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
