Are you using, for example, CUDA for HPC workload on Linuxulator?

For use-cases on native FreeBSD environment, nvidia GPUs are used really for
"Graphics" Processing Unit, regardless xorg or Wayland.

In these cases, persistence mode should NOT be needed, as GPUs are always up
and running at least if nvidia GPUs are the primary GPU configured.
And on hybrid graphics with iGPU is the primary (Optimus), I think persistence
mode is not so important, as iGPU should be working even on nvidia dGPU is on
startup.

For HPC on Liuxulator case, x11/linux-nvidia-libs has nvidia-persistenced.
