analyzing CPU 0:
driver: p4-clockmod
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.00 ms.
hardware limits: 233 MHz - 1.87 GHz
available frequency steps: 233 MHz, 467 MHz, 700 MHz, 933 MHz, 1.17 GHz, 1.40 GHz, 1.63 GHz, 1.87 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 233 MHz and 1.87 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 233 MHz (asserted by call to hardware).
cpufreq stats: 233 MHz:14,11%, 467 MHz:1,06%, 700 MHz:0,69%, 933 MHz:2,04%, 1.17 GHz:1,37%, 1.40 GHz:0,63%, 1.63 GHz:2,01%, 1.87 GHz:78,11% (18)
Спасибо за подсказки, cpufreq-set заработала, но задача, увы, не решена.
1. При снижении частоты таким способом потребление не снижается, а даже повышается
2. Разгон невозможен.
