    This patch adds the Kernel support for the caam-keygen user-space
    application. It has two IOCTL calls for key and blob generation and
    import a black key from a blob.

    This support is included in CRYPTO_DEV_FSL_CAAM_TK_API (tagged key
    support).

    Pull documentation updates from Mauro Carvalho Chehab:
    "A series of patches addressing warnings produced by make htmldocs.
    This includes:

    - kernel-doc markup fixes

    - ReST fixes

    - Updates at the build system in order to support newer versions of
    the docs build toolchain (Sphinx)

    After this series, the number of html build warnings should reduce
    significantly, and building with Sphinx 3.1 or later should now be
    supported (although it is still recommended to use Sphinx 2.4.4).

    As agreed with Jon, I should be sending you a late pull request by the
    end of the merge window addressing remaining issues with docs build,
    as there are a number of warning fixes that depends on pull requests
    that should be happening along the merge window.

    The end goal is to have a clean htmldocs build on Kernel 5.10.

    PS. It should be noticed that Sphinx 3.0 is not currently supported,
    as it lacks support for C domain namespaces. Such feature, needed in
    order to document uAPI system calls with Sphinx 3.x, was added only on
    Sphinx 3.1"

    - Continued SVM enablement, where page-table is shared with CPU

    - Groundwork to support integrated SMMU with Adreno GPU

    - Allow disabling of MSI-based polling on the kernel command-line

    - Minor driver fixes and cleanups (octal permissions, error
    messages, ...)

    - Secure Nested Paging Support for AMD IOMMU. The IOMMU will fault when
    a device tries DMA on memory owned by a guest. This needs new
    fault-types as well as a rewrite of the IOMMU memory semaphore for
    command completions.

    - Allow broken Intel IOMMUs (wrong address widths reported) to still be
    used for interrupt remapping.

    - IOMMU UAPI updates for supporting vSVA, where the IOMMU can access
    address spaces of processes running in a VM.

    - Support for the MT8167 IOMMU in the Mediatek IOMMU driver.

    - Device-tree updates for the Renesas driver to support r8a7742.

    IOMMU UAPI is newly introduced to support communications between guest
    virtual IOMMU and host IOMMU. There has been lots of discussions on how
    it should work with VFIO UAPI and userspace in general.

    This document is intended to clarify the UAPI design and usage. The
    mechanics of how future extensions should be achieved are also covered
    in this documentation.

    Using struct|enum :c:`type` here sounds a bad idea, as it may be
    documenting data types that were already removed. Also, it makes
    the file harder to read.

    As automarkup.py should be able to handle those cases, let's
    just get rid of the markup.

    While not required by automarkup, in order to make easier for
    grep, both type and names are now at the same line.

    There are several places there where struct was used twice,
    on multiple lines, like:

    struct
    struct ``v4l2_zoomcap``

    That's probably done during the DocBook to ReSt conversion.

    Probably the cases where "struct struct" were at the same line
    was addressed back then, but the multi-line cases are still
    there.

    Get rid of them.

    Sphinx 3.x is pedantic with glossary entries:

    While it works with case-insensitive entires, it complains.

    Let's fix it, in order to cleanup the warnings. Also, I won't
    doubt that a later change on Sphinx will end breaking support
    for it.

  • 62aacfa9b   media: v4l2: extend the CSC API to subdevice. ... Browse Code »

    This patch extends the CSC API in video devices to be supported
    also on sub-devices. The flag V4L2_MBUS_FRAMEFMT_SET_CSC set by
    the application when calling VIDIOC_SUBDEV_S_FMT ioctl.
    The flags:

    V4L2_SUBDEV_MBUS_CODE_CSC_COLORSPACE,
    V4L2_SUBDEV_MBUS_CODE_CSC_XFER_FUNC,
    V4L2_SUBDEV_MBUS_CODE_CSC_YCBCR_ENC/V4L2_SUBDEV_MBUS_CODE_CSC_HSV_ENC
    V4L2_SUBDEV_MBUS_CODE_CSC_QUANTIZATION

    are set by the driver in the VIDIOC_SUBDEV_ENUM_MBUS_CODE ioctl.

    New 'flags' fields were added to the structs
    v4l2_subdev_mbus_code_enum, v4l2_mbus_framefmt which are borrowed
    from the 'reserved' field

    The patch also replaces the 'ycbcr_enc' field in
    'struct v4l2_mbus_framefmt' with a union that includes 'hsv_enc'

  • b38c73ca1   media: v4l2: add support for colorspace conversion API (CSC) for video capture ... Browse Code »

    For video capture it is the driver that reports the colorspace,
    transfer function, Y'CbCr/HSV encoding and quantization range
    used by the video, and there is no way to request something
    different, even though many HDTV receivers have some sort of
    colorspace conversion capabilities.

