Subject: [PATCH v16 08/10] x86: add CMT related MSRs in allowed list
Date: Thu, 25 Sep 2014 18:19:08 +0800 [thread overview]
Message-ID: <1411640350-26155-9-git-send-email-chao.p.peng@linux.intel.com> (raw)
In-Reply-To: <1411640350-26155-1-git-send-email-chao.p.peng@linux.intel.com>
Tool stack will try to access the two MSRs to perform CMT
related operations, thus added them in the allowed list.
