[PATCH v3 08/10] drm/i915: Don't write IVB_FBC_RT_BASE

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

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

We use nuking instead of render tracking on IVB+, so there's
no point in writing IVB_FBC_RT_BASE.

v2: Drop the IVB_FBC_RT_BASE write too
v3: Move the SNB stuff elsewhere, leaving only IVB+ here
