By blocking sleep states we can address "system level latency" or "best case latency" but as far as I can see PM QoS does not address "worst case latency". So minimum CPU frequency would be somewhat analogous - a "best case" or "system level" QoS concept. --Antti _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/linux-pm
