Okay, let me know, I can possibly help make parts of this happen power is the last still-current architecture to be outside the modern IOMMU and DMA API design and I'm going to start proposing things that will not be efficient on power because of this. I think a basic iommu driver using the dma API would not be so hard. I don't know what to do about the SPAPR VFIO mess though. :( Jason
