Please could you share how could it be done. I have searched in the web but could not make it run correctly!! Error setting new values. Common errors: - 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? Any help would be appreciated. Regards ------------------------------------------------------------------------------------------ Split from Energy Consumption Optimization in IoT2050.

Why don't you show us specifically what you did and where you got stuck (add attachment). Btw: no one is obliged to answer here (see forum terms). If you need an official answer, start a SR.

If you have not already installed it, please do so using the following instructions. sudo apt update sudo apt install cpufrequtils Would you consider running your applications inside Docker containers? These are quite modular and have a lot of parameters to save resources and power, e.g. maximum ratings for CPU load [%], RAM usage [MB], etc. However, the Docker Engine is already an installation option for IndOS during its setup process.
