Hi, some of you already know that I've been working on getting Linux (and Fedora) to be a lot better about power usage on laptops by avoiding spurious wakeups and context switches and such (look at the "wakeup" bug in fedora bugzilla ;). As part of my job at Intel I've now released a user friendly tool that allows everyone that uses it to see what the biggest problems on their own laptop are... The results internally to Intel have been really good; several people gained an hour of battery just by using the tool and getting rid of (or fixing) 'broken' applications. PowerTOP can be downloaded from http://www.linuxpowertop.org
Very cool. Web site and mail archives are very slow though. Is there some tracker bugs for some of the core issues. Playing with it you see things like firefox right up the top of the list, along with a number of in kernel stuff (usb, libata etc) which, at a guess, people would already be aware of so there's probably already people working on it for things like OLPC. BTW, with the in-kernel cpuspeed stuff does the cpuspeed daemon still need to be run as it seems to be right up there too? Cheers, Pete (hoping one day to get the advertised 6 hours out of his extended battery) -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
