## DRI Driver

All DRI drivers are made up of 3 parts: 

   * A DRI aware 2D driver which lives in [[xc/programs/Xserver/hw/xfree86/drivers/|http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/dri/xc/xc/programs/Xserver/hw/xfree86/drivers/]] usually in a file _*_dri.[ch]_. 
   * A DRI aware 3D driver based on Mesa which lives in [[xc/lib/GL/mesa/src/drv/|http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/dri/xc/xc/lib/GL/mesa/src/drv/]] 
   * A kernel module which lives in [[xc/programs/Xserver/hw/xfree86/os-support/linux/drm/|http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/dri/xc/xc/programs/Xserver/hw/xfree86/os-support/linux/drm/]]
