Exactly. The INTR really just

Both the vcpu and the irqdevice are involved in the decision:

I wasn't planning on the irqdevice having this type of control because I
assumed we would always have these exit types set, but you have highlighted
an interesting point. If we

Hi All,
The following is another patch that I broke out of the in-kernel-apic patch
that I sent earlier. This focuses purely on the irqdevice abstraction without
introducing the concept of the in-kernel LAPIC. It also provides an
implementation of a userint model, which should support a
