Right. kvm in kernel has this as well, we need to keep this in
kvm kernel if we want to support level with irqfd.
Right, we added the irq_source_id hack for device assignment.
What's wrong with letting userspace mediate this, though?
Where it does not belong is individual devices: these
should be able to assert INTx multiple times
and it should have no effect, as per spec.
Yes.
