This directory contains code to report and reset per-task CPU usage.
If the BSP supports nanosecond timestamp granularity, this this information
is very accurate. Otherwise, it is dependendent on the tick granularity.
It provides two primary features:
+ Generate a CPU Usage Report
+ Reset CPU Usage Information
NOTES:
1. If configured for tick granularity, CPU usage is "docked" by a
clock tick at each context switch.
2. If configured for nanosecond granularity, no work is done at each
clock tick. All bookkeeping is done as part of a context switch.
