+What:		/sys/fs/selinux/disable
+Date:		April 2005 (predates git)
+KernelVersion:	2.6.12-rc2 (predates git)
+Contact:	selinux@vger.kernel.org
+Description:
+
+	The selinuxfs "disable" node allows SELinux to be disabled at runtime
+	prior to a policy being loaded into the kernel.  If disabled via this
+	mechanism, SELinux will remain disabled until the system is rebooted.
+
+	The preferred method of disabling SELinux is via the "selinux=0" boot
+	parameter, but the selinuxfs "disable" node was created to make it
+	easier for systems with primitive bootloaders that did not allow for
+	easy modification of the kernel command line.  Unfortunately, allowing
+	for SELinux to be disabled at runtime makes it difficult to secure the
+	kernel's LSM hooks using the "__ro_after_init" feature.
+
+	Thankfully, the need for the SELinux runtime disable appears to be
+	gone, the default Kconfig configuration disables this selinuxfs node,
+	and only one of the major distributions, Fedora, supports disabling
+	SELinux at runtime.  Fedora is in the process of removing the
+	selinuxfs "disable" node and once that is complete we will start the
+	slow process of removing this code from the kernel.
+
+	More information on /sys/fs/selinux/disable can be found under the
+	CONFIG_SECURITY_SELINUX_DISABLE Kconfig option.

+===========================
+ACPI Fan Performance States
+===========================
+
+When the optional _FPS object is present under an ACPI device representing a
+fan (for example, PNP0C0B or INT3404), the ACPI fan driver creates additional
+"state*" attributes in the sysfs directory of the ACPI device in question.
+These attributes list properties of fan performance states.
+
+For more information on _FPS refer to the ACPI specification at:
+
+http://uefi.org/specifications
+
+For instance, the contents of the INT3404 ACPI device sysfs directory
+may look as follows::
+
+ $ ls -l /sys/bus/acpi/devices/INT3404:00/
+ total 0
+...
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state0
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state1
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state10
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state11
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state2
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state3
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state4
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state5
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state6
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state7
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state8
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state9
+ -r--r--r-- 1 root root 4096 Dec 13 01:00 status
+ ...
+
+where each of the "state*" files represents one performance state of the fan
+and contains a colon-separated list of 5 integer numbers (fields) with the
+following interpretation::
+
+control_percent:trip_point_index:speed_rpm:noise_level_mdb:power_mw
+
+* ``control_percent``: The percent value to be used to set the fan speed to a
+  specific level using the _FSL object (0-100).
+
+* ``trip_point_index``: The active cooling trip point number that corresponds
+  to this performance state (0-9).
+
+* ``speed_rpm``: Speed of the fan in rotations per minute.
+
+* ``noise_level_mdb``: Audible noise emitted by the fan in this state in
+  millidecibels.
+
+* ``power_mw``: Power draw of the fan in this state in milliwatts.
+
+For example::
+
+ $cat /sys/bus/acpi/devices/INT3404:00/state1
+ 25:0:3200:12500:1250
+
+When a given field is not populated or its value provided by the platform
+firmware is invalid, the "not-defined" string is shown instead of the value.

+``intel_idle`` CPU Idle Time Management Driver
+==============================================
+
+:Copyright: |copy| 2020 Intel Corporation
+
+:Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+
+
+General Information
+===================
+
+``intel_idle`` is a part of the
+:doc:`CPU idle time management subsystem <cpuidle>` in the Linux kernel
+(``CPUIdle``).  It is the default CPU idle time management driver for the
+Nehalem and later generations of Intel processors, but the level of support for
+a particular processor model in it depends on whether or not it recognizes that
+processor model and may also depend on information coming from the platform
+firmware.  [To understand ``intel_idle`` it is necessary to know how ``CPUIdle``
+works in general, so this is the time to get familiar with :doc:`cpuidle` if you
+have not done that yet.]
+
+``intel_idle`` uses the ``MWAIT`` instruction to inform the processor that the
+logical CPU executing it is idle and so it may be possible to put some of the
+processor's functional blocks into low-power states.  That instruction takes two
+arguments (passed in the ``EAX`` and ``ECX`` registers of the target CPU), the
+first of which, referred to as a *hint*, can be used by the processor to
+determine what can be done (for details refer to Intel Software Developer’s
+Manual [1]_).  Accordingly, ``intel_idle`` refuses to work with processors in
+which the support for the ``MWAIT`` instruction has been disabled (for example,
+via the platform firmware configuration menu) or which do not support that
+instruction at all.
+
+``intel_idle`` is not modular, so it cannot be unloaded, which means that the
+only way to pass early-configuration-time parameters to it is via the kernel
+command line.
+
+
+.. _intel-idle-enumeration-of-states:
+
+Enumeration of Idle States
+==========================
+
+Each ``MWAIT`` hint value is interpreted by the processor as a license to
+reconfigure itself in a certain way in order to save energy.  The processor
+configurations (with reduced power draw) resulting from that are referred to
+as C-states (in the ACPI terminology) or idle states.  The list of meaningful
+``MWAIT`` hint values and idle states (i.e. low-power configurations of the
+processor) corresponding to them depends on the processor model and it may also
+depend on the configuration of the platform.
+
+In order to create a list of available idle states required by the ``CPUIdle``
+subsystem (see :ref:`idle-states-representation` in :doc:`cpuidle`),
+``intel_idle`` can use two sources of information: static tables of idle states
+for different processor models included in the driver itself and the ACPI tables
+of the system.  The former are always used if the processor model at hand is
+recognized by ``intel_idle`` and the latter are used if that is required for
+the given processor model (which is the case for all server processor models
+recognized by ``intel_idle``) or if the processor model is not recognized.
+
+If the ACPI tables are going to be used for building the list of available idle
+states, ``intel_idle`` first looks for a ``_CST`` object under one of the ACPI
+objects corresponding to the CPUs in the system (refer to the ACPI specification
+[2]_ for the description of ``_CST`` and its output package).  Because the
+``CPUIdle`` subsystem expects that the list of idle states supplied by the
+driver will be suitable for all of the CPUs handled by it and ``intel_idle`` is
+registered as the ``CPUIdle`` driver for all of the CPUs in the system, the
+driver looks for the first ``_CST`` object returning at least one valid idle
+state description and such that all of the idle states included in its return
+package are of the FFH (Functional Fixed Hardware) type, which means that the
+``MWAIT`` instruction is expected to be used to tell the processor that it can
+enter one of them.  The return package of that ``_CST`` is then assumed to be
+applicable to all of the other CPUs in the system and the idle state
+descriptions extracted from it are stored in a preliminary list of idle states
+coming from the ACPI tables.  [This step is skipped if ``intel_idle`` is
+configured to ignore the ACPI tables; see `below <intel-idle-parameters_>`_.]
+
+Next, the first (index 0) entry in the list of available idle states is
+initialized to represent a "polling idle state" (a pseudo-idle state in which
+the target CPU continuously fetches and executes instructions), and the
+subsequent (real) idle state entries are populated as follows.
+
+If the processor model at hand is recognized by ``intel_idle``, there is a
+(static) table of idle state descriptions for it in the driver.  In that case,
+the "internal" table is the primary source of information on idle states and the
+information from it is copied to the final list of available idle states.  If
+using the ACPI tables for the enumeration of idle states is not required
+(depending on the processor model), all of the listed idle state are enabled by
+default (so all of them will be taken into consideration by ``CPUIdle``
+governors during CPU idle state selection).  Otherwise, some of the listed idle
+states may not be enabled by default if there are no matching entries in the
+preliminary list of idle states coming from the ACPI tables.  In that case user
+space still can enable them later (on a per-CPU basis) with the help of
+the ``disable`` idle state attribute in ``sysfs`` (see
+:ref:`idle-states-representation` in :doc:`cpuidle`).  This basically means that
+the idle states "known" to the driver may not be enabled by default if they have
+not been exposed by the platform firmware (through the ACPI tables).
+
+If the given processor model is not recognized by ``intel_idle``, but it
+supports ``MWAIT``, the preliminary list of idle states coming from the ACPI
+tables is used for building the final list that will be supplied to the
+``CPUIdle`` core during driver registration.  For each idle state in that list,
+the description, ``MWAIT`` hint and exit latency are copied to the corresponding
+entry in the final list of idle states.  The name of the idle state represented
+by it (to be returned by the ``name`` idle state attribute in ``sysfs``) is
+"CX_ACPI", where X is the index of that idle state in the final list (note that
+the minimum value of X is 1, because 0 is reserved for the "polling" state), and
+its target residency is based on the exit latency value.  Specifically, for
+C1-type idle states the exit latency value is also used as the target residency
+(for compatibility with the majority of the "internal" tables of idle states for
+various processor models recognized by ``intel_idle``) and for the other idle
+state types (C2 and C3) the target residency value is 3 times the exit latency
+(again, that is because it reflects the target residency to exit latency ratio
+in the majority of cases for the processor models recognized by ``intel_idle``).
+All of the idle states in the final list are enabled by default in this case.
+
+
+.. _intel-idle-initialization:
+
+Initialization
+==============
+
+The initialization of ``intel_idle`` starts with checking if the kernel command
+line options forbid the use of the ``MWAIT`` instruction.  If that is the case,
+an error code is returned right away.
+
+The next step is to check whether or not the processor model is known to the
+driver, which determines the idle states enumeration method (see
+`above <intel-idle-enumeration-of-states_>`_), and whether or not the processor
+supports ``MWAIT`` (the initialization fails if that is not the case).  Then,
+the ``MWAIT`` support in the processor is enumerated through ``CPUID`` and the
+driver initialization fails if the level of support is not as expected (for
+example, if the total number of ``MWAIT`` substates returned is 0).
+
+Next, if the driver is not configured to ignore the ACPI tables (see
+`below <intel-idle-parameters_>`_), the idle states information provided by the
+platform firmware is extracted from them.
+
+Then, ``CPUIdle`` device objects are allocated for all CPUs and the list of
+available idle states is created as explained
+`above <intel-idle-enumeration-of-states_>`_.
+
+Finally, ``intel_idle`` is registered with the help of cpuidle_register_driver()
+as the ``CPUIdle`` driver for all CPUs in the system and a CPU online callback
+for configuring individual CPUs is registered via cpuhp_setup_state(), which
+(among other things) causes the callback routine to be invoked for all of the
+CPUs present in the system at that time (each CPU executes its own instance of
+the callback routine).  That routine registers a ``CPUIdle`` device for the CPU
+running it (which enables the ``CPUIdle`` subsystem to operate that CPU) and
+optionally performs some CPU-specific initialization actions that may be
+required for the given processor model.
+
+
+.. _intel-idle-parameters:
+
+Kernel Command Line Options and Module Parameters
+=================================================
+
+The *x86* architecture support code recognizes three kernel command line
+options related to CPU idle time management: ``idle=poll``, ``idle=halt``,
+and ``idle=nomwait``.  If any of them is present in the kernel command line, the
+``MWAIT`` instruction is not allowed to be used, so the initialization of
+``intel_idle`` will fail.
+
+Apart from that there are two module parameters recognized by ``intel_idle``
+itself that can be set via the kernel command line (they cannot be updated via
+sysfs, so that is the only way to change their values).
+
+The ``max_cstate`` parameter value is the maximum idle state index in the list
+of idle states supplied to the ``CPUIdle`` core during the registration of the
+driver.  It is also the maximum number of regular (non-polling) idle states that
+can be used by ``intel_idle``, so the enumeration of idle states is terminated
+after finding that number of usable idle states (the other idle states that
+potentially might have been used if ``max_cstate`` had been greater are not
+taken into consideration at all).  Setting ``max_cstate`` can prevent
+``intel_idle`` from exposing idle states that are regarded as "too deep" for
+some reason to the ``CPUIdle`` core, but it does so by making them effectively
+invisible until the system is shut down and started again which may not always
+be desirable.  In practice, it is only really necessary to do that if the idle
+states in question cannot be enabled during system startup, because in the
+working state of the system the CPU power management quality of service (PM
+QoS) feature can be used to prevent ``CPUIdle`` from touching those idle states
+even if they have been enumerated (see :ref:`cpu-pm-qos` in :doc:`cpuidle`).
+Setting ``max_cstate`` to 0 causes the ``intel_idle`` initialization to fail.
+
+The ``noacpi`` module parameter (which is recognized by ``intel_idle`` if the
+kernel has been configured with ACPI support), can be set to make the driver
+ignore the system's ACPI tables entirely (it is unset by default).
+
+
+.. _intel-idle-core-and-package-idle-states:
+
+Core and Package Levels of Idle States
+======================================
+
+Typically, in a processor supporting the ``MWAIT`` instruction there are (at
+least) two levels of idle states (or C-states).  One level, referred to as
+"core C-states", covers individual cores in the processor, whereas the other
+level, referred to as "package C-states", covers the entire processor package
+and it may also involve other components of the system (GPUs, memory
+controllers, I/O hubs etc.).
+
+Some of the ``MWAIT`` hint values allow the processor to use core C-states only
+(most importantly, that is the case for the ``MWAIT`` hint value corresponding
+to the ``C1`` idle state), but the majority of them give it a license to put
+the target core (i.e. the core containing the logical CPU executing ``MWAIT``
+with the given hint value) into a specific core C-state and then (if possible)
+to enter a specific package C-state at the deeper level.  For example, the
+``MWAIT`` hint value representing the ``C3`` idle state allows the processor to
+put the target core into the low-power state referred to as "core ``C3``" (or
+``CC3``), which happens if all of the logical CPUs (SMT siblings) in that core
+have executed ``MWAIT`` with the ``C3`` hint value (or with a hint value
+representing a deeper idle state), and in addition to that (in the majority of
+cases) it gives the processor a license to put the entire package (possibly
+including some non-CPU components such as a GPU or a memory controller) into the
+low-power state referred to as "package ``C3``" (or ``PC3``), which happens if
+all of the cores have gone into the ``CC3`` state and (possibly) some additional
+conditions are satisfied (for instance, if the GPU is covered by ``PC3``, it may
+be required to be in a certain GPU-specific low-power state for ``PC3`` to be
+reachable).
+
+As a rule, there is no simple way to make the processor use core C-states only
+if the conditions for entering the corresponding package C-states are met, so
+the logical CPU executing ``MWAIT`` with a hint value that is not core-level
+only (like for ``C1``) must always assume that this may cause the processor to
+enter a package C-state.  [That is why the exit latency and target residency
+values corresponding to the majority of ``MWAIT`` hint values in the "internal"
+tables of idle states in ``intel_idle`` reflect the properties of package
+C-states.]  If using package C-states is not desirable at all, either
+:ref:`PM QoS <cpu-pm-qos>` or the ``max_cstate`` module parameter of
+``intel_idle`` described `above <intel-idle-parameters_>`_ must be used to
+restrict the range of permissible idle states to the ones with core-level only
+``MWAIT`` hint values (like ``C1``).

+responsible for enumerating routers and establishing tunnels. A
+connection manager can be implemented either in firmware or software.
+Typically PCs come with a firmware connection manager for Thunderbolt 3
+and early USB4 capable systems. Apple systems on the other hand use

+
+The Linux Thunderbolt driver supports both and can detect at runtime which
+connection manager implementation is to be used. To be on the safe side the
+software connection manager in Linux also advertises security level

+the software connection manager only supports ``user`` security level and
+is expected to be accompanied with an IOMMU based DMA protection.

+Padata is a mechanism by which the kernel can farm jobs out to be done in
+parallel on multiple CPUs while retaining their ordering.  It was developed for
+use with the IPsec code, which needs to be able to perform encryption and
+decryption on large numbers of packets without reordering those packets.  The
+crypto developers made a point of writing padata in a sufficiently general
+fashion that it could be put to other uses as well.
+
+Usage
+=====
+
+Initializing
+------------
+
+The first step in using padata is to set up a padata_instance structure for
+overall control of how jobs are to be run::
+
+    #include <linux/padata.h>
+
+    struct padata_instance *padata_alloc_possible(const char *name);
+
+'name' simply identifies the instance.
+
+There are functions for enabling and disabling the instance::
+
+    int padata_start(struct padata_instance *pinst);
+    void padata_stop(struct padata_instance *pinst);
+
+These functions are setting or clearing the "PADATA_INIT" flag; if that flag is
+not set, other functions will refuse to work.  padata_start() returns zero on
+success (flag set) or -EINVAL if the padata cpumask contains no active CPU
+(flag not set).  padata_stop() clears the flag and blocks until the padata
+instance is unused.
+
+Finally, complete padata initialization by allocating a padata_shell::
+
+   struct padata_shell *padata_alloc_shell(struct padata_instance *pinst);
+
+A padata_shell is used to submit a job to padata and allows a series of such
+jobs to be serialized independently.  A padata_instance may have one or more
+padata_shells associated with it, each allowing a separate series of jobs.
+
+Modifying cpumasks
+------------------
+
+The CPUs used to run jobs can be changed in two ways, programatically with
+padata_set_cpumask() or via sysfs.  The former is defined::
+
+    int padata_set_cpumask(struct padata_instance *pinst, int cpumask_type,
+			   cpumask_var_t cpumask);
+
+Here cpumask_type is one of PADATA_CPU_PARALLEL or PADATA_CPU_SERIAL, where a
+parallel cpumask describes which processors will be used to execute jobs
+submitted to this instance in parallel and a serial cpumask defines which
+processors are allowed to be used as the serialization callback processor.
+cpumask specifies the new cpumask to use.
+
+There may be sysfs files for an instance's cpumasks.  For example, pcrypt's
+live in /sys/kernel/pcrypt/<instance-name>.  Within an instance's directory
+there are two files, parallel_cpumask and serial_cpumask, and either cpumask
+may be changed by echoing a bitmask into the file, for example::
+
+    echo f > /sys/kernel/pcrypt/pencrypt/parallel_cpumask
+
+Reading one of these files shows the user-supplied cpumask, which may be
+different from the 'usable' cpumask.
+
+Padata maintains two pairs of cpumasks internally, the user-supplied cpumasks
+and the 'usable' cpumasks.  (Each pair consists of a parallel and a serial
+cpumask.)  The user-supplied cpumasks default to all possible CPUs on instance
+allocation and may be changed as above.  The usable cpumasks are always a
+subset of the user-supplied cpumasks and contain only the online CPUs in the
+user-supplied masks; these are the cpumasks padata actually uses.  So it is
+legal to supply a cpumask to padata that contains offline CPUs.  Once an
+offline CPU in the user-supplied cpumask comes online, padata is going to use
+it.
+
+Changing the CPU masks are expensive operations, so it should not be done with
+great frequency.
+
+Running A Job
+-------------
+
+Actually submitting work to the padata instance requires the creation of a
+padata_priv structure, which represents one job::
+
+    struct padata_priv {
+        /* Other stuff here... */
+	void                    (*parallel)(struct padata_priv *padata);
+	void                    (*serial)(struct padata_priv *padata);
+    };
+
+This structure will almost certainly be embedded within some larger
+structure specific to the work to be done.  Most of its fields are private to
+padata, but the structure should be zeroed at initialisation time, and the
+parallel() and serial() functions should be provided.  Those functions will
+be called in the process of getting the work done as we will see
+momentarily.
+
+The submission of the job is done with::
+
+    int padata_do_parallel(struct padata_shell *ps,
+		           struct padata_priv *padata, int *cb_cpu);
+
+The ps and padata structures must be set up as described above; cb_cpu
+points to the preferred CPU to be used for the final callback when the job is
+done; it must be in the current instance's CPU mask (if not the cb_cpu pointer
+is updated to point to the CPU actually chosen).  The return value from
+padata_do_parallel() is zero on success, indicating that the job is in
+progress. -EBUSY means that somebody, somewhere else is messing with the
+instance's CPU mask, while -EINVAL is a complaint about cb_cpu not being in the
+serial cpumask, no online CPUs in the parallel or serial cpumasks, or a stopped
+instance.
+
+Each job submitted to padata_do_parallel() will, in turn, be passed to
+exactly one call to the above-mentioned parallel() function, on one CPU, so
+true parallelism is achieved by submitting multiple jobs.  parallel() runs with
+software interrupts disabled and thus cannot sleep.  The parallel()
+function gets the padata_priv structure pointer as its lone parameter;
+information about the actual work to be done is probably obtained by using
+container_of() to find the enclosing structure.
+
+Note that parallel() has no return value; the padata subsystem assumes that
+parallel() will take responsibility for the job from this point.  The job
+need not be completed during this call, but, if parallel() leaves work
+outstanding, it should be prepared to be called again with a new job before
+the previous one completes.
+
+Serializing Jobs
+----------------
+
+When a job does complete, parallel() (or whatever function actually finishes
+the work) should inform padata of the fact with a call to::
+
+    void padata_do_serial(struct padata_priv *padata);
+
+At some point in the future, padata_do_serial() will trigger a call to the
+serial() function in the padata_priv structure.  That call will happen on
+the CPU requested in the initial call to padata_do_parallel(); it, too, is
+run with local software interrupts disabled.
+Note that this call may be deferred for a while since the padata code takes
+pains to ensure that jobs are completed in the order in which they were
+submitted.
+
+Destroying
+----------
+
+Cleaning up a padata instance predictably involves calling the three free
+functions that correspond to the allocation in reverse::
+
+    void padata_free_shell(struct padata_shell *ps);
+    void padata_stop(struct padata_instance *pinst);
+    void padata_free(struct padata_instance *pinst);
+
+It is the user's responsibility to ensure all outstanding jobs are complete
+before any of the above are called.

