| 2 | # Instance of PCD Library using PCD Protocol.
|
|---|
| 3 | #
|
|---|
| 4 | # There are two PCD protocols as follows:
|
|---|
| 5 | # 1) PCD_PROTOCOL
|
|---|
| 6 | # It is EDKII implementation which support Dynamic/DynamicEx Pcds.
|
|---|
| 7 | # 2) EFI_PCD_PROTOCOL
|
|---|
| 8 | # It is defined by PI specification 1.2, Vol 3 which only support dynamicEx
|
|---|
| 9 | # type Pcd.
|
|---|
| 10 | #
|
|---|
| 11 | # For dynamicEx type PCD, it is compatible between PCD_PROTOCOL and EFI_PCD_PROTOCOL.
|
|---|
| 12 | #
|
|---|
| 13 | # This library instance uses the PCD_PROTOCOL to handle dynamic PCD request and use
|
|---|
| 14 | # EFI_PCD_PROTOCOL to handle dynamicEx type PCD.
|
|---|
| 15 | #
|
|---|
| 16 | # Note: A driver of type DXE_RUNTIME_DRIVER and DXE_SMM_DRIVER can only use this DxePcdLib
|
|---|
| 17 | # in their initialization without any issues to access Dynamic and DynamicEx PCD. They can't
|
|---|
| 18 | # access Dynamic and DynamicEx PCD in the implementation of runtime services and SMI handlers.
|
|---|
| 19 | # Because EFI_PCD_PROTOCOL is DXE protocol that is not aviable in OS runtime phase.
