PowerTop for OpenSolaris v1.0

Wednesday May 14, 2008

The first release of the PowerTop tool for OpenSolaris is available at the Tesla Project's page (http://opensolaris.org/os/project/tesla/).

PowerTop is an observability tool that shows how effectively the system is taking advantage of the CPU's power management features. The tool allows the user to see how long the CPU is running at different power states, and which events are causing the system to wakeup and consequently consume more energy.

In order to run PowerTop, the user must have Solaris Nevada build 82 or higher installed.
It will also be possible to run the tool on Solaris 10 systems with Update 6 - once such update is released.

x86 and SPARC packages are available. We're also working on getting it into pkg.opensolaris.org so everyone can take advantage of the new kickass IPS packaging system on OpenSolaris 2008.05 :)

PowerTop is a community project developed on opensolaris.org. Join our alias (tesla-dev@opensolaris.org) if you're interested in getting involved.

That is the sweetest thing I have ever seen.

Is there an IPS package of PowerTOP for OpenSolaris 2008.05 available yet? If not, is there an ETA on it's creation?

Looking forward to a decent suspend-to-RAM or hibernate mode and we'll be all set.

Great work though!

Just wanted to ditto what the second commenter said. Thanks a whole bunch and look forward to the STR feature (especially if it works on the EeePCs).
