22 # Description:
23 # This tool is designed to assist kernel and OS developers in optimizing
24 # their linux stack's suspend/resume time. Using a kernel image built
25 # with a few extra options enabled, the tool will execute a suspend and
26 # will capture dmesg and ftrace data until resume is complete. This data
27 # is transformed into a device timeline and a callgraph to give a quick
28 # and detailed view of which devices and callbacks are taking the most
29 # time in suspend/resume. The output is a single html file which can be
30 # viewed in firefox or chrome.
31 #
32 # The following kernel build options are required:
33 # CONFIG_PM_DEBUG=y
34 # CONFIG_PM_SLEEP_DEBUG=y
35 # CONFIG_FTRACE=y
36 # CONFIG_FUNCTION_TRACER=y
37 # CONFIG_FUNCTION_GRAPH_TRACER=y
38 #
39 # For kernel versions older than 3.15:
40 # The following additional kernel parameters are required:
41 # (e.g. in file /etc/default/grub)
42 # GRUB_CMDLINE_LINUX_DEFAULT="... initcall_debug log_buf_len=16M ..."
