From d612cd1bf80f36023f0918beb74df08f9bca8abd Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 11 Feb 2019 14:22:50 -0800 Subject: [PATCH] iris: Set 3DSTATE_WM::ForceThreadDispatchEnable The Vulkan driver only sets this if color writes are disabled, which is more conservative - but would require us to inspect blend state. (If color writes are enabled, we don't need to force anything, because the internal signal is already correct. But it shouldn't hurt to do so.) --- src/gallium/drivers/iris/iris_state.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/src/gallium/drivers/iris/iris_state.c b/src/gallium/drivers/iris/iris_state.c index 8191141a373..6d75d255eac 100644 --- a/src/gallium/drivers/iris/iris_state.c +++ b/src/gallium/drivers/iris/iris_state.c @@ -4407,6 +4407,10 @@ iris_upload_dirty_render_state(struct iris_context *ice, wm.EarlyDepthStencilControl = EDSC_PREPS; else if (wm_prog_data->has_side_effects) wm.EarlyDepthStencilControl = EDSC_PSEXEC; + + /* We could skip this bit if color writes are enabled. */ + if (wm_prog_data->has_side_effects || wm_prog_data->uses_kill) + wm.ForceThreadDispatchEnable = ForceON; } iris_emit_merge(batch, cso->wm, dynamic_wm, ARRAY_SIZE(cso->wm)); } -- 2.30.2
