  • 72148d1a5   media: v4l: Add support for V4L2_BUF_TYPE_META_OUTPUT ... Browse Code »

    The V4L2_BUF_TYPE_META_OUTPUT mirrors the V4L2_BUF_TYPE_META_CAPTURE with
    the exception that it is an OUTPUT type. The use case for this is to pass
    buffers to the device that are not image data but metadata. The formats,
    just as the metadata capture formats, are typically device specific and
    highly structured.

  • 73a110623   media: v4l2-core: push taking ioctl mutex down to ioctl handler ... Browse Code »

    The ioctl serialization mutex (vdev->lock or q->lock for vb2 queues)
    was taken at the highest level in v4l2-dev.c. This prevents more
    fine-grained locking since at that level we cannot examine the ioctl
    arguments, we can only do that after video_usercopy is called.

    So push the locking down to __video_do_ioctl() and subdev_do_ioctl_lock().

    This also allows us to make a few functions in v4l2-ioctl.c static and
    video_usercopy() is no longer exported.

    The locking scheme is not changed by this patch, just pushed down.

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • 2438e78a4   [media] v4l2-core: drop g/s_priority ops ... Browse Code »

    The handling of VIDIOC_G/S_PRIORITY is now entirely done by the V4L2
    core, so we can drop the g/s_priority ioctl ops.

    We do have to make sure though that when S_PRIORITY is called we check
    that the driver used struct v4l2_fh. This check can be removed once all
    drivers are converted to that structure.

  • 17028cdb7   [media] v4l2 core: improve debug flag handling ... Browse Code »

    The old debug field is renamed to dev_debug to ensure that existing drivers
    (including out-of-tree drivers) that try to use the old name will no longer
    compile. A comment has also been added that makes it explicit that drivers
    shouldn't use this field.

    Additional bits have been added to the debug flag to be more fine-grained
    when debugging, especially when dealing with streaming ioctls and read,
    write and poll. You want to enable those explicitly to prevent flooding
    the log when streaming unless you actually want to do that.

  • 79b0c6400   [media] v4l2: add new VIDIOC_DBG_G_CHIP_NAME ioctl ... Browse Code »

    Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl.
    This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done
    by the name or index of subdevices or an index to a bridge chip. Most of this
    can all be done automatically, so most drivers just need to provide get/set
    register ops.
    In particular, it is now possible to get/set subdev registers without
    requiring assistance of the bridge driver.
