The **rtla osnoise** tool is an interface for the *osnoise* tracer. The
|
||
|
|
*osnoise* tracer dispatches a kernel thread per-cpu. These threads read the
|
||
|
|
time in a loop while with preemption, softirq and IRQs enabled, thus
|
||
|
|
allowing all the sources of operating system noise during its execution.
|
||
|
|
The *osnoise*'s tracer threads take note of the delta between each time
|
||
|
|
read, along with an interference counter of all sources of interference.
|
||
|
|
At the end of each period, the *osnoise* tracer displays a summary of
|
||
|
|
the results.
