This likely does not really fit exactly in modesetting rework so sorry if i hijack this thread a bit. I have been thinking to vblank stuff in drm and i am wondering if while rearchitecturing the drm it would be nice to get rid of current vblank things and use fence instead. So having special fence for vblank, with a vblank fence queue for each crtc. If this was already in some plan ignore this mail :). Btw i think that some GPU can wait on vblank using cmd ie you don't need to ask the card to emit irq you just insert a cmd in stream which stall further cmd execution until vblank happen, this might be good for power consumption. And will also be nice with app trying to avoid flickering/tearing (mostly movie player). Concern is on application using things like GLX_SGI_video_sync as without using IRQ we likely miss some vblank and thus can't maintain accurate counter, thus maybe this fence vblank stuff might just be an addition to vblank rework you already proposed few weeks ago.
