In fact, we got an engineer sample sometime ago with RD890 chipset

lspci output:

00:00.0 Host bridge: ATI Technologies Inc RD890 Northbridge only dual slot (2x16) PCI-e GFX Hydra part (rev 02)

And i tested VGA passthrough on RD890, not on SR5690/SR5670. And it has IOMMU inside.

Now I'm confused.. so SR5690/SR5670 wasn't tested after all?
Hello, Pasi!

As wikipedia says (http://en.wikipedia.org/wiki/AMD_800_chipset_series) :
The codenames of the chipsets "RD890S", "RD870S" and "SB700S" has also changed to "SR5690", "SR5670" and "SP5100 <http://en.wikipedia.org/wiki/AMD_700_chipset_series#SP5100>".^
Seems, that RD890 and SR5690 are the same chipset with different codenames.

Hello Pasi,

It should have an iommu, but the mobo's are just on the market, haven't tested 
it myself.

Hello Sergey,

Ah if i look at the spec sheets it's not a RD-890 chipset, but a opteron server 

So is RD-890 still ok, aka it has IOMMU support? Has anyone tested it with Xen? Should I remove RD-890 from the wiki pages?

AMD SR5690 + SP5100 (S8212WGM3NR/S8212GM3NR)
AMD SR5670 + SP5100 (S8212GM3NRLE/S8212GM3NR-LE))

Nevertheless good to hear vga passthrough works for you.

Ok so I should add this one.. which one of the various models above is your mb?
