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 both 1G and 10G NICs on AMD boxes.
