From 195fedccf07b909c95e5905c7154c595bb260fc7 Mon Sep 17 00:00:00 2001 From: Yuri Kunde Schlesner Date: Sun, 6 Dec 2015 19:06:12 -0800 Subject: VideoCore: Unify interface to OpenGL and SW rasterizers This removes explicit checks sprinkled all over the codebase to instead just have the SW rasterizer expose an implementation with no-ops for most operations. --- src/video_core/rasterizer_interface.h | 48 +++++++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 src/video_core/rasterizer_interface.h (limited to 'src/video_core/rasterizer_interface.h') diff --git a/src/video_core/rasterizer_interface.h b/src/video_core/rasterizer_interface.h new file mode 100644 index 000000000..008c5827b --- /dev/null +++ b/src/video_core/rasterizer_interface.h @@ -0,0 +1,48 @@ +// Copyright 2015 Citra Emulator Project +// Licensed under GPLv2 or any later version +// Refer to the license.txt file included. + +#pragma once + +#include "common/common_types.h" + +namespace Pica { +namespace Shader { +struct OutputVertex; +} +} + +namespace VideoCore { + +class RasterizerInterface { +public: + virtual ~RasterizerInterface() {} + + /// Initialize API-specific GPU objects + virtual void InitObjects() = 0; + + /// Reset the rasterizer, such as flushing all caches and updating all state + virtual void Reset() = 0; + + /// Queues the primitive formed by the given vertices for rendering + virtual void AddTriangle(const Pica::Shader::OutputVertex& v0, + const Pica::Shader::OutputVertex& v1, + const Pica::Shader::OutputVertex& v2) = 0; + + /// Draw the current batch of triangles + virtual void DrawTriangles() = 0; + + /// Commit the rasterizer's framebuffer contents immediately to the current 3DS memory framebuffer + virtual void FlushFramebuffer() = 0; + + /// Notify rasterizer that the specified PICA register has been changed + virtual void NotifyPicaRegisterChanged(u32 id) = 0; + + /// Notify rasterizer that any caches of the specified region should be flushed to 3DS memory. + virtual void FlushRegion(PAddr addr, u32 size) = 0; + + /// Notify rasterizer that any caches of the specified region should be discraded and reloaded from 3DS memory. + virtual void InvalidateRegion(PAddr addr, u32 size) = 0; +}; + +} -- cgit v1.2.3
