Subject: [Qemu-devel] [PATCH 11/14] pcnet: use the DMA memory access interface
Date: Fri,  3 Jun 2011 01:12:39 +1000	[thread overview]
Message-ID: <1307027562-3460-12-git-send-email-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <1307027562-3460-1-git-send-email-david@gibson.dropbear.id.au>

This allows the device to work properly with an emulated IOMMU.
