Adapt vsp1_video_pipeline_run() such that it can iterate each partition required for constructing this frame's display list chain in the event that multiple display lists are required to process in hardware. The first display list is held as the head list object, whilst any following parition display lists are linked to the head by means of vsp1_dl_list_add_chain(). Linking the chained display list headers to process using the auto start mechanism of the hardware is performed during the vsp1_dl_list_commit(). Signed-off-by:

The partition algorithm needs to determine the capabilities of each entity in the pipeline to identify the correct maximum partition width. Extend the vsp1 entity operations to provide a max_width operation and use this call to calculate the number of partitions that will be processed by the algorithm. Gen 2 hardware does not require multiple partitioning, and as such will always return a single partition. Signed-off-by:

When display lists are linked in a chain, they will be processed automatically by the hardware, with each list linking to the next. Only on the last display list will the frame end interrupt be fired to mark the completion event. Upon frame-end, the chain will be iterated to release each display list back to the free list. The chained lists use case (image partitioning) can require up to 64 lists per frame in the worst case scenario, bump up the number of preallocated lists. Signed-off-by:

Replace the current boolean parameter (full / !full) with an explicit enum. - VSP1_ENTITY_PARAMS_INIT for parameters to be configured at pipeline initialization time only (V4L2 stream on or DRM atomic update) - VSP1_ENTITY_PARAMS_RUNTIME for all parameters that can be freely modified at runtime (through V4L2 controls) This will allow future extensions when implementing image partitioning support.

The frame-end function releases and completes the buffers on the input and output entities of the pipe before marking the pipe->state as 'STOPPED'. This introduces a race whereby with the pipe->state still 'RUNNING', a QBUF handler can commence processing a frame before the frame_end function has completed. In the event that this happens, a frame queued by QBUF hangs due to the incorrect pipe->state setting which prevents vsp1_pipeline_run from issuing a CMD_STRCMD. By locking the entire function we prevent this from occurring, but we also change the locking state of the buffer release code. This has been analysed visually as acceptable, but it must be considered that this now causes the video->irqlock to be taken under the pipe->irqlock context. Signed-off-by:

Pipelines can only be run if all their video nodes are streaming. Commit b4dfb9b3 ("[media] v4l: vsp1: Stop the pipeline upon the first STREAMOFF") fixed the pipeline stop sequence, but introduced a race condition that makes it possible to run a pipeline after stopping the stream on a video node by queuing a buffer on the other side of the pipeline. Fix this by clearing the buffers ready flag when stopping the stream, which will prevent the QBUF handler from running the pipeline.
