This talk will cover the software implementation details of AMD hardware-assisted vIOMMU (HW-vIOMMU), which includes the QEMU HW-vIOMMU device model, the extension to AMD IOMMU driver to support the new HW-vIOMMU capability in the hypervisor, and the guest I/O page table support for DMA-API in the guest kernel. The talk will also demonstrate passing-thru of a PCI device, which will be managed by the HW-vIOMMU inside the VM, and will also analyze performance data of the HW-vIOMMU in various aspects, as well as discuss future improvements.
