- * struct gpio_chip - abstract a GPIO controller
- * @label: for diagnostics

- * @request: optional hook for chip-specific activation, such as
- *	enabling module power and clock; may sleep
- * @free: optional hook for chip-specific deactivation, such as
- *	disabling module power and clock; may sleep
- * @get_direction: returns direction for signal "offset", 0=out, 1=in,
- *	(same as GPIOF_DIR_XXX), or negative error
- * @direction_input: configures signal "offset" as input, or returns error
- * @get: returns value for signal "offset"; for output signals this
- *	returns either the value actually sensed, or zero
- * @direction_output: configures signal "offset" as output, or returns error
- * @set_debounce: optional hook for setting debounce time for specified gpio in
- *      interrupt triggered gpio chips
- * @set: assigns output value for signal "offset"
- * @to_irq: optional hook supporting non-static gpio_to_irq() mappings;
- *	implementation may not sleep
- * @dbg_show: optional routine to show contents in debugfs; default code
- *	will be used when this is omitted, but custom code can show extra
- *	state (such as pullup/pulldown configuration).
- * @base: identifies the first GPIO number handled by this chip; or, if
- *	negative during registration, requests dynamic ID allocation.
- * @ngpio: the number of GPIOs handled by this controller; the last GPIO
- *	handled is (base + ngpio - 1).
- * @desc: array of ngpio descriptors. Private.
- * @can_sleep: flag must be set iff get()/set() methods sleep, as they
- *	must while accessing GPIO expander chips over I2C or SPI
- * @names: if set, must be an array of strings to use as alternative
- *      names for the GPIOs in this chip. Any entry in the array
- *      may be NULL if there is no alias for the GPIO, however the
- *      array must be @ngpio entries long.  A name can include a single printk
- *      format specifier for an unsigned int.  It is substituted by the actual
- *      number of the gpio.
- *
- * A gpio_chip can help platforms abstract various sources of GPIOs so
- * they can all be accessed through a common programing interface.
- * Example sources would be SOC controllers, FPGAs, multifunction
- * chips, dedicated GPIO expanders, and so on.
- *
- * Each chip controls a number of signals, identified in method calls
- * by "offset" values in the range 0..(@ngpio - 1).  When those signals
- * are referenced through calls like gpio_get_value(gpio), the offset
- * is calculated by subtracting @base from the gpio number.

+ * 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

+/*
+ * Generic MMU-gather implementation.
+ *
+ * The mmu_gather data structure is used by the mm code to implement the
+ * correct and efficient ordering of freeing pages and TLB invalidations.
+ *
+ * This correct ordering is:
+ *
+ *  1) unhook page
+ *  2) TLB invalidate page
+ *  3) free page
+ *
+ * That is, we must never free a page before we have ensured there are no live
+ * translations left to it. Otherwise it might be possible to observe (or
+ * worse, change) the page content after it has been reused.
+ *
+ * The mmu_gather API consists of:
+ *
+ *  - tlb_gather_mmu() / tlb_gather_mmu_fullmm() / tlb_finish_mmu()
+ *
+ *    start and finish a mmu_gather
+ *
+ *    Finish in particular will issue a (final) TLB invalidate and free
+ *    all (remaining) queued pages.
+ *
+ *  - tlb_start_vma() / tlb_end_vma(); marks the start / end of a VMA
+ *
+ *    Defaults to flushing at tlb_end_vma() to reset the range; helps when
+ *    there's large holes between the VMAs.
+ *
+ *  - tlb_remove_table()
+ *
+ *    tlb_remove_table() is the basic primitive to free page-table directories
+ *    (__p*_free_tlb()).  In it's most primitive form it is an alias for
+ *    tlb_remove_page() below, for when page directories are pages and have no
+ *    additional constraints.
+ *
+ *    See also MMU_GATHER_TABLE_FREE and MMU_GATHER_RCU_TABLE_FREE.
+ *
+ *  - tlb_remove_page() / __tlb_remove_page()
+ *  - tlb_remove_page_size() / __tlb_remove_page_size()
+ *
+ *    __tlb_remove_page_size() is the basic primitive that queues a page for
+ *    freeing. __tlb_remove_page() assumes PAGE_SIZE. Both will return a
+ *    boolean indicating if the queue is (now) full and a call to
+ *    tlb_flush_mmu() is required.
+ *
+ *    tlb_remove_page() and tlb_remove_page_size() imply the call to
+ *    tlb_flush_mmu() when required and has no return value.
+ *
+ *  - tlb_change_page_size()
+ *
+ *    call before __tlb_remove_page*() to set the current page-size; implies a
+ *    possible tlb_flush_mmu() call.
+ *
+ *  - tlb_flush_mmu() / tlb_flush_mmu_tlbonly()
+ *
+ *    tlb_flush_mmu_tlbonly() - does the TLB invalidate (and resets
+ *                              related state, like the range)
+ *
+ *    tlb_flush_mmu() - in addition to the above TLB invalidate, also frees
+ *			whatever pages are still batched.
+ *
+ *  - mmu_gather::fullmm
+ *
+ *    A flag set by tlb_gather_mmu_fullmm() to indicate we're going to free
+ *    the entire mm; this allows a number of optimizations.
+ *
+ *    - We can ignore tlb_{start,end}_vma(); because we don't
+ *      care about ranges. Everything will be shot down.
+ *
+ *    - (RISC) architectures that use ASIDs can cycle to a new ASID
+ *      and delay the invalidation until ASID space runs out.
+ *
+ *  - mmu_gather::need_flush_all
+ *
+ *    A flag that can be set by the arch code if it wants to force
+ *    flush the entire TLB irrespective of the range. For instance
+ *    x86-PAE needs this when changing top-level entries.
+ *
+ * And allows the architecture to provide and implement tlb_flush():
+ *
+ * tlb_flush() may, in addition to the above mentioned mmu_gather fields, make
+ * use of:
+ *
+ *  - mmu_gather::start / mmu_gather::end
+ *
+ *    which provides the range that needs to be flushed to cover the pages to
+ *    be freed.
+ *
+ *  - mmu_gather::freed_tables
+ *
+ *    set when we freed page table pages
+ *
+ *  - tlb_get_unmap_shift() / tlb_get_unmap_size()
+ *
+ *    returns the smallest TLB entry size unmapped in this range.
+ *
+ * If an architecture does not provide tlb_flush() a default implementation
+ * based on flush_tlb_range() will be used, unless MMU_GATHER_NO_RANGE is
+ * specified, in which case we'll default to flush_tlb_mm().
+ *
+ * Additionally there are a few opt-in features:
+ *
+ *  MMU_GATHER_PAGE_SIZE
+ *
+ *  This ensures we call tlb_flush() every time tlb_change_page_size() actually
+ *  changes the size and provides mmu_gather::page_size to tlb_flush().
+ *
+ *  This might be useful if your architecture has size specific TLB
+ *  invalidation instructions.
+ *
+ *  MMU_GATHER_TABLE_FREE
+ *
+ *  This provides tlb_remove_table(), to be used instead of tlb_remove_page()
+ *  for page directores (__p*_free_tlb()).
+ *
+ *  Useful if your architecture has non-page page directories.
+ *
+ *  When used, an architecture is expected to provide __tlb_remove_table()
+ *  which does the actual freeing of these pages.
+ *
+ *  MMU_GATHER_RCU_TABLE_FREE
+ *
+ *  Like MMU_GATHER_TABLE_FREE, and adds semi-RCU semantics to the free (see
+ *  comment below).
+ *
+ *  Useful if your architecture doesn't use IPIs for remote TLB invalidates
+ *  and therefore doesn't naturally serialize with software page-table walkers.
  *
- * This is needed by some architectures to implement software pagetable walkers.
+ *  MMU_GATHER_NO_FLUSH_CACHE
  *
- * gup_fast() and other software pagetable walkers do a lockless page-table
- * walk and therefore needs some synchronization with the freeing of the page
- * directories. The chosen means to accomplish that is by disabling IRQs over
- * the walk.
+ *  Indicates the architecture has flush_cache_range() but it needs *NOT* be called
+ *  before unmapping a VMA.
  *
- * Architectures that use IPIs to flush TLBs will then automagically DTRT,
- * since we unlink the page, flush TLBs, free the page. Since the disabling of
- * IRQs delays the completion of the TLB flush we can never observe an already
- * freed page.
+ *  NOTE: strictly speaking we shouldn't have this knob and instead rely on
+ *	  flush_cache_range() being a NOP, except Sparc64 seems to be
+ *	  different here.
  *
- * Architectures that do not have this (PPC) need to delay the freeing by some
- * other means, this is that means.
+ *  MMU_GATHER_MERGE_VMAS
  *
- * What we do is batch the freed directory pages (tables) and RCU free them.
- * We use the sched RCU variant, as that guarantees that IRQ/preempt disabling
- * holds off grace periods.
+ *  Indicates the architecture wants to merge ranges over VMAs; typical when
+ *  multiple range invalidates are more expensive than a full invalidate.
  *
- * However, in order to batch these pages we need to allocate storage, this
- * allocation is deep inside the MM code and can thus easily fail on memory
- * pressure. To guarantee progress we fall back to single table freeing, see
- * the implementation of tlb_remove_table_one().
+ *  MMU_GATHER_NO_RANGE
  *
+ *  Use this if your architecture lacks an efficient flush_tlb_range(). This
+ *  option implies MMU_GATHER_MERGE_VMAS above.
+ *
+ *  MMU_GATHER_NO_GATHER
+ *
+ *  If the option is set the mmu_gather will not track individual pages for
+ *  delayed page free anymore. A platform that enables the option needs to
+ *  provide its own implementation of the __tlb_remove_page_size() function to
+ *  free pages.
+ *
+ *  This is useful if your architecture already flushes TLB entries in the
+ *  various ptep_get_and_clear() functions.

+/**
+ * DOC: Authenticated Encryption With Associated Data (AEAD) Cipher API
+ *
+ * The AEAD cipher API is used with the ciphers of type CRYPTO_ALG_TYPE_AEAD
+ * (listed as type "aead" in /proc/crypto)
+ *
+ * The most prominent examples for this type of encryption is GCM and CCM.
+ * However, the kernel supports other types of AEAD ciphers which are defined
+ * with the following cipher string:
+ *
+ *	authenc(keyed message digest, block cipher)
+ *
+ * For example: authenc(hmac(sha256), cbc(aes))
+ *
+ * The example code provided for the symmetric key cipher operation applies
+ * here as well. Naturally all *skcipher* symbols must be exchanged the *aead*
+ * pendants discussed in the following. In addition, for the AEAD operation,
+ * the aead_request_set_ad function must be used to set the pointer to the
+ * associated data memory location before performing the encryption or
+ * decryption operation. Another deviation from the asynchronous block cipher
+ * operation is that the caller should explicitly check for -EBADMSG of the
+ * crypto_aead_decrypt. That error indicates an authentication error, i.e.
+ * a breach in the integrity of the message. In essence, that -EBADMSG error
+ * code is the key bonus an AEAD cipher has over "standard" block chaining
+ * modes.
+ *
+ * Memory Structure:
+ *
+ * The source scatterlist must contain the concatenation of
+ * associated data || plaintext or ciphertext.
+ *
+ * The destination scatterlist has the same layout, except that the plaintext
+ * (resp. ciphertext) will grow (resp. shrink) by the authentication tag size
+ * during encryption (resp. decryption). The authentication tag is generated
+ * during the encryption operation and appended to the ciphertext. During
+ * decryption, the authentication tag is consumed along with the ciphertext and
+ * used to verify the integrity of the plaintext and the associated data.
+ *
+ * In-place encryption/decryption is enabled by using the same scatterlist
+ * pointer for both the source and destination.
+ *
+ * Even in the out-of-place case, space must be reserved in the destination for
+ * the associated data, even though it won't be written to.  This makes the
+ * in-place and out-of-place cases more consistent.  It is permissible for the
+ * "destination" associated data to alias the "source" associated data.
+ *
+ * As with the other scatterlist crypto APIs, zero-length scatterlist elements
+ * are not allowed in the used part of the scatterlist.  Thus, if there is no
+ * associated data, the first element must point to the plaintext/ciphertext.
+ *
+ * To meet the needs of IPsec, a special quirk applies to rfc4106, rfc4309,
+ * rfc4543, and rfc7539esp ciphers.  For these ciphers, the final 'ivsize' bytes
+ * of the associated data buffer must contain a second copy of the IV.  This is
+ * in addition to the copy passed to aead_request_set_crypt().  These two IV
+ * copies must not differ; different implementations of the same algorithm may
+ * behave differently in that case.  Note that the algorithm might not actually
+ * treat the IV as associated data; nevertheless the length passed to
+ * aead_request_set_ad() must include it.

+ * @init: **[mandatory]** Initialize the transformation context. Intended only to initialize the
+ *	  state of the HASH transformation at the beginning. This shall fill in
+ *	  the internal structures used during the entire duration of the whole
+ *	  transformation. No data processing happens at this point. Driver code
+ *	  implementation must not use req->result.
+ * @update: **[mandatory]** Push a chunk of data into the driver for transformation. This
+ *	   function actually pushes blocks of data from upper layers into the
+ *	   driver, which then passes those to the hardware as seen fit. This
+ *	   function must not finalize the HASH transformation by calculating the
+ *	   final message digest as this only adds more data into the
+ *	   transformation. This function shall not modify the transformation
+ *	   context, as this function may be called in parallel with the same
+ *	   transformation object. Data processing can happen synchronously
+ *	   [SHASH] or asynchronously [AHASH] at this point. Driver must not use
+ *	   req->result.
+ * @final: **[mandatory]** Retrieve result from the driver. This function finalizes the
+ *	   transformation and retrieves the resulting hash from the driver and
+ *	   pushes it back to upper layers. No data processing happens at this
+ *	   point unless hardware requires it to finish the transformation
+ *	   (then the data buffered by the device driver is processed).
+ * @finup: **[optional]** Combination of @update and @final. This function is effectively a
+ *	   combination of @update and @final calls issued in sequence. As some
+ *	   hardware cannot do @update and @final separately, this callback was
+ *	   added to allow such hardware to be used at least by IPsec. Data
+ *	   processing can happen synchronously [SHASH] or asynchronously [AHASH]
+ *	   at this point.
+ * @digest: Combination of @init and @update and @final. This function
+ *	    effectively behaves as the entire chain of operations, @init,
+ *	    @update and @final issued in sequence. Just like @finup, this was
+ *	    added for hardware which cannot do even the @finup, but can only do
+ *	    the whole transformation in one run. Data processing can happen
+ *	    synchronously [SHASH] or asynchronously [AHASH] at this point.
+ * @setkey: Set optional key used by the hashing algorithm. Intended to push
+ *	    optional key used by the hashing algorithm from upper layers into
+ *	    the driver. This function can store the key in the transformation
+ *	    context or can outright program it into the hardware. In the former
+ *	    case, one must be careful to program the key into the hardware at
+ *	    appropriate time and one must be careful that .setkey() can be
+ *	    called multiple times during the existence of the transformation
+ *	    object. Not  all hashing algorithms do implement this function as it
+ *	    is only needed for keyed message digests. SHAx/MDx/CRCx do NOT
+ *	    implement this function. HMAC(MDx)/HMAC(SHAx)/CMAC(AES) do implement
+ *	    this function. This function must be called before any other of the
+ *	    @init, @update, @final, @finup, @digest is called. No data
+ *	    processing happens at this point.
+ * @export: Export partial state of the transformation. This function dumps the
+ *	    entire state of the ongoing transformation into a provided block of
+ *	    data so it can be @import 'ed back later on. This is useful in case
+ *	    you want to save partial result of the transformation after
+ *	    processing certain amount of data and reload this partial result
+ *	    multiple times later on for multiple re-use. No data processing
+ *	    happens at this point. Driver must not use req->result.
+ * @import: Import partial state of the transformation. This function loads the
+ *	    entire state of the ongoing transformation from a provided block of
+ *	    data so the transformation can continue from this point onward. No
+ *	    data processing happens at this point. Driver must not use
+ *	    req->result.
+ * @init_tfm: Initialize the cryptographic transformation object.
+ *	      This function is called only once at the instantiation
+ *	      time, right after the transformation context was
+ *	      allocated. In case the cryptographic hardware has
+ *	      some special requirements which need to be handled
+ *	      by software, this function shall check for the precise
+ *	      requirement of the transformation and put any software
+ *	      fallbacks in place.
+ * @exit_tfm: Deinitialize the cryptographic transformation object.

+ * @encrypt: Encrypt a scatterlist of blocks. This function is used to encrypt

+ *	  in place.
+ * @exit: Deinitialize the cryptographic transformation object. This is a
+ *	  counterpart to @init, used to remove various changes set in

+ *
+ * Symmetric key cipher API is used with the ciphers of type
+ * CRYPTO_ALG_TYPE_SKCIPHER (listed as type "skcipher" in /proc/crypto).
+ *
+ * Asynchronous cipher operations imply that the function invocation for a
+ * cipher request returns immediately before the completion of the operation.
+ * The cipher request is scheduled as a separate kernel thread and therefore
+ * load-balanced on the different CPUs via the process scheduler. To allow
+ * the kernel crypto API to inform the caller about the completion of a cipher
+ * request, the caller must provide a callback function. That function is
+ * invoked with the cipher handle when the request completes.
+ *
+ * To support the asynchronous operation, additional information than just the
+ * cipher handle must be supplied to the kernel crypto API. That additional
+ * information is given by filling in the skcipher_request data structure.
+ *
+ * For the symmetric key cipher API, the state is maintained with the tfm
+ * cipher handle. A single tfm can be used across multiple calls and in
+ * parallel. For asynchronous block cipher calls, context data supplied and
+ * only used by the caller can be referenced the request data structure in
+ * addition to the IV used for the cipher request. The maintenance of such
+ * state information would be important for a crypto driver implementer to
+ * have, because when calling the callback function upon completion of the
+ * cipher operation, that callback function may need some information about
+ * which operation just finished if it invoked multiple in parallel. This
+ * state information is unused by the kernel crypto API.

+ * is reference counted to allow waiters to safely wait on an event to complete,
+ * without holding any locks.
+ *
+ * It has 3 different events in total to allow a fine-grained synchronization
+ * between outstanding updates::
+ *
+ *	atomic commit thread			hardware
+ *
+ * 	write new state into hardware	---->	...
+ * 	signal hw_done
+ * 						switch to new state on next
+ * 	...					v/hblank
+ *
+ *	wait for buffers to show up		...
+ *
+ *	...					send completion irq
+ *						irq handler signals flip_done
+ *	cleanup old buffers
+ *
+ * 	signal cleanup_done
+ *
+ * 	wait for flip_done		<----
+ * 	clean up atomic state
+ *
+ * The important bit to know is that &cleanup_done is the terminal event, but the
+ * ordering between &flip_done and &hw_done is entirely up to the specific driver
+ * and modeset state change.
+ *
+ * For an implementation of how to use this look at

+ *
+ * Currently only tracks the state update functions and the opaque driver
+ * private state itself, but in the future might also track which
+ * &drm_modeset_lock is required to duplicate and update this object's state.
+ *
+ * All private objects must be initialized before the DRM device they are
+ * attached to is registered to the DRM subsystem (call to drm_dev_register())
+ * and should stay around until this DRM device is unregistered (call to
+ * drm_dev_unregister()). In other words, private objects lifetime is tied

+ * 1/ all calls to drm_atomic_private_obj_init() must be done before calling

+ *    drm_dev_unregister()
+ *
+ * If that private object is used to store a state shared by multiple
+ * CRTCs, proper care must be taken to ensure that non-blocking commits are
+ * properly ordered to avoid a use-after-free issue.

+ * Indeed, assuming a sequence of two non-blocking &drm_atomic_commit on two

+ * resources shared, there's no guarantee on which commit is going to happen
+ * first. However, the second &drm_atomic_commit will consider the first
+ * &drm_private_obj its old state, and will be in charge of freeing it whenever
+ * the second &drm_atomic_commit is done.
+ *
+ * If the first &drm_atomic_commit happens after it, it will consider its
+ * &drm_private_obj the new state and will be likely to access it, resulting in
+ * an access to a freed memory region. Drivers should store (and get a reference
+ * to) the &drm_crtc_commit structure in our private state in
+ * &drm_mode_config_helper_funcs.atomic_commit_setup, and then wait for that

+	 *    way to achieve that is calling drm_crtc_send_vblank_event()
+	 *    somewhen after drm_crtc_vblank_off() has been called.
+	 *
+	 *  - For a CRTC which is enabled at the end of the commit (even when it
+	 *    undergoes an full modeset) the vblank timestamp and counter must
+	 *    be for the vblank right before the first frame that scans out the
+	 *    new set of buffers. Again the event can only be sent out after the
+	 *    hardware has stopped scanning out the old buffers.
+	 *
+	 *  - Events for disabled CRTCs are not allowed, and drivers can ignore
+	 *    that case.
+	 *
+	 * For very simple hardware without VBLANK interrupt, enabling
+	 * &struct drm_crtc_state.no_vblank makes DRM's atomic commit helpers
+	 * send a fake VBLANK event at the end of the display update after all
+	 * hardware changes have been applied. See
+	 * drm_atomic_helper_fake_vblank().
+	 *
+	 * For more complex hardware this
+	 * can be handled by the drm_crtc_send_vblank_event() function,
+	 * which the driver should call on the provided event upon completion of
+	 * the atomic commit. Note that if the driver supports vblank signalling
+	 * and timestamping the vblank counters and timestamps must agree with
+	 * the ones returned from page flip events. With the current vblank
+	 * helper infrastructure this can be achieved by holding a vblank
+	 * reference while the page flip is pending, acquired through
+	 * drm_crtc_vblank_get() and released with drm_crtc_vblank_put().
+	 * Drivers are free to implement their own vblank counter and timestamp
+	 * tracking though, e.g. if they have accurate timestamp registers in
+	 * hardware.
+	 *
+	 * For hardware which supports some means to synchronize vblank
+	 * interrupt delivery with committing display state there's also
+	 * drm_crtc_arm_vblank_event(). See the documentation of that function
+	 * for a detailed discussion of the constraints it needs to be used
+	 * safely.
+	 *
+	 * If the device can't notify of flip completion in a race-free way
+	 * at all, then the event should be armed just after the page flip is

+	 * vertical blanking, avoiding tearing (except when requested otherwise
+	 * through the DRM_MODE_PAGE_FLIP_ASYNC flag). When an application
+	 * requests a page flip the DRM core verifies that the new frame buffer
+	 * is large enough to be scanned out by the CRTC in the currently
+	 * configured mode and then calls this hook with a pointer to the new
+	 * frame buffer.
+	 *
+	 * The driver must wait for any pending rendering to the new framebuffer
+	 * to complete before executing the flip. It should also wait for any
+	 * pending rendering from other drivers if the underlying buffer is a
+	 * shared dma-buf.
+	 *
+	 * An application can request to be notified when the page flip has
+	 * completed. The drm core will supply a &struct drm_event in the event
+	 * parameter in this case. This can be handled by the
+	 * drm_crtc_send_vblank_event() function, which the driver should call on
+	 * the provided event upon completion of the flip. Note that if
+	 * the driver supports vblank signalling and timestamping the vblank
+	 * counters and timestamps must agree with the ones returned from page
+	 * flip events. With the current vblank helper infrastructure this can
+	 * be achieved by holding a vblank reference while the page flip is
+	 * pending, acquired through drm_crtc_vblank_get() and released with
+	 * drm_crtc_vblank_put(). Drivers are free to implement their own vblank
+	 * counter and timestamp tracking though, e.g. if they have accurate
+	 * timestamp registers in hardware.

+	 *
+	 *  - Checking that the modes, framebuffers, scaling and placement
+	 *    requirements and so on are within the limits of the hardware.
+	 *
+	 *  - Checking that any hidden shared resources are not oversubscribed.
+	 *    This can be shared PLLs, shared lanes, overall memory bandwidth,
+	 *    display fifo space (where shared between planes or maybe even
+	 *    CRTCs).
+	 *
+	 *  - Checking that virtualized resources exported to userspace are not
+	 *    oversubscribed. For various reasons it can make sense to expose
+	 *    more planes, crtcs or encoders than which are physically there. One
+	 *    example is dual-pipe operations (which generally should be hidden
+	 *    from userspace if when lockstepped in hardware, exposed otherwise),
+	 *    where a plane might need 1 hardware plane (if it's just on one
+	 *    pipe), 2 hardware planes (when it spans both pipes) or maybe even
+	 *    shared a hardware plane with a 2nd plane (if there's a compatible
+	 *    plane requested on the area handled by the other pipe).
+	 *
+	 *  - Check that any transitional state is possible and that if
+	 *    requested, the update can indeed be done in the vblank period
+	 *    without temporarily disabling some functions.
+	 *
+	 *  - Check any other constraints the driver or hardware might have.
+	 *
+	 *  - This callback also needs to correctly fill out the &drm_crtc_state
+	 *    in this update to make sure that drm_atomic_crtc_needs_modeset()
+	 *    reflects the nature of the possible update and returns true if and
+	 *    only if the update cannot be applied without tearing within one
+	 *    vblank on that CRTC. The core uses that information to reject
+	 *    updates which require a full modeset (i.e. blanking the screen, or
+	 *    at least pausing updates for a substantial amount of time) if
+	 *    userspace has disallowed that in its request.
+	 *
+	 *  - The driver also does not need to repeat basic input validation
+	 *    like done for the corresponding legacy entry points. The core does
+	 *    that before calling this hook.
+	 *
+	 * See the documentation of @atomic_commit for an exhaustive list of
+	 * error conditions which don't have to be checked at the in this
+	 * callback.
+	 *
+	 * See the documentation for &struct drm_atomic_state for how exactly
+	 * an atomic modeset update is described.

+	 *
+	 * 0 on success or one of the below negative error codes:

+	 *
+	 *  - -EDEADLK, when returned from an attempt to acquire an additional
+	 *    &drm_modeset_lock through drm_modeset_lock().
+	 *
+	 *  - -ENOMEM, if allocating additional state sub-structures failed due
+	 *    to lack of memory.
+	 *
+	 *  - -EINTR, -EAGAIN or -ERESTARTSYS, if the IOCTL should be restarted.
+	 *    This can either be due to a pending signal, or because the driver
+	 *    needs to completely bail out to recover from an exceptional

+	 *    of outstanding updates, but currently no driver supports that.
+	 *    Note that drivers must wait for preceding updates to complete if a
+	 *    synchronous update is requested, they are not allowed to fail the
+	 *    commit in that case.
+	 *
+	 *  - -ENOMEM, if the driver failed to allocate memory. Specifically
+	 *    this can happen when trying to pin framebuffers, which must only
+	 *    be done when committing the state.

+	 *  - -ENOSPC, as a refinement of the more generic -ENOMEM to indicate

+	 *    situation like a GPU hang. From a userspace point of view all errors are
+	 *    treated equally.
+	 *
+	 * This list is exhaustive. Specifically this hook is not allowed to

+ * The .prepare() function is typically called before the display controller
+ * starts to transmit video data. Panel drivers can use this to turn the panel
+ * on and wait for it to become ready. If additional configuration is required
+ * (via a control bus such as I2C, SPI or DSI for example) this is a good time
+ * to do that.
+ *
+ * After the display controller has started transmitting video data, it's safe
+ * to call the .enable() function. This will typically enable the backlight to
+ * make the image on screen visible. Some panels require a certain amount of
+ * time or frames before the image is displayed. This function is responsible
+ * for taking this into account before enabling the backlight to avoid visual
+ * glitches.
+ *
+ * Before stopping video transmission from the display controller it can be
+ * necessary to turn off the panel to avoid visual glitches. This is done in
+ * the .disable() function. Analogously to .enable() this typically involves
+ * turning off the backlight and waiting for some time to make sure no image
+ * is visible on the panel. It is then safe for the display controller to
+ * cease transmission of video data.
+ *
+ * To save power when no video data is transmitted, a driver can power down
+ * the panel. This is the job of the .unprepare() function.
+ *
+ * Backlight can be handled automatically if configured using
+ * drm_panel_of_backlight() or drm_panel_dp_aux_backlight(). Then the driver
+ * does not need to implement the functionality to enable/disable backlight.

+ * of the property with the set of permissible values. This means that when a
+ * driver wants to use a property with the same name on different objects, but
+ * with different value ranges, then it must create property for each one. An
+ * example would be rotation of &drm_plane, when e.g. the primary plane cannot

+ * property structure can be instantiated multiple times for the same object.
+ * Userspace must be able to cope with this and cannot assume that the same
+ * symbolic property will have the same modeset object ID on all modeset
+ * objects.
+ *
+ * Properties are created by one of the special functions, as explained in
+ * detail in the @flags structure member.
+ *
+ * To actually expose a property it must be attached to each object using
+ * drm_object_attach_property(). Currently properties can only be attached to
+ * &drm_connector, &drm_crtc and &drm_plane.
+ *
+ * Properties are also used as the generic metadatatransport for the atomic
+ * IOCTL. Everything that was set directly in structures in the legacy modeset
+ * IOCTLs (like the plane source or destination windows, or e.g. the links to
+ * the CRTC) is exposed as a property with the DRM_MODE_PROP_ATOMIC flag set.

+	 *     Range properties report their minimum and maximum admissible unsigned values.
+	 *     The KMS core verifies that values set by application fit in that
+	 *     range. The range is unsigned. Range properties are created using
+	 *     drm_property_create_range().
+	 *
+	 * DRM_MODE_PROP_SIGNED_RANGE
+	 *     Range properties report their minimum and maximum admissible unsigned values.
+	 *     The KMS core verifies that values set by application fit in that
+	 *     range. The range is signed. Range properties are created using
+	 *     drm_property_create_signed_range().
+	 *
+	 * DRM_MODE_PROP_ENUM
+	 *     Enumerated properties take a numerical value that ranges from 0 to
+	 *     the number of enumerated values defined by the property minus one,
+	 *     and associate a free-formed string name to each value. Applications
+	 *     can retrieve the list of defined value-name pairs and use the
+	 *     numerical value to get and set property instance values. Enum
+	 *     properties are created using drm_property_create_enum().
+	 *
+	 * DRM_MODE_PROP_BITMASK
+	 *     Bitmask properties are enumeration properties that additionally
+	 *     restrict all enumerated values to the 0..63 range. Bitmask property
+	 *     instance values combine one or more of the enumerated bits defined
+	 *     by the property. Bitmask properties are created using
+	 *     drm_property_create_bitmask().
+	 *
+	 * DRM_MODE_PROP_OBJECT
+	 *     Object properties are used to link modeset objects. This is used
+	 *     extensively in the atomic support to create the display pipeline,
+	 *     by linking &drm_framebuffer to &drm_plane, &drm_plane to
+	 *     &drm_crtc and &drm_connector to &drm_crtc. An object property can
+	 *     only link to a specific type of &drm_mode_object, this limit is
+	 *     enforced by the core. Object properties are created using
+	 *     drm_property_create_object().
+	 *
+	 *     Object properties work like blob properties, but in a more
+	 *     general fashion. They are limited to atomic drivers and must have
+	 *     the DRM_MODE_PROP_ATOMIC flag set.
+	 *
+	 * DRM_MODE_PROP_BLOB
+	 *     Blob properties store a binary blob without any format restriction.
+	 *     The binary blobs are created as KMS standalone objects, and blob
+	 *     property instance values store the ID of their associated blob
+	 *     object. Blob properties are created by calling
+	 *     drm_property_create() with DRM_MODE_PROP_BLOB as the type.
+	 *
+	 *     Actual blob objects to contain blob data are created using
+	 *     drm_property_create_blob(), or through the corresponding IOCTL.
+	 *
+	 *     Besides the built-in limit to only accept blob objects blob
+	 *     properties work exactly like object properties. The only reasons
+	 *     blob properties exist is backwards compatibility with existing
+	 *     userspace.
+	 *
+	 * In addition a property can have any combination of the below flags:
+	 *
+	 * DRM_MODE_PROP_ATOMIC
+	 *     Set for properties which encode atomic modeset state. Such
+	 *     properties are not exposed to legacy userspace.
+	 *
+	 * DRM_MODE_PROP_IMMUTABLE
+	 *     Set for properties whose values cannot be changed by
+	 *     userspace. The kernel is allowed to update the value of these
+	 *     properties. This is generally used to expose probe state to
+	 *     userspace, e.g. the EDID, or the connector path property on DP
+	 *     MST sinks. Kernel can update the value of an immutable property
+	 *     by calling drm_object_property_set_value().

