-# 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
-# CONFIG_FUNCTION_GRAPH_TRACER=y
-# CONFIG_KPROBES=y
-# CONFIG_KPROBES_ON_FTRACE=y
-#
-# For kernel versions older than 3.15:
-# The following additional kernel parameters are required:
-# (e.g. in file /etc/default/grub)
-# GRUB_CMDLINE_LINUX_DEFAULT="... initcall_debug log_buf_len=16M ..."
