Backport a few fixes found in the course of getting mdp5 working. There is a window of time after pageflip is requested, before we start scanning out the new fb (ie. while we are waiting for gpu). During that time we need to continue holding a reference to the still-current scanout fb, to avoid the backing gem bo's from being destroyed. Possibly a common mdp_crtc parent class could be useful to share some of this logic between mdp4_crtc and mdp5_crtc. OTOH, this all can be removed from the driver once atomic is in place, as plane/crtc updates get deferred until all fb's are ready before calling in to .page_flip(), etc. Signed-off-by: Rob Clark <robdclark@gmail.com> |
