  * Queued spinlock
  *

+ * ticket-lock.h and only come looking here when you've considered all the
+ * constraints below and can show your hardware does actually perform better
+ * with qspinlock.
+ *
+ * qspinlock relies on atomic_*_release()/atomic_*_acquire() to be RCsc (or no
+ * weaker than RCtso if you're power), where regular code only expects atomic_t
+ * to be RCpc.
+ *
+ * qspinlock relies on a far greater (compared to asm-generic/spinlock.h) set
+ * of atomic operations to behave well together, please audit them carefully to
+ * ensure they all have forward progress. Many atomic operations may default to
+ * cmpxchg() loops which will not have good forward progress properties on
+ * LL/SC architectures.
+ *
+ * One notable example is atomic_fetch_or_acquire(), which x86 cannot (cheaply)
+ * do. Carefully read the patches that introduced
+ * queued_fetch_set_pending_acquire().
+ *
+ * qspinlock also heavily relies on mixed size atomic operations, in specific
+ * it requires architectures to have xchg16; something which many LL/SC
+ * architectures need to implement as a 32bit and+or in order to satisfy the
+ * forward progress guarantees mentioned above.

+ * MM IOMMU supports 16GB dma address. We separate it to four ranges:
+ * 0 ~ 4G; 4G ~ 8G; 8G ~ 12G; 12G ~ 16G, we could adjust these masters
+ * locate in anyone region. BUT:
+ * a) Make sure all the ports inside a larb are in one range.
+ * b) The iova of any master can NOT cross the 4G/8G/12G boundary.
+ *
+ * This is the suggested mapping in this SoC:
+ *
+ * modules    dma-address-region	larbs-ports
+ * disp         0 ~ 4G                  larb0/1/2/3
+ * vcodec      4G ~ 8G                  larb19/20/21/22/23/24
+ * cam/mdp     8G ~ 12G                 the other larbs.
+ * N/A         12G ~ 16G
+ * CCU0   0x24000_0000 ~ 0x243ff_ffff   larb18: port 0/1
+ * CCU1   0x24400_0000 ~ 0x247ff_ffff   larb18: port 2/3
+ *
+ * This SoC have two IOMMU HWs, this is the detailed connected information:
+ * iommu-vdo: larb0/2/5/7/9/10/11/13/17/19/21/24/25/28

+/**
+ * DOC: DEVICE_LIFESPAN
+ *
+ * The registering driver is the entity that allocates memory for the
+ * auxiliary_device and registers it on the auxiliary bus.  It is important to
+ * note that, as opposed to the platform bus, the registering driver is wholly
+ * responsible for the management of the memory used for the device object.
+ *
+ * To be clear the memory for the auxiliary_device is freed in the release()
+ * callback defined by the registering driver.  The registering driver should
+ * only call auxiliary_device_delete() and then auxiliary_device_uninit() when
+ * it is done with the device.  The release() function is then automatically
+ * called if and when other code releases their reference to the devices.
+ *
+ * A parent object, defined in the shared header file, contains the
+ * auxiliary_device.  It also contains a pointer to the shared object(s), which
+ * also is defined in the shared header.  Both the parent object and the shared
+ * object(s) are allocated by the registering driver.  This layout allows the
+ * auxiliary_driver's registering module to perform a container_of() call to go
+ * from the pointer to the auxiliary_device, that is passed during the call to
+ * the auxiliary_driver's probe function, up to the parent object, and then
+ * have access to the shared object(s).
+ *
+ * The memory for the shared object(s) must have a lifespan equal to, or
+ * greater than, the lifespan of the memory for the auxiliary_device.  The
+ * auxiliary_driver should only consider that the shared object is valid as
+ * long as the auxiliary_device is still registered on the auxiliary bus.  It
+ * is up to the registering driver to manage (e.g. free or keep available) the
+ * memory for the shared object beyond the life of the auxiliary_device.
+ *
+ * The registering driver must unregister all auxiliary devices before its own
+ * driver.remove() is completed.  An easy way to ensure this is to use the
+ * devm_add_action_or_reset() call to register a function against the parent
+ * device which unregisters the auxiliary device object(s).
+ *
+ * Finally, any operations which operate on the auxiliary devices must continue
+ * to function (if only to return an error) after the registering driver
+ * unregisters the auxiliary device.
+ */

+/**
+ * struct auxiliary_device - auxiliary device object.
+ * @dev: Device,
+ *       The release and parent fields of the device structure must be filled
+ *       in
+ * @name: Match name found by the auxiliary device driver,
+ * @id: unique identitier if multiple devices of the same name are exported,
+ *
+ * An auxiliary_device represents a part of its parent device's functionality.
+ * It is given a name that, combined with the registering drivers
+ * KBUILD_MODNAME, creates a match_name that is used for driver binding, and an
+ * id that combined with the match_name provide a unique name to register with
+ * the bus subsystem.  For example, a driver registering an auxiliary device is
+ * named 'foo_mod.ko' and the subdevice is named 'foo_dev'.  The match name is
+ * therefore 'foo_mod.foo_dev'.
+ *
+ * Registering an auxiliary_device is a three-step process.
+ *
+ * First, a 'struct auxiliary_device' needs to be defined or allocated for each
+ * sub-device desired.  The name, id, dev.release, and dev.parent fields of
+ * this structure must be filled in as follows.
+ *
+ * The 'name' field is to be given a name that is recognized by the auxiliary
+ * driver.  If two auxiliary_devices with the same match_name, eg
+ * "foo_mod.foo_dev", are registered onto the bus, they must have unique id
+ * values (e.g. "x" and "y") so that the registered devices names are
+ * "foo_mod.foo_dev.x" and "foo_mod.foo_dev.y".  If match_name + id are not
+ * unique, then the device_add fails and generates an error message.
+ *
+ * The auxiliary_device.dev.type.release or auxiliary_device.dev.release must
+ * be populated with a non-NULL pointer to successfully register the
+ * auxiliary_device.  This release call is where resources associated with the
+ * auxiliary device must be free'ed.  Because once the device is placed on the
+ * bus the parent driver can not tell what other code may have a reference to
+ * this data.
+ *
+ * The auxiliary_device.dev.parent should be set.  Typically to the registering
+ * drivers device.
+ *
+ * Second, call auxiliary_device_init(), which checks several aspects of the
+ * auxiliary_device struct and performs a device_initialize().  After this step
+ * completes, any error state must have a call to auxiliary_device_uninit() in
+ * its resolution path.
+ *
+ * The third and final step in registering an auxiliary_device is to perform a
+ * call to auxiliary_device_add(), which sets the name of the device and adds
+ * the device to the bus.
+ *
+ * .. code-block:: c
+ *
+ *      #define MY_DEVICE_NAME "foo_dev"
+ *
+ *      ...
+ *
+ *	struct auxiliary_device *my_aux_dev = my_aux_dev_alloc(xxx);
+ *
+ *	// Step 1:
+ *	my_aux_dev->name = MY_DEVICE_NAME;
+ *	my_aux_dev->id = my_unique_id_alloc(xxx);
+ *	my_aux_dev->dev.release = my_aux_dev_release;
+ *	my_aux_dev->dev.parent = my_dev;
+ *
+ *	// Step 2:
+ *	if (auxiliary_device_init(my_aux_dev))
+ *		goto fail;
+ *
+ *	// Step 3:
+ *	if (auxiliary_device_add(my_aux_dev)) {
+ *		auxiliary_device_uninit(my_aux_dev);
+ *		goto fail;
+ *	}
+ *
+ *	...
+ *
+ *
+ * Unregistering an auxiliary_device is a two-step process to mirror the
+ * register process.  First call auxiliary_device_delete(), then call
+ * auxiliary_device_uninit().
+ *
+ * .. code-block:: c

+/**
+ * struct comedi_subdevice - Working data for a COMEDI subdevice
+ * @device: COMEDI device to which this subdevice belongs.  (Initialized by
+ *	comedi_alloc_subdevices().)
+ * @index: Index of this subdevice within device's array of subdevices.
+ *	(Initialized by comedi_alloc_subdevices().)
+ * @type: Type of subdevice from &enum comedi_subdevice_type.  (Initialized by
+ *	the low-level driver.)
+ * @n_chan: Number of channels the subdevice supports.  (Initialized by the
+ *	low-level driver.)
+ * @subdev_flags: Various "SDF" flags indicating aspects of the subdevice to
+ *	the COMEDI core and user application.  (Initialized by the low-level
+ *	driver.)
+ * @len_chanlist: Maximum length of a channel list if the subdevice supports
+ *	asynchronous acquisition commands.  (Optionally initialized by the
+ *	low-level driver, or changed from 0 to 1 during post-configuration.)
+ * @private: Private data pointer which is either set by the low-level driver
+ *	itself, or by a call to comedi_alloc_spriv() which allocates storage.
+ *	In the latter case, the storage is automatically freed after the
+ *	low-level driver's "detach" handler is called for the device.
+ *	(Initialized by the low-level driver.)
+ * @async: Pointer to &struct comedi_async id the subdevice supports
+ *	asynchronous acquisition commands.  (Allocated and initialized during
+ *	post-configuration if needed.)
+ * @lock: Pointer to a file object that performed a %COMEDI_LOCK ioctl on the
+ *	subdevice.  (Initially NULL.)
+ * @busy: Pointer to a file object that is performing an asynchronous
+ *	acquisition command on the subdevice.  (Initially NULL.)
+ * @runflags: Internal flags for use by COMEDI core, mostly indicating whether
+ *	an asynchronous acquisition command is running.
+ * @spin_lock: Generic spin-lock for use by the COMEDI core and the low-level
+ *	driver.  (Initialized by comedi_alloc_subdevices().)
+ * @io_bits: Bit-mask indicating the channel directions for a DIO subdevice
+ *	with no more than 32 channels.  A '1' at a bit position indicates the
+ *	corresponding channel is configured as an output.  (Initialized by the
+ *	low-level driver for a DIO subdevice.  Forced to all-outputs during
+ *	post-configuration for a digital output subdevice.)
+ * @maxdata: If non-zero, this is the maximum raw data value of each channel.
+ *	If zero, the maximum data value is channel-specific.  (Initialized by
+ *	the low-level driver.)
+ * @maxdata_list: If the maximum data value is channel-specific, this points
+ *	to an array of maximum data values indexed by channel index.
+ *	(Initialized by the low-level driver.)
+ * @range_table: If non-NULL, this points to a COMEDI range table for the
+ *	subdevice.  If NULL, the range table is channel-specific.  (Initialized
+ *	by the low-level driver, will be set to an "invalid" range table during
+ *	post-configuration if @range_table and @range_table_list are both
+ *	NULL.)
+ * @range_table_list: If the COMEDI range table is channel-specific, this
+ *	points to an array of pointers to COMEDI range tables indexed by
+ *	channel number.  (Initialized by the low-level driver.)
+ * @chanlist: Not used.
+ * @insn_read: Optional pointer to a handler for the %INSN_READ instruction.
+ *	(Initialized by the low-level driver, or set to a default handler
+ *	during post-configuration.)
+ * @insn_write: Optional pointer to a handler for the %INSN_WRITE instruction.
+ *	(Initialized by the low-level driver, or set to a default handler
+ *	during post-configuration.)
+ * @insn_bits: Optional pointer to a handler for the %INSN_BITS instruction
+ *	for a digital input, digital output or digital input/output subdevice.
+ *	(Initialized by the low-level driver, or set to a default handler
+ *	during post-configuration.)
+ * @insn_config: Optional pointer to a handler for the %INSN_CONFIG
+ *	instruction.  (Initialized by the low-level driver, or set to a default
+ *	handler during post-configuration.)
+ * @do_cmd: If the subdevice supports asynchronous acquisition commands, this
+ *	points to a handler to set it up in hardware.  (Initialized by the
+ *	low-level driver.)
+ * @do_cmdtest: If the subdevice supports asynchronous acquisition commands,
+ *	this points to a handler used to check and possibly tweak a prospective
+ *	acquisition command without setting it up in hardware.  (Initialized by
+ *	the low-level driver.)
+ * @poll: If the subdevice supports asynchronous acquisition commands, this
+ *	is an optional pointer to a handler for the %COMEDI_POLL ioctl which
+ *	instructs the low-level driver to synchronize buffers.  (Initialized by
+ *	the low-level driver if needed.)
+ * @cancel: If the subdevice supports asynchronous acquisition commands, this
+ *	points to a handler used to terminate a running command.  (Initialized
+ *	by the low-level driver.)
+ * @buf_change: If the subdevice supports asynchronous acquisition commands,
+ *	this is an optional pointer to a handler that is called when the data
+ *	buffer for handling asynchronous commands is allocated or reallocated.
+ *	(Initialized by the low-level driver if needed.)
+ * @munge: If the subdevice supports asynchronous acquisition commands and
+ *	uses DMA to transfer data from the hardware to the acquisition buffer,
+ *	this points to a function used to "munge" the data values from the
+ *	hardware into the format expected by COMEDI.  (Initialized by the
+ *	low-level driver if needed.)
+ * @async_dma_dir: If the subdevice supports asynchronous acquisition commands
+ *	and uses DMA to transfer data from the hardware to the acquisition
+ *	buffer, this sets the DMA direction for the buffer. (initialized to
+ *	%DMA_NONE by comedi_alloc_subdevices() and changed by the low-level
+ *	driver if necessary.)
+ * @state: Handy bit-mask indicating the output states for a DIO or digital
+ *	output subdevice with no more than 32 channels. (Initialized by the
+ *	low-level driver.)
+ * @class_dev: If the subdevice supports asynchronous acquisition commands,
+ *	this points to a sysfs comediX_subdY device where X is the minor device
+ *	number of the COMEDI device and Y is the subdevice number.  The minor
+ *	device number for the sysfs device is allocated dynamically in the
+ *	range 48 to 255.  This is used to allow the COMEDI device to be opened
+ *	with a different default read or write subdevice.  (Allocated during
+ *	post-configuration if needed.)
+ * @minor: If @class_dev is set, this is its dynamically allocated minor
+ *	device number.  (Set during post-configuration if necessary.)
+ * @readback: Optional pointer to memory allocated by
+ *	comedi_alloc_subdev_readback() used to hold the values written to
+ *	analog output channels so they can be read back.  The storage is
+ *	automatically freed after the low-level driver's "detach" handler is
+ *	called for the device.  (Initialized by the low-level driver.)
+ *
+ * This is the main control structure for a COMEDI subdevice.  If the subdevice
+ * supports asynchronous acquisition commands, additional information is stored
+ * in the &struct comedi_async pointed to by @async.
+ *
+ * Most of the subdevice is initialized by the low-level driver's "attach" or
+ * "auto_attach" handlers but parts of it are initialized by
+ * comedi_alloc_subdevices(), and other parts are initialized during
+ * post-configuration on return from that handler.
+ *
+ * A low-level driver that sets @insn_bits for a digital input, digital output,
+ * or DIO subdevice may leave @insn_read and @insn_write uninitialized, in
+ * which case they will be set to a default handler during post-configuration
+ * that uses @insn_bits to emulate the %INSN_READ and %INSN_WRITE instructions.

