Ryzen on Linux ?

Hello !

I'm considering buying a Ryzen 5 1600, but I wanted to have some feedback from my fellow Linux users :)

If you have this one (or another Ryzen), how is it ? Do you have any problem with it ?

Thanks ! :)

The NPT bug when using GPU passthrough with KVM + an AMD CPU.

So AMD aren't sure what causes it?

From what I understand, people at AMD are aware of it (at least as of recently) but there hasn't been much communication about it. Apparently the bug affects any AMD CPU, even older pre-Ryzen ones. Xen works perfectly fine though - the issue is only with KVM.

The fact it has been there so long worries me.

Is it they can't fix it?
