DVFS


DVFS is concept of tuning voltage and frequency of CPU processor dynamically as per workload scenarios.
In my knowledge, cpufreq is used to tune CPU frequency dynamically depending on selected governors.
I need some guidance in this context for Ubuntu 18.04.

Why ondemand and conservative governors are not listed to /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors? Can it be avail using any configuration? How?
Why scaling_Available_Frequencies file not present to cpufreq folder?
I need set of available CPU frequency and its associated voltage
How to tune voltage for DVFS assignment?

I would think that things like this are hardware dependant.
In other words, it isn't available on all hardware.
In other words, what hardware are you using.

Also: why do you think you need to mess with this? Don't you trust that the hardware and kernel developers already try to get the most out of your CPU?

Here's guidance: You're wanting to mess with things that can have very unwanted effects on your cpu an that your cpu may not benefit from. Don't. There's no low hanging fruit left for you to pick and transform your pc.

Rule #1:"If it ain't broke, don't fix it!"
