From 9df37ddd81f54dd41dc4958055c3a3c9b6840aef Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Mon, 17 Aug 2009 23:07:50 +0200 Subject: [PATCH] perf tools: Record events info also when :record suffix is used. You can enable a counter's PERF_SAMPLE_RAW attribute in two fashions: - using the -R option (every counters get PERF_SAMPLE_RAW) - using the :record suffix in a trace event counter name Currently we record the events info in a trace.info file from perf record when the former method is used but we omit it with the latter. Check both situations.
