Tools regarding CPU power and tuning options. More information: https://manned.org/cpupower.
- List CPUs:
sudo cpupower {{[-c|--cpu]}} {{all}} info
- Print information about all cores:
sudo cpupower {{[-c|--cpu]}} {{all}} info
- Set all CPUs to a power-saving frequency governor:
sudo cpupower {{[-c|--cpu]}} {{all}} frequency-set --governor {{powersave}}
- Print CPU 0's available frequency governors:
sudo cpupower {{[-c|--cpu]}} {{0}} frequency-info {{[-g|--governors]}} | grep "analyzing\|governors"
- Print CPU 4's frequency from the hardware, in a human-readable format:
sudo cpupower {{[-c|--cpu]}} {{4}} frequency-info {{[-w|--hwfreq]}} {{[-m|--human]}}
