[Xen-devel] [PATCH v2 0/5] x86/iommu: PVH Dom0 workarounds for missing RMRR entries

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

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_v2

Thanks, Roger.

Roger Pau Monne (5):
  iommu/vtd: cleanup vtd_set_hwdom_mapping after ia64 removal
  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 PVH support to the inclusive options
