Ríad, Going slightly further than the discussion this morning, where you were trying to lock the CPU to a specific frequency for thermal reasons, you may also want to look at thermald, as it might serve you better in keeping the CPU under a specific temperature, while letting the CPU scale, as you'll save a lot of power if you can let it idle all the way down (and obviously heat as well). It would also be helpful if you can describe what you are ultimately trying to accomplish, as there may be other, better, solutions. --------------- Minnowboard: --------------- cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to [email protected], 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: 600 MHz - 1000 MHz available frequency steps: 1000 MHz, 800 MHz, 600 MHz available cpufreq governors: ondemand, performance current policy: frequency should be within 600 MHz and 1000 MHz.
