Hi, So after talking to a few people at kvm forum I think the GPU code should probably use the dataplane stuff from the outset,
The main advantages I think this gives me is being able to dequeue objects from the vq from a thread and send irq vectors from there as well. Though since it appears the dataplane stuff is kvm specific (at least the irq handling), I was wondering how I should deal with fallbacks for non-kvm operation, and quite how much falling back I need to do. Can I still use the dataplane/vring code from the normal bottom half handlers or do I have to write separate code for both situations. Dave.
