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

Posted by Wei Huang 3 years, 7 months ago

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
