Because I have a recent pentium4 and read about the new cpufreq interface in -5.4-STABLE I decided to try it. It was not a problem to fetch and compile the driver with information from the mailing list, my thanks goes to Bruno Ducrot. Unfortunately I did not found any information or software to control the cpu frequency depending from current load. So I wrote "quick and dirty" my own daemon running in user space. IMHO it works well, most of the time the frequency is set to the lowest possible value. If the cpu idle time goes under a fixed treshold the frequency is raised automatically, so there is enough power for heavy tasks. So whats the reason for this email? 1. Thanks to the people providing cpufreq interface and driver. 2. Confirmation that it seems to work well on -STABLE. 3. I want to ask the question: Are there are other, more sophisticated programs to control the current cpu frequency? 4. If desired I could release the sources for my control daemon, may be for inclusion in the base system? That requires that I beautify the sources a little bit, but that should not be a problem.
