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.
