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/renderer_opengl/gl_device.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'src/video_core/renderer_opengl/gl_device.h') diff --git a/src/video_core/renderer_opengl/gl_device.h b/src/video_core/renderer_opengl/gl_device.h index 8c8c93760..7a3a0675b 100644 --- a/src/video_core/renderer_opengl/gl_device.h +++ b/src/video_core/renderer_opengl/gl_device.h @@ -26,6 +26,10 @@ public: return max_varyings; } + bool HasVertexViewportLayer() const { + return has_vertex_viewport_layer; + } + bool HasVariableAoffi() const { return has_variable_aoffi; } @@ -41,6 +45,7 @@ private: std::size_t uniform_buffer_alignment{}; u32 max_vertex_attributes{}; u32 max_varyings{}; + bool has_vertex_viewport_layer{}; bool has_variable_aoffi{}; bool has_component_indexing_bug{}; }; -- cgit v1.2.3
