I recently installed Fedora 42 on my HP laptop. However, whenever I resume from sleep, the frequencies of my CPU are not automatically set to the maximum when plugged in. For example:
pstate-frequency <3.15.2>
CPU_DRIVER -> intel_pstate
CPU_GOVERNOR -> performance
TURBO -> 0 [ON]
EPP -> performance
CPU_MIN -> 23% [1081MHz]
CPU_MAX -> 36% [1700MHz]
This output shows that the frequency is being limited to 1700MHz instead of running at 4700MHz.
I’m using this tool to check and set the frequencies: https://github.com/pyamsoft/pstate-frequency
I also ran cpupower frequency-set -u 4700MHz
, but nothing changes.
I tried running echo "99" | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct
, but I get the same result.
For reference, I’m also providing my CPU info in case it helps:
