Generating system management interrupt in response to usb controller signal and processing interrupt routine in upper most level of system memory

摘要

Systems and methods for enabling computer system devices and components are disclosed. A method for use in a computer system having a processor includes receiving an input from a device coupled to the system and generating an interrupt signal in response to the input. The method further includes placing the system in a management mode in response to the interrupt and processing an interrupt routine associated with the interrupt. The method further includes processing the interrupt routine located in an upper level of the system's available memory and providing information to a driver associated with the system.
