media: coda: disable decoder crop selections

2019-11-10T06:27:40Z

Disable output side crop selections for the decoder. This fixes the following v4l2-compliance complaint: fail: v4l2-test-formats.cpp(1576): IS_DECODER(node) test Cropping: FAIL Signed-off-by: Philipp Zabel Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: coda: disable encoder compose selections

2019-11-10T06:26:11Z

Disable capture side compose selections for the encoder. This fixes the following v4l2-compliance complaint: fail: v4l2-test-formats.cpp(1662): IS_ENCODER(node) test Composing: FAIL Signed-off-by: Philipp Zabel Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: coda: drop unused irqlock

2019-11-09T08:10:42Z

The irqlock spinlock has been unused from the start. Remove it. Signed-off-by: Philipp Zabel Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: coda: request to skip kernel mapping for decoded buffers

2019-11-05T11:59:50Z

The kernel driver never touches the decoded buffers with the CPU. All accesses are either done by hardware DMA masters or userspace mapping the buffers. This means we don't need a kernel virtual address mapping for those buffers at all. As those buffers are usually quite large, we can save a good deal of kernel vmalloc space by requesting to not have a kernel mapping set up for them.

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

2019-11-05T11:59:19Z

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.

media: coda: set device_caps in struct video_device

2019-07-22T18:45:10Z

Instead of filling in the struct v4l2_capability device_caps field, fill in the struct video_device device_caps field. That way the V4L2 core knows what the capabilities of the video device are. Signed-off-by: Hans Verkuil Reviewed-by: Philipp Zabel Signed-off-by: Mauro Carvalho Chehab

media: coda: encoder parameter change support

2019-06-24T18:48:33Z

Add support for dynamically changing the GOP size, bitrate, frame rate, constant intra quantization parameter, number of intra refresh macro blocks and slice mode parameters. Signed-off-by: Philipp Zabel Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: coda: add coda_slice_mode() function

2019-06-24T18:47:39Z

Changing slice mode dynamically while encoding will require to calculate the register value again, so split it out into a separate function. Signed-off-by: Philipp Zabel Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: coda: store device pointer in driver structure instead of pdev

2019-06-24T18:46:42Z

Currently the platform device pointer is stored in struct coda_dev, only to convert it into a device pointer wherever it is used. Just store the device pointer directly. Signed-off-by: Philipp Zabel Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: coda: mark last returned frame

2019-06-24T18:45:53Z

If reordering is not enabled, the last decoded frame has to be the last returned buffer. Otherwise wait for the firmware to report no more frame to display. In that case the return buffer is the last one as well, and can be reported as such. Signed-off-by: Philipp Zabel Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
