perf report: Check error during report__collapse_hists() (2016-02-19 19:17:50
-0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Add 'perf record' --all-user/--all-kernel options, so that one can tell
that all the events in the command line should be restricted to the user
or kernel levels (Jiri Olsa), i.e.:
perf record -e cycles:u,instructions:u
is equivalent to:
perf record --all-user -e cycles,instructions
- Fix percentage update on key press, due to the buffering code
(that creates hist_entries that will later be consumed) touching
per hists state that is used by the display thread (Namhyung Kim)
- Bail out when event modifiers not supported by 'perf stat' are
specified, i.e.: (Wang Nan)
# perf stat -e cycles/no-inherit/ usleep 1
event syntax error: 'cycles/no-inherit/'
\___ 'no-inherit' is not usable in 'perf stat'
# perf stat -e cycles/foo/ usleep 1
event syntax error: 'cycles/foo/'
\___ unknown term
valid terms: config,config1,config2,name
#
- Enable setting names for legacy cache, raw and numeric events, e.g: (Wang Nan)
# perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.659 MB perf.data (844 samples) ]
# perf evlist
cycles
evtx
#
Miscelaneous/Infrastructure:
- Handled scaled == -1 case for counters in 'perf stat', fixing
recent, only in perf/core, regression (Andi Kleen)
- Reference count the cpu and thread maps at set_maps(), fixing the
'object code reading' 'perf test' entry when it was requesting a
perf_event_attr.sample_freq > /proc/sys/kernel/perf_event_max_sample_rate
(Arnaldo Carvalho de Melo)
- Improve perf_evlist__strerror_open() to provide hints for -EINVAL due
to perf_event_attr.sample_freq > /proc/sys/kernel/perf_event_max_sample_rate
(Arnaldo Carvalho de Melo)
- Add checks to various callchain and histogram routines (Namhyung Kim)
- Fix checking asprintf return value when parsing additional event config terms
(Wang Nan)
