Что я пытался сделать:
[console]
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
2401000 2400000 2300000 2200000 2000000 1900000 1700000 1600000 1500000 1400000 1300000 1200000 1100000 900000 800000 768000
$ cpufreq-set --max 2401000
$ echo 2401000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
[/console]
Но все равно в выводе cpufreq-info такие строчки
[console]
current policy: frequency should be within 768 MHz and 1.70 GHz.
[/console]
и в файле /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq значение 1700000.
Как поставить максимальную частоту?
