[Mesa-dev] [PATCH v2 6/6] i965: emit BRW_NEW_AUX_STATE for textures without unresolved colors

[Iago Toral Quiroga]

intel_miptree_texture_aux_usage() will report ISL_AUX_USAGE_NONE for
textures that have a fast clear surface when they have been fully
resolved in order to avoid unnecesary aux surface lookups and save
bandwidth. In this case we want to signal new AUX state so we update
the surface state accordingly.
