be skipped too.

+= Userfaultfd =
+
+== Objective ==
+
+Userfaults allow the implementation of on-demand paging from userland
+and more generally they allow userland to take control of various
+memory page faults, something otherwise only the kernel code could do.
+
+For example userfaults allows a proper and more optimal implementation
+of the PROT_NONE+SIGSEGV trick.
+
+== Design ==
+
+Userfaults are delivered and resolved through the userfaultfd syscall.
+
+The userfaultfd (aside from registering and unregistering virtual
+memory ranges) provides two primary functionalities:
+
+1) read/POLLIN protocol to notify a userland thread of the faults
+ happening
+
+2) various UFFDIO_* ioctls that can manage the virtual memory regions
+ registered in the userfaultfd that allows userland to efficiently
+ resolve the userfaults it receives via 1) or to manage the virtual
+ memory in the background
+
+The real advantage of userfaults if compared to regular virtual memory
+management of mremap/mprotect is that the userfaults in all their
+operations never involve heavyweight structures like vmas (in fact the
+userfaultfd runtime load never takes the mmap_sem for writing).
+
+Vmas are not suitable for page- (or hugepage) granular fault tracking
+when dealing with virtual address spaces that could span
+Terabytes. Too many vmas would be needed for that.
+
+The userfaultfd once opened by invoking the syscall, can also be
+passed using unix domain sockets to a manager process, so the same
+manager process could handle the userfaults of a multitude of
+different processes without them being aware about what is going on
+(well of course unless they later try to use the userfaultfd
+themselves on the same region the manager is already tracking, which
+is a corner case that would currently return -EBUSY).
+
+== API ==
+
+When first opened the userfaultfd must be enabled invoking the
+UFFDIO_API ioctl specifying a uffdio_api.api value set to UFFD_API (or
+a later API version) which will specify the read/POLLIN protocol
+userland intends to speak on the UFFD and the uffdio_api.features
+userland requires. The UFFDIO_API ioctl if successful (i.e. if the
+requested uffdio_api.api is spoken also by the running kernel and the
+requested features are going to be enabled) will return into
+uffdio_api.features and uffdio_api.ioctls two 64bit bitmasks of
+respectively all the available features of the read(2) protocol and
+the generic ioctl available.
+
+Once the userfaultfd has been enabled the UFFDIO_REGISTER ioctl should
+be invoked (if present in the returned uffdio_api.ioctls bitmask) to
+register a memory range in the userfaultfd by setting the
+uffdio_register structure accordingly. The uffdio_register.mode
+bitmask will specify to the kernel which kind of faults to track for
+the range (UFFDIO_REGISTER_MODE_MISSING would track missing
+pages). The UFFDIO_REGISTER ioctl will return the
+uffdio_register.ioctls bitmask of ioctls that are suitable to resolve
+userfaults on the range registered. Not all ioctls will necessarily be
+supported for all memory types depending on the underlying virtual
+memory backend (anonymous memory vs tmpfs vs real filebacked
+mappings).
+
+Userland can use the uffdio_register.ioctls to manage the virtual
+address space in the background (to add or potentially also remove
+memory from the userfaultfd registered range). This means a userfault
+could be triggering just before userland maps in the background the
+user-faulted page.
+
+The primary ioctl to resolve userfaults is UFFDIO_COPY. That
+atomically copies a page into the userfault registered range and wakes
+up the blocked userfaults (unless uffdio_copy.mode &
+UFFDIO_COPY_MODE_DONTWAKE is set). Other ioctl works similarly to
+UFFDIO_COPY. They're atomic as in guaranteeing that nothing can see an
+half copied page since it'll keep userfaulting until the copy has
+finished.
+
+== QEMU/KVM ==
+
+QEMU/KVM is using the userfaultfd syscall to implement postcopy live
+migration. Postcopy live migration is one form of memory
+externalization consisting of a virtual machine running with part or
+all of its memory residing on a different node in the cloud. The
+userfaultfd abstraction is generic enough that not a single line of
+KVM kernel code had to be modified in order to add postcopy live
+migration to QEMU.
+
+Guest async page faults, FOLL_NOWAIT and all other GUP features work
+just fine in combination with userfaults. Userfaults trigger async
+page faults in the guest scheduler so those guest processes that
+aren't waiting for userfaults (i.e. network bound) can keep running in
+the guest vcpus.
+
+It is generally beneficial to run one pass of precopy live migration
+just before starting postcopy live migration, in order to avoid
+generating userfaults for readonly guest regions.
+
+The implementation of postcopy live migration currently uses one
+single bidirectional socket but in the future two different sockets
+will be used (to reduce the latency of the userfaults to the minimum
+possible without having to decrease /proc/sys/net/ipv4/tcp_wmem).
+
+The QEMU in the source node writes all pages that it knows are missing
+in the destination node, into the socket, and the migration thread of
+the QEMU running in the destination node runs UFFDIO_COPY|ZEROPAGE
+ioctls on the userfaultfd in order to map the received pages into the
+guest (UFFDIO_ZEROCOPY is used if the source page was a zero page).
+
+A different postcopy thread in the destination node listens with
+poll() to the userfaultfd in parallel. When a POLLIN event is
+generated after a userfault triggers, the postcopy thread read() from
+the userfaultfd and receives the fault address (or -EAGAIN in case the
+userfault was already resolved and waken by a UFFDIO_COPY|ZEROPAGE run
+by the parallel QEMU migration thread).
+
+After the QEMU postcopy thread (running in the destination node) gets
+the userfault address it writes the information about the missing page
+into the socket. The QEMU source node receives the information and
+roughly "seeks" to that page address and continues sending all
+remaining missing pages from that new page offset. Soon after that
+(just the time to flush the tcp_wmem queue through the network) the
+migration thread in the QEMU running in the destination node will
+receive the page that triggered the userfault and it'll map it as
+usual with the UFFDIO_COPY|ZEROPAGE (without actually knowing if it
+was spontaneously sent by the source or if it was an urgent page
+requested through an userfault).
+
+By the time the userfaults start, the QEMU in the destination node
+doesn't need to keep any per-page state bitmap relative to the live
+migration around and a single per-page bitmap has to be maintained in
+the QEMU running in the source node to know which pages are still
+missing in the destination node. The bitmap in the source node is
+checked to find which missing pages to send in round robin and we seek
+over it when receiving incoming userfaults. After sending each page of
+course the bitmap is updated accordingly. It's also useful to avoid
+sending the same page twice (in case the userfault is read by the
+postcopy thread just before UFFDIO_COPY|ZEROPAGE runs in the migration
+thread).

