摘要：
A method and system for allowing a processor to enter low power states in an information handling system (IHS) include detecting an access request for a bus mastering device. The method and system also include in response to failing to detect an access request for the bus mastering device within a period of time, suspending a bus mastering device controller associated with the bus mastering device, wherein the now suspended bus mastering controller no longer prevents the processor from entering low power states.