+description: |
+  The UDMA-P is intended to perform similar (but significantly upgraded)
+  functions as the packet-oriented DMA used on previous SoC devices. The UDMA-P
+  module supports the transmission and reception of various packet types.
+  The UDMA-P architecture facilitates the segmentation and reassembly of SoC DMA
+  data structure compliant packets to/from smaller data blocks that are natively
+  compatible with the specific requirements of each connected peripheral.
+  Multiple Tx and Rx channels are provided within the DMA which allow multiple
+  segmentation or reassembly operations to be ongoing. The DMA controller
+  maintains state information for each of the channels which allows packet
+  segmentation and reassembly operations to be time division multiplexed between
+  channels in order to share the underlying DMA hardware. An external DMA
+  scheduler is used to control the ordering and rate at which this multiplexing
+  occurs for Transmit operations. The ordering and rate of Receive operations
+  is indirectly controlled by the order in which blocks are pushed into the DMA
+  on the Rx PSI-L interface.
+
+  The UDMA-P also supports acting as both a UTC and UDMA-C for its internal
+  channels. Channels in the UDMA-P can be configured to be either Packet-Based
+  or Third-Party channels on a channel by channel basis.
+
+  All transfers within NAVSS is done between PSI-L source and destination
+  threads.
+  The peripherals serviced by UDMA can be PSI-L native (sa2ul, cpsw, etc) or
+  legacy, non PSI-L native peripherals. In the later case a special, small PDMA
+  is tasked to act as a bridge between the PSI-L fabric and the legacy
+  peripheral.
+
+  PDMAs can be configured via UDMAP peer registers to match with the
+  configuration of the legacy peripheral.

+
+description:
+  The DDRC block is integrated in i.MX8M for interfacing with DDR based
+  memories.
+
+  It supports switching between different frequencies at runtime but during
+  this process RAM itself becomes briefly inaccessible so actual frequency
+  switching is implemented by TF-A code which runs from a SRAM area.
+
+  The Linux driver for the DDRC doesn't even map registers (they're included
+  for the sake of "describing hardware"), it mostly just exposes firmware
+  capabilities through standard Linux mechanism like devfreq and OPP tables.

-The Synopsys designware mobile storage host controller is used to interface
-a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
-differences between the core Synopsys dw mshc controller properties described
-by synopsys-dw-mshc.txt and the properties used by the Rockchip specific
-extensions to the Synopsys Designware Mobile Storage Host Controller.
-
-Required Properties:
-

-
-* clock-names: Apart from the clock-names described in synopsys-dw-mshc.txt
-  two more clocks "ciu-drive" and "ciu-sample" are supported. They are used
-  to control the clock phases, "ciu-sample" is required for tuning high-

-* Synopsys Designware Mobile Storage Host Controller
-
-The Synopsys designware mobile storage host controller is used to interface
-a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
-differences between the core mmc properties described by mmc.txt and the
-properties used by the Synopsys Designware Mobile Storage Host Controller.
-
-Required Properties:
-
-* compatible: should be
-	- snps,dw-mshc: for controllers compliant with synopsys dw-mshc.
-* #address-cells: should be 1.
-* #size-cells: should be 0.
-
-# Slots (DEPRECATED): The slot specific information are contained within
-  child-nodes with each child-node representing a supported slot. There should
-  be atleast one child node representing a card slot. The name of the child node
-  representing the slot is recommended to be slot@n where n is the unique number
-  of the slot connected to the controller. The following are optional properties
-  which can be included in the slot child node.
-
-	* reg: specifies the physical slot number. The valid values of this
-	  property is 0 to (num-slots -1), where num-slots is the value
-	  specified by the num-slots property.
-
-	* bus-width: as documented in mmc core bindings.
-
-	* wp-gpios: specifies the write protect gpio line. The format of the
-	  gpio specifier depends on the gpio controller. If a GPIO is not used
-	  for write-protect, this property is optional.
-
-	* disable-wp: If the wp-gpios property isn't present then (by default)
-	  we'd assume that the write protect is hooked up directly to the
-	  controller's special purpose write protect line (accessible via
-	  the WRTPRT register).  However, it's possible that we simply don't
-	  want write protect.  In that case specify 'disable-wp'.
-	  NOTE: This property is not required for slots known to always
-	  connect to eMMC or SDIO cards.
-
-Optional properties:
-
-* resets: phandle + reset specifier pair, intended to represent hardware
-  reset signal present internally in some host controller IC designs.
-  See Documentation/devicetree/bindings/reset/reset.txt for details.
-
-* reset-names: request name for using "resets" property. Must be "reset".
-	(It will be used together with "resets" property.)
-
-* clocks: from common clock binding: handle to biu and ciu clocks for the
-  bus interface unit clock and the card interface unit clock.
-
-* clock-names: from common clock binding: Shall be "biu" and "ciu".
-  If the biu clock is missing we'll simply skip enabling it.  If the
-  ciu clock is missing we'll just assume that the clock is running at
-  clock-frequency.  It is an error to omit both the ciu clock and the
-  clock-frequency.
-
-* clock-frequency: should be the frequency (in Hz) of the ciu clock.  If this
-  is specified and the ciu clock is specified then we'll try to set the ciu
-  clock to this at probe time.
-
-* fifo-depth: The maximum size of the tx/rx fifo's. If this property is not
-  specified, the default value of the fifo size is determined from the
-  controller registers.
-
-* card-detect-delay: Delay in milli-seconds before detecting card after card
-  insert event. The default value is 0.
-
-* data-addr: Override fifo address with value provided by DT. The default FIFO reg
-  offset is assumed as 0x100 (version < 0x240A) and 0x200(version >= 0x240A) by
-  driver. If the controller does not follow this rule, please use this property
-  to set fifo address in device tree.
-
-* fifo-watermark-aligned: Data done irq is expected if data length is less than
-  watermark in PIO mode. But fifo watermark is requested to be aligned with data
-  length in some SoC so that TX/RX irq can be generated with data done irq. Add this
-  watermark quirk to mark this requirement and force fifo watermark setting
-  accordingly.
-
-* vmmc-supply: The phandle to the regulator to use for vmmc.  If this is
-  specified we'll defer probe until we can find this regulator.
-
-* dmas: List of DMA specifiers with the controller specific format as described
-  in the generic DMA client binding. Refer to dma.txt for details.
-
-* dma-names: request names for generic DMA client binding. Must be "rx-tx".
-  Refer to dma.txt for details.
-
-Aliases:
-
-- All the MSHC controller nodes should be represented in the aliases node using
-  the following format 'mshc{n}' where n is a unique number for the alias.
-
-Example:
-
-The MSHC controller node can be split into two portions, SoC specific and
-board specific portions as listed below.

+QCOM CPR (Core Power Reduction)
+
+CPR (Core Power Reduction) is a technology to reduce core power on a CPU
+or other device. Each OPP of a device corresponds to a "corner" that has
+a range of valid voltages for a particular frequency. While the device is
+running at a particular frequency, CPR monitors dynamic factors such as
+temperature, etc. and suggests adjustments to the voltage to save power
+and meet silicon characteristic requirements.

+ZHAW InES PTP time stamping IP core
+
+The IP core needs two different kinds of nodes.  The control node
+lives somewhere in the memory map and specifies the address of the
+control registers.  There can be up to three port handles placed as
+attributes of PHY nodes.  These associate a particular MII bus with a
+port index within the IP core.
+
+Required properties of the control node:
+
+- compatible:		"ines,ptp-ctrl"
+- reg:			physical address and size of the register bank
+
+Required format of the port handle within the PHY node:
+
+- timestamper:		provides control node reference and
+			the port channel within the IP core
+
+Example:
+
+	tstamper: timestamper@60000000 {
+		compatible = "ines,ptp-ctrl";
+		reg = <0x60000000 0x80>;
+	};

+Time stamps from MII bus snooping devices
+
+This binding supports non-PHY devices that snoop the MII bus and
+provide time stamps.  In contrast to PHY time stamping drivers (which
+can simply attach their interface directly to the PHY instance), stand
+alone MII time stamping drivers use this binding to specify the
+connection between the snooping device and a given network interface.
+
+Non-PHY MII time stamping drivers typically talk to the control
+interface over another bus like I2C, SPI, UART, or via a memory mapped
+peripheral.  This controller device is associated with one or more
+time stamping channels, each of which snoops on a MII bus.
+
+The "timestamper" property lives in a phy node and links a time
+stamping channel from the controller device to that phy's MII bus.
+
+Example:
+
+	tstamper: timestamper@10000000 {
+		compatible = "ines,ptp-ctrl";
+		reg = <0x10000000 0x80>;
+	};
+
+	ethernet@20000000 {
+		mdio {
+			ethernet-phy@1 {
+				timestamper = <&tstamper 0>;
+			};
+		};
+	};
+
+	ethernet@30000000 {
+		mdio {
+			ethernet-phy@2 {
+				timestamper = <&tstamper 1>;
+			};
+		};
+	};
+
+In this example, time stamps from the MII bus attached to phy@1 will
+appear on time stamp channel 0 (zero), and those from phy@2 appear on
+channel 1.

+* Texas Instruments K3 NavigatorSS Ring Accelerator
+
+The Ring Accelerator (RA) is a machine which converts read/write accesses
+from/to a constant address into corresponding read/write accesses from/to a
+circular data structure in memory. The RA eliminates the need for each DMA
+controller which needs to access ring elements from having to know the current
+state of the ring (base address, current offset). The DMA controller
+performs a read or write access to a specific address range (which maps to the
+source interface on the RA) and the RA replaces the address for the transaction
+with a new address which corresponds to the head or tail element of the ring
+(head for reads, tail for writes).
+
+The Ring Accelerator is a hardware module that is responsible for accelerating
+management of the packet queues. The K3 SoCs can have more than one RA instances
+

-STMicroelectronics STM32 SPI Controller
-
-The STM32 SPI controller is used to communicate with external devices using
-the Serial Peripheral Interface. It supports full-duplex, half-duplex and
-simplex synchronous serial communication with external devices. It supports
-from 4 to 32-bit data size. Although it can be configured as master or slave,
-only master is supported by the driver.
-
-Required properties:
-- compatible: Should be one of:
-  "st,stm32h7-spi"
-  "st,stm32f4-spi"
-- reg: Offset and length of the device's register set.
-- interrupts: Must contain the interrupt id.
-- clocks: Must contain an entry for spiclk (which feeds the internal clock
-	  generator).
-- #address-cells:  Number of cells required to define a chip select address.
-- #size-cells: Should be zero.
-
-Optional properties:
-- resets: Must contain the phandle to the reset controller.
-- A pinctrl state named "default" may be defined to set pins in mode of
-  operation for SPI transfer.
-- dmas: DMA specifiers for tx and rx dma. DMA fifo mode must be used. See the
-  STM32 DMA bindings, Documentation/devicetree/bindings/dma/stm32-dma.txt.
-- dma-names: DMA request names should include "tx" and "rx" if present.
-- cs-gpios: list of GPIO chip selects. See the SPI bus bindings,
-  Documentation/devicetree/bindings/spi/spi-bus.txt
-
-
-Child nodes represent devices on the SPI bus
-  See ../spi/spi-bus.txt

+  Optional: per descriptor metadata
+  ---------------------------------
+  DMAengine provides two ways for metadata support.
+
+  DESC_METADATA_CLIENT
+
+    The metadata buffer is allocated/provided by the client driver and it is
+    attached to the descriptor.
+
+  .. code-block:: c

+     int dmaengine_desc_attach_metadata(struct dma_async_tx_descriptor *desc,
+				   void *data, size_t len);
+
+  DESC_METADATA_ENGINE
+
+    The metadata buffer is allocated/managed by the DMA driver. The client
+    driver can ask for the pointer, maximum size and the currently used size of
+    the metadata and can directly update or read it.
+
+    Becasue the DMA driver manages the memory area containing the metadata,
+    clients must make sure that they do not try to access or get the pointer
+    after their transfer completion callback has run for the descriptor.
+    If no completion callback has been defined for the transfer, then the
+    metadata must not be accessed after issue_pending.
+    In other words: if the aim is to read back metadata after the transfer is
+    completed, then the client must use completion callback.
+
+  .. code-block:: c
+
+     void *dmaengine_desc_get_metadata_ptr(struct dma_async_tx_descriptor *desc,
+		size_t *payload_len, size_t *max_len);
+
+     int dmaengine_desc_set_metadata_len(struct dma_async_tx_descriptor *desc,
+		size_t payload_len);
+
+  Client drivers can query if a given mode is supported with:
+
+  .. code-block:: c
+
+     bool dmaengine_is_metadata_mode_supported(struct dma_chan *chan,
+		enum dma_desc_metadata_mode mode);
+
+  Depending on the used mode client drivers must follow different flow.

+      1. prepare the descriptor (dmaengine_prep_*)
+         construct the metadata in the client's buffer
+      2. use dmaengine_desc_attach_metadata() to attach the buffer to the

+      2. use dmaengine_desc_attach_metadata() to attach the buffer to the

+      3. submit the transfer
+      4. when the transfer is completed, the metadata should be available in the
+         attached buffer
+
+  DESC_METADATA_ENGINE
+
+    - DMA_MEM_TO_DEV / DEV_MEM_TO_MEM:
+      1. prepare the descriptor (dmaengine_prep_*)
+      2. use dmaengine_desc_get_metadata_ptr() to get the pointer to the
+         engine's metadata area
+      3. update the metadata at the pointer
+      4. use dmaengine_desc_set_metadata_len()  to tell the DMA engine the

+Per descriptor metadata support
+-------------------------------
+Some data movement architecture (DMA controller and peripherals) uses metadata
+associated with a transaction. The DMA controller role is to transfer the
+payload and the metadata alongside.
+The metadata itself is not used by the DMA engine itself, but it contains
+parameters, keys, vectors, etc for peripheral or from the peripheral.
+
+The DMAengine framework provides a generic ways to facilitate the metadata for
+descriptors. Depending on the architecture the DMA driver can implement either
+or both of the methods and it is up to the client driver to choose which one
+to use.
+
+- DESC_METADATA_CLIENT
+
+  The metadata buffer is allocated/provided by the client driver and it is
+  attached (via the dmaengine_desc_attach_metadata() helper to the descriptor.
+
+  From the DMA driver the following is expected for this mode:
+  - DMA_MEM_TO_DEV / DEV_MEM_TO_MEM
+    The data from the provided metadata buffer should be prepared for the DMA
+    controller to be sent alongside of the payload data. Either by copying to a
+    hardware descriptor, or highly coupled packet.
+  - DMA_DEV_TO_MEM
+    On transfer completion the DMA driver must copy the metadata to the client
+    provided metadata buffer before notifying the client about the completion.
+    After the transfer completion, DMA drivers must not touch the metadata
+    buffer provided by the client.
+
+- DESC_METADATA_ENGINE
+
+  The metadata buffer is allocated/managed by the DMA driver. The client driver
+  can ask for the pointer, maximum size and the currently used size of the
+  metadata and can directly update or read it. dmaengine_desc_get_metadata_ptr()
+  and dmaengine_desc_set_metadata_len() is provided as helper functions.
+
+  From the DMA driver the following is expected for this mode:
+  - get_metadata_ptr
+    Should return a pointer for the metadata buffer, the maximum size of the
+    metadata buffer and the currently used / valid (if any) bytes in the buffer.
+  - set_metadata_len
+    It is called by the clients after it have placed the metadata to the buffer
+    to let the DMA driver know the number of valid bytes provided.
+
+  Note: since the client will ask for the metadata pointer in the completion
+  callback (in DMA_DEV_TO_MEM case) the DMA driver must ensure that the
+  descriptor is not freed up prior the callback is called.

+=========================
+Using GPIO Lines in Linux
+=========================
+
+The Linux kernel exists to abstract and present hardware to users. GPIO lines
+as such are normally not user facing abstractions. The most obvious, natural
+and preferred way to use GPIO lines is to let kernel hardware drivers deal
+with them.
+
+For examples of already existing generic drivers that will also be good
+examples for any other kernel drivers you want to author, refer to
+:doc:`drivers-on-gpio`
+
+For any kind of mass produced system you want to support, such as servers,
+laptops, phones, tablets, routers, and any consumer or office or business goods
+using appropriate kernel drivers is paramount. Submit your code for inclusion
+in the upstream Linux kernel when you feel it is mature enough and you will get
+help to refine it, see :doc:`../../process/submitting-patches`.
+
+In Linux GPIO lines also have a userspace ABI.
+
+The userspace ABI is intended for one-off deployments. Examples are prototypes,
+factory lines, maker community projects, workshop specimen, production tools,
+industrial automation, PLC-type use cases, door controllers, in short a piece
+of specialized equipment that is not produced by the numbers, requiring
+operators to have a deep knowledge of the equipment and knows about the
+software-hardware interface to be set up. They should not have a natural fit
+to any existing kernel subsystem and not be a good fit for an operating system,
+because of not being reusable or abstract enough, or involving a lot of non
+computer hardware related policy.
+
+Applications that have a good reason to use the industrial I/O (IIO) subsystem
+from userspace will likely be a good fit for using GPIO lines from userspace as
+well.
+
+Do not under any circumstances abuse the GPIO userspace ABI to cut corners in
+any product development projects. If you use it for prototyping, then do not
+productify the prototype: rewrite it using proper kernel drivers. Do not under
+any circumstances deploy any uniform products using GPIO from userspace.
+
+The userspace ABI is a character device for each GPIO hardware unit (GPIO chip).
+These devices will appear on the system as ``/dev/gpiochip0`` thru
+``/dev/gpiochipN``. Examples of how to directly use the userspace ABI can be
+found in the kernel tree ``tools/gpio`` subdirectory.
+
+For structured and managed applications, we recommend that you make use of the
+libgpiod_ library. This provides helper abstractions, command line utlities
+and arbitration for multiple simultaneous consumers on the same GPIO chip.

+
+Situation:
+----------
+
+Under certain circumstances a SoC can reach a critical temperature
+limit and is unable to stabilize the temperature around a temperature
+control. When the SoC has to stabilize the temperature, the kernel can
+act on a cooling device to mitigate the dissipated power. When the
+critical temperature is reached, a decision must be taken to reduce
+the temperature, that, in turn impacts performance.
+
+Another situation is when the silicon temperature continues to
+increase even after the dynamic leakage is reduced to its minimum by
+clock gating the component. This runaway phenomenon can continue due
+to the static leakage. The only solution is to power down the
+component, thus dropping the dynamic and static leakage that will
+allow the component to cool down.
+
+Last but not least, the system can ask for a specific power budget but
+because of the OPP density, we can only choose an OPP with a power
+budget lower than the requested one and under-utilize the CPU, thus
+losing performance. In other words, one OPP under-utilizes the CPU
+with a power less than the requested power budget and the next OPP
+exceeds the power budget. An intermediate OPP could have been used if
+it were present.
+
+Solutions:
+----------
+
+If we can remove the static and the dynamic leakage for a specific
+duration in a controlled period, the SoC temperature will
+decrease. Acting on the idle state duration or the idle cycle
+injection period, we can mitigate the temperature by modulating the
+power budget.
+
+The Operating Performance Point (OPP) density has a great influence on
+the control precision of cpufreq, however different vendors have a
+plethora of OPP density, and some have large power gap between OPPs,
+that will result in loss of performance during thermal control and
+loss of power in other scenarios.
+
+At a specific OPP, we can assume that injecting idle cycle on all CPUs
+belong to the same cluster, with a duration greater than the cluster
+idle state target residency, we lead to dropping the static and the
+dynamic leakage for this period (modulo the energy needed to enter
+this state). So the sustainable power with idle cycles has a linear
+relation with the OPP’s sustainable power and can be computed with a
+coefficient similar to:
+
+	    Power(IdleCycle) = Coef x Power(OPP)
+
+Idle Injection:
+---------------
+
+The base concept of the idle injection is to force the CPU to go to an
+idle state for a specified time each control cycle, it provides
+another way to control CPU power and heat in addition to
+cpufreq. Ideally, if all CPUs belonging to the same cluster, inject
+their idle cycles synchronously, the cluster can reach its power down
+state with a minimum power consumption and reduce the static leakage
+to almost zero.  However, these idle cycles injection will add extra
+latencies as the CPUs will have to wakeup from a deep sleep state.
+
+We use a fixed duration of idle injection that gives an acceptable
+performance penalty and a fixed latency. Mitigation can be increased
+or decreased by modulating the duty cycle of the idle injection.

+              duty cycle 25%
+
+
+The implementation of the cooling device bases the number of states on
+the duty cycle percentage. When no mitigation is happening the cooling
+device state is zero, meaning the duty cycle is 0%.
+
+When the mitigation begins, depending on the governor's policy, a
+starting state is selected. With a fixed idle duration and the duty
+cycle (aka the cooling device state), the running duration can be
+computed.
+
+The governor will change the cooling device state thus the duty cycle
+and this variation will modulate the cooling effect.

