58 Allows the user to set controller specific options for a controller that a
59 driver is currently managing.
60
61 @param This A pointer to the EFI_DRIVER_CONFIGURATION2_PROTOCOL instance.
62 @param ControllerHandle The handle of the controller to set options on.
63 @param ChildHandle The handle of the child controller to set options on. This
64 is an optional parameter that may be NULL. It will be NULL
65 for device drivers, and for bus drivers that wish to set
66 options for the bus controller. It will not be NULL for a
67 bus driver that wishes to set options for one of its child
68 controllers.
69 @param Language A Null-terminated ASCII string that contains one or more RFC 4646
70 language codes. This is the list of language codes that this
71 protocol supports. The number of languages
72 supported by a driver is up to the driver writer.
73 @param ActionRequired A pointer to the action that the calling agent is required
74 to perform when this function returns. See "Related
75 Definitions" for a list of the actions that the calling
76 agent is required to perform prior to accessing
77 ControllerHandle again.
78
79 @retval EFI_SUCCESS The driver specified by This successfully set the
80 configuration options for the controller specified
81 by ControllerHandle.
82 @retval EFI_INVALID_PARAMETER ControllerHandle is not a valid EFI_HANDLE.
83 @retval EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid EFI_HANDLE.
84 @retval EFI_INVALID_PARAMETER ActionRequired is NULL.
85 @retval EFI_UNSUPPORTED The driver specified by This does not support setting
86 configuration options for the controller specified by
87 ControllerHandle and ChildHandle.
88 @retval EFI_UNSUPPORTED The driver specified by This does not support the
89 language specified by Language.
90 @retval EFI_DEVICE_ERROR A device error occurred while attempting to set the
91 configuration options for the controller specified
92 by ControllerHandle and ChildHandle.
93 @retval EFI_OUT_RESOURCES There are not enough resources available to set the
94 configuration options for the controller specified
95 by ControllerHandle and ChildHandle.
