Yes, I think the next step is that someone who read the whole thread
writes up the conclusions and a rough /dev/ioasid API proposal, also
mentioning the use-cases it addresses. Based on that we can discuss the
implications this needs to have for IOMMU-API and code.

From the use-cases I know the mdev concept is just fine. But if there is
a more generic one we can talk about it.
