[Mesa-dev] [PATCH] i915: Always emit W on gen3

2017-06-20 Thread ville . syrjala
From: Ville Syrjälä Unlike the older gen2 hardware, gen3 performs perspective correct interpolation even for the primary/secondary colors. To do that it naturally needs us to emit W for the vertices. Currently we emit W only when at least one texture coordinate set gets emitted. This means the i
