Does 64studio 2.0 kernel support powernow processors? "dmesg | grep powernow" returns nothing. I installed some packages from etch repos, including nvidia drivers but there wasn`t any kernel conflict/replacement, so the kernel is original. Best regards. Tobiasz.

Powernow is not that bad...

Hi i love cpu freq scaling since i do a lot of work on the go and it helps to save lots of power. Sometimes i do ardour tracking in mobile situations using the powersave governor, and you can change to performance when doing cpu hungry stuff. Anyway is no good idea to use jack with the ondemand governor since your clock will be jumping around, anyway i did it sometimes without any xruns or audible problems. Check this: http://64studio.com/node/143 and this howto (start from the "2.6 doing it with modules" section and read "Debian Notes" at the end) http://www.thinkwiki.org/wiki/How_to_make_use_of_Dynamic_Frequency_Scaling

I'm not familiar with installing these things when they aren't present, but you can see some more detected information with: cat /proc/cpuinfo

Frequency scaling has been disabled by default, as it can cause serious problems using jackd in real time. You can install it if you want, but be warned....

I am aware, but I`d like to have it working, after all I can turn it off or switch to performnce, if needed. Tell me only what am I to do/install to make it work? I tried powernowd, but nothing happens. Dmesg doesn`t even show type of powernow cpu. You know much more about it than I, help me. Please:) Tobiasz. PS.: What do You mean "audio frequency scaling disabled"?

Sorry, I haven't played with it (and nor will I now, having another project on the go) Perhaps someone else played with it?

You have to install the

You have to install the needed packages to use cpu freq scaling (your choice between cpudyn, powernowd or powersaved). And then configure governors and that kind of stuff.
