[Qemu-devel] [PATCH 11/12] pseries: Fix bug in PCI MSI allocation


From: David Gibson
Subject: [Qemu-devel] [PATCH 11/12] pseries: Fix bug in PCI MSI allocation
Date: Tue, 13 Nov 2012 13:46:59 +1100

From: Alexey Kardashevskiy <address@hidden>

In one of the recent reworks to the XICS code, a bug was introduced where
we use the wrong sense and allocate level interrupts instead of message
interrupts for PCI MSIs.  This patch fixes it.
