2 Console Splitter Driver. Any Handle that attatched
3 EFI_CONSOLE_IDENTIFIER_PROTOCOL can be bound by this driver.
4
5 So far it works like any other driver by opening a SimpleTextIn and/or
6 SimpleTextOut protocol with EFI_OPEN_PROTOCOL_BY_DRIVER attributes. The big
7 difference is this driver does not layer a protocol on the passed in
8 handle, or construct a child handle like a standard device or bus driver.
9 This driver produces three virtual handles as children, one for console input
10 splitter, one for console output splitter and one for error output splitter.
11 EFI_CONSOLE_SPLIT_PROTOCOL will be attatched onto each virtual handle to
12 identify the splitter type.
13
14 Each virtual handle, that supports both the EFI_CONSOLE_SPLIT_PROTOCOL
15 and Console I/O protocol, will be produced in the driver entry point.
16 The virtual handle are added on driver entry and never removed.
17 Such design ensures sytem function well during none console device situation.
