# 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 |
|
# |
|
# 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 ..." |
