Thread: Мало доступных режимов процессора

  1. #1

    Default Мало доступных режимов процессора

    В общем такая проблема, гуглинг не дал результатов. У процессора доступны режимы только performance и powersave. Надобно добавить ondemand, но как - непонятно. Вот информация о говернорах и драйвере:
    Code:
    pavel@linux-ov9z:~> cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
    performance powersave
    pavel@linux-ov9z:~> cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
    intel_pstate
    Вывод cat /proc/cpuinfo:

    Не подскажете как добавить новые говерноры? Я так полагаю - надо заменить драйвер, но какой подойдёт? Заранее спасибо.

    Вроде, в ядро зашито поведение процессоров.
    Посмотрите в сторону 'cpupower'.

    Default Re: Мало доступных режимов процессора

    в параметры ядра - intel_pstate=disable
    с acpi_cpufreq появятся остальные governor-ы (регуляторы)...
