Todd E Brandtee8b09c2014-01-16 16:18:22 -080033# Description:
34# This tool is designed to assist kernel and OS developers in optimizing
35# their linux stack's suspend/resume time. Using a kernel image built
36# with a few extra options enabled, the tool will execute a suspend and
37# will capture dmesg and ftrace data until resume is complete. This data
38# is transformed into a device timeline and a callgraph to give a quick
39# and detailed view of which devices and callbacks are taking the most
40# time in suspend/resume. The output is a single html file which can be
41# viewed in firefox or chrome.
42#
43# The following kernel build options are required:
44# CONFIG_PM_DEBUG=y
45# CONFIG_PM_SLEEP_DEBUG=y
46# CONFIG_FTRACE=y
47# CONFIG_FUNCTION_TRACER=y
48# CONFIG_FUNCTION_GRAPH_TRACER=y
Todd Brandtaf1e45e2016-07-15 23:34:14 +020049# CONFIG_KPROBES=y
50# CONFIG_KPROBES_ON_FTRACE=y
Todd E Brandtee8b09c2014-01-16 16:18:22 -080051#
Todd E Brandtb8432c62014-08-08 09:11:59 -070052# For kernel versions older than 3.15:
Todd E Brandtee8b09c2014-01-16 16:18:22 -080053# The following additional kernel parameters are required:
54# (e.g. in file /etc/default/grub)
55# GRUB_CMDLINE_LINUX_DEFAULT="... initcall_debug log_buf_len=16M ..."
