METHOD AND APPARATUS FOR PROCESSING HOT KEY INPUT USING OPERATING SYSTEM VISIBLE INTERRUPT HANDLING

摘要

Embodiments include an interrupt handling system to generate an operating system visible interrupt such as message signaled interrupt or interprocessor interrupt by an advanced configurationand power mangement interface (ACPI) and ACPI source language infrastructure. The interrupt handling system may be used to service hot keys. This interrupt handling system allows for easy upgrading of system functionality by updating a driver.
