Abstract:
Systems, apparatuses, and methods for intentionally delaying servicing of interrupts in a computing system are disclosed. A computing system includes a processor that services interrupts generated by components of the computing system. An interrupt controller detects a received interrupt and intentionally delays servicing of the interrupt depending on various conditions. If the interrupt is a first type of interrupt and the processor is in a first power state, servicing of the interrupt is delayed by a first period of time. If the interrupt corresponds to the first type of interrupt and the processor is in a second power state, servicing of the interrupt is delayed for a period of time that is longer than the first period of time. If a non-maskable interrupt is received before expiration of either the first or second period of time, then servicing of any previously delayed interrupts is allowed to proceed.
