Subject: [PATCH 0/7] Some rtla features

This set introduces some tracing facilities to rtla tools.

It adds the possibility to change the tracing_thresh to osnoise,
allowing a fine tune of OS noise detection.

It also adds the auto tracing feature (-a threshold us), which aims
helping the first approach to a problem by setting common tracing
features with a single parameter.

Finally, it also allow osnoise top and timerlat top to enable additional
trace events via (possible multiple) -e sys:event options.


Daniel Bristot de Oliveira (7):
  rtla/osnoise: Add support to adjust the tracing_thresh
  rtla/osnoise: Add an option to set the threshold
  rtla/osnoise: Add the automatic trace option
  rtla/timerlat: Add the automatic trace option
  rtla/trace: Add trace events helpers
  rtla/osnoise: Add -e/--event option
  rtla/timerlat: Add -e/--event option
