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 Signed-off-by: Todd Brandt Signed-off-by: Rafael J.

pm-graph v5.5

2019-08-20T22:29:56+00:00

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 Signed-off-by: Todd Brandt Signed-off-by: Rafael J.
