Powerd error when configuring new setting



  • php-fpm 82404 /system_advanced_misc.php: The command '/usr/sbin/powerd -b hadp -a hadp -n hadp' returned exit code '69', the output was 'powerd: no cpufreq(4) support – aborting: No such file or directory'

    It gives this error when selecting either the None/ACPI or the Intel Core*.

    On bootup it gives this.

    php-cgi rc.bootup: The command '/usr/sbin/powerd -b hadp -a hadp -n hadp' returned exit code '69', the output was 'powerd: no cpufreq(4) support -- aborting: No such file or directory'

    2.4.0-BETA (amd64)
    built on Wed Feb 08 17:43:06 CST 2017
    FreeBSD 11.0-RELEASE-p7

    Intel(R) Atom(TM) CPU D2550 @ 1.86GHz
    4 CPUs: 1 package(s) x 2 core(s) x 2 hardware threads

    I don't see any negative affects from this. I assume I can ignore this?



  • You have an Intel ATOM CPU that very likely does not support EIST and FreeBSD 11 by default disables the p4tcc and apci_throttle drivers leaving no method for cpufreq driver to control the frequencies.

    https://wiki.freebsd.org/TuningPowerConsumption

    You can enable the two drivers with these lines in /boot/loader.conf.local but I don't think you'll get any benefits from it, ATOMs are broken when it comes to power and thermal tuning because they don't support EIST:

    
    hint.p4tcc.0.disabled=0
    hint.acpi_throttle.0.disabled=0
    
    


  • Thanks.

    I followed the instructions in that section, to unload the selected module I selected Non/ACPI and then rebooted.
    Same errors. But as long as there aren't issues with this error, all is good.
