I'm not going to lie, I was really hoping the 5th (?) GPU option for
Qemu would support pageflipping. Daniel's comment about conversion to
atomic is relevant, but: do you have a mechanism which allows you to
post updates (e.g. 'start displaying this buffer now please') that
allows you to get events back when they have actually been displayed?
Cheers,