+
+The idle injection duration value must comply with the constraints:
+
+- It is less than or equal to the latency we tolerate when the
+  mitigation begins. It is platform dependent and will depend on the
+  user experience, reactivity vs performance trade off we want. This
+  value should be specified.
+
+- It is greater than the idle state’s target residency we want to go
+  for thermal mitigation, otherwise we end up consuming more energy.
+
+Power considerations
+--------------------
+
+When we reach the thermal trip point, we have to sustain a specified
+power for a specific temperature but at this time we consume:
+
+ Power = Capacitance x Voltage^2 x Frequency x Utilisation
+
+... which is more than the sustainable power (or there is something
+wrong in the system setup). The ‘Capacitance’ and ‘Utilisation’ are a
+fixed value, ‘Voltage’ and the ‘Frequency’ are fixed artificially
+because we don’t want to change the OPP. We can group the
+‘Capacitance’ and the ‘Utilisation’ into a single term which is the
+‘Dynamic Power Coefficient (Cdyn)’ Simplifying the above, we have:
+
+ Pdyn = Cdyn x Voltage^2 x Frequency
+
+The power allocator governor will ask us somehow to reduce our power
+in order to target the sustainable power defined in the device
+tree. So with the idle injection mechanism, we want an average power
+(Ptarget) resulting in an amount of time running at full power on a
+specific OPP and idle another amount of time. That could be put in a
+equation:
+
+ P(opp)target = ((Trunning x (P(opp)running) + (Tidle x P(opp)idle)) /
+			(Trunning + Tidle)
+  ...
+
+ Tidle = Trunning x ((P(opp)running / P(opp)target) - 1)
+
+At this point if we know the running period for the CPU, that gives us
+the idle injection we need. Alternatively if we have the idle
+injection duration, we can compute the running duration with:
+
+ Trunning = Tidle / ((P(opp)running / P(opp)target) - 1)
+
+Practically, if the running power is less than the targeted power, we
+end up with a negative time value, so obviously the equation usage is
+bound to a power reduction, hence a higher OPP is needed to have the
+running power greater than the targeted power.
+
+However, in this demonstration we ignore three aspects:
+
+ * The static leakage is not defined here, we can introduce it in the
+   equation but assuming it will be zero most of the time as it is
+   difficult to get the values from the SoC vendors
+
+ * The idle state wake up latency (or entry + exit latency) is not
+   taken into account, it must be added in the equation in order to
+   rigorously compute the idle injection
+
+ * The injected idle duration must be greater than the idle state
+   target residency, otherwise we end up consuming more energy and
+   potentially invert the mitigation effect
+
+So the final equation is:
+
+ Trunning = (Tidle - Twakeup ) x
+		(((P(opp)dyn + P(opp)static ) - P(opp)target) / P(opp)target )

+Overview
+========
+
+Resource virtualization unit (RVU) on Marvell's OcteonTX2 SOC maps HW
+resources from the network, crypto and other functional blocks into
+PCI-compatible physical and virtual functions. Each functional block
+again has multiple local functions (LFs) for provisioning to PCI devices.
+RVU supports multiple PCIe SRIOV physical functions (PFs) and virtual
+functions (VFs). PF0 is called the administrative / admin function (AF)
+and has privileges to provision RVU functional block's LFs to each of the
+PF/VF.
+
+RVU managed networking functional blocks
+ - Network pool or buffer allocator (NPA)
+ - Network interface controller (NIX)
+ - Network parser CAM (NPC)
+ - Schedule/Synchronize/Order unit (SSO)
+ - Loopback interface (LBK)
+
+RVU managed non-networking functional blocks
+ - Crypto accelerator (CPT)
+ - Scheduled timers unit (TIM)
+ - Schedule/Synchronize/Order unit (SSO)
+   Used for both networking and non networking usecases
+
+Resource provisioning examples
+ - A PF/VF with NIX-LF & NPA-LF resources works as a pure network device
+ - A PF/VF with CPT-LF resource works as a pure crypto offload device.
+
+RVU functional blocks are highly configurable as per software requirements.
+
+Firmware setups following stuff before kernel boots
+ - Enables required number of RVU PFs based on number of physical links.
+ - Number of VFs per PF are either static or configurable at compile time.
+   Based on config, firmware assigns VFs to each of the PFs.
+ - Also assigns MSIX vectors to each of PF and VFs.
+ - These are not changed after kernel boot.
+
+Drivers
+=======
+
+Linux kernel will have multiple drivers registering to different PF and VFs
+of RVU. Wrt networking there will be 3 flavours of drivers.
+
+Admin Function driver
+---------------------
+
+As mentioned above RVU PF0 is called the admin function (AF), this driver
+supports resource provisioning and configuration of functional blocks.
+Doesn't handle any I/O. It sets up few basic stuff but most of the
+funcionality is achieved via configuration requests from PFs and VFs.
+
+PF/VFs communicates with AF via a shared memory region (mailbox). Upon
+receiving requests AF does resource provisioning and other HW configuration.
+AF is always attached to host kernel, but PFs and their VFs may be used by host
+kernel itself, or attached to VMs or to userspace applications like
+DPDK etc. So AF has to handle provisioning/configuration requests sent
+by any device from any domain.
+
+AF driver also interacts with underlying firmware to
+ - Manage physical ethernet links ie CGX LMACs.
+ - Retrieve information like speed, duplex, autoneg etc
+ - Retrieve PHY EEPROM and stats.
+ - Configure FEC, PAM modes
+ - etc
+
+From pure networking side AF driver supports following functionality.
+ - Map a physical link to a RVU PF to which a netdev is registered.
+ - Attach NIX and NPA block LFs to RVU PF/VF which provide buffer pools, RQs, SQs
+   for regular networking functionality.
+ - Flow control (pause frames) enable/disable/config.
+ - HW PTP timestamping related config.
+ - NPC parser profile config, basically how to parse pkt and what info to extract.
+ - NPC extract profile config, what to extract from the pkt to match data in MCAM entries.
+ - Manage NPC MCAM entries, upon request can frame and install requested packet forwarding rules.
+ - Defines receive side scaling (RSS) algorithms.
+ - Defines segmentation offload algorithms (eg TSO)
+ - VLAN stripping, capture and insertion config.
+ - SSO and TIM blocks config which provide packet scheduling support.
+ - Debugfs support, to check current resource provising, current status of
+   NPA pools, NIX RQ, SQ and CQs, various stats etc which helps in debugging issues.
+ - And many more.
+
+Physical Function driver
+------------------------
+
+This RVU PF handles IO, is mapped to a physical ethernet link and this
+driver registers a netdev. This supports SR-IOV. As said above this driver
+communicates with AF with a mailbox. To retrieve information from physical
+links this driver talks to AF and AF gets that info from firmware and responds
+back ie cannot talk to firmware directly.
+
+Supports ethtool for configuring links, RSS, queue count, queue size,
+flow control, ntuple filters, dump PHY EEPROM, config FEC etc.
+
+Virtual Function driver
+-----------------------
+
+There are two types VFs, VFs that share the physical link with their parent
+SR-IOV PF and the VFs which work in pairs using internal HW loopback channels (LBK).
+
+Type1:
+ - These VFs and their parent PF share a physical link and used for outside communication.
+ - VFs cannot communicate with AF directly, they send mbox message to PF and PF
+   forwards that to AF. AF after processing, responds back to PF and PF forwards
+   the reply to VF.
+ - From functionality point of view there is no difference between PF and VF as same type
+   HW resources are attached to both. But user would be able to configure few stuff only
+   from PF as PF is treated as owner/admin of the link.
+
+Type2:
+ - RVU PF0 ie admin function creates these VFs and maps them to loopback block's channels.
+ - A set of two VFs (VF0 & VF1, VF2 & VF3 .. so on) works as a pair ie pkts sent out of
+   VF0 will be received by VF1 and viceversa.
+ - These VFs can be used by applications or virtual machines to communicate between them
+   without sending traffic outside. There is no switch present in HW, hence the support
+   for loopback VFs.
+ - These communicate directly with AF (PF0) via mbox.
+
+Except for the IO channels or links used for packet reception and transmission there is
+no other difference between these VF types. AF driver takes care of IO channel mapping,
+hence same VF driver works for both types of devices.
+
+Basic packet flow
+=================
+
+Ingress
+-------
+
+1. CGX LMAC receives packet.
+2. Forwards the packet to the NIX block.
+3. Then submitted to NPC block for parsing and then MCAM lookup to get the destination RVU device.
+4. NIX LF attached to the destination RVU device allocates a buffer from RQ mapped buffer pool of NPA block LF.
+5. RQ may be selected by RSS or by configuring MCAM rule with a RQ number.
+6. Packet is DMA'ed and driver is notified.
+
+Egress
+------
+
+1. Driver prepares a send descriptor and submits to SQ for transmission.
+2. The SQ is already configured (by AF) to transmit on a specific link/channel.
+3. The SQ descriptor ring is maintained in buffers allocated from SQ mapped pool of NPA block LF.
+4. NIX block transmits the pkt on the designated channel.
+5. NPC MCAM entries can be installed to divert pkt onto a different channel.

+  -----------
+  XDP (eXpress Data Path) is a feature that runs eBPF bytecode at the early

+
+Driver Information and Notes
+============================
+
+Transmit Process
+----------------
+
+The xmit method is invoked when the kernel needs to transmit a packet; it sets
+the descriptors in the ring and informs the DMA engine that there is a packet
+ready to be transmitted.
+
+By default, the driver sets the ``NETIF_F_SG`` bit in the features field of
+the ``net_device`` structure, enabling the scatter-gather feature. This is
+true on chips and configurations where the checksum can be done in hardware.
+
+Once the controller has finished transmitting the packet, timer will be
+scheduled to release the transmit resources.
+
+Receive Process
+---------------
+
+When one or more packets are received, an interrupt happens. The interrupts
+are not queued, so the driver has to scan all the descriptors in the ring
+during the receive process.
+
+This is based on NAPI, so the interrupt handler signals only if there is work
+to be done, and it exits. Then the poll method will be scheduled at some
+future point.
+
+The incoming packets are stored, by the DMA, in a list of pre-allocated socket
+buffers in order to avoid the memcpy (zero-copy).
+
+Interrupt Mitigation
+--------------------
+
+The driver is able to mitigate the number of its DMA interrupts using NAPI for
+the reception on chips older than the 3.50. New chips have an HW RX Watchdog
+used for this mitigation.
+
+Mitigation parameters can be tuned by ethtool.
+
+WoL
+---
+
+Wake up on Lan feature through Magic and Unicast frames are supported for the
+GMAC, GMAC4/5 and XGMAC core.
+
+DMA Descriptors
+---------------
+
+Driver handles both normal and alternate descriptors. The latter has been only
+tested on DesignWare(R) Cores Ethernet MAC Universal version 3.41a and later.
+
+stmmac supports DMA descriptor to operate both in dual buffer (RING) and
+linked-list(CHAINED) mode. In RING each descriptor points to two data buffer
+pointers whereas in CHAINED mode they point to only one data buffer pointer.
+RING mode is the default.
+
+In CHAINED mode each descriptor will have pointer to next descriptor in the
+list, hence creating the explicit chaining in the descriptor itself, whereas
+such explicit chaining is not possible in RING mode.
+
+Extended Descriptors
+--------------------
+
+The extended descriptors give us information about the Ethernet payload when
+it is carrying PTP packets or TCP/UDP/ICMP over IP. These are not available on
+GMAC Synopsys(R) chips older than the 3.50. At probe time the driver will
+decide if these can be actually used. This support also is mandatory for PTPv2
+because the extra descriptors are used for saving the hardware timestamps and
+Extended Status.
+
+Ethtool Support
+---------------
+
+Ethtool is supported. For example, driver statistics (including RMON),
+internal errors can be taken using::
+
+    ethtool -S ethX
+
+Ethtool selftests are also supported. This allows to do some early sanity
+checks to the HW using MAC and PHY loopback mechanisms::
+
+    ethtool -t ethX
+
+Jumbo and Segmentation Offloading
+---------------------------------
+
+Jumbo frames are supported and tested for the GMAC. The GSO has been also
+added but it's performed in software. LRO is not supported.
+
+TSO Support
+-----------
+
+TSO (TCP Segmentation Offload) feature is supported by GMAC > 4.x and XGMAC
+chip family. When a packet is sent through TCP protocol, the TCP stack ensures
+that the SKB provided to the low level driver (stmmac in our case) matches
+with the maximum frame len (IP header + TCP header + payload <= 1500 bytes
+(for MTU set to 1500)). It means that if an application using TCP want to send
+a packet which will have a length (after adding headers) > 1514 the packet
+will be split in several TCP packets: The data payload is split and headers
+(TCP/IP ..) are added. It is done by software.
+
+When TSO is enabled, the TCP stack doesn't care about the maximum frame length
+and provide SKB packet to stmmac as it is. The GMAC IP will have to perform
+the segmentation by it self to match with maximum frame length.
+
+This feature can be enabled in device tree through ``snps,tso`` entry.
+
+Energy Efficient Ethernet
+-------------------------
+
+Energy Efficient Ethernet (EEE) enables IEEE 802.3 MAC sublayer along with a
+family of Physical layer to operate in the Low Power Idle (LPI) mode. The EEE
+mode supports the IEEE 802.3 MAC operation at 100Mbps, 1000Mbps and 1Gbps.
+
+The LPI mode allows power saving by switching off parts of the communication
+device functionality when there is no data to be transmitted & received.
+The system on both the side of the link can disable some functionalities and
+save power during the period of low-link utilization. The MAC controls whether
+the system should enter or exit the LPI mode and communicate this to PHY.
+
+As soon as the interface is opened, the driver verifies if the EEE can be
+supported. This is done by looking at both the DMA HW capability register and
+the PHY devices MCD registers.
+
+To enter in TX LPI mode the driver needs to have a software timer that enable
+and disable the LPI mode when there is nothing to be transmitted.
+
+Precision Time Protocol (PTP)
+-----------------------------
+
+The driver supports the IEEE 1588-2002, Precision Time Protocol (PTP), which
+enables precise synchronization of clocks in measurement and control systems
+implemented with technologies such as network communication.
+
+In addition to the basic timestamp features mentioned in IEEE 1588-2002
+Timestamps, new GMAC cores support the advanced timestamp features.
+IEEE 1588-2008 can be enabled when configuring the Kernel.
+
+SGMII/RGMII Support
+-------------------
+
+New GMAC devices provide own way to manage RGMII/SGMII. This information is
+available at run-time by looking at the HW capability register. This means
+that the stmmac can manage auto-negotiation and link status w/o using the
+PHYLIB stuff. In fact, the HW provides a subset of extended registers to
+restart the ANE, verify Full/Half duplex mode and Speed. Thanks to these
+registers, it is possible to look at the Auto-negotiated Link Parter Ability.
+
+Physical
+--------
+
+The driver is compatible with Physical Abstraction Layer to be connected with
+PHY and GPHY devices.
+
+Platform Information
+--------------------
+
+Several information can be passed through the platform and device-tree.
+
+::
+
+    struct plat_stmmacenet_data {
+
+1) Bus identifier::
+
+        int bus_id;
+
+2) PHY Physical Address. If set to -1 the driver will pick the first PHY it
+finds::
+
+        int phy_addr;
+
+3) PHY Device Interface::
+
+        int interface;
+
+4) Specific platform fields for the MDIO bus::
+
+        struct stmmac_mdio_bus_data *mdio_bus_data;
+
+5) Internal DMA parameters::
+
+        struct stmmac_dma_cfg *dma_cfg;
+
+6) Fixed CSR Clock Range selection::
+
+        int clk_csr;
+
+7) HW uses the GMAC core::
+
+        int has_gmac;
+
+8) If set the MAC will use Enhanced Descriptors::
+
+        int enh_desc;
+
+9) Core is able to perform TX Checksum and/or RX Checksum in HW::
+
+        int tx_coe;
+        int rx_coe;
+
+11) Some HWs are not able to perform the csum in HW for over-sized frames due
+to limited buffer sizes. Setting this flag the csum will be done in SW on
+JUMBO frames::
+
+        int bugged_jumbo;
+
+12) Core has the embedded power module::
+
+        int pmt;
+
+13) Force DMA to use the Store and Forward mode or Threshold mode::
+
+        int force_sf_dma_mode;
+        int force_thresh_dma_mode;
+
+15) Force to disable the RX Watchdog feature and switch to NAPI mode::
+
+        int riwt_off;
+

+
+        int max_speed;
+        int maxmtu;
+
+18) Number of Multicast/Unicast filters::
+

+        int unicast_filter_entries;
+
+20) Limit the maximum TX and RX FIFO size::
+

+        int rx_fifo_size;
+
+21) Use the specified number of TX and RX Queues::
+
+        u32 rx_queues_to_use;
+        u32 tx_queues_to_use;
+
+22) Use the specified TX and RX scheduling algorithm::

+        struct stmmac_txq_cfg tx_queues_cfg[MTL_MAX_TX_QUEUES];
+
+24) This callback is used for modifying some syscfg registers (on ST SoCs)
+according to the link speed negotiated by the physical layer::
+
+        void (*fix_mac_speed)(void *priv, unsigned int speed);
+
+25) Callbacks used for calling a custom initialization; This is sometimes
+necessary on some platforms (e.g. ST boxes) where the HW needs to have set
+some PIO lines or system cfg registers. init/exit callbacks should not use
+or modify platform data::
+
+        int (*init)(struct platform_device *pdev, void *priv);
+        void (*exit)(struct platform_device *pdev, void *priv);
+
+26) Perform HW setup of the bus. For example, on some ST platforms this field
+is used to configure the AMBA bridge to generate more efficient STBus traffic::

+        struct mac_device_info *(*setup)(void *priv);
+        void *bsp_priv;
+
+27) Internal clocks and rates::

+
+3) Enable 8xPBL::
+

+
+Device Tree Information
+-----------------------
+
+Please refer to the following document:
+Documentation/devicetree/bindings/net/snps,dwmac.yaml
+
+HW Capabilities
+---------------
+
+Note that, starting from new chips, where it is available the HW capability
+register, many configurations are discovered at run-time for example to
+understand if EEE, HW csum, PTP, enhanced descriptor etc are actually
+available. As strategy adopted in this driver, the information from the HW
+capability register can replace what has been passed from the platform.
+
+Debug Information
+=================
+
+The driver exports many information i.e. internal statistics, debug
+information, MAC and DMA registers etc.
+
+These can be read in several ways depending on the type of the information
+actually needed.
+
+For example a user can be use the ethtool support to get statistics: e.g.
+using: ``ethtool -S ethX`` (that shows the Management counters (MMC) if
+supported) or sees the MAC/DMA registers: e.g. using: ``ethtool -d ethX``
+
+Compiling the Kernel with ``CONFIG_DEBUG_FS`` the driver will export the
+following debugfs entries:
+
+ - ``descriptors_status``: To show the DMA TX/RX descriptor rings
+ - ``dma_cap``: To show the HW Capabilities
+
+Developer can also use the ``debug`` module parameter to get further debug
+information (please see: NETIF Msg Level).
+
+Support
+=======
+
+If an issue is identified with the released source code on a supported kernel
+with a supported adapter, email the specific information related to the
+issue to netdev@vger.kernel.org

-	    If it is set to -1 the driver will automatically
-	    detect it at run-time by probing all the 32 addresses.
- o interface: PHY device's interface.
- o mdio_bus_data: specific platform fields for the MDIO bus.
- o dma_cfg: internal DMA parameters
-   o pbl: the Programmable Burst Length is maximum number of beats to
-       be transferred in one DMA transaction.
-       GMAC also enables the 4xPBL by default. (8xPBL for GMAC 3.50 and newer)
-   o txpbl/rxpbl: GMAC and newer supports independent DMA pbl for tx/rx.
-   o pblx8: Enable 8xPBL (4xPBL for core rev < 3.50). Enabled by default.
-   o fixed_burst/mixed_burst/aal
- o clk_csr: fixed CSR Clock range selection.
- o has_gmac: uses the GMAC core.
- o enh_desc: if sets the MAC will use the enhanced descriptor structure.
- o tx_coe: core is able to perform the tx csum in HW.
- o rx_coe: the supports three check sum offloading engine types:
-	   type_1, type_2 (full csum) and no RX coe.
- o bugged_jumbo: some HWs are not able to perform the csum in HW for
-		over-sized frames due to limited buffer sizes.
-		Setting this flag the csum will be done in SW on
-		JUMBO frames.
- o pmt: core has the embedded power module (optional).
- o force_sf_dma_mode: force DMA to use the Store and Forward mode
-		     instead of the Threshold.

