2 | Provides library services to get and set Platform Configuration Database entries.\r | |
3 | \r | |
4 | PCD Library Class provides a PCD usage macro interface for all PCD types.\r | |
5 | It should be included in any module that uses PCD. If a module uses dynamic/dynamicex\r | |
6 | PCD, module should be linked to a PEIM/DXE library instance to access that PCD.\r | |
7 | If a module uses PatchableInModule type PCD, it also needs the library instance to produce\r | |
8 | LibPatchPcdSetPtr() interface. For FeatureFlag/Fixed PCD, the macro interface is\r | |
9 | translated to a variable or macro that is auto-generated by build tool in\r | |
10 | module's autogen.h/autogen.c.\r | |
11 | The PcdGetXX(), PcdSetXX(), PcdToken(), and PcdGetNextTokenSpace() operations are \r | |
12 | only available prior to ExitBootServices(). If access to PCD values are required \r | |
13 | at runtime, then their values must be collected prior to ExitBootServices().\r | |
14 | There are no restrictions on the use of FeaturePcd(), FixedPcdGetXX(),\r | |
15 | PatchPcdGetXX(), and PatchPcdSetXX().\r | |
