This script parses a function trace and then produces a hierarchical view of the 
function call stack after processing it into a tree.

You can see the result on attachment. You will find the raw trace and the hierarchical view.

+
+This script parses a trace provided by the function tracer in
+kernel/trace/trace_functions.c
+The resulted trace is processed into a tree to produce a more human
+view of the call stack by drawing textual but hierarchical tree of
+calls. Only the functions's names and the the call time are provided.
+
+Usage:
+	Be sure that you have CONFIG_FUNCTION_TRACER
+	# mkdir /debugfs
+	# mount -t debug debug /debug
+	# echo function > /debug/tracing/current_tracer
+	# cat /debug/tracing/current_tracer > ~/raw_trace_func
+	Wait some times but not too much, the scripts is a bit slow.
+	Break the pipe (Ctrl + Z)
+	$ scripts/draw_functrace.py < raw_trace_func > draw_functrace
+	Then you have your drawn trace in draw_functrace
