media: coda: Add check for kmalloc

2023-01-18T10:41:12Z

[ Upstream commit 6e5e5defdb8b0186312c2f855ace175aee6daf9b ] As the kmalloc may return NULL pointer, it should be better to check the return value in order to avoid NULL poineter dereference, same as the others.

media: coda: Add more H264 levels for CODA960

2022-06-14T16:11:47Z

commit eb2fd187abc878a2dfad46902becb74963473c7d upstream. Add H264 level 1.0, 4.1, 4.2 to the list of supported formats. While the hardware does not fully support these levels, it does support most of them. The constraints on frame size and pixel formats already cover the limitation. This fixes negotiation of level on GStreamer 1.17.1.

media: coda: Fix reported H264 profile

2022-06-14T16:11:47Z

commit 7110c08ea71953a7fc342f0b76046f72442cf26c upstream. The CODA960 manual states that ASO/FMO features of baseline are not supported, so for this reason this driver should only report constrained baseline support. This fixes negotiation issue with constrained baseline content on GStreamer 1.17.1. ASO/FMO features are unsupported for the encoder and untested for the decoder because there is currently no userspace support. Neither GStreamer parsers nor FFMPEG parsers support ASO/FMO.

media: coda: limit frame interval enumeration to supported encoder frame sizes

2022-06-14T16:11:28Z

[ Upstream commit 67e33dd957880879e785cfea83a3aa24bd5c5577 ] Let VIDIOC_ENUM_FRAMEINTERVALS return -EINVAL if userspace queries frame intervals for frame sizes unsupported by the encoder. Fixes the following v4l2-compliance failure: fail: v4l2-test-formats.cpp(123): found frame intervals for invalid size 47x16 fail: v4l2-test-formats.cpp(282): node->codec_mask & STATEFUL_ENCODER test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: FAIL [hverkuil: drop incorrect 'For decoder devices, return -ENOTTY.' in the commit log] Signed-off-by: Philipp Zabel Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Sasha Levin

[ Upstream commit 44693d74f5653f82cd7ca0fe730eed0f6b83306a ] The frame memory control register value is currently determined before userspace selects the final capture format and never corrected. Update ctx->frame_mem_ctrl in __coda_start_decoding() to fix decoding into YUV420 or YVU420 capture buffers.

media: coda: fix deadlock between decoder picture run and start command

2020-01-17T18:48:57Z

commit a3fd80198de6ab98a205cf7fb148d88e9e1c44bb upstream. The BIT decoder picture run temporarily locks the bitstream mutex while the coda device mutex is locked, to refill the bitstream ring buffer. Consequently, the decoder start command, which locks both mutexes when flushing the bitstream ring buffer, must lock the coda device mutex first as well, to avoid an ABBA deadlock.
