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.
