It may have an IOMMU, but does Xen 4.6 work properly with it? Someone

Of course why wouldn't it?
The issue with desktops is that the OEM's fail to properly implement it
in their proprietary firmware as to differentiate their server
motherboard lines.
Who said that anyway?
A couple references I can recall:

Don't know how much of this is firmware or other factors...
That is ryzen, a new platform not bulldozer.
As usual the OEM's have failed to properly implement it in their desktop
boards.
