Set Clock Frequency on a Frequency Scaling Disabled Kernel


Is there any method to set clock frequency statically on a Frequency Scaling Disabled Kernel?

Notes:
  • Obviously I want to set clock frequency to something less than 100% because disabling CPU_FREQ sets it to 100% itself.
  • I don't mention any specific hardware.
  • I don't want to use undervolting.

Does "enabling" the CPU Frequency Scaling allow you to have functionality for the clock frequency to be set up statically?

I'm guessing here but you may need cpufrequtils.

https://wiki.debian.org/HowTo/CpuFrequencyScaling

This may help. Good Luck.

I can summarize your answer in one word: "No".
Because I said "Frequency Scaling Disabled Kernel" and it means I can't use any utilities titled "Frequency Scaling ".
And yes by these utilities it's possible to decently manipulate cpu frequency.
BTW thanks.

You're Welcome.

I found a link for working with CPU Frequency Governors.
This looks like a start but not sure if it's what you want. <trying here to help>

https://www.kernel.org/doc/Documenta.../governors.txt

Try looking on some of the Linux Kernel Developers websites for a fix?
I'm not sure but you may be able to write code or write a script to achieve what you want.

Another idea would be to find a few men in Debian Testing to chat with that might know a way around getting the clock set up statically.
Write to the men at ZDNET, Linux IRC Channels, The Linux Foundation, Linux Journal, and other various Linux Magazines. Write to the Team at Bad Voltage, they might do a podcast about it if you ask.

Go through the documentation of the distribution that you are running and see if a way to accomplish what you want is implemented.

Maybe other members will see your thread and know a fix for what you need.
Sorry, I'm out of ideas.
