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 | # | |
b8432c6f | 39 | # For kernel versions older than 3.15: |
ee8b09cd TB |
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 ..." | |
