Report status code to all supported device.

Calls into the workers which dispatches the platform specific

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