So you chose GSI == 0 as invalid because of x86 assumptions? Or is there
any other reason?
Yeah, it based on x86 and IA64 IRQ 0 can't be used by MSI-X. And only x86
support MSI-X now(and IA64 would follow later).
gsi != irq... as used in kvm it is just a cookie and is never visible to
the guest. I'd prefer an illegal value here.
Also, please repost the entire patchset so I can be sure I apply the
latest; too many versions floating around.
