PCD Library Class provides PCD usage macro interface for all PCD types. It should be
|
|
included at any module who use PCD.
|
|
|
|
If module use dynamic/dynamicex PCD, module should be linked to PEIM/DXE library
|
|
instance to access that PCD.
|
|
If module uses PatchableInModule type PCD, also need library instance produce LibPatchPcdSetPtr()
|
|
interface.
|
|
For FeatureFlag/Fixed PCD, macro interface is translated to an variable or macro
|
|
which is auto-generated by build tool in module's autogen.h/autogen.c
