+``-device virtio-iommu-pci[,option=...]``
+    This is only supported by ``-machine q35`` (x86_64) and ``-machine virt`` (ARM).
+    It supports below options:
+
+    ``granule=val`` (possible values are 4k, 8k, 16k, 64k and host; default: host)
+        This decides the default granule to be be exposed by the
+        virtio-iommu. If host, the granule matches the host page size.
+
+    ``aw-bits=val`` (val between 32 and 64, default depends on machine)
+        This decides the address width of the IOVA address space.
