[Qemu-devel] [PATCH] pci: fix requester id with PCI bridges

[Peter Xu]

Recently I encountered issue when debugging Intel IOMMU IR codes,
that interrupts are not working correctly with PCI bridges (reported
by Radim). This patch fixes the problem. I assume requester ID
should be the devfn on root PCI bus (that's how I understand it
before, and also in guest kernel, IRTE entry SID is filled in that
way), however I failed to find any good document to confirm
this. Please let me know if this is correct (or I made any
mistake).

Thanks!
