Created page with "Category:Kernel objects class KTimerAndWDTManager extends KSchedulableInterruptEvent Size : 0x28 bytes This is the interrupt event obj..."

New page

[[Category:Kernel objects]]
class [[KTimerAndWDTManager]] extends [[KSchedulableInterruptEvent|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).
