[PLUG] Question about cpufreqd |
I built a new low-power AMD server recently. I loaded Debian stable and then installed the cpufreq utils. They seem to be working, but I'm getting some error messages in syslog that I think I understand, but don't know how to prevent. Here's the output of 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: powernow-k8 CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 8.0 us. hardware limits: 800 MHz - 2.05 GHz available frequency steps: 2.05 GHz, 1.85 GHz, 1.65 GHz, 1.40 GHz, 1.20 GHz, 1000 MHz, 800 MHz available cpufreq governors: conservative, powersave, userspace, ondemand, performance current policy: frequency should be within 800 MHz and 2.05 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 800 MHz (asserted by call to hardware). cpufreq stats: 2.05 GHz:10.08%, 1.85 GHz:0.08%, 1.65 GHz:0.22%, 1.40 GHz:0.18%, 1.20 GHz:0.21%, 1000 MHz:0.26%, 800 MHz:88.98% (11134526) analyzing CPU 1: driver: powernow-k8 CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: 8.0 us. hardware limits: 800 MHz - 2.05 GHz available frequency steps: 2.05 GHz, 1.85 GHz, 1.65 GHz, 1.40 GHz, 1.20 GHz, 1000 MHz, 800 MHz available cpufreq governors: conservative, powersave, userspace, ondemand, performance current policy: frequency should be within 800 MHz and 2.05 GHz.

However, I'm getting this message every few seconds in syslog: Oct 24 20:14:48 VNetServer cpufreqd: cpufreqd_loop : No Rule matches current system status.
