Abstract: Embodiments of a method and apparatus are described for operating a mobile computing device in different modes using different operating systems. An apparatus may comprise, for example, a memory operative to store multiple operating systems, a processor operative to execute the multiple operating systems, an operating system management module operative to select a first operating system when the mobile computing device is in a first mode or a second operating system when the mobile computing device is in a second mode and the mobile computing device is coupled to one or more external devices. Other embodiments are described and claimed.

Abstract: Methods and apparatus relating to increasing energy efficiency of sensor controllers are described. In an embodiment, logic (e.g., within a sensor controller) performs one or more tasks corresponding to acquisition of data from one or more sensors. The logic performs the one or more tasks to allow a processor core of the sensor controller to enter (or stay in) a low power consumption state during performance of the one or more data acquisition tasks. Other embodiments are also disclosed and claimed.

Abstract: An embodiment integrates non-PCI compliant devices with PCI compliant operating systems. A fabric system mimics the behavior of PCI. When non-PCI compliant devices do not know how to respond to PCI enumeration, embodiments provide a PCI enumeration reply and thus emulate a reply that would typically come from a PCI compliant device during emulation. Embodiments allow system designers to incorporate non-standard fabric structures with the benefit of still using robust and mature PCI infrastructure found in modern PCI compliant operating systems. More generally, embodiments allow an operating system compliant with a first standard (but not a second standard) to discover and communicate with a device that is non-compliant with the first standard (but possibly is compliant with the second standard). Other embodiments are described herein.

Abstract: Systems and methods of managing break events may provide for detecting a first break event from a first event source and detecting a second break event from a second event source. In one example, the event sources can include devices coupled to a platform as well as active applications on the platform. Issuance of the first and second break events to the platform can be coordinated based on at least in part runtime information associated with the platform.

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: A method and system for saving and/or retrieving context information of a processor core for a power state transition. The processor core resides in a complex power domain variously transitioning between a plurality of power states. The processor core includes a local context storage area for storage and retrieval of processor core context information. A low power context storage resides in a nominal power domain external to the complex power domain. Context information of the processor core is stored to the low power context storage based on whether a power state transition of the complex power domain includes a transition to power down the processor core.
