PM Wake Up Events

The following is a list of IRQ’s (Interrupt ReQuests) and list of the events. When an I/O device wants to gain the attention of the operating system, it causes an IRQ or event to occur. When the operating system is ready to respond to the request, it interrupts itself and performs the service.
