Console Frame Buffer Drivers

Drivers for frame buffers that are used for the system console must provide interfaces to enable the system to display text on the console. The Oracle Solaris OS provides enhanced visual I/O interfaces to enable the kernel terminal emulator to display text directly on the console frame buffer. This appendix describes how to add the necessary interfaces to a frame buffer driver to enable the driver to interact with the Oracle Solaris kernel terminal emulator.
