Subject: [Qemu-devel] [PATCH 15/16] pseries: Fix bug in PCI MSI allocation
Date: Tue, 30 Oct 2012 14:25:11 +1100	[thread overview]
Message-ID: <1351567512-17278-16-git-send-email-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <1351567512-17278-1-git-send-email-david@gibson.dropbear.id.au>

From: Alexey Kardashevskiy <aik@ozlabs.ru>

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.
