[Qemu-devel] [RFC PATCH 0/5] QEMU VFIO device assignment

[Alex Williamson]

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
