Let's just ignore this patch. Sorry for > that confusion. For this part, I'd say of course this is based on the assumption that the IOMMU index might not help much with non-tcg use cases. If someone could help me understand better on how that could help in general to memory API then I would be much appreciated, since it really confused me even until today (and I can't see a good way at least for VT-d to leverage that idea).
