Adaptively disabling and enabling sleep states for power and performance

摘要

Methods and systems may provide for determining whether a runtime disablement condition is met with respect to a sleep state and disabling the sleep state if the runtime disablement condition is met. Additionally, the sleep state may be enabled if a runtime reinstatement condition is met. In one example, determining whether the runtime disablement condition is met includes determining a false entry rate for the sleep state, and comparing the false entry rate to an energy-based threshold, wherein the sleep state is disabled if the false entry rate exceeds the energy-based threshold.

1. A mobile platform comprising:
a battery to provide power to the mobile platform; and an input output (IO) module including,
comparison logic to determine whether a runtime disablement condition is met with respect to a sleep state of the mobile platform, wherein the runtime disablement condition is based on one or more of a false entry rate for the sleep state, an interrupt frequency for the sleep state, or a latency for the sleep state, and wherein the sleep state is selected from one of a plurality of sleep states having different levels that range from shallow to deep,disablement logic to adaptively disable the sleep state if the runtime disablement condition is met, wherein disabling the sleep state is to remove the sleep state from contention as a selected sleep state to reduce the likelihood that a false entry will occur, andenablement logic to adaptively enable the sleep state if a runtime reinstatement condition is met, wherein enabling the sleep state is to place the sleep state into contention as a selected sleep state to increase the likelihood that an optimal sleep state is selected.
