The PowerTOP power consumption monitor has released
"Version 2.0 has several new key features and updates. The first big change is the use of a hardened library called libparseevents, for accessing the kernel "perf" infrastructure. With this enhancement, we are able to provide much more accurate data, and be more flexible with any future kernel development. There has been a great deal of work done in the area of CPU data measurement and diagnostics. Full accurate support was added for CPU idle, frequency, and power traces, along with expanded frequency state reporting for CPUs with more than 10 states. With these additions, PowerTOP v2.0 now gives a clearer picture of how programs affect CPU utilization, and the impact on important power-saving sleep states.
" In addition, version 2.0 adds the ability to export HTML and CSV reports, has a re-designed, tab-oriented UI, and more.
