Hi,

Right now, if an atomic commit sends multiple vblank events it is not possible to distiguish for each crtc each event is for in userspace. This series changes that be repurposing the reserved field in struct drm_event_vblank.

Would this be a sane thing to do?

Mostly just needs userspace since atm Weston has a per-crtc draw-loop and doesn't seem to care about events for big modesets. -Daniel
