From 180f95e29aa8782c019caa64ede2a28d8ab62564 Mon Sep 17 00:00:00 2001 From: OGAWA Hirofumi Date: Sun, 6 Dec 2009 20:08:24 +0900 Subject: perf: Make common SAMPLE_EVENT parser Currently, sample event data is parsed for each commands, and it is assuming that the data is not including other data. (E.g. timechart, trace, etc. can't parse the event if it has PERF_SAMPLE_CALLCHAIN) So, even if we record the superset data for multiple commands at a time, commands can't parse. etc. To fix it, this makes common sample event parser, and use it to parse sample event correctly. (PERF_SAMPLE_READ is unsupported for now though, it seems to be not using.)
