 <p>Print a timed per-thread callgraph, complete with function parameters and return values.  The first parameter names the function probe points to trace.  The optional second parameter names the probe points for trigger functions, which acts to enable tracing for only those functions that occur while the current thread is nested within the trigger.</p></li>

+<p>The Linux kernel function smp_call_function causes expensive inter-processor interrupts (IPIs). The scf.stp script tallies the processes and backtraces causing the interprocessor interrupts to identify the cause of the expensive IPI. On exit the script prints the tallies in descending frequency.</p></li>
