+
+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.

+ * \brief DRI utility functions definitions.
+ *
+ * This module acts as glue between GLX and the actual hardware driver.  A DRI
+ * driver doesn't really \e have to use any of this - it's optional.  But, some
+ * useful stuff is done here that otherwise would have to be duplicated in most
+ * drivers.
+ * 
+ * Basically, these utility functions take care of some of the dirty details of
+ * screen initialization, context creation, context binding, DRM setup, etc.
+ *
+ * These functions are compiled into each DRI driver so libGL.so knows nothing
+ * about them.
+ *
+ * Look for more comments in the dri_util.c file.

+/**
+ * \mainpage Mini GLX
+ *
+ * \section miniglxIntro Introduction
+ *
+ * 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.
+ *

+/**
+ * \page datatypes Notes on the XVisualInfo, Visual, and __GLXvisualConfig data types
+ * 
+ * -# X (unfortunately) has two (or three) data types which
+ *    describe visuals.  Ideally, there would just be one.
+ * -# We need the #__GLXvisualConfig type to augment #XVisualInfo and #Visual
+ *    because we need to describe the GLX-specific attributes of visuals.
+ * -# In this interface there is a one-to-one-to-one correspondence between
+ *    the three types and they're all interconnected.
+ * -# The #XVisualInfo type has a pointer to a #Visual.  The #Visual structure
+ *    (aka MiniGLXVisualRec) has a pointer to the #__GLXvisualConfig.  The
+ *    #Visual structure also has a pointer pointing back to the #XVisualInfo.
+ * -# The #XVisualInfo structure is the only one who's contents are public.
+ * -# The glXChooseVisual() and XGetVisualInfo() are the only functions that
+ *    return #XVisualInfo structures.  They can be freed with XFree(), though
+ *    there is a small memory leak.

+    * upto the first 4 offset pointers point to mipmap levels.  The last
+    * offset pointer tells how large the preceeding mipmap is.  This value is
+    * then used to determine where the remaining mipmaps are.
+    * 
+    * For example, if the first offsets[0] through offsets[2] are used as
+    * pointers, then offset[3] will be the size of the mipmap pointed to by
+    * offsets[2].  So mipmap level 3 will be at (offsets[2]+offsets[3]).  For
+    * each successive mipmap level, offsets[3] is divided by 4 and added to
+    * the previous address.  So mipmap level 4 will be at 
+    * (offsets[2]+offsets[3]+(offsets[3] / 4)).
+    * 
+    * The last pointer is selected by setting TO_texorgoffsetsel in its
+    * pointer.  In the previous example, offset[2] would have
+    * TO_texorgoffsetsel or'ed in before writing it to the hardware.
+    * 
+    * In the current driver all of the mipmaps are packed together linearly
+    * with mipmap level 0.  Therefore offsets[0] points to the base of the
+    * texture (and has TO_texorgoffsetsel or'ed in), and offsets[1] is the
+    * size of the base texture.
+    *
+    * There is a possible optimization available here.  At times the driver
+    * may not be able to allocate a single block of memory for the complete
+    * texture without ejecting some other textures from memory.  It may be
+    * possible to put some of the lower mipmap levels (i.e., the larger
+    * mipmaps) in memory separate from the higher levels.
+    *
+    * The implementation should be fairly obvious, but getting "right" would
+    * likely be non-trivial.  A first allocation for the entire texture would
+    * be attempted with a flag that says "don't eject other textures."  If
+    * that failed, an additional allocation would be attmpted for just the
+    * base map.  The process would repeat with the block of lower maps.  The
+    * tricky parts would be in detecting when some of the levels had been
+    * ejected from texture memory by other textures and preventing the
+    * 4th allocation (for all the smallest mipmap levels) from kicking out
+    * any of the first three.
+    * 
+    * This array holds G400_TEX_MAXLEVELS pointers to remove an if-statement

+
+NOTE:
+
+These files are incomplete.  They do not yet form a working
+implementation of hte concepts discused below.
+
+
+OVERVIEW
+
+The t_dd_imm_* files form a set of templates to produce driver -
+specific software tnl modules for a small subset of transformation and
+lighting states.
+
+The approach is quite different to the large vertex buffers of the
+src/tnl module, and is based around a cache of four recent vertices
+and a 'current' vertex which is updated directly from the Color,
+Normal, Texcoord, SecondaryColor and Fog entrypoints.
+
+The current vertex is actually a composite of the ctx->Current values
+and a partial hardware vertex maintained where the hardware values
+differ from those in ctx->Current.  For example, clamped color values
+are kept in the hardware vertex, while texcoords remain in
+ctx->Current.
+
+A crude diagram:
+
+       		+--------------+	+-------------------+
+		| ctx->Current |	| Current-HW-vertex |
+		+--------------+	+-------------------+
+		       \       	       	       	  /
+		       	\      			 /
+			 \     			/
+			  \    		       /
+			   ---------   --------
+			       	   |   |      
+			       	   v   v     
+	+--------+   +--------+  +--------+  +--------+ 
+	| vert-0 |   | vert-1 |  | vert-2 |  | vert-3 |		       	 
+	+--------+   +--------+  +--------+  +--------+		       	 
+				     |
+				     |
+				     v
+				     
+				    DMA
+
+
+Here values from ctx->Current and current-HW-vertex are merged to
+build vert-2, which is then dumped to hardware (DMA).  A state machine
+determines which vertex is built in turn, and how the vertices are
+used to present primitives to hardware.  These actions all occur
+during a call to Vertex{234}f{v}.
+
+Each vert-n includes clip coordinates and a clipmask in addition to
+the hardware (window) coordinates.  This information allows clipping
+to take place directly on these vertices, if need be.
+
+t_dd_imm_capi.h
+	
+	Color{34}{fub}{v}() implementations.  These update both
+	ctx->Current (unclamped float colors) and current-HW-vertex
+	with hardware-specific color values (typically unsigned
+	bytes).
+
+	When lighting is enabled, the functions from src/api_noop.c
+	should be used, which just update ctx->Current.  (The
+	current-hw-vertex colors are produced from lighting, which is
+	keyed to Normal3f).
+
+t_dd_imm_vb.c
+
+	Support functions for clipping and fallback.  See
+	t_dd_imm_primtmp.h.
+
+t_dd_imm_napi.c
+t_dd_imm_napi.h
+
+	Versions of Normal3f{v} to perform lighting with one or more
+	infinite lights.  Updates ctx->Current.Normal and the current
+	HW colors.
+
+	When lighting is disabled, use the functions from api_noop.c
+	instead.
+
+
+t_dd_imm_primtmp.h
+
+	State machine to control emission of vertices and primitives
+	to hardware.  Called indirectly from Vertex{234}f{v}.  Capable
+	of supporting hardware strip and fan primitives, and of
+	decomposing to discreet primitives for clipping or fallback,
+	or where the native primitive is unavailable.
+
+t_dd_imm_tapi.h
+
+	Implementations of TexCoord{v} and MultiTexCoord4f{v}ARB to
+	fire a callback when transitioning to projective texture.
+	Most drivers will need to change vertex format at this point,
+	some may need to enable a software rasterization fallback.
+
+t_dd_imm_vapi.h
+
+	Implementations of Vertex{234}f{v}.  These perform
+	transformation and cliptesting on their arguments, then jump
+	into the state machine implemented in primtmp.h.
+
+t_dd_imm_vertex.h
+
+	Support functions for building and clip-interpolating hardware
+	vertices.  Called from primtmp.h.