-		     the Store and Forward mode.
- o riwt_off: force to disable the RX watchdog feature and switch to NAPI mode.
- o fix_mac_speed: this callback is used for modifying some syscfg registers
-		 (on ST SoCs) according to the link speed negotiated by the
-		 physical layer .
- o bus_setup: perform HW setup of the bus. For example, on some ST platforms
-	     this field is used to configure the AMBA  bridge to generate more
-	     efficient STBus traffic.
- o init/exit: callbacks used for calling a custom initialization;
-	     this is sometime necessary on some platforms (e.g. ST boxes)
-	     where the HW needs to have set some PIO lines or system cfg
-	     registers.  init/exit callbacks should not use or modify
-	     platform data.
- o bsp_priv: another private pointer.
- o has_gmac4: uses GMAC4 core.
- o tso_en: Enables TSO (TCP Segmentation Offload) feature.
-
-For MDIO bus The we have:
-
- struct stmmac_mdio_bus_data {
-	int (*phy_reset)(void *priv);
-	unsigned int phy_mask;
-	int *irqs;
-	int probed_phy_irq;
- };
-
-Where:
- o phy_reset: hook to reset the phy device attached to the bus.
- o phy_mask: phy mask passed when register the MDIO bus within the driver.
- o irqs: list of IRQs, one per PHY.
- o probed_phy_irq: if irqs is NULL, use this for probed PHY.
-
-For DMA engine we have the following internal fields that should be
-tuned according to the HW capabilities.
-
-struct stmmac_dma_cfg {
-	int pbl;
-	int txpbl;
-	int rxpbl;
-	bool pblx8;
-	int fixed_burst;
-	int mixed_burst;
-	bool aal;
-};
-
-Where:
- o pbl: Programmable Burst Length (tx and rx)
- o txpbl: Transmit Programmable Burst Length. Only for GMAC and newer.
-	 If set, DMA tx will use this value rather than pbl.
- o rxpbl: Receive Programmable Burst Length. Only for GMAC and newer.
-	 If set, DMA rx will use this value rather than pbl.
- o pblx8: Enable 8xPBL (4xPBL for core rev < 3.50). Enabled by default.
- o fixed_burst: program the DMA to use the fixed burst mode
- o mixed_burst: program the DMA to use the mixed burst mode
- o aal: Address-Aligned Beats
-
----
-
-Below an example how the structures above are using on ST platforms.
-
- static struct plat_stmmacenet_data stxYYY_ethernet_platform_data = {
-	.has_gmac = 0,
-	.enh_desc = 0,
-	.fix_mac_speed = stxYYY_ethernet_fix_mac_speed,
-				|
-				|-> to write an internal syscfg
-				|   on this platform when the
-				|   link speed changes from 10 to
-				|   100 and viceversa
-	.init = &stmmac_claim_resource,
-				|
-				|-> On ST SoC this calls own "PAD"
-				|   manager framework to claim
-				|   all the resources necessary
-				|   (GPIO ...). The .custom_cfg field
-				|   is used to pass a custom config.
-};
-
-Below the usage of the stmmac_mdio_bus_data: on this SoC, in fact,
-there are two MAC cores: one MAC is for MDIO Bus/PHY emulation
-with fixed_link support.
-
-static struct stmmac_mdio_bus_data stmmac1_mdio_bus = {
-	.phy_reset = phy_reset;
-		|
-		|-> function to provide the phy_reset on this board
-	.phy_mask = 0,
-};
-
-static struct fixed_phy_status stmmac0_fixed_phy_status = {
-	.link = 1,
-	.speed = 100,
-	.duplex = 1,
-};
-
-During the board's device_init we can configure the first
-MAC for fixed_link by calling:
-  fixed_phy_add(PHY_POLL, 1, &stmmac0_fixed_phy_status);
-and the second one, with a real PHY device attached to the bus,
-by using the stmmac_mdio_bus_data structure (to provide the id, the
-reset procedure etc).
-
-Note that, starting from new chips, where it is available the HW capability
-register, many configurations are discovered at run-time for example to
-understand if EEE, HW csum, PTP, enhanced descriptor etc are actually
-available. As strategy adopted in this driver, the information from the HW
-capability register can replace what has been passed from the platform.
-
-4.10) Device-tree support.
-
-Please see the following document:
-	Documentation/devicetree/bindings/net/stmmac.txt

- o stmmac_pcs.h: Physical Coding Sublayer common implementation;
- o dwmac-<XXX>.c: these are for the platform glue-logic file; e.g. dwmac-sti.c
-   for STMicroelectronics SoCs.
-
-- GMAC 3.x

- o dwmac1000_core.c: dwmac GiGa core functions;
- o dwmac1000_dma.c: dma functions for the GMAC chip;
- o dwmac1000.h: specific header file for the dwmac GiGa;

- o dwmac4.h: core definitions for the GMAC4.x chip;
- o dwmac4_lib.c: generic GMAC4.x functions;
-
-4.12) TSO support (GMAC4.x)
-
-TSO (Tcp Segmentation Offload) feature is supported by GMAC 4.x chip family.
-When a packet is sent through TCP protocol, the TCP stack ensures that
-the SKB provided to the low level driver (stmmac in our case) matches with
-the maximum frame len (IP header + TCP header + payload <= 1500 bytes (for
-MTU set to 1500)). It means that if an application using TCP want to send a
-packet which will have a length (after adding headers) > 1514 the packet
-will be split in several TCP packets: The data payload is split and headers
-(TCP/IP ..) are added. It is done by software.
-
-When TSO is enabled, the TCP stack doesn't care about the maximum frame
-length and provide SKB packet to stmmac as it is. The GMAC IP will have to
-perform the segmentation by it self to match with maximum frame length.
-
-This feature can be enabled in device tree through "snps,tso" entry.
-
-5) Debug Information
-
-The driver exports many information i.e. internal statistics,
-debug information, MAC and DMA registers etc.
-
-These can be read in several ways depending on the
-type of the information actually needed.
-
-For example a user can be use the ethtool support
-to get statistics: e.g. using: ethtool -S ethX
-(that shows the Management counters (MMC) if supported)
-or sees the MAC/DMA registers: e.g. using: ethtool -d ethX
-
-Compiling the Kernel with CONFIG_DEBUG_FS the driver will export the following
-debugfs entries:
-
-/sys/kernel/debug/stmmaceth/descriptors_status
-  To show the DMA TX/RX descriptor rings
-
-Developer can also use the "debug" module parameter to get further debug
-information (please see: NETIF Msg Level).
-
-6) Energy Efficient Ethernet
-
-Energy Efficient Ethernet(EEE) enables IEEE 802.3 MAC sublayer along
-with a family of Physical layer to operate in the Low power Idle(LPI)
-mode. The EEE mode supports the IEEE 802.3 MAC operation at 100Mbps,
-1000Mbps & 10Gbps.
-
-The LPI mode allows power saving by switching off parts of the
-communication device functionality when there is no data to be
-transmitted & received. The system on both the side of the link can
-disable some functionalities & save power during the period of low-link
-utilization. The MAC controls whether the system should enter or exit
-the LPI mode & communicate this to PHY.
-
-As soon as the interface is opened, the driver verifies if the EEE can
-be supported. This is done by looking at both the DMA HW capability
-register and the PHY devices MCD registers.
-To enter in Tx LPI mode the driver needs to have a software timer
-that enable and disable the LPI mode when there is nothing to be
-transmitted.
-
-7) Precision Time Protocol (PTP)
-The driver supports the IEEE 1588-2002, Precision Time Protocol (PTP),
-which enables precise synchronization of clocks in measurement and
-control systems implemented with technologies such as network
-communication.
-
-In addition to the basic timestamp features mentioned in IEEE 1588-2002
-Timestamps, new GMAC cores support the advanced timestamp features.
-IEEE 1588-2008 that can be enabled when configure the Kernel.
-
-8) SGMII/RGMII support
-New GMAC devices provide own way to manage RGMII/SGMII.
-This information is available at run-time by looking at the
-HW capability register. This means that the stmmac can manage
-auto-negotiation and link status w/o using the PHYLIB stuff.
-In fact, the HW provides a subset of extended registers to
-restart the ANE, verify Full/Half duplex mode and Speed.
-Thanks to these registers, it is possible to look at the
-Auto-negotiated Link Parter Ability.

-The health mechanism is targeted for Real Time Alerting, in order to know when
-something bad had happened to a PCI device
-- Provide alert debug information
-- Self healing
-- If problem needs vendor support, provide a way to gather all needed debugging
-  information.
-
-The main idea is to unify and centralize driver health reports in the
-generic devlink instance and allow the user to set different
-attributes of the health reporting and recovery procedures.
-
-The devlink health reporter:
-Device driver creates a "health reporter" per each error/health type.
-Error/Health type can be a known/generic (eg pci error, fw error, rx/tx error)
-or unknown (driver specific).
-For each registered health reporter a driver can issue error/health reports
-asynchronously. All health reports handling is done by devlink.
-Device driver can provide specific callbacks for each "health reporter", e.g.
- - Recovery procedures
- - Diagnostics and object dump procedures
- - OOB initial parameters
-Different parts of the driver can register different types of health reporters
-with different handlers.
-
-Once an error is reported, devlink health will do the following actions:
-  * A log is being send to the kernel trace events buffer
-  * Health status and statistics are being updated for the reporter instance
-  * Object dump is being taken and saved at the reporter instance (as long as
-    there is no other dump which is already stored)
-  * Auto recovery attempt is being done. Depends on:
-    - Auto-recovery configuration
-    - Grace period vs. time passed since last recover
-
-The user interface:
-User can access/change each reporter's parameters and driver specific callbacks
-via devlink, e.g per error type (per health reporter)
- - Configure reporter's generic parameters (like: disable/enable auto recovery)
- - Invoke recovery procedure
- - Run diagnostics
- - Object dump
-
-The devlink health interface (via netlink):
-DEVLINK_CMD_HEALTH_REPORTER_GET
-  Retrieves status and configuration info per DEV and reporter.
-DEVLINK_CMD_HEALTH_REPORTER_SET
-  Allows reporter-related configuration setting.
-DEVLINK_CMD_HEALTH_REPORTER_RECOVER
-  Triggers a reporter's recovery procedure.
-DEVLINK_CMD_HEALTH_REPORTER_DIAGNOSE
-  Retrieves diagnostics data from a reporter on a device.
-DEVLINK_CMD_HEALTH_REPORTER_DUMP_GET
-  Retrieves the last stored dump. Devlink health
-  saves a single dump. If an dump is not already stored by the devlink
-  for this reporter, devlink generates a new dump.
-  dump output is defined by the reporter.
-DEVLINK_CMD_HEALTH_REPORTER_DUMP_CLEAR
-  Clears the last saved dump file for the specified reporter.

+Devlink DPIPE
+=============
+
+Background
+==========
+
+While performing the hardware offloading process, much of the hardware
+specifics cannot be presented. These details are useful for debugging, and
+``devlink-dpipe`` provides a standardized way to provide visibility into the
+offloading process.
+
+For example, the routing longest prefix match (LPM) algorithm used by the
+Linux kernel may differ from the hardware implementation. The pipeline debug
+API (DPIPE) is aimed at providing the user visibility into the ASIC's
+pipeline in a generic way.
+
+The hardware offload process is expected to be done in a way that the user
+should not be able to distinguish between the hardware vs. software
+implementation. In this process, hardware specifics are neglected. In
+reality those details can have lots of meaning and should be exposed in some
+standard way.
+
+This problem is made even more complex when one wishes to offload the
+control path of the whole networking stack to a switch ASIC. Due to
+differences in the hardware and software models some processes cannot be
+represented correctly.
+
+One example is the kernel's LPM algorithm which in many cases differs
+greatly to the hardware implementation. The configuration API is the same,
+but one cannot rely on the Forward Information Base (FIB) to look like the
+Level Path Compression trie (LPC-trie) in hardware.
+
+In many situations trying to analyze systems failure solely based on the
+kernel's dump may not be enough. By combining this data with complementary
+information about the underlying hardware, this debugging can be made
+easier; additionally, the information can be useful when debugging
+performance issues.
+
+Overview
+========
+
+The ``devlink-dpipe`` interface closes this gap. The hardware's pipeline is
+modeled as a graph of match/action tables. Each table represents a specific
+hardware block. This model is not new, first being used by the P4 language.
+
+Traditionally it has been used as an alternative model for hardware
+configuration, but the ``devlink-dpipe`` interface uses it for visibility
+purposes as a standard complementary tool. The system's view from
+``devlink-dpipe`` should change according to the changes done by the
+standard configuration tools.
+
+For example, it’s quiet common to  implement Access Control Lists (ACL)
+using Ternary Content Addressable Memory (TCAM). The TCAM memory can be
+divided into TCAM regions. Complex TC filters can have multiple rules with
+different priorities and different lookup keys. On the other hand hardware
+TCAM regions have a predefined lookup key. Offloading the TC filter rules
+using TCAM engine can result in multiple TCAM regions being interconnected
+in a chain (which may affect the data path latency). In response to a new TC
+filter new tables should be created describing those regions.
+
+Model
+=====
+
+The ``DPIPE`` model introduces several objects:
+
+  * headers
+  * tables
+  * entries
+
+A ``header`` describes packet formats and provides names for fields within
+the packet. A ``table`` describes hardware blocks. An ``entry`` describes
+the actual content of a specific table.
+
+The hardware pipeline is not port specific, but rather describes the whole
+ASIC. Thus it is tied to the top of the ``devlink`` infrastructure.
+
+Drivers can register and unregister tables at run time, in order to support
+dynamic behavior. This dynamic behavior is mandatory for describing hardware
+blocks like TCAM regions which can be allocated and freed dynamically.
+
+``devlink-dpipe`` generally is not intended for configuration. The exception
+is hardware counting for a specific table.
+
+The following commands are used to obtain the ``dpipe`` objects from
+userspace:
+
+  * ``table_get``: Receive a table's description.
+  * ``headers_get``: Receive a device's supported headers.
+  * ``entries_get``: Receive a table's current entries.
+  * ``counters_set``: Enable or disable counters on a table.
+
+Table
+-----
+
+The driver should implement the following operations for each table:
+
+  * ``matches_dump``: Dump the supported matches.
+  * ``actions_dump``: Dump the supported actions.
+  * ``entries_dump``: Dump the actual content of the table.
+  * ``counters_set_update``: Synchronize hardware with counters enabled or
+    disabled.
+
+Header/Field
+------------
+
+In a similar way to P4 headers and fields are used to describe a table's
+behavior. There is a slight difference between the standard protocol headers
+and specific ASIC metadata. The protocol headers should be declared in the
+``devlink`` core API. On the other hand ASIC meta data is driver specific
+and should be defined in the driver. Additionally, each driver-specific
+devlink documentation file should document the driver-specific ``dpipe``
+headers it implements. The headers and fields are identified by enumeration.
+
+In order to provide further visibility some ASIC metadata fields could be
+mapped to kernel objects. For example, internal router interface indexes can
+be directly mapped to the net device ifindex. FIB table indexes used by
+different Virtual Routing and Forwarding (VRF) tables can be mapped to
+internal routing table indexes.
+
+Match
+-----
+
+Matches are kept primitive and close to hardware operation. Match types like
+LPM are not supported due to the fact that this is exactly a process we wish
+to describe in full detail. Example of matches:
+
+  * ``field_exact``: Exact match on a specific field.
+  * ``field_exact_mask``: Exact match on a specific field after masking.
+  * ``field_range``: Match on a specific range.
+
+The id's of the header and the field should be specified in order to
+identify the specific field. Furthermore, the header index should be
+specified in order to distinguish multiple headers of the same type in a
+packet (tunneling).
+
+Action
+------
+
+Similar to match, the actions are kept primitive and close to hardware
+operation. For example:
+
+  * ``field_modify``: Modify the field value.
+  * ``field_inc``: Increment the field value.
+  * ``push_header``: Add a header.
+  * ``pop_header``: Remove a header.
+
+Entry
+-----
+
+Entries of a specific table can be dumped on demand. Each eentry is
+identified with an index and its properties are described by a list of
+match/action values and specific counter. By dumping the tables content the
+interactions between tables can be resolved.
+
+Abstraction Example
+===================
+
+The following is an example of the abstraction model of the L3 part of
+Mellanox Spectrum ASIC. The blocks are described in the order they appear in
+the pipeline. The table sizes in the following examples are not real
+hardware sizes and are provided for demonstration purposes.
+
+LPM
+---
+
+The LPM algorithm can be implemented as a list of hash tables. Each hash
+table contains routes with the same prefix length. The root of the list is
+/32, and in case of a miss the hardware will continue to the next hash
+table. The depth of the search will affect the data path latency.
+
+In case of a hit the entry contains information about the next stage of the
+pipeline which resolves the MAC address. The next stage can be either local
+host table for directly connected routes, or adjacency table for next-hops.
+The ``meta.lpm_prefix`` field is used to connect two LPM tables.
+
+.. code::
+
+    table lpm_prefix_16 {
+      size: 4096,
+      counters_enabled: true,
+      match: { meta.vr_id: exact,
+               ipv4.dst_addr: exact_mask,
+               ipv6.dst_addr: exact_mask,
+               meta.lpm_prefix: exact },
+      action: { meta.adj_index: set,
+                meta.adj_group_size: set,
+                meta.rif_port: set,
+                meta.lpm_prefix: set },
+    }
+
+Local Host
+----------
+
+In the case of local routes the LPM lookup already resolves the egress
+router interface (RIF), yet the exact MAC address is not known. The local
+host table is a hash table combining the output interface id with
+destination IP address as a key. The result is the MAC address.
+
+.. code::
+
+    table local_host {
+      size: 4096,
+      counters_enabled: true,
+      match: { meta.rif_port: exact,
+               ipv4.dst_addr: exact},
+      action: { ethernet.daddr: set }
+    }
+
+Adjacency
+---------
+
+In case of remote routes this table does the ECMP. The LPM lookup results in
+ECMP group size and index that serves as a global offset into this table.
+Concurrently a hash of the packet is generated. Based on the ECMP group size
+and the packet's hash a local offset is generated. Multiple LPM entries can
+point to the same adjacency group.
+
+.. code::
+
+    table adjacency {
+      size: 4096,
+      counters_enabled: true,
+      match: { meta.adj_index: exact,
+               meta.adj_group_size: exact,
+               meta.packet_hash_index: exact },
+      action: { ethernet.daddr: set,
+                meta.erif: set }
+    }
+
+ERIF
+----
+
+In case the egress RIF and destination MAC have been resolved by previous
+tables this table does multiple operations like TTL decrease and MTU check.
+Then the decision of forward/drop is taken and the port L3 statistics are
+updated based on the packet's type (broadcast, unicast, multicast).
+
+.. code::
+
+    table erif {
+      size: 800,
+      counters_enabled: true,
+      match: { meta.rif_port: exact,
+               meta.is_l3_unicast: exact,
+               meta.is_l3_broadcast: exact,
+               meta.is_l3_multicast, exact },
+      action: { meta.l3_drop: set,
+                meta.l3_forward: set }
+    }

+Devlink Health
+==============
+
+Background
+==========
+
+The ``devlink`` health mechanism is targeted for Real Time Alerting, in
+order to know when something bad happened to a PCI device.
+
+  * Provide alert debug information.
+  * Self healing.
+  * If problem needs vendor support, provide a way to gather all needed
+    debugging information.
+
+Overview
+========
+
+The main idea is to unify and centralize driver health reports in the
+generic ``devlink`` instance and allow the user to set different
+attributes of the health reporting and recovery procedures.
+
+The ``devlink`` health reporter:
+Device driver creates a "health reporter" per each error/health type.
+Error/Health type can be a known/generic (eg pci error, fw error, rx/tx error)
+or unknown (driver specific).
+For each registered health reporter a driver can issue error/health reports
+asynchronously. All health reports handling is done by ``devlink``.
+Device driver can provide specific callbacks for each "health reporter", e.g.:
+
+  * Recovery procedures
+  * Diagnostics procedures
+  * Object dump procedures
+  * OOB initial parameters
+
+Different parts of the driver can register different types of health reporters
+with different handlers.
+
+Actions
+=======
+
+Once an error is reported, devlink health will perform the following actions:
+
+  * A log is being send to the kernel trace events buffer
+  * Health status and statistics are being updated for the reporter instance
+  * Object dump is being taken and saved at the reporter instance (as long as
+    there is no other dump which is already stored)
+  * Auto recovery attempt is being done. Depends on:
+    - Auto-recovery configuration
+    - Grace period vs. time passed since last recover
+
+User Interface
+==============
+
+User can access/change each reporter's parameters and driver specific callbacks
+via ``devlink``, e.g per error type (per health reporter):
+
+  * Configure reporter's generic parameters (like: disable/enable auto recovery)
+  * Invoke recovery procedure
+  * Run diagnostics
+  * Object dump

+   * - ``DEVLINK_CMD_HEALTH_REPORTER_RECOVER``
+     - Triggers a reporter's recovery procedure.
+   * - ``DEVLINK_CMD_HEALTH_REPORTER_DIAGNOSE``
+     - Retrieves diagnostics data from a reporter on a device.
+   * - ``DEVLINK_CMD_HEALTH_REPORTER_DUMP_GET``
+     - Retrieves the last stored dump. Devlink health
+       saves a single dump. If an dump is not already stored by the devlink
+       for this reporter, devlink generates a new dump.
+       dump output is defined by the reporter.
+   * - ``DEVLINK_CMD_HEALTH_REPORTER_DUMP_CLEAR``
+     - Clears the last saved dump file for the specified reporter.

