New in PowerTop 2.0 Beta (Jan 17, 2011)
- The 2.0 codebase extensively uses the kernel "perf" infrastructure to give much more accurate data for the various reports.
- Another major feature of the 2.0 code base is that the power behavior of the various devices in the system is prominently tracked and displayed, so that it's clear which devices are problematic in terms of power behavior.
- A new power estimation engine is able to give an estimate of how much power individual devices and processes in the system are consuming.
- This release requires a relatively new kernel to work properly (2.6.37, but 2.6.36 will also work).
