fc753d3b 2 Console Splitter Driver. Any Handle that attatched console I/O protocols\r
3 (Console In device, Console Out device, Console Error device, Simple Pointer\r
4 protocol, Absolute Pointer protocol) can be bound by this driver.\r
95276127 5\r
6 So far it works like any other driver by opening a SimpleTextIn and/or\r
7 SimpleTextOut protocol with EFI_OPEN_PROTOCOL_BY_DRIVER attributes. The big\r
8 difference is this driver does not layer a protocol on the passed in\r
9 handle, or construct a child handle like a standard device or bus driver.\r
10 This driver produces three virtual handles as children, one for console input\r
11 splitter, one for console output splitter and one for error output splitter.\r
fc753d3b 12 These 3 virtual handles would be installed on gST.\r
95276127 13\r
fc753d3b 14 Each virtual handle, that supports the Console I/O protocol, will be produced\r
c33add67 15 in the driver entry point. The virtual handle are added on driver entry and\r
16 never removed. Such design ensures sytem function well during none console\r
fc753d3b 17 device situation.\r
