RE: [Xen-devel] IOMMU and AMD 890fx



I can confirm that AMD 890FX supports IOMMU v1.22. It was briefly mentioned by external sites, such as http://techreport.com/articles.x/18825. It looks like Asus, Gigabyte and MSI will ship motherboards with 890FX chipset. Xen 4.0 fully supports AMD IOMMU v1.2. Note that IOMMU needs support from BIOS (ACPI IVRS table). Please pay a bit attention to this area.

All the reviews for the AMD 890fx chipset reported that it supports IOMMU v1.2.
But I cannot find any mention of that on AMD site.

Does 890fx support IOMMU?
Do 890fx motherboards with IOMMU exist?
Does Xen support 890fx?
