[RFC 0/7] perf report/gtk: Add support for hierarchy view

[Namhyung Kim]

Hi guys,

This patchset implements a new feature that collects hist entries in a
hierachical manner.  That means lower-level entries are belonged to an
upper-level entry.  The entry hierachy is built on the sort keys
given, so users can set it whatever they want.  It only shows
top-level entries first, and user can expand/collapse it dynamically.

This is only implemented in --gtk currently, since it's well-matched
to the GTK tree view widget and I didn't want to be bothered with the
TUI browser code at this stage. :)

I don't attach a screenshot now, but this is an hypothetical example
on stdio.  An usual output of perf report look like:

  Overhead  Command      Shared Object                                    Symbol
  ........  .......  .................  ........................................
    22.70%  swapper  [kernel.kallsyms]  [k] intel_idle
     8.36%  swapper  [kernel.kallsyms]  [k] irqtime_acouunt_process_tick.isra.74
     1.33%  swapper  [kernel.kallsyms]  [k] __schedule


If --hierarchy (-H) option is given, it'll look like (after expanding
all children):

  Overhead  Command / Shared Object / Symbol
  ........  ..............................................
    32.39%  - swapper
    32.39%    - [kernel.kallsyms]
    22.70%        [k] intel_idle
     8.36%        [k] irqtime_acouunt_process_tick.isra.74
     1.33%        [k] __schedule

(The overhead of an upper-level entry is the sum of lower-level
entries' overhead).

You can get it from 'perf/hierarchy-v1' branch on my tree at:

Any comments are welcome, thanks!
