Subject: [PATCH 4/5] perf_counter: PERF_RECORD_CONFIG
Date: Fri, 08 May 2009 18:52:23 +0200 [thread overview]
Message-ID: <20090508170028.923228280@chello.nl> (raw)
In-Reply-To: 20090508165219.469818319@chello.nl
[-- Attachment #1: perf_counter-config.patch --]
[-- Type: text/plain, Size: 1843 bytes --]
Much like CONFIG_RECORD_GROUP records the hw_event.config to identify the
values, allow to record this for all counters.