+ *   Buf_Write_Count <= Buf_Write_Alloc_Count <=
+ *   (Buf_Read_Count + prealloc_bufsz)
+ *
+ * (Those aren't the actual members, apart from prealloc_bufsz.) When the
+ * buffer is reset, those _Count values start at 0 and only increase in value,
+ * maintaining the above inequalities until the next time the buffer is
+ * reset.  The buffer is divided into the following regions by the inequalities:
+ *
+ *   [0, Buf_Read_Count):
+ *     old region no longer accessible
+ *
+ *   [Buf_Read_Count, Buf_Read_Alloc_Count):
+ *     filled and munged region allocated for reading but not yet read
+ *
+ *   [Buf_Read_Alloc_Count, Munge_Count):
+ *     filled and munged region not yet allocated for reading
+ *
+ *   [Munge_Count, Buf_Write_Count):
+ *     filled region not yet munged

+ *     unfilled region not yet allocated for writing
+ *
+ *   [Buf_Read_Count + prealloc_bufsz, infinity):
+ *     unfilled region not yet accessible
+ *
+ * Data needs to be written into the buffer before it can be read out,
+ * and may need to be converted (or "munged") between the two
+ * operations.  Extra unfilled buffer space may need to allocated for
+ * writing (advancing Buf_Write_Alloc_Count) before new data is written.
+ * After writing new data, the newly filled space needs to be released
+ * (advancing Buf_Write_Count).  This also results in the new data being
+ * "munged" (advancing Munge_Count).  Before data is read out of the
+ * buffer, extra space may need to be allocated for reading (advancing
+ * Buf_Read_Alloc_Count).  After the data has been read out, the space
+ * needs to be released (advancing Buf_Read_Count).
+ *
+ * The actual members, buf_read_count, buf_read_alloc_count,
+ * munge_count, buf_write_count, and buf_write_alloc_count take the
+ * value of the corresponding capitalized _Count values modulo 2^32
+ * (UINT_MAX+1).  Subtracting a "higher" _count value from a "lower"
+ * _count value gives the same answer as subtracting a "higher" _Count
+ * value from a lower _Count value because prealloc_bufsz < UINT_MAX+1.
+ * The modulo operation is done implicitly.
+ *
+ * The buf_read_ptr, munge_ptr, and buf_write_ptr members take the value
+ * of the corresponding capitalized _Count values modulo prealloc_bufsz.
+ * These correspond to byte indices in the physical buffer.  The modulo

-/**
- * DOC: overview
- *
- * Calling dma-buf's vmap operation returns a pointer to the buffer's memory.
- * Depending on the location of the buffer, users may have to access it with
- * I/O operations or memory load/store operations. For example, copying to
- * system memory could be done with memcpy(), copying to I/O memory would be
- * done with memcpy_toio().
- *
- * .. code-block:: c
- *
- *	void *vaddr = ...; // pointer to system memory
- *	memcpy(vaddr, src, len);
- *
- *	void *vaddr_iomem = ...; // pointer to I/O memory
- *	memcpy_toio(vaddr, _iomem, src, len);
- *
- * When using dma-buf's vmap operation, the returned pointer is encoded as
- * :c:type:`struct dma_buf_map <dma_buf_map>`.
- * :c:type:`struct dma_buf_map <dma_buf_map>` stores the buffer's address in
- * system or I/O memory and a flag that signals the required method of
- * accessing the buffer. Use the returned instance and the helper functions
- * to access the buffer's memory in the correct way.
- *
- * The type :c:type:`struct dma_buf_map <dma_buf_map>` and its helpers are
- * actually independent from the dma-buf infrastructure. When sharing buffers
- * among devices, drivers have to know the location of the memory to access
- * the buffers in a safe way. :c:type:`struct dma_buf_map <dma_buf_map>`
- * solves this problem for dma-buf and its users. If other drivers or
- * sub-systems require similar functionality, the type could be generalized
- * and moved to a more prominent header file.
- *
- * Open-coding access to :c:type:`struct dma_buf_map <dma_buf_map>` is
- * considered bad style. Rather then accessing its fields directly, use one
- * of the provided helper functions, or implement your own. For example,
- * instances of :c:type:`struct dma_buf_map <dma_buf_map>` can be initialized
- * statically with DMA_BUF_MAP_INIT_VADDR(), or at runtime with
- * dma_buf_map_set_vaddr(). These helpers will set an address in system memory.
- *
- * .. code-block:: c
- *
- *	struct dma_buf_map map = DMA_BUF_MAP_INIT_VADDR(0xdeadbeaf);
- *
- *	dma_buf_map_set_vaddr(&map. 0xdeadbeaf);
- *
- * To set an address in I/O memory, use dma_buf_map_set_vaddr_iomem().
- *
- * .. code-block:: c
- *
- *	dma_buf_map_set_vaddr_iomem(&map. 0xdeadbeaf);
- *
- * Instances of struct dma_buf_map do not have to be cleaned up, but
- * can be cleared to NULL with dma_buf_map_clear(). Cleared mappings
- * always refer to system memory.
- *
- * .. code-block:: c
- *
- *	dma_buf_map_clear(&map);
- *
- * Test if a mapping is valid with either dma_buf_map_is_set() or
- * dma_buf_map_is_null().
- *
- * .. code-block:: c
- *
- *	if (dma_buf_map_is_set(&map) != dma_buf_map_is_null(&map))
- *		// always true
- *
- * Instances of :c:type:`struct dma_buf_map <dma_buf_map>` can be compared
- * for equality with dma_buf_map_is_equal(). Mappings the point to different
- * memory spaces, system or I/O, are never equal. That's even true if both
- * spaces are located in the same address space, both mappings contain the
- * same address value, or both mappings refer to NULL.
- *
- * .. code-block:: c
- *
- *	struct dma_buf_map sys_map; // refers to system memory
- *	struct dma_buf_map io_map; // refers to I/O memory
- *
- *	if (dma_buf_map_is_equal(&sys_map, &io_map))
- *		// always false
- *
- * A set up instance of struct dma_buf_map can be used to access or manipulate
- * the buffer memory. Depending on the location of the memory, the provided
- * helpers will pick the correct operations. Data can be copied into the memory
- * with dma_buf_map_memcpy_to(). The address can be manipulated with
- * dma_buf_map_incr().
- *
- * .. code-block:: c
- *
- *	const void *src = ...; // source buffer
- *	size_t len = ...; // length of src
- *
- *	dma_buf_map_memcpy_to(&map, src, len);
- *	dma_buf_map_incr(&map, len); // go to first byte after the memcpy

- * ``GENHD_FL_REMOVABLE`` (0x0001): indicates that the block device
- * gives access to removable media.
- * When set, the device remains present even when media is not
- * inserted.
- * Must not be set for devices which are removed entirely when the
- * media is removed.
- *
- * ``GENHD_FL_CD`` (0x0008): the block device is a CD-ROM-style
- * device.
- * Affects responses to the ``CDROM_GET_CAPABILITY`` ioctl.
- *
- * ``GENHD_FL_SUPPRESS_PARTITION_INFO`` (0x0020): don't include
- * partition information in ``/proc/partitions`` or in the output of
- * printk_all_partitions().
- * Used for the null block device and some MMC devices.
- *
- * ``GENHD_FL_EXT_DEVT`` (0x0040): the driver supports extended
- * dynamic ``dev_t``, i.e. it wants extended device numbers
- * (``BLOCK_EXT_MAJOR``).
- * This affects the maximum number of partitions.
- *
- * ``GENHD_FL_NATIVE_CAPACITY`` (0x0080): based on information in the
- * partition table, the device's capacity has been extended to its
- * native capacity; i.e. the device has hidden capacity used by one
- * of the partitions (this is a flag used so that native capacity is
- * only ever unlocked once).
- *
- * ``GENHD_FL_BLOCK_EVENTS_ON_EXCL_WRITE`` (0x0100): event polling is
- * blocked whenever a writer holds an exclusive lock.
- *
- * ``GENHD_FL_NO_PART_SCAN`` (0x0200): partition scanning is disabled.
- * Used for loop devices in their default settings and some MMC
- * devices.
- *
- * ``GENHD_FL_HIDDEN`` (0x0400): the block device is hidden; it
- * doesn't produce events, doesn't appear in sysfs, and doesn't have
- * an associated ``bdev``.
- * Implies ``GENHD_FL_SUPPRESS_PARTITION_INFO`` and
- * ``GENHD_FL_NO_PART_SCAN``.
- * Used for multipath devices.

- *
- * %__GFP_MOVABLE (also a zone modifier) indicates that the page can be

- *
- * %__GFP_RECLAIMABLE is used for slab allocations that specify
- * SLAB_RECLAIM_ACCOUNT and whose pages can be freed via shrinkers.
- *
- * %__GFP_WRITE indicates the caller intends to dirty the page. Where possible,
- * these pages will be spread between local zones to avoid all the dirty
- * pages being in one zone (fair zone allocation policy).
- *
- * %__GFP_HARDWALL enforces the cpuset memory allocation policy.
- *
- * %__GFP_THISNODE forces the allocation to be satisfied from the requested
- * node with no fallbacks or placement policy enforcements.
- *
- * %__GFP_ACCOUNT causes the allocation to be accounted to kmemcg.

