+ bool "VFIO No-IOMMU support"
+ depends on VFIO
+ help
+ 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.
+
+ If you don't know what to do here, say N.
