Function Documentation

EfiSerialStatusCodeInitializeWorker()

EFI_STATUS EfiSerialStatusCodeInitializeWorker

(

VOID

)

Locates Serial I/O Protocol as initialization for serial status code worker.

Return values

EFI_SUCCESS

Serial I/O Protocol is successfully located.

MemoryStatusCodeInitializeWorker()

EFI_STATUS MemoryStatusCodeInitializeWorker

(

VOID

)

Initialize runtime memory status code table as initialization for runtime memory status code worker

Return values

EFI_SUCCESS

Runtime memory status code table successfully initialized.

Create the first memory status code GUID'ed HOB as initialization for memory status code worker.

Return values

EFI_SUCCESS

The GUID'ed HOB is created successfully.

MemoryStatusCodeReportWorker()

EFI_STATUS EFIAPI MemoryStatusCodeReportWorker	(	IN EFI_STATUS_CODE_TYPE	CodeType,
		IN EFI_STATUS_CODE_VALUE	Value,
		IN UINT32	Instance,
		IN EFI_GUID *	CallerId,
		IN EFI_STATUS_CODE_DATA *Data	OPTIONAL
	)

Report status code into runtime memory. If the runtime pool is full, roll back to the first record and overwrite it.

Parameters

CodeType	Indicates the type of status code being reported.
Value	Describes the current status of a hardware or software entity. This included information about the class and subclass that is used to classify the entity as well as an operation.
Instance	The enumeration of a hardware or software entity within the system. Valid instance numbers start with 1.
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.
Data	This optional parameter may be used to pass additional data.

Return values

EFI_SUCCESS

Status code successfully recorded in runtime memory status code table.

SerialStatusCodeReportWorker()

EFI_STATUS EFIAPI SerialStatusCodeReportWorker	(	IN EFI_STATUS_CODE_TYPE	CodeType,
		IN EFI_STATUS_CODE_VALUE	Value,
		IN UINT32	Instance,
		IN EFI_GUID *	CallerId,
		IN EFI_STATUS_CODE_DATA *Data	OPTIONAL
	)

Convert status code value and extended data to readable ASCII string, send string to serial I/O device.

Parameters

CodeType	Indicates the type of status code being reported.
Value	Describes the current status of a hardware or software entity. This included information about the class and subclass that is used to classify the entity as well as an operation.
Instance	The enumeration of a hardware or software entity within the system. Valid instance numbers start with 1.
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.
Data	This optional parameter may be used to pass additional data.

Return values

EFI_SUCCESS	Status code reported to serial I/O successfully.
EFI_DEVICE_ERROR	EFI serial device cannot work after ExitBootService() is called.
EFI_DEVICE_ERROR	EFI serial device cannot work with TPL higher than TPL_CALLBACK.