- * %__GFP_ATOMIC indicates that the caller cannot reclaim or sleep and is

- * Users of this flag have to be extremely careful to not deplete the reserve
- * completely and implement a throttling mechanism which controls the
- * consumption of the reserve based on the amount of freed memory.
- * Usage of a pre-allocated pool (e.g. mempool) should be always considered

- *
- * Reclaim modifiers
- * ~~~~~~~~~~~~~~~~~
- * Please note that all the following flags are only applicable to sleepable
- * allocations (e.g. %GFP_NOWAIT and %GFP_ATOMIC will ignore them).
- *
- * %__GFP_IO can start physical IO.
- *
- * %__GFP_FS can call down to the low-level FS. Clearing the flag avoids the
- * allocator recursing into the filesystem which might already be holding
- * locks.
- *
- * %__GFP_DIRECT_RECLAIM indicates that the caller may enter direct reclaim.
- * This flag can be cleared to avoid unnecessary delays when a fallback
- * option is available.
- *
- * %__GFP_KSWAPD_RECLAIM indicates that the caller wants to wake kswapd when
- * the low watermark is reached and have it reclaim pages until the high
- * watermark is reached. A caller may wish to clear this flag when fallback
- * options are available and the reclaim is likely to disrupt the system. The
- * canonical example is THP allocation where a fallback is cheap but
- * reclaim/compaction may cause indirect stalls.
- *
- * %__GFP_RECLAIM is shorthand to allow/forbid both direct and kswapd reclaim.
- *
- * The default allocator behavior depends on the request size. We have a concept
- * of so called costly allocations (with order > %PAGE_ALLOC_COSTLY_ORDER).
- * !costly allocations are too essential to fail so they are implicitly
- * non-failing by default (with some exceptions like OOM victims might fail so
- * the caller still has to check for failures) while costly requests try to be
- * not disruptive and back off even without invoking the OOM killer.
- * The following three modifiers might be used to override some of these
- * implicit rules
- *
- * %__GFP_NORETRY: The VM implementation will try only very lightweight
- * memory direct reclaim to get some memory under memory pressure (thus
- * it can sleep). It will avoid disruptive actions like OOM killer. The
- * caller must handle the failure which is quite likely to happen under
- * heavy memory pressure. The flag is suitable when failure can easily be
- * handled at small cost, such as reduced throughput
- *
- * %__GFP_RETRY_MAYFAIL: The VM implementation will retry memory reclaim
- * procedures that have previously failed if there is some indication
- * that progress has been made else where.  It can wait for other
- * tasks to attempt high level approaches to freeing memory such as
- * compaction (which removes fragmentation) and page-out.
- * There is still a definite limit to the number of retries, but it is
- * a larger limit than with %__GFP_NORETRY.
- * Allocations with this flag may fail, but only when there is

- * cannot handle allocation failures. The allocation could block

- *
- * Useful GFP flag combinations
- * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- *
- * Useful GFP flag combinations that are commonly used. It is recommended
- * that subsystems start with one of these combinations and then set/clear
- * %__GFP_FOO flags as necessary.
- *
- * %GFP_ATOMIC users can not sleep and need the allocation to succeed. A lower
- * watermark is applied to allow access to "atomic reserves".
- * The current implementation doesn't support NMI and few other strict
- * non-preemptive contexts (e.g. raw_spin_lock). The same applies to %GFP_NOWAIT.
- *
- * %GFP_KERNEL is typical for kernel-internal allocations. The caller requires
- * %ZONE_NORMAL or a lower zone for direct access but can direct reclaim.
- *
- * %GFP_KERNEL_ACCOUNT is the same as GFP_KERNEL, except the allocation is
- * accounted to kmemcg.
- *
- * %GFP_NOWAIT is for kernel allocations that should not stall for direct
- * reclaim, start physical IO or use any filesystem callback.
- *
- * %GFP_NOIO will use direct reclaim to discard clean pages or slab pages
- * that do not require the starting of any physical IO.
- * Please try to avoid using this flag directly and instead use
- * memalloc_noio_{save,restore} to mark the whole scope which cannot
- * perform any IO with a short explanation why. All allocation requests
- * will inherit GFP_NOIO implicitly.
- *
- * %GFP_NOFS will use direct reclaim but will not use any filesystem interfaces.
- * Please try to avoid using this flag directly and instead use
- * memalloc_nofs_{save,restore} to mark the whole scope which cannot/shouldn't
- * recurse into the FS layer with a short explanation why. All allocation
- * requests will inherit GFP_NOFS implicitly.
- *
- * %GFP_USER is for userspace allocations that also need to be directly
- * accessibly by the kernel or hardware. It is typically used by hardware
- * for buffers that are mapped to userspace (e.g. graphics) that hardware
- * still must DMA to. cpuset limits are enforced for these allocations.
- *
- * %GFP_DMA exists for historical reasons and should be avoided where possible.
- * The flags indicates that the caller requires that the lowest zone be
- * used (%ZONE_DMA or 16M on x86-64). Ideally, this would be removed but
- * it would require careful auditing as some users really require it and
- * others use the flag to avoid lowmem reserves in %ZONE_DMA and treat the
- * lowest zone as a type of emergency reserve.
- *
- * %GFP_DMA32 is similar to %GFP_DMA except that the caller requires a 32-bit
- * address.
- *
- * %GFP_HIGHUSER is for userspace allocations that may be mapped to userspace,
- * do not need to be directly accessible by the kernel but that cannot
- * move once in use. An example may be a hardware allocation that maps
- * data directly into userspace but has no addressing limitations.
- *
- * %GFP_HIGHUSER_MOVABLE is for userspace allocations that the kernel does not
- * need direct access to but can use kmap() when access is required. They
- * are expected to be movable via page reclaim or page migration. Typically,
- * pages on the LRU would also be allocated with %GFP_HIGHUSER_MOVABLE.
- *
- * %GFP_TRANSHUGE and %GFP_TRANSHUGE_LIGHT are used for THP allocations. They
- * are compound allocations that will generally fail quickly if memory is not
- * available and will not wake kswapd/kcompactd on failure. The _LIGHT
- * version does not attempt reclaim/compaction at all and is by default used
- * in page fault path, while the non-light is used by khugepaged.

+ * Reclaim modifiers
+ * -----------------
+ * Please note that all the following flags are only applicable to sleepable
+ * allocations (e.g. %GFP_NOWAIT and %GFP_ATOMIC will ignore them).
+ *
+ * %__GFP_IO can start physical IO.
+ *
+ * %__GFP_FS can call down to the low-level FS. Clearing the flag avoids the
+ * allocator recursing into the filesystem which might already be holding
+ * locks.
+ *
+ * %__GFP_DIRECT_RECLAIM indicates that the caller may enter direct reclaim.
+ * This flag can be cleared to avoid unnecessary delays when a fallback
+ * option is available.
+ *
+ * %__GFP_KSWAPD_RECLAIM indicates that the caller wants to wake kswapd when
+ * the low watermark is reached and have it reclaim pages until the high
+ * watermark is reached. A caller may wish to clear this flag when fallback
+ * options are available and the reclaim is likely to disrupt the system. The
+ * canonical example is THP allocation where a fallback is cheap but
+ * reclaim/compaction may cause indirect stalls.
+ *
+ * %__GFP_RECLAIM is shorthand to allow/forbid both direct and kswapd reclaim.
+ *
+ * The default allocator behavior depends on the request size. We have a concept
+ * of so called costly allocations (with order > %PAGE_ALLOC_COSTLY_ORDER).
+ * !costly allocations are too essential to fail so they are implicitly
+ * non-failing by default (with some exceptions like OOM victims might fail so
+ * the caller still has to check for failures) while costly requests try to be
+ * not disruptive and back off even without invoking the OOM killer.
+ * The following three modifiers might be used to override some of these
+ * implicit rules
+ *
+ * %__GFP_NORETRY: The VM implementation will try only very lightweight
+ * memory direct reclaim to get some memory under memory pressure (thus
+ * it can sleep). It will avoid disruptive actions like OOM killer. The
+ * caller must handle the failure which is quite likely to happen under
+ * heavy memory pressure. The flag is suitable when failure can easily be
+ * handled at small cost, such as reduced throughput
+ *
+ * %__GFP_RETRY_MAYFAIL: The VM implementation will retry memory reclaim
+ * procedures that have previously failed if there is some indication
+ * that progress has been made else where.  It can wait for other
+ * tasks to attempt high level approaches to freeing memory such as
+ * compaction (which removes fragmentation) and page-out.
+ * There is still a definite limit to the number of retries, but it is
+ * a larger limit than with %__GFP_NORETRY.
+ * Allocations with this flag may fail, but only when there is
+ * genuinely little unused memory. While these allocations do not
+ * directly trigger the OOM killer, their failure indicates that
+ * the system is likely to need to use the OOM killer soon.  The
+ * caller must handle failure, but can reasonably do so by failing
+ * a higher-level request, or completing it only in a much less
+ * efficient manner.
+ * If the allocation does fail, and the caller is in a position to
+ * free some non-essential memory, doing so could benefit the system
+ * as a whole.
+ *
+ * %__GFP_NOFAIL: The VM implementation _must_ retry infinitely: the caller
+ * cannot handle allocation failures. The allocation could block
+ * indefinitely but will never return with failure. Testing for
+ * failure is pointless.
+ * New users should be evaluated carefully (and the flag should be
+ * used only when there is no reasonable failure policy) but it is
+ * definitely preferable to use the flag rather than opencode endless

+ *
+ * %GFP_USER is for userspace allocations that also need to be directly
+ * accessibly by the kernel or hardware. It is typically used by hardware
+ * for buffers that are mapped to userspace (e.g. graphics) that hardware
+ * still must DMA to. cpuset limits are enforced for these allocations.
+ *
+ * %GFP_DMA exists for historical reasons and should be avoided where possible.
+ * The flags indicates that the caller requires that the lowest zone be
+ * used (%ZONE_DMA or 16M on x86-64). Ideally, this would be removed but
+ * it would require careful auditing as some users really require it and
+ * others use the flag to avoid lowmem reserves in %ZONE_DMA and treat the
+ * lowest zone as a type of emergency reserve.
+ *
+ * %GFP_DMA32 is similar to %GFP_DMA except that the caller requires a 32-bit
+ * address. Note that kmalloc(..., GFP_DMA32) does not return DMA32 memory
+ * because the DMA32 kmalloc cache array is not implemented.
+ * (Reason: there is no such user in kernel).
+ *
+ * %GFP_HIGHUSER is for userspace allocations that may be mapped to userspace,
+ * do not need to be directly accessible by the kernel but that cannot
+ * move once in use. An example may be a hardware allocation that maps
+ * data directly into userspace but has no addressing limitations.
+ *
+ * %GFP_HIGHUSER_MOVABLE is for userspace allocations that the kernel does not
+ * need direct access to but can use kmap() when access is required. They
+ * are expected to be movable via page reclaim or page migration. Typically,
+ * pages on the LRU would also be allocated with %GFP_HIGHUSER_MOVABLE.
+ *
+ * %GFP_TRANSHUGE and %GFP_TRANSHUGE_LIGHT are used for THP allocations. They
+ * are compound allocations that will generally fail quickly if memory is not
+ * available and will not wake kswapd/kcompactd on failure. The _LIGHT
+ * version does not attempt reclaim/compaction at all and is by default used
+ * in page fault path, while the non-light is used by khugepaged.

