cpufreq support pour AMD 5350 sur Ubuntu 17.04?
Sur Debian 8, j’ai pu configurer le gouverneur cpu sur un petit ordinateur doté d’un processeur AMD 5350 apu (kabini cpu).
en utilisant maintenant Ubuntu 17.04, noyau 4.10, je reçois:
no or unknown cpufreq driver is active on this CPU
Des idées pourquoi?
