From aa3b85fd18d32a49f2e0051ef434d6c16d4a5d18 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 27 Feb 2016 15:30:34 -0500 Subject: [PATCH] nv50,nvc0: bump minimum texture buffer offset alignment It appears that it actually needs to be aligned to the datum size, so it was 1 when testing with R8, but it can be as high as 16 with RGBA32.
