All four DSC files already include "PiSmmCpuDxeSmm.inf" like this:

  UefiCpuPkg/PiSmmCpuDxeSmm/PiSmmCpuDxeSmm.inf {
    <LibraryClasses>
      ...
  }

Given that this new library class is again exclusively used by
PiSmmCpuDxeSmm, can you please resolve this lib class too in module
scope only?

Thanks!
Laszlo

Re: [edk2-devel] [PATCH v3 4/6] OvmfPkg: Specifies SmmCpuSyncLib instance
Posted by Ni, Ray 2 years, 1 month ago 
Laszlo,
I like the "local lib override" idea, similar to the C language recommendation to use local variables instead of global ones when possible.

Thanks,
Ray
