There seem to be a lot of commits and discussion about VT-d support, however there seems to be very little activity regarding device passthrough using the AMD IOMMU. Is it "done", lacking a mantainer, or never going to work? A quick google showed that 8 series chipsets for desktop are likely to be released very soon (looks like it is only the 8 series that have the relevant IOMMU). I''m not sure if any other hardware is required for passthrough, does anyone know if there is anything special about the CPU? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
AMD are actively working on it. Most recent committed patch specifically for AMD IOMMU support was mid December. -- Keir On 08/01/2010 00:10, "Andrew Oakley" <andrew@ado.is-a-geek.net> wrote:> There seem to be a lot of commits and discussion about VT-d support, > however there seems to be very little activity regarding device > passthrough using the AMD IOMMU.

Xen''s support for AMD IOMMU is up-to-date. You need 800 chipset and a working BIOS to use IOMMU. There will be an option in BIOS to turn it on/off. IOMMU feature doesn''t require special support from CPUs. Best, -Wei Keir Fraser wrote:> AMD are actively working on it.
