33 | @param PeiServices\r | |
34 | \r | |
35 | @param CodeType Indicates the type of status code being reported.\r | |
36 | The type EFI_STATUS_CODE_TYPE is defined in "Related Definitions" below.\r | |
37 | @param Value Describes the current status of a hardware or software entity.\r | |
38 | This includes information about the class and subclass that is used to classify the entity\r | |
39 | as well as an operation. For progress codes, the operation is the current activity.\r | |
40 | For error codes, it is the exception. For debug codes, it is not defined at this time.\r | |
41 | Type EFI_STATUS_CODE_VALUE is defined in "Related Definitions" below.\r | |
42 | Specific values are discussed in the Intel? Platform Innovation Framework for EFI Status Code Specification.\r | |
43 | @param Instance The enumeration of a hardware or software entity within the system.\r | |
44 | A system may contain multiple entities that match a class/subclass pairing.\r | |
45 | The instance differentiates between them. An instance of 0 indicates that instance\r | |
46 | information is unavailable, not meaningful, or not relevant. Valid instance numbers start with 1.\r | |
47 | @param CallerId This optional parameter may be used to identify the caller.\r | |
48 | This parameter allows the status code driver to apply different rules to different callers.\r | |
49 | @param Data This optional parameter may be used to pass additional data.\r | |
50 | Type EFI_STATUS_CODE_DATA is defined in "Related Definitions" below.\r | |
51 | The contents of this data type may have additional GUID-specific data. The standard GUIDs and\r | |
52 | their associated data structures are defined in the Intel? Platform Innovation Framework for EFI Status Codes Specification.\r | |
53 | \r | |
54 | @return Always return EFI_SUCCESS.\r | |
