I have already read similar posts about this but none of them is related to my situation.

When using the following command :

cpupower frequency-info

I get the following result :

analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU
  CPUs which run at the same hardware frequency: Not Available
  CPUs which need to have their frequency coordinated by software: Not Available
  maximum transition latency:  Cannot determine or is not supported.
Not Available
  available cpufreq governors: Not Available
  Unable to determine current policy
  current CPU frequency: Unable to call hardware
  current CPU frequency:  Unable to call to kernel
  boost state support:
    Supported: no
    Active: no

It says

no or unknown cpufreq driver is active on this CPU

I read that I need to enable Intel turbo, but I don't have the following file /sys/devices/system/cpu/intel_pstate/no_turbo.

How can I set CPU governor to performance in my Ubuntu 22 server?
I have 8 cores of CPU .

EDIT: My kernel version is 5.15.0-94-generic and the output of cat /proc/cpuinfo ; find /sys/devices/system/cpu can be found here at PasteBin.

  • cpupower requires root access. Please [edit] your question and show us the output of sudo cpupower frequency-info instead. – terdon Feb 19 '24 at 16:56
  • @terdon I ran the command as root . the output is the same . – lostsoul6 Feb 19 '24 at 17:09
  • Does this answer your question? How to set as default Performance mode on Ubuntu 20.04 instead of Powersave? – WinEunuuchs2Unix Feb 19 '24 at 17:57
  • @WinEunuuchs2Unix No because he wants to change governor from powersave to performance but I don't even have those enabled and I get : no or unknown cpufreq driver is active on this CPU . don't know how to enable intel pstate . Nothing works . – lostsoul6 Feb 19 '24 at 18:08
  • @lostsoul6 You can set performance without installing cpufreq See the answers (including the one I just posted) on the duplicate. – WinEunuuchs2Unix Feb 19 '24 at 18:27
  • Please [edit] with cat /proc/cpuinfo ; find /sys/devices/system/cpu – Daniel T Feb 19 '24 at 18:27
  • @DanielT the output of that command was long and askubuntu didn't allow me to post it . here is the pastebin : pastebin.com/0giiKfm2 – lostsoul6 Feb 19 '24 at 19:08
  • @WinEunuuchs2Unix , I saw your post on that link . the commands don't return anything : sudo systemctl disable ondemand.service Failed to disable unit: Unit file ondemand.service does not exist . cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: No such file or directory – lostsoul6 Feb 19 '24 at 19:13
  • @lostsoul6 Thanks for trying. I retracted my close vote on the duplicate question. – WinEunuuchs2Unix Feb 19 '24 at 19:36
  • Seems like the cpufreq scaling_driver isn't loading. What is dmesg | grep intel_pstate ? https://www.suse.com/support/kb/doc/?id=000020273 – Daniel T Feb 19 '24 at 19:54
  • @DanielT it returns : [ 1.037543] intel_pstate: CPU model not supported . My server's CPU is : Intel(R) Xeon(R) CPU E5-2667 v4 @ 3.20GHz – lostsoul6 Feb 19 '24 at 20:11
  • Either it's really not supported or you need to update your kernel to the 6.5 version using HWE: https://askubuntu.com/q/248914/1004020 – Daniel T Feb 19 '24 at 21:10
