#2 Does Cpufreqd actually work?

Hi there,

I have a Notebook with Athlon Mobile Processor, running
at maximum speed @ 900 MHz, but also allowing stages at
600 and 700 MHz with lower core voltage.

I am using Gentoo Linux with the latest 2.6 kernel and
cpufreq-support built in. I also downloaded and
installed cpufreq daemon.

After having set up my own cpufreqd.conf file,
everything seems to run just fine - after raising the
verbosity-level there are the different events printed
on the system console, such as on high load the switch
to another profile etc.

My only concern is: when doing "cat /proc/cpuinfo",
always "CPU Speed = 600 MHz" is returned.

Does it only reflect the bootup status (which actually
should be 900 MHz), or does cpufreqd not work correctly?

I've been trying this while being in different cpufreq
profiles, and the value never changed ....

Thanks in advance

Michael

    you should try measuring the processor speed with some
    utility like bogomips. Sometimes the cpufreq kernel module
    does not update the cpu_mhz in-kernel variable thus not
    showing up in /proc/cpuinfo. Also take a look a cpufreq
    sysfs interface values:

    # ls -1 /sys/devices/system/cpu/cpu0/cpufreq/*
    /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
    /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq
    /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
    /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
    /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
    /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
    /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
    /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

    bye
