Modprobing acpi-cpufreq fails

I'm trying to load the module acpi-cpufreq, but it keeps failing:
$ sudo modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.24-ARCH/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device
however:
$ ls /lib/modules/2.6.24-ARCH/kernel/arch/x86/kernel/cpu/cpufreq/ | grep acpi
acpi-cpufreq.ko
Am I missing something?
Thanks for your time

Ok, since I'm here, I might as well ask. I don't really understand what I'm supposed to do. I have now an applet on my gnome-panel that allows me to switch between modes: conservative, ondemand, performance, and powesave. I'm not so expert about hardware. Can anyone give me some hints or point me to an easy tutorial (i.e. not too much technical jargon)?
Thanks
Do you just mean what the modes are? This article has a short description of each one. I assume that if the gnome-panel applet can select a mode, the module is already loaded. So all that you've got to do now is select the mode you want. Powersave is best for a very hot summer, ondemand is best for general use (you won't notice any slowdown).

    Hi.

    The wiki says [1] for older CPUs, I have to expect this error, but my CPU isn't really old:
    model name : Intel(R) Core(TM)2 Duo CPU T9400
    What's wrong?
    Thank you.

    I have partly solved this issue. While cool'n quiet feature is enabled in my BIOS settings; i have overclocked my cpu from BIOS. That's why cpufreq didn't work. Somehow, my BIOS disables cool'n quiet (altough it shows enabled in settings) when cpu is overclocked. Now i set my cpu to standart clocking and cpu frequency scaling begin to work. However, it runs in performance mode but i have configured it as ondemand in /etc/conf.d/cpufreq settings. Any ideas?
    [SOLVED] :
    Somehow, min and max freq were uncommented in /etc/conf.d/cpufreq. I comment them and now it works!

  • [SOLVED] acpi-cpufreq fail to load

    I had been using cpufreq to use the ondemand governor for a long time and it worked al right. Last update changed cpufreq to cpupower and I can no longer use cpu freq. scaling. And insmod won't load the acpi-cpufreq mod. I remeber well I used this module to get scaling to work. I have an amd athlon X2. And acpi support is enabled from BIOS.

    Please clean up this post. There's lot of duplicates and irrelevant stuff.
    If acpi-cpufreq suddenly stopped working after update it must be a kernel bug (unless you updated BIOS at the same time).
    Start with pacman -Syu since 3.7 branch is dead.
    Okay, but where do you see duplicates?

  • Acpi-cpufreq won't load at boot [solved]

    Hi,
    I wanted to use cpu scaling for my new laptop, eventually it works if i modprobe acpi-cpufreq so i added acpi-cpufreq to /etc/rc.conf to let it start automatic on boot but i won't. when i modprobe the module everything just works but it isn't that user friendly;) Does anyone now a solution for this problem?
    Here is my rc.conf:

    Did you actually read the wiki properly??
    http://wiki.archlinux.org/index.php/Cpufrequtils
    acpi-cpufreq is a module not a daemon, put it in the modules list, it should work then.

  • Acpi-cpufreq, pm-suspend, CPU1 set to high performance mode

    Basically, the background of the problem is that ACPI is unable to set my second core, CPU1, to the proper frequency. it gets some sort of AE_NOT_FOUND error or something in a psyloop. subsequently, the cpu0 is set by cpufreq while the second CPU, since it is not controlled by kernel at all, ends up overriding the CPU0 settings and setting the entire thing to High Performance mode. the acpi-cpufreq module then crashes and is unable to set any rules, so it defaults to 2.2 ghz and performance mode.
    I found that the only way to undo this after a resume from pm-suspend without restarting altogether is to first unload the acpi-cpufreq module (force option must be used otehrwise a "currently in use" error occurs), then reload it, then restart cpufreq daemon to make it restore the settings i have.
    $> sudo rmmod -f acpi-cpufreq
    $> sudo modprobe acpi-cpufreq
    $> sudo /etc/rc.d/cpufreq restart
    my question is, is there any way to REload the module and restart the daemon after resuming? i know that you can set acpi-cpufreq to unload on suspend, but that doesnt work because of the acpi-cpufreq module being used by another program, and i do not know how to make it forcibly unload. nor am i sure if unloading it would require me to restart the daemon still or not.
    your help/suggestions are appreciated
    -shrimants

    take a look at the wiki arch wiki pm-utils
    and create your own hook like this one:
    #!/bin/bash
    case $1 in
    hibernate)
    echo "Hey guy, we are going to suspend to disk!"
    suspend)
    /etc/rc.d/cpufreq stop
    rmmod -f acpi-cpufreq
    thaw)
    echo "oh, suspend to disk is over, we are resuming..."
    resume)
    modprobe acpi-cpufreq
    /etc/rc.d/cpufreq start
    *) echo "somebody is calling me totally wrong."
    esac

