Nice, that's exactly what I want on ppc to allow the laptops to have the CPU "nap" longer when idle ! I'll look into adding ppc support to your patch soon. BTW. Is it possible, when entering the "idle" loop, to quickly know an estimate of when the next tick shoud actually kick in ? Also, looking at the patch, I think it mixes a bit too much of x86 things with generic stuffs... like pm_idle an x86 thing. Other implementation details comments: Do you need all those globals to be exported ? And give them better names than "ltt", that makes using of system.map quite annoying ;) I don't understand your comment about "we must have all processors idle" as well... So while the whole thing is interesting, I dislike the actual kernel/dyn-tick-timer.c implementation, which should be moved to arch stuff at this point imho.
