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.
