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

 * This header declares IOCTL codes necessary to control memprof.
