If debug_phys_addr is set, then CEC_CAP_PHYS_ADDR is added to the CEC adapter capabilities. This allows for testing CEC even if the physical address isn't set. This makes it possible to connect two HDMI outputs together and still use CEC. Very useful for testing CEC if you don't have access to an HDMI receiver under linux. Signed-off-by:

The CEC specification requires that the Vendor ID (if any) is reported after a logical address was claimed. This was never done, so add support for this. Signed-off-by:

The CEC IP is very similar between the three HDMI receivers, but not identical. Add support for all three variants. Tested with an adv7604 and an adv7612. Signed-off-by:

If a filehandle is dup()ped, then it is possible to close it from one fd and call mmap from the other. This creates a race condition in vb2_mmap where it is using queue data that __vb2_queue_free (called from close()) is in the process of releasing. By moving up the mutex_lock(mmap_lock) in vb2_mmap this race is avoided since __vb2_queue_free is called with the same mutex locked. So vb2_mmap now reads consistent buffer data. Signed-off-by:

If the tx_ignore_nack_until_eom error injection was activated, then tx_nacked was never set instead of setting it when the last byte of the message was transmitted. As a result the transmit was marked as OK, when it should have been NACKed. Modify the condition so that it always sets tx_nacked when the last byte of the message was transmitted. Signed-off-by:

The R-Car CSI-2 interface has a number of selectable 'channels' that provides pixel data to the VINs during image acquisition. Each channel can be used to match a CSI-2 data type and a CSI-2 virtual channel to be routed to output path. Different SoCs have different number of channels, with R-Car E3 being the notable exception supporting only 2 of them. Reviewed-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:

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:

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:
