发明名称 Preventing general purpose event interrupt storms in a computer system
摘要 A method and system for selectively enabling wake events in software of a computer system to overcome problems arising when hardware devices fail to clear a wake signal. The operating system manages wake events, and also distinguishes between events that are exclusively wake events, exclusively run-time events, and shared wake and run-time events. At boot time, the ACPI driver examines system tables provided by firmware to determine which GPEs are associated with wake-up events, either exclusively or shared with run-time events. These wake event associations are tracked and managed differently from events received on other hardware register pins. When the operating system receives events in a GPE Status hardware register that is enabled in a counterpart Enable register, the operating system runs an associated GPE method. When the GPE method has completed, the operating system selectively determines whether the event needs to be re-enabled.
