September 10, 2020 — Leave a comment. Want to change CPU frequency scaling in Ubuntu 20.04? Board: rpi2 Kernel: rpi-4.7.y built with bcm2709_defconfig, no changes to kernel .config were made. cpupower: built from rpi-4.7.y tree https: I have an openmp "hello world" program. I have set "performance" governor with cpupower (old cpu-freq) to every core (because I have intel_pstate module). While I run VTune, I execute: sudo cpupower --cpu all frequency-info | grep 'CPU freq' to check the frequencies.

I have a server HPE ProLiant system with AMD Epyc CPU, BIOS A43 v1.20, with Linux kernel 4.19.71 (as well I tried on 5.4.0). Now, I'm trying to set CPU performance governor: # cpupower frequency-se [root@Laptop wudu]# cpupower frequency-set -u 875000 Setting cpu: 0 [root@Laptop wudu]# cpupower frequency-info analyzing CPU 0: driver: p4-clockmod CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.00 ms. How to modify single core configurations is described in the cpupower(1) manpage in the --cpu option section.

Thus, power management is always a matter of balancing the actual performance needs and power saving options for a system. Power management can be implemented and used at different levels of the system.

To permanently change the setting create a custom systemd service with the required settings, for example: 1. $ cpupower frequency-info Setting maximum and minimum frequencies. In some cases, it may be necessary to manually set maximum and minimum frequencies. To set the maximum clock frequency (clock_freq is a clock frequency with units: GHz, MHz): # cpupower frequency-set -u clock_freq. To set the minimum clock frequency: # cpupower frequency-set -d clock_freq To choose userspace as the CPU governor and scale the frequency, run the following commands: $ sudo cpupower frequency- set -g userspace $ sudo cpupower frequency- set -f 1400 MHz The input unit for the frequency can be Hz, MHz and GHz. Your CPU should now running at your desired speed. For cpupower frequency-set, the following options are available: --min and --max — Set the policy limits of the CPU, in KHz. Important When setting policy limits, you --freq — Set a specific clock speed for the CPU, in KHz. You can only set a speed within the policy limits of cpupower is a collection of tools to examine and tune power saving related features of your processor. The manpages of the commands (cpupower-(1)) provide detailed descriptions of supported features.
