- Console Splitter Driver. Any Handle that attatched console I/O protocols
- (Console In device, Console Out device, Console Error device, Simple Pointer
- protocol, Absolute Pointer 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.
- These 3 virtual handles would be installed on gST.
-
- Each virtual handle, that supports the 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.
