[RFC 00/13] virtio-iommu on non-devicetree platforms
I'm seeking feedback on multi-platform support for virtio-iommu. At the moment only devicetree (DT) is supported and we don't have a pleasant solution for other platforms. Once we figure out the topology description, x86 support is trivial. Since the IOMMU manages memory accesses from other devices, the guest kernel needs to initialize the IOMMU before endpoints start issuing DMA.