+ * Device operating modes
+ * @INDIO_DIRECT_MODE: There is an access to either:
+ * a) The last single value available for devices that do not provide
+ *    on-demand reads.
+ * b) A new value after performing an on-demand read otherwise.
+ * On most devices, this is a single-shot read. On some devices with data
+ * streams without an 'on-demand' function, this might also be the 'last value'
+ * feature. Above all, this mode internally means that we are not in any of the
+ * other modes, and sysfs reads should work.
+ * Device drivers should inform the core if they support this mode.
+ * @INDIO_BUFFER_TRIGGERED: Common mode when dealing with kfifo buffers.
+ * It indicates that an explicit trigger is required. This requests the core to
+ * attach a poll function when enabling the buffer, which is indicated by the
+ * _TRIGGERED suffix.
+ * The core will ensure this mode is set when registering a triggered buffer
+ * with iio_triggered_buffer_setup().
+ * @INDIO_BUFFER_SOFTWARE: Another kfifo buffer mode, but not event triggered.
+ * No poll function can be attached because there is no triggered infrastructure
+ * we can use to cause capture. There is a kfifo that the driver will fill, but
+ * not "only one scan at a time". Typically, hardware will have a buffer that
+ * can hold multiple scans. Software may read one or more scans at a single time
+ * and push the available data to a Kfifo. This means the core will not attach
+ * any poll function when enabling the buffer.
+ * The core will ensure this mode is set when registering a simple kfifo buffer
+ * with devm_iio_kfifo_buffer_setup().
+ * @INDIO_BUFFER_HARDWARE: For specific hardware, if unsure do not use this mode.
+ * Same as above but this time the buffer is not a kfifo where we have direct
+ * access to the data. Instead, the consumer driver must access the data through
+ * non software visible channels (or DMA when there is no demux possible in
+ * software)
+ * The core will ensure this mode is set when registering a dmaengine buffer
+ * with devm_iio_dmaengine_buffer_setup().
+ * @INDIO_EVENT_TRIGGERED: Very unusual mode.
+ * Triggers usually refer to an external event which will start data capture.
+ * Here it is kind of the opposite as, a particular state of the data might
+ * produce an event which can be considered as an event. We don't necessarily
+ * have access to the data itself, but to the event produced. For example, this
+ * can be a threshold detector. The internal path of this mode is very close to
+ * the INDIO_BUFFER_TRIGGERED mode.
+ * The core will ensure this mode is set when registering a triggered event.
+ * @INDIO_HARDWARE_TRIGGERED: Very unusual mode.
+ * Here, triggers can result in data capture and can be routed to multiple
+ * hardware components, which make them close to regular triggers in the way
+ * they must be managed by the core, but without the entire interrupts/poll
+ * functions burden. Interrupts are irrelevant as the data flow is hardware
+ * mediated and distributed.

+/**
+ * DOC: overview
+ *
+ * When accessing a memory region, depending on its location, users may have to
+ * access it with I/O operations or memory load/store operations. For example,
+ * copying to system memory could be done with memcpy(), copying to I/O memory
+ * would be done with memcpy_toio().
+ *
+ * .. code-block:: c
+ *
+ *	void *vaddr = ...; // pointer to system memory
+ *	memcpy(vaddr, src, len);
+ *
+ *	void *vaddr_iomem = ...; // pointer to I/O memory
+ *	memcpy_toio(vaddr_iomem, src, len);
+ *
+ * The user of such pointer may not have information about the mapping of that
+ * region or may want to have a single code path to handle operations on that
+ * buffer, regardless if it's located in system or IO memory. The type
+ * :c:type:`struct iosys_map <iosys_map>` and its helpers abstract that so the
+ * buffer can be passed around to other drivers or have separate duties inside
+ * the same driver for allocation, read and write operations.
+ *
+ * Open-coding access to :c:type:`struct iosys_map <iosys_map>` is considered
+ * bad style. Rather then accessing its fields directly, use one of the provided
+ * helper functions, or implement your own. For example, instances of
+ * :c:type:`struct iosys_map <iosys_map>` can be initialized statically with
+ * IOSYS_MAP_INIT_VADDR(), or at runtime with iosys_map_set_vaddr(). These
+ * helpers will set an address in system memory.
+ *
+ * .. code-block:: c
+ *
+ *	struct iosys_map map = IOSYS_MAP_INIT_VADDR(0xdeadbeaf);
+ *
+ *	iosys_map_set_vaddr(&map, 0xdeadbeaf);
+ *
+ * To set an address in I/O memory, use IOSYS_MAP_INIT_VADDR_IOMEM() or
+ * iosys_map_set_vaddr_iomem().
+ *
+ * .. code-block:: c
+ *
+ *	struct iosys_map map = IOSYS_MAP_INIT_VADDR_IOMEM(0xdeadbeaf);
+ *
+ *	iosys_map_set_vaddr_iomem(&map, 0xdeadbeaf);
+ *
+ * Instances of struct iosys_map do not have to be cleaned up, but
+ * can be cleared to NULL with iosys_map_clear(). Cleared mappings
+ * always refer to system memory.
+ *
+ * .. code-block:: c
+ *
+ *	iosys_map_clear(&map);
+ *
+ * Test if a mapping is valid with either iosys_map_is_set() or
+ * iosys_map_is_null().
+ *
+ * .. code-block:: c
+ *
+ *	if (iosys_map_is_set(&map) != iosys_map_is_null(&map))
+ *		// always true
+ *
+ * Instances of :c:type:`struct iosys_map <iosys_map>` can be compared for
+ * equality with iosys_map_is_equal(). Mappings that point to different memory
+ * spaces, system or I/O, are never equal. That's even true if both spaces are
+ * located in the same address space, both mappings contain the same address
+ * value, or both mappings refer to NULL.
+ *
+ * .. code-block:: c
+ *
+ *	struct iosys_map sys_map; // refers to system memory
+ *	struct iosys_map io_map; // refers to I/O memory
+ *
+ *	if (iosys_map_is_equal(&sys_map, &io_map))
+ *		// always false
+ *
+ * A set up instance of struct iosys_map can be used to access or manipulate the
+ * buffer memory. Depending on the location of the memory, the provided helpers
+ * will pick the correct operations. Data can be copied into the memory with
+ * iosys_map_memcpy_to(). The address can be manipulated with iosys_map_incr().
+ *
+ * .. code-block:: c
+ *
+ *	const void *src = ...; // source buffer
+ *	size_t len = ...; // length of src

+ * The maple state is defined in the struct ma_state and is used to keep track
+ * of information during operations, and even between operations when using the
+ * advanced API.
+ *
+ * If state->node has bit 0 set then it references a tree location which is not
+ * a node (eg the root).  If bit 1 is set, the rest of the bits are a negative
+ * errno.  Bit 2 (the 'unallocated slots' bit) is clear.  Bits 3-6 indicate the
+ * node type.
+ *
+ * state->alloc either has a request number of nodes or an allocated node.  If
+ * stat->alloc has a requested number of nodes, the first bit will be set (0x1)
+ * and the remaining bits are the value.  If state->alloc is a node, then the
+ * node will be of type maple_alloc.  maple_alloc has MAPLE_NODE_SLOTS - 1 for
+ * storing more allocated nodes, a total number of nodes allocated, and the
+ * node_count in this node.  node_count is the number of allocated nodes in this
+ * node.  The scaling beyond MAPLE_NODE_SLOTS - 1 is handled by storing further
+ * nodes into state->alloc->slot[0]'s node.  Nodes are taken from state->alloc
+ * by removing a node from the state->alloc node until state->alloc->node_count
+ * is 1, when state->alloc is returned and the state->alloc->slot[0] is promoted
+ * to state->alloc.  Nodes are pushed onto state->alloc by putting the current
+ * state->alloc into the pushed node's slot[0].
+ *
+ * The state also contains the implied min/max of the state->node, the depth of
+ * this search, and the offset. The implied min/max are either from the parent
+ * node or are 0-oo for the root node.  The depth is incremented or decremented
+ * every time a node is walked down or up.  The offset is the slot/pivot of
+ * interest in the node - either for reading or writing.
+ *
+ * When returning a value the maple state index and last respectively contain
+ * the start and end of the range for the entry.  Ranges are inclusive in the

- * @FAULT_FLAG_RETRY_NOWAIT: Don't drop mmap_lock and wait when retrying.

- * @FAULT_FLAG_INTERRUPTIBLE: The fault can be interrupted by non-fatal signals.
- *
- * About @FAULT_FLAG_ALLOW_RETRY and @FAULT_FLAG_TRIED: we can specify
- * whether we would allow page faults to retry by specifying these two
- * fault flags correctly.  Currently there can be three legal combinations:
- *
- * (a) ALLOW_RETRY and !TRIED:  this means the page fault allows retry, and

- *                              we've already tried at least once
- *
- * (c) !ALLOW_RETRY and !TRIED: this means the page fault does not allow retry
- *
- * The unlisted combination (!ALLOW_RETRY && TRIED) is illegal and should never
- * be used.  Note that page faults can be allowed to retry for multiple times,
- * in which case we'll have an initial fault with flags (a) then later on
- * continuous faults with flags (b).  We should always try to detect pending
- * signals before a retry to make sure the continuous page faults can still be

+ * Practically this means that the Li-ions are wandering back and forth in the

+ *
+ * Maintenance charging uses the voltages from this table: a table of settings
+ * is traversed using a slightly lower current and voltage than what is used for
+ * CC/CV charging. The maintenance charging will for safety reasons not go on
+ * indefinately: we lower the current and voltage with successive maintenance
+ * settings, then disable charging completely after we reach the last one,
+ * and after that we do not restart charging until we reach
+ * charge_restart_voltage_uv (see struct power_supply_battery_info) and restart
+ * ordinary CC/CV charging from there.
+ *
+ * As an example, a Samsung EB425161LA Lithium-Ion battery is CC/CV charged
+ * at 900mA to 4340mV, then maintenance charged at 600mA and 4150mV for up to
+ * 60 hours, then maintenance charged at 600mA and 4100mV for up to 200 hours.
+ * After this the charge cycle is restarted waiting for
+ * charge_restart_voltage_uv.
+ *
+ * For most mobile electronics this type of maintenance charging is enough for
+ * the user to disconnect the device and make use of it before both maintenance
+ * charging cycles are complete, if the current and voltage has been chosen
+ * appropriately. These need to be determined from battery discharge curves
+ * and expected standby current.
+ *
+ * If the voltage anyway drops to charge_restart_voltage_uv during maintenance
+ * charging, ordinary CC/CV charging is restarted. This can happen if the
+ * device is e.g. actively used during charging, so more current is drawn than
+ * the expected stand-by current. Also overvoltage protection will be applied

+ * DETERMINING BATTERY CAPACITY:
+ *
+ * Several members of the struct deal with trying to determine the remaining

+ * many chargers uses a so-called fuel gauge or coloumb counter that measure
+ * how much charge goes into the battery and how much goes out (+/- leak
+ * consumption). This does not help if we do not know how much capacity the
+ * battery has to begin with, such as when it is first used or was taken out
+ * and charged in a separate charger. Therefore many capacity algorithms use
+ * the open circuit voltage with a look-up table to determine the rough
+ * capacity of the battery. The open circuit voltage can be conceptualized
+ * with an ideal voltage source (V) in series with an internal resistance (Ri)
+ * like this:
+ *
+ *      +-------> IBAT >----------------+
+ *      |                    ^          |
+ *     [ ] Ri                |          |
+ *      |                    | VBAT     |
+ *      o <----------        |          |
+ *     +|           ^        |         [ ] Rload
+ *    .---.         |        |          |
+ *    | V |         | OCV    |          |
+ *    '---'         |        |          |
+ *      |           |        |          |
+ *  GND +-------------------------------+
+ *
+ * If we disconnect the load (here simplified as a fixed resistance Rload)
+ * and measure VBAT with a infinite impedance voltage meter we will get
+ * VBAT = OCV and this assumption is sometimes made even under load, assuming
+ * Rload is insignificant. However this will be of dubious quality because the
+ * load is rarely that small and Ri is strongly nonlinear depending on
+ * temperature and how much capacity is left in the battery due to the
+ * chemistry involved.
+ *
+ * In many practical applications we cannot just disconnect the battery from
+ * the load, so instead we often try to measure the instantaneous IBAT (the
+ * current out from the battery), estimate the Ri and thus calculate the
+ * voltage drop over Ri and compensate like this:
+ *
+ *   OCV = VBAT - (IBAT * Ri)
+ *
+ * The tables vbat2ri_discharging and vbat2ri_charging are used to determine
+ * (by interpolation) the Ri from the VBAT under load. These curves are highly
+ * nonlinear and may need many datapoints but can be found in datasheets for
+ * some batteries. This gives the compensated open circuit voltage (OCV) for
+ * the battery even under load. Using this method will also compensate for
+ * temperature changes in the environment: this will also make the internal
+ * resistance change, and it will affect the VBAT under load, so correlating
+ * VBAT to Ri takes both remaining capacity and temperature into consideration.
+ *
+ * Alternatively a manufacturer can specify how the capacity of the battery
+ * is dependent on the battery temperature which is the main factor affecting
+ * Ri. As we know all checmical reactions are faster when it is warm and slower
+ * when it is cold. You can put in 1500mAh and only get 800mAh out before the
+ * voltage drops too low for example. This effect is also highly nonlinear and
+ * the purpose of the table resist_table: this will take a temperature and
+ * tell us how big percentage of Ri the specified temperature correlates to.
+ * Usually we have 100% of the factory_internal_resistance_uohm at 25 degrees
+ * Celsius.
+ *
  * The power supply class itself doesn't use this struct as of now.

