-
- Arguments:
- This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
- ControllerHandle - The handle of a controller that the driver specified by
- This is managing. This handle specifies the controller
- whose name is to be returned.
- ChildHandle - The handle of the child controller to retrieve the name
- of. 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 retrieve the name of the
- bus controller. It will not be NULL for a bus driver
- that wishes to retrieve the name of a child controller.
- Language - A pointer to a three character ISO 639-2 language
- identifier. This is the language of the controller name
- that 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

- ControllerName - A pointer to the Unicode string to return. This Unicode
- string is the name of the controller specified by
- ControllerHandle and ChildHandle in the language specified
- by Language from the point of view of the driver specified
- by This.
-
- Returns:
- EFI_SUCCESS - The Unicode string for the user readable name in the
- language specified by Language for the driver
- specified by This was returned in DriverName.
- EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
- EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.
- EFI_INVALID_PARAMETER - Language is NULL.
- EFI_INVALID_PARAMETER - ControllerName is NULL.
- EFI_UNSUPPORTED - The driver specified by This is not currently managing
- the controller specified by ControllerHandle and
- ChildHandle.
- EFI_UNSUPPORTED - The driver specified by This does not support the

- UnixSerialIo.c
-
-Abstract:
-
- Our DriverBinding member functions operate on the handles
- created by the NT Bus driver.
-
- Handle(1) - UnixIo - DevicePath(1)
-
- If a serial port is added to the system this driver creates a new handle.
- The new handle is required, since the serial device must add an UART device
- pathnode.
-
- Handle(2) - SerialIo - DevicePath(1)\UART
-
- The driver then adds a gEfiUnixSerialPortGuid as a protocol to Handle(1).
- The instance data for this protocol is the private data used to create
- Handle(2).
-
- Handle(1) - UnixIo - DevicePath(1) - UnixSerialPort
-
- If the driver is unloaded Handle(2) is removed from the system and
- gEfiUnixSerialPortGuid is removed from Handle(1).
-
- Note: Handle(1) is any handle created by the Win NT Bus driver that is passed
- into the DriverBinding member functions of this driver. This driver requires
- a Handle(1) to contain a UnixIo protocol, a DevicePath protocol, and
- the TypeGuid in the UnixIo must be gEfiUnixSerialPortGuid.
-
- If Handle(1) contains a gEfiUnixSerialPortGuid protocol then the driver is
- loaded on the device.
