Olof Johansson 5b43d20a4d [POWERPC] powerpc: Enable DEEPNAP power savings mode on 970MP ... Without this patch, on an idle system I get: cpu-power-0:21.638 cpu-power-1:27.102 cpu-power-2:29.343 cpu-power-3:25.784 Total: 103.8W With this patch: cpu-power-0:11.730 cpu-power-1:17.185 cpu-power-2:18.547 cpu-power-3:17.528 Total: 65.0W If I lower HZ to 100, I can get it as low as: cpu-power-0:10.938 cpu-power-1:16.021 cpu-power-2:17.245 cpu-power-3:16.145 Total: 60.2W Another (older) Quad G5 went from 54W to 39W at HZ=250. Coming back out of Deep Nap takes 40-70 cycles longer than coming back from just Nap (which already takes quite a while). I don't think it'll be a performance issue (interrupt latency on an idle system), but in case someone does measurements feel free to report them.
