From 56ab8e2aae25efc839daeb56d5922e66d2680aec Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Fri, 7 Jan 2022 13:40:19 +0000 Subject: =?UTF-8?q?soc/intel/common/cpu:=20Use=20SoC=20overrides=20to=20ge?= =?UTF-8?q?t=20CPU=20privilege=C2=A0level?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch implements a SoC overrides to check CPU privilege level as the MSR is not consistent across platforms. For example: On APL/GLK/DNV, it's MSR 0x120 and CNL onwards it's MSR 0x151.
