The ScreenManager keeps a list of secondary outputs, each with its own swapchain, recreated after a lost device. Platform code adds, resizes and removes them from any thread through Native_AddOutput() and friends, which take effect at the start of the next frame. Each frame, every output is drawn by the topmost screen that claims it (Screen::renderOutput). EmuScreen claims Game outputs: it presents the game there, laid out for that output, and leaves it out of the backbuffer, where the touch controls and the menus stay. Not in non-buffered mode, which draws straight into the backbuffer. --game-window opens such an output on Mac, with Metal. It's a smoke test for multiple swapchains, and a stand-in for an AirPlay display. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Build instructions ================== See https://github.com/hrydgard/ppsspp/wiki/Build-instructions . Also, for general information, see https://www.ppsspp.org/docs . SDL2 Game Controller Support Notes ================================== For SDL2 game controller support, at least SDL 2.0.4 is required. Under the assets directory is the SDL2 game controller database: gamecontrollerdb.txt. This file contains many known control pad mappings for Windows, Linux and MAC OS. PPSSPPSDL will load this file at start-up and work out how to assign control pad buttons for your control pad. Hot plugging of control pads is also supported. If you control pad has a "Guide" or "Home" button then when pressed, this will trigger the emulator pause menu, thus allowing you to exit the emulator if you wish or load another game from your library. WSL notes ========= Works fine on WSL2 with OpenGL, at least. For more notes, see https://www.ppsspp.org/docs/development/wsl/ . Running with valgrind ===================== Here's an example where we both use suppressions, and generate new ones (that you can then take from suppressions.log and simplify and copy to valgrind-wsl2.supp): > valgrind --suppressions=SDL/valgrind-wsl2.supp --gen-suppressions=all --log-file=suppressions.log build/PPSSPPSDL Running with ASAN ================= ./b.sh --sanitize build/PPSSPPSDL.app/Contents/MacOS/PPSSPPSDL Running with UBSAN ================== ./b.sh --sanitize --sanitizeub UBSAN_OPTIONS=print_stacktrack=true build/PPSSPPSDL.app/Contents/MacOS/PPSSPPSDL
