Hi Daniel I come to the conclusion that (only) Atomic Weston will solve all of my troubles, so let's forget these patches (and work for atomic weston). By the way, is the expected behavior (Vblank - sync'ed or not) of drmModeSetPlane() described anywhere? The last time I browsed the related documentation I could not find the answer. Maybe something that needs to be clarified ? I will also re-send patch 1 & 5 out of this abandoned series since they make sense independently of this (a)sync stuff. BR.