    For output video this feature already exists since the application
    specifies this information for the video format it will send out, and
    the transmitter will enable any available CSC if a format conversion has
    to be performed in order to match the capabilities of the sink.

    For video capture we propose adding new v4l2_pix_format flag:
    V4L2_PIX_FMT_FLAG_SET_CSC. The flag is set by the application,
    the driver will interpret the colorspace, xfer_func, ycbcr_enc/hsv_enc
    and quantization fields as the requested colorspace information and will
    attempt to do the conversion it supports.

    Drivers set the flags
    V4L2_FMT_FLAG_CSC_COLORSPACE,
    V4L2_FMT_FLAG_CSC_XFER_FUNC,
    V4L2_FMT_FLAG_CSC_YCBCR_ENC/V4L2_FMT_FLAG_CSC_HSV_ENC,
    V4L2_FMT_FLAG_CSC_QUANTIZATION,
    in the flags field of the struct v4l2_fmtdesc during enumeration to
    indicate that they support colorspace conversion for the respective field.

    Drivers do not have to actually look at the flags. If the flags are not
    set, then the fields 'colorspace', 'xfer_func', 'ycbcr_enc/hsv_enc',
    and 'quantization' are set to the default values by the core, i.e. just
    pass on the received format without conversion.

  • 15b760c37   nitro_enclaves: Add ioctl interface definition ... Browse Code »

    The Nitro Enclaves driver handles the enclave lifetime management. This
    includes enclave creation, termination and setting up its resources such
    as memory and CPU.

    An enclave runs alongside the VM that spawned it. It is abstracted as a
    process running in the VM that launched it. The process interacts with
    the NE driver, that exposes an ioctl interface for creating an enclave
    and setting up its resources.

    Changelog

    v9 -> v10

    * Update commit message to include the changelog before the SoB tag(s).

    v8 -> v9

    * No changes.

    v7 -> v8

    * Add NE custom error codes for user space memory regions not backed by
    pages multiple of 2 MiB, invalid flags and enclave CID.
    * Add max flag value for enclave image load info.

    v6 -> v7

    * Clarify in the ioctls documentation that the return value is -1 and
    errno is set on failure.
    * Update the error code value for NE_ERR_INVALID_MEM_REGION_SIZE as it
    gets in user space as value 25 (ENOTTY) instead of 515. Update the
    NE custom error codes values range to not be the same as the ones
    defined in include/linux/errno.h, although these are not propagated
    to user space.

    v5 -> v6

    * Fix typo in the description about the NE CPU pool.
    * Update documentation to kernel-doc format.
    * Remove the ioctl to query API version.

    v4 -> v5

    * Add more details about the ioctl calls usage e.g. error codes, file
    descriptors used.
    * Update the ioctl to set an enclave vCPU to not return a file
    descriptor.
    * Add specific NE error codes.

    v3 -> v4

    * Decouple NE ioctl interface from KVM API.
    * Add NE API version and the corresponding ioctl call.
    * Add enclave / image load flags options.

    v2 -> v3

    * Remove the GPL additional wording as SPDX-License-Identifier is
    already in place.

    v1 -> v2

    * Add ioctl for getting enclave image load metadata.
    * Update NE_ENCLAVE_START ioctl name to NE_START_ENCLAVE.
    * Add entry in Documentation/userspace-api/ioctl/ioctl-number.rst for NE
    ioctls.
    * Update NE ioctls definition based on the updated ioctl range for major
    and minor.

    Add menu control for VP9 codec levels. A total of 14 levels are
    defined for Profile 0 (8bit) and Profile 2 (10bit). Each level
    is a set of constrained bitstreams coded with targeted resolutions,
    frame rates, and bitrates.

    The definitions have been taken from webm project [1].

  • 129134e54   media: media/v4l2: remove V4L2_FLAG_MEMORY_NON_CONSISTENT flag ... Browse Code »

    The patch partially reverts some of the UAPI bits of the buffer
    cache management hints. Namely, the queue consistency (memory
    coherency) user-space hint because, as it turned out, the kernel
    implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT.

    The patch reverts both kernel and user space parts: removes the
    DMA consistency attr functions, rolls back changes to v4l2_requestbuffers,
    v4l2_create_buffers structures and corresponding UAPI functions
    (plus compat32 layer) and cleans up the documentation.

    The only in-tree user for mbx driver for Intel 2700G graphics chip was
    cm-x270 platform. Since this platform was removed by the commit
    9d3239147d6d ("ARM: pxa: remove Compulab pxa2xx boards") there is no
    point to keep the obsolete framebuffer driver.
