KCacheMaintenanceInterruptEvent

class KCacheMaintenanceInterruptEvent extends KBaseInterruptEvent

This object handles data cache (L2C not included) and instruction cache maintainance.

There is only one instance of this object.

Size : 0x4C bytes (N3DS) / 0x34 bytes (O3DS)

Offset	Type	Description
0x0	void **	Pointer to vtable
0x4	u8	Cache operation
0x5	u8	Indicates whether to do the operation asynchronically (this is what is used when processes are running for ranges >= 0x200 bytes)
0x6	s8	Number of cores still doing cache maintenance operations
0x7	u8	Padding
0x8	KThread *	Thread operating on the object
0xC	void *	Start address (when applicable)
0x10	void *	End address (when applicable)
0x14	KThreadLinkedListNode *	Related to KThread+0xA0
0x18	KThreadLinkedList *	KThread+0xA8 of the current thread
0x1C	KAsyncCacheMaintenanceInterruptEvent[number of cores]	Used when the field at offset 0x5 is 1, see below

Possible operations (any other value leads to a kernel panic):

Operation	Description
4	Invalidate data cache range
5	Clean data cache range
6	Clean and invalidate data cache range
7	Invalidate instruction cache range (also flush the entire branch target cache and the prefetch buffer)
8	Invalidate entire data cache
9	Clean entire data cache
10	Clean and invalidate entire data cache
11	Invalidate entire instruction cache (also flush the entire branch target cache and the prefetch buffer)

KAsyncCacheMaintenanceInterruptEvent extends KSchedulableInterruptEvent, size = 0xC bytes:

Offset	Type	Description
0x0	void **	Pointer to vtable
0x4	KSchedulableInterruptEvent *	Next interrupt event
0x8	const KThread *	Thread woken up by the first virtual function of this object, doing the actual cache maintenance operation. Same for all
