PowerTOP v2.1 Release

BY 01 Staff (not verified) ON Aug 15, 2012

We are pleased to announce the release of PowerTOP v2.1 which concludes a minor release.

About PowerTOP

PowerTOP is a Linux tool to diagnose issues with power consumption and power management. In addition to being a diagnostic tool, PowerTOP also has an interactive mode where you can experiment with various power management settings for cases where the Linux distribution has not enabled those settings.
PowerTOP reports which components in the system are most likely to blame for a higher-than-needed power consumption, ranging from software applications to active components in the system. Detailed screens are available for CPU C and P states, device activity, and software activity.
For many years, PowerTOP has been used heavily by Intel, Linux distributors, and various parts of the open source community. We're hoping that our users find the second generation even more useful for their needs.


  • Added Transifex project integration
  • Added localization of the UI with 9 languages in progress and active
  • Support for cores without P-states
  • Support for Intel GPU statistics
  • PowerTOP manual page added
  • Added an option to specify workload to run during measurement

  • Synced Traceevent library from the kernel tree for better event parsing 
  • Bug fixes and clean ups
