2 Native Platform Configuration Database (PCD) Protocol\r
3\r
4 Different with the EFI_PCD_PROTOCOL defined in PI 1.2 specification, the native\r
5 PCD protocol provide interfaces for dynamic and dynamic-ex type PCD.\r
6 The interfaces in dynamic type PCD do not require the token space guid as parameter,\r
7 but interfaces in dynamic-ex type PCD require token space guid as parameter.\r

29 Sets the SKU value for subsequent calls to set or get PCD token values.\r
30\r
31 SetSku() sets the SKU Id to be used for subsequent calls to set or get PCD values.\r
32 SetSku() is normally called only once by the system.\r
33\r
34 For each item (token), the database can hold a single value that applies to all SKUs,\r
35 or multiple values, where each value is associated with a specific SKU Id. Items with multiple,\r
36 SKU-specific values are called SKU enabled.\r
37\r
38 The SKU Id of zero is reserved as a default. The valid SkuId range is 1 to 255.\r
39 For tokens that are not SKU enabled, the system ignores any set SKU Id and works with the\r
40 single value for that token. For SKU-enabled tokens, the system will use the SKU Id set by the\r
41 last call to SetSku(). If no SKU Id is set or the currently set SKU Id isn't valid for the specified token,\r
42 the system uses the default SKU Id. If the system attempts to use the default SKU Id and no value has been\r
43 set for that Id, the results are unpredictable.\r
44\r
45 @param[in] SkuId The SKU value that will be used when the PCD service will retrieve and\r
46 set values associated with a PCD token.\r
