  perf hists browser: Add 'L' hotkey to change percent limit (2016-02-03 12:24:22 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

New features:

- Add 'L' hotkey to dynamicly set the percent threshold for histogram
  entries and callchains, i.e. dynamicly do what the --percent-limit
  command line option to 'top' and 'report' does. (Namhyung Kim)

Infrastructure:

- Per hists field and sort lists, that will be used, for instance,
  in the c2c tool (Jiri Olsa)

Documentation:

- Update documentation of --sort and --perf-limit options
  for 'perf report' (Namhyung Kim)

[PATCH 01/29] perf hists: Factor output_resort from hists__output_resort

[Arnaldo Carvalho de Melo]

See http://www.infradead.org/rpr.html

From: Jiri Olsa <jolsa@kernel.org>

Currently hists__output_resort() depends on hists based on hists_evsel
struct, but we need to be able to sort common hists as well.

Cutting out the sorting base sorting code into output_resort
function, so it can be reused in following patch.

[PATCH 02/29] perf hists: Introduce perf_evsel__output_resort function

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

Adding evsel specific function to sort hists_evsel based hists. The
hists__output_resort can be now used to sort common hists object.

[PATCH 03/29] perf hists: Add _idx fields into struct perf_hpp_fmt

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

Currently there's no way of comparing hpp format entries, which is
needed in following patches.

Adding _idx fields into struct perf_hpp_fmt to recognize and be able to
compare hpp format entries.

[PATCH 04/29] perf hists: Use struct perf_hpp_fmt::idx in perf_hpp__reset_width

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

We are going to add dynamic hpp format fields, so we need to make the
'len' change for the format itself, not in the perf_hpp__format
template.

[PATCH 07/29] perf hists: Make hpp setup function generic

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

Now that we have the 'equal' method implemented for hpp format entries
we can ease up the logic in the following functions and make them
generic wrt comparing format entries:

  perf_hpp__setup_output_field
  perf_hpp__append_sort_keys

[PATCH 10/29] perf hists: Allocate output sort field

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

Currently we use static output fields, because we have single global
list of all sort/output fields.

We will add hists specific sort and output lists in following patches,
so we need all format entries to be dynamically allocated. Adding
support to allocate output sort field.

[PATCH 15/29] perf hists: Introduce struct perf_hpp_list

From: Jiri Olsa <jolsa@kernel.org>

Gather output and sort lists under struct perf_hpp_list, so we could

Replacing current perf_hpp__list and perf_hpp__sort_list lists with
single perf_hpp_list instance.

[PATCH 23/29] perf hists: Add struct perf_hpp_list argument to helper functions

[Arnaldo Carvalho de Melo]

See http://www.infradead.org/rpr.html

From: Jiri Olsa <jolsa@kernel.org>

Adding struct perf_hpp_list argument to following helper functions:

  void perf_hpp__setup_output_field(struct perf_hpp_list *list);
  void perf_hpp__reset_output_field(struct perf_hpp_list *list);
  void perf_hpp__append_sort_keys(struct perf_hpp_list *list);

so they could be used on hists's hpp_list.
