	  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.

	---help---
	  This option enables code in the AMD IOMMU driver to collect various
	  statistics about whats happening in the driver and exports that
