    drm/i915: Create a gtt structure · 5d4545ae
    Ben Widawsky authored
    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).