+When the zpool and/or compressor parameter is changed at runtime, any existing
+compressed pages are not modified; they are left in their own zpool. When a
+request is made for a page in an old zpool, it is uncompressed using its
+original compressor. Once all pages are removed from an old zpool, the zpool
+and its compressor are freed.
A debugfs interface is provided for various statistic about pool size, number
of pages stored, and various counters for the reasons pages are rejected.

===============================================================================
Phasing out MTRR use
-MTRR use is replaced on modern x86 hardware with PAT. Over time the only type
-of effective MTRR that is expected to be supported will be for write-combining.
-As MTRR use is phased out device drivers should use arch_phys_wc_add() to make
-MTRR effective on non-PAT systems while a no-op on PAT enabled systems.
+MTRR use is replaced on modern x86 hardware with PAT. Direct MTRR use by
+drivers on Linux is now completely phased out, device drivers should use
+arch_phys_wc_add() in combination with ioremap_wc() to make MTRR effective on
+non-PAT systems while a no-op but equally effective on PAT enabled systems.
+
+Even if Linux does not use MTRRs directly, some x86 platform firmware may still
+set up MTRRs early before booting the OS. They do this as some platform
+firmware may still have implemented access to MTRRs which would be controlled
+and handled by the platform firmware directly. An example of platform use of
+MTRRs is through the use of SMI handlers, one case could be for fan control,
+the platform code would need uncachable access to some of its fan control
+registers. Such platform access does not need any Operating System MTRR code in
+place other than mtrr_type_lookup() to ensure any OS specific mapping requests
+are aligned with platform MTRR setup. If MTRRs are only set up by the platform
+firmware code though and the OS does not make any specific MTRR mapping
+requests mtrr_type_lookup() should always return MTRR_TYPE_INVALID.
For details refer to Documentation/x86/pat.txt.

