Forwarding causes of non-maskable interrupts to the interrupt handler
摘要:
The present invention relates to a method and apparatus for directing causes of non-maskable interrupts. The apparatus determines whether a computer system is designed to handle an alternative interrupt such as a SCI interrupt. If the system is capable of handling alternative interrupts, forwarding circuitry forwards the causes of non-maskable interrupts to an alternative interrupt handler. If the system is not capable of handling alternative interrupts, the apparatus forwards the cause of non-maskable interrupts to a NMI handler.