+ * The first 224 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
+ * registers. These IDs often match those in the CAR's RST_DEVICES registers,
+ * but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
+ * this case, those clocks are assigned IDs above 224 in order to highlight
+ * this issue. Implementations that interpret these clock IDs as bit values

+ * 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

+ * the gains/offsets are inactive, but volatile and readable.
+ * Thus, the results of the whitebalance algorithm are available to userspace to
+ * read at any time.
+ * AWB == 0: autowhitebalance is off, cluster is in manual mode, user can
+ * configure the gain/offsets directly.
+ * More than that, if the do_white_balance button is
+ * pressed, the driver will perform one-time-adjustment, (preferably with color

+ * 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);

+ *	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 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

+ * This header file describes the Virtual Function (VF) - Physical Function
+ * (PF) communication protocol used by the drivers for all devices starting
+ * from our 40G product line
+ *
+ * Admin queue buffer usage:
+ * desc->opcode is always aqc_opc_send_msg_to_pf
+ * flags, retval, datalen, and data addr are all used normally.
+ * The Firmware copies the cookie fields when sending messages between the
+ * PF and VF, but uses all other fields internally. Due to this limitation,
+ * we must send all messages as "indirect", i.e. using an external buffer.
+ *
+ * All the VSI indexes are relative to the VF. Each VF can have maximum of
+ * three VSIs. All the queue indexes are relative to the VSI.  Each VF can
+ * have a maximum of sixteen queues for all of its VSIs.
+ *
+ * The PF is required to return a status code in v_retval for all messages
+ * except RESET_VF, which does not require any response. The returned value
+ * is of virtchnl_status_code type, defined here.
+ *
+ * In general, VF driver initialization should roughly follow the order of
+ * these opcodes. The VF driver must first validate the API version of the
+ * PF driver, then request a reset, then get resources, then configure
+ * queues and interrupts. After these operations are complete, the VF
+ * driver may start its queues, optionally add MAC and VLAN filters, and
+ * process traffic.

+ *
+ * There are four combinations of endianness and length of the word in linux

+ *
+ * On 64-bit kernels 64-bit LE and BE numbers are naturally ordered in
+ * bitmaps and therefore don't require any special handling.
+ *
+ * On 32-bit kernels 32-bit LE ABI orders lo word of 64-bit number in memory
+ * prior to hi, and 32-bit BE orders hi word prior to lo. The bitmap on the
+ * other hand is represented as an array of 32-bit words and the position of
+ * bit N may therefore be calculated as: word #(N/32) and bit #(N%32) in that
+ * word.  For example, bit #42 is located at 10th position of 2nd word.
+ * It matches 32-bit LE ABI, and we can simply let the compiler store 64-bit
+ * values in memory as it usually does. But for BE we need to swap hi and lo
+ * words manually.
+ *
+ * With all that, the macro BITMAP_FROM_U64() does explicit reordering of hi and
+ * lo parts of u64.  For LE32 it does nothing, and for BE environment it swaps
+ * hi and lo words, as is expected by bitmap.

+ *
+ * At high bit rates, the propagation delay from the TX pin to the RX
+ * pin of the transceiver causes measurement errors: the sample point
+ * on the RX pin might occur on the previous bit.
+ *
+ * To solve this issue, ISO 11898-1 introduces in section 11.3.3
+ * "Transmitter delay compensation" a SSP (Secondary Sample Point)
+ * equal to the distance from the start of the bit time on the TX pin
+ * to the actual measurement on the RX pin.
+ *
+ * This structure contains the parameters to calculate that SSP.
+ *
+ * -+----------- one bit ----------+-- TX pin
+ *  |<--- Sample Point --->|
+ *
+ *                         --+----------- one bit ----------+-- RX pin
+ *  |<-------- TDCV -------->|
+ *                           |<------- TDCO ------->|
+ *  |<----------- Secondary Sample Point ---------->|
+ *
+ * To increase precision, contrary to the other bittiming parameters
+ * which are measured in time quanta, the TDC parameters are measured
+ * in clock periods (also referred as "minimum time quantum" in ISO
+ * 11898-1).
+ *
+ * @tdcv: Transmitter Delay Compensation Value. The time needed for
+ *	the signal to propagate, i.e. the distance, in clock periods,
+ *	from the start of the bit on the TX pin to when it is received
+ *	on the RX pin. @tdcv depends on the controller modes:
+ *
+ *	  CAN_CTRLMODE_TDC_AUTO is set: The transceiver dynamically
+ *	  measures @tdcv for each transmitted CAN FD frame and the
+ *	  value provided here should be ignored.
+ *
+ *	  CAN_CTRLMODE_TDC_MANUAL is set: use the fixed provided @tdcv
+ *	  value.
+ *
+ *	N.B. CAN_CTRLMODE_TDC_AUTO and CAN_CTRLMODE_TDC_MANUAL are
+ *	mutually exclusive. Only one can be set at a time. If both
+ *	CAN_TDC_CTRLMODE_AUTO and CAN_TDC_CTRLMODE_MANUAL are unset,
+ *	TDC is disabled and all the values of this structure should be
+ *	ignored.
+ *
+ * @tdco: Transmitter Delay Compensation Offset. Offset value, in
+ *	clock periods, defining the distance between the start of the
+ *	bit reception on the RX pin of the transceiver and the SSP
+ *	position such that SSP = @tdcv + @tdco.
+ *
+ * @tdcf: Transmitter Delay Compensation Filter window. Defines the
+ *	minimum value for the SSP position in clock periods. If the
+ *	SSP position is less than @tdcf, then no delay compensations
+ *	occur and the normal sampling point is used instead. The
+ *	feature is enabled if and only if @tdcv is set to zero
+ *	(automatic mode) and @tdcf is configured to a value greater

+ * Notes on deprecation:

+ * A *major* release is a release through which all upgrades must pass
+ * (e.g., jewel).  For example, no pre-jewel server will ever talk to
+ * a post-jewel server (mon, osd, etc).
+ *
+ * For feature bits used *only* on the server-side:
+ *
+ *  - In the first phase we indicate that a feature is DEPRECATED as of
+ *    a particular release.  This is the first major release X (say,
+ *    jewel) that does not depend on its peers advertising the feature.
+ *    That is, it safely assumes its peers all have the feature.  We
+ *    indicate this with the DEPRECATED macro.  For example,
+ *
+ *      DEFINE_CEPH_FEATURE_DEPRECATED( 2, 1, MONCLOCKCHECK, JEWEL)
+ *
+ *    because 10.2.z (jewel) did not care if its peers advertised this
+ *    feature bit.
+ *
+ *  - In the second phase we stop advertising the bit and call it
+ *    RETIRED.  This can normally be done in the *next* major release
+ *    following the one in which we marked the feature DEPRECATED.  In
+ *    the above example, for 12.0.z (luminous) we can say:
+ *
+ *      DEFINE_CEPH_FEATURE_RETIRED( 2, 1, MONCLOCKCHECK, JEWEL, LUMINOUS)
+ *
+ *  - The bit can be reused in the first post-luminous release, 13.0.z
+ *    (m).
+ *
+ * This ensures that no two versions who have different meanings for
+ * the bit ever speak to each other.

+/**
+ * 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.

+ * 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):

+ *
+ *   [Buf_Read_Count, Buf_Read_Alloc_Count):

+ *
+ * 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

+ * _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.

+ * If @num_names is non-zero, @board_name should be non-NULL, and @offset

+ * pointing to the matched pointer to a board name within the driver's private
+ * array of static, read-only board type information.
+ *
+ * The @detach handler has two roles.  If a COMEDI device was successfully
+ * configured by the @attach or @auto_attach handler, it is called when the

+ * struct comedi_device - Working data for a COMEDI device
+ * @use_count: Number of open file objects.
+ * @driver: Low-level COMEDI driver attached to this COMEDI device.
+ * @pacer: Optional pointer to a dynamically allocated acquisition pacer
+ *	control.  It is freed automatically after the COMEDI device is
+ *	detached from the low-level driver.
+ * @private: Optional pointer to private data allocated by the low-level
+ *	driver.  It is freed automatically after the COMEDI device is
+ *	detached from the low-level driver.
+ * @class_dev: Sysfs comediX device.
+ * @minor: Minor device number of COMEDI char device (0-47).
+ * @detach_count: Counter incremented every time the COMEDI device is detached.
+ *	Used for checking a previous attachment is still valid.
+ * @hw_dev: Optional pointer to the low-level hardware &struct device.  It is
+ *	required for automatically configured COMEDI devices and optional for
+ *	COMEDI devices configured by the %COMEDI_DEVCONFIG ioctl, although
+ *	the bus-specific COMEDI functions only work if it is set correctly.
+ *	It is also passed to dma_alloc_coherent() for COMEDI subdevices that
+ *	have their 'async_dma_dir' member set to something other than
+ *	%DMA_NONE.
+ * @board_name: Pointer to a COMEDI board name or a COMEDI driver name.  When
+ *	the low-level driver's "attach" handler is called by the handler for
+ *	the %COMEDI_DEVCONFIG ioctl, it either points to a matched board name
+ *	string if the 'num_names' member of the &struct comedi_driver is
+ *	non-zero, otherwise it points to the low-level driver name string.
+ *	When the low-lever driver's "auto_attach" handler is called for an
+ *	automatically configured COMEDI device, it points to the low-level
+ *	driver name string.  The low-level driver is free to change it in its
+ *	"attach" or "auto_attach" handler if it wishes.
+ * @board_ptr: Optional pointer to private, read-only board type information in
+ *	the low-level driver.  If the 'num_names' member of the &struct
+ *	comedi_driver is non-zero, the handler for the %COMEDI_DEVCONFIG ioctl
+ *	will point it to a pointer to a matched board name string within the
+ *	driver's private array of static, read-only board type information when
+ *	calling the driver's "attach" handler.  The low-level driver is free to
+ *	change it.
+ * @attached: Flag indicating that the COMEDI device is attached to a low-level
+ *	driver.
+ * @ioenabled: Flag used to indicate that a PCI device has been enabled and
+ *	its regions requested.
+ * @spinlock: Generic spin-lock for use by the low-level driver.
+ * @mutex: Generic mutex for use by the COMEDI core module.
+ * @attach_lock: &struct rw_semaphore used to guard against the COMEDI device
+ *	being detached while an operation is in progress.  The down_write()
+ *	operation is only allowed while @mutex is held and is used when
+ *	changing @attached and @detach_count and calling the low-level driver's
+ *	"detach" handler.  The down_read() operation is generally used without
+ *	holding @mutex.
+ * @refcount: &struct kref reference counter for freeing COMEDI device.
+ * @n_subdevices: Number of COMEDI subdevices allocated by the low-level
+ *	driver for this device.
+ * @subdevices: Dynamically allocated array of COMEDI subdevices.
+ * @mmio: Optional pointer to a remapped MMIO region set by the low-level
+ *	driver.
+ * @iobase: Optional base of an I/O port region requested by the low-level
+ *	driver.
+ * @iolen: Length of I/O port region requested at @iobase.
+ * @irq: Optional IRQ number requested by the low-level driver.
+ * @read_subdev: Optional pointer to a default COMEDI subdevice operated on by
+ *	the read() file operation.  Set by the low-level driver.
+ * @write_subdev: Optional pointer to a default COMEDI subdevice operated on by
+ *	the write() file operation.  Set by the low-level driver.
+ * @async_queue: Storage for fasync_helper().
+ * @open: Optional pointer to a function set by the low-level driver to be
+ *	called when @use_count changes from 0 to 1.
+ * @close: Optional pointer to a function set by the low-level driver to be
+ *	called when @use_count changed from 1 to 0.
+ * @insn_device_config: Optional pointer to a handler for all sub-instructions
+ *	except %INSN_DEVICE_CONFIG_GET_ROUTES of the %INSN_DEVICE_CONFIG
+ *	instruction.  If this is not initialized by the low-level driver, a
+ *	default handler will be set during post-configuration.
+ * @get_valid_routes: Optional pointer to a handler for the
+ *	%INSN_DEVICE_CONFIG_GET_ROUTES sub-instruction of the
+ *	%INSN_DEVICE_CONFIG instruction set.  If this is not initialized by the
+ *	low-level driver, a default handler that copies zero routes back to the
+ *	user will be used.
+ *
+ * This is the main control data structure for a COMEDI device (as far as the
+ * COMEDI core is concerned).  There are two groups of COMEDI devices -
+ * "legacy" devices that are configured by the handler for the
+ * %COMEDI_DEVCONFIG ioctl, and automatically configured devices resulting
+ * from a call to comedi_auto_config() as a result of a bus driver probe in
+ * a low-level COMEDI driver.  The "legacy" COMEDI devices are allocated
+ * during module initialization if the "comedi_num_legacy_minors" module
+ * parameter is non-zero and use minor device numbers from 0 to
+ * comedi_num_legacy_minors minus one.  The automatically configured COMEDI
+ * devices are allocated on demand and use minor device numbers from
+ * comedi_num_legacy_minors to 47.

+ *
+ * The state space has three sections: PREPARE, STARTING and ONLINE.
+ *
+ * PREPARE: The callbacks are invoked on a control CPU before the

+ *
+ * STARTING: The callbacks are invoked on the hotplugged CPU from the low level

+ * ONLINE: The callbacks are invoked on the hotplugged CPU from the per CPU
+ * hotplug thread with interrupts and preemption enabled.
+ *
+ * Adding explicit states to this enum is only necessary when:
+ *
+ * 1) The state is within the STARTING section
+ *
+ * 2) The state has ordering constraints vs. other states in the

+ *
+ * If neither #1 nor #2 apply, please use the dynamic state space when

+ *	        program a supplied key into the hardware or store the key in the
+ *	        transformation context for programming it later. Note that this
+ *	        function does modify the transformation context. This function
+ *	        can be called multiple times during the existence of the
+ *	        transformation object, so one must make sure the key is properly
+ *	        reprogrammed into the hardware. This function is also
+ *	        responsible for checking the key length for validity.
+ * @cia_encrypt: Encrypt a single block. This function is used to encrypt a
+ *		 single block of data, which must be @cra_blocksize big. This
+ *		 always operates on a full @cra_blocksize and it is not possible
+ *		 to encrypt a block of smaller size. The supplied buffers must
+ *		 therefore also be at least of @cra_blocksize size. Both the
+ *		 input and output buffers are always aligned to @cra_alignmask.
+ *		 In case either of the input or output buffer supplied by user
+ *		 of the crypto API is not aligned to @cra_alignmask, the crypto
+ *		 API will re-align the buffers. The re-alignment means that a
+ *		 new buffer will be allocated, the data will be copied into the
+ *		 new buffer, then the processing will happen on the new buffer,
+ *		 then the data will be copied back into the original buffer and
+ *		 finally the new buffer will be freed. In case a software
+ *		 fallback was put in place in the @cra_init call, this function
+ *		 might need to use the fallback if the algorithm doesn't support
+ *		 all of the key sizes. In case the key was stored in
+ *		 transformation context, the key might need to be re-programmed
+ *		 into the hardware in this function. This function shall not
+ *		 modify the transformation context, as this function may be
+ *		 called in parallel with the same transformation object.
+ * @cia_decrypt: Decrypt a single block. This is a reverse counterpart to
+ *		 @cia_encrypt, and the conditions are exactly the same.
+ *
+ * All fields are mandatory and must be filled.

+/**
+ * struct crypto_alg - definition of a cryptograpic cipher algorithm
+ * @cra_flags: Flags describing this transformation. See include/linux/crypto.h
+ *	       CRYPTO_ALG_* flags for the flags which go in here. Those are
+ *	       used for fine-tuning the description of the transformation
+ *	       algorithm.
+ * @cra_blocksize: Minimum block size of this transformation. The size in bytes
+ *		   of the smallest possible unit which can be transformed with
+ *		   this algorithm. The users must respect this value.
+ *		   In case of HASH transformation, it is possible for a smaller
+ *		   block than @cra_blocksize to be passed to the crypto API for
+ *		   transformation, in case of any other transformation type, an
+ * 		   error will be returned upon any attempt to transform smaller
+ *		   than @cra_blocksize chunks.
+ * @cra_ctxsize: Size of the operational context of the transformation. This
+ *		 value informs the kernel crypto API about the memory size
+ *		 needed to be allocated for the transformation context.
+ * @cra_alignmask: Alignment mask for the input and output data buffer. The data
+ *		   buffer containing the input data for the algorithm must be
+ *		   aligned to this alignment mask. The data buffer for the
+ *		   output data must be aligned to this alignment mask. Note that
+ *		   the Crypto API will do the re-alignment in software, but
+ *		   only under special conditions and there is a performance hit.
+ *		   The re-alignment happens at these occasions for different
+ *		   @cra_u types: cipher -- For both input data and output data
+ *		   buffer; ahash -- For output hash destination buf; shash --
+ *		   For output hash destination buf.
+ *		   This is needed on hardware which is flawed by design and
+ *		   cannot pick data from arbitrary addresses.
+ * @cra_priority: Priority of this transformation implementation. In case
+ *		  multiple transformations with same @cra_name are available to
+ *		  the Crypto API, the kernel will use the one with highest
+ *		  @cra_priority.
+ * @cra_name: Generic name (usable by multiple implementations) of the
+ *	      transformation algorithm. This is the name of the transformation
+ *	      itself. This field is used by the kernel when looking up the
+ *	      providers of particular transformation.
+ * @cra_driver_name: Unique name of the transformation provider. This is the
+ *		     name of the provider of the transformation. This can be any
+ *		     arbitrary value, but in the usual case, this contains the
+ *		     name of the chip or provider and the name of the
+ *		     transformation algorithm.
+ * @cra_type: Type of the cryptographic transformation. This is a pointer to
+ *	      struct crypto_type, which implements callbacks common for all
+ *	      transformation types. There are multiple options, such as
+ *	      &crypto_skcipher_type, &crypto_ahash_type, &crypto_rng_type.
+ *	      This field might be empty. In that case, there are no common
+ *	      callbacks. This is the case for: cipher, compress, shash.
+ * @cra_u: Callbacks implementing the transformation. This is a union of
+ *	   multiple structures. Depending on the type of transformation selected
+ *	   by @cra_type and @cra_flags above, the associated structure must be
+ *	   filled with callbacks. This field might be empty. This is the case
+ *	   for ahash, shash.
+ * @cra_init: Initialize the cryptographic transformation object. This function
+ *	      is used to initialize the cryptographic transformation object.
+ *	      This function is called only once at the instantiation time, right
+ *	      after the transformation context was allocated. In case the
+ *	      cryptographic hardware has some special requirements which need to
+ *	      be handled by software, this function shall check for the precise
+ *	      requirement of the transformation and put any software fallbacks
+ *	      in place.
+ * @cra_exit: Deinitialize the cryptographic transformation object. This is a
+ *	      counterpart to @cra_init, used to remove various changes set in
+ *	      @cra_init.
+ * @cra_u.cipher: Union member which contains a single-block symmetric cipher
+ *		  definition. See @struct @cipher_alg.
+ * @cra_u.compress: Union member which contains a (de)compression algorithm.
+ *		    See @struct @compress_alg.
+ * @cra_module: Owner of this transformation implementation. Set to THIS_MODULE
+ * @cra_list: internally used
+ * @cra_users: internally used
+ * @cra_refcnt: internally used
+ * @cra_destroy: internally used
+ *
+ * The struct crypto_alg describes a generic Crypto API algorithm and is common
+ * for all of the transformations. Any variable not documented here shall not
+ * be used by a cipher implementation as it is internal to the Crypto API.

- *		few other things that generate uevents to add the environment
- *		variables.
- * @devnode:	Callback to provide the devtmpfs.
- * @class_release: Called to release this class.
- * @dev_release: Called to release the device.
- * @suspend:	Used to put the device to sleep mode, usually to a low power

- * @resume:	Used to bring the device from the sleep mode.
- * @ns_type:	Callbacks so sysfs can detemine namespaces.

+ * struct bus_type - The bus type of the device
+ *
+ * @name:	The name of the bus.
+ * @dev_name:	Used for subsystems to enumerate devices like ("foo%u", dev->id).
+ * @bus_groups:	Default attributes of the bus.
+ * @dev_groups:	Default attributes of the devices on the bus.
+ * @drv_groups: Default attributes of the device drivers on the bus.
+ * @match:	Called, perhaps multiple times, whenever a new device or driver
+ *		is added for this bus. It should return a positive value if the
+ *		given device can be handled by the given driver and zero
+ *		otherwise. It may also return error code if determining that
+ *		the driver supports the device is not possible. In case of
+ *		-EPROBE_DEFER it will queue the device for deferred probing.
+ * @uevent:	Called when a device is added, removed, or a few other things
+ *		that generate uevents to add the environment variables.
+ * @probe:	Called when a new device or driver add to this bus, and callback
+ *		the specific driver's probe to initial the matched device.
+ * @sync_state:	Called to sync device state to software state after all the
+ *		state tracking consumers linked to this device (present at
+ *		the time of late_initcall) have successfully bound to a
+ *		driver. If the device has no consumers, this function will
+ *		be called at late_initcall_sync level. If the device has
+ *		consumers that are never bound to a driver, this function
+ *		will never get called until they do.
+ * @remove:	Called when a device removed from this bus.
+ * @shutdown:	Called at shut-down time to quiesce the device.
+ *
+ * @online:	Called to put the device back online (after offlining it).
+ * @offline:	Called to put the device offline for hot-removal. May fail.
+ *
+ * @suspend:	Called when a device on this bus wants to go to sleep mode.
+ * @resume:	Called to bring a device on this bus out of sleep mode.
+ * @num_vf:	Called to find out how many virtual functions a device on this
+ *		bus supports.
+ * @dma_configure:	Called to setup DMA configuration on a device on
+ *			this bus.
+ * @dma_cleanup:	Called to cleanup DMA configuration on a device on
+ *			this bus.
+ * @pm:		Power management operations of this bus, callback the specific
+ *		device driver's pm-ops.
+ * @iommu_ops:  IOMMU specific operations for this bus, used to attach IOMMU
+ *              driver implementations to a bus and allow the driver to do
+ *              bus-specific setup
+ * @need_parent_lock:	When probing or removing a device on this bus, the
+ *			device core should lock the device's parent.
+ *
+ * A bus is a channel between the processor and one or more devices. For the
+ * purposes of the device model, all devices are connected via a bus, even if
+ * it is an internal, virtual, "platform" bus. Buses can plug into each other.
+ * A USB controller is usually a PCI device, for example. The device model
+ * represents the actual connections between buses and the devices they control.
+ * A bus is represented by the bus_type structure. It contains the name, the
+ * default attributes, the bus' methods, PM operations, and the driver core's
+ * private data.

+ * @mod_name:	Used for built-in modules.
+ * @suppress_bind_attrs: Disables bind/unbind via sysfs.
+ * @probe_type:	Type of the probe (synchronous or asynchronous) to use.
+ * @of_match_table: The open firmware table.
+ * @acpi_match_table: The ACPI match table.
+ * @probe:	Called to query the existence of a specific device,
+ *		whether this driver can work with it, and bind the driver
+ *		to a specific device.
+ * @sync_state:	Called to sync device state to software state after all the
+ *		state tracking consumers linked to this device (present at
+ *		the time of late_initcall) have successfully bound to a
+ *		driver. If the device has no consumers, this function will
+ *		be called at late_initcall_sync level. If the device has
+ *		consumers that are never bound to a driver, this function
+ *		will never get called until they do.
+ * @remove:	Called when the device is removed from the system to
+ *		unbind a device from this driver.
+ * @shutdown:	Called at shut-down time to quiesce the device.
+ * @suspend:	Called to put the device to sleep mode. Usually to a
+ *		low power state.
+ * @resume:	Called to bring a device from sleep mode.
+ * @groups:	Default attributes that get created by the driver core
+ *		automatically.
+ * @dev_groups:	Additional attributes attached to device instance once
+ *		it is bound to the driver.
+ * @pm:		Power management operations of the device which matched
+ *		this driver.
+ * @coredump:	Called when sysfs entry is written to. The device driver
+ *		is expected to call the dev_coredump API resulting in a
+ *		uevent.
+ * @p:		Driver core's private data, no one other than the driver
+ *		core can touch this.
+ *
+ * The device driver-model tracks all of the drivers known to the system.
+ * The main reason for this tracking is to enable the driver core to match
+ * up drivers with new devices. Once drivers are known objects within the
+ * system, however, a number of other things become possible. Device drivers
+ * can export information and configuration variables that are independent

+	 * the time this function returns.  Drivers which pipeline their buffer
+	 * moves internally must wait for all moves and clears to complete.
+	 * Dynamic exporters do not need to follow this rule: For non-dynamic

+	 * - Drivers must add a read fence through dma_resv_add_fence() with the
+	 *   DMA_RESV_USAGE_READ flag for anything the userspace API considers a
+	 *   read access. This highly depends upon the API and window system.
+	 *
+	 * - Similarly drivers must add a write fence through
+	 *   dma_resv_add_fence() with the DMA_RESV_USAGE_WRITE flag for
+	 *   anything the userspace API considers write access.
+	 *
+	 * - Drivers may just always add a write fence, since that only
+	 *   causes unnecessary synchronization, but no correctness issues.
+	 *
+	 * - Some drivers only expose a synchronous userspace API with no
+	 *   pipelining across drivers. These do not set any fences for their
+	 *   access. An example here is v4l.
+	 *
+	 * - Driver should use dma_resv_usage_rw() when retrieving fences as
+	 *   dependency for implicit synchronization.
+	 *
+	 * DYNAMIC IMPORTER RULES:
+	 *
+	 * Dynamic importers, see dma_buf_attachment_is_dynamic(), have
+	 * additional constraints on how they set up fences:
+	 *
+	 * - Dynamic importers must obey the write fences and wait for them to
+	 *   signal before allowing access to the buffer's underlying storage
+	 *   through the device.
+	 *
+	 * - Dynamic importers should set fences for any access that they can't
+	 *   disable immediately from their &dma_buf_attach_ops.move_notify
+	 *   callback.
+	 *
+	 * IMPORTANT:

- * Contiguous Memory Allocator
- *
- *   The Contiguous Memory Allocator (CMA) makes it possible to
- *   allocate big contiguous chunks of memory after the system has
- *   booted.
- *
- * Why is it needed?
- *
- *   Various devices on embedded systems have no scatter-getter and/or
- *   IO map support and require contiguous blocks of memory to
- *   operate.  They include devices such as cameras, hardware video
- *   coders, etc.
- *
- *   Such devices often require big memory buffers (a full HD frame
- *   is, for instance, more then 2 mega pixels large, i.e. more than 6
- *   MB of memory), which makes mechanisms such as kmalloc() or
- *   alloc_page() ineffective.
- *
- *   At the same time, a solution where a big memory region is
- *   reserved for a device is suboptimal since often more memory is
- *   reserved then strictly required and, moreover, the memory is
- *   inaccessible to page system even if device drivers don't use it.
- *
- *   CMA tries to solve this issue by operating on memory regions
- *   where only movable pages can be allocated from.  This way, kernel
- *   can use the memory for pagecache and when device driver requests
- *   it, allocated pages can be migrated.
- *
- * Driver usage
- *
- *   CMA should not be used by the device drivers directly. It is
- *   only a helper framework for dma-mapping subsystem.
- *
- *   For more information, see kernel-docs in drivers/base/dma-contiguous.c

-/*
- * Concepts used at the EDAC subsystem
- *
- * There are several things to be aware of that aren't at all obvious:
- *
- * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
- *
- * These are some of the many terms that are thrown about that don't always
- * mean what people think they mean (Inconceivable!).  In the interest of
- * creating a common ground for discussion, terms and their definitions
- * will be established.
- *
- * Memory devices:	The individual DRAM chips on a memory stick.  These
- *			devices commonly output 4 and 8 bits each (x4, x8).
- *			Grouping several of these in parallel provides the
- *			number of bits that the memory controller expects:
- *			typically 72 bits, in order to provide 64 bits +
- *			8 bits of ECC data.
- *
- * Memory Stick:	A printed circuit board that aggregates multiple
- *			memory devices in parallel.  In general, this is the
- *			Field Replaceable Unit (FRU) which gets replaced, in
- *			the case of excessive errors. Most often it is also
- *			called DIMM (Dual Inline Memory Module).
- *
- * Memory Socket:	A physical connector on the motherboard that accepts
- *			a single memory stick. Also called as "slot" on several
- *			datasheets.
- *
- * Channel:		A memory controller channel, responsible to communicate
- *			with a group of DIMMs. Each channel has its own
- *			independent control (command) and data bus, and can
- *			be used independently or grouped with other channels.
- *
- * Branch:		It is typically the highest hierarchy on a
- *			Fully-Buffered DIMM memory controller.
- *			Typically, it contains two channels.
- *			Two channels at the same branch can be used in single
- *			mode or in lockstep mode.
- *			When lockstep is enabled, the cacheline is doubled,
- *			but it generally brings some performance penalty.
- *			Also, it is generally not possible to point to just one
- *			memory stick when an error occurs, as the error
- *			correction code is calculated using two DIMMs instead
- *			of one. Due to that, it is capable of correcting more
- *			errors than on single mode.
- *
- * Single-channel:	The data accessed by the memory controller is contained
- *			into one dimm only. E. g. if the data is 64 bits-wide,
- *			the data flows to the CPU using one 64 bits parallel
- *			access.
- *			Typically used with SDR, DDR, DDR2 and DDR3 memories.
- *			FB-DIMM and RAMBUS use a different concept for channel,
- *			so this concept doesn't apply there.
- *
- * Double-channel:	The data size accessed by the memory controller is
- *			interlaced into two dimms, accessed at the same time.
- *			E. g. if the DIMM is 64 bits-wide (72 bits with ECC),
- *			the data flows to the CPU using a 128 bits parallel
- *			access.
- *
- * Chip-select row:	This is the name of the DRAM signal used to select the
- *			DRAM ranks to be accessed. Common chip-select rows for
- *			single channel are 64 bits, for dual channel 128 bits.
- *			It may not be visible by the memory controller, as some
- *			DIMM types have a memory buffer that can hide direct
- *			access to it from the Memory Controller.
- *
- * Single-Ranked stick:	A Single-ranked stick has 1 chip-select row of memory.
- *			Motherboards commonly drive two chip-select pins to
- *			a memory stick. A single-ranked stick, will occupy
- *			only one of those rows. The other will be unused.
- *
- * Double-Ranked stick:	A double-ranked stick has two chip-select rows which
- *			access different sets of memory devices.  The two
- *			rows cannot be accessed concurrently.
- *
- * Double-sided stick:	DEPRECATED TERM, see Double-Ranked stick.
- *			A double-sided stick has two chip-select rows which
- *			access different sets of memory devices. The two
- *			rows cannot be accessed concurrently. "Double-sided"
- *			is irrespective of the memory devices being mounted
- *			on both sides of the memory stick.
- *
- * Socket set:		All of the memory sticks that are required for
- *			a single memory access or all of the memory sticks
- *			spanned by a chip-select row.  A single socket set
- *			has two chip-select rows and if double-sided sticks
- *			are used these will occupy those chip-select rows.
- *
- * Bank:		This term is avoided because it is unclear when
- *			needing to distinguish between chip-select rows and
- *			socket sets.
- *
- * Controller pages:
- *
- * Physical pages:
- *
- * Virtual pages:
- *
- *
- * STRUCTURE ORGANIZATION AND CHOICES

- *
- * PS - I enjoyed writing all that about as much as you enjoyed reading it.

- * The below are the various read and write types that we support. Some of

- * block layer and IO scheduler. Terminology:
- *
- *	The block layer uses device plugging to defer IO a little bit, in
- *	the hope that we will see more IO very shortly. This increases
- *	coalescing of adjacent IO and thus reduces the number of IOs we
- *	have to send to the device. It also allows for better queuing,
- *	if the IO isn't mergeable. If the caller is going to be waiting
- *	for the IO, then he must ensure that the device is unplugged so
- *	that the IO is dispatched to the driver.
- *
- *	All IO is handled async in Linux. This is fine for background
- *	writes, but for reads or writes that someone waits for completion
- *	on, we want to notify the block layer and IO scheduler so that they
- *	know about it. That allows them to make better scheduling
- *	decisions. So when the below references 'sync' and 'async', it
- *	is referencing this priority hint.
- *
- * With that in mind, the available types are:
- *
- * READ			A normal read operation. Device will be plugged.
- * READ_SYNC		A synchronous read. Device is not plugged, caller can
- *			immediately wait on this read without caring about
- *			unplugging.
- * READA		Used for read-ahead operations. Lower priority, and the
- *			block layer could (in theory) choose to ignore this
- *			request if it runs into resource problems.
- * WRITE		A normal async write. Device will be plugged.
- * WRITE_SYNC		Synchronous write. Identical to WRITE, but passes down
- *			the hint that someone will be waiting on this IO
- *			shortly. The write equivalent of READ_SYNC.
- * WRITE_ODIRECT	Special case write for O_DIRECT only.
- * WRITE_FLUSH		Like WRITE_SYNC but with preceding cache flush.
- * WRITE_FUA		Like WRITE_SYNC but data is guaranteed to be on
- *			non-volatile media on completion.
- * WRITE_FLUSH_FUA	Combination of WRITE_FLUSH and FUA. The IO is preceded
- *			by a cache flush and data is guaranteed to be on
- *			non-volatile media on completion.

