From 8baed872126b331aa8d789b78986c0100c6d853a Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 10 May 2014 17:51:21 -0400 Subject: [PATCH] nv50,nvc0: fix blit 3d path for 1d array textures Need to adjust coordinates since the shader receives the array index as depth in z, but the TEX instruction expects it to be the second coordinate for a 1D array texture. This fixes fbo-generatemipmap-array.
