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, Daniel
