Subject: [PATCH 3/3] show energy consumption info in perf tool
Date: Thu, 26 May 2011 16:34:15 +0800 [thread overview]
Message-ID: <1306398855.2207.156.camel@rui> (raw)
Introduce four new perf software events
PERF_COUNT_SW_PKG_ENERGY
PERF_COUNT_SW_CORE_ENERGY
PERF_COUNT_SW_UNCORE_ENERGY
and
PERF_COUNT_SW_DRAM_ENERGY
To use it, users can run
perf stat -e pkg-energy foo
to get the package energy consumption when running foo.
