Base class for interrupt events. | |||
The kernel uses the [[KInterruptEvent|KInterruptEvent]] field of a [[KEvent|KEvent]] when binding public interrupts per svcBindInterrupt request, whereas it internally uses a static object of another subclass to bind interrupt 0x0F (FIQ abstraction). | |||
| | The first first word in the object is a pointer to the object's vtable and the first function in the vtable is the interrupt handler for that interrupt number. When an interrupt runs, the function is passed its object in r0 and the interrupt number in r1. | ||
