[Qemu-devel] [PATCH 10/10] intel-hda: Use PCI DMA stub functions


From: David Gibson
Subject: [Qemu-devel] [PATCH 10/10] intel-hda: Use PCI DMA stub functions
Date: Thu, 1 Sep 2011 15:01:03 +1000

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