-	  VFIO is built on the ability to isolate devices using the IOMMU.
-	  Only with an IOMMU can userspace access to DMA capable devices be
-	  considered secure.  VFIO No-IOMMU mode enables IOMMU groups for
-	  devices without IOMMU backing for the purpose of re-using the VFIO
-	  infrastructure in a non-secure mode.  Use of this mode will result
-	  in an unsupportable kernel and will therefore taint the kernel.
-	  Device assignment to virtual machines is also not possible with
-	  this mode since there is no IOMMU to provide DMA translation.