+Devlink Info
+============
+
+The ``devlink-info`` mechanism enables device drivers to report device
+information in a generic fashion. It is extensible, and enables exporting
+even device or driver specific information.
+
+devlink supports representing the following types of versions
+
+.. list-table:: List of version types
+   :widths: 5 95
+
+   * - Type
+     - Description
+   * - ``fixed``
+     - Represents fixed versions, which cannot change. For example,
+       component identifiers or the board version reported in the PCI VPD.
+   * - ``running``
+     - Represents the version of the currently running component. For
+       example the running version of firmware. These versions generally
+       only update after a reboot.
+   * - ``stored``
+     - Represents the version of a component as stored, such as after a
+       flash update. Stored values should update to reflect changes in the
+       flash even if a reboot has not yet occurred.
+
+Generic Versions
+================
+
+It is expected that drivers use the following generic names for exporting
+version information. Other information may be exposed using driver-specific

+Devlink Params
+==============
+
+``devlink`` provides capability for a driver to expose device parameters for low
+level device functionality. Since devlink can operate at the device-wide
+level, it can be used to provide configuration that may affect multiple
+ports on a single device.
+
+This document describes a number of generic parameters that are supported
+across multiple drivers. Each driver is also free to add their own
+parameters. Each driver must document the specific parameters they support,
+whether generic or not.
+
+Configuration modes
+===================
+
+Parameters may be set in different configuration modes.
+
+.. list-table:: Possible configuration modes
+   :widths: 5 90
+
+   * - Name
+     - Description
+   * - ``runtime``
+     - set while the driver is running, and takes effect immediately. No
+       reset is required.
+   * - ``driverinit``
+     - applied while the driver initializes. Requires the user to restart
+       the driver using the ``devlink`` reload command.
+   * - ``permanent``
+     - written to the device's non-volatile memory. A hard reset is required
+       for it to take effect.
+
+Reloading
+---------
+
+In order for ``driverinit`` parameters to take effect, the driver must
+support reloading via the ``devlink-reload`` command. This command will
+request a reload of the device driver.
+
+Generic configuration parameters
+================================
+The following is a list of generic configuration parameters that drivers may
+add. Use of generic parameters is preferred over each driver creating their
+own name.
+

+     - Boolean
+     - Enable Single Root I/O Virtualization (SRIOV) in the device.
+   * - ``ignore_ari``
+     - Boolean
+     - Ignore Alternative Routing-ID Interpretation (ARI) capability. If
+       enabled, the adapter will ignore ARI capability even when the
+       platform has support enabled. The device will create the same number
+       of partitions as when the platform does not support ARI.
+   * - ``msix_vec_per_pf_max``
+     - u32
+     - Provides the maximum number of MSI-X interrupts that a device can
+       create. Value is the same across all physical functions (PFs) in the
+       device.
+   * - ``msix_vec_per_pf_min``
+     - u32
+     - Provides the minimum number of MSI-X interrupts required for the
+       device to initialize. Value is the same across all physical functions
+       (PFs) in the device.
+   * - ``fw_load_policy``

+Devlink Region
+==============
+
+``devlink`` regions enable access to driver defined address regions using
+devlink.
+
+Each device can create and register its own supported address regions. The
+region can then be accessed via the devlink region interface.
+
+Region snapshots are collected by the driver, and can be accessed via read
+or dump commands. This allows future analysis on the created snapshots.
+Regions may optionally support triggering snapshots on demand.
+
+The major benefit to creating a region is to provide access to internal
+address regions that are otherwise inaccessible to the user.
+
+Regions may also be used to provide an additional way to debug complex error
+states, but see also :doc:`devlink-health`
+
+example usage

+================
+Devlink Resource
+================
+
+``devlink`` provides the ability for drivers to register resources, which
+can allow administrators to see the device restrictions for a given
+resource, as well as how much of the given resource is currently
+in use. Additionally, these resources can optionally have configurable size.
+This could enable the administrator to limit the number of resources that
+are used.
+
+For example, the ``netdevsim`` driver enables ``/IPv4/fib`` and
+``/IPv4/fib-rules`` as resources to limit the number of IPv4 FIB entries and
+rules for a given device.
+
+Resource Ids
+============
+
+Each resource is represented by an id, and contains information about its
+current size and related sub resources. To access a sub resource, you
+specify the path of the resource. For example ``/IPv4/fib`` is the id for
+the ``fib`` sub-resource under the ``IPv4`` resource.
+
+example usage
+-------------
+
+The resources exposed by the driver can be observed, for example:
+
+.. code:: shell
+
+    $devlink resource show pci/0000:03:00.0
+    pci/0000:03:00.0:
+      name kvd size 245760 unit entry
+        resources:
+          name linear size 98304 occ 0 unit entry size_min 0 size_max 147456 size_gran 128
+          name hash_double size 60416 unit entry size_min 32768 size_max 180224 size_gran 128
+          name hash_single size 87040 unit entry size_min 65536 size_max 212992 size_gran 128
+
+Some resource's size can be changed. Examples:
+
+.. code:: shell
+
+    $devlink resource set pci/0000:03:00.0 path /kvd/hash_single size 73088
+    $devlink resource set pci/0000:03:00.0 path /kvd/hash_double size 74368
+
+The changes do not apply immediately, this can be validated by the 'size_new'
+attribute, which represents the pending change in size. For example:
+
+.. code:: shell
+
+    $devlink resource show pci/0000:03:00.0
+    pci/0000:03:00.0:
+      name kvd size 245760 unit entry size_valid false
+      resources:
+        name linear size 98304 size_new 147456 occ 0 unit entry size_min 0 size_max 147456 size_gran 128
+        name hash_double size 60416 unit entry size_min 32768 size_max 180224 size_gran 128
+        name hash_single size 87040 unit entry size_min 65536 size_max 212992 size_gran 128
+
+Note that changes in resource size may require a device reload to properly
+take effect.

+=============================
+Netlink interface for ethtool
+=============================
+
+
+Basic information
+=================
+
+Netlink interface for ethtool uses generic netlink family ``ethtool``
+(userspace application should use macros ``ETHTOOL_GENL_NAME`` and
+``ETHTOOL_GENL_VERSION`` defined in ``<linux/ethtool_netlink.h>`` uapi
+header). This family does not use a specific header, all information in
+requests and replies is passed using netlink attributes.
+
+The ethtool netlink interface uses extended ACK for error and warning
+reporting, userspace application developers are encouraged to make these
+messages available to user in a suitable way.
+
+Requests can be divided into three categories: "get" (retrieving information),
+"set" (setting parameters) and "action" (invoking an action).
+
+All "set" and "action" type requests require admin privileges
+(``CAP_NET_ADMIN`` in the namespace). Most "get" type requests are allowed for
+anyone but there are exceptions (where the response contains sensitive
+information). In some cases, the request as such is allowed for anyone but
+unprivileged users have attributes with sensitive information (e.g.
+wake-on-lan password) omitted.
+
+
+Conventions
+===========
+
+Attributes which represent a boolean value usually use NLA_U8 type so that we
+can distinguish three states: "on", "off" and "not present" (meaning the
+information is not available in "get" requests or value is not to be changed
+in "set" requests). For these attributes, the "true" value should be passed as
+number 1 but any non-zero value should be understood as "true" by recipient.
+In the tables below, "bool" denotes NLA_U8 attributes interpreted in this way.
+
+In the message structure descriptions below, if an attribute name is suffixed
+with "+", parent nest can contain multiple attributes of the same type. This
+implements an array of entries.
+
+
+Request header
+==============
+
+Each request or reply message contains a nested attribute with common header.
+Structure of this header is
+
+  ==============================  ======  =============================
+  ``ETHTOOL_A_HEADER_DEV_INDEX``  u32     device ifindex
+  ``ETHTOOL_A_HEADER_DEV_NAME``   string  device name
+  ``ETHTOOL_A_HEADER_FLAGS``      u32     flags common for all requests
+  ==============================  ======  =============================
+
+``ETHTOOL_A_HEADER_DEV_INDEX`` and ``ETHTOOL_A_HEADER_DEV_NAME`` identify the
+device message relates to. One of them is sufficient in requests, if both are
+used, they must identify the same device. Some requests, e.g. global string
+sets, do not require device identification. Most ``GET`` requests also allow
+dump requests without device identification to query the same information for
+all devices providing it (each device in a separate message).
+
+``ETHTOOL_A_HEADER_FLAGS`` is a bitmap of request flags common for all request
+types. The interpretation of these flags is the same for all request types but
+the flags may not apply to requests. Recognized flags are:
+
+  =================================  ===================================
+  ``ETHTOOL_FLAG_COMPACT_BITSETS``   use compact format bitsets in reply
+  ``ETHTOOL_FLAG_OMIT_REPLY``        omit optional reply (_SET and _ACT)
+  =================================  ===================================
+
+New request flags should follow the general idea that if the flag is not set,
+the behaviour is backward compatible, i.e. requests from old clients not aware
+of the flag should be interpreted the way the client expects. A client must
+not set flags it does not understand.
+
+
+Bit sets
+========
+
+For short bitmaps of (reasonably) fixed length, standard ``NLA_BITFIELD32``
+type is used. For arbitrary length bitmaps, ethtool netlink uses a nested
+attribute with contents of one of two forms: compact (two binary bitmaps
+representing bit values and mask of affected bits) and bit-by-bit (list of
+bits identified by either index or name).
+
+Verbose (bit-by-bit) bitsets allow sending symbolic names for bits together
+with their values which saves a round trip (when the bitset is passed in a
+request) or at least a second request (when the bitset is in a reply). This is
+useful for one shot applications like traditional ethtool command. On the
+other hand, long running applications like ethtool monitor (displaying
+notifications) or network management daemons may prefer fetching the names
+only once and using compact form to save message size. Notifications from
+ethtool netlink interface always use compact form for bitsets.
+
+A bitset can represent either a value/mask pair (``ETHTOOL_A_BITSET_NOMASK``
+not set) or a single bitmap (``ETHTOOL_A_BITSET_NOMASK`` set). In requests
+modifying a bitmap, the former changes the bit set in mask to values set in
+value and preserves the rest; the latter sets the bits set in the bitmap and
+clears the rest.
+
+Compact form: nested (bitset) atrribute contents:
+
+  ============================  ======  ============================
+  ``ETHTOOL_A_BITSET_NOMASK``   flag    no mask, only a list
+  ``ETHTOOL_A_BITSET_SIZE``     u32     number of significant bits
+  ``ETHTOOL_A_BITSET_VALUE``    binary  bitmap of bit values
+  ``ETHTOOL_A_BITSET_MASK``     binary  bitmap of valid bits
+  ============================  ======  ============================
+
+Value and mask must have length at least ``ETHTOOL_A_BITSET_SIZE`` bits
+rounded up to a multiple of 32 bits. They consist of 32-bit words in host byte
+order, words ordered from least significant to most significant (i.e. the same
+way as bitmaps are passed with ioctl interface).
+
+For compact form, ``ETHTOOL_A_BITSET_SIZE`` and ``ETHTOOL_A_BITSET_VALUE`` are
+mandatory. ``ETHTOOL_A_BITSET_MASK`` attribute is mandatory if
+``ETHTOOL_A_BITSET_NOMASK`` is not set (bitset represents a value/mask pair);
+if ``ETHTOOL_A_BITSET_NOMASK`` is not set, ``ETHTOOL_A_BITSET_MASK`` is not
+allowed (bitset represents a single bitmap.
+
+Kernel bit set length may differ from userspace length if older application is
+used on newer kernel or vice versa. If userspace bitmap is longer, an error is
+issued only if the request actually tries to set values of some bits not
+recognized by kernel.
+
+Bit-by-bit form: nested (bitset) attribute contents:
+
+ +------------------------------------+--------+-----------------------------+
+ | ``ETHTOOL_A_BITSET_NOMASK``        | flag   | no mask, only a list        |
+ +------------------------------------+--------+-----------------------------+
+ | ``ETHTOOL_A_BITSET_SIZE``          | u32    | number of significant bits  |
+ +------------------------------------+--------+-----------------------------+
+ | ``ETHTOOL_A_BITSET_BITS``          | nested | array of bits               |
+ +-+----------------------------------+--------+-----------------------------+
+ | | ``ETHTOOL_A_BITSET_BITS_BIT+``   | nested | one bit                     |
+ +-+-+--------------------------------+--------+-----------------------------+
+ | | | ``ETHTOOL_A_BITSET_BIT_INDEX`` | u32    | bit index (0 for LSB)       |
+ +-+-+--------------------------------+--------+-----------------------------+
+ | | | ``ETHTOOL_A_BITSET_BIT_NAME``  | string | bit name                    |
+ +-+-+--------------------------------+--------+-----------------------------+
+ | | | ``ETHTOOL_A_BITSET_BIT_VALUE`` | flag   | present if bit is set       |
+ +-+-+--------------------------------+--------+-----------------------------+
+
+Bit size is optional for bit-by-bit form. ``ETHTOOL_A_BITSET_BITS`` nest can
+only contain ``ETHTOOL_A_BITSET_BITS_BIT`` attributes but there can be an
+arbitrary number of them.  A bit may be identified by its index or by its
+name. When used in requests, listed bits are set to 0 or 1 according to
+``ETHTOOL_A_BITSET_BIT_VALUE``, the rest is preserved. A request fails if
+index exceeds kernel bit length or if name is not recognized.
+
+When ``ETHTOOL_A_BITSET_NOMASK`` flag is present, bitset is interpreted as
+a simple bitmap. ``ETHTOOL_A_BITSET_BIT_VALUE`` attributes are not used in
+such case. Such bitset represents a bitmap with listed bits set and the rest
+zero.
+
+In requests, application can use either form. Form used by kernel in reply is
+determined by ``ETHTOOL_FLAG_COMPACT_BITSETS`` flag in flags field of request
+header. Semantics of value and mask depends on the attribute.
+
+
+List of message types
+=====================
+
+All constants identifying message types use ``ETHTOOL_CMD_`` prefix and suffix
+according to message purpose:
+
+  ==============    ======================================
+  ``_GET``          userspace request to retrieve data
+  ``_SET``          userspace request to set data
+  ``_ACT``          userspace request to perform an action
+  ``_GET_REPLY``    kernel reply to a ``GET`` request
+  ``_SET_REPLY``    kernel reply to a ``SET`` request
+  ``_ACT_REPLY``    kernel reply to an ``ACT`` request
+  ``_NTF``          kernel notification
+  ==============    ======================================
+
+Userspace to kernel:
+
+  ===================================== ================================
+  ``ETHTOOL_MSG_STRSET_GET``            get string set
+  ``ETHTOOL_MSG_LINKINFO_GET``          get link settings
+  ``ETHTOOL_MSG_LINKINFO_SET``          set link settings
+  ``ETHTOOL_MSG_LINKMODES_GET``         get link modes info
+  ``ETHTOOL_MSG_LINKMODES_SET``         set link modes info
+  ``ETHTOOL_MSG_LINKSTATE_GET``         get link state
+  ``ETHTOOL_MSG_DEBUG_GET``             get debugging settings
+  ``ETHTOOL_MSG_DEBUG_SET``             set debugging settings
+  ``ETHTOOL_MSG_WOL_GET``               get wake-on-lan settings
+  ``ETHTOOL_MSG_WOL_SET``               set wake-on-lan settings
+  ===================================== ================================
+
+Kernel to userspace:
+
+  ===================================== =================================
+  ``ETHTOOL_MSG_STRSET_GET_REPLY``      string set contents
+  ``ETHTOOL_MSG_LINKINFO_GET_REPLY``    link settings
+  ``ETHTOOL_MSG_LINKINFO_NTF``          link settings notification
+  ``ETHTOOL_MSG_LINKMODES_GET_REPLY``   link modes info
+  ``ETHTOOL_MSG_LINKMODES_NTF``         link modes notification
+  ``ETHTOOL_MSG_LINKSTATE_GET_REPLY``   link state info
+  ``ETHTOOL_MSG_DEBUG_GET_REPLY``       debugging settings
+  ``ETHTOOL_MSG_DEBUG_NTF``             debugging settings notification
+  ``ETHTOOL_MSG_WOL_GET_REPLY``         wake-on-lan settings
+  ``ETHTOOL_MSG_WOL_NTF``               wake-on-lan settings notification
+  ===================================== =================================
+
+``GET`` requests are sent by userspace applications to retrieve device
+information. They usually do not contain any message specific attributes.
+Kernel replies with corresponding "GET_REPLY" message. For most types, ``GET``
+request with ``NLM_F_DUMP`` and no device identification can be used to query
+the information for all devices supporting the request.
+
+If the data can be also modified, corresponding ``SET`` message with the same
+layout as corresponding ``GET_REPLY`` is used to request changes. Only
+attributes where a change is requested are included in such request (also, not
+all attributes may be changed). Replies to most ``SET`` request consist only
+of error code and extack; if kernel provides additional data, it is sent in
+the form of corresponding ``SET_REPLY`` message which can be suppressed by
+setting ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header.
+
+Data modification also triggers sending a ``NTF`` message with a notification.
+These usually bear only a subset of attributes which was affected by the
+change. The same notification is issued if the data is modified using other
+means (mostly ioctl ethtool interface). Unlike notifications from ethtool
+netlink code which are only sent if something actually changed, notifications
+triggered by ioctl interface may be sent even if the request did not actually
+change any data.
+
+``ACT`` messages request kernel (driver) to perform a specific action. If some
+information is reported by kernel (which can be suppressed by setting
+``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header), the reply takes form of
+an ``ACT_REPLY`` message. Performing an action also triggers a notification
+(``NTF`` message).
+
+Later sections describe the format and semantics of these messages.
+
+
+STRSET_GET
+==========
+
+Requests contents of a string set as provided by ioctl commands
+``ETHTOOL_GSSET_INFO`` and ``ETHTOOL_GSTRINGS.`` String sets are not user
+writeable so that the corresponding ``STRSET_SET`` message is only used in
+kernel replies. There are two types of string sets: global (independent of
+a device, e.g. device feature names) and device specific (e.g. device private
+flags).
+
+Request contents:
+
+ +---------------------------------------+--------+------------------------+
+ | ``ETHTOOL_A_STRSET_HEADER``           | nested | request header         |
+ +---------------------------------------+--------+------------------------+

+ +-+-+-+-+-------------------------------+--------+-----------------------+
+ | ``ETHTOOL_A_STRSET_COUNTS_ONLY``      | flag   | return only counts    |
+ +---------------------------------------+--------+-----------------------+
+
+Device identification in request header is optional. Depending on its presence
+a and ``NLM_F_DUMP`` flag, there are three type of ``STRSET_GET`` requests:
+
+ - no ``NLM_F_DUMP,`` no device: get "global" stringsets
+ - no ``NLM_F_DUMP``, with device: get string sets related to the device
+ - ``NLM_F_DUMP``, no device: get device related string sets for all devices
+
+If there is no ``ETHTOOL_A_STRSET_STRINGSETS`` array, all string sets of
+requested type are returned, otherwise only those specified in the request.
+Flag ``ETHTOOL_A_STRSET_COUNTS_ONLY`` tells kernel to only return string
+counts of the sets, not the actual strings.
+
+
+LINKINFO_GET
+============
+
+Requests link settings as provided by ``ETHTOOL_GLINKSETTINGS`` except for
+link modes and autonegotiation related information. The request does not use
+any attributes.
+
+Request contents:
+
+  ====================================  ======  ==========================
+  ``ETHTOOL_A_LINKINFO_HEADER``         nested  request header
+  ====================================  ======  ==========================
+
+Kernel response contents:
+
+  ====================================  ======  ==========================
+  ``ETHTOOL_A_LINKINFO_HEADER``         nested  reply header
+  ``ETHTOOL_A_LINKINFO_PORT``           u8      physical port
+  ``ETHTOOL_A_LINKINFO_PHYADDR``        u8      phy MDIO address

+  ``ETHTOOL_A_LINKINFO_TP_MDIX_CTRL``   u8      MDI(-X) control
+  ``ETHTOOL_A_LINKINFO_TRANSCEIVER``    u8      transceiver
+  ====================================  ======  ==========================
+
+Attributes and their values have the same meaning as matching members of the
+corresponding ioctl structures.
+
+``LINKINFO_GET`` allows dump requests (kernel returns reply message for all
+devices supporting the request).
+
+
+LINKINFO_SET
+============
+
+``LINKINFO_SET`` request allows setting some of the attributes reported by
+``LINKINFO_GET``.
+
+Request contents:
+
+  ====================================  ======  ==========================
+  ``ETHTOOL_A_LINKINFO_HEADER``         nested  request header

+  ``ETHTOOL_A_LINKINFO_TP_MDIX_CTRL``   u8      MDI(-X) control
+  ====================================  ======  ==========================
+
+MDI(-X) status and transceiver cannot be set, request with the corresponding
+attributes is rejected.
+
+
+LINKMODES_GET
+=============
+
+Requests link modes (supported, advertised and peer advertised) and related
+information (autonegotiation status, link speed and duplex) as provided by
+``ETHTOOL_GLINKSETTINGS``. The request does not use any attributes.
+
+Request contents:

