[PATCH 00/10] perf python: Add support to access tracepoint fields

[Jiri Olsa]

hi,
adding support to access tracepoint fields in python scripts.

With this patchset it's possible to access tracepoint fields
in event python object like:

  print "time %u prev_comm=%s prev_pid=%d prev_prio=%d prev_state=0x%x ==> next_comm=%s next_pid=%d next_prio=%d" % (
         event.sample_time,
         event.prev_comm,
         event.prev_pid,
         event.prev_prio,
         event.prev_state,
         event.next_comm,
         event.next_pid,
         event.next_prio)

Also available in:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/fixes

thanks,
jirka