- * On ARC700, EX insn is inherently atomic, so by default "vanilla" xchg() need
- * not require any locking. However there's a quirk.
- * ARC lacks native CMPXCHG, thus emulated (see above), using external locking -
- * incidently it "reuses" the same atomic_ops_lock used by atomic APIs.
- * Now, llist code uses cmpxchg() and xchg() on same data, so xchg() needs to
- * abide by same serializing rules, thus ends up using atomic_ops_lock as well.
+ * xchg() maps directly to ARC EX instruction which guarantees atomicity.
+ * However in !LLSC config, it also needs to be use @atomic_ops_lock spinlock
+ * due to a subtle reason:
+ * - For !LLSC, cmpxchg() needs to use that lock (see above) and there is lot
+ * of kernel code which calls xchg()/cmpxchg() on same data (see llist.h)
+ * Hence xchg() needs to follow same locking rules.
*
- * This however is only relevant if SMP and/or ARC lacks LLSC
- * if (UP or LLSC)
- * xchg doesn't need serialization
- * else <==> !(UP or LLSC) <==> (!UP and !LLSC) <==> (SMP and !LLSC)
- * xchg needs serialization
+ * Technically the lock is also needed for UP (boils down to irq save/restore)
+ * but we can cheat a bit since cmpxchg() atomic_ops_lock() would cause irqs to
+ * be disabled thus can't possibly be interrpted/preempted/clobbered by xchg()
+ * Other way around, xchg is one instruction anyways, so can't be interrupted
+ * as such

-/*************************************************************************
- * Timer handling for EP93xx
- *************************************************************************
- * The ep93xx has four internal timers. Timers 1, 2 (both 16 bit) and
- * 3 (32 bit) count down at 508 kHz, are self-reloading, and can generate
- * an interrupt on underflow. Timer 4 (40 bit) counts down at 983.04 kHz,
- * is free-running, and can't generate interrupts.
- *
- * The 508 kHz timers are ideal for use for the timer interrupt, as the
- * most common values of HZ divide 508 kHz nicely. We pick one of the 16
- * bit timers (timer 1) since we don't need more than 16 bits of reload
- * value as long as HZ >= 8.
- *
- * The higher clock rate of timer 4 makes it a better choice than the
- * other timers for use in gettimeoffset(), while the fact that it can't
- * generate interrupts means we don't have to worry about not being able
- * to use this timer for something else. We also use timer 4 for keeping
- * track of lost jiffies.

+/*************************************************************************
+ * Timer handling for EP93xx
+ *************************************************************************
+ * The ep93xx has four internal timers. Timers 1, 2 (both 16 bit) and
+ * 3 (32 bit) count down at 508 kHz, are self-reloading, and can generate
+ * an interrupt on underflow. Timer 4 (40 bit) counts down at 983.04 kHz,
+ * is free-running, and can't generate interrupts.
+ *
+ * The 508 kHz timers are ideal for use for the timer interrupt, as the
+ * most common values of HZ divide 508 kHz nicely. We pick the 32 bit
+ * timer (timer 3) to get as long sleep intervals as possible when using
+ * CONFIG_NO_HZ.
+ *
+ * The higher clock rate of timer 4 makes it a better choice than the
+ * other timers for use as clock source and for sched_clock(), providing
+ * a stable 40 bit time base.
+ *************************************************************************

- * clksel clocks are clocks that do not have a fixed parent, or that

- * on the contents of a hardware register bitfield.
- *
- * All of the various mux and divider settings can be encoded into
- * struct clksel* data structures, and then these can be autogenerated
- * from some hardware database for each new chip generation. This
- * should avoid the need to write, review, and validate a lot of new
- * clock code for each new chip, since it can be exported from the SoC
- * design flow. This is now done on OMAP4.
- *
- * The fusion of mux and divider clocks is a software creation. In
- * hardware reality, the multiplexer (parent selection) and the
- * divider exist separately. XXX At some point these clksel clocks
- * should be split into "divider" clocks and "mux" clocks to better
- * match the hardware.
- *
- * (The name "clksel" comes from the name of the corresponding
- * register field in the OMAP2/3 family of SoCs.)
- *
- * XXX Currently these clocks are only used in the OMAP2/3/4 code, but
- * many of the OMAP1 clocks should be convertible to use this
- * mechanism.
