I am currently on Pop!_OS with Gnome. My preferred DE is Pantheon/Elementary OS. I need to toggle back and forth between CPU performance states based on my workload. Basically, whether I am doing audio work (recording or mixing) or writing/data entry.

Currently, I use https://github.com/martin31821/cpupower + indicator-cpufreq to gain access to most parameters I need to control

Does a tool exist for Elementary OS that can do any of

  1. Save/recall profiles that contain different values for
  2. Min/max target frequency
  3. Enable/disable turbo boost
  4. Change pstate governor between powersave and performance
  5. enable/disable symmetric multithreading (many people ask why; each physical core only has one FPU, and thus disabling multithreading optimizes performance and more accurately reports CPU utilization in operations that rely heavily on FPU utilization)

  • Thank you! I am checking it out. In particular I wonder whether it exposes the ability to set up situation-specific configurations, as there are scenarios where I do not want optimized for battery life, but I need reliable low latency, low throughout/quiet performance during multi-track recording, or low latency, high throughput (low battery life) performance during audio mixing with lots of DSP. I appreciate this tip, thank you!

  • ethan then you can install lowlatency kernel and choose it in GRUB after the installation and reboot.
