Subject: [PATCH 0/3] Fix grant map/unmap with auto-translated guests
Date: Mon, 7 Apr 2014 18:02:01 +0200 [thread overview]
Message-ID: <1396886524-16921-1-git-send-email-roger.pau@citrix.com> (raw)
This series adds proper IOMMU entries when performing grant
mapping/unmapping inside of auto-translated guests when the p2m is not
shared between HAP and IOMMUs, and disables p2m sharing when running
on AMD hardware.
In order for the guest to know if it's safe to use grant mapped pages
for IO with hardware devices a new xen feature is introduced in the
last patch.
[PATCH 1/3] iommu: set correct IOMMU entries when iommu_hap_pt_share
[PATCH 2/3] amd-iommu: disable iommu_hap_pt_share with AMD IOMMUs
[PATCH 3/3] xen: expose that grant table mappings update the IOMMU
