I was reading the documentation on performance tuning, and did not see any mention of how the processor clock speed is changed, and if there is any way aside from rebuilding the kernel to adjust the default policy.
What documentation were you reading? The files in Documentation/cpu-freq directory of Linux kernel sources provide quite extensive description of which CPU scaling governors are available and how to tune them. If you read them, it would help if you explained in more details what you want and why it cannot be achieved by tuning available governors.
I would prefer the processor to use a higher clock speed when the system gets busy.
Do you still want it to slow down when it is not busy? What do you mean "higher" - do you want to overclock it? Otherwise it is exactly what "ondemand" CPU governor does.
I tried adjusting the: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor but was not satisfied with my results.
It would help if you provided more details about what you have done, what you observe and what you expect to see, and why exactly you are not satisfied. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
