[RFC 0/3] virtio-iommu: a paravirtualized IOMMU

[RFC 0/3] virtio-iommu: a paravirtualized IOMMU
This is the initial proposal for a paravirtualized IOMMU device using virtio transport. It contains a description of the device, a Linux driver, and a toy implementation in kvmtool. With this prototype, you can translate DMA to guest memory from emulated (virtio), or passed-through (VFIO) devices. In its simplest form, implemented here, the device handles map/unmap requests from the guest. Future
