PI EFI_PEI_PCD_PPI supports DynamicEx PCD. EDKII PCD_PPI supports Dynamic and DynamicEx PCD both.

If no Dynamic PCD usage, PI EFI_PEI_PCD_PPI should be enough.

hi, experts:

I found someone had ever asked this question:

PCD peim will install 2 Ppis:

1. PCD_PPI

2. EFI_PEI_PCD_PPI

 

It seems only EFI_PEI_PCD_PPI follows PI 1.2 Vol3's related definition.

maybe, we just need to install only EFI_PEI_PCD_PPI.

 

Is it for compatible with previous old edkii modules?

 

best wishes,
