Subject: [PATCH v5 00/14] media: mtk-vcodec: support for MT8183 decoder
Date: Wed, 19 May 2021 23:29:57 +0900	[thread overview]
Message-ID: <20210519143011.1175546-1-acourbot@chromium.org> (raw)

This series adds support for the stateless API into mtk-vcodec, by first
separating the stateful ops into their own source file, and introducing
a new set of ops suitable for stateless decoding. As such, support for
stateful decoders should remain completely unaffected.

This series has been tested with both MT8183 and MT8173. Decoding was
working for both chips, and in the case of MT8173 no regression has been
spotted.

Patches 1-5 fix a few compliance issues with the decoder and encoder, most
notably by adding support for the START and STOP command for the latter. These
patches were last in the previous series but have been moved to the beginning so
they can be applied sooner.

Patches 6-9 separates the "stateful" part of the driver into its own file and
add support for the new firmware and pixel format used by MT8183.

Patches 10-14 add support for H.264 stateless decoding and MT8183.

Changes since v4:
* Moved compliance fix patches to the head of the series.
* Select MEDIA_CONTROLLER_REQUEST_API.
* Properly capitalize MM21's format description string.
* Reorganize stateless code as suggested by Hans.
* Fix compilation errors when DEBUG is defined.
* Merge double-free fixup patch into the patch that introduced the issue (was
  a separate patch coming right after the one introducing the issue).

Changes since v3:
* Stop checking that controls are set for every request.
* Add V4L2_CID_STATELESS_H264_START_CODE control.
* Stop mapping OUTPUT buffers and getting the NAL type from them, use the
  nal_ref_idc field instead.
* Make V4L2_CID_MIN_BUFFERS_FOR_CAPTURE control stateful-only.
* Set vb2_buffer's field to V4L2_FIELD_NONE in buffer validation hook.

Changes since v2:
* Add follow-up patches fixing support for START/STOP commands for the
  encoder, and stateful decoder.
