clk_prepare_enable() may fail, so we should better check its return value and propagate it in the case of error. Signed-off-by:

In addition to the S_FMT debug output, S_SELECTION (SEL_TGT_CROP) is relevant to determine encoded size. Add debug output for it. Signed-off-by:

Philipp Zabel authored
Consistently add the context index to debug output, which otherwise is impossible to make sense of when two contexts are running concurrently. For this purpose, add a convenience macro coda_dbg(). Use the function name with the coda_ prefix stripped as keyword where applicable, and consistently use vid-out and vid-cap names for the queues. Add sequence counters to the decoder job finished message and correctly indicate B frames. Add a start streaming message to complement the stop streaming message and a start encoding message to complement the existing start decoding message. Signed-off-by:

Philipp Zabel authored
v4l2-compliance complains about S_PARM being supported, but not ENUM_FRAMEINTERVALS. Report a continuous frame interval even though the hardware only supports 16-bit numerator and denominator, with min/max values that can be programmed into the mailbox registers. Signed-off-by:

The CODA driver uses threaded IRQs only, so there is nothing happening in hardirq context that could interfere with the buffer meta handling. Signed-off-by:

Three macroblocks seem to be the minimum resolution that can be encoded and decoded by the CODA960 h.264 codec. Picture run commands fail for smaller resolutions. Signed-off-by:

The ringbuffer used to hold the bitstream is very conservatively sized, as keyframes can get very large and still need to fit into this buffer. This means that the buffer is way oversized for the average stream to the extend that it will hold a few hundred frames when the video data is compressing well. The current strategy of queueing as much bitstream data as possible leads to large delays when draining the decoder. In order to keep the drain latency to a reasonable bound, try to only queue a full reorder window of buffers. We can't always hit this low target for very well compressible video data, as we might end up with less than the minimum amount of data that needs to be available to the bitstream prefetcher, so we must take this into account and allow more buffers to be queued in this case.

The bitstream prefetch unit reads data in 256 byte blocks with some kind of queueing. For the decoder to see data up to a desired position in the next run, the bitstream has to be filled for 2 256 byte blocks past that position aligned up to the next 256 byte boundary. This should make sure we never run into a buffer underrun condition if userspace does not supply new input buffers fast enough. Signed-off-by:

Storing the unmasked kfifo->in position as meta->start and ->end allows to more easily compare a point past meta->end with the current kfifo->in. Signed-off-by:

The ffz() return value is undefined if the instance mask does not contain any zeros. If it returned 32, the following set_bit would corrupt the debugfs_root pointer. Switch to IDA for context index allocation. This also removes the artificial 32 instance limit for all except CodaDx6. Signed-off-by:

Swapping the order between v4l2 subdevice registration and checking chip id in b7a41762 ("media: ov2680: don't register the v4l2 subdevice before checking chip ID") makes the mode restore to use the sensor controls before they are set, so move the mode restore call to s_power after the handler setup for controls is done. This remove also the need for the error code path in power on function. Fixes: b7a41762 ("media: ov2680: don't register the v4l2 subdevice before checking chip ID") Signed-off-by:
