[Xen-devel] [PATCH] AMD IOMMU: add support for PV guest



Attached patch enables AMD IOMMU for PV guest. It has been tested with
PV guest being configured as both passthru domain and backend domain.
Assuming
iommu_populate_page_table() is only used for PV guest, a new check is
added into assign_device() to avoid duplicating the work done by
amd_iommu_sync_p2m() for hvm guest.
