\r
- @param CodeType Indicates the type of status code being reported. Type EFI_STATUS_CODE_TYPE is defined in "Related Definitions" below.\r
- \r
- @param Value Describes the current status of a hardware or software entity. \r
- This included information about the class and subclass that is used to classify the entity \r
- as well as an operation. For progress codes, the operation is the current activity. \r
- For error codes, it is the exception. For debug codes, it is not defined at this time. \r
- Type EFI_STATUS_CODE_VALUE is defined in "Related Definitions" below. \r
- Specific values are discussed in the Intel? Platform Innovation Framework for EFI Status Code Specification.\r
- \r
- @param Instance The enumeration of a hardware or software entity within the system. \r
- A system may contain multiple entities that match a class/subclass pairing. \r
- The instance differentiates between them. An instance of 0 indicates that instance information is unavailable, \r
- not meaningful, or not relevant. Valid instance numbers start with 1.\r
-\r
-\r
- @param CallerId This optional parameter may be used to identify the caller. \r
- This parameter allows the status code driver to apply different rules to different callers. \r
- Type EFI_GUID is defined in InstallProtocolInterface() in the UEFI 2.0 Specification.\r
-\r
-\r
- @param Data This optional parameter may be used to pass additional data\r
- \r
- @retval EFI_SUCCESS Success to report status code to serial I/O.\r
- @retval EFI_DEVICE_ERROR EFI serial device can not work after ExitBootService() is called .\r
