2020-05-05media: venus: venc,vdec: Return EBUSY on S_FMT while streamingStanimir Varbanov1-0/+8
According to the v4l spec s_fmt must return EBUSY while the particular queue is streaming. Add such check in encoder and decoder s_fmt methods. Signed-off-by: Stanimir Varbanov <stanimir.varbanov@linaro.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-05-05media: venus: Mark last capture bufferStanimir Varbanov1-5/+40
According to stateful Codec API the decoder will process all remaining buffers from before the source change event in dynamic-resolution-change state and mark the last buffer with V4L2_BUF_FLAG_LAST. In Venus case the firmware doesn't mark that last buffer and some mechanism have to be created in v4l decoder driver. Fortunately the firmware interface (HFI) claims that the decoder output buffers will be returned to v4l decoder driver before it send the insufficient event. In order to do that we save last queued in the driver capture buffer in the event_notify and issue flush on output firmware buffers queue. Once the saved buffer is returned (as a result of flush command) we mark it as LAST. For all that possible we extend HFI flush command with one more argument and one more flush_done HFI driver callback.

Once the hfi_session_flush is issued by the vdec all queued buffers to firmware should be returned to the v4l driver. Some of those buffers are not processed at the time of flush command, those buffers has filled len zero (no data). Catch that in buffer_done callback and mark not filled capture buffers with error state so that client can discard them.

2020-05-05media: venus: helpers: Done buffers per queue typeStanimir Varbanov1-3/+2
Currently calling venus_helper_buffers_done() will return buffers to user for both capture and output queues in the same call. This is wrong because both queues are really separate and calling stop_streaming on one queue shouldn't return buffers for the other. Solve this by add a new queue type argument and fix the clients of the helper function.

2018-07-25media: venus: implementing multi-stream supportStanimir Varbanov1-2/+91
This is implementing multi-stream decoder support. The multi-stream will be used to enable/disable the primary/secondary decoder outputs. Depending on formats on both decoder outputs we could implement downscale, dithering and supporting UBWC (universal bandwidth compression) formats. The UBWC compressed raw format is used to optimize interconnect bandwidth for bigger resolutions like 4K and hence we will get some power-saving benefits as well. Both decoder outputs are distinguished by buffer_type field in the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary decoder output. Starting from Venus 4xx the DPB buffers format must be UBWC, so the multi-stream becomes mandatory for this Venus version. That means that we need to allocate internally in the driver a set of DPB buffers (with UBWC NV12 format) and give them to the firmware. The other decoder output (we called it OPB) format will be NV12 linear format and with the same resolution (or smaller in case the user wants to downscale). The DPB buffers are used for decoder reference frames and those have to be in a specific format (UBWC). So one decoder output is used to fill those reference buffers while the other output is used to fill the userspace buffers with the user requested format.
