Re: [Xen-devel] IOMMU and AMD 890fx
Hello Wei,
I hope motherboard manufacturers do a better job with supporting this iommu in
the bios than they did with intel's. Especially Asus made a mess of it, and
hasn't fixed it in newer bioses for multiple motherboards.
And since all motherboard reviews don't mention nor test the iommu it's hard to
know upfront if it's supported :-(
