[RFC 3/3] virtio-iommu: future work
...e MAP/UNMAP API. The driver intends
to manage the address space itself.
(2) Driver sends a PROBE_TABLE request. It sets len > 0 with the size of
pg_format array.

le32 flags;

Introducing a probe request is more flexible than advertising those
features in virtio config, because capabilities are dynamic, and depend on
which devices are attached to an address space. Within a single address
space, devices...

[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
