+# 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 ..."
