[PATCH v4 0/9] perf annotate: Fix --show-total-period and support --show-nr-samples

[Taeung Song]

Hello,

Currently the --show-total-period option of perf-annotate
is different from perf-report's.

It has two problem like below:
(Reported by Namhyung Kim and Milian Wolff)

  1) Wrong column i.e. 'Percent' (even though using --show-total-period)
  2) Show number of samples, not period

So fix this option on both the annotate stdio and TUI browser.
And support --show-nr-samples into perf-anntate
so that it correpond with perf-report's.

The code is available on 'perf/ann-fix-period-v4' branch at

  git://github.com/taeung/linux-perf.git

Thanks,
Taeung

v4:
- Split big patches (Arnaldo)
- Initialize width for first column on the annotate browser (Arnaldo)

v3:
- Circulate the three view (Percent, Event count, Samples) (Namhyung)
- Calculate the percent with period or number of samples (Namhyung)

v2:
- Separate the first patch into respective paches for easy review (Arnaldo)
- Add a patch to introduce 'struct sym_hist_entry' (Arnaldo)
- disasm__calc_percent() could receive a pointer to a struct sym_hist_entry
  instead of two pointer (Arnaldo)
- Add a sym_hist_entry into struct disasm_line_samples (Arnaldo) 
- Fix a case that can't switch 'the total period view' to
  'the number of samples view' on the annotate TUI browser (Arnaldo)
- Calculate the percentage with 'period', not number of samples
