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 2 frequency steps : low, mid. This 2 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, if load goes higher it will scale to max scalingmaxfreq

If you set scalingmaxfreq and/or scalingminfreq the cpu will never override those values.

Usage :

Parameters :

Variable name	Default	Type	Comments
lowload	auto / 30%	integer between 000 and 999	050 = load average : 0.50
midload	auto / 60%	integer between 000 and 999	065 = load average : 0.65
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 midload=200 scalingmaxfreq=2000000 scalingminfreq=1500000 ./scaling.sh &

Systemd service installer

for DSM 7.0 and above

1. If needed, set desired lowload and midload values in cpufreq-userspace-scaler.service
2. Launch the installer ./install.sh
