[PATCH V2 0/3] Passthru device support under emulated amd-iommu |

This patchset adds support for passthru devices to run inside VMs under
the management of an emulated amd-iommu device (vIOMMU). This feature
has a variety of benefits, including enhanced I/O security and user-mode
driver support, for guest VMs.
This patchset has been tested with various 1G and 10G (SR-IOV) NICs on
AMD boxes.
V1->V2:
* Remove unnecessary VFIO_IOMMU_MAP_DMA errno check (Alex Williamson)
Thanks,
-Wei
Wei Huang (3):
amd-iommu: Add address space notifier and replay support
amd-iommu: Sync IOVA-to-GPA translation during page invalidation
amd-iommu: Fix amdvi_mmio_trace() to differentiate MMIO R/W
