Overall looks pretty good !

I think we'll move to propre enum SYSTEM instead of IS_XXXX since there's no way a user could be running 2 devices simultaneously. But we'll take care of that in a subsequent PR if that's OK.

@Narsil @OlivierDehaene I add xpu smi in env runtime, do you think is it proper to add this? this is to dump intel XPU version.

It's OK in the current iteration (since showing N/A on most systems).
