So, I have a small command that I would like to be executed at startup of the machine. The command is the following code.
sudo cpupower frequency-set -g powersave
since I would like the cpu governor to be powersave, at all times. It seems however, that after a reboot, this goes away.
I apologize if this is too simple of a thread, but I would just like to know the best possible way to do this.
So far, I have been looking to make a .service file to make it execute, but not quite sure if that is needed, or if I could do it more simpler, with cpupower in some way.
I appreciate all feedback, thank you.
What is your processor?
What is your processor?
I should probably have included that, my bad.
I have a Macbook Pro 15-inch, mid-2015 with the upgraded i7 4980HQ.
If you want more information, this is how my system is configured so far. I followed some optimization tips specific for macbook, saying that it was clever to disable intel_pstate for battery performance.

I think you should be using the pstate governor.
I am not expert in this subject though so wait for more replies.
No problem, thanks for your reply.
Just to make stuff more clear, I was following this: http://www.newnix.space/blog/2015/7/23/ … d-machines
Still open for answers to the question in the OP.
EDIT: I've reverted the changes. I now use intel_pstate driver, with the intel_pstate powersave governer.
If anyone could tell me what they recommend, as in intel_pstate with powersave governer, or for example acpi_cpufreq with ondemand.
Any recommendations for best performance/battery?
