media: mtk-vcodec: make IRQs disabled upon request

2020-09-26T08:12:09Z

The driver requests IRQs to disable them immediately. This is potentially racy, fix this by requesting the IRQs to come disabled instead using the IRQ_NOAUTOEN flag of irq_set_status_flags().

media: mtk-vcodec: venc: fix invalid time per frame in S_PARM

2020-09-26T08:11:26Z

v4l2-compliance expects the driver to adjust the time per frame if it is invalid (numerator or denominator set to 0). Adjust it to the default value in these cases. Signed-off-by: Alexandre Courbot Acked-by: Tiffany Lin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mtk-vcodec: venc: set default time per frame

2020-09-26T08:11:01Z

The time per frame was left initialized to 0/0, which make the driver fail v4l2-compliance, and also leaves it potentially exposed to doing a division by zero. Signed-off-by: Alexandre Courbot Acked-by: Tiffany Lin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mtk-vcodec: venc: support ENUM_FRAMESIZES on OUTPUT formats

2020-09-26T08:10:40Z

v4l2-compliance requires ENUM_FRAMESIZES to support OUTPUT formats. Reuse mtk_venc_find_format() to make sure both queues are considered when serving an ENUM_FRAMESIZES.

media: mtk-vcodec: venc: use platform data for ENUM_FRAMESIZES

2020-09-26T08:10:07Z

vidioc_enum_framesizes() assumes that all encoders support H.264 and VP8, which is not necessarily true and requires to duplicate information about the supported codecs which is already stored in the platform data. Fix this by referring to the platform data to find out whether a given format is supported. Since the supported sizes are all the same regardless of the format, we can then return a copy of a static value if the format is supported.

media: mtk-vcodec: venc: set OUTPUT buffers field to V4L2_FIELD_NONE

2020-09-26T08:09:34Z

A default value of 0 means V4L2_FIELD_ANY, which is not correct. Reported by v4l2-compliance. Signed-off-by: Alexandre Courbot Acked-by: Tiffany Lin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mtk-vcodec: venc support MIN_OUTPUT_BUFFERS control

2020-09-26T08:09:09Z

This control is required by v4l2-compliance for encoders. A value of 1 should be suitable for all scenarios. Signed-off-by: Alexandre Courbot Acked-by: Tiffany Lin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: Revert "media: mtk-vcodec: Remove extra area allocation in an input buffer on encoding"

2020-09-26T08:08:49Z

This reverts commit 81735ecb62f882853a37a8c157407ec4aed44fd0. The hardware needs data to follow the previous alignment, so this extra space was not superfluous after all. Besides, this also made v4l2-compliance's G_FMT and S_FMT tests regress. Signed-off-by: Alexandre Courbot Acked-by: Tiffany Lin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

Now that all the supporting blocks are present, enable encoder for MT8183. [acourbot: refactor, cleanup and split] Signed-off-by: Yunfei Dong Co-developed-by: Alexandre Courbot Signed-off-by: Alexandre Courbot Acked-by: Tiffany Lin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mtk-vcodec: venc: specify supported formats per-chip

2020-09-26T08:06:08Z

Different chips have different supported formats. Move the list of supported formats to the platform data, and split the output and capture formats into two lists to make it easier to find the default format for each queue.
