KTimerAndWDTManager
class KTimerAndWDTManager extends KSchedulableInterruptEvent
Size : 0x28 bytes
This is the interrupt event object associated with SGIs #29 and #30 (timer and watchdog timer interrupts). It is also what allows GetSystemTick, SleepThread, KTimers, etc. to work.
The interrupt handler of this object updates its counter attributes and returns 0 if it was called with interuptID = 29 or 30, otherwise it does nothing and returns the object itself (does the latter ever happen?).
There is only one instance of this class (everything uses the timer and watchdog timer of core1).
