• UI base on Bitbar app
• This script will control your cpu values such as:
  • Long term power
  • Short term power
  • Turbo enabled
  • Undervolt values
• Included 5 Profiles for config file
  • 2 Profile on battery mode
  • 3 Profile on plug-in mode
• Base on VoltageShift kext by @sicreative
• Notification when profiles changed

Installation

• Pull source code
• Changing your cpu's value at config.sh file
• Testing it by using command bash try.sh
• Hard work for about 30min for checking stable state
• When it stable run bash install.sh to make it run at boot

• To remove, use bash uninstall.sh.

Example config.sh for my 9300H Dell Ins 7591
