From: Yan, Zheng Date: Tue, 13 Aug 2013 06:29:42 +0000 (+0800) Subject: perf/x86/intel/uncore: Enable EV_SEL_EXT bit for PCU X-Git-Tag: v3.12-rc1~168^3~12 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=77b339bce3e21f7a069447fc25a414b18e36fa2e;p=pandora-kernel.git perf/x86/intel/uncore: Enable EV_SEL_EXT bit for PCU 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.
