[PATCH] drm/i915: MI_PREDICATE_RESULT_2 is HSW only

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

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

The MI_PREDICATE_RESULT_2 register exits only on HSW. On other
platforms the same offset is either reserved, or contains some
other register. So write the register only on HSW.
