PowerTOP v2.3 release

BY Kristen Accardi ON Mar 19, 2013

We are pleased to announce the release of PowerTOP v2.3. This is a maintenance release.

About PowerTOP

PowerTOP is a Linux tool used to diagnose issues with power consumption and power management. In addition to being a diagnostic tool, PowerTOP also has an interactive mode you can use to experiment with various power management settings, for cases where the Linux distribution has not enabled those settings.

PowerTOP reports which system components are most likely to blame for higher-than-needed power consumption, ranging from software applications to active hardware components. Detailed screens are available for CPU C and P states, device activity, and software activity.

Highlights

  • Reduced duplication in CPU code
  • Improved ARM build support
  • Various bug fixes and cleanups

Thank you to everyone who contributed to this release!
