66 Enable kernel-style events (tracepoint) for Litmus. Litmus events
67 trace the same functions as the above sched_trace_XXX(), but can
68 be enabled independently.
69 Litmus tracepoints can be recorded and analyzed together (single
70 time reference) with all other kernel tracing events (e.g.,
71 sched:sched_switch, etc.).
72
73 This also enables a quick way to visualize schedule traces using
74 trace-cmd utility and kernelshark visualizer.

76 Say Yes for debugging and visualization purposes.
77 Say No for overhead tracing.