+ * Generic device object for MC object devices that are "attached" to a
+ * MC bus.
+ *
+ * NOTES:
+ * - For a non-DPRC object its icid is the same as its parent DPRC's icid.
+ * - The SMMU notifier callback gets invoked after device_add() has been
+ *   called for an MC object device, but before the device-specific probe
+ *   callback gets called.
+ * - DP_OBJ_DPRC objects are the only MC objects that have built-in MC
+ *   portals. For all other MC objects, their device drivers are responsible for
+ *   allocating MC portals for them by calling fsl_mc_portal_allocate().
+ * - Some types of MC objects (e.g., DP_OBJ_DPBP, DP_OBJ_DPCON) are
+ *   treated as resources that can be allocated/deallocated from the
+ *   corresponding resource pool in the object's parent DPRC, using the
+ *   fsl_mc_object_allocate()/fsl_mc_object_free() functions. These MC objects
+ *   are known as "allocatable" objects. For them, the corresponding
+ *   fsl_mc_device's 'resource' points to the associated resource object.
+ *   For MC objects that are not allocatable (e.g., DP_OBJ_DPRC, DP_OBJ_DPNI),
+ *   'resource' is NULL.

+/**
+ * DOC: Generic radix trees/sparse arrays
+ *
+ * Very simple and minimalistic, supporting arbitrary size entries up to
+ * PAGE_SIZE.
+ *
+ * A genradix is defined with the type it will store, like so:
+ *
+ * static GENRADIX(struct foo) foo_genradix;
+ *
+ * The main operations are:
+ *
+ * - genradix_init(radix) - initialize an empty genradix
+ *
+ * - genradix_free(radix) - free all memory owned by the genradix and
+ *   reinitialize it
+ *
+ * - genradix_ptr(radix, idx) - gets a pointer to the entry at idx, returning
+ *   NULL if that entry does not exist
+ *
+ * - genradix_ptr_alloc(radix, idx, gfp) - gets a pointer to an entry,
+ *   allocating it if necessary
+ *
+ * - genradix_for_each(radix, iter, p) - iterate over each entry in a genradix
+ *
+ * The radix tree allocates one page of entries at a time, so entries may exist
+ * that were never explicitly allocated - they will be initialized to all
+ * zeroes.
+ *
+ * Internally, a genradix is just a radix tree of pages, and indexing works in
+ * terms of byte offsets. The wrappers in this header file use sizeof on the
+ * type the radix contains to calculate a byte offset from the index - see
+ * __idx_to_offset.

+ * 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
+ * loop around allocator.
+ * Using this flag for costly allocations is _highly_ discouraged.

+ * DOC: Useful GFP flag combinations
+ *
+ * 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. 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.

+ * struct gpio_chip - abstract a GPIO controller
+ * @label: a functional name for the GPIO device, such as a part
+ *	number or the name of the SoC IP-block implementing it.
+ * @gpiodev: the internal state holder, opaque struct
+ * @parent: optional parent device providing the GPIOs
+ * @fwnode: optional fwnode providing this controller's properties
+ * @owner: helps prevent removal of modules exporting active GPIOs
+ * @request: optional hook for chip-specific activation, such as
+ *	enabling module power and clock; may sleep
+ * @free: optional hook for chip-specific deactivation, such as
+ *	disabling module power and clock; may sleep
+ * @get_direction: returns direction for signal "offset", 0=out, 1=in,
+ *	(same as GPIO_LINE_DIRECTION_OUT / GPIO_LINE_DIRECTION_IN),
+ *	or negative error. It is recommended to always implement this
+ *	function, even on input-only or output-only gpio chips.
+ * @direction_input: configures signal "offset" as input, or returns error
+ *	This can be omitted on input-only or output-only gpio chips.
+ * @direction_output: configures signal "offset" as output, or returns error
+ *	This can be omitted on input-only or output-only gpio chips.
+ * @get: returns value for signal "offset", 0=low, 1=high, or negative error
+ * @get_multiple: reads values for multiple signals defined by "mask" and
+ *	stores them in "bits", returns 0 on success or negative error
+ * @set: assigns output value for signal "offset"
+ * @set_multiple: assigns output values for multiple signals defined by "mask"
+ * @set_config: optional hook for all kinds of settings. Uses the same
+ *	packed config format as generic pinconf.
+ * @to_irq: optional hook supporting non-static gpiod_to_irq() mappings;
+ *	implementation may not sleep
+ * @dbg_show: optional routine to show contents in debugfs; default code
+ *	will be used when this is omitted, but custom code can show extra
+ *	state (such as pullup/pulldown configuration).
+ * @init_valid_mask: optional routine to initialize @valid_mask, to be used if
+ *	not all GPIOs are valid.
+ * @add_pin_ranges: optional routine to initialize pin ranges, to be used when
+ *	requires special mapping of the pins that provides GPIO functionality.
+ *	It is called after adding GPIO chip and before adding IRQ chip.
+ * @en_hw_timestamp: Dependent on GPIO chip, an optional routine to
+ *	enable hardware timestamp.
+ * @dis_hw_timestamp: Dependent on GPIO chip, an optional routine to
+ *	disable hardware timestamp.
+ * @base: identifies the first GPIO number handled by this chip;
+ *	or, if negative during registration, requests dynamic ID allocation.
+ *	DEPRECATION: providing anything non-negative and nailing the base
+ *	offset of GPIO chips is deprecated. Please pass -1 as base to
+ *	let gpiolib select the chip base in all possible cases. We want to
+ *	get rid of the static GPIO number space in the long run.
+ * @ngpio: the number of GPIOs handled by this controller; the last GPIO
+ *	handled is (base + ngpio - 1).
+ * @offset: when multiple gpio chips belong to the same device this
+ *	can be used as offset within the device so friendly names can
+ *	be properly assigned.
+ * @names: if set, must be an array of strings to use as alternative
+ *      names for the GPIOs in this chip. Any entry in the array
+ *      may be NULL if there is no alias for the GPIO, however the
+ *      array must be @ngpio entries long.  A name can include a single printk
+ *      format specifier for an unsigned int.  It is substituted by the actual
+ *      number of the gpio.
+ * @can_sleep: flag must be set iff get()/set() methods sleep, as they
+ *	must while accessing GPIO expander chips over I2C or SPI. This
+ *	implies that if the chip supports IRQs, these IRQs need to be threaded
+ *	as the chip access may sleep when e.g. reading out the IRQ status
+ *	registers.
+ * @read_reg: reader function for generic GPIO
+ * @write_reg: writer function for generic GPIO
+ * @be_bits: if the generic GPIO has big endian bit order (bit 31 is representing
+ *	line 0, bit 30 is line 1 ... bit 0 is line 31) this is set to true by the
+ *	generic GPIO core. It is for internal housekeeping only.
+ * @reg_dat: data (in) register for generic GPIO
+ * @reg_set: output set register (out=high) for generic GPIO
+ * @reg_clr: output clear register (out=low) for generic GPIO
+ * @reg_dir_out: direction out setting register for generic GPIO
+ * @reg_dir_in: direction in setting register for generic GPIO
+ * @bgpio_dir_unreadable: indicates that the direction register(s) cannot
+ *	be read and we need to rely on out internal state tracking.
+ * @bgpio_bits: number of register bits used for a generic GPIO i.e.
+ *	<register width> * 8
+ * @bgpio_lock: used to lock chip->bgpio_data. Also, this is needed to keep
+ *	shadowed and real data registers writes together.
+ * @bgpio_data:	shadowed data register for generic GPIO to clear/set bits
+ *	safely.
+ * @bgpio_dir: shadowed direction register for generic GPIO to clear/set
+ *	direction safely. A "1" in this word means the line is set as
+ *	output.
+ *
+ * A gpio_chip can help platforms abstract various sources of GPIOs so
+ * they can all be accessed through a common programming interface.
+ * Example sources would be SOC controllers, FPGAs, multifunction
+ * chips, dedicated GPIO expanders, and so on.
+ *
+ * Each chip controls a number of signals, identified in method calls
+ * by "offset" values in the range 0..(@ngpio - 1).  When those signals
+ * are referenced through calls like gpio_get_value(gpio), the offset
+ * is calculated by subtracting @base from the gpio number.

+ *			given, the name of the device is used
+ * @fwnode:		(Optional) The firmware node.
+ *			If not given, the fwnode of the parent is used.
+ * @label:		(Optional) Descriptive name for GPIO controller.
+ *			If not given, the name of the device is used.
+ * @ngpio:		Number of GPIOs
+ * @names:		(Optional) Array of names for gpios
+ * @reg_dat_base:	(Optional) (in) register base address
+ * @reg_set_base:	(Optional) set register base address
+ * @reg_clr_base:	(Optional) clear register base address
+ * @reg_dir_in_base:	(Optional) in setting register base address
+ * @reg_dir_out_base:	(Optional) out setting register base address
+ * @reg_stride:		(Optional) May be set if the registers (of the
+ *			same type, dat, set, etc) are not consecutive.
+ * @ngpio_per_reg:	Number of GPIOs per register
+ * @irq_domain:		(Optional) IRQ domain if the controller is
+ *			interrupt-capable
+ * @reg_mask_xlate:     (Optional) Translates base address and GPIO
+ *			offset to a register/bitmask pair. If not
+ *			given the default gpio_regmap_simple_xlate()
+ *			is used.
+ * @drvdata:		(Optional) Pointer to driver specific data which is
+ *			not used by gpio-remap but is provided "as is" to the
+ *			driver callback(s).
+ *
+ * The ->reg_mask_xlate translates a given base address and GPIO offset to
+ * register and mask pair. The base address is one of the given register
+ * base addresses in this structure.
+ *
+ * Although all register base addresses are marked as optional, there are
+ * several rules:
+ *     1. if you only have @reg_dat_base set, then it is input-only
+ *     2. if you only have @reg_set_base set, then it is output-only
+ *     3. if you have either @reg_dir_in_base or @reg_dir_out_base set, then
+ *        you have to set both @reg_dat_base and @reg_set_base
+ *     4. if you have @reg_set_base set, you may also set @reg_clr_base to have
+ *        two different registers for setting and clearing the output. This is
+ *        also valid for the output-only case.
+ *     5. @reg_dir_in_base and @reg_dir_out_base are exclusive; is there really
+ *        hardware which has redundant registers?
+ *
+ * Note: All base addresses may have the special value %GPIO_REGMAP_ADDR_ZERO
+ * which forces the address to the value 0.

+ * Returns: The virtual address of the mapping
+ *
+ * In fact a wrapper around kmap_local_page() which also disables pagefaults
+ * and, depending on PREEMPT_RT configuration, also CPU migration and
+ * preemption. Therefore users should not count on the latter two side effects.
+ *
+ * Mappings should always be released by kunmap_atomic().
+ *
+ * Do not use in new code. Use kmap_local_page() instead.
+ *
+ * It is used in atomic context when code wants to access the contents of a
+ * page that might be allocated from high memory (see __GFP_HIGHMEM), for
+ * example a page in the pagecache.  The API has two functions, and they
+ * can be used in a manner similar to the following::
+ *
+ *   // Find the page of interest.
+ *   struct page *page = find_get_page(mapping, offset);
+ *
+ *   // Gain access to the contents of that page.
+ *   void *vaddr = kmap_atomic(page);
+ *
+ *   // Do something to the contents of that page.
+ *   memset(vaddr, 0, PAGE_SIZE);
+ *
+ *   // Unmap that page.
+ *   kunmap_atomic(vaddr);
+ *
+ * Note that the kunmap_atomic() call takes the result of the kmap_atomic()
+ * call, not the argument.
+ *
+ * If you need to map two pages because you want to copy from one page to
+ * another you need to keep the kmap_atomic calls strictly nested, like:
+ *
+ * vaddr1 = kmap_atomic(page1);
+ * vaddr2 = kmap_atomic(page2);
+ *
+ * memcpy(vaddr1, vaddr2, PAGE_SIZE);
+ *
+ * kunmap_atomic(vaddr2);
+ * kunmap_atomic(vaddr1);

+ *
+ * Since this function will walk all the pgtable pages (including not only
+ * high-level pgtable page, but also PUD entry that can be unshared
+ * concurrently for VM_SHARED), the caller of this function should be
+ * responsible of its thread safety.  One can follow this rule:
+ *
+ *  (1) For private mappings: pmd unsharing is not possible, so holding the
+ *      mmap_lock for either read or write is sufficient. Most callers
+ *      already hold the mmap_lock, so normally, no special action is
+ *      required.
+ *
+ *  (2) For shared mappings: pmd unsharing is possible (so the PUD-ranged
+ *      pgtable page can go away from under us!  It can be done by a pmd
+ *      unshare with a follow up munmap() on the other process), then we
+ *      need either:
+ *
+ *     (2.1) hugetlb vma lock read or write held, to make sure pmd unshare
+ *           won't happen upon the range (it also makes sure the pte_t we
+ *           read is the right and stable one), or,
+ *
+ *     (2.2) hugetlb mapping i_mmap_rwsem lock held read or write, to make
+ *           sure even if unshare happened the racy unmap() will wait until
+ *           i_mmap_rwsem is released.
+ *
+ * Option (2.1) is the safest, which guarantees pte stability from pmd
+ * sharing pov, until the vma lock released.  Option (2.2) doesn't protect
+ * a concurrent pmd unshare, but it makes sure the pgtable page is safe to
+ * access.

- * In Linux, we implement the KVP functionality in two components:
- * 1) The kernel component which is packaged as part of the hv_utils driver
- * is responsible for communicating with the host and responsible for
- * implementing the host/guest protocol. 2) A user level daemon that is
- * responsible for data gathering.
- *
- * Host/Guest Protocol: The host iterates over an index and expects the guest
- * to assign a key name to the index and also return the value corresponding to
- * the key. The host will have atmost one KVP transaction outstanding at any
- * given point in time. The host side iteration stops when the guest returns
- * an error. Microsoft has specified the following mapping of key names to
- * host specified index:
- *
- *	Index		Key Name
- *	0		FullyQualifiedDomainName
- *	1		IntegrationServicesVersion
- *	2		NetworkAddressIPv4
- *	3		NetworkAddressIPv6
- *	4		OSBuildNumber
- *	5		OSName
- *	6		OSMajorVersion
- *	7		OSMinorVersion
- *	8		OSVersion
- *	9		ProcessorArchitecture
- *
- * The Windows host expects the Key Name and Key Value to be encoded in utf16.
+ * Types for GPADL, decides is how GPADL header is created.
  *
- * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
- * data gathering functionality in a user mode daemon. The user level daemon
- * is also responsible for binding the key name to the index as well. The
- * kernel and user-level daemon communicate using a connector channel.
+ * It doesn't make much difference between BUFFER and RING if PAGE_SIZE is the
+ * same as HV_HYP_PAGE_SIZE.
  *
- * The user mode component first registers with the
- * the kernel component. Subsequently, the kernel component requests, data
- * for the specified keys. In response to this message the user mode component
- * fills in the value corresponding to the specified key. We overload the
- * sequence field in the cn_msg header to define our KVP message types.
+ * If PAGE_SIZE is bigger than HV_HYP_PAGE_SIZE, the headers of ring buffers
+ * will be of PAGE_SIZE, however, only the first HV_HYP_PAGE will be put
+ * into gpadl, therefore the number for HV_HYP_PAGE and the indexes of each
+ * HV_HYP_PAGE will be different between different types of GPADL, for example
+ * if PAGE_SIZE is 64K:
  *
+ * BUFFER:
  *
- * The kernel component simply acts as a conduit for communication between the
- * Windows host and the user-level daemon. The kernel component passes up the
- * index received from the Host to the user-level daemon. If the index is
- * valid (supported), the corresponding key as well as its
- * value (both are strings) is returned. If the index is invalid
- * (not supported), a NULL key string is returned.

- * As we look at expanding the KVP functionality to include

- *
- * The KVP opcodes are defined by the host and it was unfortunate
- * that I chose to treat the registration operation as part of the
- * KVP operations defined by the host.
- * Here is the level of compatibility
- * (between the user level daemon and the kernel KVP driver) that we
- * will implement:
+ * gva:    |--       64k      --|--       64k      --| ... |

  *
- * An older daemon will always be supported on a newer driver.
- * A given user level daemon will require a minimal version of the
- * kernel driver.
- * If we cannot handle the version differences, we will fail gracefully
- * (this can happen when we have a user level daemon that is more
- * advanced than the KVP driver.
+ * RING:
  *
- * We will use values used in this handshake for determining if we have
- * workable user level daemon and the kernel driver. We begin by taking the
- * registration opcode out of the KVP opcode namespace. We will however,
- * maintain compatibility with the existing user-level daemon code.

-/**
- * struct sx150x_platform_data - config data for SX150x driver
- * @gpio_base: The index number of the first GPIO assigned to this
- *             GPIO expander.  The expander will create a block of
- *             consecutively numbered gpios beginning at the given base,
- *             with the size of the block depending on the model of the
- *             expander chip.
- * @oscio_is_gpo: If set to true, the driver will configure OSCIO as a GPO
- *                instead of as an oscillator, increasing the size of the
- *                GP(I)O pool created by this expander by one.  The
- *                output-only GPO pin will be added at the end of the block.
- * @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor
- *                 for each IO line in the expander.  Setting the bit at
- *                 position n will enable the pull-up for the IO at
- *                 the corresponding offset.  For chips with fewer than
- *                 16 IO pins, high-end bits are ignored.
- * @io_pulldn_ena: A bit-mask which enables-or disables the pull-down
- *                 resistor for each IO line in the expander. Setting the
- *                 bit at position n will enable the pull-down for the IO at
- *                 the corresponding offset.  For chips with fewer than
- *                 16 IO pins, high-end bits are ignored.
- * @io_open_drain_ena: A bit-mask which enables-or disables open-drain
- *                     operation for each IO line in the expander. Setting the
- *                     bit at position n enables open-drain operation for
- *                     the IO at the corresponding offset.  Clearing the bit
- *                     enables regular push-pull operation for that IO.
- *                     For chips with fewer than 16 IO pins, high-end bits
- *                     are ignored.
- * @io_polarity: A bit-mask which enables polarity inversion for each IO line
- *               in the expander.  Setting the bit at position n inverts
- *               the polarity of that IO line, while clearing it results
- *               in normal polarity. For chips with fewer than 16 IO pins,
- *               high-end bits are ignored.
- * @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line
- *               is connected, via which it reports interrupt events
- *               across all GPIO lines.  This must be a real,
- *               pre-existing IRQ line.
- *               Setting this value < 0 disables the irq_chip functionality
- *               of the driver.
- * @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based
- *            IRQ lines will appear.  Similarly to gpio_base, the expander
- *            will create a block of irqs beginning at this number.
- *            This value is ignored if irq_summary is < 0.

+ *	      You can also put controller specific initialization in there.
+ *	      This method is mandatory.
+ * @bus_cleanup: cleanup everything done in
+ *		 &i3c_master_controller_ops->bus_init().
+ *		 This method is optional.
+ * @attach_i3c_dev: called every time an I3C device is attached to the bus. It
+ *		    can be after a DAA or when a device is statically declared
+ *		    by the FW, in which case it will only have a static address
+ *		    and the dynamic address will be 0.
+ *		    When this function is called, device information have not
+ *		    been retrieved yet.
+ *		    This is a good place to attach master controller specific
+ *		    data to I3C devices.
+ *		    This method is optional.
+ * @reattach_i3c_dev: called every time an I3C device has its addressed
+ *		      changed. It can be because the device has been powered
+ *		      down and has lost its address, or it can happen when a
+ *		      device had a static address and has been assigned a
+ *		      dynamic address with SETDASA.
+ *		      This method is optional.
+ * @detach_i3c_dev: called when an I3C device is detached from the bus. Usually
+ *		    happens when the master device is unregistered.
+ *		    This method is optional.
+ * @do_daa: do a DAA (Dynamic Address Assignment) procedure. This is procedure
+ *	    should send an ENTDAA CCC command and then add all devices
+ *	    discovered sure the DAA using i3c_master_add_i3c_dev_locked().
+ *	    Add devices added with i3c_master_add_i3c_dev_locked() will then be
+ *	    attached or re-attached to the controller.
+ *	    This method is mandatory.
+ * @supports_ccc_cmd: should return true if the CCC command is supported, false
+ *		      otherwise.
+ *		      This method is optional, if not provided the core assumes
+ *		      all CCC commands are supported.
+ * @send_ccc_cmd: send a CCC command
+ *		  This method is mandatory.
+ * @priv_xfers: do one or several private I3C SDR transfers
+ *		This method is mandatory.
+ * @attach_i2c_dev: called every time an I2C device is attached to the bus.
+ *		    This is a good place to attach master controller specific
+ *		    data to I2C devices.
+ *		    This method is optional.
+ * @detach_i2c_dev: called when an I2C device is detached from the bus. Usually
+ *		    happens when the master device is unregistered.
+ *		    This method is optional.
+ * @i2c_xfers: do one or several I2C transfers. Note that, unlike i3c
+ *	       transfers, the core does not guarantee that buffers attached to
+ *	       the transfers are DMA-safe. If drivers want to have DMA-safe
+ *	       buffers, they should use the i2c_get_dma_safe_msg_buf()
+ *	       and i2c_put_dma_safe_msg_buf() helpers provided by the I2C
+ *	       framework.
+ *	       This method is mandatory.
+ * @request_ibi: attach an IBI handler to an I3C device. This implies defining
+ *		 an IBI handler and the constraints of the IBI (maximum payload
+ *		 length and number of pre-allocated slots).
+ *		 Some controllers support less IBI-capable devices than regular
+ *		 devices, so this method might return -%EBUSY if there's no
+ *		 more space for an extra IBI registration
+ *		 This method is optional.
+ * @free_ibi: free an IBI previously requested with ->request_ibi(). The IBI
+ *	      should have been disabled with ->disable_irq() prior to that
+ *	      This method is mandatory only if ->request_ibi is not NULL.
+ * @enable_ibi: enable the IBI. Only valid if ->request_ibi() has been called
+ *		prior to ->enable_ibi(). The controller should first enable
+ *		the IBI on the controller end (for example, unmask the hardware
+ *		IRQ) and then send the ENEC CCC command (with the IBI flag set)
+ *		to the I3C device.
+ *		This method is mandatory only if ->request_ibi is not NULL.
+ * @disable_ibi: disable an IBI. First send the DISEC CCC command with the IBI
+ *		 flag set and then deactivate the hardware IRQ on the
+ *		 controller end.
+ *		 This method is mandatory only if ->request_ibi is not NULL.
+ * @recycle_ibi_slot: recycle an IBI slot. Called every time an IBI has been
+ *		      processed by its handler. The IBI slot should be put back
+ *		      in the IBI slot pool so that the controller can re-use it
+ *		      for a future IBI
+ *		      This method is mandatory only if ->request_ibi is not
+ *		      NULL.

+ * 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

+ * iosys_map_rd_field - Read a member from a struct in the iosys_map
+ *
+ * @map__:		The iosys_map structure
+ * @struct_offset__:	Offset from the beggining of the map, where the struct
+ *			is located
+ * @struct_type__:	The struct describing the layout of the mapping
+ * @field__:		Member of the struct to read
+ *
+ * Read a value from iosys_map considering its layout is described by a C struct
+ * starting at @struct_offset__. The field offset and size is calculated and its
+ * value read. If the field access would incur in un-aligned access, then either
+ * iosys_map_memcpy_from() needs to be used or the architecture must support it.
+ * For example: suppose there is a @struct foo defined as below and the value
+ * ``foo.field2.inner2`` needs to be read from the iosys_map:
+ *
+ * .. code-block:: c
+ *
+ *	struct foo {

+ *		struct {
+ *			int inner1;
+ *			int inner2;
+ *		} field2;
+ *		int field3;
+ *	} __packed;
+ *
+ * This is the expected memory layout of a buffer using iosys_map_rd_field():
+ *

+ * The inode->i_version field:
+ * ---------------------------
+ * The change attribute (i_version) is mandated by NFSv4 and is mostly for
+ * knfsd, but is also used for other purposes (e.g. IMA). The i_version must
+ * appear larger to observers if there was an explicit change to the inode's
+ * data or metadata since it was last queried.
+ *
+ * An explicit change is one that would ordinarily result in a change to the
+ * inode status change time (aka ctime). i_version must appear to change, even
+ * if the ctime does not (since the whole point is to avoid missing updates due
+ * to timestamp granularity). If POSIX or other relevant spec mandates that the
+ * ctime must change due to an operation, then the i_version counter must be
+ * incremented as well.
+ *
+ * Making the i_version update completely atomic with the operation itself would
+ * be prohibitively expensive. Traditionally the kernel has updated the times on
+ * directories after an operation that changes its contents. For regular files,
+ * the ctime is usually updated before the data is copied into the cache for a
+ * write. This means that there is a window of time when an observer can
+ * associate a new timestamp with old file contents. Since the purpose of the
+ * i_version is to allow for better cache coherency, the i_version must always
+ * be updated after the results of the operation are visible. Updating it before
+ * and after a change is also permitted. (Note that no filesystems currently do
+ * this. Fixing that is a work-in-progress).
+ *
+ * Observers see the i_version as a 64-bit number that never decreases. If it
+ * remains the same since it was last checked, then nothing has changed in the
+ * inode. If it's different then something has changed. Observers cannot infer
+ * anything about the nature or magnitude of the changes from the value, only
+ * that the inode has changed in some fashion.
+ *
+ * Not all filesystems properly implement the i_version counter. Subsystems that
+ * want to use i_version field on an inode should first check whether the
+ * filesystem sets the SB_I_VERSION flag (usually via the IS_I_VERSION macro).
+ *
+ * Those that set SB_I_VERSION will automatically have their i_version counter
+ * incremented on writes to normal files. If the SB_I_VERSION is not set, then
+ * the VFS will not touch it on writes, and the filesystem can use it how it
+ * wishes. Note that the filesystem is always responsible for updating the
+ * i_version on namespace changes in directories (mkdir, rmdir, unlink, etc.).
+ * We consider these sorts of filesystems to have a kernel-managed i_version.
+ *
+ * It may be impractical for filesystems to keep i_version updates atomic with
+ * respect to the changes that cause them.  They should, however, guarantee
+ * that i_version updates are never visible before the changes that caused
+ * them.  Also, i_version updates should never be delayed longer than it takes
+ * the original change to reach disk.
+ *
+ * This implementation uses the low bit in the i_version field as a flag to
+ * track when the value has been queried. If it has not been queried since it
+ * was last incremented, we can skip the increment in most cases.
+ *
+ * In the event that we're updating the ctime, we will usually go ahead and
+ * bump the i_version anyway. Since that has to go to stable storage in some
+ * fashion, we might as well increment it as well.
+ *
+ * With this implementation, the value should always appear to observers to
+ * increase over time if the file has changed. It's recommended to use
+ * inode_eq_iversion() helper to compare values.
+ *
+ * Note that some filesystems (e.g. NFS and AFS) just use the field to store
+ * a server-provided value (for the most part). For that reason, those
+ * filesystems do not set SB_I_VERSION. These filesystems are considered to
+ * have a self-managed i_version.
+ *
+ * Persistently storing the i_version
+ * ----------------------------------
+ * Queries of the i_version field are not gated on them hitting the backing
+ * store. It's always possible that the host could crash after allowing
+ * a query of the value but before it has made it to disk.
+ *
+ * To mitigate this problem, filesystems should always use
+ * inode_set_iversion_queried when loading an existing inode from disk. This
+ * ensures that the next attempted inode increment will result in the value
+ * changing.
+ *
+ * Storing the value to disk therefore does not count as a query, so those
+ * filesystems should use inode_peek_iversion to grab the value to be stored.
+ * There is no need to flag the value as having been queried in that case.
+ */
+
+/*
+ * We borrow the lowest bit in the i_version to use as a flag to tell whether

+ *
+ * At runtime we can change the branch target by setting the key

+ * the key or branch direction via static_branch_{inc,dec}. Thus,
+ * static_branch_inc() can be thought of as a 'make more true' and

+ * Only the bits set in @mask are checked for concurrent modifications, while
+ * ignoring the remaining bits, i.e. concurrent writes (or reads) to ~mask bits
+ * are ignored.
+ *
+ * Use this for variables, where some bits must not be modified concurrently,
+ * yet other bits are expected to be modified concurrently.
+ *
+ * For example, variables where, after initialization, some bits are read-only,
+ * but other bits may still be modified concurrently. A reader may wish to
+ * assert that this is true as follows:
+ *
+ * .. code-block:: c
+ *
+ *	ASSERT_EXCLUSIVE_BITS(flags, READ_ONLY_MASK);
+ *	foo = (READ_ONCE(flags) & READ_ONLY_MASK) >> READ_ONLY_SHIFT;
+ *
+ * Note: The access that immediately follows ASSERT_EXCLUSIVE_BITS() is assumed
+ * to access the masked bits only, and KCSAN optimistically assumes it is
+ * therefore safe, even in the presence of data races, and marking it with
+ * READ_ONCE() is optional from KCSAN's point-of-view. We caution, however, that
+ * it may still be advisable to do so, since we cannot reason about all compiler
+ * optimizations when it comes to bit manipulations (on the reader and writer
+ * side). If you are sure nothing can go wrong, we can write the above simply
+ * as:
+ *
+ * .. code-block:: c
+ *
+ *	ASSERT_EXCLUSIVE_BITS(flags, READ_ONLY_MASK);
+ *	foo = (flags & READ_ONLY_MASK) >> READ_ONLY_SHIFT;
+ *
+ * Another example, where this may be used, is when certain bits of @var may
+ * only be modified when holding the appropriate lock, but other bits may still
+ * be modified concurrently. Writers, where other bits may change concurrently,
+ * could use the assertion as follows:
+ *
+ * .. code-block:: c
+ *
+ *	spin_lock(&foo_lock);
+ *	ASSERT_EXCLUSIVE_BITS(flags, FOO_MASK);
+ *	old_flags = flags;
+ *	new_flags = (old_flags & ~FOO_MASK) | (new_foo << FOO_SHIFT);
+ *	if (cmpxchg(&flags, old_flags, new_flags) != old_flags) { ... }
+ *	spin_unlock(&foo_lock);
+ *
+ * @var: variable to assert on
+ * @mask: only check for modifications to bits set in @mask

+ * and having a very large hash table would waste memory.
+ *
+ * At the moment size of hash table of locks is being set based on
+ * the number of CPUs as follows:
+ *
+ * NR_CPU      NR_KERNFS_LOCK_BITS      NR_KERNFS_LOCKS
+ *   1                  1                       2

+ *  4-7                 4                       16
+ *  8-15                6                       64
+ *  16-31               8                       256
+ *  32 and more         10                      1024
+ *
+ * The above relation between NR_CPU and number of locks is based
+ * on some internal experimentation which involved booting qemu
+ * with different values of smp, performing some sysfs operations
+ * on all CPUs and observing how increase in number of locks impacts
+ * completion time of these sysfs operations on each CPU.

- * ktime_t:

- * On 64-bit CPUs a single 64-bit variable is used to store the hrtimers
- * internal representation of time values in scalar nanoseconds. The
- * design plays out best on 64-bit CPUs, where most conversions are
- * NOPs and most arithmetic ktime_t operations are plain arithmetic
- * operations.
- *
- * On 32-bit CPUs an optimized representation of the timespec structure
- * is used to avoid expensive conversions from and to timespecs. The
- * endian-aware order of the tv struct members is chosen to allow
- * mathematical operations on the tv64 member of the union too, which
- * for certain operations produces better code.
- *
- * For architectures with efficient support for 64/32-bit conversions the
- * plain scalar nanosecond based representation can be selected by the
- * config switch CONFIG_KTIME_SCALAR.

- * Virtio devices are also used by kvm, so we can simply reuse their optimized
- * device drivers.  And one day when everyone uses virtio, my plan will be

+ * @startup:	Called when a client requests the chan. The controller
+ *		could ask clients for additional parameters of communication
+ *		to be provided via client's chan_data. This call may
+ *		block. After this call the Controller must forward any
+ *		data received on the chan by calling mbox_chan_received_data.

