Subject: [Qemu-devel] [PATCH 07/14] es1370: Use PCI DMA stub functions
Date: Mon, 31 Oct 2011 17:06:51 +1100	[thread overview]
Message-ID: <1320041218-30487-8-git-send-email-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <1320041218-30487-1-git-send-email-david@gibson.dropbear.id.au>

From: Eduard - Gabriel Munteanu <eduard.munteanu@linux360.ro>

This updates the es1370 device emulation to use the explicit PCI DMA
functions, instead of directly calling physical memory access functions.
