From d797fdc5c5c245fbb05f553e68cb95d962fbdd01 Mon Sep 17 00:00:00 2001 From: Sam Liao Date: Tue, 7 Jun 2011 23:49:46 +0800 Subject: perf tools: Add inverted call graph report support. Add "caller/callee" option to support inverted butterfly report, in the inverted report (with caller option), the call graph start from the callee's ancestor. Users can use such view to catch system's performance bottleneck from a sysprof like view. Using this option with specified sort order like pid gives us high level view of call graph statistics. Also add "-G" alias for inverted call graph.
