pm-graph v5.9
bootgraph: - fix parsing of /proc/version to be much more flexible - check kernel version to disallow ftrace on anything older than 4.10 sleepgraph: - include fix to bugzilla 212761 in case it regresses - fix for -proc bug: https://github.com/intel/pm-graph/pull/20 - add -debugtiming arg to get timestamps on prints - allow use of the netfix tool hosted in the github repo - read s0ix data from pmc_core for better debug - include more system data in the output log - Do a better job testing input files useability - flag more error data from dmesg in the timeline - pre-parse the trace log to fix any ordering issues - add new parser to process dmesg only timelines - remove superflous sleep(5) in multitest mode config/custom-timeline-functions.cfg: - change some names to keep up to date README: - new version, small wording changes Signed-off-by: Todd Brandt <todd.e.brandt@intel.com> Signed-off-by: Rafael J.
