# 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 ..."
