Is there any more documentation besides this ?

I'm wondering on the intended usage of this, and its relation
or pros/cons vs other iommu devices

You mention Arm here, but can this virtio-iommu-pci be used on
ppc64, s390x, x86_64 too ?  If so, is it a better choice than
using intel-iommu on x86_64 ?  Anything else that is relevant
for management applications to know about when using this ?

Daniel