  * This structure describes all the operations that can be done on the

+ * physical hardware.
+ *
+ * @tx_empty: ``unsigned int ()(struct uart_port *port)``
+ *
+ *	This function tests whether the transmitter fifo and shifter for the
+ *	@port is empty. If it is empty, this function should return
+ *	%TIOCSER_TEMT, otherwise return 0. If the port does not support this
+ *	operation, then it should return %TIOCSER_TEMT.
+ *
+ *	Locking: none.
+ *	Interrupts: caller dependent.
+ *	This call must not sleep
+ *
+ * @set_mctrl: ``void ()(struct uart_port *port, unsigned int mctrl)``
+ *
+ *	This function sets the modem control lines for @port to the state
+ *	described by @mctrl. The relevant bits of @mctrl are:
+ *
+ *		- %TIOCM_RTS	RTS signal.
+ *		- %TIOCM_DTR	DTR signal.
+ *		- %TIOCM_OUT1	OUT1 signal.
+ *		- %TIOCM_OUT2	OUT2 signal.
+ *		- %TIOCM_LOOP	Set the port into loopback mode.
+ *
+ *	If the appropriate bit is set, the signal should be driven
+ *	active.  If the bit is clear, the signal should be driven
+ *	inactive.
+ *
+ *	Locking: @port->lock taken.
+ *	Interrupts: locally disabled.
+ *	This call must not sleep
+ *
+ * @get_mctrl: ``unsigned int ()(struct uart_port *port)``
+ *
+ *	Returns the current state of modem control inputs of @port. The state
+ *	of the outputs should not be returned, since the core keeps track of
+ *	their state. The state information should include:
+ *
+ *		- %TIOCM_CAR	state of DCD signal
+ *		- %TIOCM_CTS	state of CTS signal
+ *		- %TIOCM_DSR	state of DSR signal
+ *		- %TIOCM_RI	state of RI signal
+ *
+ *	The bit is set if the signal is currently driven active.  If
+ *	the port does not support CTS, DCD or DSR, the driver should
+ *	indicate that the signal is permanently active. If RI is
+ *	not available, the signal should not be indicated as active.
+ *
+ *	Locking: @port->lock taken.
+ *	Interrupts: locally disabled.
+ *	This call must not sleep
+ *
+ * @stop_tx: ``void ()(struct uart_port *port)``
+ *
+ *	Stop transmitting characters. This might be due to the CTS line
+ *	becoming inactive or the tty layer indicating we want to stop
+ *	transmission due to an %XOFF character.
+ *
+ *	The driver should stop transmitting characters as soon as possible.
+ *
+ *	Locking: @port->lock taken.
+ *	Interrupts: locally disabled.
+ *	This call must not sleep
+ *
+ * @start_tx: ``void ()(struct uart_port *port)``
+ *
+ *	Start transmitting characters.
+ *
+ *	Locking: @port->lock taken.
+ *	Interrupts: locally disabled.
+ *	This call must not sleep
+ *
+ * @throttle: ``void ()(struct uart_port *port)``
+ *
+ *	Notify the serial driver that input buffers for the line discipline are
+ *	close to full, and it should somehow signal that no more characters
+ *	should be sent to the serial port.
+ *	This will be called only if hardware assisted flow control is enabled.
+ *
+ *	Locking: serialized with @unthrottle() and termios modification by the
+ *	tty layer.
+ *
+ * @unthrottle: ``void ()(struct uart_port *port)``
+ *
+ *	Notify the serial driver that characters can now be sent to the serial
+ *	port without fear of overrunning the input buffers of the line
+ *	disciplines.
+ *
+ *	This will be called only if hardware assisted flow control is enabled.
+ *
+ *	Locking: serialized with @throttle() and termios modification by the
+ *	tty layer.
+ *
+ * @send_xchar: ``void ()(struct uart_port *port, char ch)``
+ *
+ *	Transmit a high priority character, even if the port is stopped. This
+ *	is used to implement XON/XOFF flow control and tcflow(). If the serial
+ *	driver does not implement this function, the tty core will append the
+ *	character to the circular buffer and then call start_tx() / stop_tx()
+ *	to flush the data out.
+ *
+ *	Do not transmit if @ch == '\0' (%__DISABLED_CHAR).
+ *
+ *	Locking: none.
+ *	Interrupts: caller dependent.
+ *
+ * @start_rx: ``void ()(struct uart_port *port)``
+ *
+ *	Start receiving characters.
+ *
+ *	Locking: @port->lock taken.
+ *	Interrupts: locally disabled.
+ *	This call must not sleep
+ *
+ * @stop_rx: ``void ()(struct uart_port *port)``
+ *
+ *	Stop receiving characters; the @port is in the process of being closed.
+ *
+ *	Locking: @port->lock taken.
+ *	Interrupts: locally disabled.
+ *	This call must not sleep
+ *
+ * @enable_ms: ``void ()(struct uart_port *port)``
+ *
+ *	Enable the modem status interrupts.
+ *
+ *	This method may be called multiple times. Modem status interrupts
+ *	should be disabled when the @shutdown() method is called.
+ *
+ *	Locking: @port->lock taken.
+ *	Interrupts: locally disabled.
+ *	This call must not sleep
+ *
+ * @break_ctl: ``void ()(struct uart_port *port, int ctl)``
+ *
+ *	Control the transmission of a break signal. If @ctl is nonzero, the
+ *	break signal should be transmitted. The signal should be terminated
+ *	when another call is made with a zero @ctl.
+ *
+ *	Locking: caller holds tty_port->mutex
+ *
+ * @startup: ``int ()(struct uart_port *port)``
+ *
+ *	Grab any interrupt resources and initialise any low level driver state.
+ *	Enable the port for reception. It should not activate RTS nor DTR;
+ *	this will be done via a separate call to @set_mctrl().
+ *
+ *	This method will only be called when the port is initially opened.
+ *
+ *	Locking: port_sem taken.
+ *	Interrupts: globally disabled.
+ *
+ * @shutdown: ``void ()(struct uart_port *port)``
+ *
+ *	Disable the @port, disable any break condition that may be in effect,
+ *	and free any interrupt resources. It should not disable RTS nor DTR;
+ *	this will have already been done via a separate call to @set_mctrl().
+ *
+ *	Drivers must not access @port->state once this call has completed.
+ *
+ *	This method will only be called when there are no more users of this
+ *	@port.
+ *
+ *	Locking: port_sem taken.

+ *
+ * @flush_buffer: ``void ()(struct uart_port *port)``
+ *
+ *	Flush any write buffers, reset any DMA state and stop any ongoing DMA
+ *	transfers.
+ *
+ *	This will be called whenever the @port->state->xmit circular buffer is
+ *	cleared.
+ *
+ *	Locking: @port->lock taken.
+ *	Interrupts: locally disabled.
+ *	This call must not sleep
+ *
+ * @set_termios: ``void ()(struct uart_port *port, struct ktermios *new,
+ *			struct ktermios *old)``
+ *
+ *	Change the @port parameters, including word length, parity, stop bits.
+ *	Update @port->read_status_mask and @port->ignore_status_mask to
+ *	indicate the types of events we are interested in receiving. Relevant
+ *	ktermios::c_cflag bits are:
+ *
+ *	- %CSIZE - word size
+ *	- %CSTOPB - 2 stop bits
+ *	- %PARENB - parity enable
+ *	- %PARODD - odd parity (when %PARENB is in force)
+ *	- %ADDRB - address bit (changed through uart_port::rs485_config()).
+ *	- %CREAD - enable reception of characters (if not set, still receive
+ *	  characters from the port, but throw them away).
+ *	- %CRTSCTS - if set, enable CTS status change reporting.
+ *	- %CLOCAL - if not set, enable modem status change reporting.
+ *
+ *	Relevant ktermios::c_iflag bits are:
+ *
+ *	- %INPCK - enable frame and parity error events to be passed to the TTY
+ *	  layer.
+ *	- %BRKINT / %PARMRK - both of these enable break events to be passed to
+ *	  the TTY layer.
+ *	- %IGNPAR - ignore parity and framing errors.
+ *	- %IGNBRK - ignore break errors. If %IGNPAR is also set, ignore overrun
+ *	  errors as well.
+ *
+ *	The interaction of the ktermios::c_iflag bits is as follows (parity
+ *	error given as an example):
+ *
+ *	============ ======= ======= =========================================
+ *	Parity error INPCK   IGNPAR
+ *	============ ======= ======= =========================================
+ *	n/a	     0	     n/a     character received, marked as %TTY_NORMAL
+ *	None	     1	     n/a     character received, marked as %TTY_NORMAL
+ *	Yes	     1	     0	     character received, marked as %TTY_PARITY
+ *	Yes	     1	     1	     character discarded
+ *	============ ======= ======= =========================================
+ *
+ *	Other flags may be used (eg, xon/xoff characters) if your hardware
+ *	supports hardware "soft" flow control.
+ *
+ *	Locking: caller holds tty_port->mutex
+ *	Interrupts: caller dependent.
+ *	This call must not sleep
+ *
+ * @set_ldisc: ``void ()(struct uart_port *port, struct ktermios *termios)``
+ *
+ *	Notifier for discipline change. See
+ *	Documentation/driver-api/tty/tty_ldisc.rst.
+ *
+ *	Locking: caller holds tty_port->mutex
+ *
+ * @pm: ``void ()(struct uart_port *port, unsigned int state,
+ *		 unsigned int oldstate)``
+ *
+ *	Perform any power management related activities on the specified @port.
+ *	@state indicates the new state (defined by enum uart_pm_state),
+ *	@oldstate indicates the previous state.
+ *
+ *	This function should not be used to grab any resources.
+ *
+ *	This will be called when the @port is initially opened and finally
+ *	closed, except when the @port is also the system console. This will
+ *	occur even if %CONFIG_PM is not set.
+ *
+ *	Locking: none.
+ *	Interrupts: caller dependent.
+ *
+ * @type: ``const char *()(struct uart_port *port)``
+ *
+ *	Return a pointer to a string constant describing the specified @port,
+ *	or return %NULL, in which case the string 'unknown' is substituted.
+ *
+ *	Locking: none.
+ *	Interrupts: caller dependent.
+ *
+ * @release_port: ``void ()(struct uart_port *port)``
+ *
+ *	Release any memory and IO region resources currently in use by the
+ *	@port.
+ *
+ *	Locking: none.
+ *	Interrupts: caller dependent.
+ *
+ * @request_port: ``int ()(struct uart_port *port)``
+ *
+ *	Request any memory and IO region resources required by the port. If any
+ *	fail, no resources should be registered when this function returns, and
+ *	it should return -%EBUSY on failure.
+ *
+ *	Locking: none.
+ *	Interrupts: caller dependent.
+ *
+ * @config_port: ``void ()(struct uart_port *port, int type)``
+ *
+ *	Perform any autoconfiguration steps required for the @port. @type
+ *	contains a bit mask of the required configuration. %UART_CONFIG_TYPE
+ *	indicates that the port requires detection and identification.
+ *	@port->type should be set to the type found, or %PORT_UNKNOWN if no
+ *	port was detected.
+ *
+ *	%UART_CONFIG_IRQ indicates autoconfiguration of the interrupt signal,
+ *	which should be probed using standard kernel autoprobing techniques.
+ *	This is not necessary on platforms where ports have interrupts
+ *	internally hard wired (eg, system on a chip implementations).
+ *
+ *	Locking: none.
+ *	Interrupts: caller dependent.
+ *
+ * @verify_port: ``int ()(struct uart_port *port,
+ *			struct serial_struct *serinfo)``
+ *
+ *	Verify the new serial port information contained within @serinfo is
+ *	suitable for this port type.
+ *
+ *	Locking: none.
+ *	Interrupts: caller dependent.
+ *
+ * @ioctl: ``int ()(struct uart_port *port, unsigned int cmd,
+ *		unsigned long arg)``
+ *
+ *	Perform any port specific IOCTLs. IOCTL commands must be defined using
+ *	the standard numbering system found in <asm/ioctl.h>.
+ *
+ *	Locking: none.
+ *	Interrupts: caller dependent.
+ *
+ * @poll_init: ``int ()(struct uart_port *port)``
+ *
+ *	Called by kgdb to perform the minimal hardware initialization needed to
+ *	support @poll_put_char() and @poll_get_char(). Unlike @startup(), this
+ *	should not request interrupts.
+ *
+ *	Locking: %tty_mutex and tty_port->mutex taken.
+ *	Interrupts: n/a.
+ *
+ * @poll_put_char: ``void ()(struct uart_port *port, unsigned char ch)``
+ *
+ *	Called by kgdb to write a single character @ch directly to the serial
+ *	@port. It can and should block until there is space in the TX FIFO.
+ *
+ *	Locking: none.
+ *	Interrupts: caller dependent.
+ *	This call must not sleep
+ *
+ * @poll_get_char: ``int ()(struct uart_port *port)``
+ *
+ *	Called by kgdb to read a single character directly from the serial
+ *	port. If data is available, it should be returned; otherwise the

