From 06f818c932be5e19176db0d50939ee89da3267ad Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Fri, 20 Jul 2018 23:41:54 +0200 Subject: cpu/intel/smm/gen1: Use correct MSR for model_6fx and model_1067x MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit According to the "Intel® 64 and IA-32 Architectures Software Developer’s Manual" the SMRR MSR are at a different offset for model_6fx and model_1067x. This still need SMRR enabled and lock bit set in MSR_FEATURE_CONTROL.
