tuukka.tikkanen@linaro.org 96e95182e9 cpuidle: Move perf multiplier calculation out of the selection loop ... The menu governor performance multiplier defines a minimum predicted idle duration to latency ratio. Instead of checking this separately in every iteration of the state selection loop, adjust the overall latency restriction for the whole loop if this restriction is tighter than what is set by the QoS subsystem. The original test s->exit_latency * multiplier > data->predicted_us becomes s->exit_latency > data->predicted_us / multiplier by dividing both sides of the comparison by "multiplier". While division is likely to be several times slower than multiplication, the minor performance hit allows making a generic sleep state selection function based on (sleep duration, maximum latency) tuple.
