KUserBindableInterruptEvent

class KUserBindableInterruptEvent extends KSchedulableInterruptEvent

Size : 0xC bytes

Abstract base class for KEventInterruptEvent and KSemaphoreInterruptEvent, to be used with svcBindInterrupt.

It appears that semaphores were originally planned to be bindable by svcBindInterrupt (except for the FIQ abstraction interrupt, SGI #15). The sole reason preventing semaphores to be used with svcBindInterrupt is a type check.

For public interrupts (i.e. anything else than SGI #15 in this case), svcBindInterrupts sets the flag that indicates that the interrupt shall be disabled after each time the interrupt is received.

The second virtual function reenables the interrupt (using the interrupt ID) and signals the parent object. In the case of KSemaphoreInterruptEvent this also increment the parent semaphore's count.

Offset	Type	Description
0x0	void **	Pointer to vtable
0x4	KSynchronizationInterruptEvent *	Next interrupt event (associated with the current one), usually a KSchedulableInterruptEvent. The linked list represented by this attribute can contain cycles
0x8	s32	Interrupt ID, -1 by default
