Report status code into GUID'ed HOB.
|

|
|
This function reports status code into GUID'ed HOB. If not all packets are full, then
|
|
write status code into available entry. Otherwise, create a new packet for it.
|
|
|
|
@param PeiServices An indirect pointer to the EFI_PEI_SERVICES table published by the PEI Foundation.
|
|
@param CodeType Indicates the type of status code being reported.
|
|
@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.
|
|
@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.
|
|
|
|
@retval EFI_SUCCESS The function always return EFI_SUCCESS.
