Hi, Since I was not yet able to build a working cpufreq_ondemand.ko to allow automatic frequency scaling for JUN's loader 1.04b (DSM 6.2.2-24922 Update 2), i've written this script to allow dynamic CPU frequency scaling. It's hosted here : https://github.com/Trauma/cpufreq-userspace-scaler # cpufreq-userspace-scaler ##### Cpu frequency scaling script for cpufreq userspace governor ## If you're missing ondemand or conservative governors, this script is for you. This script is scaling cpu frequency according to current average load. You can set 3 frequency steps : low, mid, high. This 3 thresholds will automatically set cpu frequency accordingly : - the `lowload` threshold will set the cpu to his minimal frequency, unless you force it to `scalingminfreq` - the `midload` threshold will set the cpu to approximate mid range cpu frequency - the `highload` threshold will set the cpu to his maximal frequency, unless you force it to `scalingmaxfreq` If you set `scalingmaxfreq` and/or `scalingminfreq` the cpu will never override those values. ### Usage : ### Parameters : Variable name | Default | Type | Comments ----------------|---------|-----------------------------|----------- lowload | 050 | integer between 000 and 999 | 050 = load average : 0.50 midload | 065 | integer between 000 and 999 | 065 = load average : 0.65 highload | 085 | integer between 000 and 999 | 085 = load average : 0.85 scalingminfreq | auto | integer in hertz | 800000 = 800 Mhz scalingmaxfreq | auto | integer in hertz | 2500000 = 2,5 Ghz ### Default commande line : `./scaling.sh &` ### Custom command line example : `lowload=100 highload=200 scalingmaxfreq=2000000 scalingminfreq=1500000 ./scaling.sh &` Enjoy.

Hi, everyone, Thanks for you patience. A new ds918 loader support 6.2/6.21 is uploaded. whats new: uefi issue fixed. i915 driver updated. link https://mega.nz/#F!Fgk01YoT!7fN9Uxe4lpzZWPLXPMONMA (for DS918+) - v1.04b ---Beginning of addition by polanskiman--- link https://mega.nz/#!OV4gVKyZ!dCgfXx1bgAOyvbFwFiov3s7RSNoFuqnAcNmSllLoUiw (for DS3615xs) - v1.03b link https://mega.nz/#!zcogjaDT!qIEazI49daggE2odvSwazn3VqBc_wv0zAvab6m6kHbA (for DS3617xs) - v1.03b Please read this topic to know what loader to chose: ---End of addition by polanskiman---

thanks you, work like a charm!

Yes. you can do it.

does it work with DSM 6.2.2 Update 3?

Long answer : Your CPU don not have only 3 modes, synology kernel for DS918+ provides only three cpufreq governors : powersave > set the cpu to its minimal freq performance > set the cpu to its maximal freq userspace > allow you to specify the desired frequency. This script use this governor to modulate the frequency according to system load (that's basically whats explained in the README). Short answer : no need to "modify some text", just RTFM

Installation in rc.d will not work since this script do not provide start and stop args. As @Olegin spotted you can launch it form the task manager, that's the way i use it. Installation example (from your nas cli) : sudo curl https://raw.githubusercontent.com/Trauma/cpufreq-userspace-scaler/master/scaler.sh -o /usr/local/bin/scaler.sh && sudo chmod +x /usr/local/bin/scaler.sh Then run it through a startup triggered task, as root, in your DSM, with the following command : /usr/local/bin/scaler.sh & or with parameters : lowload=100 highload=200 scalingmaxfreq=2000000 scalingminfreq=1500000 /usr/local/bin/scaler.sh &
