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