Looking good. Wrt pageflip the current MO is to handroll it in your
driver, common approach is to use the msm async commit implementation
msm_atomic_commit. The issue is simply that right now there's still no
useable generic vblank callback support (drm_irq.c is a mess) hence why
the core helpers don't support async flips yet.
