Abstract: Techniques to provide processor state for implementing a power state transition of a processor. In an embodiment, an operating system executing on a processor detects an opportunity to transition the processor to an idle processor power state. In particular embodiments, the operating system initiates the transition by invoking a task switch, wherein information describing a state of the processor is saved to a task switch segment.

Abstract: Methods and apparatus relating to platform power consumption reduction via power state switching are described. In one embodiment, control logic causes a processor to enter a first low power consumption state (e.g., S0ix) instead of a second low power consumption state (e.g., S3) based on whether a threshold time period exists between a first wake event (e.g., corresponding to a first one of one or more awake requests) and a second wake event (e.g., corresponding to a second one of the one or more awake requests). Other embodiments are also claimed and disclosed.

Abstract translation: 描述了通过电源状态切换降低平台功耗的方法和设备。 在一个实施例中，控制逻辑使得处理器基于在第一次唤醒事件（例如，第一次唤醒）之间是否存在阈值时间周期而导致第一低功耗状态（例如，S0ix）而不是第二低功耗状态（例如，S3） ，对应于一个或多个唤醒请求中的第一个）和第二唤醒事件（例如，对应于一个或多个唤醒请求中的第二个唤醒请求）。 还要求和公开其它实施例。

Abstract: Systems and methods may provide for determining an absolute energy break-even time for a first low power state with respect to a current state of a system. A relative energy break-even time may also be determined for the first low power state with respect to a second low power state based on at least in part the absolute energy break-even time. In addition, an operating state may be selected for the system based on at least in part the relative energy break-even time.

Abstract: A system and method of managing power may include determining a power state based on a first power management request from a first operating system executing on a mobile platform and a second power management request from a second operating system executing on the mobile platform. The first operating system and one or more components of the mobile platform can define a first virtual machine, and the second operating system and one or more components of the mobile platform can define a second virtual machine. In addition, the power state may be applied to the mobile platform.
