From d38425ce872c4a00cfb691ae9dceca6a07afc516 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Wed, 25 Apr 2018 18:15:52 +0200 Subject: [PATCH] ac: fix texture query LOD for 1D textures on GFX9 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 1D textures are allocated as 2D which means we only need one coordinate for texture query LOD.
