[PATCHv3 0/3] perf python: Add support to access tracepoint fields

From: Jiri Olsa
Date: Sat Jul 16 2016 - 12:11:29 EST


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

v3 changes:
- once again fixed is_printable_array [Steven]
- patch 3/3 already merged
- added new patch 3/3 with automated test for is_printable_array

v2 changes:
- most of the patches is already pulled in,
this is just leftover
- fixed is_printable_array [Steven]
- making is_printable_array global
- attached unrelated fix 3/3

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)

thanks,
jirka
