	  Select this to get support for AMD IOMMU hardware in your system.

	  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 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.
