- Console Splitter Driver. Any Handle that attatched\r
- EFI_CONSOLE_IDENTIFIER_PROTOCOL can be bound by this driver.\r
-\r
- So far it works like any other driver by opening a SimpleTextIn and/or\r
- SimpleTextOut protocol with EFI_OPEN_PROTOCOL_BY_DRIVER attributes. The big\r
- difference is this driver does not layer a protocol on the passed in\r
- handle, or construct a child handle like a standard device or bus driver.\r
- This driver produces three virtual handles as children, one for console input\r
- splitter, one for console output splitter and one for error output splitter.\r
- EFI_CONSOLE_SPLIT_PROTOCOL will be attatched onto each virtual handle to\r
- identify the splitter type.\r
-\r
- Each virtual handle, that supports both the EFI_CONSOLE_SPLIT_PROTOCOL\r
- and Console I/O protocol, will be produced in the driver entry point.\r
- The virtual handle are added on driver entry and never removed.\r
- Such design ensures sytem function well during none console device situation.\r
