126 2) Open up a terminal window and execute the mode list command:
128 %> sudo ./sleepgraph.py -modes
131 Execute a test using one of the available power modes, e.g. mem (S3):
133 %> sudo ./sleepgraph.py -m mem -rtcwake 15
137 %> sudo ./sleepgraph.py -config config/suspend.cfg
139 When the system comes back you'll see the script finishing up and
141 files in subdirectory: suspend-mmddyy-HHMMSS. The ftrace file can
155 The tool sets kprobes on all delay and mutex calls to see which devices
159 The tool will also expose kernel threads that don't normally show up in the
166 to set the -mindev option to clip out any device blocks that are too small
169 %> sudo ./sleepgraph.py -m mem -rtcwake 15 -mindev 1 -dev
173 %> sudo ./sleepgraph.py -config config/suspend-dev.cfg
184 In order to see any process info, there needs to be some delay before or
187 can also be useful to run in x2 mode with an x2 delay, this way you can
193 %> sudo ./sleepgraph.py -m mem -rtcwake 15 -x2 -x2delay 1000 -predelay 1000 -postdelay 1000 -proc
197 %> sudo ./sleepgraph.py -config config/suspend-proc.cfg

205 accomplished with sleepgraph's -multi argument. You specify two numbers: the
207 delay in seconds between them. For instance, -multi 20 5: execute 20 tests with
208 a 5 second delay between each, or -multi 24h 0: execute tests over a 24 hour
209 period with no delay between tests. You can include any other options you like
216 summary-issue.html and summary-devices.html files include data taken from
219 suspend-xN-{date}-{time}:
221 summary-issues.html
222 summary-devices.html
223 suspend-{date}-{time} (1)
224 suspend-{date}-{time} (2)

242 -multi n d
244 created in a new subdirectory: suspend-xN-{date}-{time}. When the multitest
245 run is done, the -summary command is called automatically to create summary
246 html files for all the data (unless you use -skiphtml). -skiphtml will
247 speed up the testing by not creating timelines or summary html files. You
248 can then run the tool again at a later time with -summary and -genhtml to
251 -skiphtml (optional)
253 html generation. This can greatly speed up overall testing. You can then
254 copy the data to a faster host machine and run -summary -genhtml to
259 -summary indir
260 Generate or regenerate the summary for a -multi test run. Creates three
261 files: summary.html, summary-issues.html, and summary-devices.html in the
263 by kernel/host/mode, and links to the test html files. summary-issues.html
265 summary-devices.html is a list of devices and times from all the tests.
267 -genhtml
268 Used with -summary to regenerate any missing html timelines from their
277 %> sudo ./sleepgraph.py -m mem -rtcwake 10 -dev -gzip -multi 2000 0
279 or you can skip timeline generation in order to speed things up
281 %> sudo ./sleepgraph.py -m mem -rtcwake 10 -dev -gzip -multi 2000 0 -skiphtml
285 depending on whether you used the -skiphtml option. The root folder contains
290 %> cd suspend-x2000-{date}-{time}
291 %> sleepgraph.py -summary .
293 or if you need to generate the html timelines you can use -genhtml
295 %> cd suspend-xN-{date}-{time}
296 %> sleepgraph.py -summary . -genhtml
