This bug exist much long time, there are many discussion last year but not a
solution then. I call out it now because there is a fix in qemu upstream:
commit a8036336609d2e184fc3543a4c439c0ba7d7f3a2
Author: Roger Pau Monne <roger....@citrix.com>
Date: Thu Aug 24 16:07:03 2017 +0100
xen/pt: allow QEMU to request MSI unmasking at bind time
The fix is not in qemu-xen tree yet, when will qemu-xen sync this fix? Is it
possible to catch Xen 4.10's qemu-xen?
I will let Stefano and Anthony providing feedback before giving a release-ack
here.
Yes, I think we should backport the commit as it fixes a genuine bug.
The backport is not risk-free but it only affects PCI Passthrough. Also
the commit has been in QEMU for 2 months now.
Does anyone actually tested it with QEMU Xen tree?
Yes. I've tested qemu-xen with this patch and PCI passthrough still
works.
Can I get a release-ack?
I'd still like an answer on Roger's question whether this patch fixes
the issue they met.
Cheers,