-/* The interface for checksum offload between the stack and networking drivers
+/**
+ * DOC: skb checksums
+ *
+ * The interface for checksum offload between the stack and networking drivers
  * is as follows...
  *
- * A. IP checksum related features
+ * IP checksum related features
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  *
  * Drivers advertise checksum offload capabilities in the features of a device.
  * From the stack's point of view these are capabilities offered by the driver.
  * A driver typically only advertises features that it is capable of offloading
  * to its device.
  *
- * The checksum related features are:
- *
- *	NETIF_F_HW_CSUM	- The driver (or its device) is able to compute one
- *			  IP (one's complement) checksum for any combination
- *			  of protocols or protocol layering. The checksum is
- *			  computed and set in a packet per the CHECKSUM_PARTIAL
- *			  interface (see below).
- *
- *	NETIF_F_IP_CSUM - Driver (device) is only able to checksum plain
- *			  TCP or UDP packets over IPv4. These are specifically
- *			  unencapsulated packets of the form IPv4|TCP or
- *			  IPv4|UDP where the Protocol field in the IPv4 header
- *			  is TCP or UDP. The IPv4 header may contain IP options.
- *			  This feature cannot be set in features for a device
- *			  with NETIF_F_HW_CSUM also set. This feature is being
- *			  DEPRECATED (see below).
- *
- *	NETIF_F_IPV6_CSUM - Driver (device) is only able to checksum plain
- *			  TCP or UDP packets over IPv6. These are specifically
- *			  unencapsulated packets of the form IPv6|TCP or
- *			  IPv6|UDP where the Next Header field in the IPv6
- *			  header is either TCP or UDP. IPv6 extension headers
- *			  are not supported with this feature. This feature
- *			  cannot be set in features for a device with
- *			  NETIF_F_HW_CSUM also set. This feature is being
- *			  DEPRECATED (see below).
- *
- *	NETIF_F_RXCSUM - Driver (device) performs receive checksum offload.
- *			 This flag is only used to disable the RX checksum
- *			 feature for a device. The stack will accept receive
- *			 checksum indication in packets received on a device
- *			 regardless of whether NETIF_F_RXCSUM is set.
- *
- * B. Checksumming of received packets by device. Indication of checksum
- *    verification is set in skb->ip_summed. Possible values are:
- *
- * CHECKSUM_NONE:
+ * .. flat-table:: Checksum related device features
+ *   :widths: 1 10
+ *
+ *   * - %NETIF_F_HW_CSUM
+ *     - The driver (or its device) is able to compute one
+ *	 IP (one's complement) checksum for any combination
+ *	 of protocols or protocol layering. The checksum is
+ *	 computed and set in a packet per the CHECKSUM_PARTIAL
+ *	 interface (see below).
+ *
+ *   * - %NETIF_F_IP_CSUM
+ *     - Driver (device) is only able to checksum plain
+ *	 TCP or UDP packets over IPv4. These are specifically
+ *	 unencapsulated packets of the form IPv4|TCP or
+ *	 IPv4|UDP where the Protocol field in the IPv4 header
+ *	 is TCP or UDP. The IPv4 header may contain IP options.
+ *	 This feature cannot be set in features for a device
+ *	 with NETIF_F_HW_CSUM also set. This feature is being
+ *	 DEPRECATED (see below).
+ *
+ *   * - %NETIF_F_IPV6_CSUM
+ *     - Driver (device) is only able to checksum plain
+ *	 TCP or UDP packets over IPv6. These are specifically
+ *	 unencapsulated packets of the form IPv6|TCP or
+ *	 IPv6|UDP where the Next Header field in the IPv6
+ *	 header is either TCP or UDP. IPv6 extension headers
+ *	 are not supported with this feature. This feature
+ *	 cannot be set in features for a device with
+ *	 NETIF_F_HW_CSUM also set. This feature is being
+ *	 DEPRECATED (see below).
+ *
+ *   * - %NETIF_F_RXCSUM
+ *     - Driver (device) performs receive checksum offload.
+ *	 This flag is only used to disable the RX checksum
+ *	 feature for a device. The stack will accept receive
+ *	 checksum indication in packets received on a device
+ *	 regardless of whether NETIF_F_RXCSUM is set.
+ *
+ * Checksumming of received packets by device
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * Indication of checksum verification is set in &sk_buff.ip_summed.
+ * Possible values are:
+ *
+ * - %CHECKSUM_NONE
  *
  *   Device did not checksum this packet e.g. due to lack of capabilities.
  *   The packet contains full (though not verified) checksum in packet but
  *   not in skb->csum. Thus, skb->csum is undefined in this case.
  *
- * CHECKSUM_UNNECESSARY:
+ * - %CHECKSUM_UNNECESSARY
  *
  *   The hardware you're dealing with doesn't calculate the full checksum
- *   (as in CHECKSUM_COMPLETE), but it does parse headers and verify checksums
- *   for specific protocols. For such packets it will set CHECKSUM_UNNECESSARY
- *   if their checksums are okay. skb->csum is still undefined in this case
+ *   (as in %CHECKSUM_COMPLETE), but it does parse headers and verify checksums
+ *   for specific protocols. For such packets it will set %CHECKSUM_UNNECESSARY
+ *   if their checksums are okay. &sk_buff.csum is still undefined in this case
  *   though. A driver or device must never modify the checksum field in the

- * Tracing hooks
- *
- * Copyright (C) 2008-2009 Red Hat, Inc.  All rights reserved.
- *
- * This file defines hook entry points called by core code where
- * user tracing/debugging support might need to do something.  These
- * entry points are called tracehook_*().  Each hook declared below
- * has a detailed kerneldoc comment giving the context (locking et
- * al) from which it is called, and the meaning of its return value.
- *
- * Each function here typically has only one call site, so it is ok
- * to have some nontrivial tracehook_*() inlines.  In all cases, the
- * fast path when no tracing is enabled should be very short.
- *
- * The purpose of this file and the tracehook_* layer is to consolidate
- * the interface that the kernel core and arch code uses to enable any
- * user debugging or tracing facility (such as ptrace).  The interfaces
- * here are carefully documented so that maintainers of core and arch
- * code do not need to think about the implementation details of the
- * tracing facilities.  Likewise, maintainers of the tracing code do not
- * need to understand all the calling core or arch code in detail, just
- * documented circumstances of each call, such as locking conditions.
- *
- * If the calling core code changes so that locking is different, then
- * it is ok to change the interface documented here.  The maintainer of
- * core code changing should notify the maintainers of the tracing code
- * that they need to work out the change.
- *
- * Some tracehook_*() inlines take arguments that the current tracing
- * implementations might not necessarily use.  These function signatures
- * are chosen to pass in all the information that is on hand in the
- * caller and might conceivably be relevant to a tracer, so that the
- * core code won't have to be updated when tracing adds more features.
- * If a call site changes so that some of those parameters are no longer
- * already on hand without extra work, then the tracehook_* interface
- * can change so there is no make-work burden on the core code.  The
- * maintainer of core code changing should notify the maintainers of the
- * tracing code that they need to work out the change.

+/**
+ * DOC: TTY Driver Flags
+ *
+ * TTY_DRIVER_RESET_TERMIOS
+ *	Requests the tty layer to reset the termios setting when the last
+ *	process has closed the device. Used for PTYs, in particular.
+ *
+ * TTY_DRIVER_REAL_RAW
+ *	Indicates that the driver will guarantee not to set any special
+ *	character handling flags if this is set for the tty:
+ *
+ *	``(IGNBRK || (!BRKINT && !PARMRK)) && (IGNPAR || !INPCK)``
+ *
+ *	That is, if there is no reason for the driver to
+ *	send notifications of parity and break characters up to the line
+ *	driver, it won't do so.  This allows the line driver to optimize for
+ *	this case if this flag is set.  (Note that there is also a promise, if
+ *	the above case is true, not to signal overruns, either.)
+ *
+ * TTY_DRIVER_DYNAMIC_DEV
+ *	The individual tty devices need to be registered with a call to
+ *	tty_register_device() when the device is found in the system and
+ *	unregistered with a call to tty_unregister_device() so the devices will
+ *	be show up properly in sysfs.  If not set, all &tty_driver.num entries
+ *	will be created by the tty core in sysfs when tty_register_driver() is
+ *	called.  This is to be used by drivers that have tty devices that can
+ *	appear and disappear while the main tty driver is registered with the
+ *	tty core.
+ *
+ * TTY_DRIVER_DEVPTS_MEM
+ *	Don't use the standard arrays (&tty_driver.ttys and
+ *	&tty_driver.termios), instead use dynamic memory keyed through the
+ *	devpts filesystem. This is only applicable to the PTY driver.
+ *
+ * TTY_DRIVER_HARDWARE_BREAK
+ *	Hardware handles break signals. Pass the requested timeout to the
+ *	&tty_operations.break_ctl instead of using a simple on/off interface.
+ *
+ * TTY_DRIVER_DYNAMIC_ALLOC
+ *	Do not allocate structures which are needed per line for this driver
+ *	(&tty_driver.ports) as it would waste memory. The driver will take
+ *	care. This is only applicable to the PTY driver.
+ *
+ * TTY_DRIVER_UNNUMBERED_NODE
+ *	Do not create numbered ``/dev`` nodes. For example, create
+ *	``/dev/ttyprintk`` and not ``/dev/ttyprintk0``. Applicable only when a
+ *	driver for a single tty device is being allocated.

