[PATCH v3 0/6] Add virtio-iommu built-in topology
Add a topology description to the virtio-iommu driver and enable x86
platforms.
Since [v2] we have made some progress on adding ACPI support for
virtio-iommu, which is the preferred boot method on x86. It will be a
new vendor-agnostic table describing para-virtual topologies in a
minimal format. However some platforms don't use either ACPI or DT for
booting (for example microvm), and will
