perf stat: Move perf_counts struct and functions into separate object

2015-08-08T17:16:49+00:00

Moving 'struct perf_counts' and associated functions into separate
object, so we could remove stat.c object dependency from python build.

It makes the python code to build properly, because it fails to load due
to missing stat-shadow.c object dependency if some patches from Kan
Liang are applied.

So apply this one, then Kan's.

perf stat: Move 'interval' into struct perf_stat_config

2015-08-06T19:03:04+00:00

Moving 'interval' into struct perf_stat_config. The point is to
centralize the base stat config so it could be used localy together with
other stat routines in other parts of perf code.

perf stat: Introduce --per-thread option

2015-06-26T15:05:04+00:00

Currently all the -p option PID arguments tasks values get aggregated
and printed as single values.

Adding --per-tasks option to print values per task.

  $ perf stat  -e cycles,instructions --per-thread -p 30190,30242
  ^C
   Performance counter stats for process id '30190,30242':

               cat-30190                     0      cycles
               yes-30242         3,842,525,421      cycles
               cat-30190                     0      instructions
               yes-30242        10,370,817,010      instructions

         1.143155657 seconds time elapsed

Also works under interval mode:

  $ perf stat  -e cycles,instructions --per-thread -p 30190,30242 -I 1000
  #           time             comm-pid                  counts unit events

       1.000073435              cat-30190                14,066      instructions

       2.000204830              yes-30242         9,045,796,885      instructions
  ^C     2.771286639              cat-30190                     0      cycles

It works only with -t and -p options, otherwise following error is
printed:

  $ perf stat  -e cycles --per-thread  -I 1000 ls
  The --per-thread option is only available when monitoring via -p -t options.
      -p, --pid        stat events on existing process id
      -t, --tid        stat events on existing thread id

perf stat: Introduce perf_evsel__alloc_stats function

2015-06-26T14:46:00+00:00

Move all stat allocation logic related to stat object under single
function. This way we can use it separately for stat object out of
evlist object.
