Subject: [Qemu-devel] [PATCH] pci: fix requester id with PCI bridges
Date: Wed, 11 May 2016 14:40:30 +0800 [thread overview]
Message-ID: <1462948831-931-1-git-send-email-peterx@redhat.com> (raw)
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!
