[Xen-devel] [PATCH 0/4] x86/iommu: PVH Dom0 workarounds for missing RMRR/IRSV entries

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

Hello,

The following series implement a workaround for missing RMRR/IRSV
entries for a PVH Dom0. It's based on the iommu_inclusive_mapping VTd
option, which is generalized to be used by both VTd and AMD-Vi
hardware.

The PVH workaround identity maps all regions marked as reserved in the
memory map.

The series can be found at:

git://xenbits.xen.org/people/royger/xen.git iommu_inclusive_v1

Thanks, Roger.

Roger Pau Monne (4):
  iommu: remove unneeded return from iommu_hwdom_init
  iommu: generalize iommu_inclusive_mapping
  x86/iommu: reorder conditions used in the inclusive iommu mappings
  x86/iommu: add PVH support to the inclusive options
