install_latest_from_github.sh:
- Added a new script which allows users to install the latest pm-graph
from the upstream github repo. This is useful if the kernel source
version has issues that have already been fixed in github.
sleepgraph.py:
- Updated all the dmesg suspend/resume PM print formats to be able to
process recent timelines using dmesg only.
- Added ethtool output to the log for the system's ethernet device id the
ethtool exists. This helps in debugging network issues.
- Made the tool more robustly handle events where mangled dmesg or ftrace
outputs do not include all the requisite data. The tool fails gracefully
instead of creating a garbled timeline.

- if wakeups occur in s2idle: "freeze time: N (-x ms waking y times) ms"
- change FREEZELOOP and FREEZEWAKE to S2LOOP and S2WAKE for brevity
- returns all sysfs vals to their initial state after testing
- use the dmesg log for debugging until the test is completed,
instrument the executeSuspend process to have a full trace,
if test completes, formal dmesg log overwrites the debug log
- fix CPU_ON and CPU_OFF devices in the timeline, should include [n]

Important fixes:
- in s2idle, use timekeeping_freeze trace mark instead of
machine_suspend to denote entry into s2idle mode.
- in s2idle, use machine_suspend trace mark to create a new virtual
device called "s2idle_enter_<n>x". It denotes an s2idle_enter call
loop of <n> iterations where s2idle was never actually achieved.
It isn't counted as "freeze time" in the header.
- in s2idle, only show multiple freeze times if s2idle went in and
out of resume_noirq. Otherwise multiple freezes are shown with
"waking" time subtracted (waking time is time spent outside s2idle
dealing with wakeups).
- in s2idle summaries, include "FREEZEWAKE" as an issue when at
least 1ms is spent waking from s2idle. A clean run should only
wake for the rtc timer.
- add support for device callbacks with matching names in the same
phase. In rare cases some devices register multiple callbacks from
separate drivers using the same name. Without this fix only one is
shown.
- add kparamsfmt string back to fix bootgraph
General updates:
- when suspend_machine is missing, error says "failed in
suspend_machine"
- extract target count/time and add to summary title if -multi
used
- include any instances of "timeout" in dmesg as issues to be
logged.
- fix ftrace parse to handle any number of flags (instead of
just 4).
- remove sync/async_device string from device detail, remains in
hover.
- when using callgraph (-f) add driver name to callgraph titles.

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

Upgrade bootgraph/sleepgraph to be able to run on python2 and python3.
Both now simply require python, the system can choose which to use.
bootgraph python3 update:
- add floor function to handle integer arithmetic
- change argument loop to use next() instead of args.next()
- open dmesg log and popen in binary, use decode(ascii, ignore)
- sort all html data to allow diff between python versions
- change exception handler to use python3 as instead of comma
sleepgraph python3 update:
- import configparser not ConfigParser (p2 needs python-configparser)
- add floor function to handle integer arithmetic
- change argument loop to use next() instead of args.next()
- handle popen output in binary, use decode(ascii, ignore)
- sort all html/output data to allow diff between python versions
- force gzip open to use text mode, same for file open
- ensure no binary data is written to logs (ascii convert devprops info)
- use codecs library to handle zlib encoding for mcelog data
- remove all uses of python3.7 keyword "async" as members or vars
- assume all FPDT and DMI data is in binary string form
sleepgraph:
- turbostat will be used by default if it's found & the mode is freeze
- a new option "-noturbostat" will disable its use
- fix bug where two callgraphs with the same start time overwrite.
- fix s2idle processing where two suspend/resume_machines occur back2back
- update getexec function to use which first (assuming PATH exists)
- new platforminfo data in log with: lspci, gpe counts, /proc/interrupts
- new data is zipped, b64 encoded, and tacked on the end of ftrace
