perf hists browser: Consolidate callchain print functions in TUI (2014-08-22 13:12:15 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
o Don't try to find DSOs in SYSV maps (Don Zickus)
o Fallback to MAP__FUNCTION if daddr maps are NULL,
i.e. addresses get looked upon more maps (Don Zickus)
o Kernel fix to properly handle exited tasks, by returning POLLHUP values
on perf event file descriptors. Tooling changes will come next, but were
tested with this kernel fix. (Jiri Olsa)
o Add +field argument support for --field option, so that one can add
fields to the default list of fields to show, i.e. now one can just do:
perf report --fields +pid
And the pid will appear in addition to the default fields. (Jiri Olsa)
Developer stuff:
o More Intel PT prep stuff, including:
- Add a 'perf test' for tracking with sched_switch
- Add 'flush' callback to scripting API
o hists browser (used in top and report) refactorings, getting rid of unused
variables and reducing source code size by handling similar cases in a
fewer functions (Namhyung Kim).
o Explicitly include util/debug.h for powerpc, was being indirectly included,
broke the build when some change made it stop being included. (Sukadev
Bhattiprolu)
