Subject: [09/18] virtio: set pci bus master enable bit
Date: Fri, 04 Mar 2011 17:03:03 -0800 [thread overview]
Message-ID: <20110305010352.690887944@clark.kroah.org> (raw)
In-Reply-To: <20110305010410.GA18668@kroah.com>
2.6.32-longterm review patch. If anyone has any objections, please let us know.
------------------
From: Michael S. Tsirkin <mst@redhat.com>
commit bc505f373979692d51a86d40925f77a8b09d17b9 upstream.
As all virtio devices perform DMA, we
must enable bus mastering for them to be
spec compliant.
This patch fixes hotplug of virtio devices
with Linux guests and qemu 0.11-0.12.
