pm-graph: AnalyzeBoot v2.1
- changed output from single html file to dir with html/dmesg/ftrace - add sysinfo to logs and timeline - add -sysinfo command, displays dmidecode values and cpu/mem info - set trace buffer size to lesser of memtotal/2 or 2GB when using callgraph - extended timeline to the last init call in user space separated timeline into two phases, kernel mode & user mode - add kernel version check for ftrace usage, 4.10 minimum - change -filter argument to -func - add strict protections on -func usage with full symbol checks now only works for statically linked functions cmd -flistall now ignores all loadable module functions - add -cgfilter argument for reducing timeline size by removing callgraphs - crontab usage: preserve existing @reboot lines in user crontab - fedora support added: uses grub2 loader, handles fedora crontab - stop using "which" to find binaries, search pre-defined path list - moved most output processing to analyze_suspend library Signed-off-by: Todd Brandt <todd.e.brandt@linux.intel.com> Signed-off-by: Rafael J.
