| 17 | * The gpu_memory_total event indicates that there's an update to either the
|
| 18 | * global or process total gpu memory counters.
|
| 19 | *
|
| 20 | * This event should be emitted whenever the kernel device driver allocates,
|
| 21 | * frees, imports, unimports memory in the GPU addressable space.
|
| 22 | *
|
| 23 | * @gpu_id: This is the gpu id.
|
| 24 | *
|
| 25 | * @pid: Put 0 for global total, while positive pid for process total.
|
| 26 | *
|
| 27 | * @size: Size of the allocation in bytes.
