 Posted: Tue Sep 20, 2005 2:15 am Post subject: CPUFreq Scaling problems [SOLVED] |
 |
|
I have tried to get cpufrequency scaling working to no avail on my IBM Thinkpad. I have a 1.7ghz Pentium-m dothan thingy in here and I believe I have compiled all relevent stuff in my kernel but when I boot up I get a message saying "CPUFreq support has not been compiled into the kernel". This pops up striaght after acpid loads up.
Heres my kernel .config

When I run cpufreq-info it tells me:

I don't seem to be getting anywhere with this at the moment...It's like smacking my head against a brick wall lol....anyone know where I'm going wrong?

Since you have an IBM machine, perhaps you should enable this. I don't know if this is the problem though, I have basically the same settings here, and cpudyn works fine, though cpufreqd also never worked for me. Perhaps just try cpudyn, it does the same...

| You have to add the dothans to the speedstep_centrino.c (part of the kernel sources). Search for the thread with a title containing "undervolting", the patch / the entries for the dothans are there. Worked for me and my desktop pentium-m-board. |

Thanks for the help guys I think I just got it sorted 
fourhead: I got the acpi_ibm package emerged because it was a newer version...that works fine.
Magic Michael: Gave that thread a read and was like  So recompiled the kernel with my centrino speedstep bit as a module with the debug info so I could see what was going on...modprobed it and it worked which is very strange but I'm not complaining. Just been messing around with the ondemand governor which seems to be working fine too.
I love Gentoo! I almost got this machine setup perfectly  |
