Hi Alok, Joining this a bit late as this was just brought to my attention. It would have been nice to CC the virtualization mailing list. Please do in future submissions.

Below should be useful for some experiments Jason is doing. I thought I'd send it out for early review/feedback. event idx feature allows us to defer interrupts until a specific # of descriptors were used. Sometimes it might be useful to get an interrupt after a specific descriptor, regardless. This adds a descriptor flag for this, and an API to create an urgent output descriptor. This is

For virtualization, we've developed virtio_ring for efficient communication. This would also work well for userspace-kernel communication, particularly for things like the tun device. By using the same ABI, we can join guests to the host kernel trivially. These patches are fairly alpha; I've seen some network stalls I have to track down and there are some fixmes. Comments welcome!
