[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.
