Besoin aide pour config cpufrequtils

Support Debian
#1

Bonjour à tous.
Je m’y connais pas grand chose sur cpufrequtils.
J’ai compilé un noyau récent (de chez kernel.org) avec comme paramètre cpufrequtils en mode par défaut “performance”, les autres mode sont coché en module.

Je boot sur ce noyau et tape: cpufreq-info

cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to cpufreq@vger.kernel.org, please. analyzing CPU 0: no or unknown cpufreq driver is active on this CPU maximum transition latency: 0.00 ms. analyzing CPU 1: no or unknown cpufreq driver is active on this CPU maximum transition latency: 0.00 ms. analyzing CPU 2: no or unknown cpufreq driver is active on this CPU maximum transition latency: 0.00 ms. analyzing CPU 3: no or unknown cpufreq driver is active on this CPU maximum transition latency: 0.00 ms.

Par défaut dans /etc/default/cpufrequtils, j’ai:
GOVERNOR=“conservative”

Je fais:
service cpufrequtils stop
service cpufrequtils start

Ça me renvoi:
[ ok ] CPUFreq Utilities: Setting conservative CPUFreq governor…disabled, governor not available…done.

Je met en mode performance:
GOVERNOR=“performance”

Je fais:
service cpufrequtils stop
service cpufrequtils start

Ça me renvoi:
[ ok ] CPUFreq Utilities: Setting performance CPUFreq governor…disabled, governor not available…done.

J’aimerais faire fonctionner les différents mode, merci d’avance de votre aide.

Salut,

Et si pour résoudre ce problème qui vient soit de cpu, soit du kernel fraîchement compilé, tu utilisais la dichotomie.
Tu pars d’un noyau fourni par le réseau Debian et tu essaies de maîtriser cpufrequtils. Puis tu passes au kernel compilé ?

#3

J’essaiyerais.

#4

J’ai essayé le noyau debian, pas marcher.

C’était donc un soucis de cpu, dans le bios j’ai du mettre en “enable” les réglages concernant le cpu, je sais pas c’est lequel il y en a 4 faudra essayer un par un.
Je les avais désactiver pour que les fréquences ne soit pas diminué-augmenté automatiquement.

La mauvaise nouvelle, j’ai mon cpu en overclocking à 4.00 GHz, je me demande s’il va prendre en compte.

Une autre nouvelle…sur les derniers kernels, cpufrequtils est deprecated, cad obsolète et devenu inutile.

#6

wiki archlinux:
“Important: cpufrequtils est déprécié et il est remplacé par cpupower. Ce dernier ajoute également des fonctionnalités.”

À trouver dans debian “cpupower”.
