cpu frequency concerns
Toshiba Satellite M70 -DL4
cat /proc/cpuinfo: Code:
processor : 0 Code:
driver: p4-clockmod What do I need to do in order to have the kernel recognize and operate with the correct cpu frequency? thank you, |
Hello,
It's a bug with cat /proc/cpuinfo It even does it with lots of different distros/ kernel versions My fedora does it. Code:
bogomips : 1598.06 If you search for it lots of other people have had similar findings. |
thank you kindly

Mine shows up properly...
Code:
processor : 0 Code:
cpufrequtils 003: cpufreq-info (C) Dominik Brodowski 2004-2006 Code:
/sbin/modprobe acpi_cpufreq |
Thanks all for your input. As usual, your contributions have pointed me in the right direction.
I was getting a fatal error when attempting to load the acpi_cpufreq module, because the p4-clockmod was being loaded. After blacklisting that module, I was able to load acpi_cpufreq. Secondly, my bios was incorrectly set to allow frequency scaling, so I changed that. Hence: cat /proc/cpuinfo: Code:
processor : 0 Code:
driver: acpi-cpufreq |
One thing I can highly recommend doing is building cpufreq-daemon. This has been extremely beneficial in saving my battery life. You basically set the config on how you want it to scale your processor at various power stages. ie on mine, on AC min and max are set to 1.6GHz, from 100%-50% on the battery it will sit at 600MHz unless something needs the proc, then it will bump it up the various levels up to 1.6GHz, from 25%-50% it will only go up to 1GHz, and anything below that will stay at the 600MHz range.
You have even more options than I covered here, as you can also specify the userspace governor (ie. performance, ondemand, etc). But I am glad you got it squared away. It took me forever to get this working in 10.2 and it has been getting ever easier with each slack release. Pretty soon, I will just have to carry over my conf file and not have to build anything. |
