From 090fd3fefab9ef251e6e5bf4011280a657340f2a Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Sat, 4 Apr 2020 02:54:55 -0300 Subject: buffer_cache: Return handles instead of pointer to handles The original idea of returning pointers is that handles can be moved. The problem is that the implementation didn't take that in mind and made everything harder to work with. This commit drops pointer to handles and returns the handles themselves. While it is still true that handles can be invalidated, this way we get an old handle instead of a dangling pointer. This problem can be solved in the future with sparse buffers. --- src/video_core/renderer_opengl/gl_rasterizer.cpp | 39 +++++++----------------- 1 file changed, 11 insertions(+), 28 deletions(-) (limited to 'src/video_core/renderer_opengl/gl_rasterizer.cpp') diff --git a/src/video_core/renderer_opengl/gl_rasterizer.cpp b/src/video_core/renderer_opengl/gl_rasterizer.cpp index f31d960c7..91abeb9d7 100644 --- a/src/video_core/renderer_opengl/gl_rasterizer.cpp +++ b/src/video_core/renderer_opengl/gl_rasterizer.cpp @@ -188,10 +188,8 @@ void RasterizerOpenGL::SetupVertexBuffer() { ASSERT(end > start); const u64 size = end - start + 1; const auto [vertex_buffer, vertex_buffer_offset] = buffer_cache.UploadMemory(start, size); - - // Bind the vertex array to the buffer at the current offset. - vertex_array_pushbuffer.SetVertexBuffer(static_cast(index), vertex_buffer, - vertex_buffer_offset, vertex_array.stride); + glBindVertexBuffer(static_cast(index), vertex_buffer, vertex_buffer_offset, + vertex_array.stride); } } @@ -222,7 +220,7 @@ GLintptr RasterizerOpenGL::SetupIndexBuffer() { const auto& regs = system.GPU().Maxwell3D().regs; const std::size_t size = CalculateIndexBufferSize(); const auto [buffer, offset] = buffer_cache.UploadMemory(regs.index_array.IndexStart(), size); - vertex_array_pushbuffer.SetIndexBuffer(buffer); + glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, buffer); return offset; } @@ -524,7 +522,6 @@ void RasterizerOpenGL::Draw(bool is_indexed, bool is_instanced) { // Prepare vertex array format.
