Title:
コンピュータシステム用の高効率電力管理技術
Document Type and Number:
Japanese Patent JP4903272
Kind Code:
B2
Abstract:
Techniques involving power management techniques in computer systems are disclosed. For instance, an apparatus may include an input output queue (IOQ), an interface coupled to a processor, and a control module. The interface communicates with the processor regarding power states of the processor. The control module may initiate draining the IOQ upon a commencement of a power state transition for the processor. The control module allows the transition of the processor to continue during the draining of the IOQ. However, at a particular point in the transition, the control module may determine whether the IOQ is empty. If so, then the control module may allow the transition of the processor to continue. Otherwise, the control module may stop the transition of the processor until the IOQ is empty.
