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
