Subject: [PATCH 0/2] x86/vMSI-X: table read/write emulation adjustments
Date: Fri, 20 Mar 2015 15:52:53 +0000	[thread overview]
Message-ID: <550C5065020000780006C27E@mail.emea.novell.com> (raw)

Due to the (late) point in time when qemu requests the hypervisor to
set up MSI-X interrupts (which is where the MMIO intercept gets put
in place), the hypervisor doesn't see all guest writes, and hence
shouldn't make assumptions on the state the virtual MSI-X resources
are in.

1: honor all mask requests
2: add valid bits for read acceleration
