From 96be442b7795a6eb3d50f4061f2b98dddc39aa4d Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 23 Aug 2017 23:15:48 -0400 Subject: [PATCH] nv50/ir: properly set sType for TXF ops to U32 All of the coordinates and LOD args are integers for TXF. This mostly doesn't matter, except for converting into a levelZero=true operation by removing an explicit zero LOD. For the comparison against zero to work properly, the sType of the instruction has to be set correctly.
