Subject: [PATCH V2 0/3] Passthru device support under emulated amd-iommu
Date: Fri, 2 Oct 2020 09:59:04 -0500 [thread overview]
Message-ID: <20201002145907.1294353-1-wei.huang2@amd.com> (raw)
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