+  ``ETHTOOL_A_LINKMODES_DUPLEX``        u8      duplex mode
+  ====================================  ======  ==========================
+
+For ``ETHTOOL_A_LINKMODES_OURS``, value represents advertised modes and mask
+represents supported modes. ``ETHTOOL_A_LINKMODES_PEER`` in the reply is a bit
+list.
+
+``LINKMODES_GET`` allows dump requests (kernel returns reply messages for all
+devices supporting the request).
+
+
+LINKMODES_SET
+=============
+
+Request contents:
+
+  ====================================  ======  ==========================
+  ``ETHTOOL_A_LINKMODES_HEADER``        nested  request header

+  ``ETHTOOL_A_LINKMODES_DUPLEX``        u8      duplex mode
+  ====================================  ======  ==========================
+
+``ETHTOOL_A_LINKMODES_OURS`` bit set allows setting advertised link modes. If
+autonegotiation is on (either set now or kept from before), advertised modes
+are not changed (no ``ETHTOOL_A_LINKMODES_OURS`` attribute) and at least one
+of speed and duplex is specified, kernel adjusts advertised modes to all
+supported modes matching speed, duplex or both (whatever is specified). This
+autoselection is done on ethtool side with ioctl interface, netlink interface
+is supposed to allow requesting changes without knowing what exactly kernel
+supports.
+
+
+LINKSTATE_GET
+=============
+
+Requests link state information. At the moment, only link up/down flag (as
+provided by ``ETHTOOL_GLINK`` ioctl command) is provided but some future
+extensions are planned (e.g. link down reason). This request does not have any
+attributes.
+
+Request contents:

+  ``ETHTOOL_A_LINKSTATE_LINK``          bool    link state (up/down)
+  ====================================  ======  ==========================
+
+For most NIC drivers, the value of ``ETHTOOL_A_LINKSTATE_LINK`` returns
+carrier flag provided by ``netif_carrier_ok()`` but there are drivers which
+define their own handler.
+
+``LINKSTATE_GET`` allows dump requests (kernel returns reply messages for all
+devices supporting the request).
+
+
+DEBUG_GET
+=========
+
+Requests debugging settings of a device. At the moment, only message mask is
+provided.
+
+Request contents:

+  ``ETHTOOL_A_DEBUG_MSGMASK``           bitset  message mask
+  ====================================  ======  ==========================
+
+The message mask (``ETHTOOL_A_DEBUG_MSGMASK``) is equal to message level as
+provided by ``ETHTOOL_GMSGLVL`` and set by ``ETHTOOL_SMSGLVL`` in ioctl
+interface. While it is called message level there for historical reasons, most
+drivers and almost all newer drivers use it as a mask of enabled message
+classes (represented by ``NETIF_MSG_*`` constants); therefore netlink
+interface follows its actual use in practice.
+
+``DEBUG_GET`` allows dump requests (kernel returns reply messages for all
+devices supporting the request).
+
+
+DEBUG_SET
+=========
+
+Set or update debugging settings of a device. At the moment, only message mask
+is supported.
+
+Request contents:
+
+  ====================================  ======  ==========================
+  ``ETHTOOL_A_DEBUG_HEADER``            nested  request header
+  ``ETHTOOL_A_DEBUG_MSGMASK``           bitset  message mask
+  ====================================  ======  ==========================
+
+``ETHTOOL_A_DEBUG_MSGMASK`` bit set allows setting or modifying mask of
+enabled debugging message types for the device.
+
+
+WOL_GET
+=======
+
+Query device wake-on-lan settings. Unlike most "GET" type requests,
+``ETHTOOL_MSG_WOL_GET`` requires (netns) ``CAP_NET_ADMIN`` privileges as it
+(potentially) provides SecureOn(tm) password which is confidential.
+
+Request contents:
+

+  ``ETHTOOL_A_WOL_SOPASS``              binary  SecureOn(tm) password
+  ====================================  ======  ==========================
+
+In reply, ``ETHTOOL_A_WOL_MODES`` mask consists of modes supported by the
+device, value of modes which are enabled. ``ETHTOOL_A_WOL_SOPASS`` is only
+included in reply if ``WAKE_MAGICSECURE`` mode is supported.
+
+
+WOL_SET
+=======
+
+Set or update wake-on-lan settings.
+
+Request contents:
+
+  ====================================  ======  ==========================
+  ``ETHTOOL_A_WOL_HEADER``              nested  request header

-=======================================
-The padata parallel execution mechanism
-=======================================
-
-:Last updated: for 2.6.36
-
-Padata is a mechanism by which the kernel can farm work out to be done in
-parallel on multiple CPUs while retaining the ordering of tasks.  It was
-developed for use with the IPsec code, which needs to be able to perform
-encryption and decryption on large numbers of packets without reordering
-those packets.  The crypto developers made a point of writing padata in a
-sufficiently general fashion that it could be put to other uses as well.
-
-The first step in using padata is to set up a padata_instance structure for
-overall control of how tasks are to be run::
-
-    #include <linux/padata.h>
-
-    struct padata_instance *padata_alloc(const char *name,
-					 const struct cpumask *pcpumask,
-					 const struct cpumask *cbcpumask);
-
-'name' simply identifies the instance.
-
-The pcpumask describes which processors will be used to execute work
-submitted to this instance in parallel. The cbcpumask defines which
-processors are allowed to be used as the serialization callback processor.
-The workqueue wq is where the work will actually be done; it should be
-a multithreaded queue, naturally.
-
-To allocate a padata instance with the cpu_possible_mask for both
-cpumasks this helper function can be used::
-
-    struct padata_instance *padata_alloc_possible(struct workqueue_struct *wq);
-
-Note: Padata maintains two kinds of cpumasks internally. The user supplied
-cpumasks, submitted by padata_alloc/padata_alloc_possible and the 'usable'
-cpumasks. The usable cpumasks are always a subset of active CPUs in the
-user supplied cpumasks; these are the cpumasks padata actually uses. So
-it is legal to supply a cpumask to padata that contains offline CPUs.
-Once an offline CPU in the user supplied cpumask comes online, padata
-is going to use it.
-
-There are functions for enabling and disabling the instance::
-
-    int padata_start(struct padata_instance *pinst);
-    void padata_stop(struct padata_instance *pinst);
-
-These functions are setting or clearing the "PADATA_INIT" flag;
-if that flag is not set, other functions will refuse to work.
-padata_start returns zero on success (flag set) or -EINVAL if the
-padata cpumask contains no active CPU (flag not set).
-padata_stop clears the flag and blocks until the padata instance
-is unused.
-
-The list of CPUs to be used can be adjusted with these functions::
-
-    int padata_set_cpumasks(struct padata_instance *pinst,
-			    cpumask_var_t pcpumask,
-			    cpumask_var_t cbcpumask);
-    int padata_set_cpumask(struct padata_instance *pinst, int cpumask_type,
-			   cpumask_var_t cpumask);
-    int padata_add_cpu(struct padata_instance *pinst, int cpu, int mask);
-    int padata_remove_cpu(struct padata_instance *pinst, int cpu, int mask);
-
-Changing the CPU masks are expensive operations, though, so it should not be
-done with great frequency.
-
-It's possible to change both cpumasks of a padata instance with
-padata_set_cpumasks by specifying the cpumasks for parallel execution (pcpumask)
-and for the serial callback function (cbcpumask). padata_set_cpumask is used to
-change just one of the cpumasks. Here cpumask_type is one of PADATA_CPU_SERIAL,
-PADATA_CPU_PARALLEL and cpumask specifies the new cpumask to use.
-To simply add or remove one CPU from a certain cpumask the functions
-padata_add_cpu/padata_remove_cpu are used. cpu specifies the CPU to add or
-remove and mask is one of PADATA_CPU_SERIAL, PADATA_CPU_PARALLEL.
-
-If a user is interested in padata cpumask changes, he can register to
-the padata cpumask change notifier::
-
-    int padata_register_cpumask_notifier(struct padata_instance *pinst,
-					 struct notifier_block *nblock);
-
-To unregister from that notifier::
-
-    int padata_unregister_cpumask_notifier(struct padata_instance *pinst,
-					   struct notifier_block *nblock);
-
-The padata cpumask change notifier notifies about changes of the usable
-cpumasks, i.e. the subset of active CPUs in the user supplied cpumask.
-
-Padata calls the notifier chain with::
-
-    blocking_notifier_call_chain(&pinst->cpumask_change_notifier,
-				 notification_mask,
-				 &pd_new->cpumask);
-
-Here cpumask_change_notifier is registered notifier, notification_mask
-is one of PADATA_CPU_SERIAL, PADATA_CPU_PARALLEL and cpumask is a pointer
-to a struct padata_cpumask that contains the new cpumask information.
-
-Actually submitting work to the padata instance requires the creation of a
-padata_priv structure::
-
-    struct padata_priv {
-        /* Other stuff here... */
-	void                    (*parallel)(struct padata_priv *padata);
-	void                    (*serial)(struct padata_priv *padata);
-    };
-
-This structure will almost certainly be embedded within some larger
-structure specific to the work to be done.  Most of its fields are private to
-padata, but the structure should be zeroed at initialisation time, and the
-parallel() and serial() functions should be provided.  Those functions will
-be called in the process of getting the work done as we will see
-momentarily.
-
-The submission of work is done with::
-
-    int padata_do_parallel(struct padata_instance *pinst,
-		           struct padata_priv *padata, int cb_cpu);
-
-The pinst and padata structures must be set up as described above; cb_cpu
-specifies which CPU will be used for the final callback when the work is
-done; it must be in the current instance's CPU mask.  The return value from
-padata_do_parallel() is zero on success, indicating that the work is in
-progress. -EBUSY means that somebody, somewhere else is messing with the
-instance's CPU mask, while -EINVAL is a complaint about cb_cpu not being
-in that CPU mask or about a not running instance.
-
-Each task submitted to padata_do_parallel() will, in turn, be passed to
-exactly one call to the above-mentioned parallel() function, on one CPU, so
-true parallelism is achieved by submitting multiple tasks.  parallel() runs with
-software interrupts disabled and thus cannot sleep.  The parallel()
-function gets the padata_priv structure pointer as its lone parameter;
-information about the actual work to be done is probably obtained by using
-container_of() to find the enclosing structure.
-
-Note that parallel() has no return value; the padata subsystem assumes that
-parallel() will take responsibility for the task from this point.  The work
-need not be completed during this call, but, if parallel() leaves work
-outstanding, it should be prepared to be called again with a new job before
-the previous one completes.  When a task does complete, parallel() (or
-whatever function actually finishes the job) should inform padata of the
-fact with a call to::
-
-    void padata_do_serial(struct padata_priv *padata);
-
-At some point in the future, padata_do_serial() will trigger a call to the
-serial() function in the padata_priv structure.  That call will happen on
-the CPU requested in the initial call to padata_do_parallel(); it, too, is
-run with local software interrupts disabled.
-Note that this call may be deferred for a while since the padata code takes
-pains to ensure that tasks are completed in the order in which they were
-submitted.
-
-The one remaining function in the padata API should be called to clean up
-when a padata instance is no longer needed::
-
-    void padata_free(struct padata_instance *pinst);
-
-This function will busy-wait while any remaining tasks are completed, so it
-might be best not to call it while there is work outstanding.

+AMD-TEE driver
+==============
+
+The AMD-TEE driver handles the communication with AMD's TEE environment. The
+TEE environment is provided by AMD Secure Processor.
+
+The AMD Secure Processor (formerly called Platform Security Processor or PSP)
+is a dedicated processor that features ARM TrustZone technology, along with a
+software-based Trusted Execution Environment (TEE) designed to enable
+third-party Trusted Applications. This feature is currently enabled only for
+APUs.
+
+The following picture shows a high level overview of AMD-TEE::

+
+At the lowest level (in x86), the AMD Secure Processor (ASP) driver uses the
+CPU to PSP mailbox regsister to submit commands to the PSP. The format of the
+command buffer is opaque to the ASP driver. It's role is to submit commands to
+the secure processor and return results to AMD-TEE driver. The interface
+between AMD-TEE driver and AMD Secure Processor driver can be found in [6].
+
+The AMD-TEE driver packages the command buffer payload for processing in TEE.
+The command buffer format for the different TEE commands can be found in [7].
+
+The TEE commands supported by AMD-TEE Trusted OS are:
+* TEE_CMD_ID_LOAD_TA          - loads a Trusted Application (TA) binary into
+                                TEE environment.
+* TEE_CMD_ID_UNLOAD_TA        - unloads TA binary from TEE environment.
+* TEE_CMD_ID_OPEN_SESSION     - opens a session with a loaded TA.
+* TEE_CMD_ID_CLOSE_SESSION    - closes session with loaded TA
+* TEE_CMD_ID_INVOKE_CMD       - invokes a command with loaded TA
+* TEE_CMD_ID_MAP_SHARED_MEM   - maps shared memory
+* TEE_CMD_ID_UNMAP_SHARED_MEM - unmaps shared memory
+
+AMD-TEE Trusted OS is the firmware running on AMD Secure Processor.
+
+The AMD-TEE driver registers itself with TEE subsystem and implements the
+following driver function callbacks:
+
+* get_version - returns the driver implementation id and capability.
+* open - sets up the driver context data structure.
+* release - frees up driver resources.
+* open_session - loads the TA binary and opens session with loaded TA.
+* close_session -  closes session with loaded TA and unloads it.
+* invoke_func - invokes a command with loaded TA.
+
+cancel_req driver callback is not supported by AMD-TEE.
+
+The GlobalPlatform TEE Client API [5] can be used by the user space (client) to
+talk to AMD's TEE. AMD's TEE provides a secure environment for loading, opening
+a session, invoking commands and clossing session with TA.

+# December 2016
+#
+# Add AVX512F+VL+BW code path.
+#
+# November 2017
+#
+# Convert AVX512F+VL+BW code path to pure AVX512F, so that it can be
+# executed even on Knights Landing. Trigger for modification was
+# observation that AVX512 code paths can negatively affect overall
+# Skylake-X system performance. Since we are likely to suppress
+# AVX512F capability flag [at least on Skylake-X], conversion serves
+# as kind of "investment protection". Note that next *lake processor,
+# Cannonlake, has AVX512IFMA code path to execute...
+#
+# Numbers are cycles per processed byte with poly1305_blocks alone,
+# measured with rdtsc at fixed clock frequency.

+# impossible to pre-compute multiples of 5 [referred to as s[]/sN in
+# reference implementations], which means that more such operations
+# would have to be performed in inner loop, which in turn makes critical
+# path longer. In other words, even though base 2^44 reduction might

- * Handle caching attributes in page tables (PAT)
+ * Page Attribute Table (PAT) support: handle memory caching attributes in page tables.
  *
  * Authors: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com>
  *          Suresh B Siddha <suresh.b.siddha@intel.com>
  *
  * Loosely based on earlier PAT patchset from Eric Biederman and Andi Kleen.
+ *
+ * Basic principles:
+ *
+ * PAT is a CPU feature supported by all modern x86 CPUs, to allow the firmware and
+ * the kernel to set one of a handful of 'caching type' attributes for physical
+ * memory ranges: uncached, write-combining, write-through, write-protected,
+ * and the most commonly used and default attribute: write-back caching.
+ *
+ * PAT support supercedes and augments MTRR support in a compatible fashion: MTRR is
+ * a hardware interface to enumerate a limited number of physical memory ranges
+ * and set their caching attributes explicitly, programmed into the CPU via MSRs.
+ * Even modern CPUs have MTRRs enabled - but these are typically not touched
+ * by the kernel or by user-space (such as the X server), we rely on PAT for any
+ * additional cache attribute logic.
+ *
+ * PAT doesn't work via explicit memory ranges, but uses page table entries to add
+ * cache attribute information to the mapped memory range: there's 3 bits used,
+ * (_PAGE_PWT, _PAGE_PCD, _PAGE_PAT), with the 8 possible values mapped by the
+ * CPU to actual cache attributes via an MSR loaded into the CPU (MSR_IA32_CR_PAT).
+ *
+ * ( There's a metric ton of finer details, such as compatibility with CPU quirks
+ *   that only support 4 types of PAT entries, and interaction with MTRRs, see
+ *   below for details. )

+ * PIT64B timer may be fed by gclk or pclk. When gclk is used its rate has to
+ * be at least 3 times lower that pclk's rate. pclk rate is fixed, gclk rate
+ * could be changed via clock APIs. The chosen clock (pclk or gclk) could be
+ * divided by the internal PIT64B's divider.
+ *
+ * This function, first tries to use GCLK by requesting the desired rate from
+ * PMC and then using the internal PIT64B prescaler, if any, to reach the
+ * requested rate. If PCLK/GCLK < 3 (condition requested by PIT64B hardware)
+ * then the function falls back on using PCLK as clock source for PIT64B timer
+ * choosing the highest prescaler in case it doesn't locate one to match the
+ * requested frequency.
+ *
+ * Below is presented the PIT64B block in relation with PMC:

+	  any malicious PCI devices from being able to perform DMA until the

+
+	  This option will cause failures with some poorly behaved hardware

 ideally have no use or idea of the global GPIO numberspace that has/was
 used in the inception of the GPIO subsystem.
 
+The numberspace issue is the same as to why irq is moving away from irq
+numbers to IRQ descriptors.
+
+The underlying motivation for this is that the GPIO numberspace has become
+unmanageable: machine board files tend to become full of macros trying to
+establish the numberspace at compile-time, making it hard to add any numbers
+in the middle (such as if you missed a pin on a chip) without the numberspace
+breaking.
+
+Machine descriptions such as device tree or ACPI does not have a concept of the
+Linux GPIO number as those descriptions are external to the Linux kernel
+and treat GPIO lines as abstract entities.
+
+The runtime-assigned GPIO numberspace (what you get if you assign the GPIO
+base as -1 in struct gpio_chip) has also became unpredictable due to factors
+such as probe ordering and the introduction of -EPROBE_DEFER making probe
+ordering of independent GPIO chips essentially unpredictable, as their base
+number will be assigned on a first come first serve basis.
+
+The best way to get out of the problem is to make the global GPIO numbers
+unimportant by simply not using them. GPIO descriptors deal with this.

+ * This drive supports reporting the temperatire of SATA drives. It can be
+ * easily extended to report the temperature of SCSI drives.
+ *
+ * The primary means to read drive temperatures and temperature limits
+ * for ATA drives is the SCT Command Transport feature set as specified in
+ * ATA8-ACS.
+ * It can be used to read the current drive temperature, temperature limits,
+ * and historic minimum and maximum temperatures. The SCT Command Transport
+ * feature set is documented in "AT Attachment 8 - ATA/ATAPI Command Set
+ * (ATA8-ACS)".
+ *
+ * If the SCT Command Transport feature set is not available, drive temperatures
+ * may be readable through SMART attributes. Since SMART attributes are not well
+ * defined, this method is only used as fallback mechanism.
+ *
+ * There are three SMART attributes which may report drive temperatures.
+ * Those are defined as follows (from
+ * http://www.cropel.com/library/smart-attribute-list.aspx).
+ *
+ * 190	Temperature	Temperature, monitored by a sensor somewhere inside
+ *			the drive. Raw value typicaly holds the actual
+ *			temperature (hexadecimal) in its rightmost two digits.

+ *			the drive. Raw value typicaly holds the actual
+ *			temperature (hexadecimal) in its rightmost two digits.
+ *
+ * Wikipedia defines attributes a bit differently.
+ *
+ * 190	Temperature	Value is equal to (100-temp. °C), allowing manufacturer
+ *	Difference or	to set a minimum threshold which corresponds to a
+ *	Airflow		maximum temperature. This also follows the convention of
+ *	Temperature	100 being a best-case value and lower values being
+ *			undesirable. However, some older drives may instead
+ *			report raw Temperature (identical to 0xC2) or
+ *			Temperature minus 50 here.
+ * 194	Temperature or	Indicates the device temperature, if the appropriate
+ *	Temperature	sensor is fitted. Lowest byte of the raw value contains
+ *	Celsius		the exact temperature value (Celsius degrees).
+ * 231	Life Left	Indicates the approximate SSD life left, in terms of
+ *	(SSDs) or	program/erase cycles or available reserved blocks.
+ *	Temperature	A normalized value of 100 represents a new drive, with
+ *			a threshold value at 10 indicating a need for
+ *			replacement. A value of 0 may mean that the drive is
+ *			operating in read-only mode to allow data recovery.
+ *			Previously (pre-2010) occasionally used for Drive
+ *			Temperature (more typically reported at 0xC2).
+ *
+ * Common denominator is that the first raw byte reports the temperature
+ * in degrees C on almost all drives. Some drives may report a fractional
+ * temperature in the second raw byte.
+ *
+ * Known exceptions (from libatasmart):
+ * - SAMSUNG SV0412H and SAMSUNG SV1204H) report the temperature in 10th
+ *   degrees C in the first two raw bytes.
+ * - A few Maxtor drives report an unknown or bad value in attribute 194.
+ * - Certain Apple SSD drives report an unknown value in attribute 190.
+ *   Only certain firmware versions are affected.
+ *
+ * Those exceptions affect older ATA drives and are currently ignored.
+ * Also, the second raw byte (possibly reporting the fractional temperature)
+ * is currently ignored.
+ *
+ * Many drives also report temperature limits in additional SMART data raw
+ * bytes. The format of those is not well defined and varies widely.
+ * The driver does not currently attempt to report those limits.
+ *
+ * According to data in smartmontools, attribute 231 is rarely used to report
+ * drive temperatures. At the same time, several drives report SSD life left
+ * in attribute 231, but do not support temperature sensors. For this reason,
+ * attribute 231 is currently ignored.
+ *
+ * Following above definitions, temperatures are reported as follows.
+ *   If SCT Command Transport is supported, it is used to read the
+ *   temperature and, if available, temperature limits.
+ * - Otherwise, if SMART attribute 194 is supported, it is used to read
+ *   the temperature.
+ * - Otherwise, if SMART attribute 190 is supported, it is used to read
+ *   the temperature.

