| 37 | help | |
| 38 | VFIO is built on the ability to isolate devices using the IOMMU. | |
| 39 | Only with an IOMMU can userspace access to DMA capable devices be | |
| 40 | considered secure. VFIO No-IOMMU mode enables IOMMU groups for | |
| 41 | devices without IOMMU backing for the purpose of re-using the VFIO | |
| 42 | infrastructure in a non-secure mode. Use of this mode will result | |
| 43 | in an unsupportable kernel and will therefore taint the kernel. | |
| 44 | Device assignment to virtual machines is also not possible with | |
| 45 | this mode since there is no IOMMU to provide DMA translation. | |
