Cover letter [PATCH V3 0/2] rtla: Add hwnoise tool
This series present a new tool inside rtla. It is named hwnoise.
hwnoise dispatches the osnoise tracer and displays a summary of the noise. The difference is that it runs the tracer with the OSNOISE_IRQ_DISABLE option set, thus only allowing only hardware-related noise, resulting in a simplified output. hwnoise has the same features of osnoise.
An example of the tool's output:
# rtla hwnoise -c 1-5 -T 1 -d 10m -q
Hardware-related Noise
