- With this option you can enable support for AMD IOMMU hardware in
- your system. An IOMMU is a hardware component which provides
- remapping of DMA memory accesses from devices. With an AMD IOMMU you
- can isolate the DMA memory of different devices and protect the
- system from misbehaving device drivers or hardware.
-
- You can find out if your system has an AMD IOMMU if you look into
- your BIOS for an option to enable it or if you have an IVRS ACPI
- table.
