Hi, I'm a bit confused on how power management and cpu load (should) work together... I'm not talking about a busy cpu clocking higher and so on but about how system usage is reported when the cpu frequency changes. I run KDE and the CPU meter (systemloadviewer plasmoid) behaves very erratically. One moment I have 50% load, then the next it drops down to 26% only to go back up to 50% seconds later. When checking what is going on in the system I noticed nothing unusual. I have most services disabled for security reasons and run a pretty light desktop After a little digging I found that my system usage barely seems to change - just enough to frequently push the CPU one step up in clock frequency and then it drops back down almost immediately. As soon as I fixed the clock frequency at the highest (cat scaling_max_freq > scaling_min_freq) the cpu usage was reported as perfectly steady... So - that leads me to a few questions: Am I doing something wrong? My view is pretty simple but the few tests I did seemed to all indicate the same thing... How valuable is reporting the CPU usage if its not really shows how much of maximum CPU power is used? Wouldn't it make more sense to show CPU usage normalized to the maximum frequency rather than the current frequency? Does the load as display with uptime compensate for power management? I went through some of the kernel code the scheduler and the cpufreq kernel modules but didn't see anything.
