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.
