85ea851e 2# Instance of PCD Library using PCD Protocol.\r
e386b444 3#\r
c92c1790 4# There are two PCD protocols as follows:\r
ec735bb2 5# 1) PCD_PROTOCOL\r
6# It is EDKII implementation which support Dynamic/DynamicEx Pcds.\r
7# 2) EFI_PCD_PROTOCOL\r
8# It is defined by PI specification 1.2, Vol 3 which only support dynamicEx \r
9# type Pcd.\r
85ea851e 10#\r
ec735bb2 11# For dynamicEx type PCD, it is compatible between PCD_PROTOCOL and EFI_PCD_PROTOCOL.\r
12#\r
13# This library instance uses the PCD_PROTOCOL to handle dynamic PCD request and use\r
14# EFI_PCD_PROTOCOL to handle dynamicEx type PCD.\r

16# Note: A driver of type DXE_RUNTIME_DRIVER and DXE_SMM_DRIVER can only use this DxePcdLib \r
17# in their initialization without any issues to access Dynamic and DynamicEx PCD. They can't \r
18# access Dynamic and DynamicEx PCD in the implementation of runtime services and SMI handlers.\r
19# Because EFI_PCD_PROTOCOL is DXE protocol that is not aviable in OS runtime phase. \r
