Not necessarely. I suspect policy (generally speaking) is something you want in userspace. But I suspect this specific case might fit neatly in, or close to the skeduller. Ernest.

The driver loaded, looked, found nothing it knew about, printed the message, then bailed out. This does not necessarily mean that your hardware is not frequency scalable. It just means that the driver you tried to load did not think so. It does mean that your hardware and device driver are not compatible. Bob signature.asc Description: Digital signature

Re: Re: Cool N' Quiet
I don't think it is possible. I have AMD64 3000 and my stepping are: 2000, 1800 and 800. I think it's fixed. -- Slava Risenberg
Re: Re: Cool N' Quiet
I'm using 2.6.9-9-amd64-k8 kernel, the latest one. But probably you will need to load cpufreq-userspace module as well. And check if you have /sys mounted -- Slava Risenberg

But how can i configure the frequency-stepps? My machine have only 3. 2200, 1800 and 800 MHz. I would add a 400 or lower MHz step.

Another thing to note is that some BIOS's (like the one on my COMPAQ R3000 laptop) are broken and don't have the correct frequency table. In order to get it working you have to set the ACPI cpufreq option (CONFIG_X86_ACPI_CPUFREQ). This way the kernel will get the frequency info through ACPI, which is how windoze does it... -Ted

IMHO having ondemand in-kernel, there's no need for userspace daemons anymore... I used to have cpudyn running but now i've purged it...

Re: Cool N' Quiet
Try the 2.6.9 kernel. Compile the ondemand governor (under CPU Frequency Scaling) as a module. Put the stupid script i've attached into your initscripts directory, and configure it to run... works for me!
