We have demonstrated that non-idle frequencies below $\fenergy$ are generally less energy-efficient.
|
|
Based on this observation, we proposed a truncated \schedutil governor that ignores speeds below $\fenergy$.
|
|
We further demonstrate that historical CPU usage is not necessarily a reliable estimator of the active computation needs of a phone.
|
|
Based on this observation, we proposed a new governor, \systemname, that relies exclusively on hints from user-space to manage speed selections.
|
|
We identify an API that is already in use by Android to request performance boosts, and leverage it in \systemname to decide when the governor should exceed $\fenergy$.
|
|
Our proposed governors simultaneously improve performance and reduce energy consumption.
