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.
