| # 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_DEVMEM=y |
| # 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 ..." |
