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. Regards, Joerg
