Subject: [PATCH 2/3] perf/x86/intel: Add Cannon Lake support of RAPL profiling
Date: Fri, 9 Mar 2018 20:15:47 +0800 [thread overview]
Message-ID: <20180309121549.630-2-harry.pan@intel.com> (raw)
In-Reply-To: <20180309121549.630-1-harry.pan@intel.com>
This patch enables RAPL counters (energy consumption counters)
support for Cannon Lake processors.
ESU and power domains refer to Intel Software Developers' Manual,
Vol. 4, Order No. 335592.
Usage example:
