Subject: [Qemu-devel] [RFC PATCH 10/13] lsi53c895a: use the DMA memory access interface
Date: Wed,  1 Jun 2011 04:38:32 +0300	[thread overview]
Message-ID: <1306892315-7306-11-git-send-email-eduard.munteanu@linux360.ro> (raw)
In-Reply-To: <1306892315-7306-1-git-send-email-eduard.munteanu@linux360.ro>

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