+ * @last_tx_done: If the controller sets 'txdone_poll', the API calls
+ *		  this to poll status of last TX. The controller must
+ *		  give priority to IRQ method over polling and never
+ *		  set both txdone_poll and txdone_irq. Only in polling
+ *		  mode 'send_data' is expected to return -EBUSY.

+ *
+ * MEMORY_DEVICE_COHERENT:
+ * Device memory that is cache coherent from device and CPU point of view. This
+ * is used on platforms that have an advanced system bus (like CAPI or CXL). A
+ * driver can hotplug the device memory using ZONE_DEVICE and with that memory
+ * type. Any page of a process can be migrated to such memory. However no one
+ * should be allowed to pin such memory so that it can always be evicted.
+ *
+ * MEMORY_DEVICE_FS_DAX:
+ * Host memory that has similar access semantics as System RAM i.e. DMA
+ * coherent and supports page pinning. In support of coordinating page
+ * pinning vs other operations MEMORY_DEVICE_FS_DAX arranges for a
+ * wakeup event whenever a page is unpinned and becomes idle. This
+ * wakeup is used to coordinate physical address space management (ex:
+ * fs truncate/hole punch) vs pinned pages (ex: device dma).
+ *
+ * MEMORY_DEVICE_GENERIC:
+ * Host memory that has similar access semantics as System RAM i.e. DMA
+ * coherent and supports page pinning. This is for example used by DAX devices

+ *  - Over voltage detection
+ *  - Under voltage detection
+ *  - Under voltage protection
+ *  - 'system interrupt'.
+ *
+ * Each of the blocks have a status register giving more accurate IRQ source
+ * information - for example which of the regulators have over-voltage.
+ *
+ * On top of this, there is "main IRQ" status register where each bit indicates
+ * which of sub-blocks have active IRQs. Fine. That would fit regmap-irq main
+ * status handling. Except that:
+ *  - Only some sub-IRQs can be masked.
+ *  - The IRQ informs us about fault-condition, not when fault state changes.
+ *    The IRQ line it is kept asserted until the detected condition is acked
+ *    AND cleared in HW. This is annoying for IRQs like the one informing high
+ *    temperature because if IRQ is not disabled it keeps the CPU in IRQ
+ *    handling loop.
+ *
+ * For now we do just use the main-IRQ register as source for our IRQ
+ * information and bind the regmap-irq to this. We leave fine-grained sub-IRQ
+ * register handling to handlers in sub-devices. The regulator driver shall
+ * read which regulators are source for problem - or if the detected error is
+ * regulator temperature error. The sub-drivers do also handle masking of "sub-
+ * IRQs" if this is supported/needed.
+ *
+ * To overcome the problem with HW keeping IRQ asserted we do call
+ * disable_irq_nosync() from sub-device handler and add a delayed work to
+ * re-enable IRQ roughly 1 second later. This should keep our CPU out of
+ * busy-loop.

+ *                        We should only access orig_pte if this flag set.
+ * @FAULT_FLAG_VMA_LOCK: The fault is handled under VMA lock.
+ *
+ * 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
+ *                              this is the first try
+ *
+ * (b) 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
+ * interrupted if necessary.
+ *
+ * The combination FAULT_FLAG_WRITE|FAULT_FLAG_UNSHARE is illegal.
+ * FAULT_FLAG_UNSHARE is ignored and treated like an ordinary read fault when
+ * applied to mappings that are not COW mappings.

+ * FOLL_PIN and FOLL_LONGTERM may be used in various combinations with each
+ * other. Here is what they mean, and how to use them:
+ *
+ *
+ * FIXME: For pages which are part of a filesystem, mappings are subject to the
+ * lifetime enforced by the filesystem and we need guarantees that longterm
+ * users like RDMA and V4L2 only establish mappings which coordinate usage with
+ * the filesystem.  Ideas for this coordination include revoking the longterm
+ * pin, delaying writeback, bounce buffer page writeback, etc.  As FS DAX was
+ * added after the problem with filesystems was found FS DAX VMAs are
+ * specifically failed.  Filesystem pages are still subject to bugs and use of
+ * FOLL_LONGTERM should be avoided on those pages.
+ *
+ * In the CMA case: long term pins in a CMA region would unnecessarily fragment
+ * that region.  And so, CMA attempts to migrate the page before pinning, when
+ * FOLL_LONGTERM is specified.
+ *
+ * FOLL_PIN indicates that a special kind of tracking (not just page->_refcount,
+ * but an additional pin counting system) will be invoked. This is intended for
+ * anything that gets a page reference and then touches page data (for example,
+ * Direct IO). This lets the filesystem know that some non-file-system entity is
+ * potentially changing the pages' data. In contrast to FOLL_GET (whose pages
+ * are released via put_page()), FOLL_PIN pages must be released, ultimately, by
+ * a call to unpin_user_page().
+ *
+ * FOLL_PIN is similar to FOLL_GET: both of these pin pages. They use different
+ * and separate refcounting mechanisms, however, and that means that each has
+ * its own acquire and release mechanisms:
+ *
+ *     FOLL_GET: get_user_pages*() to acquire, and put_page() to release.
+ *
+ *     FOLL_PIN: pin_user_pages*() to acquire, and unpin_user_pages to release.
+ *
+ * FOLL_PIN and FOLL_GET are mutually exclusive for a given function call.
+ * (The underlying pages may experience both FOLL_GET-based and FOLL_PIN-based
+ * calls applied to them, and that's perfectly OK. This is a constraint on the
+ * callers, not on the pages.)
+ *
+ * FOLL_PIN should be set internally by the pin_user_pages*() APIs, never
+ * directly by the caller. That's in order to help avoid mismatches when
+ * releasing pages: get_user_pages*() pages must be released via put_page(),
+ * while pin_user_pages*() pages must be released via unpin_user_page().
+ *
+ * Please see Documentation/core-api/pin_user_pages.rst for more information.

- * Locking
- * =======
- *
- * @lock is a softirq-safe spinlock protecting @queue as well as
- * @cur_slot, @mrq and @state. These must always be updated
- * at the same time while holding @lock.
- *
- * The @mrq field of struct dw_mci_slot is also protected by @lock,
- * and must always be written at the same time as the slot is added to
- * @queue.
- *
- * @pending_events and @completed_events are accessed using atomic bit
- * operations, so they don't need any locking.
- *
- * None of the fields touched by the interrupt handler need any
- * locking. However, ordering is important: Before EVENT_DATA_ERROR or
- * EVENT_DATA_COMPLETE is set in @pending_events, all data-related
- * interrupts must be disabled and @data_status updated with a
- * snapshot of SR. Similarly, before EVENT_CMD_COMPLETE is set, the
- * CMDRDY interrupt must be disabled and @cmd_status updated with a
- * snapshot of SR, and before EVENT_XFER_COMPLETE can be set, the
- * bytes_xfered field of @data must be written. This is ensured by
- * using barriers.

+	 * ZONE_MOVABLE is similar to ZONE_NORMAL, except that it contains

+	 * cases for ZONE_MOVABLE are to make memory offlining/unplug more
+	 * likely to succeed, and to locally limit unmovable allocations - e.g.,
+	 * to increase the number of THP/huge pages. Notable special cases are:
+	 *
+	 * 1. Pinned pages: (long-term) pinning of movable pages might
+	 *    essentially turn such pages unmovable. Therefore, we do not allow
+	 *    pinning long-term pages in ZONE_MOVABLE. When pages are pinned and
+	 *    faulted, they come from the right zone right away. However, it is
+	 *    still possible that address space already has pages in
+	 *    ZONE_MOVABLE at the time when pages are pinned (i.e. user has
+	 *    touches that memory before pinning). In such case we migrate them
+	 *    to a different zone. When migration fails - pinning fails.
+	 * 2. memblock allocations: kernelcore/movablecore setups might create
+	 *    situations where ZONE_MOVABLE contains unmovable allocations
+	 *    after boot. Memory offlining and allocations fail early.
+	 * 3. Memory holes: kernelcore/movablecore setups might create very rare
+	 *    situations where ZONE_MOVABLE contains memory holes after boot,
+	 *    for example, if we have sections that are only partially
+	 *    populated. Memory offlining and allocations fail early.
+	 * 4. PG_hwpoison pages: while poisoned pages can be skipped during
+	 *    memory offlining, such pages cannot be allocated.
+	 * 5. Unmovable PG_offline pages: in paravirtualized environments,
+	 *    hotplugged memory blocks might only partially be managed by the
+	 *    buddy (e.g., via XEN-balloon, Hyper-V balloon, virtio-mem). The
+	 *    parts not manged by the buddy are unmovable PG_offline pages. In
+	 *    some cases (virtio-mem), such pages can be skipped during
+	 *    memory offlining, however, cannot be moved/allocated. These
+	 *    techniques might use alloc_contig_range() to hide previously
+	 *    exposed pages from the buddy again (e.g., to implement some sort
+	 *    of memory unplug in virtio-mem).
+	 * 6. ZERO_PAGE(0), kernelcore/movablecore setups might create
+	 *    situations where ZERO_PAGE(0) which is allocated differently
+	 *    on different platforms may end up in a movable zone. ZERO_PAGE(0)
+	 *    cannot be migrated.
+	 * 7. Memory-hotplug: when using memmap_on_memory and onlining the
+	 *    memory to the MOVABLE zone, the vmemmap pages are also placed in
+	 *    such zone. Such pages cannot be really moved around as they are
+	 *    self-stored in the range, but they are treated as movable when
+	 *    the range they describe is about to be offlined.
+	 *
+	 * In general, no unmovable allocations that degrade memory offlining
+	 * should end up in ZONE_MOVABLE. Allocators (like alloc_contig_range())
+	 * have to expect that migrating pages in ZONE_MOVABLE can fail (even
+	 * if has_unmovable_pages() states that there are no unmovable pages,
+	 * there can be false negatives).

- * We cache key information from each zonelist for smaller cache

- *
- * 1) The BITMAP fullzones tracks which zones in a zonelist have come
- *    up short of free memory since the last time (last_fullzone_zap)
- *    we zero'd fullzones.
- * 2) The array z_to_n[] maps each zone in the zonelist to its node
- *    id, so that we can efficiently evaluate whether that node is
- *    set in the current tasks mems_allowed.
- *
- * Both fullzones and z_to_n[] are one-to-one with the zonelist,
- * indexed by a zones offset in the zonelist zones[] array.
- *
- * The get_page_from_freelist() routine does two scans.  During the
- * first scan, we skip zones whose corresponding bit in 'fullzones'
- * is set or whose corresponding node in current->mems_allowed (which
- * comes from cpusets) is not set.  During the second scan, we bypass
- * this zonelist_cache, to ensure we look methodically at each zone.
- *
- * Once per second, we zero out (zap) fullzones, forcing us to
- * reconsider nodes that might have regained more free memory.
- * The field last_full_zap is the time we last zapped fullzones.
- *
- * This mechanism reduces the amount of time we waste repeatedly
- * reexaming zones for free memory when they just came up low on
- * memory momentarilly ago.
- *
- * The zonelist_cache struct members logically belong in struct
- * zonelist.  However, the mempolicy zonelists constructed for
- * MPOL_BIND are intentionally variable length (and usually much
- * shorter).  A general purpose mechanism for handling structs with
- * multiple variable length members is more mechanism than we want
- * here.  We resort to some special case hackery instead.
- *
- * The MPOL_BIND zonelists don't need this zonelist_cache (in good
- * part because they are shorter), so we put the fixed length stuff
- * at the front of the zonelist struct, ending in a variable length
- * zones[], as is needed by MPOL_BIND.
- *
- * Then we put the optional zonelist cache on the end of the zonelist
- * struct.  This optional stuff is found by a 'zlcache_ptr' pointer in
- * the fixed length portion at the front of the struct.  This pointer
- * both enables us to find the zonelist cache, and in the case of
- * MPOL_BIND zonelists, (which will just set the zlcache_ptr to NULL)
- * to know that the zonelist cache is not there.
- *
- * The end result is that struct zonelists come in two flavors:
- *  1) The full, fixed length version, shown below, and
- *  2) The custom zonelists for MPOL_BIND.
- * The custom MPOL_BIND zonelists have a NULL zlcache_ptr and no zlcache.
- *
- * Even though there may be multiple CPU cores on a node modifying
- * fullzones or last_full_zap in the same zonelist_cache at the same
- * time, we don't lock it.  This is just hint data - if it is wrong now
- * and then, the allocator will still function, perhaps a bit slower.

+ *
+ * 2) Implied protection: there is an implied protection against module
+ *    removal. An example of this is the implied protection used by kernfs /
+ *    sysfs. The sysfs store / read file operations are guaranteed to exist
+ *    through the use of kernfs's active reference (see kernfs_active()) and a
+ *    sysfs / kernfs file removal cannot happen unless the same file is not
+ *    active. Therefore, if a sysfs file is being read or written to the module
+ *    which created it must still exist. It is therefore safe to use
+ *    try_module_get() on module sysfs store / read ops.
+ *
+ * One of the real values to try_module_get() is the module_is_live() check
+ * which ensures that the caller of try_module_get() can yield to userspace
+ * module removal requests and gracefully fail if the module is on its way out.

+ *            transport routine. As such, the structure represents the
+ *            FC exchange context for the NVME-FC LS request that was
+ *            received and which the response is to be sent for.
+ *            Used by the LLDD to pass the nvmet-fc transport (controller)

+ *              and Disconnect Association.

+ *              received LS's such as Disconnect Association or Disconnect
+ *              Connection.
+ *
+ * The structure is allocated by the LLDD whenever a LS Request is received
+ * from the FC link. The address of the structure is passed to the nvmet-fc
+ * or nvme-fc layer via the xxx_rcv_ls_req() transport routines.
+ *
+ * The address of the structure is to be passed back to the LLDD
+ * when the response is to be transmit. The LLDD will use the address to
+ * map back to the LLDD exchange structure which maintains information such
+ * the remote N_Port that sent the LS as well as any FC exchange context.
+ * Upon completion of the LS response transmit, the LLDD will pass the
+ * address of the structure back to the transport LS rsp done() routine,
+ * allowing the transport release dma resources. Upon completion of
+ * the done() routine, no further access to the structure will be made by
+ * the transport and the LLDD can de-allocate the structure.

+ *       command that is posted to the controller queue.  The handle can
+ *       be used by the LLDD to map quickly to the proper hw queue for
+ *       command execution.  The mask of cpu's that will map to this queue
+ *       at the block-level is also passed in. The LLDD should use the
+ *       queue id and/or cpu masks to ensure proper affinitization of the
+ *       controller queue to the hw queue.
+ *       Entrypoint is Optional.
+ *
+ * @delete_queue:  This is the inverse of the crete_queue. During
+ *       host<->controller association teardown, this routine is called
+ *       when a controller queue is being terminated. Any association with
+ *       a hw queue should be termined. If there is a unique hw queue, the
+ *       hw queue should be torn down.
+ *       Entrypoint is Optional.
+ *
+ * @poll_queue:  Called to poll for the completion of an io on a blk queue.
+ *       Entrypoint is Optional.
+ *
+ * @ls_req:  Called to issue a FC-NVME FC-4 LS service request.
+ *       The nvme_fc_ls_req structure will fully describe the buffers for
+ *       the request payload and where to place the response payload. The
+ *       LLDD is to allocate an exchange, issue the LS request, obtain the
+ *       LS response, and call the "done" routine specified in the request
+ *       structure (argument to done is the ls request structure itself).
+ *       Entrypoint is Mandatory.
+ *
+ * @fcp_io:  called to issue a FC-NVME I/O request.  The I/O may be for
+ *       an admin queue or an i/o queue.  The nvmefc_fcp_req structure will
+ *       fully describe the io: the buffer containing the FC-NVME CMD IU
+ *       (which contains the SQE), the sg list for the payload if applicable,
+ *       and the buffer to place the FC-NVME RSP IU into.  The LLDD will
+ *       complete the i/o, indicating the amount of data transferred or
+ *       any transport error, and call the "done" routine specified in the
+ *       request structure (argument to done is the fcp request structure
+ *       itself).
+ *       Entrypoint is Mandatory.
+ *
+ * @ls_abort: called to request the LLDD to abort the indicated ls request.
+ *       The call may return before the abort has completed. After aborting
+ *       the request, the LLDD must still call the ls request done routine
+ *       indicating an FC transport Aborted status.
+ *       Entrypoint is Mandatory.
+ *
+ * @fcp_abort: called to request the LLDD to abort the indicated fcp request.
+ *       The call may return before the abort has completed. After aborting
+ *       the request, the LLDD must still call the fcp request done routine
+ *       indicating an FC transport Aborted status.
+ *       Entrypoint is Mandatory.
+ *
+ * @xmt_ls_rsp:  Called to transmit the response to a FC-NVME FC-4 LS service.
+ *       The nvmefc_ls_rsp structure is the same LLDD-supplied exchange
+ *       structure specified in the nvme_fc_rcv_ls_req() call made when
+ *       the LS request was received. The structure will fully describe
+ *       the buffers for the response payload and the dma address of the
+ *       payload. The LLDD is to transmit the response (or return a
+ *       non-zero errno status), and upon completion of the transmit, call
+ *       the "done" routine specified in the nvmefc_ls_rsp structure
+ *       (argument to done is the address of the nvmefc_ls_rsp structure
+ *       itself). Upon the completion of the done routine, the LLDD shall
+ *       consider the LS handling complete and the nvmefc_ls_rsp structure
+ *       may be freed/released.
+ *       Entrypoint is mandatory if the LLDD calls the nvme_fc_rcv_ls_req()
+ *       entrypoint.
+ *
+ * @max_hw_queues:  indicates the maximum number of hw queues the LLDD
+ *       supports for cpu affinitization.
+ *       Value is Mandatory. Must be at least 1.
+ *
+ * @max_sgl_segments:  indicates the maximum number of sgl segments supported

+ *       Value is Mandatory. Must be at least 1. Recommend at least 256.
+ *
+ * @max_dif_sgl_segments:  indicates the maximum number of sgl segments
+ *       supported by the LLDD for DIF operations.
+ *       Value is Mandatory. Must be at least 1. Recommend at least 256.
+ *
+ * @dma_boundary:  indicates the dma address boundary where dma mappings
+ *       will be split across.
+ *       Value is Mandatory. Typical value is 0xFFFFFFFF to split across
+ *       4Gig address boundarys
+ *
+ * @local_priv_sz: The LLDD sets this field to the amount of additional
+ *       memory that it would like fc nvme layer to allocate on the LLDD's
+ *       behalf whenever a localport is allocated.  The additional memory
+ *       area solely for the of the LLDD and its location is specified by

+ *           may call the READDATA operation multiple times for longer
+ *           payloads.
+ *         NVMET_FCOP_WRITEDATA operation: the LLDD is to receive the
+ *           payload data (described by sglist) from the host via 1 or
+ *           more FC sequences (preferrably 1). The LLDD is to generate
+ *           the XFER_RDY IU(s) corresponding to the data being requested.
+ *           Note: the FC-NVME layer may call the WRITEDATA operation
+ *           multiple times for longer payloads.

+ *           FCP_RSP iu payload (described by rspbuf, rspdma, rsplen).
+ *           If FCP_CONF is supported, the LLDD is to await FCP_CONF
+ *           reception to confirm the RSP reception by the host. The LLDD
+ *           may retramsit the FCP_RSP iu if necessary per FC-NVME. Upon
+ *           transmission of the FCP_RSP iu if FCP_CONF is not supported,
+ *           or upon success/failure of FCP_CONF if it is supported, the
+ *           LLDD is to set the nvmefc_tgt_fcp_req fcp_error field and
+ *           consider the operation complete.
+ *         NVMET_FCOP_RSP: the LLDD is to transmit the FCP_RSP iu payload
+ *           (described by rspbuf, rspdma, rsplen). If FCP_CONF is
+ *           supported, the LLDD is to await FCP_CONF reception to confirm
+ *           the RSP reception by the host. The LLDD may retramsit the
+ *           FCP_RSP iu if FCP_CONF is not received per FC-NVME. Upon
+ *           transmission of the FCP_RSP iu if FCP_CONF is not supported,
+ *           or upon success/failure of FCP_CONF if it is supported, the
+ *           LLDD is to set the nvmefc_tgt_fcp_req fcp_error field and
+ *           consider the operation complete.
+ *       Upon completing the indicated operation, the LLDD is to set the
+ *       status fields for the operation (tranferred_length and fcp_error
+ *       status) in the request, then call the "done" routine
+ *       indicated in the fcp request. After the operation completes,
+ *       regardless of whether the FCP_RSP iu was successfully transmit,
+ *       the LLDD-supplied exchange structure must remain valid until the
+ *       transport calls the fcp_req_release() callback to return ownership
+ *       of the exchange structure back to the LLDD so that it may be used
+ *       for another fcp command.
+ *       Note: when calling the done routine for READDATA or WRITEDATA
+ *       operations, the fc-nvme layer may immediate convert, in the same
+ *       thread and before returning to the LLDD, the fcp operation to
+ *       the next operation for the fcp io and call the LLDDs fcp_op
+ *       call again. If fields in the fcp request are to be accessed post
+ *       the done call, the LLDD should save their values prior to calling
+ *       the done routine, and inspect the save values after the done
+ *       routine.
+ *       Returns 0 on success, -<errno> on failure (Ex: -EIO)
+ *       Entrypoint is Mandatory.
+ *
+ * @fcp_abort:  Called by the transport to abort an active command.
+ *       The command may be in-between operations (nothing active in LLDD)
+ *       or may have an active WRITEDATA operation pending. The LLDD is to
+ *       initiate the ABTS process for the command and return from the
+ *       callback. The ABTS does not need to be complete on the command.
+ *       The fcp_abort callback inherently cannot fail. After the
+ *       fcp_abort() callback completes, the transport will wait for any
+ *       outstanding operation (if there was one) to complete, then will
+ *       call the fcp_req_release() callback to return the command's
+ *       exchange context back to the LLDD.
+ *       Entrypoint is Mandatory.
+ *
+ * @fcp_req_release:  Called by the transport to return a nvmefc_tgt_fcp_req
+ *       to the LLDD after all operations on the fcp operation are complete.
+ *       This may be due to the command completing or upon completion of
+ *       abort cleanup.
+ *       Entrypoint is Mandatory.
+ *
+ * @defer_rcv:  Called by the transport to signal the LLLD that it has
+ *       begun processing of a previously received NVME CMD IU. The LLDD
+ *       is now free to re-use the rcv buffer associated with the
+ *       nvmefc_tgt_fcp_req.
+ *       Entrypoint is Optional.
+ *
+ * @discovery_event:  Called by the transport to generate an RSCN
+ *       change notifications to NVME initiators. The RSCN notifications
+ *       should cause the initiator to rescan the discovery controller
+ *       on the targetport.
+ *
+ * @ls_req:  Called to issue a FC-NVME FC-4 LS service request.
+ *       The nvme_fc_ls_req structure will fully describe the buffers for
+ *       the request payload and where to place the response payload.
+ *       The targetport that is to issue the LS request is identified by
+ *       the targetport argument.  The remote port that is to receive the
+ *       LS request is identified by the hosthandle argument. The nvmet-fc
+ *       transport is only allowed to issue FC-NVME LS's on behalf of an
+ *       association that was created prior by a Create Association LS.
+ *       The hosthandle will originate from the LLDD in the struct
+ *       nvmefc_ls_rsp structure for the Create Association LS that
+ *       was delivered to the transport. The transport will save the
+ *       hosthandle as an attribute of the association.  If the LLDD
+ *       loses connectivity with the remote port, it must call the
+ *       nvmet_fc_invalidate_host() routine to remove any references to
+ *       the remote port in the transport.
+ *       The LLDD is to allocate an exchange, issue the LS request, obtain
+ *       the LS response, and call the "done" routine specified in the
+ *       request structure (argument to done is the ls request structure
+ *       itself).
+ *       Entrypoint is Optional - but highly recommended.
+ *
+ * @ls_abort: called to request the LLDD to abort the indicated ls request.
+ *       The call may return before the abort has completed. After aborting
+ *       the request, the LLDD must still call the ls request done routine
+ *       indicating an FC transport Aborted status.
+ *       Entrypoint is Mandatory if the ls_req entry point is specified.
+ *
+ * @host_release: called to inform the LLDD that the request to invalidate
+ *       the host port indicated by the hosthandle has been fully completed.
+ *       No associations exist with the host port and there will be no
+ *       further references to hosthandle.
+ *       Entrypoint is Mandatory if the lldd calls nvmet_fc_invalidate_host().
+ *
+ * @max_hw_queues:  indicates the maximum number of hw queues the LLDD
+ *       supports for cpu affinitization.
+ *       Value is Mandatory. Must be at least 1.
+ *
+ * @max_sgl_segments:  indicates the maximum number of sgl segments supported
+ *       by the LLDD
+ *       Value is Mandatory. Must be at least 1. Recommend at least 256.
+ *
+ * @max_dif_sgl_segments:  indicates the maximum number of sgl segments
+ *       supported by the LLDD for DIF operations.
+ *       Value is Mandatory. Must be at least 1. Recommend at least 256.
+ *
+ * @dma_boundary:  indicates the dma address boundary where dma mappings
+ *       will be split across.
+ *       Value is Mandatory. Typical value is 0xFFFFFFFF to split across
+ *       4Gig address boundarys
+ *
+ * @target_features: The LLDD sets bits in this field to correspond to
+ *       optional features that are supported by the LLDD.
+ *       Refer to the NVMET_FCTGTFEAT_xxx values.
+ *       Value is Mandatory. Allowed to be zero.
+ *
+ * @target_priv_sz: The LLDD sets this field to the amount of additional
+ *       memory that it would like fc nvme layer to allocate on the LLDD's
+ *       behalf whenever a targetport is allocated.  The additional memory
+ *       area solely for the of the LLDD and its location is specified by
+ *       the targetport->private pointer.
+ *       Value is Mandatory. Allowed to be zero.
+ *
+ * @lsrqst_priv_sz: The LLDD sets this field to the amount of additional
+ *       memory that it would like nvmet-fc layer to allocate on the LLDD's
+ *       behalf whenever a ls request structure is allocated. The additional
+ *       memory area is solely for use by the LLDD and its location is
+ *       specified by the ls_request->private pointer.
+ *       Value is Mandatory. Allowed to be zero.

+ * - Pages part of an offline section (struct pages of offline sections should

- * speculatively take a reference to a page.

- *
- * This function must be called inside the same rcu_read_lock() section as has
- * been used to lookup the page in the pagecache radix-tree (or page table):
- * this allows allocators to use a synchronize_rcu() to stabilize _count.
- *
- * Unless an RCU grace period has passed, the count of all pages coming out
- * of the allocator must be considered unstable. page_count may return higher
- * than expected, and put_page must be able to do the right thing when the
- * page has been finished with, no matter what it is subsequently allocated
- * for (because put_page is what is used here to drop an invalid speculative
- * reference).
- *
- * This is the interesting part of the lockless pagecache (and lockless
- * get_user_pages) locking protocol, where the lookup-side (eg. find_get_page)
- * has the following pattern:
- * 1. find page in radix tree
- * 2. conditionally increment refcount
- * 3. check the page is still in pagecache (if no, goto 1)
- *
- * Remove-side that cares about stability of _count (eg. reclaim) has the
- * following (with tree_lock held for write):
- * A. atomically check refcount is correct and set it to 0 (atomic_cmpxchg)
- * B. remove page from pagecache
- * C. free the page
- *
- * There are 2 critical interleavings that matter:
- * - 2 runs before A: in this case, A sees elevated refcount and bails out
- * - A runs before 2: in this case, 2 sees zero refcount and retries;
- *   subsequently, B will complete and 1 will find no page, causing the
- *   lookup to return NULL.
- *
- * It is possible that between 1 and 2, the page is removed then the exact same
- * page is inserted into the same position in pagecache. That's OK: the
- * old find_get_page using tree_lock could equally have run before or after
- * such a re-insertion, depending on order that locks are granted.
- *
- * Lookups racing against pagecache insertion isn't a big problem: either 1

+/**
+ * struct pci_driver - PCI driver structure
+ * @node:	List of driver structures.
+ * @name:	Driver name.
+ * @id_table:	Pointer to table of device IDs the driver is
+ *		interested in.  Most drivers should export this
+ *		table using MODULE_DEVICE_TABLE(pci,...).
+ * @probe:	This probing function gets called (during execution
+ *		of pci_register_driver() for already existing
+ *		devices or later if a new device gets inserted) for
+ *		all PCI devices which match the ID table and are not
+ *		"owned" by the other drivers yet. This function gets
+ *		passed a "struct pci_dev \*" for each device whose
+ *		entry in the ID table matches the device. The probe
+ *		function returns zero when the driver chooses to
+ *		take "ownership" of the device or an error code
+ *		(negative number) otherwise.
+ *		The probe function always gets called from process
+ *		context, so it can sleep.
+ * @remove:	The remove() function gets called whenever a device
+ *		being handled by this driver is removed (either during
+ *		deregistration of the driver or when it's manually
+ *		pulled out of a hot-pluggable slot).
+ *		The remove function always gets called from process
+ *		context, so it can sleep.
+ * @suspend:	Put device into low power state.
+ * @resume:	Wake device from low power state.
+ *		(Please see Documentation/power/pci.rst for descriptions
+ *		of PCI Power Management and the related functions.)
+ * @shutdown:	Hook into reboot_notifier_list (kernel/sys.c).
+ *		Intended to stop any idling DMA operations.
+ *		Useful for enabling wake-on-lan (NIC) or changing
+ *		the power state of a device before reboot.
+ *		e.g. drivers/net/e100.c.
+ * @sriov_configure: Optional driver callback to allow configuration of
+ *		number of VFs to enable via sysfs "sriov_numvfs" file.
+ * @sriov_set_msix_vec_count: PF Driver callback to change number of MSI-X
+ *              vectors on a VF. Triggered via sysfs "sriov_vf_msix_count".
+ *              This will change MSI-X Table Size in the VF Message Control
+ *              registers.
+ * @sriov_get_vf_total_msix: PF driver callback to get the total number of
+ *              MSI-X vectors available for distribution to the VFs.
+ * @err_handler: See Documentation/PCI/pci-error-recovery.rst
+ * @groups:	Sysfs attribute groups.
+ * @dev_groups: Attributes attached to the device that will be
+ *              created once it is bound to the driver.
+ * @driver:	Driver model structure.
+ * @dynids:	List of dynamically added device IDs.
+ * @driver_managed_dma: Device driver doesn't use kernel DMA API for DMA.
+ *		For most device drivers, no need to care about this flag
+ *		as long as all DMAs are handled through the kernel DMA API.
+ *		For some special ones, for example VFIO drivers, they know
+ *		how to manage the DMA themselves and set this flag so that
+ *		the IOMMU layer will allow them to setup and manage their
+ *		own I/O address space.

+ *                    interrupts are sent until the coalescing
+ *                    timer reaches 0.  When @coalescing_init=0
+ *                    interrupt coalescing is effectively disabled
+ *                    and every interrupt assert results in an

+ * @mask:             Interrupt mask.  When @mask=1 the interrupt
+ *                    resource will not send an interrupt.  When
+ *                    @mask=0 the interrupt resource will send an

+ *                    sent.  When written by software this
+ *                    register atomically decrements @int_credits
+ *                    by the value written.  When @int_credits
+ *                    becomes 0 then the "pending interrupt" bit
+ *                    in the Interrupt Status register is cleared
+ *                    by the hardware and any pending but unsent
+ *                    interrupts are cleared.
+ *                    !!!IMPORTANT!!! This is a signed register.

