TECHNOLOGIES FOR COLLABORATIVE HARDWARE AND SOFTWARE SCENARIO-BASED POWER MANAGEMENT

摘要

Technologies for collaborative hardware-software power management include a computing device having a processor that supports a low-power idle state. The low-power idle state may be connected standby or a low-power audio playback state. The computing device detects a present usage scenario and determines whether the usage scenario qualifies for a power boost. Qualifying usage scenarios may include low-power audio playback, screen-on interactive use, and I/O-bound workloads. For qualifying usage scenarios, the computing device applies a boosted power management policy that increases power consumption and performance compared to a default power management policy. The default power management policy may base performance and power consumption on recent processor utilization. The computing device may generate one or more hardware hints to increase performance and power consumption, such as increasing the processor p-state or setting the value of an energy performance bias register. Other embodiments are described and claimed.
