    Please change it to the version I improved again and try it.
    A few days ago, the permission problem of the sh file was fixed.

     

    https://github.com/PeterSuh-Q3/tcrp-addons/tree/main/cpufreq-scaler/src

     

    There was a bug that counted the number of cores rather than threads of the CPU, so there was a problem that only half of the threads were processed.
    Fixed a few other issues.

    Nice work, though it could have been cool to open a PR on my repo ;)

    I'm successfully intalled and running this script (with some modifications to properly scaling for all 4 threads).

    But my kill a watt does change anything even when all cpu cores running at 800MHz :D is that abnormal?

    Most of the time hard drives are way more power hungry than one CPU on this type of setup. You're PSU efficiency is also important, a 500w 80+ Power Supply can drain around 50w without any load. So in this case scaling down the CPU is more a matter of temperature management IMHO.

    Since i can not explain why your sensor id do not start @ 1 and since you seems to be the only one with this issue. I'll recommend you to mod the script before installation. Just change :

      

    currtemp=$(cat /sys/bus/platform/devices/coretemp.0/hwmon/hwmon0/temp1_input)
maxtemp=$(cat /sys/bus/platform/devices/coretemp.0/hwmon/hwmon0/temp1_max)

    to 

    currtemp=$(cat /sys/bus/platform/devices/coretemp.0/hwmon/hwmon0/temp2_input)
maxtemp=$(cat /sys/bus/platform/devices/coretemp.0/hwmon/hwmon0/temp2_max)

     

    And launch the install.sh

    please tell me why install doesn't work 

    Oct 24 20:47:11 DOM scaler.sh[24007]: cat: /sys/bus/platform/devices/coretemp.0/hwmon/hwmon0/temp1_input: No such file or directory

     


    This is your problem, to help you out i'll need to know what are your syno model, DSM version and CPU model.

    Ok, thanks.

     

    So the new cpucorecount method works for you too, since it return 7 and you can see that you have /sys/devices/system/cpu/cpu0 to /sys/devices/system/cpu/cpu7 which is fine.

     

    FYI `awk '{ print $1 - 1 }'` means `print the first field of the previous command minus 1` Since nproc return 8 for you, and since /sys/devices/system/cpu/cpu0 start at 0 we need to remove one core form the count to obtain the right value (7 for you). This to said that you first experiments were totally hazardous, and I can not explain why it worked for you.

     

    If you want me to help further, please run the latest version of the script with `bash -x ./scaler.sh` and paste the output here (no screenshots please).

     

    Cheers.

    @burtal it seems like cpucorecount is not set properly for you. can you give me the output of those commands please :

    nproc | awk '{ print $1 - 1 }'

    and

    grep cores /proc/cpuinfo | sort -u | awk '{ print $4 - 1 }'

    and

    grep cores /proc/cpuinfo | sort -u | awk '{ print $7 - 1 }'

    and
    ls -l /sys/devices/system/cpu/

    cpucorecount=$(nproc)  instead of  {print $4-1}  part ? .....

     

    to be clear ..... here , after =?

    # Get cpu cores count minus 1, to allow maping from 0
    cpucorecount=$(grep cores /proc/cpuinfo | sort -u | awk '{ print $4 - 1 }')

     

    and  here ?

     

      # Set load steps to trigger frequencies scaling, this user overidable
      lowload=$(grep cores /proc/cpuinfo | sort -u | awk '{ print $4 * 0.3 * 100 }')
      midload=$(grep cores /proc/cpuinfo | sort -u | awk '{ print $4 * 0.6 * 100 }')

     

    The complete and correct cpucorecount command should be :

    cpucorecount=$(nproc | awk '{ print $1 - 1 }')

     

    If it return the right value, the same method can be used for lowload etc..

    trying to get this working on a 3622xs  7.1.0-U2  on a microservergen8 with a xeon E3 1265v2

     

    If i modify in scaler.sh

     

    # Get cpu cores count minus 1, to allow maping from 0
    cpucorecount=$(grep cores /proc/cpuinfo | sort -u | awk '{ print $4 - 1 }')

     

    From 4-1 to 7 -1 ....nothing happens .... if i leave the default 4-1 , only 4 cores  show low freq.

     

    Am i doing something wrong here ?

    Also made a trigger task in dsm to run at boot under root with this command   :

    Try to use this please :

    cpucorecount=$(nproc)
     

    I've tested this successfully on my config, i think it should work for hyperthreaded and standard threaded CPU's

    Processor J3455, script

    currtemp=$(cut -c 1-3 </sys/bus/platform/devices/coretemp.0/hwmon/hwmon0/temp1_input)

    does not correctly display the temperature of 3 digits, so the processor is always in cooling mode.

    currtemp=$(cut -c 1-2 </sys/bus/platform/devices/coretemp.0/hwmon/hwmon0/temp1_input)

    now everything is OK))

    Thanks for you're feedback. I'll need to know what kernel / model and DSM version you are using please.

    Hi, I came across this topic searching for a way to scaling the CPU on DS3615xs DSM 7.0.1. CPU scaling has been set up through cpufrequtils for this same machine when it was on 6.2.3, now it seems ondemand mode is missing from the governor in DSM 7.0.1.

     

    I tried the script here, I got:

    root@xxx:~# /usr/local/bin/scaler.sh &
    [1] 19296
    root@xxx:~# /usr/local/bin/scaler.sh: line 48: /sys/bus/platform/devices/cor            

    etemp.0/hwmon/hwmon0/temp1_input: No such file or directory
     

    Any idea?

    This happen when the script try to get the current temperature of the CPU (overheat protection), if you can find out a way to get this information on your config I could adapt the script.

    hi! had the same problem on rptc 7.1-42661 Update 1 (no such file or directory trying to cat scaling governor) and it was fixed after loading the acpi-cpufreq module manually (modprobe acpi-cpufreq). hope it helps!

     

    Thanks @true, I've waited a while for someone to report if manually loading the driver worked on 7.1. 

     

    Could someone report the output of this command please, after loading acpi-cpufreq :

      

    lsmod| grep "cpufreq"

    Just want to make sure all dependencies are loaded before fixing the script, thks.

    unfortunately doesn't work anymore on 7.1

    cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: No such file or director

     

    It was a great script! :( 

     

     

    What syno model do you use ?

     

    What is this command output : cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver

     

    Thx.
