Mesa glFBDev Driver
1. Introduction
The GLFBDev driver interface allows one to do OpenGL rendering into a
framebuffer managed with the Linux's fbdev interface.
Basically, the programmer uses the fbdev functions to initialize the
graphics hardware and setup the framebuffer.
Then, using a calls to Mesa's glFBDev API functions, one can render
into the framebuffer with the OpenGL API functions.
Note, only software rendering is supported; there is no hardware
acceleration.
The GL/glfbdev.h header file defines the glFBDev interface.
The progs/fbdev/glfbdevtest.c demonstrates how to use the glFBDev interface.

2. Compilation
To compile Mesa with support for the glFBDev interface:
   XXX todo
When compilation is finished look in progs/glfbdev/ for the glfbdevtest demo.
xxx todo
3. Compiling and linking glFBDev programs
xxx todo
4. Running glFBDev programs
First, you need to have a working fbdev environment.
See the
http://www.tldp.org/HOWTO/Framebuffer-HOWTO.htmlFramebuffer Howto
 for information.
Programs must be run with root permission.
