2024-12-04include: media-bus-formats: Add Mali-C55 mbus codesJacopo Mondi
Add media bus codes introduced by the Mali C55 ISP support to describe the 20-bit input formats supported by the ISP. This manual addition is a temporary measure until the kernel driver changes are merged, from which point this will be managed through the usual merge of the upstream kernel headers. Add the following formats - MEDIA_BUS_FMT_RGB202020_1X60 for processed input formats https://lore.kernel.org/linux-media/20241106100534.768400-2-dan.scally@ideasonboard.com/ - MEDIA_BUS_FMT_SBGGR20_1X20 MEDIA_BUS_FMT_SGBRG20_1X20 MEDIA_BUS_FMT_SGRBG20_1X20 MEDIA_BUS_FMT_SRGGB20_1X20 for the RAW bayer input format https://lore.kernel.org/linux-media/20241106100534.768400-3-dan.scally@ideasonboard.com/ Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Daniel Scally <dan.scally@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Signed-off-by: Daniel Scally <dan.scally@ideasonboard.com>
2024-06-03include: linux: Update kernel headers to version v6.10-rc1Hans de Goede
Updated kernel headers to v6.10-rc1 using utils/update-kernel-headers.sh and re-instating libcamera local modifications. This includes adding include/linux/udmabuf.h which was not part of libcamera's include/linux headers before.

2024-01-17include: linux: Update kernel headers to version v6.7Laurent Pinchart
Update kernel headers to v6.7 using utils/update-kernel-headers.sh and re-instating libcamera local modifications. The V4L2_SUBDEV_CAP_MPLEXED flag has been renamed to V4L2_SUBDEV_CAP_STREAMS in the upstream streams API. Adapt the code base accordingly. The flag's numerical value hasn't changed, there is no ABI breakage introduced by the API update.

2021-03-03include: linux: Update Linux headers to v5.12-rc1Laurent Pinchart
Update Linux headers to v5.12-rc1, to provide the MEDIA_ENT_F_PROC_VIDEO_ISP entity function. The DRM FourCC and modifiers that were manually added in commits 9db0ed5e2065, 38f2efb05cef and 90c793c6989f are kept. New Intel DRM format modifiers are conflicting with IPU3_FORMAT_MOD_PACKED, which is updated as a result. The V4L2 controls and formats that were manually added in commit 43d81d43fe91 are kept. This causes a conflict in the V4L2 control base for V4L2_CID_USER_BCM2835_ISP_BASE that needs to be resolved in the downstream Raspberry Pi kernel first. The intel-ipu3.h header is manually exported with the scripts/headers_install.sh script. The script complained about a missing "WITH Linux-syscall-note" license extension, which has been worked around manually. The issue has been reported upstream in [1].

2019-10-28include: linux: Update headers to Linux v5.2Jacopo Mondi
Update headers to Linux v5.2. The Rockchip ISP1 formats that were added manually in commit 97dce7a13fa3 ("include: linux: Add rkisp1 kernel header and format definitions") are kept. Otherwise the headers come straight from the upstream kernel. Signed-off-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

$name: Determine the ABI/API compatibility of two build versions

  $name [--help] [--abi-dir=<PATH>] [--tmp-dir=<PATH>] ARGS

The positional arguments (ARGS) determine the versions that will be compared and
take three variants:

  - No positional arguments:
      $name [optional arguments]

      It is assumed to compare the current git HEAD against the most recent TAG

  - One positional argument:
      $name [optional aguments] COMMITISH

      The given COMMITISH is compared against it's most recent TAG

  - Two positional arguments:
      $name [optional aguments] BASE COMMITISH

      The given COMMITISH is compared against the given BASE.

Optional Arguments:
  --abi-dir <path> Use <path> for storing (or retrieving existing) ABI data
                   files

  --tmp-dir <path> Specify temporary build location for building ABI data.
                   This could be a tmpfs/RAM disk to save on disk writes.
