I like having a separate ranking for power to sort the states. To me it seems that min residency could be ambiguous for this. We could have states with inverted min_residencies: where a lower consumption state has a lower target residency because the cost is recovered more quickly. Such a state might have higher latency for exit, so even though the lower min_residency/lower power state is clearly preferable, selection of the lower power state may be prevented by kernel latency constraints.