+ *                       @coal_timer_reset -- When this
+ *                       bit is written with a 1 the
+ *                       @coalescing_curr will be reloaded with
+ *                       @coalescing_init to reset the coalescing
+ *                       timer.
+ * @mask_on_assert:   Automatically mask on assertion.  When
+ *                    @mask_on_assert=1 the interrupt resource
+ *                    will set @mask=1 whenever an interrupt is
+ *                    sent.  When using interrupts in Legacy
+ *                    Interrupt mode the driver must select
+ *                    @mask_on_assert=0 for proper interrupt
+ *                    operation.
+ * @coalescing_curr:  Coalescing timer current value, in

- *
- * The first group is used for accesses that must be done in a

- * 1. Override the function completely. F.e. define this_cpu_add().
- *    The arch must then ensure that the various scalar format passed
- *    are handled correctly.
- *
- * 2. Provide functions for certain scalar sizes. F.e. provide
- *    this_cpu_add_2() to provide per cpu atomic operations for 2 byte
- *    sized RMW actions. If arch code does not provide operations for

+ * "major" change in e.g. interface mode. It will not be called for changes
+ * in speed, duplex or pause modes or to change the in-band advertisement.
+ * In any case, it is strongly preferred that speed, duplex and pause settings
+ * are handled in the mac_link_up() method and not in this method.
+ *
+ * (this requires a rewrite - please refer to mac_link_up() for situations
+ *  where the PCS and MAC are not tightly integrated.)
+ *
+ * In all negotiation modes, as defined by @mode, @state->pause indicates the
+ * pause settings which should be applied as follows. If %MLO_PAUSE_AN is not
+ * set, %MLO_PAUSE_TX and %MLO_PAUSE_RX indicate whether the MAC should send
+ * pause frames and/or act on received pause frames respectively. Otherwise,
+ * the results of in-band negotiation/status from the MAC PCS should be used
+ * to control the MAC pause mode settings.
+ *
+ * The action performed depends on the currently selected mode:
+ *
+ * %MLO_AN_FIXED, %MLO_AN_PHY:
+ *   Configure for non-inband negotiation mode, where the link settings
+ *   are completely communicated via mac_link_up().  The physical link
+ *   protocol from the MAC is specified by @state->interface.
+ *
+ *   @state->advertising may be used, but is not required.
+ *
+ *   Older drivers (prior to the mac_link_up() change) may use @state->speed,
+ *   @state->duplex and @state->pause to configure the MAC, but this is
+ *   deprecated; such drivers should be converted to use mac_link_up().
+ *
+ *   Other members of @state must be ignored.
+ *
+ *   Valid state members: interface, advertising.
+ *   Deprecated state members: speed, duplex, pause.
+ *
+ * %MLO_AN_INBAND:
+ *   place the link in an inband negotiation mode (such as 802.3z
+ *   1000base-X or Cisco SGMII mode depending on the @state->interface
+ *   mode). In both cases, link state management (whether the link
+ *   is up or not) is performed by the MAC, and reported via the
+ *   mac_pcs_get_state() callback. Changes in link state must be made
+ *   by calling phylink_mac_change().
+ *
+ *   Interface mode specific details are mentioned below.
+ *
+ *   If in 802.3z mode, the link speed is fixed, dependent on the
+ *   @state->interface. Duplex and pause modes are negotiated via
+ *   the in-band configuration word. Advertised pause modes are set
+ *   according to the @state->an_enabled and @state->advertising
+ *   flags. Beware of MACs which only support full duplex at gigabit
+ *   and higher speeds.
+ *
+ *   If in Cisco SGMII mode, the link speed and duplex mode are passed
+ *   in the serial bitstream 16-bit configuration word, and the MAC
+ *   should be configured to read these bits and acknowledge the
+ *   configuration word. Nothing is advertised by the MAC. The MAC is
+ *   responsible for reading the configuration word and configuring
+ *   itself accordingly.
+ *
+ *   Valid state members: interface, an_enabled, pause, advertising.
+ *
+ * Implementations are expected to update the MAC to reflect the
+ * requested settings - i.o.w., if nothing has changed between two
+ * calls, no action is expected.  If only flow control settings have
+ * changed, flow control should be updated *without* taking the link
+ * down.  This "update" behaviour is critical to avoid bouncing the

+ * @PIN_CONFIG_SKEW_DELAY: if the pin has programmable skew rate (on inputs)

- *
- * Note: the brcmfmac can be loaded as module or be statically built-in into
- * the kernel. If built-in then do note that it uses module_init (and
- * module_exit) routines which equal device_initcall. So if you intend to
- * create a module with the platform specific data for the brcmfmac and have
- * it built-in to the kernel then use a higher initcall then device_initcall
- * (see init.h). If this is not done then brcmfmac will load without problems
- * but will not pickup the platform data.
- *
- * When the driver does not "detect" platform driver data then it will continue
- * without reporting anything and just assume there is no data needed. Which is
- * probably true for most platforms.
- *
- * Explanation of the platform_data fields:
- *
- * drive_strength: is the preferred drive_strength to be used for the SDIO
- * pins. If 0 then a default value will be used. This is the target drive
- * strength, the exact drive strength which will be used depends on the
- * capabilities of the device.
- *
- * oob_irq_supported: does the board have support for OOB interrupts. SDIO
- * in-band interrupts are relatively slow and for having less overhead on
- * interrupt processing an out of band interrupt can be used. If the HW
- * supports this then enable this by setting this field to true and configure
- * the oob related fields.
- *
- * oob_irq_nr, oob_irq_flags: the OOB interrupt information. The values are
- * used for registering the irq using request_irq function.
- *
- * broken_sg_support: flag for broken sg list support of SDIO host controller.
- * Set this to true if the SDIO host controller has higher align requirement
- * than 32 bytes for each scatterlist item.
- *
- * power_on: This function is called by the brcmfmac when the module gets
- * loaded. This can be particularly useful for low power devices. The platform
- * spcific routine may for example decide to power up the complete device.
- * If there is no use-case for this function then provide NULL.
- *
- * power_off: This function is called by the brcmfmac when the module gets
- * unloaded. At this point the device can be powered down or otherwise be reset.
- * So if an actual power_off is not supported but reset is then reset the device
- * when this function gets called. This can be particularly useful for low power
- * devices. If there is no use-case for this function (either power-down or
- * reset) then provide NULL.
- *
- * reset: This function can get called if the device communication broke down.
- * This functionality is particularly useful in case of SDIO type devices. It is
- * possible to reset a dongle via sdio data interface, but it requires that
- * this is fully functional. This function is chip/module specific and this
- * function should return only after the complete reset has completed.

+ *	Check these conditions, and return 0 if it's appropriate to let the PM
+ *	core queue a suspend request for the device.
+ *
+ * Several device power state transitions are externally visible, affecting
+ * the state of pending I/O queues and (for drivers that touch hardware)
+ * interrupts, wakeups, DMA, and other hardware state.  There may also be
+ * internal transitions to various low-power modes which are transparent
+ * to the rest of the driver stack (such as a driver that's ON gating off
+ * clocks which are not in active use).
+ *
+ * The externally visible transitions are handled with the help of callbacks
+ * included in this structure in such a way that, typically, two levels of
+ * callbacks are involved.  First, the PM core executes callbacks provided by PM
+ * domains, device types, classes and bus types.  They are the subsystem-level
+ * callbacks expected to execute callbacks provided by device drivers, although
+ * they may choose not to do that.  If the driver callbacks are executed, they
+ * have to collaborate with the subsystem-level callbacks to achieve the goals
+ * appropriate for the given system transition, given transition phase and the
+ * subsystem the device belongs to.
  *
- * Refer to Documentation/power/runtime_pm.txt for more information about the
- * role of the above callbacks in device runtime power management.
+ * All of the above callbacks, except for @complete(), return error codes.
+ * However, the error codes returned by @resume(), @thaw(), @restore(),
+ * @resume_noirq(), @thaw_noirq(), and @restore_noirq(), do not cause the PM
+ * core to abort the resume transition during which they are returned.  The
+ * error codes returned in those cases are only printed to the system logs for
+ * debugging purposes.  Still, it is recommended that drivers only return error
+ * codes from their resume methods in case of an unrecoverable failure (i.e.
+ * when the device being handled refuses to resume and becomes unusable) to
+ * allow the PM core to be modified in the future, so that it can avoid
+ * attempting to handle devices that failed to resume and their children.
+ *
+ * It is allowed to unregister devices while the above callbacks are being
+ * executed.  However, a callback routine MUST NOT try to unregister the device
+ * it was called for, although it may unregister children of that device (for
+ * example, if it detects that a child was unplugged while the system was
+ * asleep).
+ *
+ * There also are callbacks related to runtime power management of devices.
+ * Again, as a rule these callbacks are executed by the PM core for subsystems
+ * (PM domains, device types, classes and bus types) and the subsystem-level
+ * callbacks are expected to invoke the driver callbacks.  Moreover, the exact
+ * actions to be performed by a device driver's callbacks generally depend on
+ * the platform and subsystem the device belongs to.
  *
+ * Refer to Documentation/power/runtime_pm.rst for more information about the
+ * role of the @runtime_suspend(), @runtime_resume() and @runtime_idle()
+ * callbacks in device runtime power management.

+ * Flags to control the behaviour of a genpd.
+ *
+ * These flags may be set in the struct generic_pm_domain's flags field by a
+ * genpd backend driver. The flags must be set before it calls pm_genpd_init(),
+ * which initializes a genpd.
+ *
+ * GENPD_FLAG_PM_CLK:		Instructs genpd to use the PM clk framework,
+ *				while powering on/off attached devices.
+ *
+ * GENPD_FLAG_IRQ_SAFE:		This informs genpd that its backend callbacks,
+ *				->power_on|off(), doesn't sleep. Hence, these
+ *				can be invoked from within atomic context, which
+ *				enables genpd to power on/off the PM domain,
+ *				even when pm_runtime_is_irq_safe() returns true,
+ *				for any of its attached devices. Note that, a
+ *				genpd having this flag set, requires its
+ *				masterdomains to also have it set.
+ *
+ * GENPD_FLAG_ALWAYS_ON:	Instructs genpd to always keep the PM domain
+ *				powered on.
+ *
+ * GENPD_FLAG_ACTIVE_WAKEUP:	Instructs genpd to keep the PM domain powered
+ *				on, in case any of its attached devices is used
+ *				in the wakeup path to serve system wakeups.
+ *
+ * GENPD_FLAG_CPU_DOMAIN:	Instructs genpd that it should expect to get
+ *				devices attached, which may belong to CPUs or
+ *				possibly have subdomains with CPUs attached.
+ *				This flag enables the genpd backend driver to
+ *				deploy idle power management support for CPUs
+ *				and groups of CPUs. Note that, the backend
+ *				driver must then comply with the so called,
+ *				last-man-standing algorithm, for the CPUs in the
+ *				PM domain.
+ *
+ * GENPD_FLAG_RPM_ALWAYS_ON:	Instructs genpd to always keep the PM domain
+ *				powered on except for system suspend.
+ *
+ * GENPD_FLAG_MIN_RESIDENCY:	Enable the genpd governor to consider its
+ *				components' next wakeup when determining the
+ *				optimal idle state.

+ *   The corresponding charge_voltage_max_uv is used as a safeguard: when we
+ *   reach this voltage the maintenance charging current is turned off. It is
+ *   turned back on if we fall below this voltage.
+ * @charge_voltage_max_uv: maintenance charging voltage that is usually a bit
+ *   lower than the constant_charge_voltage_max_uv. We can apply this settings
+ *   charge_current_max_ua until we get back up to this voltage.
+ * @safety_timer_minutes: maintenance charging safety timer, with an expiry
+ *   time in minutes. We will only use maintenance charging in this setting
+ *   for a certain amount of time, then we will first move to the next
+ *   maintenance charge current and voltage pair in respective array and wait
+ *   for the next safety timer timeout, or, if we reached the last maintencance
+ *   charging setting, disable charging until we reach
+ *   charge_restart_voltage_uv and restart ordinary CC/CV charging from there.
+ *   These timers should be chosen to align with the typical discharge curve
+ *   for the battery.
+ *
+ * Ordinary CC/CV charging will stop charging when the charge current goes
+ * below charge_term_current_ua, and then restart it (if the device is still
+ * plugged into the charger) at charge_restart_voltage_uv. This happens in most
+ * consumer products because the power usage while connected to a charger is
+ * not zero, and devices are not manufactured to draw power directly from the
+ * charger: instead they will at all times dissipate the battery a little, like
+ * the power used in standby mode. This will over time give a charge graph
+ * such as this:
+ *
+ * Energy
+ *  ^      ...        ...      ...      ...      ...      ...      ...

+ *  +-------------------------------------------------------------------> t
+ *
+ * Practically this means that the Li-ions are wandering back and forth in the
+ * battery and this causes degeneration of the battery anode and cathode.
+ * To prolong the life of the battery, maintenance charging is applied after
+ * reaching charge_term_current_ua to hold up the charge in the battery while
+ * consuming power, thus lowering the wear on the battery:
+ *
+ * Energy
+ *  ^      .......................................

+ *  +-------------------------------------------------------------------> t
+ *
+ * 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

+ *   printed on the label of the battery.
+ * @tricklecharge_current_ua: the tricklecharge current used when trickle
+ *   charging the battery in microamperes. This is the charging phase when the
+ *   battery is completely empty and we need to carefully trickle in some
+ *   charge until we reach the precharging voltage.
+ * @precharge_current_ua: current to use in the precharge phase in microamperes,
+ *   the precharge rate is limited by limiting the current to this value.
+ * @precharge_voltage_max_uv: the maximum voltage allowed when precharging in
+ *   microvolts. When we pass this voltage we will nominally switch over to the
+ *   CC (constant current) charging phase defined by constant_charge_current_ua
+ *   and constant_charge_voltage_max_uv.
+ * @charge_term_current_ua: when the current in the CV (constant voltage)
+ *   charging phase drops below this value in microamperes the charging will
+ *   terminate completely and not restart until the voltage over the battery
+ *   poles reach charge_restart_voltage_uv unless we use maintenance charging.
+ * @charge_restart_voltage_uv: when the battery has been fully charged by
+ *   CC/CV charging and charging has been disabled, and the voltage subsequently
+ *   drops below this value in microvolts, the charging will be restarted
+ *   (typically using CV charging).
+ * @overvoltage_limit_uv: If the voltage exceeds the nominal voltage
+ *   voltage_max_design_uv and we reach this voltage level, all charging must
+ *   stop and emergency procedures take place, such as shutting down the system
+ *   in some cases.
+ * @constant_charge_current_max_ua: current in microamperes to use in the CC
+ *   (constant current) charging phase. The charging rate is limited
+ *   by this current. This is the main charging phase and as the current is
+ *   constant into the battery the voltage slowly ascends to
+ *   constant_charge_voltage_max_uv.
+ * @constant_charge_voltage_max_uv: voltage in microvolts signifying the end of
+ *   the CC (constant current) charging phase and the beginning of the CV
+ *   (constant voltage) charging phase.
+ * @maintenance_charge: an array of maintenance charging settings to be used
+ *   after the main CC/CV charging phase is complete.
+ * @maintenance_charge_size: the number of maintenance charging settings in
+ *   maintenance_charge.
+ * @alert_low_temp_charge_current_ua: The charging current to use if the battery
+ *   enters low alert temperature, i.e. if the internal temperature is between
+ *   temp_alert_min and temp_min. No matter the charging phase, this
+ *   and alert_high_temp_charge_voltage_uv will be applied.
+ * @alert_low_temp_charge_voltage_uv: Same as alert_low_temp_charge_current_ua,
+ *   but for the charging voltage.
+ * @alert_high_temp_charge_current_ua: The charging current to use if the
+ *   battery enters high alert temperature, i.e. if the internal temperature is
+ *   between temp_alert_max and temp_max. No matter the charging phase, this
+ *   and alert_high_temp_charge_voltage_uv will be applied, usually lowering
+ *   the charging current as an evasive manouver.
+ * @alert_high_temp_charge_voltage_uv: Same as
+ *   alert_high_temp_charge_current_ua, but for the charging voltage.
+ * @factory_internal_resistance_uohm: the internal resistance of the battery
+ *   at fabrication time, expressed in microohms. This resistance will vary
+ *   depending on the lifetime and charge of the battery, so this is just a
+ *   nominal ballpark figure. This internal resistance is given for the state
+ *   when the battery is discharging.
+ * @factory_internal_resistance_charging_uohm: the internal resistance of the
+ *   battery at fabrication time while charging, expressed in microohms.
+ *   The charging process will affect the internal resistance of the battery
+ *   so this value provides a better resistance under these circumstances.
+ *   This resistance will vary depending on the lifetime and charge of the
+ *   battery, so this is just a nominal ballpark figure.
+ * @ocv_temp: array indicating the open circuit voltage (OCV) capacity
+ *   temperature indices. This is an array of temperatures in degrees Celsius
+ *   indicating which capacity table to use for a certain temperature, since
+ *   the capacity for reasons of chemistry will be different at different
+ *   temperatures. Determining capacity is a multivariate problem and the
+ *   temperature is the first variable we determine.
+ * @temp_ambient_alert_min: the battery will go outside of operating conditions
+ *   when the ambient temperature goes below this temperature in degrees
+ *   Celsius.
+ * @temp_ambient_alert_max: the battery will go outside of operating conditions
+ *   when the ambient temperature goes above this temperature in degrees
+ *   Celsius.
+ * @temp_alert_min: the battery should issue an alert if the internal
+ *   temperature goes below this temperature in degrees Celsius.
+ * @temp_alert_max: the battery should issue an alert if the internal
+ *   temperature goes above this temperature in degrees Celsius.
+ * @temp_min: the battery will go outside of operating conditions when
+ *   the internal temperature goes below this temperature in degrees Celsius.
+ *   Normally this means the system should shut down.
+ * @temp_max: the battery will go outside of operating conditions when
+ *   the internal temperature goes above this temperature in degrees Celsius.
+ *   Normally this means the system should shut down.
+ * @ocv_table: for each entry in ocv_temp there is a corresponding entry in

+ *   determine the capacity in percent in relation to the voltage in microvolts
+ *   at the indexed temperature.
+ * @ocv_table_size: for each entry in ocv_temp this array is giving the size of
+ *   each entry in the array of capacity arrays in ocv_table.
+ * @resist_table: this is a table that correlates a battery temperature to the
+ *   expected internal resistance at this temperature. The resistance is given
+ *   as a percentage of factory_internal_resistance_uohm. Knowing the
+ *   resistance of the battery is usually necessary for calculating the open
+ *   circuit voltage (OCV) that is then used with the ocv_table to calculate
+ *   the capacity of the battery. The resist_table must be ordered descending
+ *   by temperature: highest temperature with lowest resistance first, lowest
+ *   temperature with highest resistance last.
+ * @resist_table_size: the number of items in the resist_table.
+ * @vbat2ri_discharging: this is a table that correlates Battery voltage (VBAT)
+ *   to internal resistance (Ri). The resistance is given in microohm for the
+ *   corresponding voltage in microvolts. The internal resistance is used to
+ *   determine the open circuit voltage so that we can determine the capacity
+ *   of the battery. These voltages to resistance tables apply when the battery
+ *   is discharging. The table must be ordered descending by voltage: highest
+ *   voltage first.
+ * @vbat2ri_discharging_size: the number of items in the vbat2ri_discharging
+ *   table.
+ * @vbat2ri_charging: same function as vbat2ri_discharging but for the state
+ *   when the battery is charging. Being under charge changes the battery's
+ *   internal resistance characteristics so a separate table is needed.*
+ *   The table must be ordered descending by voltage: highest voltage first.
+ * @vbat2ri_charging_size: the number of items in the vbat2ri_charging
+ *   table.
+ * @bti_resistance_ohm: The Battery Type Indicator (BIT) nominal resistance
+ *   in ohms for this battery, if an identification resistor is mounted
+ *   between a third battery terminal and ground. This scheme is used by a lot
+ *   of mobile device batteries.
+ * @bti_resistance_tolerance: The tolerance in percent of the BTI resistance,
+ *   for example 10 for +/- 10%, if the bti_resistance is set to 7000 and the
+ *   tolerance is 10% we will detect a proper battery if the BTI resistance
+ *   is between 6300 and 7700 Ohm.
+ *
+ * This is the recommended struct to manage static battery parameters,
+ * populated by power_supply_get_battery_info(). Most platform drivers should
+ * use these for consistency.
+ *
+ * Its field names must correspond to elements in enum power_supply_property.
+ * The default field value is -EINVAL or NULL for pointers.
+ *
+ * CC/CV CHARGING:
+ *
+ * The charging parameters here assume a CC/CV charging scheme. This method
+ * is most common with Lithium Ion batteries (other methods are possible) and
+ * looks as follows:
+ *
+ * ^ Battery voltage
+ * |                                               --- overvoltage_limit_uv
+ * |
+ * |                    ...................................................
+ * |                 .. constant_charge_voltage_max_uv
+ * |              ..
+ * |             .
+ * |            .
+ * |           .
+ * |          .
+ * |         .
+ * |     .. precharge_voltage_max_uv
+ * |  ..
+ * |. (trickle charging)
+ * +------------------------------------------------------------------> time
+ *
+ * ^ Current into the battery
+ * |
+ * |      ............. constant_charge_current_max_ua
+ * |      .            .
+ * |      .             .
+ * |      .              .
+ * |      .               .
+ * |      .                ..
+ * |      .                  ....
+ * |      .                       .....
+ * |    ... precharge_current_ua       .......  charge_term_current_ua
+ * |    .                                    .
+ * |    .                                    .
+ * |.... tricklecharge_current_ua            .
+ * |                                         .
+ * +-----------------------------------------------------------------> time
+ *
+ * These diagrams are synchronized on time and the voltage and current
+ * follow each other.
+ *
+ * With CC/CV charging commence over time like this for an empty battery:
+ *
+ * 1. When the battery is completely empty it may need to be charged with
+ *    an especially small current so that electrons just "trickle in",
+ *    this is the tricklecharge_current_ua.
+ *
+ * 2. Next a small initial pre-charge current (precharge_current_ua)
+ *    is applied if the voltage is below precharge_voltage_max_uv until we
+ *    reach precharge_voltage_max_uv. CAUTION: in some texts this is referred
+ *    to as "trickle charging" but the use in the Linux kernel is different
+ *    see below!
+ *
+ * 3. Then the main charging current is applied, which is called the constant
+ *    current (CC) phase. A current regulator is set up to allow
+ *    constant_charge_current_max_ua of current to flow into the battery.
+ *    The chemical reaction in the battery will make the voltage go up as
+ *    charge goes into the battery. This current is applied until we reach
+ *    the constant_charge_voltage_max_uv voltage.
+ *
+ * 4. At this voltage we switch over to the constant voltage (CV) phase. This
+ *    means we allow current to go into the battery, but we keep the voltage
+ *    fixed. This current will continue to charge the battery while keeping
+ *    the voltage the same. A chemical reaction in the battery goes on
+ *    storing energy without affecting the voltage. Over time the current
+ *    will slowly drop and when we reach charge_term_current_ua we will
+ *    end the constant voltage phase.
+ *
+ * After this the battery is fully charged, and if we do not support maintenance
+ * charging, the charging will not restart until power dissipation makes the
+ * voltage fall so that we reach charge_restart_voltage_uv and at this point
+ * we restart charging at the appropriate phase, usually this will be inside
+ * the CV phase.
+ *
+ * If we support maintenance charging the voltage is however kept high after
+ * the CV phase with a very low current. This is meant to let the same charge
+ * go in for usage while the charger is still connected, mainly for
+ * dissipation for the power consuming entity while connected to the
+ * charger.
+ *
+ * All charging MUST terminate if the overvoltage_limit_uv is ever reached.
+ * Overcharging Lithium Ion cells can be DANGEROUS and lead to fire or
+ * explosions.
+ *
+ * DETERMINING BATTERY CAPACITY:
+ *
+ * Several members of the struct deal with trying to determine the remaining
+ * capacity in the battery, usually as a percentage of charge. In practice
+ * 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.

+ * Migrate-Disable and why it is undesired.
+ *
+ * When a preempted task becomes elegible to run under the ideal model (IOW it
+ * becomes one of the M highest priority tasks), it might still have to wait
+ * for the preemptee's migrate_disable() section to complete. Thereby suffering
+ * a reduction in bandwidth in the exact duration of the migrate_disable()
+ * section.
+ *
+ * Per this argument, the change from preempt_disable() to migrate_disable()
+ * gets us:
+ *
+ * - a higher priority tasks gains reduced wake-up latency; with preempt_disable()
+ *   it would have had to wait for the lower priority task.
+ *
+ * - a lower priority tasks; which under preempt_disable() could've instantly
+ *   migrated away when another CPU becomes available, is now constrained
+ *   by the ability to push the higher priority task away, which might itself be
+ *   in a migrate_disable() section, reducing it's available bandwidth.
+ *
+ * IOW it trades latency / moves the interference term, but it stays in the
+ * system, and as long as it remains unbounded, the system is not fully
+ * deterministic.
+ *
+ *
+ * The reason we have it anyway.
+ *
+ * PREEMPT_RT breaks a number of assumptions traditionally held. By forcing a
+ * number of primitives into becoming preemptible, they would also allow
+ * migration. This turns out to break a bunch of per-cpu usage. To this end,
+ * all these primitives employ migirate_disable() to restore this implicit
+ * assumption.
+ *
+ * This is a 'temporary' work-around at best. The correct solution is getting
+ * rid of the above assumptions and reworking the code to employ explicit
+ * per-cpu locking or short preempt-disable regions.
+ *
+ * The end goal must be to get rid of migrate_disable(), alternatively we need
+ * a schedulability theory that does not depend on abritrary migration.
+ *
+ *
+ * Notes on the implementation.
+ *
+ * The implementation is particularly tricky since existing code patterns
+ * dictate neither migrate_disable() nor migrate_enable() is allowed to block.
+ * This means that it cannot use cpus_read_lock() to serialize against hotplug,
+ * nor can it easily migrate itself into a pending affinity mask change on
+ * migrate_enable().
+ *
+ *
+ * Note: even non-work-conserving schedulers like semi-partitioned depends on
+ *       migration, so migrate_disable() is not only a problem for
+ *       work-conserving schedulers.

+ * @data:	backend-private pointer passed back during callbacks

+ * Callbacks:
+ *
+ * @open:
+ *	Notify backend that pstore is starting a full read of backend
+ *	records. Followed by one or more @read calls, and a final @close.
+ *
+ *	@psi:	in: pointer to the struct pstore_info for the backend
+ *
+ *	Returns 0 on success, and non-zero on error.
+ *
+ * @close:
+ *	Notify backend that pstore has finished a full read of backend
+ *	records. Always preceded by an @open call and one or more @read
+ *	calls.
+ *
+ *	@psi:	in: pointer to the struct pstore_info for the backend
+ *
+ *	Returns 0 on success, and non-zero on error. (Though pstore will
+ *	ignore the error.)
+ *
+ * @read:
+ *	Read next available backend record. Called after a successful
+ *	@open.
+ *
+ *	@record:
+ *		pointer to record to populate. @buf should be allocated
+ *		by the backend and filled. At least @type and @id should
+ *		be populated, since these are used when creating pstorefs
+ *		file names.
+ *
+ *	Returns record size on success, zero when no more records are
+ *	available, or negative on error.
+ *
+ * @write:
+ *	A newly generated record needs to be written to backend storage.
+ *
+ *	@record:
+ *		pointer to record metadata. When @type is PSTORE_TYPE_DMESG,
+ *		@buf will be pointing to the preallocated @psi.buf, since
+ *		memory allocation may be broken during an Oops. Regardless,
+ *		@buf must be proccesed or copied before returning. The
+ *		backend is also expected to write @id with something that
+ *		can help identify this record to a future @erase callback.
+ *		The @time field will be prepopulated with the current time,
+ *		when available. The @size field will have the size of data
+ *		in @buf.
+ *
+ *	Returns 0 on success, and non-zero on error.
+ *
+ * @write_user:
+ *	Perform a frontend write to a backend record, using a specified
+ *	buffer that is coming directly from userspace, instead of the
+ *	@record @buf.
+ *
+ *	@record:	pointer to record metadata.
+ *	@buf:		pointer to userspace contents to write to backend
+ *
+ *	Returns 0 on success, and non-zero on error.
+ *
+ * @erase:
+ *	Delete a record from backend storage.  Different backends
+ *	identify records differently, so entire original record is
+ *	passed back to assist in identification of what the backend
+ *	should remove from storage.
+ *
+ *	@record:	pointer to record metadata.
+ *
+ *	Returns 0 on success, and non-zero on error.

+ *            Hardware Clock subsystem maintains the 'pin_config'
+ *            array on behalf of the drivers, but the PHC subsystem

+ * Since RB-trees have non-atomic modifications they're not immediately suited
+ * for RCU/lockless queries. Even though we made RB-tree lookups non-fatal for
+ * lockless lookups; we cannot guarantee they return a correct result.
+ *
+ * The simplest solution is a seqlock + RB-tree, this will allow lockless
+ * lookups; but has the constraint (inherent to the seqlock) that read sides
+ * cannot nest in write sides.
+ *
+ * If we need to allow unconditional lookups (say as required for NMI context
+ * usage) we need a more complex setup; this data structure provides this by
+ * employing the latch technique -- see @raw_write_seqcount_latch -- to
+ * implement a latched RB-tree which does allow for unconditional lookups by
+ * virtue of always having (at least) one stable copy of the tree.
+ *
+ * However, while we have the guarantee that there is at all times one stable
+ * copy, this does not guarantee an iteration will not observe modifications.
+ * What might have been a stable copy at the start of the iteration, need not
+ * remain so for the duration of the iteration.
+ *
+ * Therefore, this does require a lockless RB-tree iteration to be non-fatal;
+ * see the comment in lib/rbtree.c. Note however that we only require the first
+ * condition -- not seeing partial stores -- because the latch thing isolates
+ * us from loops. If we were to interrupt a modification the lookup would be
+ * pointed at the stable tree and complete while the modification was halted.

- * call_rcu() - Queue an RCU callback for invocation after a grace period.
- * @head: structure to be used for queueing the RCU updates.
- * @func: actual callback function to be invoked after the grace period
- *
- * The callback function will be invoked some time after a full grace
- * period elapses, in other words after all pre-existing RCU read-side
- * critical sections have completed.  However, the callback function
- * might well execute concurrently with RCU read-side critical sections
- * that started after call_rcu() was invoked.  RCU read-side critical
- * sections are delimited by rcu_read_lock() and rcu_read_unlock(),
- * and may be nested.
- *
- * Note that all CPUs must agree that the grace period extended beyond
- * all pre-existing RCU read-side critical section.  On systems with more
- * than one CPU, this means that when "func()" is invoked, each CPU is
- * guaranteed to have executed a full memory barrier since the end of its
- * last RCU read-side critical section whose beginning preceded the call
- * to call_rcu().  It also means that each CPU executing an RCU read-side
- * critical section that continues beyond the start of "func()" must have

  *
- * Wait for an RCU-bh grace period to elapse, but use a "big hammer"
- * approach to force the grace period to end quickly.  This consumes
- * significant time on all CPUs and is unfriendly to real-time workloads,
- * so is thus not recommended for any sort of common-case code.  In fact,
- * if you are using synchronize_rcu_bh_expedited() in a loop, please
- * restructure your code to batch your updates, and then use a single
- * synchronize_rcu_bh() instead.
+ * The two old-state values must have been obtained from either
+ * get_state_synchronize_rcu_full(), start_poll_synchronize_rcu_full(),
+ * or get_completed_synchronize_rcu_full().  Returns @true if the two
+ * values are identical and @false otherwise.  This allows structures
+ * whose lifetimes are tracked by old-state values to push these values
+ * to a list header, allowing those structures to be slightly smaller.
  *
- * Note that it is illegal to call this function while holding any lock
- * that is acquired by a CPU-hotplug notifier.  And yes, it is also illegal
- * to call this function from a CPU-hotplug notifier.  Failing to observe
- * these restriction will result in deadlock.
+ * Note that equality is judged on a bitwise basis, so that an
+ * @rcu_gp_oldstate structure with an already-completed state in one field
+ * will compare not-equal to a structure with an already-completed state
+ * in the other field.  After all, the @rcu_gp_oldstate structure is opaque

  *
- * This optimizes the (A/B) problem, when A and B are two u32
- * and B is a known value (but not known at compile time)
+ * The assembler implementation from Agner Fog, which this code is
+ * based on, can be found here:
+ * http://www.agner.org/optimize/asmlib.zip
  *
- * The math principle used is :
- *   Let RECIPROCAL_VALUE(B) be (((1LL << 32) + (B - 1))/ B)
- *   Then A / B = (u32)(((u64)(A) * (R)) >> 32)
- *
- * This replaces a divide by a multiply (and a shift), and
- * is generally less expensive in CPU cycles.
+ * This optimization for A/B is helpful if the divisor B is mostly
+ * runtime invariant. The reciprocal of B is calculated in the
+ * slow-path with reciprocal_value(). The fast-path can then just use
+ * a much faster multiplication operation with a variable dividend A
+ * to calculate the division A/B.

