	This source code  may damage your hardware.
	It is *UNTESTED* and *BROKEN* !
	Or, at least, some of it is.



         R300_DEMO
	  
	      DRM/DRI exercise utility
	      
	 What it does: 
	 
	       r300_demo exercises r300_lib.h and paints various graphics
	       that we know how to do at the moment.
	       
	       The code as is should work on Radeon Mobility M10 chips
	       (using a large enough mode, 1280x1024 will do)
	       
	       It will produce the intended picture as well as some screen 
	       corruption due to DEPTH buffer being allocated in visible 
	       area (for debugging and feedback).
	       	       
	  Requirements:
	  
	        * this package (obviously)
		
		* Radeon DRM driver - patched using one of the patches
		  from http://volodya-project.sf.net/R300.php
	      
	        * Modified ati driver  - so that Xserver initializes
		  DRM driver properly. 
		  
		 DO NOT RUN ANY GL 3D PROGRAMS (like glxgears) WITH THIS PATCH !

		* modify drmtest/drmtest.c to specify correct display_width - 
		  I left it at 1920 which is correct for my hardware

                * You need to be root to run glxtest
		
           If you have R300/RV350 graphics card different from 
	   Radeon Mobility M10 this code might not work for you and 
	   may cause a hard lockup.
