[RFC 2/3] virtio-iommu: device probing and operations
...onally read the buffers that were updated by the device. II. Feature bits ================ VIRTIO_IOMMU_F_INPUT_RANGE (0) Available range of virtual addresses is described in input_range VIRTIO_IOMMU_F_IOASID_BITS (1) The number of address spaces supported is described in ioasid_bits VIRTIO_IOMMU_F_MAP_UNMAP (2) Map and unmap requests are available. This is here to allow a device or driver to only implement page-table sharing, once we introduce the feature. Device will be able to only select one of F_MAP_UNMAP or F_PT_SHARING. For the moment, this bit must always be set. VIRTIO_IOMMU_F_BYPASS (3)...
