    摘要: A method and apparatus for intelligent power management for low power link states. Some embodiments include methods, apparatuses, and systems for a device coupled to a controller via a link; a link power management engine to alter a power state of the link based on a transaction and some knowledge of future transactions between the device and the controller; and a memory or logic to store the link power management engine. In some embodiments, the memory stores information about at least one of the following: the power state of the link, the device buffering, the controller or device state or a history of transactions. In some embodiments, the device is a peripheral of a computer system. In some embodiments, the method may include transitioning the device to various link states. Other embodiments are described.

    摘要: With embodiments of the invention, a more robust solution is provided using a storage driver that may already be used for the platforms operating system. This is efficient because the storage driver typically already monitors storage drive access requests, and thus knows when traffic is outstanding (performance may be critical) or when it's not outstanding (and power may be saved).

    摘要: A next idle state for a processor in a system may be determined based on a previous idle period and a previous idle state. The next idle state for the processor may also be determined based on times when interrupts are generated by devices in the system.

    摘要: A system for measuring and managing thermal operations of a processor core on a semiconductor die using a sensor positioned in a hotspot of the processor core. A measured temperature reading is determined based upon a temperature sensed by the sensor. Interrupt signals and a software readable register indicating temperature information provide feedback about the thermal environment to the processor. Based upon the measured temperature reading, the interrupt signals direct the processor to modify operation.

    摘要: Various methods, apparatuses, and systems are described in which a chipset controller has circuitry to control communications with a peripheral device in a computing device. The chipset controller has logic configured 1) to detect a plug-in event when the peripheral device connects to the chipset controller and 2) to transition the chipset controller from a low power consumption state to a higher power consumption state based on the logic detecting the plug-in event.

    摘要: A method and apparatus for efficient memory allocation and system management interrupt (SMI) handling is herein described. Upon waking a second processor in a multiple processor system, one may use a single SMI to initialize each processor, may use the location of a single default SMI handler as a wake-up vector to the second processor, and may patch an instruction pointer to a non-aligned address during the handling of the SMI with the second processor to forgo the traditional extra aligned memory allocation. In addition, one may use unified handler code to handle software generated SMIs on both the first and second processors and may use exit SMM directly after handling a hardware SMI to save execution time.
