My computer in the lab is amd dual-core cpu and debian etch is installed.
When I added the system monitor to the Panel, I found that the cpu usage is always above 50%, that is, there is always a core running at full load.
I searched the internet for this problem and found that almost no one of me encountered the same problem.
I think the cpu has two cores. The system must have set the operating mode of the first core, but the second core is not managed. Maybe the second core has been executing empty commands, so it is full.
Finally, I found this article to adjust the cpu frequency. After reading this article, I tried it. I did this:
1. edit/etc/modules and add the kernel module mounted by modprobe.
Cpufreq-userspace
Cpufreq-ondemand
Cpufreq-powersave
Cpufreq-conservative
Powernow-k8.ko # Please change to the corresponding frequency adjustment module, which is corresponding to my amd frequency adjustment drive.
Install sysfsutils
# Apt-get install sysfsutils
Edit/etc/sysfs. conf with the superuser permission. File Content:
Devices/system/cpu/cpu0/cpufreq/scaling_governor = ondemand
Devices/system/cpu/cpu0/cpufreq/scaling_max_freq = 1600000 # change it to the maximum CPU frequency
Devices/system/cpu/cpu1/cpufreq/scaling_governor = ondemand
Devices/system/cpu/cpu1/cpufreq/scaling_max_freq = 1600000 # change it to the maximum CPU frequency
In this way, I have set the running mode of both cpu cores. In fact, I used my cpu for downgrading, And the cpu speed was 2 GB. I only used 1.6 GB.
I don't need to be so fast, and the cpu is still power-saving and environmentally friendly.
Restart, haha, solve the problem, cpu0 and cpu1 are liberated, and live a happy life.
I often peek at them through the system monitor and find that their usage rate is generally 0%. I envy their brother's leisurely life.
