From c910ec5dcf777386641a3c9491d3a430e32a32b1 Mon Sep 17 00:00:00 2001 From: johndoe6345789 Date: Mon, 5 Jan 2026 19:00:35 +0000 Subject: [PATCH] Implement Vulkan Graphics Backend and Interfaces - Added VulkanGraphicsBackend class for Vulkan rendering implementation. - Created IGraphicsBackend interface for abstracted rendering operations. - Introduced GraphicsConfig structure for graphics service configuration. - Updated graphics_types.hpp with new configuration options. - Implemented Vulkan backend initialization, device management, and rendering methods. - Added tests for GXM Graphics Backend to validate functionality. - Refactored existing graphics service interface to support backend-agnostic design. --- .vscode/c_cpp_properties.json | 20 + CMakeLists.txt | 58 +- config/vita_cube_runtime.json | 75 ++ config/vita_gui_runtime.json | 54 ++ config/vita_soundboard_runtime.json | 70 ++ config/vita_system_config.json | 79 ++ docs/CONFIG_SELECTOR.md | 188 +++++ scripts/config_selector.lua | 211 ++++++ scripts/config_selector_demo.lua | 144 ++++ src/app/service_based_app.cpp | 13 +- src/services/impl/graphics_service.cpp | 115 +-- src/services/impl/graphics_service.hpp | 41 +- src/services/impl/gxm_graphics_backend.cpp | 602 +++++++++++++++ src/services/impl/gxm_graphics_backend.hpp | 81 +++ .../impl/render_coordinator_service.cpp | 6 +- src/services/impl/vulkan_graphics_backend.cpp | 193 +++++ src/services/impl/vulkan_graphics_backend.hpp | 70 ++ .../impl/vulkan_graphics_backend_old.cpp | 688 ++++++++++++++++++ src/services/interfaces/graphics_types.hpp | 10 + .../interfaces/i_graphics_backend.hpp | 150 ++++ .../interfaces/i_graphics_service.hpp | 59 +- tests/test_cube_script.cpp | 3 + tests/test_gxm_backend.cpp | 103 +++ 23 files changed, 2908 insertions(+), 125 deletions(-) create mode 100644 .vscode/c_cpp_properties.json create mode 100644 config/vita_cube_runtime.json create mode 100644 config/vita_gui_runtime.json create mode 100644 config/vita_soundboard_runtime.json create mode 100644 config/vita_system_config.json create mode 100644 docs/CONFIG_SELECTOR.md create mode 100644 scripts/config_selector.lua create mode 100644 scripts/config_selector_demo.lua create mode 100644 src/services/impl/gxm_graphics_backend.cpp create mode 100644 src/services/impl/gxm_graphics_backend.hpp create mode 100644 src/services/impl/vulkan_graphics_backend.cpp create mode 100644 src/services/impl/vulkan_graphics_backend.hpp create mode 100644 src/services/impl/vulkan_graphics_backend_old.cpp create mode 100644 src/services/interfaces/i_graphics_backend.hpp create mode 100644 tests/test_gxm_backend.cpp diff --git a/.vscode/c_cpp_properties.json b/.vscode/c_cpp_properties.json new file mode 100644 index 0000000..545cddd --- /dev/null +++ b/.vscode/c_cpp_properties.json @@ -0,0 +1,20 @@ +{ + "configurations": [ + { + "name": "Linux", + "includePath": [ + "${workspaceFolder}/**", + "/usr/local/vitasdk/arm-vita-eabi/include/psp2", + "/usr/local/vitasdk/arm-vita-eabi/include/vitasdk", + "/usr/local/vitasdk/arm-vita-eabi/include" + ], + "defines": [], + "compilerPath": "/usr/bin/clang", + "cStandard": "c17", + "cppStandard": "c++17", + "intelliSenseMode": "linux-clang-x64", + "configurationProvider": "ms-vscode.cmake-tools" + } + ], + "version": 4 +} \ No newline at end of file diff --git a/CMakeLists.txt b/CMakeLists.txt index 94f3367..790d75a 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -5,6 +5,11 @@ if(ENABLE_VITA) message(FATAL_ERROR "VITASDK environment variable must be set when ENABLE_VITA is ON") endif() set(CMAKE_TOOLCHAIN_FILE "$ENV{VITASDK}/share/vita.toolchain.cmake" CACHE FILEPATH "Vita SDK toolchain" FORCE) + include_directories("$ENV{VITASDK}/arm-vita-eabi/include") + link_directories("$ENV{VITASDK}/arm-vita-eabi/lib") + # Disable SDL3 app when building for Vita + set(BUILD_SDL3_APP OFF CACHE BOOL "Build the SDL3 Vulkan demo" FORCE) + set(BUILD_SCRIPT_TESTS OFF CACHE BOOL "Build script engine tests" FORCE) endif() if(CMAKE_GENERATOR MATCHES "Ninja") if(DEFINED CMAKE_GENERATOR_PLATFORM) @@ -71,7 +76,11 @@ if(BUILD_SDL3_APP AND NOT SDL_VERSION STREQUAL "SDL3") set(BUILD_SDL3_APP OFF CACHE BOOL "Build the SDL3 Vulkan demo" FORCE) endif() -set(CMAKE_CXX_STANDARD 23) +if(ENABLE_VITA) + set(CMAKE_CXX_STANDARD 17) +else() + set(CMAKE_CXX_STANDARD 23) +endif() set(CMAKE_CXX_STANDARD_REQUIRED ON) set(CMAKE_CXX_EXTENSIONS OFF) @@ -119,6 +128,7 @@ else() message(FATAL_ERROR "Invalid SDL_VERSION: ${SDL_VERSION}.
