Detailed Description

Native Platform Configuration Database (PCD) INFO PROTOCOL.

The protocol that provides additional information about items that reside in the PCD database.

Different with the EFI_GET_PCD_INFO_PROTOCOL defined in PI 1.2.1 specification, the native PCD INFO PROTOCOL provide interfaces for dynamic and dynamic-ex type PCD. The interfaces for dynamic type PCD do not require the token space guid as parameter, but interfaces for dynamic-ex type PCD require token space guid as parameter.

Typedef Documentation

GET_PCD_INFO_PROTOCOL

typedef struct _GET_PCD_INFO_PROTOCOL GET_PCD_INFO_PROTOCOL

The forward declaration for GET_PCD_INFO_PROTOCOL.

GET_PCD_INFO_PROTOCOL_GET_INFO

typedef EFI_STATUS(EFIAPI * GET_PCD_INFO_PROTOCOL_GET_INFO) (IN UINTN TokenNumber, OUT EFI_PCD_INFO *PcdInfo)

Retrieve additional information associated with a PCD token.

This includes information such as the type of value the TokenNumber is associated with as well as possible human readable name that is associated with the token.

Parameters

[in]	TokenNumber	The PCD token number.
[out]	PcdInfo	The returned information associated with the requested TokenNumber.

Return values

EFI_SUCCESS	The PCD information was returned successfully
EFI_NOT_FOUND	The PCD service could not find the requested token number.

GET_PCD_INFO_PROTOCOL_GET_INFO_EX

typedef EFI_STATUS(EFIAPI * GET_PCD_INFO_PROTOCOL_GET_INFO_EX) (IN CONST EFI_GUID *Guid, IN UINTN TokenNumber, OUT EFI_PCD_INFO *PcdInfo)

Retrieve additional information associated with a PCD token.

This includes information such as the type of value the TokenNumber is associated with as well as possible human readable name that is associated with the token.

Parameters

[in]	Guid	The 128-bit unique value that designates the namespace from which to extract the value.
[in]	TokenNumber	The PCD token number.
[out]	PcdInfo	The returned information associated with the requested TokenNumber.

Return values

EFI_SUCCESS	The PCD information was returned successfully
EFI_NOT_FOUND	The PCD service could not find the requested token number.

GET_PCD_INFO_PROTOCOL_GET_SKU

typedef UINTN(EFIAPI * GET_PCD_INFO_PROTOCOL_GET_SKU) (VOID)

Retrieve the currently set SKU Id.

Returns

The currently set SKU Id. If the platform has not set at a SKU Id, then the default SKU Id value of 0 is returned. If the platform has set a SKU Id, then the currently set SKU Id is returned.
