Date: Tue, 13 Aug 2013 14:29:42 +0800 Message-Id: <1376375382-21350-4-git-send-email-zheng.z.yan@intel.com> X-Mailer: git-send-email 1.8.1.4 In-Reply-To: <1376375382-21350-1-git-send-email-zheng.z.yan@intel.com> References: <1376375382-21350-1-git-send-email-zheng.z.yan@intel.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1960 Lines: 48 From: "Yan, Zheng" This patch adds support for the SNB-EP PCU uncore PMU extra_sel_bit (bit 21) which is missing from the documentation in Table-2.75 of Intel Xeon Processor E5-2600 Product Family Uncore Performance Monitoring Guide. It is referred to later in Table-2.81. Without this selection bit explicitly enabled by the kernel, some events such as COREx_TRANSITION_CYCLES do not count correctly.
