PowerTOP v2.8 Release

We are pleased to announce the release of PowerTOP v2.8.


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 you can use to 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 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.
