From 4bcebe10ca322c1237d93a0bb786b91731f90589 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 13 Apr 2017 14:12:28 +1000 Subject: [PATCH] radv: allocate thin textures as linear. This is ported from radeonsi, and avoids the bug in the addrlib code. This should probably be something addrlib does for us, but for now this fixes the regression without changing addrlib and aligns us with radeonsi.
