hi,
sending out tracepoint (mostly) events display enahncements.
* adding the '--tp' option for report command to show
tracepoint related info. Use can specify following switches:
fields: shows separated tracepoint fields
format: shows tracepoints 'print fmt' in single column
(This is default if no switch is given.)
$ perf report --tp --no-children
