* [media] v4l: vsp1: Support multiple partitions per frameKieran Bingham2016-09-19
| | | | | | | | | | | | | | | | | | 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().

* [media] v4l: vsp1: Determine partition requirements for scaled imagesKieran Bingham2016-09-19
| | | | | | | | | | | | | | | | | 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.

* [media] v4l: vsp1: Repair race between frame end and qbuf handlerKieran Bingham2016-09-19
| | | | | | | | | | | | | | | | | | | | | 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.

* [media] v4l: vsp1: Prevent pipelines from running when not streamingLaurent Pinchart2016-09-19
| | | | | | | | | | | | | | | | | | | Pipelines can only be run if all their video nodes are streaming. Commit b4dfb9b35a19 ("[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.

| * [media] v4l: vsp1: Support runtime modification of controlsLaurent Pinchart2016-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Controls are applied to the hardware in the configure operation of the VSP entities, which is only called when starting the video stream. To enable runtime modification of controls we need to call the configure operations for every frame. Doing so is currently not safe, as most parameters shouldn't be modified during streaming. Furthermore the configure operation can sleep, preventing it from being called from the frame completion interrupt handler for the next frame. Fix this by adding an argument to the configure operation to tell entities whether to perform a full configuration (as done now) or a partial runtime configuration. In the latter case the operation will only configure the subset of parameters related to runtime-configurable controls, and won't be allowed to sleep when doing so. Because partial reconfiguration can depend on parameters computed when performing a full configuration, the core guarantees that the configure operation will always be called with full and partial modes in that order at stream start. Entities thus don't have to duplicate configuration steps in the full and partial code paths. This change affects the VSP driver core only, all entities return immediately from the configure operation when called for a partial runtime configuration. Entities will be modified one by one in further commits. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device is stopped when STREAMOFF is called on the last video node in the pipeline. This results in possible memory corruption and/or crashes, as userspace could free buffers while the hardware is still writing to them, and the frame completion interrupt handler could try to access buffers that don't exist anymore. Fix this by stopping the pipeline upon the first STREAMOFF call, not the last.

* [media] v4l: vsp1: Don't configure RPF memory buffers before calculating offsetsLaurent Pinchart2016-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | The RPF source memory pointers need to be offset to take the crop rectangle into account. Offsets are computed in the RPF stream start, which can happen (when using the DRM pipeline) after calling the RPF .set_memory() operation that programs the buffer addresses. The .set_memory() operation tries to guard against the problem by skipping programming of the registers when the module isn't streaming. This will however only protect the first use of an RPF in a DRM pipeline, as in all subsequent uses the module streaming flag will be set and the .set_memory() operation will use potentially incorrect offsets. Fix this by allowing the caller to decide whether to program the hardware immediately or just cache the addresses. While at it refactor the memory set code and create a new vsp1_rwpf_set_memory() that cache addresses and calls the .set_memory() operation to apply them to the hardware. As a side effect the driver now writes all three DMA address registers regardless of the number of planes, and initializes unused addresses to zero.
