- * The backend GART interface. (In our case AGP). Any similar type of device (PCIE?)
- * needs only to implement these functions to be usable with the "TTM" interface.
- * The AGP backend implementation lives in drm_agpsupport.c
- * basically maps these calls to available functions in agpgart. Each drm device driver gets an
- * additional function pointer that creates these types,
- * so that the device can choose the correct aperture.
- * (Multiple AGP apertures, etc.)
- * Most device drivers will let this point to the standard AGP implementation.
