Limetech thoughts on NPT issues with Ryzen?


Recommended Posts

Hello

 

I have been reading many reports from various sources regarding the NPT issue with Ryzen and GPU passthrough. Many (including myself) are frustrated with the poor GPU/CPU performance exhibited in either ntp=0 or npt=1 modes.  No-one from Linux KVM dev teams from what I can tell has acknowledged there is an issue and that it is being looked at, this is extremely worrying especially with Threadripper just around the corner.

 

I would be interested to hear the techie's thoughts from Limetech regarding this problem. Maybe someone has good connections in the KVM dev community and can possibly give us a positive update on this problem? I'm sure the UNRAID faithful would welcome some update/news either way.

 

Thank you.
