i like to set up a Desktop PC based on the AMD FX-8120 using IOMMU for the direct use of my Graphics Card (HD 7870) within the guest system in a VM (VGA Passthorugh) using Linux as host OS.
Because I can't find any definite information on the IOMMU compatiblity of my preferred mainboard (Gigabyte GA-970A-UD3) I thought of asking you.

If you don't know too, can you advice me a mainboard having the specs like the one I chose supporting IOMMU?
Is there a global rule what models/chipsets support IOMMU? (read of 970 and 990 chipsets having support)
Is IOMMU support directly connected to the ability to setup IOMMU in BIOS?

Do I have to be aware of the GPU being compatible with IOMMU, too?

Thank you very much!

I would download that motherboards manual and do a search for IOMMU in there to see if there is any reference. I do remember seeing IOMMU listed in the BIOS of either my Crosshair IV Formula or my Crosshair V Formula as a enable/disable feature setting so you may want to look there.
