I have an hp compaq 6710s.
Following the instructions on
http://wiki.debian.org/HowTo/CpuFrequencyScaling, i have managed to set "performance" my default(boot) governor.
Still, cpufreq-info shows me strange results:
Code:
cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0 1
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 800 MHz - 1.80 GHz
available frequency steps: 1.80 GHz, 1.80 GHz, 1.20 GHz, 800 MHz
available cpufreq governors: powersave, conservative, userspace, ondemand, performance
current policy: frequency should be within 800 MHz and 800 MHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 800 MHz (asserted by call to hardware).
cpufreq stats: 1.80 GHz:0,00%, 1.80 GHz:0,02%, 1.20 GHz:0,01%, 800 MHz:99,97% (16)

The main lines are:
Code:
hardware limits: 800 MHz - 1.80 GHz
frequency should be within 800 MHz and 800 MHz.
The governor "performance"
These two lines seem mutually exclusive, still, both are present.
How can I manage to set teh correct single speed of 1.80 Ghz instead of 800 Mhz?
