# Description:
#	 This tool is designed to assist kernel and OS developers in optimizing
#	 their linux stack's suspend/resume time. Using a kernel image built
#	 with a few extra options enabled, the tool will execute a suspend and
#	 will capture dmesg and ftrace data until resume is complete. This data
#	 is transformed into a device timeline and a callgraph to give a quick
#	 and detailed view of which devices and callbacks are taking the most
#	 time in suspend/resume. The output is a single html file which can be
#	 viewed in firefox or chrome.
#
#	 The following kernel build options are required:
#		 CONFIG_PM_DEBUG=y
#		 CONFIG_PM_SLEEP_DEBUG=y
#		 CONFIG_FTRACE=y
#		 CONFIG_FUNCTION_TRACER=y
