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

[Wei Wang2 <wei.wang2@xxxxxxx>]

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.
