This matches the v0.12 spec (voted) and the corresponding virtio-iommu driver upstreamed in 5.3. All kernel dependencies are resolved for DT integration. The virtio-iommu can be instantiated in ARM virt using: "-device virtio-iommu-pci". Non DT mode is not yet supported as it has non resolved kernel dependencies [1]. This feature targets 5.0. Integration with vhost devices and vfio devices is not part of this series. Please follow Bharat's respins [2].
