So far I've found temporary solution for my problem at Maximum CPU frequency stuck at low value, but the question that I have is how to make it permanent. Right after reboot, frequencies are set back to stock 1.90GHz.
CPU Model = Intel(R) Core(TM) i7-3517U CPU @ 1.90GHz
/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies = 2401000 2400000 2300000 2200000 2100000 1900000 1800000 1700000 1600000 1500000 1400000 1300000 1100000 1000000 900000 800000 [kHz]
/sys/devices/system/cpu/cpufreq/boost = 1
Some other information that might be, or not, relevant:
vitaliy:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit 1900000
and...
vitaliy:~$ cat /sys/module/processor/parameters/ignore_ppc0
From what I've noticed, ignore_ppc
and scaling_available_frequencies
are overwritten every time on boot/reboot. Not sure for bios_limit
.
