36 | \r | |
ececc2eb | 37 | @param CodeType Indicates the type of status code being reported.\r |
ad1a1798 | 38 | The type EFI_STATUS_CODE_TYPE is defined in "Related Definitions" below.\r |
ececc2eb | 39 | @param Value Describes the current status of a hardware or software entity.\r |
40 | This includes information about the class and subclass that is used to classify the entity\r | |
41 | as well as an operation. For progress codes, the operation is the current activity.\r | |
42 | For error codes, it is the exception. For debug codes, it is not defined at this time.\r | |
43 | Type EFI_STATUS_CODE_VALUE is defined in "Related Definitions" below.\r | |
ad1a1798 | 44 | Specific values are discussed in the Intel? Platform Innovation Framework for EFI Status Code Specification.\r |
ececc2eb | 45 | @param Instance The enumeration of a hardware or software entity within the system.\r |
46 | A system may contain multiple entities that match a class/subclass pairing.\r | |
47 | The instance differentiates between them. An instance of 0 indicates that instance\r | |
ad1a1798 | 48 | information is unavailable, not meaningful, or not relevant. Valid instance numbers start with 1.\r |
ececc2eb | 49 | @param CallerId This optional parameter may be used to identify the caller.\r |
ad1a1798 | 50 | This parameter allows the status code driver to apply different rules to different callers.\r |
ececc2eb | 51 | @param Data This optional parameter may be used to pass additional data.\r |
52 | Type EFI_STATUS_CODE_DATA is defined in "Related Definitions" below.\r | |
53 | The contents of this data type may have additional GUID-specific data. The standard GUIDs and\r | |
ad1a1798 | 54 | their associated data structures are defined in the Intel? Platform Innovation Framework for EFI Status Codes Specification.\r |
