Subject: [PATCH v7 00/13] Add HANTRO G2/HEVC decoder support for IMX8MQ
The IMX8MQ got two VPUs but until now only G1 has been enabled.
This series aim to add the second VPU (aka G2) and provide basic
HEVC decoding support.
To be able to decode HEVC it is needed to add/update some of the
structures in the uapi. In addition of them one HANTRO dedicated
control is required to inform the driver of the numbre of bits to skip
at the beginning of the slice header.
The hardware require to allocate few auxiliary buffers to store the
references frame or tile size data.
The driver has been tested with fluster test suite stream.
For example with this command: ./fluster.py run -ts JCT-VC-HEVC_V1 -d GStreamer-H.265-V4L2SL-Gst1.0
Finally the both VPUs will have a node the device-tree and be
independent from v4l2 point of view.
A branch with all the dev is available here:
https://gitlab.collabora.com/benjamin.gaignard/for-upstream/-/commits/upstream_g2_v7
version 7:
- Remove 'q' from syscon phandle name to make usable for iMX8MM too.
Update the bindings documentation.
- Add review/ack tags.
- Rebase on top of media_tree/master
- Be more accurate when computing the size of the memory needed motion
vectors.
- Explain why the all clocks need to set in the both DT node.
version 6:
- fix the errors reported by kernel test robot
version 5:
- use syscon instead of VPU reset driver.
- Do not break kernel/DT backward compatibility.
- Add documentation for dedicated Hantro control.
- Fix the remarks done by Ezequeil (typo, comments, unused function)
- Run v4l2-compliance without errors (see below).
- Do not add field to distinguish version, check postproc reg instead
version 4:
- Split the changes in hevc controls in 2 commits to make them easier to
review.
- Change hantro_codec_ops run() prototype to return errors
- Hantro v4l2 dedicated control is now only an integer
- rebase on top of VPU reset changes posted here:
https://www.spinics.net/lists/arm-kernel/msg878440.html
- Various fix from previous remarks
- Limit the modifications in API to what the driver needs
version 3:
- Fix typo in Hantro v4l2 dedicated control
- Add documentation for the new structures and fields
- Rebased on top of media_tree for-linus-5.12-rc1 tag
version 2:
- remove all change related to scaling
- squash commits to a coherent split
- be more verbose about the added fields
- fix the comments done by Ezequiel about dma_alloc_coherent usage
- fix Dan's comments about control copy, reverse the test logic
in tile_buffer_reallocate, rework some goto and return cases.
- be more verbose about why I change the bindings
- remove all sign-off expect mime since it is confusing
- remove useless clocks in VPUs nodes
