    Default 11.4/32b : no ondemand governor on pentium4

    On an asus p4C800, i have a, very old, pentium 4 3.2 GHz (HT, prescott). On which i installed an opensuse 11.4 (after some network quirks and some grub tricks)...

    First i saw that the p4_clockmod module was not compiled for the kernel.
    It took me one night to compile the modules, and it borked my whole installation, which i spent my day to remake, but that's another story.

    After loading all the appropriate modules (speedstep-lib, cpufreq-something, etc...), i run this command :
    Code:
    cpufreq-set -g ondemand
    _But_ , the governor remains viciously performance according to cpufreq-info .

    Strangely, runing this command :
    Code:
    cpufreq-set -g powersave
    changes the governor to powersave. Same for userspace and performance.
    Only conservative governor also refuses to load.

    How can i solve this ?

    CPU Speed control exists now in YaST. Why not do the following, open:

    YaST / Software / Software Management, search on Power and install yast2-power-management. Once done, restart YaST.

    Next:

    YaST / System / System Services (Runlevel), select Expert Mode Bullet at the top left:

    Now:

    Find and highlight pm-profiler and then select the button on the bottom right and Enable the pm-profile Service and answer yes to the added services requested.

    Next:

    Select the button on the bottom left and Start the pm-profiler Servrce. You should get a good start with a 0 error return code.

    Now select the finish button on the bottom right and allow your selections to be saved.

    Now:

    YaST / System / Power Management. You can select from three choices with Power Saving doing what I think you are looking for.

    jdmcdaniel3 > that doesn't work . I mean, cpu frequency does not dynamically adapt to workload, with the install and click Yast power management.
    Anyway, thanks.

    Anyone knows how to make the ondemand governor work on such a machine ?

    Hi
    If you look in the throttling file so you can check the cpu capabilities?
    Code:
    cat /proc/acpi/processor/CPU0/throttling

    malcolmlewis > it says it is not supported . That's really strange ! I have this machine since almost eight years and cpu throttling has always been supported as far as i can remember.
    How can i solve this ?

    whats the output of

    lsmod | grep acpi

    --

    Further file a bug -> bugzilla.novell.com

    There has been a lot of changes in both kernel and opensuse regarding
    cpuscaling (among them, depreacating of hal that used to load the right
    modules on boot before )

    Does

    Code:
    cpufreq-info
    show an "ondemand"-profile being available?

    gropiuskalle > cpufreq-info mentions that the ondemand governor is available. Strange !


    BTW i have to force the modprobe of P4-clockmod. And i have to manually load other cpufreq-something and speedstep-lib modules .

    Does anyone have a clue for that ?

    Maybe is there a userland script to adapt cpu frequency to workload with the userspace governor ?

    Or do people have a better idea ?