  • Cpufrequtils: Why should I care, and acpi-cpufreq vs. p4_clockmod

    I'm a cpufrequtils newbie. In the years I've been running Arch on my laptop, I've never set it up.
    I wonder, why should I care about cpufrequtils? What should I know about the technology as a laptop user? Does the fact that I rarely unplug make a difference?
    I also wonder what module I should be using for frequency scaling. The cpufrequtils article recommends acpi-cpufreq, but the article for my specific laptop recommends p4_clockmod (for some unspecified reason).
    Any insight would be greatly appreciated. Thanks in advance!

    Just modprobe both acpi-cpufreq and p4-clockmod, only one of them should be able to load.
    the article wrote:
    For older Intel CPUs, the command above may return with:
    FATAL: Error inserting acpi_cpufreq ([...]/acpi-cpufreq.ko): No such device
    In this case, replace the kernel module acpi-cpufreq with speedstep-centrino, p4-clockmod or speedstep-ich.
    CPU frequency scaling saves power and keeps your processor cooler. It's worth using on a desktop or a server, not just a laptop.
    If you use the ondemand governor, and add:
    (sleep 5 && echo 11 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold)
    to /etc/rc.local, you'll have basically zero performance loss. Usually it scales up the CPU at 95%, with this it will do it at 11% (you can't go lower atm).
    You can load the  "cpufreq_stats" module and see what it's doing with cpufreq-info. You should notice your laptop fan spin down quite a bit once you set it up.
    If you have a watt meter, you can take out the battery and see the power use drop from something like 17w to 12w.

  • Cannot modprobe acpi

    [root@localhost proteus]# modprobe acpi
    FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.12-mm2-ARCH/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device
    Uhhh... WTF? I wasn't aware that ACPI *required* CPU frequency adjust... My BIOS should support ACPI...

    Also trying to controle CPU step on a Dell Latitude L400 with a P3 (697,071MHz with speedstep), kernel-2.6.15-ARCH. No luck yet
    I first had a look at /sys/devices/system/cpu/cpu0/ where there are no 'cpufreq/' (only 'online') source
    Then '# modprobe cpufreq_userspace', '# /etc/rc.d/acpid start'  & wanted to start powernowd, but it won't start
    modprobe 'p3_clockmod' --> "not found" (BTW 'p4_clockmod' --> "Error inserting p4... (/lib/modules/.../arch/i336/kernel/..." ?)
    '# /etc/rc/d/cpudyn start' and the CPU frequence stays @ 697,071MHz.
    Then I went to the BIOS where I set (forgive the approximations in some terms) CPU-blabla to "Battery Optimized" "Authorize external applications to control blabla". Now the CPU stays glued to 497,923MHz even if I'm currently running on AC Power :?:
    Note than /proc/acpi/processor/CPU0/throttling says :
    state count :   8
    active state: T0
    states:
      *T0:  00%
       T1:  012%
       T2:  025%
       T7:  087%
    I'm just a bit lost in this location

  • Installation of the Proof of Purchase from the ACPI table failed. Error code:0xC004F059

    I just updated Window 8.0 to 8.1 for the second time as the first Time there was an UEFI issue...  the 8.1 installs and update seemed smooth... I shut down, and I leave for work. I come home fire up my PC it seems slow!! it boots...
    I notice some live tiles are active I prefer mine off so I  shut off a couple Live tiles. so then I decide to open the Mail tile and it locks up... and then one of my browsers freezes up!!! I could not open task manager at all to end the
    proses, so I decided to restart and then an app was not allowing windows to restart!!! so windows ended the task on its own could not make out what program or app it was!!! and the machine booted up slower again. I went into the event viewer
    and what do I find in there is this stuff and now looking at it this all started after the windows 8.1 update... I get it we all want the latest and greatest OS but as my mom said good things come to those whom wait don't rush into anything!!!
    and I think Microsoft you are rushing to push stuff out onto the Market... so now I have to sit here and wonder why my PC now takes 2 + minutes to load!!! (BS) and on win 8.0 it took 60 seconds... fix this please I will watch and see if
    this happens again if it keeps up I will have to once again revert back to 8.0 and at that point I will want some $$$ compensation for my loss... why should I have to go through hoops for something with the word Mircrosoft attached to it...
    I wonder how many others have had this same issue and don't even know its happening....

