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.
