ad1a1798 | 20 | @param CodeType Indicates the type of status code being reported. Type EFI_STATUS_CODE_TYPE is defined in "Related Definitions" below.\r |
ececc2eb | 21 | \r |
22 | @param Value Describes the current status of a hardware or software entity.\r | |
23 | This included information about the class and subclass that is used to classify the entity\r | |
24 | as well as an operation. For progress codes, the operation is the current activity.\r | |
25 | For error codes, it is the exception. For debug codes, it is not defined at this time.\r | |
26 | Type EFI_STATUS_CODE_VALUE is defined in "Related Definitions" below.\r | |
ad1a1798 | 27 | Specific values are discussed in the Intel? Platform Innovation Framework for EFI Status Code Specification.\r |
ececc2eb | 28 | \r |
29 | @param Instance The enumeration of a hardware or software entity within the system.\r | |
30 | A system may contain multiple entities that match a class/subclass pairing.\r | |
31 | The instance differentiates between them. An instance of 0 indicates that instance information is unavailable,\r | |
ad1a1798 | 32 | not meaningful, or not relevant. Valid instance numbers start with 1.\r |
33 | \r | |
34 | \r | |
ececc2eb | 35 | @param CallerId This optional parameter may be used to identify the caller.\r |
36 | This parameter allows the status code driver to apply different rules to different callers.\r | |
8a7d75b0 | 37 | Type EFI_GUID is defined in InstallProtocolInterface() in the UEFI 2.0 Specification.\r |
ad1a1798 | 38 | \r |
39 | \r | |
40 | @param Data This optional parameter may be used to pass additional data\r | |
