[PATCH 0/2] powerpc powernv platform support
by Stewart Smith
Hi!
These two patches get powertop to work on current powernv machines.
These are POWER8 based systems from IBM (and others) running OPAL firmware.
The first patch correctly parses /proc/cpuinfo so information about
processors and pstates is displayed (at all).
The second uses the existing userspace interface for getting power consumption.

cpu: support powerpc /proc/cpuinfo
Add support for power consumption sensors through opal-sensors sysfs

[Announce] PowerTOP v2.8
by Alexandra Yates
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.

This appears fixed when using Linux 4.3.
