Subject: [PATCH v4 0/4] Fix grant/foreign mappings with auto-translated guests
Date: Wed, 4 Jun 2014 12:06:17 +0200 [thread overview]
Message-ID: <1401876381-42977-1-git-send-email-roger.pau@citrix.com> (raw)
This series adds proper IOMMU entries when mapping foreign memory
(either grants or foreign pages) 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 cpuid feature is introduced in
the last patch.
Thanks for the review, Roger.
