[vfio-users] NPT Performance Bug Identified and Fixed

[Nick Sarnie]

Hi all,

I just wanted to send an update if you haven't heard. The cause of the
bad GPU performance with NPT enabled on AMD systems has been
identified and fixed.

The patch is located here: https://patchwork.kernel.org/patch/10027525/

I assume it will make it upstream soon. For now, you have to patch your kernel.

Thanks to Geoff and Paolo for their great work.
