From 6742434261158ad9678bf15b165304e0200cc324 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sun, 25 Oct 2015 15:51:28 +0100 Subject: perf tools: Add stat config event synthesize function Introduce the perf_event__synthesize_stat_config to synthesize a 'struct perf_stat_config'. Storing the stat config in the form of tag-value pairs will, I believe, sort out future version extensibility issues.
