This abstract base class defines <code>virtual KInterruptEvent* InterruptEvent::handleInterruptAndKInterruptEvent(u32 interruptID) = 0</code>. It's actually the function called by the IRQ handler, which returns a [[KInterruptEvent|KInterruptEvent]] to signal.
If NULL or 1 is returned, no event will be signaled. If NULL is returned, no post-interrupt rescheduling will be done.

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).
