[Xen-devel] [PATCH v2 0/2] VT-d: make dom0-strict work with buggy firmware

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

When dom0-strict mode is enabled the iommu_inclusive_mapping workaround
for firmware with undeclared RMRRs is rendered useless. This series fixes
the problem.

Paul Durrant (2):
  VT-d: re-phrase logic in vtd_set_hwdom_mapping() for clarity
  VT-d: reconcile iommu_inclusive_mapping and iommu=dom0-strict
