From 162352e6711b3ceab114686f7a3248074339e7f7 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sun, 3 Feb 2019 21:55:12 -0500 Subject: [PATCH] nvc0: fix 3d images on kepler Looks like SUBFM.3D and SUEAU are perfectly capable of dealing with 3d tiling, they just need the correct inputs. Supply them. We also have to deal with the case where a 2d "layer" of a 3d image is bound. In this case, we supply the z coordinate separately to the shader, which has to optionally treat every 2d case as if it could be a slice of a 3d texture.
