Subject: [PATCH 0 of 2] Support for Paging/Sharing on AMD
Date: Tue, 27 Mar 2012 11:43:26 -0400 [thread overview]
Message-ID: <patchbomb.1332863006@xdev.gridcentric.ca> (raw)
This is a partial repost of the series first sent on Mar 22nd.
It currently contains two patches
- Teach paging types to p2m-pt.
- Add interlock for iommu and mem paging/sharing.
The first patch is rebased to apply on top of
http://lists.xen.org/archives/html/xen-devel/2012-03/msg01982.html
and addresses some feedbackfrom Tim Deegan.
The second patch prevents a passthrough device from being assigned to a domain
if mem paging or sharing have been turned on. And viceversa. This is a missing
check that is necessary for both Intel and AMD processors.
