Platform Configuration Database (PCD) PPI defined in PI 1.2 Vol3
|
||
|
|
|
||
|
|
A platform database that contains a variety of current platform settings or
|
||
|
|
directives that can be accessed by a driver or application.
|
||
|
|
PI PCD ppi only provide the accessing interfaces for Dynamic-Ex type PCD.
|
||
|
|
|
||
|
|
This is the base PCD service API that provides an abstraction for accessing configuration content in
|
||
|
|
the platform. It a seamless mechanism for extracting information regardless of where the
|
||
|
|
information is stored (such as in Read-only data, or an EFI Variable).
|
||
|
|
This protocol allows access to data through size-granular APIs and provides a mechanism for a
|
||
|
|
firmware component to monitor specific settings and be alerted when a setting is changed.

SetSku() sets the SKU Id to be used for subsequent calls to set or get PCD values. SetSku() is
|
||
|
|
normally called only once by the system.
|
||
|
|
For each item (token), the database can hold a single value that applies to all SKUs, or multiple
|
||
|
|
values, where each value is associated with a specific SKU Id. Items with multiple, SKU-specific
|
||
|
|
values are called SKU enabled.
|
||
|
|
The SKU Id of zero is reserved as a default. The valid SkuId range is 1 to 255. For tokens that are
|
||
|
|
not SKU enabled, the system ignores any set SKU Id and works with the single value for that token.
|
||
|
|
For SKU-enabled tokens, the system will use the SKU Id set by the last call to SetSku(). If no
|
||
|
|
SKU Id is set or the currently set SKU Id isn't valid for the specified token, the system uses the
|
||
|
|
default SKU Id. If the system attempts to use the default SKU Id and no value has been set for that
|

Id, the results are unpredictable.

/**

|
Retrieves the next valid PCD token for a given namespace.
|
||
|
|
|
||
|
|
This provides a means by which to get the next valid token number in a given namespace. This is
|
||
|
|
useful since the PCD infrastructure has a sparse list of token numbers in it, and one cannot a priori
|
||
|
|
know what token numbers are valid in the database.
|
||
|
|
|
||
|
|
@param[in] Guid The 128-bit unique value that designates which namespace to extract the value from.
|
||
|
|
@param[in] TokenNumber A pointer to the PCD token number to use to find the subsequent token number. To
|
||
|
|
retrieve the "first" token, have the pointer reference a TokenNumber value of 0.
|
||
|
|
|
||
|
|
@retval EFI_SUCCESS The PCD service has retrieved the value requested.
|
||
|
|
@retval EFI_NOT_FOUND The PCD service could not find data from the requested token number.

Gets the next valid token namespace for a given namespace. This is useful to traverse the valid

token namespaces on a platform.

@param[in, out] Guid An indirect pointer to EFI_GUID. On input it designates a known token

token namespace on the platform. If *Guid is NULL, then the GUID of the first token
