[PATCH v5 00/10] media: rkvdec: Add H.264 High 10 and 4:2:2 profile support

[Jonas Karlman]

This is a re-revival of an old series [1] now that NV15/NV20/NV30 support
for display driver have landed in linux v6.7.

This series adds H.264 High 10 and 4:2:2 profile support to the Rockchip
Video Decoder driver.

Patch 1 adds helpers for calculating plane bytesperline and sizeimage.
Patch 2 adds two new pixelformats for semi-planer 10-bit 4:2:0/4:2:2 YUV.

Patch 3 change to use bytesperline and buffer height to configure strides.
Patch 4 change to use values from SPS/PPS control to configure the HW.

Patch 5-9 refactor code to support filtering of CAPUTRE formats based
on the image format returned from a get_image_fmt ops.

Patch 10 adds final bits to support H.264 High 10 and 4:2:2 profiles.

Tested on a ROCK Pi 4 (RK3399) and Rock64 (RK3328):

  v4l2-compliance 1.26.1, 64 bits, 64-bit time_t
  ...
  Total for rkvdec device /dev/video3: 47, Succeeded: 47, Failed: 0, Warnings: 0

  Running test suite JVT-FR-EXT with decoder FFmpeg-H.264-V4L2-request
  ...
  Ran 65/69 tests successfully

  Running test suite JVT-AVC_V1 with decoder FFmpeg-H.264-V4L2-request
  ...
  Ran 129/135 tests successfully

Before this series:

  Running test suite JVT-FR-EXT with decoder FFmpeg-H.264-V4L2-request
  ...
  Ran 44/69 tests successfully

Changes in v5:
- Drop Remove SPS validation at streaming start patch
- Move buffer align from rkvdec_fill_decoded_pixfmt to min/step_width
- Use correct profiles for V4L2_CID_MPEG_VIDEO_H264_PROFILE
- Collect r-b and t-b tags
- Fluster test score same as v4, see [4] and [5]
Link to v4: https://lore.kernel.org/linux-media/20231105165521.3592037-1-jonas@kwiboo.se/

Changes in v4:
- Fix failed v4l2-compliance tests related to CAPTURE queue
- Rework CAPTURE format filter anv validate to use an image format
- Run fluster test suite JVT-FR-EXT [4] and JVT-AVC_V1 [5]
Link to v3: https://lore.kernel.org/linux-media/20231029183427.1781554-1-jonas@kwiboo.se/

Changes in v3:
- Drop merged patches
- Use bpp and bpp_div instead of prior misuse of block_w/block_h
- New patch to use values from SPS/PPS control to configure the HW
- New patch to remove an unnecessary call to validate sps at streaming start
- Reworked pixel format validation
Link to v2: https://lore.kernel.org/linux-media/20200706215430.22859-1-jonas@kwiboo.se/

Changes in v2:
- Collect r-b tags
- SPS pic width and height in mbs validation moved to rkvdec_try_ctrl
- New patch to not override output buffer sizeimage
- Reworked pixel format validation
- Only align decoded buffer instead of changing frmsize step_width

To fully runtime test this series you may need ffmpeg patches from [2],
this series is also available at [3].
