Hi all,
It turns out that the PM domains device stop and domain power off governor functions I invented some time ago don't really make sense, because they should only decide whether or not the resulting low-power state will be too deep and that only depends on latencies. In particular, the time when devices have been suspended doesn't really matter here, so the results returned by those functions shouldn't depend on it either (as it shouldn't depend on any "break even" values that only make sense when we know how much time in advance the device is going to be used, but this information is not related to the PM QoS latency constraint).
If this functions are fixed (patches [1/3] and [2/3]), then some ugly computations can be removed from rpm_suspend() and other places and the whole framework can be simplified quite a bit (patch [3/3]).
Thanks, Rafael
