media: vsp1: Add premultiplied alpha support

2022-09-07T20:48:39Z

To support DRM blend mode in R-Car DU driver, we must be able to pass a plane with the premultiplied alpha. Adding a new property to vsp1_du_atomic_config allows the R-Car DU driver to pass the premultiplied alpha plane.

media: vsp1: drm: Implement writeback support

2019-03-18T15:24:14Z

Extend the vsp1_du_atomic_flush() API with writeback support by adding format, pitch and memory addresses of the writeback framebuffer. Writeback completion is reported through the existing frame completion callback with a new VSP1_DU_STATUS_WRITEBACK status flag.

The VSP1 driver will need to pass extra flags to the DU through the frame completion API. Replace the completed bool flag by a bitmask to support this. Signed-off-by: Laurent Pinchart Reviewed-by: Kieran Bingham Reviewed-by: Mauro Carvalho Chehab

YCbCr planar formats can have different pitch values for the luma and chroma planes. This isn't taken into account in the driver. Fix it. Based on a BSP patch from Koji Matsuoka .

media: vsp1: Support Interlaced display pipelines

2018-08-03T20:02:27Z

Calculate the top and bottom fields for the interlaced frames and utilise the extended display list command feature to implement the auto-field operations. This allows the DU to update the VSP2 registers dynamically based upon the currently processing field.

drm: rcar-du: Repair vblank for DRM page flips using the VSP

2017-08-03T13:17:30Z

The driver recently switched from handling page flip completion in the DU vertical blanking handler to the VSP frame end handler to fix a race condition. This unfortunately resulted in incorrect timestamps in the vertical blanking events sent to userspace as vertical blanking is now handled after sending the event. To fix this we must reverse the order of the two operations. The easiest way is to handle vertical blanking in the VSP frame end handler before sending the event. The VSP frame end interrupt occurs approximately 50µs earlier than the DU frame end interrupt, but this should not cause any undue harm. As we need to handle vertical blanking even when page flip completion is delayed, the VSP driver now needs to call the frame end completion callback unconditionally, with a new argument to report whether page flip has completed. With this new scheme the DU vertical blanking interrupt isn't needed anymore, so we can stop enabling it.
