It generates output + files in subdirectory: suspend-mmddyy-HHMMSS. The ftrace file can + be used to regenerate the html timeline with different options + + HTML output: <hostname>_<mode>.html + raw dmesg output: <hostname>_<mode>_dmesg.txt + raw ftrace output: <hostname>_<mode>_ftrace.txt + + View the html in firefox or chrome. + + +Dev Mode Usage +______________ + + Developer mode adds information on low level source calls to the timeline. + The tool sets kprobes on all delay and mutex calls to see which devices + are waiting for something and when. It also sets a suite of kprobes on + subsystem dependent calls to better fill out the timeline. + + The tool will also expose kernel threads that don't normally show up in the + timeline. This is useful in discovering dependent threads to get a better + idea of what each device is waiting for. For instance, the scsi_eh thread, + a.k.a. scsi resume error handler, is what each SATA disk device waits for + before it can continue resume. + + The timeline will be much larger if run with dev mode, so it can be useful + to set the -mindev option to clip out any device blocks that are too small + to see easily. The following command will give a nice dev mode run: + + %> sudo ./sleepgraph.py -m mem -rtcwake 15 -mindev 1 -dev + + or with a config file + + %> sudo ./sleepgraph.py -config config/suspend-dev.cfg + + +Proc Mode Usage +_______________ + + Proc mode adds user process info to the timeline. This is done in a manner + similar to the bootchart utility, which graphs init processes and their + execution as the system boots. This tool option does the same thing but for + the period before and after suspend/resume. + + In order to see any process info, there needs to be some delay before or + after resume since processes are frozen in suspend_prepare and thawed in + resume_complete. The predelay and postdelay args allow you to do this. It + can also be useful to run in x2 mode with an x2 delay, this way you can + see process activity before and after resume, and in between two + successive suspend/resumes. + + The command can be run like this: + + %> sudo ./sleepgraph.py -m mem -rtcwake 15 -x2 -x2delay 1000 -predelay 1000 -postdelay 1000 -proc + + or with a config file + + %> sudo ./sleepgraph.py -config config/suspend-proc.cfg + + +------------------------------------------------------------------ +| CONFIGURATION FILES | +------------------------------------------------------------------ + + Since 4.0 we've moved to using config files in lieu of command line options. + The config folder contains a collection of typical use cases. + There are corresponding configs for other power modes: + + Simple suspend/resume with basic timeline (mem/freeze/standby) + config/suspend.cfg + config/freeze.cfg + config/standby.cfg + + Dev mode suspend/resume with dev timeline (mem/freeze/standby) + config/suspend-dev.cfg + config/freeze-dev.cfg + config/standby-dev.cfg + + Simple suspend/resume with timeline and callgraph (mem/freeze/standby) + config/suspend-callgraph.cfg + config/freeze-callgraph.cfg + config/standby-callgraph.cfg + + Sample proc mode x2 run using mem suspend + config/suspend-x2-proc.cfg + + Sample for editing timeline funcs (moves internal functions into config) + config/custom-timeline-functions.cfg + + Sample debug config for serio subsystem + config/debug-serio-suspend.cfg + + +Usage Examples +______________ + + Run a simple mem suspend: + %> sudo ./sleepgraph.py -config config/suspend.cfg + + Run a mem suspend with callgraph data: + %> sudo ./sleepgraph.py -config config/suspend-callgraph.cfg + + Run a mem suspend with dev mode detail: + %> sudo ./sleepgraph.py -config config/suspend-dev.cfg + + +Config File Options +___________________ + + [Settings] + + # Verbosity: print verbose messages (def: false) + verbose: false + + # Suspend Mode: e.g. standby, mem, freeze, disk (def: mem) + mode: mem + + # Output Directory Format: {hostname}, {date}, {time} give current values + output-dir: suspend-{hostname}-{date}-{time} + + # Automatic Wakeup: use rtcwake to wakeup after X seconds (def: infinity) + rtcwake: 15 + + # Add Logs: add the dmesg and ftrace log to the html output (def: false) + addlogs: false + + # Sus/Res Gap: insert a gap between sus & res in the timeline (def: false) + srgap: false + + # Custom Command: Command to execute in lieu of suspend (def: "") + command: echo mem > /sys/power/state + + # Proc mode: graph user processes and cpu usage in the timeline (def: false) + proc: false + + # Dev mode: graph source functions in the timeline (def: false) + dev: false + + # Suspend/Resume x2: run 2 suspend/resumes back to back (def: false) + x2: false + + # x2 Suspend Delay: time delay between the two test runs in ms (def: 0 ms) + x2delay: 0 + + # Pre Suspend Delay: nclude an N ms delay before (1st) suspend (def: 0 ms) + predelay: 0 + + # Post Resume Delay: include an N ms delay after (last) resume (def: 0 ms) + postdelay: 0 + + # Min Device Length: graph only dev callbacks longer than min (def: 0.001 ms) + mindev: 0.001 + + # Callgraph: gather ftrace callgraph data on all timeline events (def: false) + callgraph: false + + # Expand Callgraph: pre-expand the callgraph treeviews in html (def: false) + expandcg: false + + # Min Callgraph Length: show callgraphs only if longer than min (def: 1 ms) + mincg: 1 + + # Timestamp Precision: number of sig digits in timestamps (0:S, [3:ms], 6:us) + timeprec: 3 + + # Device Filter: show only devs whose name/driver includes one of these strings + devicefilter: _cpu_up,_cpu_down,i915,usb + + # Override default timeline entries: + # Do not use the internal default functions for timeline entries (def: false) + # Set this to true if you intend to only use the ones defined in the config + override-timeline-functions: true + + # Override default dev timeline entries: + # Do not use the internal default functions for dev timeline entries (def: false) + # Set this to true if you intend to only use the ones defined in the config + override-dev-timeline-functions: true + + # Call Loop Max Gap (dev mode only) + # merge loops of the same call if each is less than maxgap apart (def: 100us) + callloop-maxgap: 0.0001 + + # Call Loop Max Length (dev mode only) + # merge loops of the same call if each is less than maxlen in length (def: 5ms) + callloop-maxlen: 0.005 + +------------------------------------------------------------------ +| CUSTOM TIMELINE ENTRIES | +------------------------------------------------------------------ + +Adding or Editing Timeline Functions +____________________________________ + + The tool uses an array of function names to fill out empty spaces in the + timeline where device callbacks don't appear.

However, if a function call is not within a main timeline event, + it will spawn an entirely new event named after the caller's kernel thread. + These asynchronous kernel threads will populate in a separate section + beneath the main device/call section. + + The tool has a set of hard coded calls which focus on the most common use + cases: msleep, udelay, schedule_timeout, mutex_lock_slowpath, etc. These are + the functions that add a hardcoded time delay to the suspend/resume path. + The tool also includes some common functions native to important + subsystems: ata, i915, and ACPI, etc. + + It is possible to add new function calls to the dev timeline by adding them + to the config. It's also possible to copy the internal dev timeline + functions into the config so that you can override and edit them. Place them + in the dev_timeline_functions_ARCH section with the name of your architecture + appended. i.e. for x86_64: [dev_timeline_functions_x86_64] + + Use the override-dev-timeline-functions option if you only want to use your + custom calls, or leave it false to append them to the internal ones. + + The format is the same as the timeline_functions_x86_64 section. It's a + list of functions (set using kprobes) which use both symbol data and function + arg data.

It pulls + all the internal dev timeline functions into the config and allows you to edit + them. + + Here is a full example entry.
