- # 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 ..."
