Subject: [PATCH 01/20] xen: Don't disable the I/O space
Date: Wed,  4 Aug 2010 14:18:56 -0400	[thread overview]
Message-ID: <1280945955-14229-2-git-send-email-konrad.wilk@oracle.com> (raw)
In-Reply-To: <1280945955-14229-1-git-send-email-konrad.wilk@oracle.com>

From: Alex Nixon <alex.nixon@citrix.com>

If a guest domain wants to access PCI devices through the frontend
driver (coming later in the patch series), it will need access to the
I/O space.

[ Impact: Allow for domU IO access, preparing for pci passthrough ]
