В биосе ”Performance Boost” установлен в disabled.
Как это здесь отключить если это возможно?
$ cpupower frequency-info analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 4.0 us. hardware limits: 1.40 GHz - 3.60 GHz available frequency steps: 3.60 GHz, 3.30 GHz, 2.70 GHz, 2.10 GHz, 1.40 GHz available cpufreq governors: ondemand, performance, schedutil current policy: frequency should be within 1.40 GHz and 3.60 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 1.40 GHz. cpufreq stats: 3.60 GHz:2,85%, 3.30 GHz:0,99%, 2.70 GHz:2,88%, 2.10 GHz:9,54%, 1.40 GHz:83,74% (36143) boost state support: Supported: yes Active: yes
Это работает только до перезагрузки

Есть какой-нибудь простой способ?

#cpupower frequency-set -g powersave
А для постоянки - отредактировать файл /etc/conf.d/cpupower
