Hi Gerd,

The vfio bits look reasonable to me, it'd be nice if we could operate
on the VFIODevice rather than VFIOPCIDevice to make this universal for
all vfio devices, but that's just a nit since non-PCI graphics devices
may never come to fruition.  As for testing, region support was
included for NVIDIA, dmabuf for Intel... is this testing request mainly
for the Kirti and others at NVIDIA?  Thanks,

Alex
