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 ..." # # ----------------- LIBRARIES -------------------- import sys import

Using a kernel image built\n'\ ' with a few extra options enabled, the tool will execute a suspend and\n'\ ' capture dmesg and ftrace data until resume is complete. This data is\n'\ ' transformed into a device timeline and an optional callgraph to give\n'\ ' a detailed view of which devices/subsystems are taking the most\n'\ ' time in suspend/resume.\n'\ '\n'\ ' If no specific command is given, the default behavior is to initiate\n'\ ' a suspend/resume and capture the dmesg/ftrace output as an html timeline.\n'\ '\n'\ ' Generates output files in subdirectory: suspend-yymmdd-HHMMSS\n'\ ' HTML output: _.html\n'\ ' raw dmesg output: __dmesg.txt\n'\ ' raw ftrace output: __ftrace.txt\n'\ '\n'\ 'Options:\n'\ ' -h Print this help text\n'\ ' -v Print the current tool version\n'\ ' -config fn Pull arguments and config options from file fn\n'\ ' -verbose Print extra information during execution and analysis\n'\ ' -m mode Mode to initiate for suspend (default: %s)\n'\ ' -o name Overrides the output subdirectory name when running a new test\n'\ ' default: suspend-{date}-{time}\n'\ ' -rtcwake t Wakeup t seconds after suspend, set t to "off" to disable (default: 15)\n'\ ' -addlogs Add the dmesg and ftrace logs to the html output\n'\ ' -noturbostat Dont use turbostat in freeze mode (default: disabled)\n'\ ' -srgap Add a visible gap in the timeline between sus/res (default: disabled)\n'\ ' -skiphtml Run the test and capture the trace logs, but skip the timeline (default: disabled)\n'\ ' -result fn Export a results table to a text file for parsing.\n'\ ' -wifi If a wifi connection is available, check that it reconnects after resume.\n'\ ' [testprep]\n'\ ' -sync Sync the filesystems before starting the test\n'\ ' -rs on/off Enable/disable runtime suspend for all devices, restore all after test\n'\ ' -display m Change the display mode to m for the test (on/off/standby/suspend)\n'\ ' [advanced]\n'\ ' -gzip Gzip the trace and dmesg logs to save space\n'\ ' -cmd {s} Run the timeline over a custom command, e.g. "sync -d"\n'\ ' -proc Add usermode process info into the timeline (default: disabled)\n'\ ' -dev Add kernel function calls and threads to the timeline (default: disabled)\n'\ ' -x2 Run two suspend/resumes back to back (default: disabled)\n'\ ' -x2delay t Include t ms delay between multiple test runs (default: 0 ms)\n'\ ' -predelay t Include t ms delay before 1st suspend (default: 0 ms)\n'\ ' -postdelay t Include t ms delay after last resume (default: 0 ms)\n'\ ' -mindev ms Discard all device blocks shorter than ms milliseconds (e.g. 0.001 for us)\n'\ ' -multi n d Execute consecutive tests at seconds intervals.
