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 # 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) #
