From c86a99adeff3ff3c1d3f2c9ce3ccfa122c54d7c7 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Fri, 15 Jun 2018 17:50:35 +0200 Subject: radv: fix emitting the TCS regs on GFX9 The primitive ID is NULL and this generates an invalid select instruction which crashes because one operand is NULL. This fixes crashes in The Long Journey Home, Quantum Break and Just Cause 3 with DXVK.
