perf evlist: Be more specific on -F/--freq (2015-08-10 17:20:26 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Introduce 'srcfile' sort key: (Andi Kleen)
# perf record -F 10000 usleep 1
# perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile
<SNIP>
# Overhead Source File
26.49% copy_page_64.S
5.49% signal.c
0.51% msr.h
#
It can be combined with other fields, for instance, experiment with
'-s srcfile,symbol'.
There are some oddities in some distros and with some specific DSOs, being
investigated, so your mileage may vary.
- Update the column width for the "srcline" sort key (Arnaldo Carvalho de Melo)
- Support per-event 'freq' term: (Namhyung Kim)
$ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1
$ perf evlist -F
cpu/instructions,freq=1234/: sample_freq=1234
cycles: sample_period=1000
$
Infrastructure:
- Move perf_counts struct and functions into separate object (Jiri Olsa)
- Unset perf_event_attr::freq when period term is set (Jiri Olsa)
- Move callchain option parsing code to util.c (Kan Liang)
