From c9d886c84e4102f7b9c464c704eecb61d37b3df4 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Sun, 7 Jul 2019 20:36:42 -0300 Subject: gl_shader_decompiler: Implement gl_ViewportIndex and gl_Layer in vertex shaders This commit implements gl_ViewportIndex and gl_Layer in vertex and geometry shaders. In the case it's used in a vertex shader, it requires ARB_shader_viewport_layer_array. This extension is available on AMD and Nvidia devices (mesa and proprietary drivers), but not available on Intel on any platform. At the moment of writing this description I don't know if this is a hardware limitation or a driver limitation. In the case that ARB_shader_viewport_layer_array is not available, writes to these registers on a vertex shader are ignored, with the appropriate logging. --- src/video_core/engines/shader_bytecode.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/video_core/engines/shader_bytecode.h') diff --git a/src/video_core/engines/shader_bytecode.h b/src/video_core/engines/shader_bytecode.h index 404d4f5aa..b92921d0f 100644 --- a/src/video_core/engines/shader_bytecode.h +++ b/src/video_core/engines/shader_bytecode.h @@ -78,7 +78,7 @@ union Attribute { constexpr explicit Attribute(u64 value) : value(value) {} enum class Index : u64 { - PointSize = 6, + LayerViewportPointSize = 6, Position = 7, Attribute_0 = 8, Attribute_31 = 39, -- cgit v1.2.3
