    drm/i915: Build workaround list in ring initialization · 7225342a
    Mika Kuoppala authored
    If we build the workaround list in ring initialization
    and decouple it from the actual writing of values, we
    gain the ability to decide where and how we want to apply
    the values.
    
    The advantage of this will become more clear when
    we need to initialize workarounds on older gens where
    it is not possible to write all the registers through ring
    LRIs.
    
    v2: rebase on newest bdw workarounds
