IOW, you enter the BIOS, go to "NB settings" or similar and set IOMMU
to Auto/Enabled. Provided you have an IOMMU but you should have that on
this chipset.
Then, you enable CONFIG_AMD_IOMMU in your kernel and done: the kernel
uses the IOMMU hardware instead of the GART.
That's it, no need for any BIOS up-/downgrading.
