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)
