[edk2-devel] [Patch v3 0/2] UefiCpuPkg/RegisterCpuFeaturesLib: Avoid AP calls PeiServices table
Posted by Dong, Eric 4 years, 8 months ago
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.
