The reverse is also true I believe: you can have two devices with different physical IRQs getting aliased to the same guest GSI. Is that a problem? e.g., do you need the reverse mapping from guest GSI to physical IRQ or physical device (I'd guess you do, to work out what to do when the guest GSI is EOIed)? > What's more, we need to deal with > intra-domain shared interrupt injection and eoi specially.
