On this F11-XO1 it's about 50, and almost all of them are kernel internals (i.e. things that don't prevent cpuidle from suspending). So far, I've seen hardly anything from userspace, mostly olpc-switchd, NetworkManager, and the kbdshim. IIRC, the 820 series builds had basically zero userspace wakeups. That's no accident; OLPC engineers like dsd put in a lot of work to make that happen, to the point of disabling the cursor blink in gtk. It's absolutely achievable. --Ben _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
