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.
摘要翻译：用于协作硬件 - 软件电源管理的技术包括具有支持低功率空闲状态的处理器的计算设备。低功率空闲状态可以连接待机或低功率音频播放状态。计算设备检测当前使用情景并确定使用情景是否符合功率提升。合格使用场景可能包括低功耗音频播放，屏幕交互式使用和I / O绑定工作负载。对于符合条件的使用情况，计算设备应用增强的电源管理策略，与默认电源管理策略相比，可提高功耗和性能。默认的电源管理策略可以基于最近处理器利用率的性能和功耗。计算设备可以生成一个或多个硬件提示以增加性能和功耗，例如增加处理器p状态或设置能量性能偏置寄存器的值。描述和要求保护其他实施例。
