21 Report status code to all supported device.
22 Calls into the workers which dispatches the platform specific
25 @param Type Indicates the type of status code being reported.
26 The type EFI_STATUS_CODE_TYPE is defined in "Related Definitions" below.
27 @param Value Describes the current status of a hardware or software entity.
28 This includes information about the class and subclass that is used to classify the entity
29 as well as an operation. For progress codes, the operation is the current activity.
30 For error codes, it is the exception. For debug codes, it is not defined at this time.
31 Type EFI_STATUS_CODE_VALUE is defined in "Related Definitions" below.
32 Specific values are discussed in the Intel? Platform Innovation Framework for EFI Status Code Specification.
33 @param Instance The enumeration of a hardware or software entity within the system.
34 A system may contain multiple entities that match a class/subclass pairing.
35 The instance differentiates between them. An instance of 0 indicates that instance
36 information is unavailable, not meaningful, or not relevant. Valid instance numbers start with 1.
37 @param CallerId This optional parameter may be used to identify the caller.
38 This parameter allows the status code driver to apply different rules to different callers.
39 @param Data This optional parameter may be used to pass additional data.
40 Type EFI_STATUS_CODE_DATA is defined in "Related Definitions" below.
41 The contents of this data type may have additional GUID-specific data. The standard GUIDs and
42 their associated data structures are defined in the Intel? Platform Innovation Framework for EFI Status Codes Specification.
44 @return Always return EFI_SUCCESS.