+ * for, and a single stats can span over multiple HTT stats indication
+ * due to the HTT message size limitation so every HTT ext stats indication
+ * will have tag-length-value stats information elements.
+ * The tag-length header for each HTT stats IND message also includes a
+ * status field, to indicate whether the request for the stat type in
+ * question was fully met, partially met, unable to be met, or invalid
+ * (if the stat type in question is disabled in the target).
+ * A Done bit 1's indicate the end of the of stats info elements.

+ * This contains the logic to handle async discard.
+ *
+ * Async discard manages trimming of free space outside of transaction commit.
+ * Discarding is done by managing the block_groups on a LRU list based on free
+ * space recency.  Two passes are used to first prioritize discarding extents
+ * and then allow for trimming in the bitmap the best opportunity to coalesce.
+ * The block_groups are maintained on multiple lists to allow for multiple
+ * passes with different discard filter requirements.  A delayed work item is
+ * used to manage discarding with timeout determined by a max of the delay
+ * incurred by the iops rate limit, the byte rate limit, and the max delay of
+ * BTRFS_DISCARD_MAX_DELAY.
+ *
+ * Note, this only keeps track of block_groups that are explicitly for data.
+ * Mixed block_groups are not supported.
+ *
+ * The first list is special to manage discarding of fully free block groups.
+ * This is necessary because we issue a final trim for a full free block group
+ * after forgetting it.  When a block group becomes unused, instead of directly
+ * being added to the unused_bgs list, we add it to this first list.  Then
+ * from there, if it becomes fully discarded, we place it onto the unused_bgs
+ * list.
+ *
+ * The in-memory free space cache serves as the backing state for discard.
+ * Consequently this means there is no persistence.  We opt to load all the
+ * block groups in as not discarded, so the mount case degenerates to the
+ * crashing case.
+ *
+ * As the free space cache uses bitmaps, there exists a tradeoff between
+ * ease/efficiency for find_free_extent() and the accuracy of discard state.
+ * Here we opt to let untrimmed regions merge with everything while only letting
+ * trimmed regions merge with other trimmed regions.  This can cause
+ * overtrimming, but the coalescing benefit seems to be worth it.  Additionally,
+ * bitmap state is tracked as a whole.  If we're able to fully trim a bitmap,
+ * the trimmed flag is set on the bitmap.  Otherwise, if an allocation comes in,
+ * this resets the state and we will retry trimming the whole bitmap.  This is a
+ * tradeoff between discard state accuracy and the cost of accounting.

- * the ugly parts come from merging extents from the disk with the in-ram
- * representation.  This gets more complex because of the data=ordered code,
- * where the in-ram extents might be locked pending data=ordered completion.
+/**
+ * btrfs_get_extent - Lookup the first extent overlapping a range in a file.
+ * @inode:	file to search in
+ * @page:	page to read extent data into if the extent is inline
+ * @pg_offset:	offset into @page to copy to
+ * @start:	file offset
+ * @len:	length of range starting at @start
+ *
+ * This returns the first &struct extent_map which overlaps with the given
+ * range, reading it from the B-tree and caching it if necessary. Note that
+ * there may be more extents which overlap the given range after the returned
+ * extent_map.
+ *
+ * If @page is not NULL and the extent is inline, this also reads the extent
+ * data directly into the page and marks the extent up to date in the io_tree.
  *
- * This also copies inline extents directly into the page.
+ * Return: ERR_PTR on error, non-NULL extent_map on success.

+ * struct fscrypt_nokey_name - identifier for directory entry when key is absent
+ *
+ * When userspace lists an encrypted directory without access to the key, the
+ * filesystem must present a unique "no-key name" for each filename that allows
+ * it to find the directory entry again if requested.  Naively, that would just
+ * mean using the ciphertext filenames.  However, since the ciphertext filenames
+ * can contain illegal characters ('\0' and '/'), they must be encoded in some
+ * way.  We use base64.  But that can cause names to exceed NAME_MAX (255
+ * bytes), so we also need to use a strong hash to abbreviate long names.
+ *
+ * The filesystem may also need another kind of hash, the "dirhash", to quickly
+ * find the directory entry.  Since filesystems normally compute the dirhash
+ * over the on-disk filename (i.e. the ciphertext), it's not computable from
+ * no-key names that abbreviate the ciphertext using the strong hash to fit in
+ * NAME_MAX.  It's also not computable if it's a keyed hash taken over the
+ * plaintext (but it may still be available in the on-disk directory entry);
+ * casefolded directories use this type of dirhash.  At least in these cases,
+ * each no-key name must include the name's dirhash too.
+ *
+ * To meet all these requirements, we base64-encode the following
+ * variable-length structure.  It contains the dirhash, or 0's if the filesystem
+ * didn't provide one; up to 149 bytes of the ciphertext name; and for
+ * ciphertexts longer than 149 bytes, also the SHA-256 of the remaining bytes.
+ *
+ * This ensures that each no-key name contains everything needed to find the
+ * directory entry again, contains only legal characters, doesn't exceed
+ * NAME_MAX, is unambiguous unless there's a SHA-256 collision, and that we only
+ * take the performance hit of SHA-256 on very long filenames (which are rare).

- * bytes are shown in this abbreviated form (base64-encoded) rather than as the

- * followed by the second-to-last ciphertext block of the filename.  Due to the
- * use of the CBC-CTS encryption mode, the second-to-last ciphertext block
- * depends on the full plaintext.  (Note that ciphertext stealing causes the
- * last two blocks to appear "flipped".)  This makes accidental collisions very
- * unlikely: just a 1 in 2^128 chance for two filenames to collide even if they
- * share the same filesystem-specific hashes.
- *
- * However, this scheme isn't immune to intentional collisions, which can be
- * created by anyone able to create arbitrary plaintext filenames and view them
- * without the key.  Making the "digest" be a real cryptographic hash like
- * SHA-256 over the full ciphertext would prevent this, although it would be

+ * DOC: Theory of Operation
+ *
+ *
+ * Problem
+ * -------
+ *
+ * Match packet bytes against entries composed of ranged or non-ranged packet
+ * field specifiers, mapping them to arbitrary references. For example:
+ *
+ * ::
+ *
+ *               --- fields --->
+ *      |    [net],[port],[net]... => [reference]
+ *   entries [net],[port],[net]... => [reference]
+ *      |    [net],[port],[net]... => [reference]
+ *      V    ...
+ *
+ * where [net] fields can be IP ranges or netmasks, and [port] fields are port
+ * ranges. Arbitrary packet fields can be matched.
+ *
+ *
+ * Algorithm Overview
+ * ------------------
+ *
+ * This algorithm is loosely inspired by [Ligatti 2010], and fundamentally
+ * relies on the consideration that every contiguous range in a space of b bits
+ * can be converted into b * 2 netmasks, from Theorem 3 in [Rottenstreich 2010],
+ * as also illustrated in Section 9 of [Kogan 2014].
+ *
+ * Classification against a number of entries, that require matching given bits
+ * of a packet field, is performed by grouping those bits in sets of arbitrary
+ * size, and classifying packet bits one group at a time.
+ *
+ * Example:
+ *   to match the source port (16 bits) of a packet, we can divide those 16 bits
+ *   in 4 groups of 4 bits each. Given the entry:
+ *      0000 0001 0101 1001
+ *   and a packet with source port:
+ *      0000 0001 1010 1001
+ *   first and second groups match, but the third doesn't. We conclude that the
+ *   packet doesn't match the given entry.
+ *
+ * Translate the set to a sequence of lookup tables, one per field. Each table
+ * has two dimensions: bit groups to be matched for a single packet field, and
+ * all the possible values of said groups (buckets). Input entries are
+ * represented as one or more rules, depending on the number of composing
+ * netmasks for the given field specifier, and a group match is indicated as a
+ * set bit, with number corresponding to the rule index, in all the buckets
+ * whose value matches the entry for a given group.
+ *
+ * Rules are mapped between fields through an array of x, n pairs, with each
+ * item mapping a matched rule to one or more rules. The position of the pair in
+ * the array indicates the matched rule to be mapped to the next field, x
+ * indicates the first rule index in the next field, and n the amount of
+ * next-field rules the current rule maps to.
+ *
+ * The mapping array for the last field maps to the desired references.
+ *
+ * To match, we perform table lookups using the values of grouped packet bits,
+ * and use a sequence of bitwise operations to progressively evaluate rule
+ * matching.
+ *
+ * A stand-alone, reference implementation, also including notes about possible
+ * future optimisations, is available at:
+ *    https://pipapo.lameexcu.se/
+ *
+ * Insertion
+ * ---------
+ *
+ * - For each packet field:
+ *
+ *   - divide the b packet bits we want to classify into groups of size t,
+ *     obtaining ceil(b / t) groups
+ *
+ *      Example: match on destination IP address, with t = 4: 32 bits, 8 groups
+ *      of 4 bits each
+ *
+ *   - allocate a lookup table with one column ("bucket") for each possible
+ *     value of a group, and with one row for each group
+ *
+ *      Example: 8 groups, 2^4 buckets:
+ *
+ * ::
+ *
+ *                     bucket
+ *      group  0   1   2   3   4   5   6   7   8   9  10  11  12  13  14  15
+ *        0
+ *        1
+ *        2
+ *        3
+ *        4
+ *        5
+ *        6
+ *        7
+ *
+ *   - map the bits we want to classify for the current field, for a given
+ *     entry, to a single rule for non-ranged and netmask set items, and to one
+ *     or multiple rules for ranges. Ranges are expanded to composing netmasks
+ *     by pipapo_expand().
+ *
+ *      Example: 2 entries, 10.0.0.5:1024 and 192.168.1.0-192.168.2.1:2048
+ *      - rule #0: 10.0.0.5
+ *      - rule #1: 192.168.1.0/24
+ *      - rule #2: 192.168.2.0/31
+ *
+ *   - insert references to the rules in the lookup table, selecting buckets
+ *     according to bit values of a rule in the given group. This is done by
+ *     pipapo_insert().
+ *
+ *      Example: given:
+ *      - rule #0: 10.0.0.5 mapping to buckets
+ *        < 0 10  0 0   0 0  0 5 >
+ *      - rule #1: 192.168.1.0/24 mapping to buckets
+ *        < 12 0  10 8  0 1  < 0..15 > < 0..15 > >
+ *      - rule #2: 192.168.2.0/31 mapping to buckets
+ *        < 12 0  10 8  0 2  0 < 0..1 > >
+ *
+ *      these bits are set in the lookup table:
+ *
+ * ::
+ *
+ *                     bucket
+ *      group  0   1   2   3   4   5   6   7   8   9  10  11  12  13  14  15
+ *        0    0                                              1,2
+ *        1   1,2                                      0
+ *        2    0                                      1,2
+ *        3    0                              1,2
+ *        4  0,1,2
+ *        5    0   1   2
+ *        6  0,1,2 1   1   1   1   1   1   1   1   1   1   1   1   1   1   1
+ *        7   1,2 1,2  1   1   1  0,1  1   1   1   1   1   1   1   1   1   1
+ *
+ *   - if this is not the last field in the set, fill a mapping array that maps
+ *     rules from the lookup table to rules belonging to the same entry in
+ *     the next lookup table, done by pipapo_map().
+ *
+ *     Note that as rules map to contiguous ranges of rules, given how netmask
+ *     expansion and insertion is performed, &union nft_pipapo_map_bucket stores
+ *     this information as pairs of first rule index, rule count.
+ *
+ *      Example: 2 entries, 10.0.0.5:1024 and 192.168.1.0-192.168.2.1:2048,
+ *      given lookup table #0 for field 0 (see example above):
+ *
+ * ::
+ *
+ *                     bucket
+ *      group  0   1   2   3   4   5   6   7   8   9  10  11  12  13  14  15
+ *        0    0                                              1,2
+ *        1   1,2                                      0
+ *        2    0                                      1,2
+ *        3    0                              1,2
+ *        4  0,1,2
+ *        5    0   1   2
+ *        6  0,1,2 1   1   1   1   1   1   1   1   1   1   1   1   1   1   1
+ *        7   1,2 1,2  1   1   1  0,1  1   1   1   1   1   1   1   1   1   1
+ *
+ *      and lookup table #1 for field 1 with:
+ *      - rule #0: 1024 mapping to buckets
+ *        < 0  0  4  0 >
+ *      - rule #1: 2048 mapping to buckets
+ *        < 0  0  5  0 >
+ *
+ * ::
+ *
+ *                     bucket
+ *      group  0   1   2   3   4   5   6   7   8   9  10  11  12  13  14  15
+ *        0   0,1
+ *        1   0,1
+ *        2                    0   1
+ *        3   0,1
+ *
+ *      we need to map rules for 10.0.0.5 in lookup table #0 (rule #0) to 1024
+ *      in lookup table #1 (rule #0) and rules for 192.168.1.0-192.168.2.1
+ *      (rules #1, #2) to 2048 in lookup table #2 (rule #1):
+ *
+ * ::
+ *
+ *       rule indices in current field: 0    1    2
+ *       map to rules in next field:    0    1    1
+ *
+ *   - if this is the last field in the set, fill a mapping array that maps
+ *     rules from the last lookup table to element pointers, also done by
+ *     pipapo_map().
+ *
+ *     Note that, in this implementation, we have two elements (start, end) for
+ *     each entry. The pointer to the end element is stored in this array, and
+ *     the pointer to the start element is linked from it.
+ *
+ *      Example: entry 10.0.0.5:1024 has a corresponding &struct nft_pipapo_elem
+ *      pointer, 0x66, and element for 192.168.1.0-192.168.2.1:2048 is at 0x42.
+ *      From the rules of lookup table #1 as mapped above:
+ *
+ * ::
+ *
+ *       rule indices in last field:    0    1
+ *       map to elements:             0x42  0x66
+ *
+ *
+ * Matching
+ * --------
+ *
+ * We use a result bitmap, with the size of a single lookup table bucket, to
+ * represent the matching state that applies at every algorithm step. This is
+ * done by pipapo_lookup().
+ *
+ * - For each packet field:
+ *
+ *   - start with an all-ones result bitmap (res_map in pipapo_lookup())
+ *
+ *   - perform a lookup into the table corresponding to the current field,
+ *     for each group, and at every group, AND the current result bitmap with
+ *     the value from the lookup table bucket
+ *
+ * ::
+ *
+ *      Example: 192.168.1.5 < 12 0  10 8  0 1  0 5 >, with lookup table from
+ *      insertion examples.
+ *      Lookup table buckets are at least 3 bits wide, we'll assume 8 bits for
+ *      convenience in this example. Initial result bitmap is 0xff, the steps
+ *      below show the value of the result bitmap after each group is processed:
+ *
+ *                     bucket
+ *      group  0   1   2   3   4   5   6   7   8   9  10  11  12  13  14  15
+ *        0    0                                              1,2
+ *        result bitmap is now: 0xff & 0x6 [bucket 12] = 0x6
+ *
+ *        1   1,2                                      0
+ *        result bitmap is now: 0x6 & 0x6 [bucket 0] = 0x6
+ *
+ *        2    0                                      1,2
+ *        result bitmap is now: 0x6 & 0x6 [bucket 10] = 0x6
+ *
+ *        3    0                              1,2
+ *        result bitmap is now: 0x6 & 0x6 [bucket 8] = 0x6
+ *
+ *        4  0,1,2
+ *        result bitmap is now: 0x6 & 0x7 [bucket 0] = 0x6
+ *

+ *        result bitmap is now: 0x6 & 0x2 [bucket 1] = 0x2
+ *
+ *        6  0,1,2 1   1   1   1   1   1   1   1   1   1   1   1   1   1   1

+ *        7   1,2 1,2  1   1   1  0,1  1   1   1   1   1   1   1   1   1   1
+ *        final result bitmap for this field is: 0x2 & 0x3 [bucket 5] = 0x2
+ *
+ *   - at the next field, start with a new, all-zeroes result bitmap. For each
+ *     bit set in the previous result bitmap, fill the new result bitmap
+ *     (fill_map in pipapo_lookup()) with the rule indices from the
+ *     corresponding buckets of the mapping field for this field, done by
+ *     pipapo_refill()
+ *
+ *      Example: with mapping table from insertion examples, with the current
+ *      result bitmap from the previous example, 0x02:
+ *
+ * ::
+ *
+ *       rule indices in current field: 0    1    2
+ *       map to rules in next field:    0    1    1
+ *
+ *      the new result bitmap will be 0x02: rule 1 was set, and rule 1 will be
+ *      set.
+ *
+ *      We can now extend this example to cover the second iteration of the step
+ *      above (lookup and AND bitmap): assuming the port field is
+ *      2048 < 0  0  5  0 >, with starting result bitmap 0x2, and lookup table
+ *      for "port" field from pre-computation example:
+ *
+ * ::
+ *
+ *                     bucket
+ *      group  0   1   2   3   4   5   6   7   8   9  10  11  12  13  14  15
+ *        0   0,1
+ *        1   0,1
+ *        2                    0   1
+ *        3   0,1
+ *
+ *       operations are: 0x2 & 0x3 [bucket 0] & 0x3 [bucket 0] & 0x2 [bucket 5]
+ *       & 0x3 [bucket 0], resulting bitmap is 0x2.
+ *
+ *   - if this is the last field in the set, look up the value from the mapping
+ *     array corresponding to the final result bitmap
+ *
+ *      Example: 0x2 resulting bitmap from 192.168.1.5:2048, mapping array for
+ *      last field from insertion example:
+ *
+ * ::
+ *
+ *       rule indices in last field:    0    1
+ *       map to elements:             0x42  0x66
+ *
+ *      the matching element is at 0x42.

+ * net/sched/sch_ets.c         Enhanced Transmission Selection scheduler
+ *
+ * Description
+ * -----------
+ *
+ * The Enhanced Transmission Selection scheduler is a classful queuing
+ * discipline that merges functionality of PRIO and DRR qdiscs in one scheduler.
+ * ETS makes it easy to configure a set of strict and bandwidth-sharing bands to
+ * implement the transmission selection described in 802.1Qaz.
+ *
+ * Although ETS is technically classful, it's not possible to add and remove
+ * classes at will. Instead one specifies number of classes, how many are
+ * PRIO-like and how many DRR-like, and quanta for the latter.
+ *
+ * Algorithm
+ * ---------
+ *
+ * The strict classes, if any, are tried for traffic first: first band 0, if it
+ * has no traffic then band 1, etc.
+ *
+ * When there is no traffic in any of the strict queues, the bandwidth-sharing
+ * ones are tried next. Each band is assigned a deficit counter, initialized to
+ * "quantum" of that band. ETS maintains a list of active bandwidth-sharing
+ * bands whose qdiscs are non-empty. A packet is dequeued from the band at the
+ * head of the list if the packet size is smaller or equal to the deficit
+ * counter. If the counter is too small, it is increased by "quantum" and the
+ * scheduler moves on to the next band in the active list.

+ *
+ * Principles:
+ *   - Packets are classified on flows.
+ *   - This is a Stochastic model (as we use a hash, several flows might
+ *                                 be hashed to the same slot)
+ *   - Each flow has a PIE managed queue.
+ *   - Flows are linked onto two (Round Robin) lists,
+ *     so that new flows have priority on old ones.
+ *   - For a given flow, packets are not reordered.
+ *   - Drops during enqueue only.
+ *   - ECN capability is off by default.
+ *   - ECN threshold (if ECN is enabled) is at 10% by default.
+ *   - Uses timestamps to calculate queue delay by default.

