HELP PLEASE: CPU throttling not working on NAS Box
hi, i'm trying to get speedstep to work on a intel ss4200 NAS box with a core 2 duo e4600 cpu. I'm running Fedora 13; Kernel 2.6.34.7-56.SS4200.fc13.x86_64, which is custom with a couple of patches to properly enumerate the hard drive controler. see this link on gentoo forums for my patches. For some reason the cpu frequency driver it is picking is "p4-clockmod", how do i force the kernel to load the correct driver???
Code:
$ cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
driver: p4-clockmod
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.00 ms.
hardware limits: 300 MHz - 2.40 GHz
available frequency steps: 300 MHz, 600 MHz, 900 MHz, 1.20 GHz, 1.50 GHz, 1.80 GHz, 2.10 GHz, 2.40 GHz
available cpufreq governors: userspace, performance
current policy: frequency should be within 300 MHz and 2.40 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 2.40 GHz.
analyzing CPU 1:
driver: p4-clockmod
CPUs which run at the same hardware frequency: 1
CPUs which need to have their frequency coordinated by software: 1
maximum transition latency: 10.00 ms.
hardware limits: 300 MHz - 2.40 GHz
available frequency steps: 300 MHz, 600 MHz, 900 MHz, 1.20 GHz, 1.50 GHz, 1.80 GHz, 2.10 GHz, 2.40 GHz
