From d0dd74e853a0a6f37e8061d6d50be41c7034c54c Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 21 Jan 2011 13:46:41 -0200 Subject: [PATCH] perf tools: Move event__parse_sample to evsel.c To avoid linking more stuff in the python binding I'm working on, future csets will make the sample type be taken from the evsel itself, but for that we need to first have one file per cpu and per sample_type, not a single perf.data file.
