As per current implementation, video driver is unvoting "videom-mem" path for last video session during vdec_session_release(). While video playback when we try to suspend device, we see video clock warnings since votes are already removed during vdec_session_release(). corrected this by putting dummy vote on "video-mem" after last video session release and unvoting it during suspend. suspend") Fixes: 07f8f22a ("media: venus: core: remove CNOC voting while device Signed-off-by:

Currently video driver is voting for venus0-ebi path during buffer processing with an average bandwidth of all the instances and unvoting during session release. While video streaming when we try to do XO-SD using the command "echo mem > /sys/power/state command" , device is not entering to suspend state and from interconnect summary seeing votes for venus0-ebi Corrected this by voting for venus0-ebi path in venus_runtime_resume() and unvote during venus_runtime_suspend(). suspend") Fixes: 07f8f22a ("media: venus: core: remove CNOC voting while device Signed-off-by:

Per the stateful codec specification, VIDIOC_G_SELECTION with a target of V4L2_SEL_TGT_COMPOSE is supposed to return the crop area of capture buffers containing the decoded frame. Until now the driver did not get that information from the firmware and just returned the dimensions of CAPTURE buffers. The firmware unfortunately does not always provide the crop information from the stream ; also make sure to detect when that happens and fallback to providing the coded size in these cases.

The default codec after driver open is set to be H264 but the instance format for capture is wrongly set to H263. Correct this to H264. For regular applications this is not a big issue because they set the format through S_FMT but for example v4l2-compliance does not. Signed-off-by:

To avoid potentially overflowing the kernel logs in the case of corrupted streams, this commit replaces an error message with a per-stream counter to be read through a driver-specific control. Applications can read the per-stream accumulated error macroblocks count. The old error message is replaced by a rate-limited debug message. Signed-off-by:

It's possible that the VPU was initialized using just one buffer, containing only codec headers. In this case, right after the initialization and after updating the FIFO read pointer, we need to iterate through all the coda_buffer_meta and release any metas that have been already used by the VPU. This issue is affecting indirectly the bitstream buffer fill threshold, which depends on the meta end position of the first queued meta, which is passed to coda_bitstream_can_fetch_past(). Without this fix, it's possible that for certain videos, the bitstream buffer level is not filled properly, resulting in a PIC_RUN timeout. Reported-by:

isif_probe() invokes iounmap() on error handling paths, but it does not reset the global state. So, later it can invoke iounmap() even when ioremap() fails. This is the case also for isif_remove(). The patch resets the global state after invoking iounmap() to avoid this. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:
