Que signifie machdep.xcpm.cpu_thermal_level ?

Si je devais deviner, je dirais que c'est la quantité d'étranglement qui ralentit votre CPU pour éviter qu'il ne surchauffe sous une charge élevée. Voir le tableau ci-dessous - il n'augmente que d'environ 0 lorsque la température et la charge augmentent :

J'utilise cette commande :

sudo powermetrics --samplers smc | perl -ne 'chomp; print "$_ " if(/:/); print "\n" if(/prochots/)'

afin que vous puissiez voir comment les choses évoluent dans le temps dans un joli tableau - .eg.

Pour compléter l'autre réponse, qui me semble correcte, je peux dire que la partie "xcpm" signifie "XNU CPU Power Management". XNU est le noyau du système d'exploitation d'Apple.

Il est donc certain que la valeur a quelque chose à voir avec la gestion de l'alimentation du processeur - ce qui signifie essentiellement un étranglement.
