2022-12-31media: amphion: lock and check m2m_ctx in event handlerMing Qian1-2/+6
[ Upstream commit 1ade3f3f16986cd7c6fce02feede957f03eb8a42 ] driver needs to cancel vpu before releasing the vpu instance, so call v4l2_m2m_ctx_release() first, to handle the redundant event triggered after m2m_ctx is released. lock and check m2m_ctx in the event handler.

2022-07-08media: amphion: defer setting last_buffer_dequeued until resolution changes ↵Ming Qian1-1/+1
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: decoder copy timestamp from output to captureMing Qian1-0/+56
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.
