This reduces the CPU cycle wastage on power9, which is SMT4. Any idle thread that's spinning is simply starving working threads on the same core of valuable resources. This can be reduced further by taking more advantage of the PSSCR supported states, as well as permitting state loss, as is currently done for power8. The currently implemented stop state is the lowest latency, which may still consume resources.
