I have a starting point. Is it safe to assume that I can post reasonable questions about the Makefile dependencies as I go along, if necessary? I will do my own research, but I think I will have a few questions along the way. <blockquote cite="mid20071219193229.GD23287@cosmic.amd.com" type="cite"> <pre wrap=""></pre> <blockquote type="cite"> <pre wrap="">Do I need any other information to build a configure script for BSD?

In fact, if you know of a X driver that _does_ build on BSD, then you should be able to bring those scripts over easily. In a perfect world, everything would work everywhere. </pre> </blockquote> Good idea.  Very good idea.  I will start with an existing driver make and compare it with GEODE. <blockquote cite="mid20071219193229.GD23287@cosmic.amd.com" type="cite"> <pre wrap=""> </pre> <blockquote type="cite"> <pre wrap="">One other question. What is the true amount of memory available in the hardware for the graphics? Is it 256K ? </pre> </blockquote> <pre wrap=""> This is a UMA architecture, so the amount of memory available for graphics is specified at boot time by the BIOS or firmware. 256K is very low, 8M is typical for minimal systems, and move up to 16M and beyond for more aggressive systems, depending on the maximum resolution you need and how much buffer space you want to leave for X. As a reference, the largest visible framebuffer that LX supports is 1920x1440 which consumes at most 11.5M with all the bells and whistles turned on. How much buffer space you should have depends on what you want to do (i.e. if you want rotation, you'll need room for an entire shadow framebuffer, if you want video you'll need room for the video buffers, etc, etc).
