| 14 | * The hypervisor's memory controller profiling infrastructure allows |
| 15 | * the programmer to find out what fraction of the available memory |
| 16 | * bandwidth is being consumed at each memory controller. The |
| 17 | * profiler provides start, stop, and clear operations to allows |
| 18 | * profiling over a specific time window, as well as an interface for |
| 19 | * reading the most recent profile values. |
