[Xquartz-dev] Google Summer of Code 2008 query

[Pelle Johansson]

Well, as for planning how it should be done, once an understanding is  
grasped of the source tree, I think it should go something like this.

1) Separate out the tight dependency of the drm library from the  
XF86Dri protocol, from xserver and mesa.

That would be the optimal solution, but requires cooperation with the  
linux/bsd X developers. It they object to this, the alternative is to  
make a fake drm library for OS X, even though the architecture is  
completely different.

2) Implement the server side dri driver.

If I'm correct (Jeremy might fill in here), OS X does not need much  
server side support for DRI. This would be a file implementing the  
same protocol as xserver/hw/xfree86/dri/dri.c, probably based on  
xserver/hw/xquartz/xpr/dri.c.

3) Do the client side driver.

Here I'm getting less knowledgeable at the specifics, someone else  
might que in. But it should be implementing the mesa driver interface,  
and call the functions in OpenGL.framework.
