- Platform Configuration Database (PCD) Protocol 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 protocol only provide the accessing interfaces for Dynamic-Ex type PCD.
-
- Callers to this protocol must be at a TPL_APPLICATION task priority level.
- 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.
