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

Implement the virtio-iommu driver, following specification v0.12 [1]. Since last version [2] we've worked on improving the specification, which resulted in the following changes to the interface: * Remove the EXEC flag. * Add feature bit for the MMIO flag. * Change domain_bits to domain_range. Given that there were small changes to patch 5/7, I removed the review and test tags. Please find

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
