What is PowerTOP?
PowerTOP is an open-source command line utility for Linux systems that helps users diagnose issues with power consumption and power management. It provides detailed information about which software components and hardware devices are utilizing the most power so that users can optimize them.
Some key features of PowerTOP include:
- Monitors CPU C-state residency, wakeups events, and other power management metrics in real time
- Analyzes top power consuming processes, kernel routines, drivers, and services
- Provides tuning advice and recommendations for reducing power usage
- Supports both Intel and AMD processors
- Lightweight and low overhead so it can run continually in the background
PowerTOP is useful for Linux users on laptops and other battery-powered devices who want to extend their battery life. It helps pinpoint exactly what is using excess power so intelligent power optimization decisions can be made. The advice it provides can help prolong the life of portable devices.
