-Module Name:
-
- 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.