- * The dn_dev_parms structure contains the set of parameters
- * for each device (hence inclusion in the dn_dev structure)
- * and an array is used to store the default types of supported
- * device (in dn_dev.c).
- *
- * The type field matches the ARPHRD_ constants and is used in
- * searching the list for supported devices when new devices
- * come up.
- *
- * The mode field is used to find out if a device is broadcast,
- * multipoint, or pointopoint. Please note that DECnet thinks
- * different ways about devices to the rest of the kernel
- * so the normal IFF_xxx flags are invalid here. For devices
- * which can be any combination of the previously mentioned
- * attributes, you can set this on a per device basis by
- * installing an up() routine.
- *
- * The device state field, defines the initial state in which the
- * device will come up. In the dn_dev structure, it is the actual
- * state.
- *
- * Things have changed here. I've killed timer1 since it's a user space
- * issue for a user space routing deamon to sort out. The kernel does
- * not need to be bothered with it.
- *
- * Timers:

+ * struct drm_mode_fb_cmd2 - Frame-buffer metadata.
+ *
+ * This struct holds frame-buffer metadata. There are two ways to use it:
+ *
+ * - User-space can fill this struct and perform a &DRM_IOCTL_MODE_ADDFB2
+ *   ioctl to register a new frame-buffer. The new frame-buffer object ID will
+ *   be set by the kernel in @fb_id.
+ * - User-space can set @fb_id and perform a &DRM_IOCTL_MODE_GETFB2 ioctl to
+ *   fetch metadata about an existing frame-buffer.
+ *
+ * In case of planar formats, this struct allows up to 4 buffer objects with
+ * offsets and pitches per plane. The pitch and offset order are dictated by
+ * the format FourCC as defined by ``drm_fourcc.h``, e.g. NV12 is described as:
+ *
+ *     YUV 4:2:0 image with a plane of 8-bit Y samples followed by an
+ *     interleaved U/V plane containing 8-bit 2x2 subsampled colour difference
+ *     samples.
+ *
+ * So it would consist of a Y plane at ``offsets[0]`` and a UV plane at
+ * ``offsets[1]``.
+ *
+ * To accommodate tiled, compressed, etc formats, a modifier can be specified.
+ * For more information see the "Format Modifiers" section. Note that even
+ * though it looks like we have a modifier per-plane, we in fact do not. The
+ * modifier for each plane must be identical. Thus all combinations of
+ * different data layouts for multi-plane formats must be enumerated as
+ * separate modifiers.
+ *
+ * All of the entries in @handles, @pitches, @offsets and @modifier must be
+ * zero when unused. Warning, for @offsets and @modifier zero can't be used to
+ * figure out whether the entry is used or not since it's a valid value (a zero
+ * offset is common, and a zero modifier is &DRM_FORMAT_MOD_LINEAR).

+	 * that can *only* be placed in I915_MEMORY_CLASS_DEVICE, we therefore
+	 * don't support I915_GEM_CREATE_EXT_FLAG_NEEDS_CPU_ACCESS together with
+	 * flat-CCS.
+	 *
+	 * Without this hint, the kernel will assume that non-mappable
+	 * I915_MEMORY_CLASS_DEVICE is preferred for this object. Note that the
+	 * kernel can still migrate the object to the mappable part, as a last
+	 * resort, if userspace ever CPU faults this object, but this might be
+	 * expensive, and so ideally should be avoided.
+	 *
+	 * On older kernels which lack the relevant small-bar uAPI support (see
+	 * also &drm_i915_memory_region_info.probed_cpu_visible_size),
+	 * usage of the flag will result in an error, but it should NEVER be

+ *		long (\*callback_fn)(struct bpf_dynptr \*dynptr, void \*ctx);
+ *
+ *		If **callback_fn** returns 0, the helper will continue to try

+ *		draining samples, or 0 if no samples were present in the ring
+ *		buffer. If a user-space producer was epoll-waiting on this map,
+ *		and at least one sample was drained, they will receive an event
+ *		notification notifying them of available space in the ring
+ *		buffer. If the BPF_RB_NO_WAKEUP flag is passed to this

+ *		**-EBUSY** if the ring buffer is contended, and another calling
+ *		context was concurrently draining the ring buffer.
+ *
+ *		**-EINVAL** if user-space is not properly tracking the ring
+ *		buffer due to the producer position not being aligned to 8
+ *		bytes, a sample not being aligned to 8 bytes, or the producer
+ *		position not matching the advertised length of a sample.
+ *
+ *		**-E2BIG** if user-space has tried to publish a sample which is
+ *		larger than the size of the ring buffer, or which cannot fit
+ *		within a struct bpf_dynptr.

+ *
+ * NOTE ABOUT THE CHOICE OF NAMES HERE AND THE CAMELSCRIPT:
+ *   The choice to use CamelScript and the exact names below is for
+ *   maintainability, clarity, similarity to manufacturer's documentation,
+ *   _and_ a mitigation for confusion that has plagued the use of these drivers
+ *   for years!
+ *
+ *   More detail:
+ *   There have been significant confusions over the past many years for users
+ *   when trying to understand how to connect to/from signals and terminals on
+ *   NI hardware using comedi.  The major reason for this is that the actual
+ *   register values were exposed and required to be used by users.  Several
+ *   major reasons exist why this caused major confusion for users:
+ *   1) The register values are _NOT_ in user documentation, but rather in
+ *     arcane locations, such as a few register programming manuals that are
+ *     increasingly hard to find and the NI MHDDK (comments in example code).
+ *     There is no one place to find the various valid values of the registers.
+ *   2) The register values are _NOT_ completely consistent.  There is no way to
+ *     gain any sense of intuition of which values, or even enums one should use
+ *     for various registers.  There was some attempt in prior use of comedi to
+ *     name enums such that a user might know which enums should be used for
+ *     varying purposes, but the end-user had to gain a knowledge of register
+ *     values to correctly wield this approach.
+ *   3) The names for signals and registers found in the various register level
+ *     programming manuals and vendor-provided documentation are _not_ even
+ *     close to the same names that are in the end-user documentation.
+ *
+ *   Similar, albeit less, confusion plagued NI's previous version of their own
+ *   drivers.  Earlier than 2003, NI greatly simplified the situation for users
+ *   by releasing a new API that abstracted the names of signals/terminals to a
+ *   common and intuitive set of names.
+ *
+ *   The names below mirror the names chosen and well documented by NI.  These
+ *   names are exposed to the user via the comedilib user library.  By keeping
+ *   the names below, in spite of the use of CamelScript, maintenance will be
+ *   greatly eased and confusion for users _and_ comedi developers will be
+ *   greatly reduced.

+ * struct dma_buf_export_sync_file - Get a sync_file from a dma-buf
+ *
+ * Userspace can perform a DMA_BUF_IOCTL_EXPORT_SYNC_FILE to retrieve the
+ * current set of fences on a dma-buf file descriptor as a sync_file.  CPU
+ * waits via poll() or other driver-specific mechanisms typically wait on
+ * whatever fences are on the dma-buf at the time the wait begins.  This
+ * is similar except that it takes a snapshot of the current fences on the
+ * dma-buf for waiting later instead of waiting immediately.  This is
+ * useful for modern graphics APIs such as Vulkan which assume an explicit
+ * synchronization model but still need to inter-operate with dma-buf.
+ *
+ * The intended usage pattern is the following:
+ *
+ *  1. Export a sync_file with flags corresponding to the expected GPU usage
+ *     via DMA_BUF_IOCTL_EXPORT_SYNC_FILE.
+ *
+ *  2. Submit rendering work which uses the dma-buf.  The work should wait on
+ *     the exported sync file before rendering and produce another sync_file
+ *     when complete.
+ *
+ *  3. Import the rendering-complete sync_file into the dma-buf with flags
+ *     corresponding to the GPU usage via DMA_BUF_IOCTL_IMPORT_SYNC_FILE.
+ *
+ * Unlike doing implicit synchronization via a GPU kernel driver's exec ioctl,
+ * the above is not a single atomic operation.  If userspace wants to ensure
+ * ordering via these fences, it is the respnosibility of userspace to use
+ * locks or other mechanisms to ensure that no other context adds fences or
+ * submits work between steps 1 and 3 above.

- * device_state: (read/write)
- *      - The user application writes to this field to inform the vendor driver
- *        about the device state to be transitioned to.
- *      - The vendor driver should take the necessary actions to change the

- *        vendor driver should return success on write(device_state, state)
- *        system call. If the device state transition fails, the vendor driver
- *        should return an appropriate -errno for the fault condition.
- *      - On the user application side, if the device state transition fails,
- *	  that is, if write(device_state, state) returns an error, read
- *	  device_state again to determine the current state of the device from
- *	  the vendor driver.
- *      - The vendor driver should return previous state of the device unless
- *        the vendor driver has encountered an internal error, in which case
- *        the vendor driver may report the device_state VFIO_DEVICE_STATE_ERROR.

- *        indicated to be in a valid device state by reading device_state, the
- *        user application may attempt to transition the device to any valid
- *        state reachable from the current state or terminate itself.
- *
- *      device_state consists of 3 bits:
- *      - If bit 0 is set, it indicates the _RUNNING state. If bit 0 is clear,
- *        it indicates the _STOP state. When the device state is changed to
- *        _STOP, driver should stop the device before write() returns.
- *      - If bit 1 is set, it indicates the _SAVING state, which means that the
- *        driver should start gathering device state information that will be
- *        provided to the VFIO user application to save the device's state.
- *      - If bit 2 is set, it indicates the _RESUMING state, which means that
- *        the driver should prepare to resume the device. Data provided through
- *        the migration region should be used to resume the device.
- *      Bits 3 - 31 are reserved for future use. To preserve them, the user
- *      application should perform a read-modify-write operation on this
- *      field when modifying the specified bits.

