From: Bas Nieuwenhuizen Date: Tue, 11 Apr 2017 22:37:06 +0000 (+0200) Subject: radv: Use an offset instead of pointers for immutable samplers. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bd91caf86366b88330bc167945512d35cc029db0;p=mesa.git radv: Use an offset instead of pointers for immutable samplers. Makes more sense when we hash the layout for the pipeline cache.
