There is limited CUDA support w/in the linux emulation layer for nvidia/cuda, but the native nvidia blob for FreeBSD hasn't had this support for well over the ~20 years (or more) I've been using FreeBSD. That's an important distinction. Also, it's maybe true that they've added support within the past year to the native blob, but when I was building my machine not than a year ago, it wasn't there. ~Paul On Sun, Feb 7, 2021 at 2:13 AM Paul Procacci wrote: > It's not incorrect.
