/**

Runs diagnostics on a controller.
|

|

@param This A pointer to the EFI_DRIVER_DIAGNOSTICS_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 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.
|
||||
@param DiagnosticType Indicates 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 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.
|
||||
@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_INVALID_PARAMETER ControllerHandle is not a valid EFI_HANDLE.
|
||||
@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.
