+- Once tracing is disabled, disable_trace.sh script is triggered.
+
+BREAKTRACE
+----------
+- Send break trace command when latency > USEC. This is a debugging option to control the latency
+tracer in the realtime preemption patch. It is useful to track down unexpected large latencies on a
+system. This option does only work with following kernel config options.
+
+For kernel < 2.6.24:
+* CONFIG_PREEMPT_RT=y
+* CONFIG_WAKEUP_TIMING=y
+* CONFIG_LATENCY_TRACE=y
+* CONFIG_CRITICAL_PREEMPT_TIMING=y
+* CONFIG_CRITICAL_IRQSOFF_TIMING=y
+
+For kernel >= 2.6.24:
+* CONFIG_PREEMPT_RT=y
+* CONFIG_FTRACE
+* CONFIG_IRQSOFF_TRACER=y
+* CONFIG_PREEMPT_TRACER=y
+* CONFIG_SCHED_TRACER=y
+* CONFIG_WAKEUP_LATENCY_HIST
+
+- Kernel configuration options enabled. The USEC parameter to the -b option defines a maximum
+latency value, which is compared against the actual latencies of the test. Once the measured latency
+is higher than the given maximum, the kernel tracer and cyclictest is stopped. The trace can be read
+from /proc/latency_trace. Please be aware that the tracer adds significant overhead to the kernel,
+so the latencies will be much higher than on a kernel with latency tracing disabled.
+
+- Breaktrace option will enable the trace by default, suppress the tracing by using --notrace option.
+
+Post-execute scripts
+--------------------
+post-execute script to yardstick node context teardown is added to disable the ftrace soon after the
+completion of cyclictest execution throughyardstick. This option is implemented to collect only
+required ftrace logs for effective debugging if needed.