  • [solved] ACPI Info failed

    Hi I'm having issues with my Arch installation on my laptop
    I'm using i3wm with i3bar & i3status and have everything working fine except for one thing:
    The i3status "gets stuck" meaning it doesn't update battery/clock stats. When I reset i3status it doesn't appear anymore either. When i run ACPI in the terminal, nothing shows up (just a blank screen). Same thing with htop. Top seems to work fine but viewing the date and time through the terminal command works fine.. It's just the battery stats screwing up. Htop reads battery life also so I figure that's why it hangs..
    Here's a portion (most recent portion) of the dmesg output if it helps (there's some ACPI Error message I don't understand). This problem occurs randomly and is always fixed with a reboot.. but I'd rather not have to reboot.

    Can anyone help me figure this out? This kind of problem happened on Ubuntu 13.10 also. Thanks in advance guys.
    Edit:
    I also have my kernel parameters set as this if it helps
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2012'"
    Edit: Fixed
    So this error seems independent of i3status or anything else. It's dependent on ACPI info stuff and only fails while running on battery mode. I'm not too sure exactly what goes wrong except for that it goes in an Infinite Loop (from looking at dmesg)
    The fix that seemed to work for me is adding
    acpi_osi=Linux
    to my kernel boot paramters.
    My boot parameters in grub now looks like this
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi=Linux acpi_osi='!Windows 2012'"
    Ran on battery mode for at least 5-6 hours total, suspending and resuming, etc and so far there has been no problems. Seems like this fixed it.

    Please edit your post.
    When posting configs, code or command output, please use [ code ] tags, not [ quote ] tags https://bbs.archlinux.org/help.php#bbcode
    like this
    It makes the code more readable and - in case of longer listings - more convenient to scroll through.

  • Acpi-cpufreq supplies wrong scaling frequencies

    I have a problem with speedstepping on my Acer Extensa 3000.
    CPU is a Pentium M 1.50GHz
    the kernel modul 'acpi_cpufreq' supplies wrong available stepping frequencies.
    # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
    1600000 1400000 1200000 800000 600000
    I use a fixed DSDT table and the newst availabe BIOS Version.
    Also I tried it with the original DSDT and the other (only 2 versions are available) BIOS.
    Same results.
    If I unload the acpi_cpufreq module, the frequency jumps to the CPUs "normal" freq. 1499MHz
    (I also noticed a strange behavior: sometimes the freq jumps to values about 1700MHz or 673MHz if I unload the modul)
    `dmesg | grep -i acpi` shows no errors.

    I use the Arch stock kernel, but I don't think it's ArchLinux specific.
    I had the same problems under Gentoo and also with Vanilla kernels.
    Should I file a bugreport  to the kernel.org bugtracker or is it related to a maybe buggy BIOS?
    BTW:
    I think the Acer Extensa series was only sold in Germany.
    The Hardware of my Extensa 3000 seems to be similar to the Travlemate 4000. They use the same BIOS.

    My problem is that acpi_cpufreq reports the wrong freqs for my CPU.
    # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
    1600000 1400000 1200000 800000 600000
    As you can see the max. available freq. acpi_cpufreq reports is 1.6GHz but my CPU is only a 1.50GHz Pentium M.
    So I have to set the max.scaling freq to 1.4GHz on boot. If I don't the CPU runs at 1.6GHz and gets to hot.
    It's not related to the AC-Adapter.
    So,
    if I want to use Speedstepping I have to run the 1.5GHz at 1.4GHz.
    edit:
    @Ashren
    Sounds to me like your PC switches to some "powersave mode" if you unplug the AC-Adapter and don't switch back if it is pluged in again. Maybe there is a BIOS option that do that? In my BIOS e.g. there is an option that dims the display if I unplug the AC-Adapter.

  • Satellite A505-S6025: Win 7 64bit - driver ACPI\TOS1901 fails

    I have that problem and my laptop freeze.
    If anyone knows what it is and how i can fix it.
    thanks!!!
    the driver\driver\fwlnk failed to load for the device ACPI\TOS1901\2&daba3ff&2

    Hi
    Install the Toshiba Value Added Package for Win 7 64bit and check if it will solve your problem.
    The driver for ACPI\TOS1901 seems to belongs to Value Added Package
    As Im not mistaken the Satellite A505-S6025 was released in USA. Therefore you should use the Toshiba US driver page to get the package.

