IOMMU/AMD-Vi support on boards with AMD 9-series chipsets

[cjn]

Hi,

According to this page, all AMD 9-series chipsets support IOMMU/AMD-Vi but "the bios must have a ACPI IVRS table to enable the use of it!". So, which of the following boards with an AMD 9-series chipset have this "ACPI IVRS" table and support IOMMU/AMD-Vi?

AMD 990FX chipset:

• Fatal1ty 990FX Professional
• 990FX Extreme4
• 990FX Extreme3

AMD 970 chipset:

• 970 Extreme4
• 970 Extreme3
• 970 Pro3

I'll take any confirmation of working IOMMU/AMD-Vi support, unofficial as well as official, so please contribute your experiences. Thanks!

I have the 990 FX Extreme4 and have been having trouble enabling "Lazy IO/TLB flushing" on my 1100T. It may not be present on the BIOS. I was very much hoping to do PCIe passthrough to a VM for native Windows 7 Gaming on my linux host but this may prevent me from doing so. I will try a BIOS update this week and see if that makes any difference.

I want to do exactly the same thing. I've been eyeing the "990FX Extreme3" board and intend to stick either a Piledriver or a Steamroller CPU on it (whichever performs satisfactorily), but I don't want to buy anything before I know that it'll work. Please keep us updated!
