pm-graph v5.5
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 <todd.e.brandt@linux.intel.com> Signed-off-by: Rafael J.

-Use turbostat to execute the command in freeze mode (default: disabled). This
-will provide turbostat output in the log which will tell you which actual

+\fB-noturbostat\fR
+By default, if turbostat is found and the requested mode is freeze, sleepgraph
