Subject: [PATCH v4 0/4] 86/iommu: PVH Dom0 workarounds for missing RMRR entries
Date: Wed, 8 Aug 2018 12:07:43 +0200 [thread overview]
Message-ID: <20180808100747.19464-1-roger.pau@citrix.com> (raw)
Hello,
The following series implement a workaround for missing RMRR
entries for a PVH Dom0. It's based on the iommu_inclusive_mapping VTd
option.
The PVH workaround identity maps all regions marked as reserved in the
memory map.
Note that this workaround is enabled by default on Intel hardware. It's
also available to AMD hardware, although it's disabled by default in
that case.
The series can be found at:
git://xenbits.xen.org/people/royger/xen.git iommu_inclusive_v4
Thanks.
Roger Pau Monne (4):
iommu: introduce dom0-iommu option
iommu: make iommu_inclusive_mapping a suboption of dom0-iommu
dom0/pvh: change the order of the MMCFG initialization
x86/iommu: add reserved dom0-iommu option to map reserved memory
ranges