+ * Variant of atomic_t specialized for reference counts.
+ *
+ * The interface matches the atomic_t interface (to aid in porting) but only
+ * provides the few functions one should use for reference counting.
+ *
+ * Saturation semantics
+ * ====================
+ *
+ * refcount_t differs from atomic_t in that the counter saturates at
+ * REFCOUNT_SATURATED and will not move once there. This avoids wrapping the
+ * counter and causing 'spurious' use-after-free issues. In order to avoid the
+ * cost associated with introducing cmpxchg() loops into all of the saturating
+ * operations, we temporarily allow the counter to take on an unchecked value
+ * and then explicitly set it to REFCOUNT_SATURATED on detecting that underflow
+ * or overflow has occurred. Although this is racy when multiple threads
+ * access the refcount concurrently, by placing REFCOUNT_SATURATED roughly
+ * equidistant from 0 and INT_MAX we minimise the scope for error:
+ *
+ * 	                           INT_MAX     REFCOUNT_SATURATED   UINT_MAX
+ *   0                          (0x7fff_ffff)    (0xc000_0000)    (0xffff_ffff)
+ *   +--------------------------------+----------------+----------------+
+ *                                     <---------- bad value! ---------->
+ *
+ * (in a signed view of the world, the "bad value" range corresponds to
+ * a negative counter value).
+ *
+ * As an example, consider a refcount_inc() operation that causes the counter
+ * to overflow:
+ *
+ * 	int old = atomic_fetch_add_relaxed(r);
+ *	// old is INT_MAX, refcount now INT_MIN (0x8000_0000)
+ *	if (old < 0)
+ *		atomic_set(r, REFCOUNT_SATURATED);
+ *
+ * If another thread also performs a refcount_inc() operation between the two
+ * atomic operations, then the count will continue to edge closer to 0. If it
+ * reaches a value of 1 before /any/ of the threads reset it to the saturated
+ * value, then a concurrent refcount_dec_and_test() may erroneously free the
+ * underlying object.
+ * Linux limits the maximum number of tasks to PID_MAX_LIMIT, which is currently
+ * 0x400000 (and can't easily be raised in the future beyond FUTEX_TID_MASK).
+ * With the current PID limit, if no batched refcounting operations are used and
+ * the attacker can't repeatedly trigger kernel oopses in the middle of refcount
+ * operations, this makes it impossible for a saturated refcount to leave the
+ * saturation range, even if it is possible for multiple uses of the same
+ * refcount to nest in the context of a single task:
+ *
+ *     (UINT_MAX+1-REFCOUNT_SATURATED) / PID_MAX_LIMIT =
+ *     0x40000000 / 0x400000 = 0x100 = 256
+ *
+ * If hundreds of references are added/removed with a single refcounting
+ * operation, it may potentially be possible to leave the saturation range; but
+ * given the precise timing details involved with the round-robin scheduling of
+ * each thread manipulating the refcount and the need to hit the race multiple
+ * times in succession, there doesn't appear to be a practical avenue of attack
+ * even if using refcount_add() operations with larger increments.
+ *
+ * Memory ordering
+ * ===============
+ *
+ * Memory ordering rules are slightly relaxed wrt regular atomic_t functions
+ * and provide only what is strictly required for refcounts.
+ *
+ * The increments are fully relaxed; these will not provide ordering. The
+ * rationale is that whatever is used to obtain the object we're increasing the
+ * reference count on will provide the ordering. For locked data structures,
+ * its the lock acquire, for RCU/lockless data structures its the dependent
+ * load.
+ *
+ * Do note that inc_not_zero() provides a control dependency which will order
+ * future stores against the inc, this ensures we'll never modify the object
+ * if we did not in fact acquire a reference.
+ *
+ * The decrements will provide release order, such that all the prior loads and
+ * stores will be issued before, it also provides a control dependency, which
+ * will order us against the subsequent free().
+ *
+ * The control dependency is against the load of the cmpxchg (ll/sc) that
+ * succeeded. This means the stores aren't fully ordered, but this is fine
+ * because the 1->0 transition indicates no concurrency.
+ *
+ * Note that the allocator is responsible for ordering things between free()
+ * and alloc().
+ *
+ * The decrements dec_and_test() and sub_and_test() also provide acquire
+ * ordering on success.

+ * struct regmap_irq_chip - Description of a generic regmap irq_chip.
  *
  * @name:        Descriptive name for IRQ controller.
  *
+ * @main_status: Base main status register address. For chips which have
+ *		 interrupts arranged in separate sub-irq blocks with own IRQ
+ *		 registers and which have a main IRQ registers indicating
+ *		 sub-irq blocks with unhandled interrupts. For such chips fill
+ *		 sub-irq register information in status_base, mask_base and
+ *		 ack_base.
+ * @num_main_status_bits: Should be given to chips where number of meaningfull
+ *			  main status bits differs from num_regs.
+ * @sub_reg_offsets: arrays of mappings from main register bits to sub irq
+ *		     registers. First item in array describes the registers
+ *		     for first main status bit. Second array for second bit etc.
+ *		     Offset is given as sub register status offset to
+ *		     status_base. Should contain num_regs arrays.
+ *		     Can be provided for chips with more complex mapping than
+ *		     1.st bit to 1.st sub-reg, 2.nd bit to 2.nd sub-reg, ...
+ *		     When used with not_fixed_stride, each one-element array
+ *		     member contains offset calculated as address from each
+ *		     peripheral to first peripheral.
+ * @num_main_regs: Number of 'main status' irq registers for chips which have
+ *		   main_status set.
+ *
  * @status_base: Base status register address.
- * @mask_base:   Base mask register address.
- * @ack_base:    Base ack address.  If zero then the chip is clear on read.
+ * @mask_base:   Base mask register address. Mask bits are set to 1 when an
+ *               interrupt is masked, 0 when unmasked.
+ * @unmask_base:  Base unmask register address. Unmask bits are set to 1 when
+ *                an interrupt is unmasked and 0 when masked.
+ * @ack_base:    Base ack address. If zero then the chip is clear on read.
+ *               Using zero value is possible with @use_ack bit.
  * @wake_base:   Base address for wake enables.  If zero unsupported.
+ * @type_base:   Base address for irq type.  If zero unsupported.  Deprecated,
+ *		 use @config_base instead.
+ * @virt_reg_base:   Base addresses for extra config regs. Deprecated, use
+ *		     @config_base instead.
+ * @config_base: Base address for IRQ type config regs. If null unsupported.
  * @irq_reg_stride:  Stride to use for chips where registers are not contiguous.
+ * @init_ack_masked: Ack all masked interrupts once during initalization.
+ * @mask_unmask_non_inverted: Controls mask bit inversion for chips that set
+ *	both @mask_base and @unmask_base. If false, mask and unmask bits are
+ *	inverted (which is deprecated behavior); if true, bits will not be
+ *	inverted and the registers keep their normal behavior. Note that if
+ *	you use only one of @mask_base or @unmask_base, this flag has no
+ *	effect and is unnecessary. Any new drivers that set both @mask_base
+ *	and @unmask_base should set this to true to avoid relying on the
+ *	deprecated behavior.
+ * @use_ack:     Use @ack register even if it is zero.
+ * @ack_invert:  Inverted ack register: cleared bits for ack.
+ * @clear_ack:  Use this to set 1 and 0 or vice-versa to clear interrupts.
+ * @status_invert: Inverted status register: cleared bits are active interrupts.
+ * @wake_invert: Inverted wake register: cleared bits are wake enabled.
+ * @type_in_mask: Use the mask registers for controlling irq type. Use this if
+ *		  the hardware provides separate bits for rising/falling edge
+ *		  or low/high level interrupts and they should be combined into
+ *		  a single logical interrupt. Use &struct regmap_irq_type data
+ *		  to define the mask bit for each irq type.
+ * @clear_on_unmask: For chips with interrupts cleared on read: read the status
+ *                   registers before unmasking interrupts to clear any bits
+ *                   set when they were masked.
  * @runtime_pm:  Hold a runtime PM lock on the device when accessing it.
+ * @not_fixed_stride: Used when chip peripherals are not laid out with fixed
+ *		      stride. Must be used with sub_reg_offsets containing the
+ *		      offsets to each peripheral. Deprecated; the same thing
+ *		      can be accomplished with a @get_irq_reg callback, without
+ *		      the need for a @sub_reg_offsets table.
+ * @no_status: No status register: all interrupts assumed generated by device.
  *
  * @num_regs:    Number of registers in each control bank.
+ *
  * @irqs:        Descriptors for individual IRQs.  Interrupt numbers are
  *               assigned based on the index in the array of the interrupt.
  * @num_irqs:    Number of descriptors.
+ *
+ * @num_type_reg:    Number of type registers. Deprecated, use config registers
+ *		     instead.
+ * @num_virt_regs:   Number of non-standard irq configuration registers.
+ *		     If zero unsupported. Deprecated, use config registers
+ *		     instead.
+ * @num_config_bases:	Number of config base registers.
+ * @num_config_regs:	Number of config registers for each config base register.
+ *
+ * @handle_pre_irq:  Driver specific callback to handle interrupt from device
+ *		     before regmap_irq_handler process the interrupts.
+ * @handle_post_irq: Driver specific callback to handle interrupt from device
+ *		     after handling the interrupts in regmap_irq_handler().
+ * @handle_mask_sync: Callback used to handle IRQ mask syncs. The index will be
+ *		      in the range [0, num_regs)
+ * @set_type_virt:   Driver specific callback to extend regmap_irq_set_type()
+ *		     and configure virt regs. Deprecated, use @set_type_config
+ *		     callback and config registers instead.
+ * @set_type_config: Callback used for configuring irq types.
+ * @get_irq_reg: Callback for mapping (base register, index) pairs to register
+ *		 addresses. The base register will be one of @status_base,
+ *		 @mask_base, etc., @main_status, or any of @config_base.
+ *		 The index will be in the range [0, num_main_regs[ for the
+ *		 main status base, [0, num_type_settings[ for any config
+ *		 register base, and [0, num_regs[ for any other base.
+ *		 If unspecified then regmap_irq_get_irq_reg_linear() is used.

+ * The load/runnable/util_avg accumulates an infinite geometric series
+ * (see __update_load_avg_cfs_rq() in kernel/sched/pelt.c).
+ *
+ * [load_avg definition]
+ *
+ *   load_avg = runnable% * scale_load_down(load)
+ *
+ * [runnable_avg definition]
+ *
+ *   runnable_avg = runnable% * SCHED_CAPACITY_SCALE
+ *
+ * [util_avg definition]
+ *
+ *   util_avg = running% * SCHED_CAPACITY_SCALE
+ *
+ * where runnable% is the time ratio that a sched_entity is runnable and
+ * running% the time ratio that a sched_entity is running.
+ *
+ * For cfs_rq, they are the aggregated values of all runnable and blocked
+ * sched_entities.
+ *
+ * The load/runnable/util_avg doesn't directly factor frequency scaling and CPU
+ * capacity scaling. The scaling is done through the rq_clock_pelt that is used
+ * for computing those signals (see update_rq_clock_pelt())
+ *
+ * N.B., the above ratios (runnable% and running%) themselves are in the
+ * range of [0, 1]. To do fixed point arithmetics, we therefore scale them
+ * to as large a range as necessary. This is for example reflected by
+ * util_avg's SCHED_CAPACITY_SCALE.
+ *
+ * [Overflow issue]
+ *
+ * The 64-bit load_sum can have 4353082796 (=2^64/47742/88761) entities
+ * with the highest load (=88761), always runnable on a single cfs_rq,
+ * and should not overflow as the number already hits PID_MAX_LIMIT.
+ *
+ * For all other cases (including 32-bit kernels), struct load_weight's
+ * weight will overflow first before we do, because:
+ *
+ *    Max(load_avg) <= Max(load.weight)
+ *
+ * Then it is the load_weight's responsibility to consider overflow
+ * issues.

- * struct security_operations - main security structure
- *
- * Security module identifier.
- *
- * @name:
- *	A string that acts as a unique identifier for the LSM with max number
- *	of characters = SECURITY_NAME_MAX.
- *
- * Security hooks for program execution operations.
- *
- * @bprm_set_creds:
- *	Save security information in the bprm->security field, typically based
- *	on information about the bprm->file, for later use by the apply_creds
- *	hook.  This hook may also optionally check permissions (e.g. for
- *	transitions between security domains).
- *	This hook may be called multiple times during a single execve, e.g. for
- *	interpreters.  The hook can tell whether it has already been called by
- *	checking to see if @bprm->security is non-NULL.  If so, then the hook
- *	may decide either to retain the security information saved earlier or
- *	to replace it.
- *	@bprm contains the linux_binprm structure.
- *	Return 0 if the hook is successful and permission is granted.
- * @bprm_check_security:
- *	This hook mediates the point when a search for a binary handler will
- *	begin.  It allows a check the @bprm->security value which is set in the
- *	preceding set_creds call.  The primary difference from set_creds is
- *	that the argv list and envp list are reliably available in @bprm.  This
- *	hook may be called multiple times during a single execve; and in each
- *	pass set_creds is called first.
- *	@bprm contains the linux_binprm structure.
- *	Return 0 if the hook is successful and permission is granted.
- * @bprm_committing_creds:
- *	Prepare to install the new security attributes of a process being
- *	transformed by an execve operation, based on the old credentials
- *	pointed to by @current->cred and the information set in @bprm->cred by
- *	the bprm_set_creds hook.  @bprm points to the linux_binprm structure.
- *	This hook is a good place to perform state changes on the process such
- *	as closing open file descriptors to which access will no longer be
- *	granted when the attributes are changed.  This is called immediately
- *	before commit_creds().
- * @bprm_committed_creds:
- *	Tidy up after the installation of the new security attributes of a
- *	process being transformed by an execve operation.  The new credentials
- *	have, by this point, been set to @current->cred.  @bprm points to the
- *	linux_binprm structure.  This hook is a good place to perform state
- *	changes on the process such as clearing out non-inheritable signal
- *	state.  This is called immediately after commit_creds().
- * @bprm_secureexec:
- *	Return a boolean value (0 or 1) indicating whether a "secure exec"
- *	is required.  The flag is passed in the auxiliary table
- *	on the initial stack to the ELF interpreter to indicate whether libc
- *	should enable secure mode.
- *	@bprm contains the linux_binprm structure.
- *
- * Security hooks for filesystem operations.
- *
- * @sb_alloc_security:
- *	Allocate and attach a security structure to the sb->s_security field.
- *	The s_security field is initialized to NULL when the structure is
- *	allocated.
- *	@sb contains the super_block structure to be modified.
- *	Return 0 if operation was successful.
- * @sb_free_security:
- *	Deallocate and clear the sb->s_security field.
- *	@sb contains the super_block structure to be modified.
- * @sb_statfs:
- *	Check permission before obtaining filesystem statistics for the @mnt
- *	mountpoint.
- *	@dentry is a handle on the superblock for the filesystem.
- *	Return 0 if permission is granted.
- * @sb_mount:
- *	Check permission before an object specified by @dev_name is mounted on
- *	the mount point named by @nd.  For an ordinary mount, @dev_name
- *	identifies a device if the file system type requires a device.  For a
- *	remount (@flags & MS_REMOUNT), @dev_name is irrelevant.  For a
- *	loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
- *	pathname of the object being mounted.
- *	@dev_name contains the name for object being mounted.
- *	@path contains the path for mount point object.
- *	@type contains the filesystem type.
- *	@flags contains the mount flags.
- *	@data contains the filesystem-specific data.
- *	Return 0 if permission is granted.
- * @sb_copy_data:
- *	Allow mount option data to be copied prior to parsing by the filesystem,
- *	so that the security module can extract security-specific mount
- *	options cleanly (a filesystem may modify the data e.g. with strsep()).
- *	This also allows the original mount data to be stripped of security-
- *	specific options to avoid having to make filesystems aware of them.
- *	@type the type of filesystem being mounted.
- *	@orig the original mount data copied from userspace.
- *	@copy copied data which will be passed to the security module.
- *	Returns 0 if the copy was successful.
- * @sb_remount:
- *	Extracts security system specific mount options and verifies no changes
- *	are being made to those options.
- *	@sb superblock being remounted
- *	@data contains the filesystem-specific data.
- *	Return 0 if permission is granted.
- * @sb_umount:
- *	Check permission before the @mnt file system is unmounted.
- *	@mnt contains the mounted file system.
- *	@flags contains the unmount flags, e.g. MNT_FORCE.
- *	Return 0 if permission is granted.
- * @sb_pivotroot:
- *	Check permission before pivoting the root filesystem.
- *	@old_path contains the path for the new location of the current root (put_old).
- *	@new_path contains the path for the new root (new_root).
- *	Return 0 if permission is granted.
- * @sb_set_mnt_opts:
- *	Set the security relevant mount options used for a superblock
- *	@sb the superblock to set security mount options for
- *	@opts binary data structure containing all lsm mount data
- * @sb_clone_mnt_opts:
- *	Copy all security options from a given superblock to another
- *	@oldsb old superblock which contain information to clone
- *	@newsb new superblock which needs filled in
- * @sb_parse_opts_str:
- *	Parse a string of security data filling in the opts structure
- *	@options string containing all mount options known by the LSM
- *	@opts binary data structure usable by the LSM
- * @dentry_init_security:
- *	Compute a context for a dentry as the inode is not yet available
- *	since NFSv4 has no label backed by an EA anyway.
- *	@dentry dentry to use in calculating the context.
- *	@mode mode used to determine resource type.
- *	@name name of the last path component used to create file
- *	@ctx pointer to place the pointer to the resulting context in.
- *	@ctxlen point to place the length of the resulting context.
- *
- *
- * Security hooks for inode operations.
- *
- * @inode_alloc_security:
- *	Allocate and attach a security structure to @inode->i_security.  The
- *	i_security field is initialized to NULL when the inode structure is
- *	allocated.
- *	@inode contains the inode structure.
- *	Return 0 if operation was successful.
- * @inode_free_security:
- *	@inode contains the inode structure.
- *	Deallocate the inode security structure and set @inode->i_security to
- *	NULL.
- * @inode_init_security:
- *	Obtain the security attribute name suffix and value to set on a newly
- *	created inode and set up the incore security field for the new inode.
- *	This hook is called by the fs code as part of the inode creation
- *	transaction and provides for atomic labeling of the inode, unlike
- *	the post_create/mkdir/... hooks called by the VFS.  The hook function
- *	is expected to allocate the name and value via kmalloc, with the caller
- *	being responsible for calling kfree after using them.
- *	If the security module does not use security attributes or does
- *	not wish to put a security attribute on this particular inode,
- *	then it should return -EOPNOTSUPP to skip this processing.
- *	@inode contains the inode structure of the newly created inode.
- *	@dir contains the inode structure of the parent directory.
- *	@qstr contains the last path component of the new object
- *	@name will be set to the allocated name suffix (e.g. selinux).
- *	@value will be set to the allocated attribute value.
- *	@len will be set to the length of the value.
- *	Returns 0 if @name and @value have been successfully set,
- *		-EOPNOTSUPP if no security attribute is needed, or
- *		-ENOMEM on memory allocation failure.
- * @inode_create:
- *	Check permission to create a regular file.
- *	@dir contains inode structure of the parent of the new file.

+ * @s: Pointer to seqcount_latch_t
+ *
+ * The latch technique is a multiversion concurrency control method that allows
+ * queries during non-atomic modifications. If you can guarantee queries never
+ * interrupt the modification -- e.g. the concurrency is strictly between CPUs
+ * -- you most likely do not need this.
+ *
+ * Where the traditional RCU/lockless data structures rely on atomic
+ * modifications to ensure queries observe either the old or the new state the
+ * latch allows the same for non-atomic updates. The trade-off is doubling the
+ * cost of storage; we have to maintain two copies of the entire data
+ * structure.
+ *
+ * Very simply put: we first modify one copy and then the other. This ensures
+ * there is always one copy in a stable state, ready to give us an answer.
+ *
+ * The basic form is a data structure like::
+ *
+ *	struct latch_struct {
+ *		seqcount_latch_t	seq;
+ *		struct data_struct	data[2];
+ *	};
+ *
+ * Where a modification, which is assumed to be externally serialized, does the
+ * following::
+ *
+ *	void latch_modify(struct latch_struct *latch, ...)
+ *	{
+ *		smp_wmb();	// Ensure that the last data[1] update is visible
+ *		latch->seq.sequence++;
+ *		smp_wmb();	// Ensure that the seqcount update is visible
+ *
+ *		modify(latch->data[0], ...);
+ *
+ *		smp_wmb();	// Ensure that the data[0] update is visible
+ *		latch->seq.sequence++;
+ *		smp_wmb();	// Ensure that the seqcount update is visible
+ *
+ *		modify(latch->data[1], ...);
+ *	}
+ *
+ * The query will have a form like::
+ *
+ *	struct entry *latch_query(struct latch_struct *latch, ...)
+ *	{
+ *		struct entry *entry;
+ *		unsigned seq, idx;
+ *
+ *		do {
+ *			seq = raw_read_seqcount_latch(&latch->seq);
+ *
+ *			idx = seq & 0x01;
+ *			entry = data_query(latch->data[idx], ...);
+ *
+ *		// This includes needed smp_rmb()
+ *		} while (read_seqcount_latch_retry(&latch->seq, seq));
+ *
+ *		return entry;
+ *	}
+ *
+ * So during the modification, queries are first redirected to data[1]. Then we
+ * modify data[0]. When that is complete, we redirect queries back to data[0]
+ * and we can modify data[1].
+ *
+ * NOTE:
+ *
+ *	The non-requirement for atomic modifications does _NOT_ include
+ *	the publishing of new entries in the case where data is a dynamic
+ *	data structure.
+ *
+ *	An iteration might start in data[0] and get suspended long enough
+ *	to miss an entire modification sequence, once it resumes it might
+ *	observe the new entry.
+ *
+ * NOTE2:
+ *
+ *	When data is a dynamic data structure; one should use regular RCU
+ *	patterns to manage the lifetimes of the objects within.

+ *
+ * @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.
+ *	Interrupts: caller dependent.
+ *
+ * @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

+/**
+ * DOC: skb checksums
+ *
+ * The interface for checksum offload between the stack and networking drivers
+ * is as follows...
+ *
+ * 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.
+ *
+ * .. 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
+ *
+ *   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. &sk_buff.csum is still undefined in this case
+ *   though. A driver or device must never modify the checksum field in the
+ *   packet even if checksum is verified.
+ *
+ *   %CHECKSUM_UNNECESSARY is applicable to following protocols:
+ *
+ *     - TCP: IPv6 and IPv4.
+ *     - UDP: IPv4 and IPv6. A device may apply CHECKSUM_UNNECESSARY to a
+ *       zero UDP checksum for either IPv4 or IPv6, the networking stack
+ *       may perform further validation in this case.
+ *     - GRE: only if the checksum is present in the header.
+ *     - SCTP: indicates the CRC in SCTP header has been validated.
+ *     - FCOE: indicates the CRC in FC frame has been validated.
+ *
+ *   &sk_buff.csum_level indicates the number of consecutive checksums found in
+ *   the packet minus one that have been verified as %CHECKSUM_UNNECESSARY.
+ *   For instance if a device receives an IPv6->UDP->GRE->IPv4->TCP packet
+ *   and a device is able to verify the checksums for UDP (possibly zero),
+ *   GRE (checksum flag is set) and TCP, &sk_buff.csum_level would be set to
+ *   two. If the device were only able to verify the UDP checksum and not
+ *   GRE, either because it doesn't support GRE checksum or because GRE
+ *   checksum is bad, skb->csum_level would be set to zero (TCP checksum is
+ *   not considered in this case).
+ *
+ * - %CHECKSUM_COMPLETE
+ *
+ *   This is the most generic way. The device supplied checksum of the _whole_
+ *   packet as seen by netif_rx() and fills in &sk_buff.csum. This means the
+ *   hardware doesn't need to parse L3/L4 headers to implement this.
+ *
+ *   Notes:
+ *
+ *   - Even if device supports only some protocols, but is able to produce
+ *     skb->csum, it MUST use CHECKSUM_COMPLETE, not CHECKSUM_UNNECESSARY.
+ *   - CHECKSUM_COMPLETE is not applicable to SCTP and FCoE protocols.
+ *
+ * - %CHECKSUM_PARTIAL
+ *
+ *   A checksum is set up to be offloaded to a device as described in the
+ *   output description for CHECKSUM_PARTIAL. This may occur on a packet
+ *   received directly from another Linux OS, e.g., a virtualized Linux kernel
+ *   on the same host, or it may be set in the input path in GRO or remote
+ *   checksum offload. For the purposes of checksum verification, the checksum
+ *   referred to by skb->csum_start + skb->csum_offset and any preceding
+ *   checksums in the packet are considered verified. Any checksums in the
+ *   packet that are after the checksum being offloaded are not considered to
+ *   be verified.
+ *
+ * Checksumming on transmit for non-GSO
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * The stack requests checksum offload in the &sk_buff.ip_summed for a packet.
+ * Values are:
+ *
+ * - %CHECKSUM_PARTIAL
+ *
+ *   The driver is required to checksum the packet as seen by hard_start_xmit()
+ *   from &sk_buff.csum_start up to the end, and to record/write the checksum at
+ *   offset &sk_buff.csum_start + &sk_buff.csum_offset.
+ *   A driver may verify that the
+ *   csum_start and csum_offset values are valid values given the length and
+ *   offset of the packet, but it should not attempt to validate that the
+ *   checksum refers to a legitimate transport layer checksum -- it is the
+ *   purview of the stack to validate that csum_start and csum_offset are set
+ *   correctly.
+ *
+ *   When the stack requests checksum offload for a packet, the driver MUST
+ *   ensure that the checksum is set correctly. A driver can either offload the
+ *   checksum calculation to the device, or call skb_checksum_help (in the case
+ *   that the device does not support offload for a particular checksum).
+ *
+ *   %NETIF_F_IP_CSUM and %NETIF_F_IPV6_CSUM are being deprecated in favor of
+ *   %NETIF_F_HW_CSUM. New devices should use %NETIF_F_HW_CSUM to indicate
+ *   checksum offload capability.
+ *   skb_csum_hwoffload_help() can be called to resolve %CHECKSUM_PARTIAL based
+ *   on network device checksumming capabilities: if a packet does not match
+ *   them, skb_checksum_help() or skb_crc32c_help() (depending on the value of
+ *   &sk_buff.csum_not_inet, see :ref:`crc`)
+ *   is called to resolve the checksum.
+ *
+ * - %CHECKSUM_NONE
+ *
+ *   The skb was already checksummed by the protocol, or a checksum is not
+ *   required.
+ *
+ * - %CHECKSUM_UNNECESSARY
+ *
+ *   This has the same meaning as CHECKSUM_NONE for checksum offload on
+ *   output.
+ *
+ * - %CHECKSUM_COMPLETE
+ *
+ *   Not used in checksum output. If a driver observes a packet with this value
+ *   set in skbuff, it should treat the packet as if %CHECKSUM_NONE were set.
+ *
+ * .. _crc:
+ *
+ * Non-IP checksum (CRC) offloads
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * .. flat-table::
+ *   :widths: 1 10
+ *
+ *   * - %NETIF_F_SCTP_CRC
+ *     - This feature indicates that a device is capable of
+ *	 offloading the SCTP CRC in a packet. To perform this offload the stack
+ *	 will set csum_start and csum_offset accordingly, set ip_summed to
+ *	 %CHECKSUM_PARTIAL and set csum_not_inet to 1, to provide an indication
+ *	 in the skbuff that the %CHECKSUM_PARTIAL refers to CRC32c.
+ *	 A driver that supports both IP checksum offload and SCTP CRC32c offload
+ *	 must verify which offload is configured for a packet by testing the
+ *	 value of &sk_buff.csum_not_inet; skb_crc32c_csum_help() is provided to
+ *	 resolve %CHECKSUM_PARTIAL on skbs where csum_not_inet is set to 1.
+ *
+ *   * - %NETIF_F_FCOE_CRC
+ *     - This feature indicates that a device is capable of offloading the FCOE
+ *	 CRC in a packet. To perform this offload the stack will set ip_summed
+ *	 to %CHECKSUM_PARTIAL and set csum_start and csum_offset
+ *	 accordingly. Note that there is no indication in the skbuff that the
+ *	 %CHECKSUM_PARTIAL refers to an FCOE checksum, so a driver that supports
+ *	 both IP checksum offload and FCOE CRC offload must verify which offload
+ *	 is configured for a packet, presumably by inspecting packet headers.
+ *
+ * Checksumming on output with GSO
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * In the case of a GSO packet (skb_is_gso() is true), checksum offload
+ * is implied by the SKB_GSO_* flags in gso_type. Most obviously, if the
+ * gso_type is %SKB_GSO_TCPV4 or %SKB_GSO_TCPV6, TCP checksum offload as
+ * part of the GSO operation is implied. If a checksum is being offloaded
+ * with GSO then ip_summed is %CHECKSUM_PARTIAL, and both csum_start and
+ * csum_offset are set to refer to the outermost checksum being offloaded
+ * (two offloaded checksums are possible with UDP encapsulation).

- *	NETIF_F_IPV6_CSUM about as dumb as the last one but does IPv6 instead.
- *
- *	UNNECESSARY: device will do per protocol specific csum. Protocol drivers
- *	that do not want net to perform the checksum calculation should use
- *	this flag in their outgoing skbs.
- *	NETIF_F_FCOE_CRC  this indicates the device can do FCoE FC CRC

 /**
- * kmalloc - allocate memory
+ * kmalloc - allocate kernel memory
  * @size: how many bytes of memory are required.
- * @flags: the type of memory to allocate.
- *
- * The @flags argument may be one of:
+ * @flags: describe the allocation context
  *
- * %GFP_USER - Allocate memory on behalf of user.  May sleep.
- *
- * %GFP_KERNEL - Allocate normal kernel ram.  May sleep.
+ * kmalloc is the normal method of allocating memory
+ * for objects smaller than page size in the kernel.
  *
- * %GFP_ATOMIC - Allocation will not sleep.  May use emergency pools.
- *   For example, use this inside interrupt handlers.
+ * The allocated object address is aligned to at least ARCH_KMALLOC_MINALIGN
+ * bytes. For @size of power of two bytes, the alignment is also guaranteed
+ * to be at least to the size.
  *
- * %GFP_HIGHUSER - Allocate pages from high memory.
+ * The @flags argument may be one of the GFP flags defined at
+ * include/linux/gfp_types.h and described at
+ * :ref:`Documentation/core-api/mm-api.rst <mm-api-gfp-flags>`
  *
- * %GFP_NOIO - Do not do any I/O at all while trying to get memory.
+ * The recommended usage of the @flags is described at
+ * :ref:`Documentation/core-api/memory-allocation.rst <memory_allocation>`
  *
- * %GFP_NOFS - Do not make any fs calls while trying to get memory.
+ * Below is a brief outline of the most useful GFP flags
  *
- * %GFP_NOWAIT - Allocation will not sleep.
+ * %GFP_KERNEL
+ *	Allocate normal kernel ram. May sleep.
  *
- * %GFP_THISNODE - Allocate node-local memory only.
+ * %GFP_NOWAIT
+ *	Allocation will not sleep.
  *
- * %GFP_DMA - Allocation suitable for DMA.
- *   Should only be used for kmalloc() caches. Otherwise, use a
- *   slab created with SLAB_DMA.
+ * %GFP_ATOMIC
+ *	Allocation will not sleep.  May use emergency pools.
  *
  * Also it is possible to set different flags by OR'ing
  * in one or more of the following additional @flags:
  *
- * %__GFP_COLD - Request cache-cold pages instead of
- *   trying to return cache-warm pages.
- *
- * %__GFP_HIGH - This allocation has high priority and may use emergency pools.
+ * %__GFP_ZERO
+ *	Zero the allocated memory before returning. Also see kzalloc().
  *
- * %__GFP_NOFAIL - Indicate that this allocation is in no way allowed to fail
- *   (think twice before using).
+ * %__GFP_HIGH
+ *	This allocation has high priority and may use emergency pools.
  *
- * %__GFP_NORETRY - If memory is not immediately available,
- *   then give up at once.
+ * %__GFP_NOFAIL
+ *	Indicate that this allocation is in no way allowed to fail
+ *	(think twice before using).
  *
- * %__GFP_NOWARN - If allocation fails, don't issue any warnings.
+ * %__GFP_NORETRY
+ *	If memory is not immediately available,
+ *	then give up at once.
  *
- * %__GFP_REPEAT - If allocation fails initially, try once more before failing.
+ * %__GFP_NOWARN
+ *	If allocation fails, don't issue any warnings.
  *
- * There are other flags available as well, but these are not intended
- * for general use, and so are not documented here. For a full list of
- * potential flags, always refer to linux/gfp.h.
- *
- * kmalloc is the normal method of allocating memory
- * in the kernel.
+ * %__GFP_RETRY_MAYFAIL
+ *	Try really hard to succeed the allocation but fail
+ *	eventually.

