[PATCHSET 00/12] perf report: Add support for event group view (v5)

[Namhyung Kim <namhyung@kernel.org>]

Hi,

This is my v5 of event group view support patchset.
For basic idea and usage example, please see my original post [1].

This is mostly for rebasing on acme/perf/core, and report.group config
option is added for those who wants to enable it by default.

You can get this series via my tree at:

git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git  perf/group-v5

Any comments are welcome, thanks,
Namhyung


v4 -> v5:
 * rebase on top of current 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)
