When using vb2 for video decoding, dequeued capture buffers may still be accessed by the hardware: this is the case when they are used as reference frames for decoding subsequent frames. When the buffer is imported with dma-buf, it needs to be mapped before access. Until now, it was mapped when queuing and unmapped when dequeuing, which doesn't work for access as a reference frames. One way to solve this would be to map the buffer again when it is needed as a reference, but the mapping/unmapping operations can seriously impact performance. As a result, map the buffer once (when it is first needed when queued) and keep it mapped until it is freed.

This reverts commit cf20ae15. The vb2_find_timestamp helper was modified to allow finding buffers regardless of their current state in the queue. This means that we no longer have to take particular care of references to the current capture buffer. Signed-off-by:

There really is no reason why vb2_find_timestamp can't just find buffers in any state. Drop that part of the test. This also means that vb->timestamp should only be set to 0 when the driver doesn't copy timestamps. This change allows for more efficient pipelining (i.e. you can use a buffer for a reference frame even when it is queued). Signed-off-by:

Upstream must be stopped immediately after receiving the last EOF and before disabling the IDMA channel. This can be accomplished by moving upstream stream off to just after receiving the last EOF completion in prp_stop(). For symmetry also move upstream stream on to end of prp_start(). This fixes a complete system hard lockup on the SabreAuto when streaming from the ADV7180, by repeatedly sending a stream off immediately followed by stream on: while true; do v4l2-ctl -d1 --stream-mmap --stream-count=3; done Eventually this either causes the system lockup or EOF timeouts at all subsequent stream on, until a system reset. The lockup occurs when disabling the IDMA channel at stream off. Stopping the video data stream entering the IDMA channel before disabling the channel itself appears to be a reliable fix for the hard lockup.

Move upstream stream off to just after receiving the last EOF completion and disabling the CSI (and thus before disabling the IDMA channel) in csi_stop(). For symmetry also move upstream stream on to beginning of csi_start(). Doing this makes csi_s_stream() more symmetric with prp_s_stream() which will require the same change to fix a hard lockup.

Disable the CSI immediately after receiving the last EOF before stream off (and thus before disabling the IDMA channel). Do this by moving the wait for EOF completion into a new function csi_idmac_wait_last_eof(). This fixes a complete system hard lockup on the SabreAuto when streaming from the ADV7180, by repeatedly sending a stream off immediately followed by stream on: while true; do v4l2-ctl -d4 --stream-mmap --stream-count=3; done Eventually this either causes the system lockup or EOF timeouts at all subsequent stream on, until a system reset. The lockup occurs when disabling the IDMA channel at stream off. Disabling the CSI before disabling the IDMA channel appears to be a reliable fix for the hard lockup.
