With the built-in topology description in place, x86 platforms can now use the virtio-iommu. Architectures that use the generic iommu_dma_ops should normally select CONFIG_IOMMU_DMA themselves (from arch/*/Kconfig). Since not all x86 drivers have been converted yet, it's currently up to the IOMMU Kconfig to select it.
