Subject: [Patch v3 0/2] UefiCpuPkg/RegisterCpuFeaturesLib: Avoid AP calls PeiServices table
Date: Wed, 17 Jul 2019 09:58:58 +0800 [thread overview]
Message-ID: <20190717015900.29224-1-eric.dong@intel.com> (raw)
V3 Changes:
1. Remove IsCpuFeatureMatch function.
V2 Changes:
1. Revert IsBitMaskMatchCheck change which is not correct.
2. refine some variable name.
v1 changes:
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1972
AP calls CollectProcessorData() to collect processor info.
CollectProcessorData function finally calls PcdGetSize function to get DynamicPCD PcdCpuFeaturesSetting value. PcdGetSize will use gBS which caused ASSERT.
This patch serial fixes the issue and enhances the related code to avoid later report this issue again.
