84 | @param CodeType Indicates the type of status code being reported. Type EFI_STATUS_CODE_TYPE is defined in "Related Definitions" below.\r | |
85 | \r | |
86 | @param Value Describes the current status of a hardware or software entity.\r | |
87 | This included information about the class and subclass that is used to classify the entity\r | |
88 | as well as an operation. For progress codes, the operation is the current activity.\r | |
89 | For error codes, it is the exception. For debug codes, it is not defined at this time.\r | |
90 | Type EFI_STATUS_CODE_VALUE is defined in "Related Definitions" below.\r | |
91 | Specific values are discussed in the Intel? Platform Innovation Framework for EFI Status Code Specification.\r | |
92 | \r | |
93 | @param Instance The enumeration of a hardware or software entity within the system.\r | |
94 | A system may contain multiple entities that match a class/subclass pairing.\r | |
95 | The instance differentiates between them. An instance of 0 indicates that instance information is unavailable,\r | |
96 | not meaningful, or not relevant. Valid instance numbers start with 1.\r | |
97 | \r | |
98 | \r | |
99 | @param CallerId This optional parameter may be used to identify the caller.\r | |
100 | This parameter allows the status code driver to apply different rules to different callers.\r | |
101 | Type EFI_GUID is defined in InstallProtocolInterface() in the EFI 1.10 Specification.\r | |
102 | \r | |
103 | \r | |
104 | @param Data This optional parameter may be used to pass additional data\r | |
