 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 ..."

1853 # Description:
1854 #        [deprecated for kernel 3.15 or newer]
1855 #        Legacy support of ftrace outputs that lack the device_pm_callback
1856 #        and/or suspend_resume trace events. The primary data should be
1857 #        taken from dmesg, and this ftrace is used only for callgraph data
1858 #        or custom actions in the timeline. The data is appended to the Data
1859 #        objects provided.