  • Cpufreq drivers error on a pentium-m 1.73GHz (dothan)

    Hi there.
    Actually I am using the arch's default kernel (2.6.31) from the core repo and I am using a pentium-m processor.
    I cannot load the speedstep-centrino module or even acpi-cpufreq module.
    ~ $ sudo modprobe speedstep-centrino
    FATAL: Module speedstep_centrino not found.
    ~ $ sudo modprobe acpi-cpufreq

    So what I am using in the pentium-m is the driver (module) p4-clockmod, but I cannot get more processor speed than 600MHz (its a 1.73GHz) - I did the configs and even forced cpufreq to a given clock frequency but it does not work for more than 600MHz.

    there is a bug report about this topic here: http://bugs.archlinux.org/task/17107
    I'm trying to recompile the kernel with some options related to the cpu scaling capability.
    also I have patched the file '/linux-2.6.31/arch/x86/kernel/cpu/cpufreq/speedstep-centrino.c' (from the kernel package)
    with a more recent speedstep-centrino.c which can be found as an attachment in one of the latest replies in the bugtracker

    No I have not hardcoded the patch.
    The patch itself has been posted by an arch member.
    You should check the bug tracker here: http://bugs.archlinux.org/task/17107
    When I was looking about the error (the speedstep-centrino module was not being loaded correctly) i found some topics about this issue in bugtrackers of gentoo and the ubuntu's launchpad.
    I had access to various kernel archives about it and the user "toorlv" told about the patch.
    You probably are confusing the model of the processor (the 715) with the number of frequencies.

    for example, I am using a Pentium M 740 1.73 GHz
    the "cpufreq-info" tells me that actually the supported frequencies are "798 MHz, 1.06 GHz, 1.33 GHz, 1.73 GHz" (notice the max is of 1.73GHz)
    and
    $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
    798000 1064000 1330000 1729000
    and I am not using the default arch kernel (in the repos)
    as you can see my kernel is the one i built.
    $ uname -a
    Linux supernova 2.6.32-pentium-m #1 ZEN SMP PREEMPT Sat Jan 23 18:08:45 WET 2010 i686 Intel(R) Pentium(R) M processor 1.73GHz GenuineIntel GNU/Linux
    notice that the kernel26-pentium-m "includes the module" into the kernel so its not loadable with modprobe. it just works without modprobe.

  • [SOLVED] Cpufreq not loading after reboot

    I followed wiki on this ,but after reboot cpufreq is not loading from /etc/rc.conf as module
    This is message on boot
    :: Setting cpufreq governing rules , cpu 0 1wrong, unknown or unhandled CPU?
    Error setting new values. Common errors:eq/scaling_available_governors: No such - Do you have proper administration rights? (super-user?)
    - Is the governor you requested available and modprobed?
    - Trying to set an invalid policy?
    - Trying to set a specific frequency, but userspace governor is not available,
    for example because of hardware which cannot be set to a specific frequency
    or because the userspace governor isn't loaded?
    But if I do a modprobe acpi-cpufreq got this
    [root@laptop ~]# modprobe acpi-cpufreq
    [root@laptop ~]# /etc/rc.d/cpufreq start
    :: Setting cpufreq governing rules , cpu 0 1 [DONE]
    This is a /etc/rc.conf/cpufreq
    #configuration for cpufreq control
    # valid governors:
    # ondemand, performance, powersave,
    # conservative, userspace
    governor="ondemand"
    # limit frequency range (optional)
    # valid suffixes: Hz, kHz (default), MHz, GHz, THz
    min_freq="800MHz"
    max_freq="2.01GHz"
    # use freq to set up the exact cpu frequency using it with userspace governor
    #freq=
    Similar happens when I want to load governors as modules.
    Laptop is acer with C2D T5800 and min and max values are  from cpufreq-info.
    Can this be solved?
    Thanks in advance!

  • [SOLVED]cpufreq misconfiguration

    After setting up and configuring cpufreq with the powernow-k8 driver here is the output of cpufreq-info:
    analyzing CPU 0:
      driver: powernow-k8
      CPUs which need to switch frequency at the same time: 0
      hardware limits: 800 MHz - 2.00 GHz
      available frequency steps: 2.00 GHz, 1.60 GHz, 800 MHz
      available cpufreq governors: ondemand, powersave, performance
      current policy: frequency should be within 800 MHz and 800 MHz.
                      The governor "powersave" may decide which speed to use
                      within this range.
      current CPU frequency is 800 MHz (asserted by call to hardware).
    My problem is with the current policy section which doesn't allow the cpu to scale up.  Anyone know what could be causing this?
    EDIT:  Disregard.  My laptop was unplugged and I didn't know it.