+DESCRIPTION
+===========
+	**bpftool gen skeleton** *FILE*
+		  Generate BPF skeleton C header file for a given *FILE*.
+
+		  BPF skeleton is an alternative interface to existing libbpf
+		  APIs for working with BPF objects. Skeleton code is intended
+		  to significantly shorten and simplify code to load and work
+		  with BPF programs from userspace side. Generated code is
+		  tailored to specific input BPF object *FILE*, reflecting its
+		  structure by listing out available maps, program, variables,
+		  etc. Skeleton eliminates the need to lookup mentioned
+		  components by name. Instead, if skeleton instantiation
+		  succeeds, they are populated in skeleton structure as valid
+		  libbpf types (e.g., struct bpf_map pointer) and can be
+		  passed to existing generic libbpf APIs.
+
+		  In addition to simple and reliable access to maps and
+		  programs, skeleton provides a storage for BPF links (struct
+		  bpf_link) for each BPF program within BPF object. When
+		  requested, supported BPF programs will be automatically
+		  attached and resulting BPF links stored for further use by
+		  user in pre-allocated fields in skeleton struct. For BPF
+		  programs that can't be automatically attached by libbpf,
+		  user can attach them manually, but store resulting BPF link
+		  in per-program link field. All such set up links will be
+		  automatically destroyed on BPF skeleton destruction. This
+		  eliminates the need for users to manage links manually and
+		  rely on libbpf support to detach programs and free up
+		  resources.
+
+		  Another facility provided by BPF skeleton is an interface to
+		  global variables of all supported kinds: mutable, read-only,
+		  as well as extern ones. This interface allows to pre-setup
+		  initial values of variables before BPF object is loaded and
+		  verified by kernel. For non-read-only variables, the same
+		  interface can be used to fetch values of global variables on
+		  userspace side, even if they are modified by BPF code.
+
+		  During skeleton generation, contents of source BPF object
+		  *FILE* is embedded within generated code and is thus not
+		  necessary to keep around. This ensures skeleton and BPF
+		  object file are matching 1-to-1 and always stay in sync.
+		  Generated code is dual-licensed under LGPL-2.1 and
+		  BSD-2-Clause licenses.
+
+		  It is a design goal and guarantee that skeleton interfaces
+		  are interoperable with generic libbpf APIs. User should
+		  always be able to use skeleton API to create and load BPF
+		  object, and later use libbpf APIs to keep working with
+		  specific maps, programs, etc.
+
+		  As part of skeleton, few custom functions are generated.
+		  Each of them is prefixed with object name, derived from
+		  object file name. I.e., if BPF object file name is
+		  **example.o**, BPF object name will be **example**. The
+		  following custom functions are provided in such case:
+
+		  - **example__open** and **example__open_opts**.
+		    These functions are used to instantiate skeleton. It
+		    corresponds to libbpf's **bpf_object__open()** API.
+		    **_opts** variants accepts extra **bpf_object_open_opts**
+		    options.
+
+		  - **example__load**.
+		    This function creates maps, loads and verifies BPF
+		    programs, initializes global data maps. It corresponds to
+		    libppf's **bpf_object__load** API.
+
+		  - **example__open_and_load** combines **example__open** and
+		    **example__load** invocations in one commonly used
+		    operation.
+
+		  - **example__attach** and **example__detach**
+		    This pair of functions allow to attach and detach,
+		    correspondingly, already loaded BPF object. Only BPF
+		    programs of types supported by libbpf for auto-attachment
+		    will be auto-attached and their corresponding BPF links
+		    instantiated. For other BPF programs, user can manually
+		    create a BPF link and assign it to corresponding fields in
+		    skeleton struct. **example__detach** will detach both
+		    links created automatically, as well as those populated by
+		    user manually.
+
+		  - **example__destroy**
+		    Detach and unload BPF programs, free up all the resources
+		    used by skeleton and BPF object.
+
+		  If BPF object has global variables, corresponding structs
+		  with memory layout corresponding to global data data section
+		  layout will be created. Currently supported ones are: *.data*,
+		  *.bss*, *.rodata*, and *.kconfig* structs/data sections.
+		  These data sections/structs can be used to set up initial
+		  values of variables, if set before **example__load**.
+		  Afterwards, if target kernel supports memory-mapped BPF
+		  arrays, same structs can be used to fetch and update
+		  (non-read-only) data from userspace, with same simplicity
+		  as for BPF side.
+
+	**bpftool gen help**
+		  Print short help message.
+
+OPTIONS
+=======
+	-h, --help
+		  Print short generic help message (similar to **bpftool help**).
+
+	-V, --version
+		  Print version number (similar to **bpftool version**).
+
+	-j, --json
+		  Generate JSON output. For commands that cannot produce JSON,
+		  this option has no effect.
+
+	-p, --pretty
+		  Generate human-readable JSON output. Implies **-j**.
+
+	-d, --debug
+		  Print all logs available from libbpf, including debug-level
+		  information.
+
+EXAMPLES
+========
+**$ cat example.c**
+::
+
+  #include <stdbool.h>
+  #include <linux/ptrace.h>
+  #include <linux/bpf.h>
+  #include "bpf_helpers.h"
+
+  const volatile int param1 = 42;
+  bool global_flag = true;
+  struct { int x; } data = {};
+
+  struct {
+  	__uint(type, BPF_MAP_TYPE_HASH);
+  	__uint(max_entries, 128);
+  	__type(key, int);
+  	__type(value, long);
+  } my_map SEC(".maps");
+
+  SEC("raw_tp/sys_enter")
+  int handle_sys_enter(struct pt_regs *ctx)
+  {
+  	static long my_static_var;
+  	if (global_flag)
+  		my_static_var++;
+  	else
+  		data.x += param1;
+  	return 0;
+  }
+
+  SEC("raw_tp/sys_exit")
+  int handle_sys_exit(struct pt_regs *ctx)
+  {
+  	int zero = 0;
+  	bpf_map_lookup_elem(&my_map, &zero);
+  	return 0;
+  }
+
+This is example BPF application with two BPF programs and a mix of BPF maps
+and global variables.

+NAME
+----
+libperf-counting - counting interface
+
+DESCRIPTION
+-----------
+The counting interface provides API to meassure and get count for specific perf events.
+
+The following test tries to explain count on `counting.c` example.
+
+It is by no means complete guide to counting, but shows libperf basic API for counting.
+
+The `counting.c` comes with libbperf package and can be compiled and run like:
+
+[source,bash]
+--
+$ gcc -o counting counting.c -lperf
+$ sudo ./counting
+count 176792, enabled 176944, run 176944
+count 176242, enabled 176242, run 176242
+--
+
+It requires root access, because of the `PERF_COUNT_SW_CPU_CLOCK` event,
+which is available only for root.
+
+The `counting.c` example monitors two events on the current process and displays their count, in a nutshel it:
+
+* creates events
+* adds them to the event list
+* opens and enables events through the event list
+* does some workload
+* disables events
+* reads and displays event counts
+* destroys the event list
+
+The first thing you need to do before using libperf is to call init function:
+
+[source,c]
+--
+  8 static int libperf_print(enum libperf_print_level level,
+  9                          const char *fmt, va_list ap)
+ 10 {
+ 11         return vfprintf(stderr, fmt, ap);
+ 12 }
+
+ 14 int main(int argc, char **argv)
+ 15 {
+ ...
+ 35         libperf_init(libperf_print);
+--
+
+It will setup the library and sets function for debug output from library.
+
+The `libperf_print` callback will receive any message with its debug level,
+defined as:
+
+[source,c]
+--
+enum libperf_print_level {
+        LIBPERF_ERR,
+        LIBPERF_WARN,
+        LIBPERF_INFO,
+        LIBPERF_DEBUG,
+        LIBPERF_DEBUG2,
+        LIBPERF_DEBUG3,
+};
+--
+
+Once the setup is complete we start by defining specific events using the `struct perf_event_attr`.
+
+We create software events for cpu and task:
+
+[source,c]
+--
+ 20         struct perf_event_attr attr1 = {
+ 21                 .type        = PERF_TYPE_SOFTWARE,
+ 22                 .config      = PERF_COUNT_SW_CPU_CLOCK,
+ 23                 .read_format = PERF_FORMAT_TOTAL_TIME_ENABLED|PERF_FORMAT_TOTAL_TIME_RUNNING,
+ 24                 .disabled    = 1,
+ 25         };
+ 26         struct perf_event_attr attr2 = {
+ 27                 .type        = PERF_TYPE_SOFTWARE,
+ 28                 .config      = PERF_COUNT_SW_TASK_CLOCK,
+ 29                 .read_format = PERF_FORMAT_TOTAL_TIME_ENABLED|PERF_FORMAT_TOTAL_TIME_RUNNING,
+ 30                 .disabled    = 1,
+ 31         };
+--
+
+The `read_format` setup tells perf to include timing details together with each count.
+
+Next step is to prepare threads map.
+
+In this case we will monitor current process, so we create threads map with single pid (0):
+
+[source,c]
+--
+ 37         threads = perf_thread_map__new_dummy();
+ 38         if (!threads) {
+ 39                 fprintf(stderr, "failed to create threads\n");
+ 40                 return -1;
+ 41         }
+ 42
+ 43         perf_thread_map__set_pid(threads, 0, 0);
+--
+
+Now we create libperf's event list, which will serve as holder for the events we want:
+
+[source,c]
+--
+ 45         evlist = perf_evlist__new();
+ 46         if (!evlist) {
+ 47                 fprintf(stderr, "failed to create evlist\n");
+ 48                 goto out_threads;
+ 49         }
+--
+
+We create libperf's events for the attributes we defined earlier and add them to the list:
+
+[source,c]
+--
+ 51         evsel = perf_evsel__new(&attr1);
+ 52         if (!evsel) {
+ 53                 fprintf(stderr, "failed to create evsel1\n");
+ 54                 goto out_evlist;
+ 55         }
+ 56
+ 57         perf_evlist__add(evlist, evsel);
+ 58
+ 59         evsel = perf_evsel__new(&attr2);
+ 60         if (!evsel) {
+ 61                 fprintf(stderr, "failed to create evsel2\n");
+ 62                 goto out_evlist;
+ 63         }
+ 64
+ 65         perf_evlist__add(evlist, evsel);
+--
+
+Configure event list with the thread map and open events:
+
+[source,c]
+--
+ 67         perf_evlist__set_maps(evlist, NULL, threads);
+ 68
+ 69         err = perf_evlist__open(evlist);
+ 70         if (err) {
+ 71                 fprintf(stderr, "failed to open evsel\n");
+ 72                 goto out_evlist;
+ 73         }
+--
+
+Both events are created as disabled (note the `disabled = 1` assignment above),
+so we need to enable the whole list explicitely (both events).
+
+From this moment events are counting and we can do our workload.
+
+When we are done we disable the events list.
+
+[source,c]
+--
+ 75         perf_evlist__enable(evlist);
+ 76
+ 77         while (count--);
+ 78
+ 79         perf_evlist__disable(evlist);
+--
+
+Now we need to get the counts from events, following code iterates throught the events list and read counts:
+
+[source,c]
+--
+ 81         perf_evlist__for_each_evsel(evlist, evsel) {
+ 82                 perf_evsel__read(evsel, 0, 0, &counts);
+ 83                 fprintf(stdout, "count %llu, enabled %llu, run %llu\n",
+ 84                         counts.val, counts.ena, counts.run);
+ 85         }
+--
+
+And finaly cleanup.
+
+We close the whole events list (both events) and remove it together with the threads map:
+
+[source,c]
+--
+ 87         perf_evlist__close(evlist);
+ 88
+ 89 out_evlist:
+ 90         perf_evlist__delete(evlist);
+ 91 out_threads:
+ 92         perf_thread_map__put(threads);
+ 93         return err;
+ 94 }

+libperf-sampling - sampling interface
+
+
+DESCRIPTION
+-----------
+The sampling interface provides API to meassure and get count for specific perf events.
+
+The following test tries to explain count on `sampling.c` example.
+
+It is by no means complete guide to sampling, but shows libperf basic API for sampling.

+cpu   0, pid   4465, tid   4470, ip         7f84fe0ebebf, period             17655175
+...
+--
+
+It requires root access, because it uses hardware cycles event.
+
+The `sampling.c` example profiles/samples all CPUs with hardware cycles, in a nutshel it:
+
+- creates events
+- adds them to the event list
+- opens and enables events through the event list
+- sleeps for 3 seconds
+- disables events
+- reads and displays recorded samples
+- destroys the event list
+
+The first thing you need to do before using libperf is to call init function:
+
+[source,c]
+--
+ 12 static int libperf_print(enum libperf_print_level level,
+ 13                          const char *fmt, va_list ap)
+ 14 {
+ 15         return vfprintf(stderr, fmt, ap);
+ 16 }
+
+ 23 int main(int argc, char **argv)
+ 24 {
+ ...
+ 40         libperf_init(libperf_print);
+--
+
+It will setup the library and sets function for debug output from library.
+
+The `libperf_print` callback will receive any message with its debug level,
+defined as:
+
+[source,c]
+--
+enum libperf_print_level {
+        LIBPERF_ERR,
+        LIBPERF_WARN,
+        LIBPERF_INFO,
+        LIBPERF_DEBUG,
+        LIBPERF_DEBUG2,
+        LIBPERF_DEBUG3,
+};
+--
+
+Once the setup is complete we start by defining cycles event using the `struct perf_event_attr`:
+
+[source,c]
+--
+ 29         struct perf_event_attr attr = {
+ 30                 .type        = PERF_TYPE_HARDWARE,
+ 31                 .config      = PERF_COUNT_HW_CPU_CYCLES,
+ 32                 .disabled    = 1,
+ 33                 .freq        = 1,
+ 34                 .sample_freq = 10,
+ 35                 .sample_type = PERF_SAMPLE_IP|PERF_SAMPLE_TID|PERF_SAMPLE_CPU|PERF_SAMPLE_PERIOD,
+ 36         };
+--
+
+Next step is to prepare cpus map.
+
+In this case we will monitor all the available CPUs:
+
+[source,c]
+--
+ 42         cpus = perf_cpu_map__new(NULL);
+ 43         if (!cpus) {
+ 44                 fprintf(stderr, "failed to create cpus\n");
+ 45                 return -1;
+ 46         }
+--
+
+Now we create libperf's event list, which will serve as holder for the cycles event:
+
+[source,c]
+--
+ 48         evlist = perf_evlist__new();
+ 49         if (!evlist) {
+ 50                 fprintf(stderr, "failed to create evlist\n");
+ 51                 goto out_cpus;
+ 52         }
+--
+
+We create libperf's event for the cycles attribute we defined earlier and add it to the list:
+
+[source,c]
+--
+ 54         evsel = perf_evsel__new(&attr);
+ 55         if (!evsel) {
+ 56                 fprintf(stderr, "failed to create cycles\n");
+ 57                 goto out_cpus;
+ 58         }
+ 59
+ 60         perf_evlist__add(evlist, evsel);
+--
+
+Configure event list with the cpus map and open event:
+
+[source,c]
+--
+ 62         perf_evlist__set_maps(evlist, cpus, NULL);
+ 63
+ 64         err = perf_evlist__open(evlist);
+ 65         if (err) {
+ 66                 fprintf(stderr, "failed to open evlist\n");
+ 67                 goto out_evlist;
+ 68         }
+--
+
+Once the events list is open, we can create memory maps AKA perf ring buffers:
+
+[source,c]
+--
+ 70         err = perf_evlist__mmap(evlist, 4);
+ 71         if (err) {
+ 72                 fprintf(stderr, "failed to mmap evlist\n");
+ 73                 goto out_evlist;
+ 74         }
+--
+
+The event is created as disabled (note the `disabled = 1` assignment above),
+so we need to enable the events list explicitely.
+
+From this moment the cycles event is sampling.
+
+We will sleep for 3 seconds while the ring buffers get data from all CPUs, then we disable the events list.
+
+[source,c]
+--
+ 76         perf_evlist__enable(evlist);
+ 77         sleep(3);
+ 78         perf_evlist__disable(evlist);
+--
+
+Following code walks through the ring buffers and reads stored events/samples:
+
+[source,c]
+--
+ 80         perf_evlist__for_each_mmap(evlist, map, false) {
+ 81                 if (perf_mmap__read_init(map) < 0)
+ 82                         continue;
+ 83
+ 84                 while ((event = perf_mmap__read_event(map)) != NULL) {
+
+                            /* process event */
+
+108                         perf_mmap__consume(map);
+109                 }
+110                 perf_mmap__read_done(map);
+111         }
+
+--
+
+Each sample needs to get parsed:
+
+[source,c]
+--
+ 85                         int cpu, pid, tid;
+ 86                         __u64 ip, period, *array;
+ 87                         union u64_swap u;
+ 88
+ 89                         array = event->sample.array;
+ 90
+ 91                         ip = *array;
+ 92                         array++;
+ 93
+ 94                         u.val64 = *array;
+ 95                         pid = u.val32[0];

+101                         array++;
+102
+103                         period = *array;
+104
+105                         fprintf(stdout, "cpu %3d, pid %6d, tid %6d, ip %20llx, period %20llu\n",
+106                                 cpu, pid, tid, ip, period);
+--
+
+And finaly cleanup.
+
+We close the whole events list (both events) and remove it together with the threads map:
+
+[source,c]
+--
+113 out_evlist:
+114         perf_evlist__delete(evlist);
+115 out_cpus:
+116         perf_cpu_map__put(cpus);

+DESCRIPTION
+-----------
+The libperf library provides an API to access the linux kernel perf
+events subsystem.
+
+Following objects are key to the libperf interface:
+
+[horizontal]
+
+struct perf_cpu_map:: Provides a cpu list abstraction.
+
+struct perf_thread_map:: Provides a thread list abstraction.
+
+struct perf_evsel:: Provides an abstraction for single a perf event.
+
+struct perf_evlist:: Gathers several struct perf_evsel object and performs functions on all of them.
+
+struct perf_mmap:: Provides an abstraction for accessing perf ring buffer.
+
+The exported API functions bind these objects together.

-libperf tutorial
-================
-
-Compile and install libperf from kernel sources
-===============================================
-.. code-block:: bash
-
-  git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
-  cd linux/tools/perf/lib
-  make
-  sudo make install prefix=/usr
-
-Libperf object
-==============
-The libperf library provides several high level objects:
-
-struct perf_cpu_map
-  Provides a cpu list abstraction.
-
-struct perf_thread_map
-  Provides a thread list abstraction.
-
-struct perf_evsel
-  Provides an abstraction for single a perf event.
-
-struct perf_evlist
-  Gathers several struct perf_evsel object and performs functions on all of them.
-
-The exported API binds these objects together,
-for full reference see the libperf.7 man page.
-
-Examples
-========
-Examples aim to explain libperf functionality on simple use cases.
-They are based in on a checked out linux kernel git tree:
-
-.. code-block:: bash
-
-  $ cd tools/perf/lib/Documentation/tutorial/
-  $ ls -d  ex-*
-  ex-1-compile  ex-2-evsel-stat  ex-3-evlist-stat
-
-ex-1-compile example
-====================
-This example shows the basic usage of *struct perf_cpu_map*,
-how to create it and display its cpus:
-
-.. code-block:: bash
-
-  $ cd ex-1-compile/
-  $ make
-  gcc -o test test.c -lperf
-  $ ./test
-  0 1 2 3 4 5 6 7
-
-
-The full code listing is here:
-
-.. code-block:: c
-
-   1 #include <perf/cpumap.h>
-   2
-   3 int main(int argc, char **Argv)
-   4 {
-   5         struct perf_cpu_map *cpus;
-   6         int cpu, tmp;
-   7
-   8         cpus = perf_cpu_map__new(NULL);
-   9
-  10         perf_cpu_map__for_each_cpu(cpu, tmp, cpus)
-  11                 fprintf(stdout, "%d ", cpu);
-  12
-  13         fprintf(stdout, "\n");
-  14
-  15         perf_cpu_map__put(cpus);
-  16         return 0;
-  17 }
-
-
-First you need to include the proper header to have *struct perf_cpumap*
-declaration and functions:
-
-.. code-block:: c
-
-   1 #include <perf/cpumap.h>
-
-
-The *struct perf_cpumap* object is created by *perf_cpu_map__new* call.
-The *NULL* argument asks it to populate the object with the current online CPUs list:
-
-.. code-block:: c
-
-   8         cpus = perf_cpu_map__new(NULL);
-
-This is paired with a *perf_cpu_map__put*, that drops its reference at the end, possibly deleting it.
-
-.. code-block:: c
-
-  15         perf_cpu_map__put(cpus);
-
-The iteration through the *struct perf_cpumap* CPUs is done using the *perf_cpu_map__for_each_cpu*
-macro which requires 3 arguments:
-
-- cpu  - the cpu numer
-- tmp  - iteration helper variable
-- cpus - the *struct perf_cpumap* object
-
-.. code-block:: c
-
-  10         perf_cpu_map__for_each_cpu(cpu, tmp, cpus)
-  11                 fprintf(stdout, "%d ", cpu);
-

+# This is a template for ETS Qdisc test.
+#
+# This test sends from H1 several traffic streams with 802.1p-tagged packets.
+# The tags are used at $swp1 to prioritize the traffic. Each stream is then
+# queued at a different ETS band according to the assigned priority. After
+# runnig for a while, counters at H2 are consulted to determine whether the
+# traffic scheduling was according to the ETS configuration.
+#
+# This template is supposed to be embedded by a test driver, which implements
+# statistics collection, any HW-specific stuff, and prominently configures the
+# system to assure that there is overcommitment at $swp2. That is necessary so
+# that the ETS traffic selection algorithm kicks in and has to schedule some
+# traffic at the expense of other.
+#
+# A driver for veth-based testing is in sch_ets.sh, an example of a driver for
+# an offloaded data path is in selftests/drivers/net/mlxsw/sch_ets.sh.
