From 32dd8d59b6d1b6828e16e854d589d0f04536da14 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 1 Mar 2017 11:09:30 -0500 Subject: [PATCH] nvc0: increase alignment to 256 for texture buffers on fermi When binding as textures, the alignment can be 16. However when binding as an image, the address has to be aligned to 256. (Also when binding as an RT, but that can't happen with GL or current gallium APIs.)
