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 keeps tracks of the system uptime and manages KTimeableInterruptEvent instances.

The interrupt handler of this object updates its counter attributes and returns 0 if it was called with interuptID = 31 (or any invalid interruptID value) (Watchdog timer underflow), otherwise it does nothing and returns the object itself (timer interrupt).

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	KTimeableInterruptEvent	Instance of a subclass of KTimeableInterruptEvent used to keep track of all instances of KTimeableInterruptEvent. Also keeps tracks of the system uptime in CPU ticks, this is updated each time a KTimeableInterruptEvent is added to its list
0x20	KRecursiveLock	Recursive lock
