@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.
