The purpose of the gtt structure is to help isolate our gtt specific properties from the rest of the code (in doing so it help us finish the isolation from the AGP connection). The following members are pulled out (and renamed): gtt_start gtt_total gtt_mappable_end gtt_mappable gtt_base_addr gsm The gtt structure will serve as a nice place to put gen specific gtt routines in upcoming patches. As far as what else I feel belongs in this structure: it is meant to encapsulate the GTT's physical properties. This is why I've not added fields which track various drm_mm properties, or things like gtt_mtrr (which is itself a pretty transient field).
