У меня есть
Processor Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz
Memory 16305MB (2531MB used)
Machine Type Laptop
Operating System Ubuntu 20.04.3 LTS
В моем / etc / default / grub файле есть строка
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=enable"
Я выполнил sudo update-grub после изменений но когда я делаю cpupower frequency-info или cpufreq-info --driver он говорит, что используемый драйвер - intel_cpufreq
rt@sys76:~$ cpufreq-info --driver
intel_cpufreq
rt@sys76:~$ cpupower frequency-info
analyzing CPU 0:
driver: intel_cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 20.0 us
hardware limits: 800 MHz - 3.40 GHz
available cpufreq governors: conservative ondemand userspace powersave performance schedutil
current policy: frequency should be within 1.70 GHz and 3.40 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 798 MHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: yes
rt@sys76:~$
Как я могу получить cpufreq-info --driver использовать драйвер intel_pstate ?
