33 | # 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 |
49 | # CONFIG_KPROBES=y |
50 | # CONFIG_KPROBES_ON_FTRACE=y |
51 | # |
52 | # For kernel versions older than 3.15: |
53 | # 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 ..." |
