Subject: [PATCH 1/1] x86/perf/intel/uncore: remove ev_sel_ext bit support for PCU
Date: Sun, 20 Mar 2016 11:58:21 -0700 [thread overview]
Message-ID: <1458500301-3594-1-git-send-email-kan.liang@intel.com> (raw)
From: Kan Liang <kan.liang@intel.com>
The ev_sel_ext in PCU_MSR_PMON_CTL is locked. So there could be #GP if
writing that bit to 1. Also there is no public events which use the bit.
This patch removes ev_sel_ext bit support for PCU.
