*
* Memory Structure:
*
- * To support the needs of the most prominent user of AEAD ciphers, namely
- * IPSEC, the AEAD ciphers have a special memory layout the caller must adhere
- * to.
- *
- * The scatter list pointing to the input data must contain:
- *
- * * for RFC4106 ciphers, the concatenation of
- * associated authentication data || IV || plaintext or ciphertext. Note, the
- * same IV (buffer) is also set with the aead_request_set_crypt call. Note,
- * the API call of aead_request_set_ad must provide the length of the AAD and
- * the IV. The API call of aead_request_set_crypt only points to the size of
- * the input plaintext or ciphertext.
- *
- * * for "normal" AEAD ciphers, the concatenation of
- * associated authentication data || plaintext or ciphertext.
- *
- * It is important to note that if multiple scatter gather list entries form
- * the input data mentioned above, the first entry must not point to a NULL
- * buffer. If there is any potential where the AAD buffer can be NULL, the
- * calling code must contain a precaution to ensure that this does not result
- * in the first scatter gather list entry pointing to a NULL buffer.
+ * 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).
+ *
+ * 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.

+ * AWB == 1: autowhitebalance is on, the do_white_balance button is inactive,
+ * 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
+ * checker card) and the userspace can read again the new values.
+ *
+ * With this feature, the userspace can save the coefficients and reinstall them
+ * for example after reboot or reprobing the driver.

+ * inserted.
+ * Must not be set for devices which are removed entirely when the
+ * media is removed.
+ *
+ * ``GENHD_FL_CD`` (0x0008): the block device is a CD-ROM-style
+ * device.
+ * Affects responses to the ``CDROM_GET_CAPABILITY`` ioctl.
+ *
+ * ``GENHD_FL_UP`` (0x0010): indicates that the block device is "up",
+ * with a similar meaning to network interfaces.
+ *
+ * ``GENHD_FL_SUPPRESS_PARTITION_INFO`` (0x0020): don't include
+ * partition information in ``/proc/partitions`` or in the output of
+ * printk_all_partitions().
+ * Used for the null block device and some MMC devices.
+ *
+ * ``GENHD_FL_EXT_DEVT`` (0x0040): the driver supports extended
+ * dynamic ``dev_t``, i.e. it wants extended device numbers
+ * (``BLOCK_EXT_MAJOR``).
+ * This affects the maximum number of partitions.
+ *
+ * ``GENHD_FL_NATIVE_CAPACITY`` (0x0080): based on information in the
+ * partition table, the device's capacity has been extended to its
+ * native capacity; i.e. the device has hidden capacity used by one
+ * of the partitions (this is a flag used so that native capacity is
+ * only ever unlocked once).
+ *
+ * ``GENHD_FL_BLOCK_EVENTS_ON_EXCL_WRITE`` (0x0100): event polling is
+ * blocked whenever a writer holds an exclusive lock.
+ *
+ * ``GENHD_FL_NO_PART_SCAN`` (0x0200): partition scanning is disabled.
+ * Used for loop devices in their default settings and some MMC
+ * devices.
+ *
+ * ``GENHD_FL_HIDDEN`` (0x0400): the block device is hidden; it
+ * doesn't produce events, doesn't appear in sysfs, and doesn't have
+ * an associated ``bdev``.
+ * Implies ``GENHD_FL_SUPPRESS_PARTITION_INFO`` and
+ * ``GENHD_FL_NO_PART_SCAN``.
+ * Used for multipath devices.

- * Heterogeneous Memory Management (HMM)
- *
- * See Documentation/vm/hmm.rst for reasons and overview of what HMM is and it
- * is for. Here we focus on the HMM API description, with some explanation of
- * the underlying implementation.
- *
- * Short description: HMM provides a set of helpers to share a virtual address
- * space between CPU and a device, so that the device can access any valid
- * address of the process (while still obeying memory protection). HMM also
- * provides helpers to migrate process memory to device memory, and back. Each
- * set of functionality (address space mirroring, and migration to and from
- * device memory) can be used independently of the other.
- *
- *
- * HMM address space mirroring API:
- *
- * Use HMM address space mirroring if you want to mirror a range of the CPU
- * page tables of a process into a device page table. Here, "mirror" means "keep
- * synchronized". Prerequisites: the device must provide the ability to write-
- * protect its page tables (at PAGE_SIZE granularity), and must be able to
- * recover from the resulting potential page faults.
- *
- * HMM guarantees that at any point in time, a given virtual address points to
- * either the same memory in both CPU and device page tables (that is: CPU and
- * device page tables each point to the same pages), or that one page table (CPU
- * or device) points to no entry, while the other still points to the old page
- * for the address. The latter case happens when the CPU page table update
- * happens first, and then the update is mirrored over to the device page table.
- * This does not cause any issue, because the CPU page table cannot start
- * pointing to a new page until the device page table is invalidated.
- *
- * HMM uses mmu_notifiers to monitor the CPU page tables, and forwards any
- * updates to each device driver that has registered a mirror. It also provides
- * some API calls to help with taking a snapshot of the CPU page table, and to
- * synchronize with any updates that might happen concurrently.
*
- *
- * HMM migration to and from device memory:
- *
- * HMM provides a set of helpers to hotplug device memory as ZONE_DEVICE, with
- * a new MEMORY_DEVICE_PRIVATE type. This provides a struct page for each page
- * of the device memory, and allows the device driver to manage its memory
- * using those struct pages. Having struct pages for device memory makes
- * migration easier. Because that memory is not addressable by the CPU it must
- * never be pinned to the device; in other words, any CPU page fault can always
- * cause the device memory to be migrated (copied/moved) back to regular memory.
- *
- * A new migrate helper (migrate_vma()) has been added (see mm/migrate.c) that
- * allows use of a device DMA engine to perform the copy operation between
- * regular system memory and device memory.
+ * See Documentation/vm/hmm.rst for reasons and overview of what HMM is.
