PowerTOP v2.5 released!

PowerTOP v2.5 Release
We are pleased to announce the release of PowerTOP v2.5.

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.

* support for the Intel Baytrail-M CPU counters
* new "auto-tune" option which sets all tunable options to the GOOD setting
* support for the 3.12 libtraceevent code base
