Detailed Description

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.
