[BUG] setFrequency: getIntelHWP/getIntelTurbo fails

Created by: fenz

Describe the bug Changing frequency governor produce errors.

To Reproduce

  • LIKWID command and/or API usage
$ likwid-setFrequencies -p

No support for Uncore frequencies

  • LIKWID version and download source (Github, FTP, package manger, ...) $ likwid-setFrequencies --version likwid-setFrequencies -- Version 5.1.1 (commit: 233ab943543480cd46058b34616c174198ba0459) download -> configure -> make -> make install (all default config)

  • Operating system Ubuntu 20.04

To Reproduce with a LIKWID command Please supply the output of the command with -V 3 added to the command:

Additional context I saw in the documentation "intel_pstate" may be an issue: https://github.com/RRZE-HPC/likwid/wiki/likwid-setFrequencies#notice On the other hand it seems it should be supported since version 4.3: https://github.com/RRZE-HPC/likwid/issues/185 So I don't really understand how I should configure it. That's my processor (in case it is useful): https://ark.intel.com/content/www/us/en/ark/products/196603/intel-core-i5-1035g1-processor-6m-cache-up-to-3-60-ghz.html All is pretty much "default" so I didn't really change any configuration/setting in GRUB/BIOS Other setFrequency command options give similar errors:

$ likwid-setFrequencies -l
ERROR - [./src/frequency_cpu.c:getIntelHWP:861] No such file or directory.
Cannot read register 0x770
Cannot get frequencies from cpufreq module
The intel_pstate module allows free selection of frequencies in the available range
Minimal CPU frequency 0.4
Maximal CPU frequency 3.6

but it seems it is able to get the frequency. I feel that's a mis or missing configuration but I can't really get what I need to set/change.
