| 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 systme 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. |
