perf session: Add perf_session__deliver_synth_event() (2014-10-29 11:36:15 -0200)
----------------------------------------------------------------
perf/core improvements:
User visible:
* Don't open the DWARF info multiple times, keeping instead a dwfl handle
in struct dso, greatly speeding up 'perf report' on powerpc. (Sukadev Bhattiprolu)
* Introduce PARSE_OPT_DISABLED option flag and use it to avoid showing
undersired options in tools that provides frontends to 'perf record', like
sched, kvm, etc (Namhyung Kim)
Infrastructure:
* More Intel PT work, including a facility to export sample data (comms,
threads, symbol names, etc) in a database friendly way, with an script to use
this to create a postgresql database. (Adrian Hunter)
* Use make sure that thread->mg->machine points to the machine where
the thread exists (it was being set only for the kmaps kernel modules
case, do it as well for the mmaps) and use it to shorten function
signatures (Arnaldo Carvalho de Melo)
