Currently using: powersave governor
Currently turbo boost is: off

I think /sys/devices/system/cpu/cpu*/cpufreq/energy_performance_preference should not contain balance_power when powersave governor is used. Let me know if I'm wrong. Have "Extreme performance" setting in BIOS, not sure if its relevant. Kernel 6.14.
