How does a userspace program receive those interrupts?
Same as other UIO drivers - by read()ing an event counter.

IIRC the usual event counter is /dev/uioX, what's your event counter now?

kvm really wants the event counter to be an eventfd, that allows hooking it directly to kvm (which can inject an interrupt on an eventfd_signal), can you adapt your patch to do this?
