[PATCH 00/14] perf report: Add support for event group view (v7)

[Namhyung Kim <namhyung@kernel.org>]

Hi,

This is my 7th attempt to enable the event group view for perf report.
For basic idea and usage example, please see my initial post [1].

This version is rebased on the current acme/perf/core and Jiri's multi-
diff patchset [2] and addresses comments from the previous spin.

You can get this via 'perf/group-v7' branch on my tree:

git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Any comments are welcome, thanks,
Namhyung


v6 -> v7:
 * hists__{match,link} changes are merged separately
 * factor out inc_group_count() from parsing group_def (Jiri)
 * add checking for group fields in evlist/evsel (Jiri)
 * check return value of during header processing (Arnaldo)
 * get rid of a temporal array in hpp functions (Arnaldo)
 * convert hpp macros to static inline functions (Jiri)

v5 -> v6:
 * set ->leader alse for leader evsel (Arnaldo)
 * use hists__{match,link} (Arnaldo)

v4 -> v5:
 * rebase onto acme/perf/core

v3 -> v4:
 * patch 1-9 in previous post are merged.
 * add Jiri's Acked-by
 * add report.group config option

v2 -> v3:
 * drop patch 1 since it's merged into acme/perf/core
 * cherry-pick Jiri's hpp changes
 * add missing bswap_32 on reading nr_groups (Jiri)
 * remove perf_evlist__recalc_nr_groups() in favor of list_is_last (Jiri)

v1 -> v2:
 * save group relation to header (Jiri)
