pm-graph v5.6 

sleepgraph:
 - force usage of python3 instead of using system default
 - fix bugzilla 204773 (https://bugzilla.kernel.org/show_bug.cgi?id=204773

)
 - fix issue of platform info not being reset in -multi (logs fill up)
 - change -ftop call to "pm_suspend", this is one level below state_store
 - add -wificheck command to read out the current wifi device details
 - change -wifi behavior to poll /proc/net/wireless for wifi connect
 - add wifi reconnect time to timeline, include time in summary column
 - add "fail on wifi_resume" to timeline and summary when wifi fails
 - add a set of commands to collect data before/after suspend in the log
 - add "-cmdinfo" command which prints out all the data collected
 - check for cmd info tools at start, print found/missing in green/red
 - fix kernel suspend time calculation: tool used to look for start of
    pm_suspend_console, but the order has changed. latest kernel starts
    with ksys_sync, use this instead
 - include time spent in mem/disk in the header (same as freeze/standby)
 - ignore turbostat 32-bit capability warnings
 - print to result.txt when -skiphtml is used, just say result: pass
 - don't exit on SIGTSTP, it's a ctrl-Z and the tool may come back
 - -multi argument supports duration as well as count: hours, minutes, seconds
 - update the -multi status output to be more informative
 - -maxfail sets maximum consecutive fails before a -multi run is aborted
 - in -summary, ignore dmesg/ftrace/html files that are 0 size

bootgraph:
 - force usage of python3 instead of using system default

README:
 - add endurance testing instructions

Makefile:
 - remove pycache on uninstall

------------------------------------------------------------------



 The best way to gauge the health of a system is to run a series of

 suspend/resumes over an extended period and analyze the behavior. This can be

 accomplished with sleepgraph's -multi argument. You specify two numbers: the

 number of tests to run OR the duration in days, hours, or minutes, and the

 delay in seconds between them. For instance, -multi 20 5: execute 20 tests with

 a 5 second delay between each, or -multi 24h 0: execute tests over a 24 hour

 period with no delay between tests. You can include any other options you like

 to generate the data you want. It's most useful to collect dev mode timelines

 as the kprobes don't alter the performance much and you get more insight.



 On completion, the output folder contains a series of folders for the

 individual test data and a set of summary pages in the root. The summary.html

 file is a tabular list of the tests with relevant info and links. The

 summary-issue.html and summary-devices.html files include data taken from

 all tests on kernel issues and device performance. The folder looks like this:



  suspend-xN-{date}-{time}:

	summary.html

	summary-issues.html

	summary-devices.html

	suspend-{date}-{time} (1)

	suspend-{date}-{time} (2)

	...



 These are the relevant arguments to use for testing:



  -m mode

	Mode to initiate for suspend e.g. mem, freeze, standby (default: mem).



  -rtcwake t

	Use rtcwake to autoresume after t seconds (default: 15).



  -gzip (optional)

	Gzip the trace and dmesg logs to save space. The tool can also read in

	gzipped logs for processing. This reduces the multitest folder size.



  -dev (optional)

	Add kernel source calls and threads to the timeline (default: disabled).



  -multi n d

	Execute n consecutive tests at d seconds intervals. The outputs will be

	created in a new subdirectory: suspend-xN-{date}-{time}. When the multitest

	run is done, the -summary command is called automatically to create summary

	html files for all the data (unless you use -skiphtml). -skiphtml will

	speed up the testing by not creating timelines or summary html files. You

	can then run the tool again at a later time with -summary and -genhtml to

	create the timelines.



  -skiphtml (optional)

	Run the test and capture the trace logs, but skip the timeline and summary

	html generation. This can greatly speed up overall testing. You can then

	copy the data to a faster host machine and run -summary -genhtml to

	generate the timelines and summary.



 These are the relevant commands to use after testing is complete:



  -summary indir

	Generate or regenerate the summary for a -multi test run. Creates three

	files: summary.html, summary-issues.html, and summary-devices.html in the

	current folder. summary.html is a table of tests with relevant info sorted

	by kernel/host/mode, and links to the test html files. summary-issues.html

	is a list of kernel issues found in dmesg from all the tests.

	summary-devices.html is a list of devices and times from all the tests.



  -genhtml

	Used  with -summary to regenerate any missing html timelines from their

	dmesg and ftrace logs. This will require a significant amount of time if

	there are thousands of tests.



Usage Examples

_______________



 A multitest is initiated like this:



  %> sudo ./sleepgraph.py -m mem -rtcwake 10 -dev -gzip -multi 2000 0



	or you can skip timeline generation in order to speed things up



  %> sudo ./sleepgraph.py -m mem -rtcwake 10 -dev -gzip -multi 2000 0 -skiphtml



 The tool will produce an output folder with all the test subfolders inside.

 Each test subfolder contains the dmesg/ftrace logs and/or the html timeline

 depending on whether you used the -skiphtml option. The root folder contains

 the summary.html files.



 The summary for an existing multitest is generated like this:



  %> cd suspend-x2000-{date}-{time}

  %> sleepgraph.py -summary .



	or if you need to generate the html timelines you can use -genhtml



  %> cd suspend-xN-{date}-{time}

  %> sleepgraph.py -summary . -genhtml
