The following series implements QEMU device assignment using the
proposed VFIO/UIOMMU kernel interfaces. See the last patch for
further vfio description. I've tested this on the v2 VFIO patch,
with a number of fixes hacked in along the way. I'll update when
Tom releases a new version of VFIO. Hopefully this will provide
some support for the usefulness of such an interfaces. Thanks,
Alex
