Detailed Description

Native Platform Configuration Database (PCD) INFO PPI

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

Different with the EFI_GET_PCD_INFO_PPI defined in PI 1.2.1 specification, the native PCD INFO PPI 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_PPI

typedef struct _GET_PCD_INFO_PPI GET_PCD_INFO_PPI

The forward declaration for GET_PCD_INFO_PPI.

GET_PCD_INFO_PPI_GET_INFO

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

Retrieve additional information associated with a PCD token in the default token space.

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_PPI_GET_INFO_EX

typedef EFI_STATUS(EFIAPI * GET_PCD_INFO_PPI_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_PPI_GET_SKU

typedef UINTN(EFIAPI * GET_PCD_INFO_PPI_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.
