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
