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:

The H3 has a slightly different CSI controller (no BT656, no CCI) which looks a lot like the original A31 controller. Add a compatible for the A31, and more specific compatible the for the H3 to be used in combination for the A31. Reviewed-by:

The video device release() callback for video-i2c driver frees the whole struct video_i2c_data. If there is no user left for the video device when video_unregister_device() is called, the release callback is executed. However, in video_i2c_remove() some fields (v4l2_dev, lock, and queue_lock) in struct video_i2c_data are still accessed after video_unregister_device() is called. This fixes the use after free by moving the code from video_i2c_remove() to the release() callback. Fixes: 5cebaac6 ("media: video-i2c: add video-i2c driver") Reviewed-by:
