Subject: [PATCH v3] UefiCpuPkg: Fix bug in MpInitLib
Date: Fri, 28 Feb 2020 12:58:02 -0600 [thread overview]
Message-ID: <1582916283-29137-1-git-send-email-leo.duran@amd.com> (raw)
This patch fixes an issue introduced recently in MpInitLib, where we read
a PlatformId MSR that is not implemented on AMD processors. The patch uses
CPUID signature check to skip reading the PlatformId MSR.
Changes since v2:
Fix typo (PCD name) on commit log.
Leo Duran (1):
UefiCpuPkg/MpInitLib: Skip reading PlatformId on AMD processors.
