From aef810ec4e6b638facb6c81803c019906f34f014 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 25 Feb 2016 00:13:34 +0900 Subject: perf hists: Basic support of hierarchical report view In the hierarchical view, entries will be grouped and sorted on the first key, and then on the second key, and so on. Add the he->hroot_{in,out} fields to keep the lower level entries. Actually this can share space, in a union, with callchain's 'sorted_root' since the hroots are only used by non-leaf entries and callchain is only used by leaf entries. It also adds the 'parent_he' and 'depth' fields which can be used by browsers. This patch only implements collapsing part which creates internal entries for each sort key. These need to be sorted by output_sort stage and to be displayed properly in the later patch(es).
