Again the event can only be sent out after the * hardware has stopped scanning out the old buffers. * * - Events for disabled CRTCs are not allowed, and drivers can ignore * that case. * * This can be handled by the drm_crtc_send_vblank_event() function, * which the driver should call on the provided event upon completion of * the atomic commit.

See the documentation of that function * for a detailed discussion of the constraints it needs to be used * safely. * * If the device can't notify of flip completion in a race-free way * at all, then the event should be armed just after the page flip is * committed.
