Subject: [RFC 00/22] perf tools: Display tracepoint enahncements
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
Samples: 4K of event 'sched:sched_switch', Event count (approx.): 4788
Overhead Command Shared Object Symbol Print fmt
