The performance governor for cpufreq doesn't seem to behave as adverti
The kernel in use: 3.2.0-23-generic on Ubuntu 12.04LTS
For example, I issue the following command:
sudo cpufreq-set -c 0 -g performance
sudo cat cpuinfo_cur_freq
If I do:
Then, to make it even more weird, if I do:
analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 1 2 3 8 9 10 11 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 1.60 GHz - 3.60 GHz available frequency steps: 3.60 GHz, 3.60 GHz, 3.47 GHz, 3.33 GHz, 3.20 GHz, 3.07 GHz, 2.93 GHz, 2.80 GHz, 2.67 GHz, 2.53 GHz, 2.40 GHz, 2.27 GHz, 2.13 GHz, 2.00 GHz, 1.87 GHz, 1.73 GHz, 1.60 GHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 3.60 GHz and 3.60 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency is 3.60 GHz. ...
