The global ID for the Driver Diagnostics Protocol as defined in EFI 1.1.

Runs diagnostics on a controller.

Parameters

This	A pointer to the EFI_DRIVER_DIAGNOSTICS_PROTOCOL instance.
ControllerHandle	The handle of the controller to run diagnostics on.
ChildHandle	The handle of the child controller to run diagnostics on This is an optional parameter that may be NULL. It will be NULL for device drivers. It will also be NULL for a bus drivers that wish to run diagnostics on the bus controller. It will not be NULL for a bus driver that wishes to run diagnostics on one of its child controllers.
DiagnosticType	Indicates type of diagnostics to perform on the controller specified by ControllerHandle and ChildHandle. See "Related Definitions" for the list of supported types.
Language	A pointer to a three character ISO 639-2 language identifier. This is the language in which the optional error message should be returned in Buffer, and it must match one of the languages specified in SupportedLanguages. The number of languages supported by a driver is up to the driver writer.
ErrorType	A GUID that defines the format of the data returned in Buffer.
BufferSize	The size, in bytes, of the data returned in Buffer.
Buffer	A buffer that contains a Null-terminated string plus some additional data whose format is defined by ErrorType. Buffer is allocated by this function with AllocatePool(), and it is the caller's responsibility to free it with a call to FreePool().

Return values

EFI_SUCCESS	The controller specified by ControllerHandle and ChildHandle passed the diagnostic.
EFI_INVALID_PARAMETER	ControllerHandle is NULL.
EFI_INVALID_PARAMETER	ChildHandle is not NULL, and it is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER	Language is NULL.
EFI_INVALID_PARAMETER	ErrorType is NULL.
EFI_INVALID_PARAMETER	BufferType is NULL.
EFI_INVALID_PARAMETER	Buffer is NULL.
EFI_UNSUPPORTED	The driver specified by This does not support running diagnostics for the controller specified by ControllerHandle and ChildHandle.
EFI_UNSUPPORTED	The driver specified by This does not support the type of diagnostic specified by DiagnosticType.
EFI_UNSUPPORTED	The driver specified by This does not support the language specified by Language.
EFI_OUT_OF_RESOURCES	There are not enough resources available to complete the diagnostics.
EFI_OUT_OF_RESOURCES	There are not enough resources available to return the status information in ErrorType, BufferSize, and Buffer.
EFI_DEVICE_ERROR	The controller specified by ControllerHandle and ChildHandle did not pass the diagnostic.

Enumerator
EfiDriverDiagnosticTypeStandard	Performs standard diagnostics on the controller.
EfiDriverDiagnosticTypeExtended	This is an optional diagnostic type that performs diagnostics on the controller that may take an extended amount of time to execute.
EfiDriverDiagnosticTypeManufacturing	This is an optional diagnostic type that performs diagnostics on the controller that are suitable for a manufacturing and test environment.
EfiDriverDiagnosticTypeCancel	This is an optional diagnostic type that would only be used in the situation where an EFI_NOT_READY had been returned by a previous call to RunDiagnostics() and there is a desire to cancel the current running diagnostics operation.