- * 0. Default state of VFIO device is _RUNNING when the user application starts.
- * 1. During normal shutdown of the user application, the user application may
- *    optionally change the VFIO device state from _RUNNING to _STOP. This
- *    transition is optional. The vendor driver must support this transition but
- *    must not require it.
- * 2. When the user application saves state or suspends the application, the
- *    device state transitions from _RUNNING to stop-and-copy and then to _STOP.
- *    On state transition from _RUNNING to stop-and-copy, driver must stop the
- *    device, save the device state and send it to the application through the
- *    migration region. The sequence to be followed for such transition is given
- *    below.
- * 3. In live migration of user application, the state transitions from _RUNNING
- *    to pre-copy, to stop-and-copy, and to _STOP.
- *    On state transition from _RUNNING to pre-copy, the driver should start
- *    gathering the device state while the application is still running and send
- *    the device state data to application through the migration region.
- *    On state transition from pre-copy to stop-and-copy, the driver must stop
- *    the device, save the device state and send it to the user application
- *    through the migration region.
- *    Vendor drivers must support the pre-copy state even for implementations
- *    where no data is provided to the user before the stop-and-copy state. The
- *    user must not be required to consume all migration data before the device
- *    transitions to a new state, including the stop-and-copy state.
- *    The sequence to be followed for above two transitions is given below.
- * 4. To start the resuming phase, the device state should be transitioned from
- *    the _RUNNING to the _RESUMING state.
- *    In the _RESUMING state, the driver should use the device state data
- *    received through the migration region to resume the device.
- * 5. After providing saved device data to the driver, the application should
- *    change the state from _RESUMING to _RUNNING.
- *
- * reserved:
- *      Reads on this field return zero and writes are ignored.
- *
- * pending_bytes: (read only)
- *      The number of pending bytes still to be migrated from the vendor driver.
- *
- * data_offset: (read only)
- *      The user application should read data_offset field from the migration
- *      region. The user application should read the device data from this
- *      offset within the migration region during the _SAVING state or write
- *      the device data during the _RESUMING state. See below for details of
- *      sequence to be followed.
- *
- * data_size: (read/write)
- *      The user application should read data_size to get the size in bytes of
- *      the data copied in the migration region during the _SAVING state and
- *      write the size in bytes of the data copied in the migration region
- *      during the _RESUMING state.
- *
- * The format of the migration region is as follows:
- *  ------------------------------------------------------------------
- * |vfio_device_migration_info|    data section                      |
- * |                          |     ///////////////////////////////  |
- * ------------------------------------------------------------------
- *   ^                              ^
- *  offset 0-trapped part        data_offset
- *
- * The structure vfio_device_migration_info is always followed by the data
- * section in the region, so data_offset will always be nonzero. The offset
- * from where the data is copied is decided by the kernel driver. The data
- * section can be trapped, mmapped, or partitioned, depending on how the kernel
- * driver defines the data section. The data section partition can be defined
- * as mapped by the sparse mmap capability. If mmapped, data_offset must be
- * page aligned, whereas initial section which contains the
- * vfio_device_migration_info structure, might not end at the offset, which is
- * page aligned. The user is not required to access through mmap regardless
- * of the capabilities of the region mmap.
- * The vendor driver should determine whether and how to partition the data
- * section. The vendor driver should return data_offset accordingly.
- *
- * The sequence to be followed while in pre-copy state and stop-and-copy state
- * is as follows:
- * a. Read pending_bytes, indicating the start of a new iteration to get device
- *    data. Repeated read on pending_bytes at this stage should have no side
- *    effects.
- *    If pending_bytes == 0, the user application should not iterate to get data
- *    for that device.
- *    If pending_bytes > 0, perform the following steps.
- * b. Read data_offset, indicating that the vendor driver should make data
- *    available through the data section. The vendor driver should return this
- *    read operation only after data is available from (region + data_offset)
- *    to (region + data_offset + data_size).
- * c. Read data_size, which is the amount of data in bytes available through
- *    the migration region.
- *    Read on data_offset and data_size should return the offset and size of
- *    the current buffer if the user application reads data_offset and
- *    data_size more than once here.
- * d. Read data_size bytes of data from (region + data_offset) from the
- *    migration region.
- * e. Process the data.
- * f. Read pending_bytes, which indicates that the data from the previous
- *    iteration has been read. If pending_bytes > 0, go to step b.
- *
- * The user application can transition from the _SAVING|_RUNNING
- * (pre-copy state) to the _SAVING (stop-and-copy) state regardless of the
- * number of pending bytes. The user application should iterate in _SAVING
- * (stop-and-copy) until pending_bytes is 0.
- *
- * The sequence to be followed while _RESUMING device state is as follows:
- * While data for this device is available, repeat the following steps:
- * a. Read data_offset from where the user application should write data.
- * b. Write migration data starting at the migration region + data_offset for
- *    the length determined by data_size from the migration source.
- * c. Write data_size, which indicates to the vendor driver that data is
- *    written in the migration region. Vendor driver must return this write
- *    operations on consuming data. Vendor driver should apply the
- *    user-provided migration region data to the device resume state.
- *
- * If an error occurs during the above sequences, the vendor driver can return
- * an error code for next read() or write() operation, which will terminate the
- * loop. The user application should then take the next necessary action, for
- * example, failing migration or terminating the user application.
- *
- * For the user application, data is opaque. The user application should write
- * data in the same order as the data is received and the data should be of
- * same transaction size at the source.

+ * The device migration Finite State Machine is described by the enum
+ * vfio_device_mig_state. Some of the FSM arcs will create a migration data
+ * transfer session by returning a FD, in this case the migration data will
+ * flow over the FD using read() and write() as discussed below.
+ *
+ * There are 5 states to support VFIO_MIGRATION_STOP_COPY:
+ *  RUNNING - The device is running normally
+ *  STOP - The device does not change the internal or external state
+ *  STOP_COPY - The device internal state can be read out
+ *  RESUMING - The device is stopped and is loading a new internal state
+ *  ERROR - The device has failed and must be reset
+ *
+ * And 1 optional state to support VFIO_MIGRATION_P2P:
+ *  RUNNING_P2P - RUNNING, except the device cannot do peer to peer DMA
+ *
+ * The FSM takes actions on the arcs between FSM states. The driver implements
+ * the following behavior for the FSM arcs:
+ *
+ * RUNNING_P2P -> STOP
+ * STOP_COPY -> STOP
+ *   While in STOP the device must stop the operation of the device. The device
+ *   must not generate interrupts, DMA, or any other change to external state.
+ *   It must not change its internal state. When stopped the device and kernel
+ *   migration driver must accept and respond to interaction to support external
+ *   subsystems in the STOP state, for example PCI MSI-X and PCI config space.
+ *   Failure by the user to restrict device access while in STOP must not result
+ *   in error conditions outside the user context (ex. host system faults).
+ *
+ *   The STOP_COPY arc will terminate a data transfer session.
+ *
+ * RESUMING -> STOP
+ *   Leaving RESUMING terminates a data transfer session and indicates the
+ *   device should complete processing of the data delivered by write(). The
+ *   kernel migration driver should complete the incorporation of data written
+ *   to the data transfer FD into the device internal state and perform
+ *   final validity and consistency checking of the new device state. If the
+ *   user provided data is found to be incomplete, inconsistent, or otherwise
+ *   invalid, the migration driver must fail the SET_STATE ioctl and
+ *   optionally go to the ERROR state as described below.
+ *
+ *   While in STOP the device has the same behavior as other STOP states
+ *   described above.
+ *
+ *   To abort a RESUMING session the device must be reset.
+ *
+ * RUNNING_P2P -> RUNNING
+ *   While in RUNNING the device is fully operational, the device may generate
+ *   interrupts, DMA, respond to MMIO, all vfio device regions are functional,
+ *   and the device may advance its internal state.
+ *
+ * RUNNING -> RUNNING_P2P
+ * STOP -> RUNNING_P2P
+ *   While in RUNNING_P2P the device is partially running in the P2P quiescent
+ *   state defined below.
+ *
+ * STOP -> STOP_COPY
+ *   This arc begin the process of saving the device state and will return a
+ *   new data_fd.
+ *
+ *   While in the STOP_COPY state the device has the same behavior as STOP
+ *   with the addition that the data transfers session continues to stream the
+ *   migration state. End of stream on the FD indicates the entire device
+ *   state has been transferred.
+ *
+ *   The user should take steps to restrict access to vfio device regions while
+ *   the device is in STOP_COPY or risk corruption of the device migration data
+ *   stream.
+ *
+ * STOP -> RESUMING
+ *   Entering the RESUMING state starts a process of restoring the device state
+ *   and will return a new data_fd. The data stream fed into the data_fd should
+ *   be taken from the data transfer output of a single FD during saving from
+ *   a compatible device. The migration driver may alter/reset the internal
+ *   device state for this arc if required to prepare the device to receive the
+ *   migration data.
+ *
+ * any -> ERROR
+ *   ERROR cannot be specified as a device state, however any transition request
+ *   can be failed with an errno return and may then move the device_state into
+ *   ERROR. In this case the device was unable to execute the requested arc and
+ *   was also unable to restore the device to any valid device_state.
+ *   To recover from ERROR VFIO_DEVICE_RESET must be used to return the
+ *   device_state back to RUNNING.
+ *
+ * The optional peer to peer (P2P) quiescent state is intended to be a quiescent
+ * state for the device for the purposes of managing multiple devices within a
+ * user context where peer-to-peer DMA between devices may be active. The
+ * RUNNING_P2P states must prevent the device from initiating
+ * any new P2P DMA transactions. If the device can identify P2P transactions
+ * then it can stop only P2P DMA, otherwise it must stop all DMA. The migration
+ * driver must complete any such outstanding operations prior to completing the
+ * FSM arc into a P2P state. For the purpose of specification the states
+ * behave as though the device was fully running if not supported. Like while in
+ * STOP or STOP_COPY the user must not touch the device, otherwise the state
+ * can be exited.
+ *
+ * The remaining possible transitions are interpreted as combinations of the
+ * above FSM arcs. As there are multiple paths through the FSM arcs the path
+ * should be selected based on the following rules:
+ *   - Select the shortest path.
+ * Refer to vfio_mig_get_next_state() for the result of the algorithm.
+ *
+ * The automatic transit through the FSM arcs that make up the combination
+ * transition is invisible to the user. When working with combination arcs the
+ * user may see any step along the path in the device_state if SET_STATE
+ * fails. When handling these types of errors users should anticipate future
+ * revisions of this protocol using new states and those states becoming
+ * visible in this case.
+ *
+ * The optional states cannot be used with SET_STATE if the device does not
+ * support them. The user can discover if these states are supported by using
+ * VFIO_DEVICE_FEATURE_MIGRATION. By using combination transitions the user can
+ * avoid knowing about these optional states if the kernel driver supports them.

+/*
+ * Detailed Interface Description
+ * ==============================
+ * The pvUSB interface is using a split driver design: a frontend driver in
+ * the guest and a backend driver in a driver domain (normally dom0) having
+ * access to the physical USB device(s) being passed to the guest.
+ *
+ * The frontend and backend drivers use XenStore to initiate the connection
+ * between them, the I/O activity is handled via two shared ring pages and an
+ * event channel. As the interface between frontend and backend is at the USB
+ * host connector level, multiple (up to 31) physical USB devices can be
+ * handled by a single connection.
+ *
+ * The Xen pvUSB device name is "qusb", so the frontend's XenStore entries are
+ * to be found under "device/qusb", while the backend's XenStore entries are
+ * under "backend/<guest-dom-id>/qusb".
+ *
+ * When a new pvUSB connection is established, the frontend needs to setup the
+ * two shared ring pages for communication and the event channel. The ring
+ * pages need to be made available to the backend via the grant table
+ * interface.
+ *
+ * One of the shared ring pages is used by the backend to inform the frontend
+ * about USB device plug events (device to be added or removed). This is the
+ * "conn-ring".
+ *
+ * The other ring page is used for USB I/O communication (requests and
+ * responses). This is the "urb-ring".
+ *
+ * Feature and Parameter Negotiation
+ * =================================
+ * The two halves of a Xen pvUSB driver utilize nodes within the XenStore to
+ * communicate capabilities and to negotiate operating parameters. This
+ * section enumerates these nodes which reside in the respective front and
+ * backend portions of the XenStore, following the XenBus convention.
+ *
+ * Any specified default value is in effect if the corresponding XenBus node
+ * is not present in the XenStore.
+ *
+ * XenStore nodes in sections marked "PRIVATE" are solely for use by the
+ * driver side whose XenBus tree contains them.

+ *
+ * USB device plug events are send via the "conn-ring" shared page. As only

+ * +----------------+----------------+----------------+----------------+
+ *   id - uint16_t, event id (taken from the actual frontend dummy request)
+ *   portnum - uint8_t, port number (1 ... 31)
+ *   speed - uint8_t, device XENUSB_SPEED_*, XENUSB_SPEED_NONE == unplug
+ *
+ * The dummy request:

+ * Xenstore format in practice
+ * ===========================
+ *
+ * The backend driver uses a single_host:many_devices notation to manage domU
+ * devices. Everything is stored in /local/domain/<backend_domid>/backend/vscsi/.
+ * The xenstore layout looks like this (dom0 is assumed to be the backend_domid):
+ *
+ *     <domid>/<vhost>/feature-host = "0"
+ *     <domid>/<vhost>/frontend = "/local/domain/<domid>/device/vscsi/0"
+ *     <domid>/<vhost>/frontend-id = "<domid>"
+ *     <domid>/<vhost>/online = "1"
+ *     <domid>/<vhost>/state = "4"
+ *     <domid>/<vhost>/vscsi-devs/dev-0/p-dev = "8:0:2:1" or "naa.wwn:lun"
+ *     <domid>/<vhost>/vscsi-devs/dev-0/state = "4"
+ *     <domid>/<vhost>/vscsi-devs/dev-0/v-dev = "0:0:0:0"

+ *     <domid>/<vhost>/vscsi-devs/dev-1/v-dev = "0:0:1:0"
+ *
+ * The frontend driver maintains its state in
+ * /local/domain/<domid>/device/vscsi/.
+ *
+ *     <vhost>/backend = "/local/domain/0/backend/vscsi/<domid>/<vhost>"

+ *     <vhost>/vscsi-devs/dev-1/state = "4"
+ *
+ * In addition to the entries for backend and frontend these flags are stored
+ * for the toolstack:
+ *
+ *     <domid>/<vhost>/vscsi-devs/dev-1/p-devname = "/dev/$device"

+ * Wait for <domid>/<vhost>/state + <domid>/<vhost>/vscsi-devs/dev-0/state become 4
+ *
