From ce24097abe1427463ac300a686e4c36ea07464fc Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 9 Jun 2016 15:08:13 -0700 Subject: [PATCH] isl/state: Don't set SurfacePitch for gen9 1-D textures This field is ignored by the hardware in this case and, on very large 1-D textures, it can end up being larger than the maximum allowed value.
