[РЕШЕНО] Перестал работать cpupower

Заработал второй способ.

1-ый тоже должен был сработать - нужно было смотреть scaling_max_freq

# cpupower frequency-set -u 1100000
Setting cpu: 0
Setting cpu: 1
Setting cpu: 2
Setting cpu: 3
# cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq
1100000
1100000
1100000
1100000

Но, конечно, 2-ой проще, не нужно отключать intel_pstate , если он у тебя стоит и если он тебя устраивает ...

~>s modprobe cpufreq_userspace
~>sudo cpupower frequency-set --governor userspace
~>s cpupower frequency-set -u 1100000
~>s cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq
2301000
2301000
2301000
2301000
2301000
2301000
2301000

~>s 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: 10.0 us
  hardware limits: 1.20 GHz - 2.30 GHz
  available frequency steps:  2.30 GHz, 2.30 GHz, 2.20 GHz, 2.10 GHz, 2.00 GHz, 1.90 GHz, 1.80 GHz, 1.70 GHz, 1.60 GHz, 1.50 GHz, 1.40 GHz, 1.30 GHz, 1.20 GHz
  available cpufreq governors: userspace ondemand performance
  current policy: frequency should be within 1.20 GHz and 2.30 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency: 1.20 GHz (asserted by call to hardware)
  boost state support:
    Supported: yes
    Active: yes

    3100 MHz max turbo 3 active cores
    3200 MHz max turbo 2 active cores
    3300 MHz max turbo 1 active cores

Почему-то первый не хочет работать
