Version 2.1 of PowerTOP has been released with improvements for not only Intel hardware running Linux but ARM assets as well.
PowerTOP 2.1 isn't as big of a release as PowerTOP 2.0
from earlier this year, but it does bring some notable highlights.
PowerTOP 2.1 integrates Transifex project tranlsations, locationalization of the UI with nine different languages, support for CPU cores without P-states, Intel GPU statistics support, a PowerTOP man (manual) page, an option to specify a workload during run measurement, an option to suppress output to the terminal, more ARM support assets, and a synced Trace-event library from the kernel tree. PowerTOP 2.1 also has various bug-fixes and clean-ups.
The open-source PowerTOP 2.1 is available fro Intel's 01.org project page
Already being planned for Intel's PowerTOP 2.2 update is continuing to improve the user-interface and resolution scaling, support for emerging Intel Architectures (Haswell
? Valley View
? Anything for Knights Corner
?), and support for emerging Linux kernel development.