+ * Static call support
+ *
+ * Static calls use code patching to hard-code function pointers into direct
+ * branch instructions. They give the flexibility of function pointers, but
+ * with improved performance. This is especially important for cases where
+ * retpolines would otherwise be used, as retpolines can significantly impact
+ * performance.
+ *
+ *
+ * API overview:
+ *
+ *   DECLARE_STATIC_CALL(name, func);
+ *   DEFINE_STATIC_CALL(name, func);
+ *   DEFINE_STATIC_CALL_NULL(name, typename);
+ *   DEFINE_STATIC_CALL_RET0(name, typename);
+ *
+ *   __static_call_return0;
+ *
+ *   static_call(name)(args...);
+ *   static_call_cond(name)(args...);
+ *   static_call_update(name, func);
+ *   static_call_query(name);
+ *
+ *   EXPORT_STATIC_CALL{,_TRAMP}{,_GPL}()
+ *
+ * Usage example:
+ *
+ *   # Start with the following functions (with identical prototypes):
+ *   int func_a(int arg1, int arg2);
+ *   int func_b(int arg1, int arg2);
+ *
+ *   # Define a 'my_name' reference, associated with func_a() by default
+ *   DEFINE_STATIC_CALL(my_name, func_a);
+ *
+ *   # Call func_a()
+ *   static_call(my_name)(arg1, arg2);
+ *
+ *   # Update 'my_name' to point to func_b()
+ *   static_call_update(my_name, &func_b);
+ *
+ *   # Call func_b()
+ *   static_call(my_name)(arg1, arg2);
+ *
+ *
+ * Implementation details:
+ *
+ *   This requires some arch-specific code (CONFIG_HAVE_STATIC_CALL).
+ *   Otherwise basic indirect calls are used (with function pointers).
+ *
+ *   Each static_call() site calls into a trampoline associated with the name.
+ *   The trampoline has a direct branch to the default function.  Updates to a
+ *   name will modify the trampoline's branch destination.
+ *
+ *   If the arch has CONFIG_HAVE_STATIC_CALL_INLINE, then the call sites
+ *   themselves will be patched at runtime to call the functions directly,
+ *   rather than calling through the trampoline.  This requires objtool or a
+ *   compiler plugin to detect all the static_call() sites and annotate them
+ *   in the .static_call_sites section.
+ *
+ *
+ * Notes on NULL function pointers:
+ *
+ *   Static_call()s support NULL functions, with many of the caveats that
+ *   regular function pointers have.
+ *
+ *   Clearly calling a NULL function pointer is 'BAD', so too for
+ *   static_call()s (although when HAVE_STATIC_CALL it might not be immediately
+ *   fatal). A NULL static_call can be the result of:
+ *
+ *     DECLARE_STATIC_CALL_NULL(my_static_call, void (*)(int));
+ *
+ *   which is equivalent to declaring a NULL function pointer with just a
+ *   typename:
+ *
+ *     void (*my_func_ptr)(int arg1) = NULL;
+ *
+ *   or using static_call_update() with a NULL function. In both cases the
+ *   HAVE_STATIC_CALL implementation will patch the trampoline with a RET
+ *   instruction, instead of an immediate tail-call JMP. HAVE_STATIC_CALL_INLINE
+ *   architectures can patch the trampoline call to a NOP.
+ *
+ *   In all cases, any argument evaluation is unconditional. Unlike a regular
+ *   conditional function pointer call:
+ *
+ *     if (my_func_ptr)
+ *         my_func_ptr(arg1)
+ *
+ *   where the argument evaludation also depends on the pointer value.
+ *
+ *   When calling a static_call that can be NULL, use:
+ *
+ *     static_call_cond(name)(arg1);
+ *
+ *   which will include the required value tests to avoid NULL-pointer
+ *   dereferences.
+ *
+ *   To query which function is currently set to be called, use:
+ *
+ *   func = static_call_query(name);
+ *
+ *
+ * DEFINE_STATIC_CALL_RET0 / __static_call_return0:
+ *
+ *   Just like how DEFINE_STATIC_CALL_NULL() / static_call_cond() optimize the
+ *   conditional void function call, DEFINE_STATIC_CALL_RET0 /
+ *   __static_call_return0 optimize the do nothing return 0 function.
+ *
+ *   This feature is strictly UB per the C standard (since it casts a function
+ *   pointer to a different signature) and relies on the architecture ABI to
+ *   make things work. In particular it relies on Caller Stack-cleanup and the
+ *   whole return register being clobbered for short return values. All normal
+ *   CDECL style ABIs conform.
+ *
+ *   In particular the x86_64 implementation replaces the 5 byte CALL
+ *   instruction at the callsite with a 5 byte clear of the RAX register,
+ *   completely eliding any function call overhead.
+ *
+ *   Notably argument setup is unconditional.
+ *
+ *
+ * EXPORT_STATIC_CALL() vs EXPORT_STATIC_CALL_TRAMP():
+ *
+ *   The difference is that the _TRAMP variant tries to only export the
+ *   trampoline with the result that a module can use static_call{,_cond}() but
+ *   not static_call_update().

+ *
+ * The generated function is defined as ``static int name(struct

+ * returning the status of the request, which is zero on success and negative
+ * on failure. The ``ctrl`` parameter is the controller via which the request
+ * is sent, ``tid`` the target ID for the request, and ``iid`` the instance ID.
+ * The request argument is specified via the ``arg`` pointer. The request's
+ * return value is written to the memory pointed to by the ``ret`` parameter.

+ *
+ * Mainly, this is accomplished by two things. Firstly not allowing swake_up_all
+ * from IRQ disabled, and dropping the lock upon every wakeup, giving a higher
+ * priority task a chance to run.
+ *
+ * Secondly, we had to drop a fair number of features of the other waitqueue
+ * code; notably:
+ *
+ *  - mixing INTERRUPTIBLE and UNINTERRUPTIBLE sleeps on the same waitqueue;
+ *    all wakeups are TASK_NORMAL in order to avoid O(n) lookups for the right
+ *    sleeper state.
+ *
+ *  - the !exclusive mode; because that leads to O(n) wakeups, everything is
+ *    exclusive. As such swake_up_one will only ever awake _one_ waiter.
+ *
+ *  - custom wake callback functions; because you cannot give any guarantees
+ *    about random code. This also allows swait to be used in RT, such that
+ *    raw spinlock can be used for the swait queue head.
+ *
+ * As a side effect of these; the data structures are slimmer albeit more ad-hoc.
+ * For all the above, note that simple wait queues should _only_ be used under
+ * very specific realtime constraints -- it is best to stick with the regular
+ * wait queues in most cases.

- *
- * This copyrighted material is made available to anyone wishing to use,
- * modify, copy, or redistribute it subject to the terms and conditions
- * of the GNU General Public License v.2.
- *
- * 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.

- * 						- TYT, 9/14/92
+ * @kref: reference counting by tty_kref_get() and tty_kref_put(), reaching zero
+ *	  frees the structure
+ * @dev: class device or %NULL (e.g. ptys, serdev)
+ * @driver: &struct tty_driver operating this tty
+ * @ops: &struct tty_operations of @driver for this tty (open, close, etc.)
+ * @index: index of this tty (e.g. to construct @name like tty12)
+ * @ldisc_sem: protects line discipline changes (@ldisc) -- lock tty not pty
+ * @ldisc: the current line discipline for this tty (n_tty by default)
+ * @atomic_write_lock: protects against concurrent writers, i.e. locks
+ *		       @write_cnt, @write_buf and similar
+ * @legacy_mutex: leftover from history (BKL -> BTM -> @legacy_mutex),
+ *		  protecting several operations on this tty
+ * @throttle_mutex: protects against concurrent tty_throttle_safe() and
+ *		    tty_unthrottle_safe() (but not tty_unthrottle())
+ * @termios_rwsem: protects @termios and @termios_locked
+ * @winsize_mutex: protects @winsize
+ * @termios: termios for the current tty, copied from/to @driver.termios
+ * @termios_locked: locked termios (by %TIOCGLCKTRMIOS and %TIOCSLCKTRMIOS
+ *		    ioctls)
+ * @name: name of the tty constructed by tty_line_name() (e.g. ttyS3)
+ * @flags: bitwise OR of %TTY_THROTTLED, %TTY_IO_ERROR, ...
+ * @count: count of open processes, reaching zero cancels all the work for
+ *	   this tty and drops a @kref too (but does not free this tty)
+ * @winsize: size of the terminal "window" (cf. @winsize_mutex)
+ * @flow: flow settings grouped together, see also @flow.unused
+ * @flow.lock: lock for @flow members
+ * @flow.stopped: tty stopped/started by stop_tty()/start_tty()
+ * @flow.tco_stopped: tty stopped/started by %TCOOFF/%TCOON ioctls (it has
+ *		      precedence over @flow.stopped)
+ * @flow.unused: alignment for Alpha, so that no members other than @flow.* are
+ *		 modified by the same 64b word store. The @flow's __aligned is
+ *		 there for the very same reason.
+ * @ctrl: control settings grouped together, see also @ctrl.unused
+ * @ctrl.lock: lock for @ctrl members
+ * @ctrl.pgrp: process group of this tty (setpgrp(2))
+ * @ctrl.session: session of this tty (setsid(2)). Writes are protected by both
+ *		  @ctrl.lock and @legacy_mutex, readers must use at least one of
+ *		  them.
+ * @ctrl.pktstatus: packet mode status (bitwise OR of %TIOCPKT_ constants)
+ * @ctrl.packet: packet mode enabled
+ * @ctrl.unused: alignment for Alpha, see @flow.unused for explanation
+ * @hw_stopped: not controlled by the tty layer, under @driver's control for CTS
+ *		handling
+ * @receive_room: bytes permitted to feed to @ldisc without any being lost
+ * @flow_change: controls behavior of throttling, see tty_throttle_safe() and
+ *		 tty_unthrottle_safe()
+ * @link: link to another pty (master -> slave and vice versa)
+ * @fasync: state for %O_ASYNC (for %SIGIO); managed by fasync_helper()
+ * @write_wait: concurrent writers are waiting in this queue until they are
+ *		allowed to write
+ * @read_wait: readers wait for data in this queue
+ * @hangup_work: normally a work to perform a hangup (do_tty_hangup()); while
+ *		 freeing the tty, (re)used to release_one_tty()
+ * @disc_data: pointer to @ldisc's private data (e.g. to &struct n_tty_data)
+ * @driver_data: pointer to @driver's private data (e.g. &struct uart_state)
+ * @files_lock:	protects @tty_files list
+ * @tty_files: list of (re)openers of this tty (i.e. linked &struct
+ *	       tty_file_private)
+ * @closing: when set during close, n_tty processes only START & STOP chars
+ * @write_buf: temporary buffer used during tty_write() to copy user data to
+ * @write_cnt: count of bytes written in tty_write() to @write_buf
+ * @SAK_work: if the tty has a pending do_SAK, it is queued here
+ * @port: persistent storage for this device (i.e. &struct tty_port)
+ *
+ * All of the state associated with a tty while the tty is open. Persistent
+ * storage for tty devices is referenced here as @port and is documented in

+ *
+ * These bits are used in the :c:member:`tty_struct.flags` field.
  *
  * So that interrupts won't be able to mess up the queues,
  * copy_to_cooked must be atomic with respect to itself, as must
  * tty->write.  Thus, you must use the inline functions set_bit() and
  * clear_bit() to make things atomic.
+ *
+ * TTY_THROTTLED
+ *	Driver input is throttled. The ldisc should call
+ *	:c:member:`tty_driver.unthrottle()` in order to resume reception when
+ *	it is ready to process more data (at threshold min).
+ *
+ * TTY_IO_ERROR
+ *	If set, causes all subsequent userspace read/write calls on the tty to
+ *	fail, returning -%EIO. (May be no ldisc too.)
+ *
+ * TTY_OTHER_CLOSED
+ *	Device is a pty and the other side has closed.
+ *
+ * TTY_EXCLUSIVE
+ *	Exclusive open mode (a single opener).
+ *
+ * TTY_DO_WRITE_WAKEUP
+ *	If set, causes the driver to call the
+ *	:c:member:`tty_ldisc_ops.write_wakeup()` method in order to resume
+ *	transmission when it can accept more data to transmit.
+ *
+ * TTY_LDISC_OPEN
+ *	Indicates that a line discipline is open. For debugging purposes only.
+ *
+ * TTY_PTY_LOCK
+ *	A flag private to pty code to implement %TIOCSPTLCK/%TIOCGPTLCK logic.
+ *
+ * TTY_NO_WRITE_SPLIT
+ *	Prevent driver from splitting up writes into smaller chunks (preserve
+ *	write boundaries to driver).
+ *
+ * TTY_HUPPED
+ *	The TTY was hung up. This is set post :c:member:`tty_driver.hangup()`.
+ *
+ * TTY_HUPPING
+ *	The TTY is in the process of hanging up to abort potential readers.
+ *
+ * TTY_LDISC_CHANGING
+ *	Line discipline for this TTY is being changed. I/O should not block
+ *	when this is set. Use tty_io_nonblock() to check.
+ *
+ * TTY_LDISC_HALTED
+ *	Line discipline for this TTY was stopped. No work should be queued to
+ *	this ldisc.

+ * struct tty_ldisc_ops - ldisc operations
+ *
+ * @name: name of this ldisc rendered in /proc/tty/ldiscs
+ * @num: ``N_*`` number (%N_TTY, %N_HDLC, ...) reserved to this ldisc
+ *
+ * @open: [TTY] ``int ()(struct tty_struct *tty)``
+ *
+ *	This function is called when the line discipline is associated with the
+ *	@tty. No other call into the line discipline for this tty will occur
+ *	until it completes successfully. It should initialize any state needed
+ *	by the ldisc, and set @tty->receive_room to the maximum amount of data
+ *	the line discipline is willing to accept from the driver with a single
+ *	call to @receive_buf(). Returning an error will prevent the ldisc from
+ *	being attached.
+ *
+ *	Can sleep.
+ *
+ * @close: [TTY] ``void ()(struct tty_struct *tty)``
+ *
+ *	This function is called when the line discipline is being shutdown,
+ *	either because the @tty is being closed or because the @tty is being
+ *	changed to use a new line discipline. At the point of execution no
+ *	further users will enter the ldisc code for this tty.
+ *
+ *	Can sleep.
+ *
+ * @flush_buffer: [TTY] ``void ()(struct tty_struct *tty)``
+ *
+ *	This function instructs the line discipline to clear its buffers of any
+ *	input characters it may have queued to be delivered to the user mode
+ *	process. It may be called at any point between open and close.
+ *
+ * @read: [TTY] ``ssize_t ()(struct tty_struct *tty, struct file *file,
+ *		unsigned char *buf, size_t nr)``
+ *
+ *	This function is called when the user requests to read from the @tty.
+ *	The line discipline will return whatever characters it has buffered up
+ *	for the user. If this function is not defined, the user will receive
+ *	an %EIO error. Multiple read calls may occur in parallel and the ldisc
+ *	must deal with serialization issues.
+ *
+ *	Can sleep.
+ *
+ * @write: [TTY] ``ssize_t ()(struct tty_struct *tty, struct file *file,
+ *		const unsigned char *buf, size_t nr)``
+ *
+ *	This function is called when the user requests to write to the @tty.
+ *	The line discipline will deliver the characters to the low-level tty
+ *	device for transmission, optionally performing some processing on the
+ *	characters first. If this function is not defined, the user will
+ *	receive an %EIO error.
+ *
+ *	Can sleep.
+ *
+ * @ioctl: [TTY] ``int ()(struct tty_struct *tty, unsigned int cmd,
+ *		unsigned long arg)``
+ *
+ *	This function is called when the user requests an ioctl which is not
+ *	handled by the tty layer or the low-level tty driver. It is intended
+ *	for ioctls which affect line discpline operation.  Note that the search
+ *	order for ioctls is (1) tty layer, (2) tty low-level driver, (3) line
+ *	discpline. So a low-level driver can "grab" an ioctl request before
+ *	the line discpline has a chance to see it.
+ *
+ * @compat_ioctl: [TTY] ``int ()(struct tty_struct *tty, unsigned int cmd,
+ *		unsigned long arg)``
+ *
+ *	Process ioctl calls from 32-bit process on 64-bit system.
+ *
+ *	Note that only ioctls that are neither "pointer to compatible
+ *	structure" nor tty-generic.  Something private that takes an integer or
+ *	a pointer to wordsize-sensitive structure belongs here, but most of
+ *	ldiscs will happily leave it %NULL.
+ *
+ * @set_termios: [TTY] ``void ()(struct tty_struct *tty, const struct ktermios *old)``
+ *
+ *	This function notifies the line discpline that a change has been made
+ *	to the termios structure.
+ *
+ * @poll: [TTY] ``int ()(struct tty_struct *tty, struct file *file,
+ *		  struct poll_table_struct *wait)``
+ *
+ *	This function is called when a user attempts to select/poll on a @tty
+ *	device. It is solely the responsibility of the line discipline to
+ *	handle poll requests.
+ *
+ * @hangup: [TTY] ``void ()(struct tty_struct *tty)``
+ *
+ *	Called on a hangup. Tells the discipline that it should cease I/O to
+ *	the tty driver. The driver should seek to perform this action quickly
+ *	but should wait until any pending driver I/O is completed. No further
+ *	calls into the ldisc code will occur.
+ *
+ *	Can sleep.
+ *
+ * @receive_buf: [DRV] ``void ()(struct tty_struct *tty,
+ *		       const unsigned char *cp, const char *fp, int count)``
+ *
+ *	This function is called by the low-level tty driver to send characters
+ *	received by the hardware to the line discpline for processing. @cp is
+ *	a pointer to the buffer of input character received by the device. @fp
+ *	is a pointer to an array of flag bytes which indicate whether a
+ *	character was received with a parity error, etc. @fp may be %NULL to
+ *	indicate all data received is %TTY_NORMAL.
+ *
+ * @write_wakeup: [DRV] ``void ()(struct tty_struct *tty)``
+ *
+ *	This function is called by the low-level tty driver to signal that line
+ *	discpline should try to send more characters to the low-level driver
+ *	for transmission. If the line discpline does not have any more data to
+ *	send, it can just return. If the line discipline does have some data to
+ *	send, please arise a tasklet or workqueue to do the real data transfer.
+ *	Do not send data in this hook, it may lead to a deadlock.
+ *
+ * @dcd_change: [DRV] ``void ()(struct tty_struct *tty, bool active)``
+ *
+ *	Tells the discipline that the DCD pin has changed its status. Used
+ *	exclusively by the %N_PPS (Pulse-Per-Second) line discipline.
+ *
+ * @receive_buf2: [DRV] ``int ()(struct tty_struct *tty,
+ *			const unsigned char *cp, const char *fp, int count)``
+ *
+ *	This function is called by the low-level tty driver to send characters
+ *	received by the hardware to the line discpline for processing. @cp is a
+ *	pointer to the buffer of input character received by the device.  @fp
+ *	is a pointer to an array of flag bytes which indicate whether a
+ *	character was received with a parity error, etc. @fp may be %NULL to
+ *	indicate all data received is %TTY_NORMAL. If assigned, prefer this
+ *	function for automatic flow control.
+ *
+ * @lookahead_buf: [DRV] ``void ()(struct tty_struct *tty,
+ *			const unsigned char *cp, const char *fp, int count)``
+ *
+ *	This function is called by the low-level tty driver for characters
+ *	not eaten by ->receive_buf() or ->receive_buf2(). It is useful for
+ *	processing high-priority characters such as software flow-control
+ *	characters that could otherwise get stuck into the intermediate
+ *	buffer until tty has room to receive them. Ldisc must be able to
+ *	handle later a ->receive_buf() or ->receive_buf2() call for the
+ *	same characters (e.g. by skipping the actions for high-priority
+ *	characters already handled by ->lookahead_buf()).
+ *
+ * @owner: module containting this ldisc (for reference counting)
+ *
+ * This structure defines the interface between the tty line discipline
+ * implementation and the tty routines. The above routines can be defined.
+ * Unless noted otherwise, they are optional, and can be filled in with a %NULL
+ * pointer.
+ *
+ * Hooks marked [TTY] are invoked from the TTY core, the [DRV] ones from the
+ * tty_driver side.

- * To properly implement 64bits network statistics on 32bit and 64bit hosts,
- * we provide a synchronization point, that is a noop on 64bit or UP kernels.
+ * Protect against 64-bit values tearing on 32-bit architectures. This is
+ * typically used for statistics read/update in different subsystems.
  *
  * Key points :
- * 1) Use a seqcount on SMP 32bits, with low overhead.
- * 2) Whole thing is a noop on 64bit arches or UP kernels.
- * 3) Write side must ensure mutual exclusion or one seqcount update could

+ * -  Use a seqcount on 32-bit
+ * -  The whole thing is a no-op on 64-bit architectures.
+ *
+ * Usage constraints:
+ *
+ * 1) Write side must ensure mutual exclusion, or one seqcount update could
  *    be lost, thus blocking readers forever.
- *    If this synchronization point is not a mutex, but a spinlock or
- *    spinlock_bh() or disable_bh() :
- * 3.1) Write side should not sleep.
- * 3.2) Write side should not allow preemption.
- * 3.3) If applicable, interrupts should be disabled.
  *
- * 4) If reader fetches several counters, there is no guarantee the whole values
- *    are consistent (remember point 1) : this is a noop on 64bit arches anyway)
+ * 2) Write side must disable preemption, or a seqcount reader can preempt the
+ *    writer and also spin forever.
  *
- * 5) readers are allowed to sleep or be preempted/interrupted : They perform
- *    pure reads. But if they have to fetch many values, it's better to not allow
- *    preemptions/interruptions to avoid many retries.
+ * 3) Write side must use the _irqsave() variant if other writers, or a reader,
+ *    can be invoked from an IRQ context. On 64bit systems this variant does not
+ *    disable interrupts.
  *
- * 6) If counter might be written by an interrupt, readers should block interrupts.
- *    (On UP, there is no seqcount_t protection, a reader allowing interrupts could
- *     read partial values)
+ * 4) If reader fetches several counters, there is no guarantee the whole values
+ *    are consistent w.r.t. each other (remember point #2: seqcounts are not
+ *    used for 64bit architectures).
  *
- * 7) For softirq uses, readers can use u64_stats_fetch_begin_bh() and
- *    u64_stats_fetch_retry_bh() helpers

+ * Architectures should provide two primitives (raw_copy_{to,from}_user())
+ * and get rid of their private instances of copy_{to,from}_user() and
+ * __copy_{to,from}_user{,_inatomic}().
+ *
+ * raw_copy_{to,from}_user(to, from, size) should copy up to size bytes and
+ * return the amount left to copy.  They should assume that access_ok() has
+ * already been checked (and succeeded); they should *not* zero-pad anything.
+ * No KASAN or object size checks either - those belong here.
+ *
+ * Both of these functions should attempt to copy size bytes starting at from
+ * into the area starting at to.  They must not fetch or store anything
+ * outside of those areas.  Return value must be between 0 (everything
+ * copied successfully) and size (nothing copied).
+ *
+ * If raw_copy_{to,from}_user(to, from, size) returns N, size - N bytes starting
+ * at to must become equal to the bytes fetched from the corresponding area
+ * starting at from.  All data past to + size - N must be left unmodified.
+ *
+ * If copying succeeds, the return value must be 0.  If some data cannot be
+ * fetched, it is permitted to copy less than had been fetched; the only
+ * hard requirement is that not storing anything at all (i.e. returning size)
+ * should happen only when nothing could be copied.  In other words, you don't
+ * have to squeeze as much as possible - it is allowed, but not necessary.
+ *
+ * For raw_copy_from_user() to always points to kernel memory and no faults
+ * on store should happen.  Interpretation of from is affected by set_fs().
+ * For raw_copy_to_user() it's the other way round.
+ *
+ * Both can be inlined - it's up to architectures whether it wants to bother
+ * with that.  They should not be used directly; they are used to implement
+ * the 6 functions (copy_{to,from}_user(), __copy_{to,from}_user_inatomic())
+ * that are used instead.  Out of those, __... ones are inlined.  Plain
+ * copy_{to,from}_user() might or might not be inlined.  If you want them
+ * inlined, have asm/uaccess.h define INLINE_COPY_{TO,FROM}_USER.
+ *
+ * NOTE: only copy_from_user() zero-pads the destination in case of short copy.
+ * Neither __copy_from_user() nor __copy_from_user_inatomic() zero anything
+ * at all; their callers absolutely must check the return value.
+ *
+ * Biarch ones should also provide raw_copy_in_user() - similar to the above,
+ * but both source and destination are __user pointers (affected by set_fs()
+ * as usual) and both source and destination can trigger faults.

- * Drivers can rely on the fact that the first byte of the request's buffer
- * always corresponds to the first byte of some USB packet, for both

- *
- * Bulk endpoints can queue any amount of data; the transfer is packetized

- * protocols since not all usb hardware can successfully handle zero length
- * packets.  (ZLPs may be explicitly written, and may be implicitly written if
- * the request 'zero' flag is set.)  Bulk endpoints may also be used
- * for interrupt transfers; but the reverse is not true, and some endpoints
- * won't support every interrupt transfer.  (Such as 768 byte packets.)
- *
- * Interrupt-only endpoints are less functional than bulk endpoints, for
- * example by not supporting queueing or not handling buffers that are
- * larger than the endpoint's maxpacket size.  They may also treat data
- * toggle differently.
- *
- * Control endpoints ... after getting a setup() callback, the driver queues
- * one response (even if it would be zero length).  That enables the
- * status ack, after transferring data as specified in the response.  Setup
- * functions may return negative error codes to generate protocol stalls.
- * (Note that some USB device controllers disallow protocol stall responses
- * in some cases.)  When control responses are deferred (the response is
- * written after the setup callback returns), then usb_ep_set_halt() may be
- * used on ep0 to trigger protocol stalls.  Depending on the controller,
- * it may not be possible to trigger a status-stage protocol stall when the
- * data stage is over, that is, from within the response's completion
- * routine.
- *
- * For periodic endpoints, like interrupt or isochronous ones, the usb host
- * arranges to poll once per interval, and the gadget driver usually will

+ *		current-limit detection method for the cc=Rp-def case.
+ *		For example, some tcpcs may include BC1.2 charger detection
+ *		and use that in this case.
+ * @set_cc:	Called to set value of CC pins
+ * @apply_rc:	Optional; Needed to move TCPCI based chipset to APPLY_RC state
+ *		as stated by the TCPCI specification.
+ * @get_cc:	Called to read current CC pin values
+ * @set_polarity:
+ *		Called to set polarity
+ * @set_vconn:	Called to enable or disable VCONN
+ * @set_vbus:	Called to enable or disable VBUS
+ * @set_current_limit:
+ *		Optional; called to set current limit as negotiated
+ *		with partner.
+ * @set_pd_rx:	Called to enable or disable reception of PD messages
+ * @set_roles:	Called to set power and data roles
+ * @start_toggling:
+ *		Optional; if supported by hardware, called to start dual-role
+ *		toggling or single-role connection detection. Toggling stops
+ *		automatically if a connection is established.
+ * @try_role:	Optional; called to set a preferred role
+ * @pd_transmit:Called to transmit PD message
+ * @set_bist_data: Turn on/off bist data mode for compliance testing
+ * @enable_frs:
+ *		Optional; Called to enable/disable PD 3.0 fast role swap.
+ *		Enabling frs is accessory dependent as not all PD3.0
+ *		accessories support fast role swap.
+ * @frs_sourcing_vbus:
+ *		Optional; Called to notify that vbus is now being sourced.
+ *		Low level drivers can perform chip specific operations, if any.
+ * @enable_auto_vbus_discharge:
+ *		Optional; TCPCI spec based TCPC implementations can optionally
+ *		support hardware to autonomously dischrge vbus upon disconnecting
+ *		as sink or source. TCPM signals TCPC to enable the mechanism upon
+ *		entering connected state and signals disabling upon disconnect.
+ * @set_auto_vbus_discharge_threshold:
+ *		Mandatory when enable_auto_vbus_discharge is implemented. TCPM
+ *		calls this function to allow lower levels drivers to program the
+ *		vbus threshold voltage below which the vbus discharge circuit
+ *		will be turned on. requested_vbus_voltage is set to 0 when vbus
+ *		is going to disappear knowingly i.e. during PR_SWAP and
+ *		HARD_RESET etc.
+ * @is_vbus_vsafe0v:
+ *		Optional; TCPCI spec based TCPC implementations are expected to
+ *		detect VSAFE0V voltage level at vbus. When detection of VSAFE0V
+ *		is supported by TCPC, set this callback for TCPM to query
+ *		whether vbus is at VSAFE0V when needed.
+ *		Returns true when vbus is at VSAFE0V, false otherwise.
+ * @set_partner_usb_comm_capable:
+ *              Optional; The USB Communications Capable bit indicates if port
+ *              partner is capable of communication over the USB data lines
+ *              (e.g. D+/- or SS Tx/Rx). Called to notify the status of the bit.
+ * @check_contaminant:
+ *		Optional; The callback is called when CC pins report open status
+ *		at the end of the deboumce period or when the port is still
+ *		toggling. Chip level drivers are expected to check for contaminant
+ *		and call tcpm_clean_port when the port is clean.

- * Life cycle rules: those of the UWB Device.
- *
- * @index:    an index number for this radio controller, as used in the
- *            device name.
- * @version:  version of protocol supported by this device
- * @priv:     Backend implementation; rw with uwb_dev.dev.sem taken.
- * @cmd:      Backend implementation to execute commands; rw and call
- *            only  with uwb_dev.dev.sem taken.
- * @reset:    Hardware reset of radio controller and any PAL controllers.
- * @filter:   Backend implementation to manipulate data to and from device
- *            to be compliant to specification assumed by driver (WHCI
- *            0.95).
- *
- *            uwb_dev.dev.mutex is used to execute commands and update
- *            the corresponding structures; can't use a spinlock
- *            because rc->cmd() can sleep.
- * @ies:         This is a dynamically allocated array cacheing the
- *               IEs (settable by the host) that the beacon of this
- *               radio controller is currently sending.
- *
- *               In reality, we store here the full command we set to
- *               the radio controller (which is basically a command
- *               prefix followed by all the IEs the beacon currently
- *               contains). This way we don't have to realloc and
- *               memcpy when setting it.
- *
- *               We set this up in uwb_rc_ie_setup(), where we alloc
- *               this struct, call get_ie() [so we know which IEs are
- *               currently being sent, if any].
- *
- * @ies_capacity:Amount of space (in bytes) allocated in @ies. The
- *               amount used is given by sizeof(*ies) plus ies->wIELength
- *               (which is a little endian quantity all the time).
- * @ies_mutex:   protect the IE cache
- * @dbg:         information for the debug interface

- * UWB radio controller Event Size Entry (for creating entry tables)

- * Each event/notification has a size which is not necessarily known
- * in advance based on the event code. As well, vendor specific
- * events/notifications will have a size impossible to determine
- * unless we know about the device's specific details.
- *
- * It was way too smart of the spec writers not to think that it would
- * be impossible for a generic driver to skip over vendor specific
- * events/notifications if there are no LENGTH fields in the HEADER of
- * each message...the transaction size cannot be counted on as the
- * spec does not forbid to pack more than one event in a single
- * transaction.
- *
- * Thus, we guess sizes with tables (or for events, when you know the
- * size ahead of time you can use uwb_rc_neh_extra_size*()). We
- * register tables with the known events and their sizes, and then we
- * traverse those tables. For those with variable length, we provide a
- * way to lookup the size inside the event/notification's
- * payload. This allows device-specific event size tables to be
- * registered.
- *
- * @size:   Size of the payload
- *
- * @offset: if != 0, at offset @offset-1 starts a field with a length
- *          that has to be added to @size. The format of the field is
- *          given by @type.
- *
- * @type:   Type and length of the offset field. Most common is LE 16
- *          bits (that's why that is zero); others are there mostly to
- *          cover for bugs and weirdos.

- * UWB Multi-interface Controller support.

