Subject: [PATCH 1/2] platform/x86: ISST: Allow additional TRL MSRs
Date: Thu,  5 Sep 2019 16:37:47 -0700	[thread overview]
Message-ID: <20190905233748.6822-1-srinivas.pandruvada@linux.intel.com> (raw)

Additional Turbo Ratio Limit (TRL) MSRs are required to get bucket vs core
count relationship. So add them to the list of allowed MSRs.
