  }

Runs diagnostics on a controller.

Parameters

This	A pointer to the EFI_DRIVER_DIAGNOSTICS2_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 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 the 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 Null-terminated ASCII string array indicating the language. This is the language of the driver name that the caller is requesting, 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. Language is specified in RFC 4646 language code format.
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 Unicode 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_ACCESS_DENIED	The request for initiating diagnostics was unable to be complete due to some underlying hardware or software state.
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.
