perf script: Add option --show-switch-events (2015-07-23 22:51:14 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
New features:
- Introduce PERF_RECORD_SWITCH(_CPU_WIDE) and use it in 'record' to
ask for context switches, allowing non priviledged tasks to know
when they are switched in and out, which wasn't possible with
the other context switch tracepoint and software events, see the
patch description for a comprehensive justification (Adrian Hunter)
- Stop collecting /proc/kallsyms in perf.data files, saving about
4.5MB on a typical x86-64 system, use the symbol resolution
routines used in all the other tools (report, top, etc) now that
we can ask libtraceevent to use perf's symbol resolution code.
(Arnaldo Carvalho de Melo)
User visible fixes:
- Expose perf's symbol resolver to libtraceecent, so that its plugins can
resolve tracepoint fields to kernel functions, like the 'function' field
in the "timer:hrtimer_start tracepoint" (Arnaldo Carvalho de Melo)
Infrastructure:
- Map propagation of thread and cpu maps improvements, prep work for
'perf stat' new features (Jiri Olsa)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Adrian Hunter (5):
perf: Add PERF_RECORD_SWITCH to indicate context switches
perf tools: Add new PERF_RECORD_SWITCH event
perf record: Add option --switch-events to select PERF_RECORD_SWITCH events
perf script: Don't assume evsel position of tracking events
perf script: Add option --show-switch-events
Arnaldo Carvalho de Melo (8):
perf symbols: Add front end cache for DSO symbol lookup
perf symbols: Introduce map__is_(kernel,kmodule)()
tools lib traceevent: Allow setting an alternative symbol resolver
perf symbols: Provide libtraceevent callback to resolve kernel symbols
perf trace: Provide libtracevent with a kernel symbol resolver
perf script: Switch from perf.data's kallsyms to perf's symbol resolver
perf tools: Stop reading the kallsyms data from perf.data
perf tools: Stop copying kallsyms into the perf.data file header
Jiri Olsa (5):

perf evlist: Force perf_evlist__set_maps to propagate maps through events
perf evlist: Use bool instead of target argument in propagate_maps()
perf evlist: Tolerate NULL maps in propagate_maps
perf header: Use argv style storage for cmdline feature data
