Agree.
Yu,
can you please add the UefiCpuLib in [LibraryClasses.IA32, LibraryClasses.X64] instead of [LibraryClasses]?

Please double check, the commit message doesn't pass patch check.
And it looks GetPhysicalAddressBits() is not an API from UefiCpuLib.h since the build failed.

Thanks,
Guo

Mike, Liming,
This patch makes MdeModulePkg depend on UefiCpuPkg.
But according to https://github.com/tianocore/edk2/blob/master/MdeModulePkg/MdeModulePkg.ci.yaml#L49, such dependency is not allowed.

Do you agree to move the UefiCpuLib from UefiCpuPkg to MdePkg? The library header and instance are in following paths:
        https://github.com/tianocore/edk2/blob/master/UefiCpuPkg/Include/Library/UefiCpuLib.h
        https://github.com/tianocore/edk2/tree/master/UefiCpuPkg/Library/BaseUefiCpuLib

Thanks,
Ray

Hi, Mike, Liming,

This patch makes MdeModulePkg depend on UefiCpuPkg.
Ray and me would like to move the UefiCpuLib from UefiCpuPkg to MdePkg, do you agree with it ?

Thanks,
Yu

Subject: RE: [edk2-devel] [PATCH v1 2/7] MdeModulePkg: Invoke GetPhysicalAddressBits() and remove the duplicated code

Mike, Liming,
This patch makes MdeModulePkg depend on UefiCpuPkg.
But according to https://github.com/tianocore/edk2/blob/master/MdeModulePkg/MdeModulePkg.ci.yaml#L49, such dependency is not allowed.

Do you agree to move the UefiCpuLib from UefiCpuPkg to MdePkg? The library header and instance are in following paths:
        https://github.com/tianocore/edk2/blob/master/UefiCpuPkg/Include/Library/UefiCpuLib.h
        https://github.com/tianocore/edk2/tree/master/UefiCpuPkg/Library/BaseUefiCpuLib

Thanks,
Ray

Yu and Ray:
  I review UefiCpuLib. I think they are generic enough (X86 arch) to be
placed in MdePkg.

Mike:
  What's your comments for this proposal?

Thanks
