-Getting MiniGLX up and running
-------------------------------
-
-It's necessary to do a bit of work to set up an environment to run miniglx.
-
-For the radeon driver, it's necessary to get the right set of kernel
-modules installed before attempting to run any programs:
-
- rmmod radeon agpgart;
- insmod agpgart;
- insmod $(MESA)/src/kernel/radeonfb/radeonfb.o;
- insmod $(MESA)/src/kernel/radeon/radeon.o;
-
-For all drivers, its necessary to reach the compiled libraries, and
-tell MiniGLX where to find it's configuration file:
-
- export LD_LIBRARY_PATH=$(MESA)/lib;
- export MINIGLX_CONF=$(MESA)/lib/miniglx.conf
-
-------------------------------------------------------------
-
-MiniGLX Example Programs
-------------------------
-
-The following programs will work with miniglx:
-
- $(MESA)/tests/miniglx
- $(MESA)/xdemos/glxgears
-
-Thanks to the miniglut stub library, most of the mesa glut demos will
-work. In particular, the following have been tested. (Note there is
-no keyboard or mouse interaction with these demos).
-
- $(MESA)/demos/gears
- $(MESA)/demos/geartrain
- $(MESA)/demos/morph3d
- $(MESA)/demos/isosurf
- $(MESA)/demos/texobj
- $(MESA)/demos/texcyl
- $(MESA)/demos/gloss
- $(MESA)/demos/fire
- $(MESA)/demos/tunnel
- $(MESA)/demos/teapot
- $(MESA)/samples/prim
- $(MESA)/samples/olympic
- $(MESA)/samples/star
- $(MESA)/samples/wave
- ...etc
-
-In fact most of the glut demos seem to work within the constraints of
-having no keyboard/mouse interactivity. Furthermore, the use of the
-glut wrapper means that these programs don't require recompilation to
-run under MiniGLX -- the same binary works with both regular GLX and
-MiniGLX.
-
-
-------------------------------------------------------------
-
-Porting GLX apps to MiniGLX
----------------------------
-
-A quick list of issues encountered in porting existing GLX apps to
-MiniGLX. Listed in no particular order.
-
-1) No input events
-
-MiniGLX doesn't provide an input layer, so any X11 input event
-handling in the existing app will have to be redone for whatever
-input devices exist on the target.
-
-2) No configuration, expose events
-
-Many GLX and Xlib programs wait on an event to ensure the window has
-become visible after being mapped. MiniGLX provides no equivalent
-facility.
-
-3) Different headers
-
-X11/Xlib.h, GL/GLX.h, etc must not be used if the program is being
-compiled against MiniGLX.
-
-The equivalent header is GL/MiniGLX.h.
-
-4) Different library
-
-It may be necessary to link directly against the minGLX libGL.so.
-
-5) Reduced number of Xlib and GLX entrypoints.
-
-By definition (MiniGLX is a subset of GLX), many Xlib and GLX
-entrypoints, structures and macros are not present in MiniGLX. It
-will be necessary to find and eliminate all references to
-non-supported entrypoints.
-
-
----------------------------------------------------------------
-
-Bugs in radeonfb.o -- the radeon framebuffer driver.
-----------------------------------------------------
-
-Several bugs have been found in the radeonfb.o framebuffer driver.
-Most of these are resolved in the version included in the MiniGLX
-sources, but some remain:
-
-1) Occasionally, after entering graphics mode, colors appear 'shifted'
-or 'translated', particularly in higher resolution modes. This is
-definitely a bug in radeonfb.o as this can be provoked even when using
-the software dri driver (fb_dri.so). Importance: High. Workaround:
-Use 800x600 as it seems to be less frequent at this resolution,
-otherwise, restart the application.

- *
- * The Mini GLX interface facilitates OpenGL rendering on embedded devices. The
- * interface is a subset of the GLX interface, plus a minimal set of Xlib-like
- * functions.
- *
- * Programs written to the Mini GLX specification should run unchanged
- * on systems with the X Window System and the GLX extension (after
- * recompilation). The intention is to allow flexibility for
- * prototyping and testing.
- *
- * The files in the src/miniglx/ directory are compiled to build the
- * libGL.so library. This is the library which applications link with.
- * libGL.so in turn, loads the hardware-specific device driver.

- *
- * A fairly complete client/server non-blocking communication
