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 returns 0 if it was called with interuptID = 29 or 30, otherwise 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).
| Offset | Type | Description |
|---|---|---|
| 0x0 | void ** | Pointer to vtable |
| 0x4 | KSynchronizationInterruptEvent * | Next interrupt event (associated with the current one) of type KSchedulableInterruptEvent. The linked list represented by this attribute can contain cycles |
| 0x8 | u32 | Watchdog timer underflow counter |
| 0xC | u32 | Previous value of the underflow counter |
| 0x10 | KTimerAndWDTManagerInterruptEvent | Instance of a dummy subclass of KTimeableInterruptEvent used to keep track of KTimerInterruptEvents and KThreadInterruptEvent of suspended threads |
| 0x20 | KRecursiveLock | Recursive lock |
