[Xen-devel] [PATCH v7 0/7] Paravirtual IOMMU Interface

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

This contains the remaining patches from my original PV-IOMMU series (that
were not included in the recent pre-requisites series), and some new
patches to support the revised implementation.

The new patches are:
 - To add a 'no crash' variant of the internal IOMMU map method.
 - To add a new 'refcount' bit into the VT-d IOMMU PTE.

I have started this series at v7 as it derives from v6 of the old series.

Paul Durrant (7):
  public / x86: introduce __HYPERCALL_iommu_op
  iommu: track reserved ranges using a rangeset
  x86: add xen_iommu_op to query reserved ranges
  iommu: introduce iommu_map_page_nocrash
  iommu / vtd: introduce a new 'refcount' flag...
  x86: add xen_iommu_ops to modify IOMMU mappings
  x86: extend the map and unmap xen_iommu_ops to support grant
