[PATCH 03/13] drm/i915: Remove gtt_mappable_total

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



With the assertion from the previous patch in place, it should be safe
to get rid gtt_mappable_total. Keeps things saner to not have to track
the same info in two places.
