2022-12-31media: amphion: add lock around vdec_g_fmtMing Qian1-0/+2
[ Upstream commit 8480dd5fb3c82b5887d456b3fbe4201d99231814 ] the capture format may be changed when sequence header is parsed, it may be read and write in the same time, add lock around vdec_g_fmt to synchronize it Fixes: 6de8d628df6e ("media: amphion: add v4l2 m2m vpu decoder stateful driver") Signed-off-by: Ming Qian <ming.qian@nxp.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Sasha Levin <sashal@kernel.org>
2022-12-31media: amphion: reset instance if it's aborted before codec header parsedMing Qian1-3/+10
[ Upstream commit 3984ea32e83bcad06b4b034ddd4b0a934c1b2f91 ] there is hardware limitation that if it's aborted before the first codec header parsed, the codec may be stalled unless we do reset codec. and drop the source change event if it's triggered after reset.

2022-08-30media: amphion: don't change the colorspace reported by decoder.Ming Qian1-8/+8
decoder will report the colorspace information which is parsed from the sequence header, if they are unspecified, just let application to determine it, don't change it in driver.

2022-07-08media: amphion: only insert the first sequence startcode for vc1l formatMing Qian1-1/+1
For format V4L2_PIX_FMT_VC1_ANNEX_L, the amphion vpu requires driver to help insert some custom startcode before sequence and frame. but only the first sequence startcode is needed, the extra startcode will cause decoding error. So after seek, we don't need to insert the sequence startcode. In other words, for V4L2_PIX_FMT_VC1_ANNEX_L, the vpu doesn't support dynamic resolution change.

2022-07-08media: amphion: defer setting last_buffer_dequeued until resolution changes ↵Ming Qian1-14/+22
are processed Don't set last_buffer_dequeued during dynamic resolution change, otherwise it may be cleared in handling resolution change, as streamoff may be called in dynamic resolution change. Normally, this does not happen. But we encounter a special testcase, User issue V4L2_DEC_CMD_STOP after enqueue one buffer that only contains codec config header, but not any frame data. So VPU report the parsed resolution, then report the eos event. So driver should notify user to handle resolution change first, after it's handled, set the last_buffer_dequeued. then the user can exit decoding normally. Otherwise the user may be stalled.

2022-05-13media: amphion: free ctrl handler if error is set and return errorMing Qian1-0/+6
The typical behavior is to add all controls, then at the end check if hdl->error was set, and if so, v4l2_ctrl_handler_free is called and the error is returned.

2022-05-13media: amphion: decoder copy timestamp from output to captureMing Qian1-49/+27
copy the timestamp using the helper function V4L2_BUF_FLAG_TIMESTAMP_COPY To implement this, driver will keep the output buffer until it's decoded, in previous, driver will return the output buffer immediately after copying data to stream buffer. After that, there is no need to make a workaround for poll function. driver can use v4l2_m2m_fop_poll directly. Also, driver don't need to keep a input threshold as the buffer count is up to only 32.

For interlaced frame, the amphion vpu will store the two fields sequential into one buffer, top-bottom order so the field should be set to V4L2_FIELD_SEQ_TB. fix the previous bug that set it to V4L2_FIELD_SEQ_BT wrongly.
