PowerTop OpenSolaris

As my last post mentioned we're working to take power management to the next level. Working closely with Intel and AMD and of course the SPARC folks internally. Here is some of the early features.....( OK we know this is catch up ;) but you have to catch up before you overtake ) http://www.youtube.com/OpenSolarisTesla Great work by Rafeal ( superb camera work from Andrew too ) http://www.opensolaris.org/os/project/tesla/Work/Powertop/ PowerTOP is an observability tool that shows how effectively your system is taking advantage of the CPU's power management features. By running the tool on an otherwise idle system, you can see how much time the CPUs are spending running in lower power states. Ideally, an unutilized (idle) system will spend 100% of its time running at the lowest power CPU states, but because of background user and kernel activity (random software periodically waking to poll status), idle systems typically consume more power than they should. PowerTOP shows you which software (user and kernel) is waking up, and how often. By fixing, filing bugs against, (or just not running) power inefficient software you can help improve your system's power efficiency.
