Subject: [Qemu-devel] [PATCH 05/10] es1370: Use PCI DMA stub functions
Date: Thu, 1 Sep 2011 15:00:58 +1000 [thread overview]
Message-ID: <1314853263-2086-6-git-send-email-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <1314853263-2086-1-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.
