[Qemu-devel] [RFC 0/2] Explicit SID for IOAPIC

[David Kiarie]

IOMMU require platform device like IOAPIC and possibly HPET to make
interrupt requests using explicit SIDs which the currently don't.

This patches modify x86 code such that an MSIroute entry is affiliated with 
a requester ID and, if present, a PCI device. This change doesn't seem
have any side effects as far as I can tell.
