slouken@7222: SDL on DirectFB
slouken@7222: 
slouken@7222: Supports:
slouken@7222: 
slouken@7222: - Hardware YUV overlays
slouken@7222: - OpenGL - software only
slouken@7222: - 2D/3D accelerations (depends on directfb driver)
slouken@7222: - multiple displays
slouken@7222: - windows
slouken@7222: 
slouken@7222: What you need:
slouken@7222: 
slouken@7222: DirectFB 1.0.1, 1.2.x, 1.3.0
slouken@7222: Kernel-Framebuffer support: required: vesafb, radeonfb .... 
philipp@7241: Mesa 7.0.x	   - optional for OpenGL
slouken@7222: 
slouken@7222: /etc/directfbrc
slouken@7222: 
slouken@7222: This file should contain the following lines to make
slouken@7222: your joystick work and avoid crashes:
slouken@7222: ------------------------
slouken@7222: disable-module=joystick
slouken@7222: disable-module=cle266
slouken@7222: disable-module=cyber5k
slouken@7222: no-linux-input-grab
slouken@7222: ------------------------
slouken@7222: 
slouken@7222: To disable to use x11 backend when DISPLAY variable is found use
slouken@7222: 
slouken@7222: export SDL_DIRECTFB_X11_CHECK=0
slouken@7222: 
slouken@7222: To disable the use of linux input devices, i.e. multimice/multikeyboard support,
slouken@7222: use
slouken@7222: 
slouken@7222: export SDL_DIRECTFB_LINUX_INPUT=0
slouken@7222: 
slouken@7222: To use hardware accelerated YUV-overlays for YUV-textures, use:
slouken@7222: 
slouken@7222: export SDL_DIRECTFB_YUV_DIRECT=1
slouken@7222: 
slouken@7222: This is disabled by default. It will only support one 
slouken@7222: YUV texture, namely the first. Every other YUV texture will be
slouken@7222: rendered in software.
slouken@7222: 
slouken@7222: In addition, you may use (directfb-1.2.x)
slouken@7222: 
slouken@7222: export SDL_DIRECTFB_YUV_UNDERLAY=1
slouken@7222: 
slouken@7222: to make the YUV texture an underlay. This will make the cursor to
slouken@7222: be shown.
slouken@7222: 
slouken@7222: Simple Window Manager
slouken@7222: =====================
slouken@7222: 
slouken@7222: The driver has support for a very, very basic window manager you may
slouken@7222: want to use when running with "wm=default". Use
slouken@7222: 
slouken@7222: export SDL_DIRECTFB_WM=1
slouken@7222: 
slouken@7222: to enable basic window borders. In order to have the window title rendered,
slouken@7222: you need to have the following font installed:
slouken@7222: 
slouken@7222: /usr/share/fonts/truetype/freefont/FreeSans.ttf
slouken@7222: 
slouken@7222: OpenGL Support
slouken@7222: ==============
slouken@7222: 
slouken@7222: The following instructions will give you *software* OpenGL. However this
slouken@7222: works at least on all directfb supported platforms.
slouken@7222: 
slouken@7222: As of this writing 20100802 you need to pull Mesa from git and do the following:
slouken@7222: 
slouken@7222: ------------------------
slouken@7222: git clone git://anongit.freedesktop.org/git/mesa/mesa
slouken@7222: cd mesa 
slouken@7222: git checkout 2c9fdaf7292423c157fc79b5ce43f0f199dd753a
slouken@7222: ------------------------
slouken@7222: 
slouken@7222: Edit configs/linux-directfb so that the Directories-section looks like
slouken@7222: ------------------------
slouken@7222: # Directories
slouken@7222: SRC_DIRS     = mesa glu 
slouken@7222: GLU_DIRS     = sgi
slouken@7222: DRIVER_DIRS  = directfb
slouken@7222: PROGRAM_DIRS = 
slouken@7222: ------------------------
slouken@7222: 
slouken@7222: make linux-directfb
slouken@7222: make
slouken@7222: 
slouken@7222: echo Installing - please enter sudo pw.
slouken@7222: 
slouken@7222: sudo make install INSTALL_DIR=/usr/local/dfb_GL
slouken@7222: cd src/mesa/drivers/directfb
slouken@7222: make
slouken@7222: sudo make install INSTALL_DIR=/usr/local/dfb_GL
slouken@7222: ------------------------
slouken@7222: 
slouken@7222: To run the SDL - testprograms:
slouken@7222: 
slouken@7222: export SDL_VIDEODRIVER=directfb
slouken@7222: export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib
slouken@7222: export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7
slouken@7222: 
slouken@7222: ./testgl
