Another gap I believe we need to close is that we need some instructions in the GSG for using vfio in noiommu mode, for those running in VMs without an emulated iommu. The VM case is the big one where using regular VFIO may cause problems. I do see in the GSG one mention that it's possible to use VFIO without an IOMMU, but no instructions on how to do so. /Bruce
