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

 



We don't need 2 separate unions.

Note that this was done intentinoally

    drm/i915: Add a partial GGTT view type

on Tvrtko's request, but without a clear justification. Rotated views
are also not checking for matching paramters in i915_ggtt_view_equal,
which seems like a bug. But this patch here doesn't change that.
