146 | Enable kernel-style events (tracepoint) for Litmus. Litmus events | ||
147 | trace the same functions as the above sched_trace_XXX(), but can | ||
148 | be enabled independently. | ||
149 | Litmus tracepoints can be recorded and analyzed together (single | ||
150 | time reference) with all other kernel tracing events (e.g., | ||
151 | sched:sched_switch, etc.). | ||
152 | |||
153 | This also enables a quick way to visualize schedule traces using | ||
154 | trace-cmd utility and kernelshark visualizer. | ||
