...frastructure is > able to deal with multiple DMA configuration methods. Urgh, it's already been established[1] that having IOMMU setup tied to DMA configuration at driver probe time is not just conceptually wrong but actually broken, so the concept here worries me a bit. In a world where of_iommu_configure() and friends are being called much earlier around iommu_probe_device() time, how badly will this fall apart? Robin.

Add topology description to the virtio-iommu driver and enable x86 platforms. Since the RFC [1] I've mostly given up on ACPI tables, since the internal discussions seem to have reached a dead end. The built-in topology description presented here isn't ideal, but it is simple to implement and doesn't impose a dependency on ACPI or device-tree, which can be beneficial to lightweight
