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
216 summary-issue.html and summary-devices.html files include data taken from
219 suspend-xN-{date}-{time}:

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

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.

453 all the internal timeline functions into the config and allows you to edit

507 the functions that add a hardcoded time delay to the suspend/resume path.
508 The tool also includes some common functions native to important
513 functions into the config so that you can override and edit them. Place them
517 Use the override-dev-timeline-functions option if you only want to use your
521 list of functions (set using kprobes) which use both symbol data and function

528 all the internal dev timeline functions into the config and allows you to edit
539 Verifying your custom functions
542 Once you have a set of functions (kprobes) defined, it can be useful to
545 and the -status option. The tool will go through all the kprobes (both
547 to set them in ftrace. It will then print out success or fail for you.
