Cool. I've been watching some of the videos for the OLPC project where they are creating a 1 Watt computer system. The CPU goes into shutdown and recovers in hundredths of milliseconds. They've combed through the kernel code for "loop until something happens" code and replaced it with sleeping code triggered by the event submission. Best of all, all the changes are filtered back into the mainline kernel code where they not only keep power requirements down on laptops, but servers and big iron, too. The power savings are amazing. -- Ted Roche Ted Roche & Associates, LLC http://www.tedroche.com _______________________________________________ Post Messages to: ProFox@leafe.com Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[EMAIL PROTECTED] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
