- Console Splitter Driver. Any Handle that attatched\r

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