- * Copyright (C) 2007 Cambridge Silicon Radio Ltd.
- *
- * This file is released under the GPLv2
- *
- * UMC (UWB Multi-interface Controller) capabilities (e.g., radio
- * controller, host controller) are presented as devices on the "umc"
- * bus.
- *
- * The radio controller is not strictly a UMC capability but it's
- * useful to present it as such.
- *
- * References:
- *
- *   [WHCI] Wireless Host Controller Interface Specification for
- *          Certified Wireless Universal Serial Bus, revision 0.95.
- *
- * How this works is kind of convoluted but simple. The whci.ko driver
- * loads when WHCI devices are detected. These WHCI devices expose
- * many devices in the same PCI function (they couldn't have reused
- * functions, no), so for each PCI function that exposes these many
- * devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
- * with umc_device_create() and adds it to the bus with
- * umc_device_register().
- *
- * umc_device_register() calls device_register() which will push the
- * bus management code to load your UMC driver's somehting_probe()
- * that you have registered for that capability code.
- *
- * Now when the WHCI device is removed, whci_remove() will go over
- * each umc_dev assigned to each of the PCI function's capabilities
- * and through whci_del_cap() call umc_device_unregister() each
- * created umc_dev. Of course, if you are bound to the device, your
- * driver's something_remove() will be called.

- *
- *
- * EXECUTING DEBUGGING ACTIONS OR NOT
- *
- * The main thing this framework provides is decission power to take a
- * debug action (like printing a message) if the current debug level
- * allows it.
- *
- * The decission power is at two levels: at compile-time (what does
- * not make it is compiled out) and at run-time. The run-time
- * selection is done per-submodule (as they are declared by the user
- * of the framework).
- *
- * A call to d_test(L) (L being the target debug level) returns true
- * if the action should be taken because the current debug levels
- * allow it (both compile and run time).
- *
- * It follows that a call to d_test() that can be determined to be
- * always false at compile time will get the code depending on it
- * compiled out by optimization.
- *
- *
- * DEBUG LEVELS
- *
- * It is up to the caller to define how much a debugging level is.
- *
- * Convention sets 0 as "no debug" (so an action marked as debug level 0
- * will always be taken). The increasing debug levels are used for
- * increased verbosity.
- *
- *
- * USAGE
- *
- * Group the code in modules and submodules inside each module [which
- * in most cases maps to Linux modules and .c files that compose
- * those].
- *
- *
- * For each module, there is:
- *
- *  - a MODULENAME (single word, legal C identifier)
- *
- *  - a debug-levels.h header file that declares the list of
- *    submodules and that is included by all .c files that use
- *    the debugging tools. The file name can be anything.
- *
- *  - some (optional) .c code to manipulate the runtime debug levels
- *    through debugfs.
- *
- * The debug-levels.h file would look like:
- *
- *     #ifndef __debug_levels__h__
- *     #define __debug_levels__h__
- *
- *     #define D_MODULENAME modulename
- *     #define D_MASTER 10
- *
- *     #include <linux/wimax/debug.h>
- *
- *     enum d_module {
- *             D_SUBMODULE_DECLARE(submodule_1),
- *             D_SUBMODULE_DECLARE(submodule_2),
- *             ...
- *             D_SUBMODULE_DECLARE(submodule_N)
- *     };
- *
- *     #endif
- *
- * D_MASTER is the maximum compile-time debug level; any debug actions
- * above this will be out. D_MODULENAME is the module name (legal C
- * identifier), which has to be unique for each module (to avoid
- * namespace collisions during linkage). Note those #defines need to
- * be done before #including debug.h
- *
- * We declare N different submodules whose debug level can be
- * independently controlled during runtime.
- *
- * In a .c file of the module (and only in one of them), define the
- * following code:
- *
- *     struct d_level D_LEVEL[] = {
- *             D_SUBMODULE_DEFINE(submodule_1),
- *             D_SUBMODULE_DEFINE(submodule_2),
- *             ...
- *             D_SUBMODULE_DEFINE(submodule_N),
- *     };
- *     size_t D_LEVEL_SIZE = ARRAY_SIZE(D_LEVEL);
- *
- * Externs for d_level_MODULENAME and d_level_size_MODULENAME are used
- * and declared in this file using the D_LEVEL and D_LEVEL_SIZE macros
- * #defined also in this file.
- *
- * To manipulate from user space the levels, create a debugfs dentry
- * and then register each submodule with:
- *
- *     result = d_level_register_debugfs("PREFIX_", submodule_X, parent);
- *     if (result < 0)
- *            goto error;
- *
- * Where PREFIX_ is a name of your chosing. This will create debugfs
- * file with a single numeric value that can be use to tweak it. To
- * remove the entires, just use debugfs_remove_recursive() on 'parent'.
- *
- * NOTE: remember that even if this will show attached to some
- *     particular instance of a device, the settings are *global*.
- *
- *
- * On each submodule (for example, .c files), the debug infrastructure
- * should be included like this:
- *
- *     #define D_SUBMODULE submodule_x     // matches one in debug-levels.h
- *     #include "debug-levels.h"
- *
- * after #including all your include files.
- *
- *
- * Now you can use the d_*() macros below [d_test(), d_fnstart(),
- * d_fnend(), d_printf(), d_dump()].
- *
- * If their debug level is greater than D_MASTER, they will be
- * compiled out.
- *
- * If their debug level is lower or equal than D_MASTER but greater
- * than the current debug level of their submodule, they'll be
- * ignored.
- *
- * Otherwise, the action will be performed.

+  Introduction
+
+  zstd, short for Zstandard, is a fast lossless compression algorithm, targeting
+  real-time compression scenarios at zlib-level and better compression ratios.
+  The zstd compression library provides in-memory compression and decompression
+  functions.
+
+  The library supports regular compression levels from 1 up to ZSTD_maxCLevel(),
+  which is currently 22. Levels >= 20, labeled `--ultra`, should be used with
+  caution, as they require more memory. The library also offers negative
+  compression levels, which extend the range of speed vs. ratio preferences.
+  The lower the level, the faster the speed (at the cost of compression).
+
+  Compression can be done in:
+    - a single step (described as Simple API)
+    - a single step, reusing a context (described as Explicit context)
+    - unbounded multiple steps (described as Streaming compression)
+
+  The compression ratio achievable on small data can be highly improved using
+  a dictionary. Dictionary compression can be performed in:
+    - a single step (described as Simple dictionary API)
+    - a single step, reusing a dictionary (described as Bulk-processing
+      dictionary API)
+
+  Advanced experimental functions can be accessed using
+  `#define ZSTD_STATIC_LINKING_ONLY` before including zstd.h.
+
+  Advanced experimental APIs should never be used with a dynamically-linked
+  library. They are not "stable"; their definitions or signatures may change in
+  the future. Only static linking is allowed.

+*  Streaming compression - HowTo
+*
+*  A ZSTD_CStream object is required to track streaming operation.
+*  Use ZSTD_createCStream() and ZSTD_freeCStream() to create/release resources.
+*  ZSTD_CStream objects can be reused multiple times on consecutive compression operations.
+*  It is recommended to re-use ZSTD_CStream since it will play nicer with system's memory, by re-using already allocated memory.
+*
+*  For parallel execution, use one separate ZSTD_CStream per thread.
+*
+*  note : since v1.3.0, ZSTD_CStream and ZSTD_CCtx are the same thing.
+*
+*  Parameters are sticky : when starting a new compression on the same context,
+*  it will re-use the same sticky parameters as previous compression session.
+*  When in doubt, it's recommended to fully initialize the context before usage.
+*  Use ZSTD_CCtx_reset() to reset the context and ZSTD_CCtx_setParameter(),
+*  ZSTD_CCtx_setPledgedSrcSize(), or ZSTD_CCtx_loadDictionary() and friends to
+*  set more specific parameters, the pledged source size, or load a dictionary.
+*
+*  Use ZSTD_compressStream2() with ZSTD_e_continue as many times as necessary to
+*  consume input stream. The function will automatically update both `pos`
+*  fields within `input` and `output`.
+*  Note that the function may not consume the entire input, for example, because
+*  the output buffer is already full, in which case `input.pos < input.size`.
+*  The caller must check if input has been entirely consumed.
+*  If not, the caller must make some room to receive more compressed data,
+*  and then present again remaining input data.
+*  note: ZSTD_e_continue is guaranteed to make some forward progress when called,
+*        but doesn't guarantee maximal forward progress. This is especially relevant
+*        when compressing with multiple threads. The call won't block if it can
+*        consume some input, but if it can't it will wait for some, but not all,
+*        output to be flushed.
+* @return : provides a minimum amount of data remaining to be flushed from internal buffers
+*           or an error code, which can be tested using ZSTD_isError().
+*
+*  At any moment, it's possible to flush whatever data might remain stuck within internal buffer,
+*  using ZSTD_compressStream2() with ZSTD_e_flush. `output->pos` will be updated.
+*  Note that, if `output->size` is too small, a single invocation with ZSTD_e_flush might not be enough (return code > 0).
+*  In which case, make some room to receive more compressed data, and call again ZSTD_compressStream2() with ZSTD_e_flush.
+*  You must continue calling ZSTD_compressStream2() with ZSTD_e_flush until it returns 0, at which point you can change the
+*  operation.
+*  note: ZSTD_e_flush will flush as much output as possible, meaning when compressing with multiple threads, it will
+*        block until the flush is complete or the output buffer is full.
+*  @return : 0 if internal buffers are entirely flushed,
+*            >0 if some data still present within internal buffer (the value is minimal estimation of remaining size),
+*            or an error code, which can be tested using ZSTD_isError().
+*
+*  Calling ZSTD_compressStream2() with ZSTD_e_end instructs to finish a frame.
+*  It will perform a flush and write frame epilogue.
+*  The epilogue is required for decoders to consider a frame completed.
+*  flush operation is the same, and follows same rules as calling ZSTD_compressStream2() with ZSTD_e_flush.
+*  You must continue calling ZSTD_compressStream2() with ZSTD_e_end until it returns 0, at which point you are free to
+*  start a new frame.
+*  note: ZSTD_e_end will flush as much output as possible, meaning when compressing with multiple threads, it will
+*        block until the flush is complete or the output buffer is full.
+*  @return : 0 if frame fully completed and fully flushed,

+     *   compression. For small compressions (< 8 KB), that copy can dominate
+     *   the cost of the compression.
+     *
+     * - The CDict's tables can be used in-place. In this model, compression is
+     *   slower per input byte, because the compressor has to search two sets of
+     *   tables. However, this model incurs no start-up cost (as long as the
+     *   working context's tables can be reused). For small inputs, this can be
+     *   faster than copying the CDict's tables.
+     *
+     * - The CDict's tables are not used at all, and instead we use the working
+     *   context alone to reload the dictionary and use params based on the source
+     *   size. See ZSTD_compress_insertDictionary() and ZSTD_compress_usingDict().
+     *   This method is effective when the dictionary sizes are very small relative
+     *   to the input size, and the input size is fairly large to begin with.

+ * structure" can be used. This feature is still rough around the edges, be
+ * prepared for surprising behavior!
+ *
+ * How to use it:
+ *
+ * When using a CDict, whether to use this feature or not is controlled at
+ * CDict creation, and it must be set in a CCtxParams set passed into that
+ * construction (via ZSTD_createCDict_advanced2()). A compression will then
+ * use the feature or not based on how the CDict was constructed; the value of
+ * this param, set in the CCtx, will have no effect.
+ *
+ * However, when a dictionary buffer is passed into a CCtx, such as via
+ * ZSTD_CCtx_loadDictionary(), this param can be set on the CCtx to control
+ * whether the CDict that is created internally can use the feature or not.
+ *
+ * What it does:
+ *
+ * Normally, the internal data structures of the CDict are analogous to what
+ * would be stored in a CCtx after compressing the contents of a dictionary.
+ * To an approximation, a compression using a dictionary can then use those
+ * data structures to simply continue what is effectively a streaming
+ * compression where the simulated compression of the dictionary left off.
+ * Which is to say, the search structures in the CDict are normally the same
+ * format as in the CCtx.
+ *
+ * It is possible to do better, since the CDict is not like a CCtx: the search
+ * structures are written once during CDict creation, and then are only read
+ * after that, while the search structures in the CCtx are both read and
+ * written as the compression goes along. This means we can choose a search
+ * structure for the dictionary that is read-optimized.
+ *
+ * This feature enables the use of that different structure.
+ *
+ * Note that some of the members of the ZSTD_compressionParameters struct have
+ * different semantics and constraints in the dedicated search structure. It is
+ * highly recommended that you simply set a compression level in the CCtxParams
+ * you pass into the CDict creation call, and avoid messing with the cParams
+ * directly.
+ *
+ * Effects:
+ *
+ * This will only have any effect when the selected ZSTD_strategy
+ * implementation supports this feature. Currently, that's limited to
+ * ZSTD_greedy, ZSTD_lazy, and ZSTD_lazy2.
+ *
+ * Note that this means that the CDict tables can no longer be copied into the
+ * CCtx, so the dict attachment mode ZSTD_dictForceCopy will no longer be
+ * usable. The dictionary can only be attached or reloaded.
+ *
+ * In general, you should expect compression to be faster--sometimes very much
+ * so--and CDict creation to be slightly slower. Eventually, we will probably
+ * make this mode the default.

+  Buffer-less streaming decompression (synchronous mode)
+
+  A ZSTD_DCtx object is required to track streaming operations.
+  Use ZSTD_createDCtx() / ZSTD_freeDCtx() to manage it.
+  A ZSTD_DCtx object can be re-used multiple times.
+
+  First typical operation is to retrieve frame parameters, using ZSTD_getFrameHeader().
+  Frame header is extracted from the beginning of compressed frame, so providing only the frame's beginning is enough.
+  Data fragment must be large enough to ensure successful decoding.
+ `ZSTD_frameHeaderSize_max` bytes is guaranteed to always be large enough.
+  @result : 0 : successful decoding, the `ZSTD_frameHeader` structure is correctly filled.
+           >0 : `srcSize` is too small, please provide at least @result bytes on next attempt.
+           errorCode, which can be tested using ZSTD_isError().
+
+  It fills a ZSTD_frameHeader structure with important information to correctly decode the frame,
+  such as the dictionary ID, content size, or maximum back-reference distance (`windowSize`).
+  Note that these values could be wrong, either because of data corruption, or because a 3rd party deliberately spoofs false information.
+  As a consequence, check that values remain within valid application range.
+  For example, do not allocate memory blindly, check that `windowSize` is within expectation.
+  Each application can set its own limits, depending on local restrictions.
+  For extended interoperability, it is recommended to support `windowSize` of at least 8 MB.
+
+  ZSTD_decompressContinue() needs previous data blocks during decompression, up to `windowSize` bytes.
+  ZSTD_decompressContinue() is very sensitive to contiguity,
+  if 2 blocks don't follow each other, make sure that either the compressor breaks contiguity at the same place,
+  or that previous contiguous segment is large enough to properly handle maximum back-reference distance.
+  There are multiple ways to guarantee this condition.
+
+  The most memory efficient way is to use a round buffer of sufficient size.
+  Sufficient size is determined by invoking ZSTD_decodingBufferSize_min(),
+  which can @return an error code if required value is too large for current system (in 32-bits mode).
+  In a round buffer methodology, ZSTD_decompressContinue() decompresses each block next to previous one,
+  up to the moment there is not enough room left in the buffer to guarantee decoding another full block,
+  which maximum size is provided in `ZSTD_frameHeader` structure, field `blockSizeMax`.
+  At which point, decoding can resume from the beginning of the buffer.
+  Note that already decoded data stored in the buffer should be flushed before being overwritten.
+
+  There are alternatives possible, for example using two or more buffers of size `windowSize` each, though they consume more memory.
+
+  Finally, if you control the compression process, you can also ignore all buffer size rules,
+  as long as the encoder and decoder progress in "lock-step",
+  aka use exactly the same buffer sizes, break contiguity at the same place, etc.
+
+  Once buffers are setup, start decompression, with ZSTD_decompressBegin().
+  If decompression requires a dictionary, use ZSTD_decompressBegin_usingDict() or ZSTD_decompressBegin_usingDDict().
+
+  Then use ZSTD_nextSrcSizeToDecompress() and ZSTD_decompressContinue() alternatively.
+  ZSTD_nextSrcSizeToDecompress() tells how many bytes to provide as 'srcSize' to ZSTD_decompressContinue().
+  ZSTD_decompressContinue() requires this _exact_ amount of bytes, or it will fail.

+ @result of ZSTD_decompressContinue() is the number of bytes regenerated within 'dst' (necessarily <= dstCapacity).
+  It can be zero : it just means ZSTD_decompressContinue() has decoded some metadata item.
+  It can also be an error code, which can be tested with ZSTD_isError().
+
+  A frame is fully decoded when ZSTD_nextSrcSizeToDecompress() returns zero.
+  Context can then be reset to start a new decompression.
+
+  Note : it's possible to know if next input to present is a header or a block, using ZSTD_nextInputType().
+  This information is not required to properly decode a frame.
+
+  == Special case : skippable frames ==
+
+  Skippable frames allow integration of user-defined data into a flow of concatenated frames.
+  Skippable frames will be ignored (skipped) by decompressor.
+  The format of skippable frames is as follows :
+  a) Skippable frame ID - 4 Bytes, Little endian format, any value from 0x184D2A50 to 0x184D2A5F
+  b) Frame Size - 4 Bytes, Little endian format, unsigned 32-bits
+  c) Frame Content - any content (User Data) of length equal to Frame Size
+  For skippable frames ZSTD_getFrameHeader() returns zfhPtr->frameType==ZSTD_skippableFrame.
+  For skippable frames ZSTD_decompressContinue() always returns 0 : it only skips the content.

+    Block functions produce and decode raw zstd blocks, without frame metadata.
+    Frame metadata cost is typically ~12 bytes, which can be non-negligible for very small blocks (< 100 bytes).
+    But users will have to take in charge needed metadata to regenerate data, such as compressed and content sizes.
+
+    A few rules to respect :
+    - Compressing and decompressing require a context structure
+      + Use ZSTD_createCCtx() and ZSTD_createDCtx()
+    - It is necessary to init context before starting
+      + compression : any ZSTD_compressBegin*() variant, including with dictionary
+      + decompression : any ZSTD_decompressBegin*() variant, including with dictionary
+      + copyCCtx() and copyDCtx() can be used too
+    - Block size is limited, it must be <= ZSTD_getBlockSize() <= ZSTD_BLOCKSIZE_MAX == 128 KB
+      + If input is larger than a block size, it's necessary to split input data into multiple blocks
+      + For inputs larger than a single block, consider using regular ZSTD_compress() instead.
+        Frame metadata is not that costly, and quickly becomes negligible as source size grows larger than a block.
+    - When a block is considered not compressible enough, ZSTD_compressBlock() result will be 0 (zero) !
+      ===> In which case, nothing is produced into `dst` !
+      + User __must__ test for such outcome and deal directly with uncompressed data
+      + A block cannot be declared incompressible if ZSTD_compressBlock() return value was != 0.
+        Doing so would mess up with statistics history, leading to potential data corruption.
+      + ZSTD_decompressBlock() _doesn't accept uncompressed data as input_ !!
+      + In case of multiple successive blocks, should some of them be uncompressed,
+        decoder must be informed of their existence in order to follow proper history.
+        Use ZSTD_insertBlock() for such a case.

-/* Note that the cx25840 driver requires that the bridge driver calls the
-   v4l2_subdev's init operation in order to load the driver's firmware.
-   Without this the audio standard detection will fail and you will
-   only get mono.
-
-   Since loading the firmware is often problematic when the driver is
-   compiled into the kernel I recommend postponing calling this function
-   until the first open of the video device. Another reason for
-   postponing it is that loading this firmware takes a long time (seconds)
-   due to the slow i2c bus speed. So it will speed up the boot process if
-   you can avoid loading the fw as long as the video device isn't used. */

+ *
+ * This function callback prototype, provided by the client of the demux API,
+ * is called from the demux code. The function is only called when filtering
+ * on a TS feed has been enabled using the start_filtering\(\) function at
+ * the &dmx_demux.
+ * Any TS packets that match the filter settings are copied to a circular
+ * buffer. The filtered TS packets are delivered to the client using this
+ * callback function.
+ * It is expected that the @buffer1 and @buffer2 callback parameters point to
+ * addresses within the circular buffer, but other implementations are also
+ * possible. Note that the called party should not try to free the memory
+ * the @buffer1 and @buffer2 parameters point to.
+ *
+ * When this function is called, the @buffer1 parameter typically points to
+ * the start of the first undelivered TS packet within a circular buffer.
+ * The @buffer2 buffer parameter is normally NULL, except when the received
+ * TS packets have crossed the last address of the circular buffer and
+ * "wrapped" to the beginning of the buffer. In the latter case the @buffer1
+ * parameter would contain an address within the circular buffer, while the
+ * @buffer2 parameter would contain the first address of the circular buffer.
+ * The number of bytes delivered with this function (i.e. @buffer1_length +
+ * @buffer2_length) is usually equal to the value of callback_length parameter
+ * given in the set() function, with one exception: if a timeout occurs before
+ * receiving callback_length bytes of TS data, any undelivered packets are
+ * immediately delivered to the client by calling this function. The timeout
+ * duration is controlled by the set() function in the TS Feed API.
+ *
+ * If a TS packet is received with errors that could not be fixed by the
+ * TS-level forward error correction (FEC), the Transport_error_indicator
+ * flag of the TS packet header should be set. The TS packet should not be
+ * discarded, as the error can possibly be corrected by a higher layer
+ * protocol. If the called party is slow in processing the callback, it
+ * is possible that the circular buffer eventually fills up. If this happens,
+ * the demux driver should discard any TS packets received while the buffer
+ * is full and return -EOVERFLOW.
+ *
+ * The type of data returned to the callback can be selected by the
+ * &dmx_ts_feed.@set function. The type parameter decides if the raw
+ * TS packet (TS_PACKET) or just the payload (TS_PACKET|TS_PAYLOAD_ONLY)
+ * should be returned. If additionally the TS_DECODER bit is set the stream
+ * will also be sent to the hardware MPEG decoder.

+ * function should be called with the corresponding error type set in the

+ * implementation should maintain a circular buffer for received sections.

+ * If there is no room in the circular buffer when a new section is received,

+ *	function implementation should increment the demux usage count when
+ *	@open is called and decrement it when @close is called.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EUSERS, if maximum usage count was reached;
+ *	-EINVAL, on bad parameter.
+ *
+ * @close: This function reserves the demux for use by the caller and, if

+ *	the function @close should be called. It should be possible for
+ *	multiple clients to access the demux at the same time. Thus, the

+ *	It returns:
+ *	0 on success;
+ *	-ENODEV, if demux was not in use (e. g. no users);
+ *	-EINVAL, on bad parameter.
+ *
+ * @write: This function provides the demux driver with a memory buffer
+ *	containing TS packets. Instead of receiving TS packets from the DVB
+ *	front-end, the demux driver software will read packets from memory.
+ *	Any clients of this demux with active TS, PES or Section filters will
+ *	receive filtered data via the Demux callback API (see 0). The function
+ *	returns when all the data in the buffer has been consumed by the demux.
+ *	Demux hardware typically cannot read TS from memory. If this is the
+ *	case, memory-based filtering has to be implemented entirely in software.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @buf function parameter contains a pointer to the TS data in
+ *	kernel-space memory.
+ *	The @count function parameter contains the length of the TS data.
+ *	It returns:
+ *	0 on success;
+ *	-ERESTARTSYS, if mutex lock was interrupted;
+ *	-EINTR, if a signal handling is pending;
+ *	-ENODEV, if demux was removed;
+ *	-EINVAL, on bad parameter.
+ *
+ * @allocate_ts_feed: Allocates a new TS feed, which is used to filter the TS
+ *	packets carrying a certain PID. The TS feed normally corresponds to a
+ *	hardware PID filter on the demux chip.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	The @callback function parameter contains a pointer to the callback
+ *	function for passing received TS packet.
+ *	It returns:
+ *	0 on success;
+ *	-ERESTARTSYS, if mutex lock was interrupted;
+ *	-EBUSY, if no more TS feeds is available;
+ *	-EINVAL, on bad parameter.
+ *
+ * @release_ts_feed: Releases the resources allocated with @allocate_ts_feed.
+ *	Any filtering in progress on the TS feed should be stopped before
+ *	calling this function.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EINVAL on bad parameter.
+ *
+ * @allocate_section_feed: Allocates a new section feed, i.e. a demux resource
+ *	for filtering and receiving sections. On platforms with hardware
+ *	support for section filtering, a section feed is directly mapped to
+ *	the demux HW. On other platforms, TS packets are first PID filtered in
+ *	hardware and a hardware section filter then emulated in software. The
+ *	caller obtains an API pointer of type dmx_section_feed_t as an out
+ *	parameter. Using this API the caller can set filtering parameters and
+ *	start receiving sections.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	The @callback function parameter contains a pointer to the callback
+ *	function for passing received TS packet.
+ *	It returns:
+ *	0 on success;
+ *	-EBUSY, if no more TS feeds is available;
+ *	-EINVAL, on bad parameter.
+ *
+ * @release_section_feed: Releases the resources allocated with
+ *	@allocate_section_feed, including allocated filters. Any filtering in
+ *	progress on the section feed should be stopped before calling this
+ *	function.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EINVAL, on bad parameter.
+ *
+ * @add_frontend: Registers a connectivity between a demux and a front-end,
+ *	i.e., indicates that the demux can be connected via a call to
+ *	@connect_frontend to use the given front-end as a TS source. The
+ *	client of this function has to allocate dynamic or static memory for
+ *	the frontend structure and initialize its fields before calling this
+ *	function. This function is normally called during the driver
+ *	initialization. The caller must not free the memory of the frontend
+ *	struct before successfully calling @remove_frontend.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @frontend function parameter contains a pointer to the front-end
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EINVAL, on bad parameter.
+ *
+ * @remove_frontend: Indicates that the given front-end, registered by a call
+ *	to @add_frontend, can no longer be connected as a TS source by this
+ *	demux. The function should be called when a front-end driver or a demux
+ *	driver is removed from the system. If the front-end is in use, the
+ *	function fails with the return value of -EBUSY. After successfully
+ *	calling this function, the caller can free the memory of the frontend
+ *	struct if it was dynamically allocated before the @add_frontend
+ *	operation.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @frontend function parameter contains a pointer to the front-end
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-ENODEV, if the front-end was not found,
+ *	-EINVAL, on bad parameter.
+ *
+ * @get_frontends: Provides the APIs of the front-ends that have been
+ *	registered for this demux. Any of the front-ends obtained with this
+ *	call can be used as a parameter for @connect_frontend. The include
+ *	file demux.h contains the macro DMX_FE_ENTRY() for converting an
+ *	element of the generic type struct &list_head * to the type
+ *	struct &dmx_frontend *. The caller must not free the memory of any of
+ *	the elements obtained via this function call.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	It returns a struct list_head pointer to the list of front-end
+ *	interfaces, or NULL in the case of an empty list.
+ *
+ * @connect_frontend: Connects the TS output of the front-end to the input of
+ *	the demux. A demux can only be connected to a front-end registered to
+ *	the demux with the function @add_frontend. It may or may not be
+ *	possible to connect multiple demuxes to the same front-end, depending
+ *	on the capabilities of the HW platform. When not used, the front-end
+ *	should be released by calling @disconnect_frontend.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @frontend function parameter contains a pointer to the front-end
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EINVAL, on bad parameter.
+ *
+ * @disconnect_frontend: Disconnects the demux and a front-end previously
+ *	connected by a @connect_frontend call.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	It returns:
+ *	0 on success;
+ *	-EINVAL on bad parameter.
+ *
+ * @get_pes_pids: Get the PIDs for DMX_PES_AUDIO0, DMX_PES_VIDEO0,
+ *	DMX_PES_TELETEXT0, DMX_PES_SUBTITLE0 and DMX_PES_PCR0.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @pids function parameter contains an array with five u16 elements
+ *	where the PIDs will be stored.
+ *	It returns:

+ * Note that the cx25840 driver requires that the bridge driver calls the

+ * Without this the audio standard detection will fail and you will
+ * only get mono.
+ * Alternatively, you can call the reset operation (this can be done
+ * multiple times if needed, each invocation will fully reinitialize
+ * the device).
+ *
+ * Since loading the firmware is often problematic when the driver is
+ * compiled into the kernel I recommend postponing calling this function
+ * until the first open of the video device. Another reason for
+ * postponing it is that loading this firmware takes a long time (seconds)
+ * due to the slow i2c bus speed. So it will speed up the boot process if
+ * you can avoid loading the fw as long as the video device isn't used.

+/* msp3400 routing
+   ===============
+
+   The msp3400 has a complicated routing scheme with many possible
+   combinations. The details are all in the datasheets but I will try
+   to give a short description here.
+
+   Inputs
+   ======
+
+   There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+   to select which tuner input to use and which SCART input to use. The
+   selected tuner input, the selected SCART input and all I2S inputs go to
+   the DSP (the tuner input first goes through the demodulator).
+
+   The DSP handles things like volume, bass/treble, balance, and some chips
+   have support for surround sound. It has several outputs: MAIN, AUX, I2S
+   and SCART1/2. Each output can select which DSP input to use. So the MAIN
+   output can select the tuner input while at the same time the SCART1 output
+   uses the I2S input.
+
+   Outputs
+   =======
+
+   Most DSP outputs are also the outputs of the msp3400. However, the SCART
+   outputs of the msp3400 can select which input to use: either the SCART1 or
+   SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+   bypassing the DSP.
+
+   Summary
+   =======
+
+   So to specify a complete routing scheme for the msp3400 you will have to
+   specify in the 'input' arg of the s_routing function:
+
+   1) which tuner input to use
+   2) which SCART input to use
+   3) which DSP input to use for each DSP output
+
+   And in the 'output' arg of the s_routing function you specify:
+
+   1) which SCART input to use for each SCART output
+
+   Depending on how the msp is wired to the other components you can
+   ignore or mute certain inputs or outputs.
+
+   Also, depending on the msp version only a subset of the inputs or
+   outputs may be present. At the end of this header some tables are
+   added containing a list of what is available for each msp version.
+ */
+
+/* Inputs to the DSP unit: two independent selections have to be made:
+   1) the tuner (SIF) input
+   2) the SCART input
+   Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
+   input, bits 4-7 are reserved.

+/* The msp has up to 5 DSP outputs, each output can independently select
+   a DSP input.
+
+   The DSP outputs are: loudspeaker output (aka MAIN), headphones output
+   (aka AUX), SCART1 DA output, SCART2 DA output and an I2S output.
+   There also is a quasi-peak detector output, but that is not used by
+   this driver and is set to the same input as the loudspeaker output.
+   Not all outputs are supported by all msp models. Setting the input
+   of an unsupported output will be ignored by the driver.
+
+   There are up to 16 DSP inputs to choose from, so each output is
+   assigned 4 bits.
+
+   Note: the 44x8G can mix two inputs and feed the result back to the
+   DSP. This is currently not implemented. Also not implemented is the
+   multi-channel capable I2S3 input of the 44x0G. If someone can demonstrate

-/* msp3400 routing
-   ===============
-
-   The msp3400 has a complicated routing scheme with many possible
-   combinations. The details are all in the datasheets but I will try
-   to give a short description here.
-
-   Inputs
-   ======
-
-   There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
-   to select which tuner input to use and which SCART input to use. The
-   selected tuner input, the selected SCART input and all I2S inputs go to
-   the DSP (the tuner input first goes through the demodulator).
-
-   The DSP handles things like volume, bass/treble, balance, and some chips
-   have support for surround sound. It has several outputs: MAIN, AUX, I2S
-   and SCART1/2. Each output can select which DSP input to use. So the MAIN
-   output can select the tuner input while at the same time the SCART1 output
-   uses the I2S input.
-
-   Outputs
-   =======
-
-   Most DSP outputs are also the outputs of the msp3400. However, the SCART
-   outputs of the msp3400 can select which input to use: either the SCART1 or
-   SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
-   bypassing the DSP.
-
-   Summary
-   =======
-
-   So to specify a complete routing scheme for the msp3400 you will have to
-   specify in the 'input' arg of the s_routing function:
-
-   1) which tuner input to use
-   2) which SCART input to use
-   3) which DSP input to use for each DSP output
-
-   And in the 'output' arg of the s_routing function you specify:
-
-   1) which SCART input to use for each SCART output
-
-   Depending on how the msp is wired to the other components you can
-   ignore or mute certain inputs or outputs.
-
-   Also, depending on the msp version only a subset of the inputs or
-   outputs may be present. At the end of this header some tables are
-   added containing a list of what is available for each msp version.
- */
-
-/* Inputs to the DSP unit: two independent selections have to be made:
-   1) the tuner (SIF) input
-   2) the SCART input
-   Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
-   input, bits 4-7 are reserved.

-

-   There also is a quasi-peak detector output, but that is not used by
-   this driver and is set to the same input as the loudspeaker output.
-   Not all outputs are supported by all msp models. Setting the input
-   of an unsupported output will be ignored by the driver.
-
-   There are up to 16 DSP inputs to choose from, so each output is
