There is no attempt to support vblank interrupts, so this page-flip
implementation does not try to sync the page-flip to vertical blanking,
so expect tearing effects. Is it possible to access the host vblank
intervals in VBOX?
I think it'd be great to move vboxvideo over to atomic instead, which is
required for destaging anyway, and would give you page flip support for
free.

Hi Daniel, yes I agree vboxvideo needs to move to the DRM atomic
framework.
