    摘要: In some embodiments, the method and apparatus to provide for the detection of processor transition states is described. Some embodiments include at least two threads which provide detection for high and low priority states, which provide for power state transitions by the operating system: The low priority thread runs just prior to entry into an idle or low power state; the high priority thread runs when the idle state is ended or the highest power state is reached. In some embodiments, the use of these threads provides for the detection of processor state transitions and idle times independently of the operating system. Other embodiments are described.

    摘要: In some embodiments, an apparatus includes processor cores, a smaller non-volatile memory, a larger non-volatile memory to hold an operating system, programs, and data for use by the processor cores. The apparatus also includes volatile memory to act as system memory for the processor cores, and power management logic to control at least some aspects of power management. In response to a power state change command, a system context is stored in the smaller non-volatile memory followed by the volatile memory losing power, and in response to a resume command, the volatile memory receives power and receives at least a portion of the system context from the smaller non-volatile memory. Other embodiments are described.

    摘要: A method for reducing BIOS resume time from a computer system sleeping state, and corresponding components and system for implementing the method. The method first identifies an operating system (OS) type running on a computer system. Based on the operating system type that is identified, a set of BIOS resume tasks specific to that operating system type are dispatched for execution in response to a sleep mode wake event. Generally, the OS-type specific BIOS resume tasks may be stored on various storage means, such as BIOS devices, operating system files, or as a carrier wave. In one embodiment, various generic BIOS resume tasks and corresponding dispatch flag data are stored in one or more tables. In another embodiment, various sets of BIOS resume tasks are stored in separate tables or lists, wherein the sets of BIOS resume tasks may be operating system type and/or computer platform type specific.

    摘要: In one embodiment of the invention, a system management interrupt (SMI) handler is invoked in response to an SMI. The SMI handler determines a thermal state of a processor. The SMI handler interacts with one of a speed step technology applet and a thermal driver in a thermal management operating system to transition the processor to one of a low power state and a high power state based on the thermal state according to a native performance control status.

    摘要: A method for entering a particular C state to save power based on bus master activities. The current method is only applied when the current C state has been promoted to C3 and bus master activity has been detected since the last time BM_STS was sampled. The C3 target state is overridden by the C2 state anytime bus master traffic has occurred since the last time BM_STS was read and cleared. The OS reads the status bit on every idle entry where the target is C3. If the BM_STS is set, the idle handler clears it and enters the C2 state. If the BM_STS bit is clear, the idle handler enters C3. The difference being that the handler will enter C2 only for one instance, but will still keep the target C state set to C3.
