This set introduces some tracing facilities to rtla tools: - Add the possibility to change the tracing_thresh to osnoise, allowing a fine tune of OS noise detection. - Add 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. - Add -e/--event option, allowing osnoise and timerlat to enable additional trace events via (possible multiple) -e sys:event options. - Add the --filter option to filter the previous -e event. - Add the --trigger option to allow the usage of tracing trigger of the previously set -e event. If the trigger is hist: one, rtla automatically saves the hist file associated with the -e event.
