Runs diagnostics on a controller.
@param This A pointer to the EFI_DRIVER_DIAGNOSTICS2_PROTOCOL instance.
@param ControllerHandle The handle of the controller to run diagnostics on.
@param 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.
@param 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.
@param 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.
@param ErrorType A GUID that defines the format of the data returned in Buffer.
@param BufferSize The size, in bytes, of the data returned in Buffer.
@param 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().
@retval EFI_SUCCESS The controller specified by ControllerHandle and
ChildHandle passed the diagnostic.
@retval EFI_ACCESS_DENIED The request for initiating diagnostics was unable
to be complete due to some underlying hardware or
software state.
@retval EFI_INVALID_PARAMETER ControllerHandle is NULL.
@retval EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid EFI_HANDLE.
@retval EFI_INVALID_PARAMETER Language is NULL.
@retval EFI_INVALID_PARAMETER ErrorType is NULL.
@retval EFI_INVALID_PARAMETER BufferType is NULL.
@retval EFI_INVALID_PARAMETER Buffer is NULL.
@retval EFI_UNSUPPORTED The driver specified by This does not support
running diagnostics for the controller specified
by ControllerHandle and ChildHandle.
@retval EFI_UNSUPPORTED The driver specified by This does not support the
type of diagnostic specified by DiagnosticType.
@retval EFI_UNSUPPORTED The driver specified by This does not support the
language specified by Language.
@retval EFI_OUT_OF_RESOURCES There are not enough resources available to complete
the diagnostics.
@retval EFI_OUT_OF_RESOURCES There are not enough resources available to return
the status information in ErrorType, BufferSize,
and Buffer.
@retval EFI_DEVICE_ERROR The controller specified by ControllerHandle and
ChildHandle did not pass the diagnostic.
