class KUserBindableInterruptEvent extends KSchedulableInterruptEvent
Size : 0xC bytes
Abstract class which is a base class for KEvent and KSemaphore, 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 object (as synchronization object). In the case of KSemaphore this also increments the semaphore's count.
