Just to be clear, does this solve the issues with GPU passthrough in virtualization environments (i.e. KVM)?

  It seems like it will help if your motherboard doesn't already have convenient IOMMU groupings. There's nothing to indicate that this will help with the NPT issue, so expect poor performance (CPU or GPU, your choice).

    What is the NPT issue?

      I posted about it below: https://news.ycombinator.com/item?id=14427098 https://news.ycombinator.com/item?id=14427098 There's also a thread on the vfio-users mailing list and on a few other mailing lists as well as some discussion on /r/vfio.

  I don't think this address passthrough in any way whatsoever.
