Good, so this ties in with our general hunt for the last lost microwatt :-) > My plan is to use parts of what has to be done to make suspend work and > combine it with cpufreq so the CPU can be always running but in a very > low clock speed. Hmm, that seems to be an unusual scenario. In what cases do you think this would be preferable to just doing a regular suspend ? One potential scenario I was thinking of would be a low-overhead task that doesn't need a lot of peripherals, e.g., MP3 playback. There, it may be possible to get better overall power efficiency by running at a constant low speed than being in stop-and-go mode with bursts of high speed. (What would also make MP3 playback a good case is that we have almost no buffering in hardware :-( ) - Werner
