class KTLBOperationsInterruptEvent extends KBaseInterruptEvent
There is one instance of this object per core.
Size : 0x10 bytes
| Offset | Type | Description |
|---|---|---|
| 0x0 | void ** | Pointer to vtable |
| 0x4 | KProcessHwInfo* | Context info (for operation 1) |
| 0x8 | void * | Virtual address (for operation 2) |
| 0xC | u32 | Current operation |
Possible operations (any other value leads to a kernel panic):
| Operation | Description |
|---|---|
| 0 | No operation (when an operation is completed, the interrupt handler sets this value) |
| 1 | Invalidate unified TLB entries on context ID match |
| 2 | Invalidate entire unified TLB |
| 3 | Invalidate unified TLB entries on VA match |
| 4 | Reset context: sets the context ID to 0 and TTB0 to <end of userland memory> |
