Rightly or wrongly, https://github.com/raspberrypi/linux/blob/rpi-6.12.y/drivers/gpu/drm/vc4/vc4_plane.c#L2571 only lets ptr0_offset[0] change with an async update. ptr0_offset[1] and ptr0_offset[2] can't change. I think that means that we can't (currently) update the chroma planes of a YUV/YVU frame with an async update, so there's no issue. When someone complains about async YUV updates I'll take another look. Dropping the draft status. |

Draft as I want to double check the async update path too.
