I've made so many changes I don't dare continue until I check the current stuff in.
/test/testatomic.c performs absolutely basic tests to show that the function work as expected. Need a second test to do more detailed tests.
/include/SDL_atomic.h provides declarations for all included functions.
/src/atomic/linux/SDL_atomic.c provided all the functions. On a generic built the 64 bit functions work, but they are emulated. On a build for -march=pentium and above the 64 bit functions use native instructions
/src/atomic/dummy/SDL_atomic.c emulates all the operations using SDL_mutex.h.
/src/atomic/win32/SDL_atomic.c is a copy of dummy
/src/atomic/macosx/SDL_atomic.s is a copy of dummy
These versions of SDL_atomic.c provide a frame work for building the library with a mixture of native and emulated functions. This allows the whole library to be provided on all platforms. (I hope.)
I hope this fits with the SDL philosophy of either providing a common subset or emulating when the platform is missing a feature.
I have not added dummy, macosx, or win32 to the build. They are there as place holders for future work.
I have modified congifure.in to compile sources in /src/atomic/linux. (The SDL configure.in file is an amazing piece of work and I hope I didn't mess it up. :-)

SDL on DirectFB Supports: - Hardware YUV overlays - OpenGL - software only - 2D/3D accelerations (depends on directfb driver) - multiple displays - windows What you need: DirectFB 1.0.1, 1.2.x, 1.3.0 Kernel-Framebuffer support: required: vesafb, radeonfb .... Mesa 7.0.x - optional for OpenGL /etc/directfbrc This file should contain the following lines to make your joystick work and avoid crashes: ------------------------ disable-module=joystick disable-module=cle266 disable-module=cyber5k no-linux-input-grab ------------------------ To disable to use x11 backend when DISPLAY variable is found use export SDL_DIRECTFB_X11_CHECK=0 To disable the use of linux input devices, i.e. multimice/multikeyboard support, use export SDL_DIRECTFB_LINUX_INPUT=0 To use hardware accelerated YUV-overlays for YUV-textures, use: export SDL_DIRECTFB_YUV_DIRECT=1 This is disabled by default. It will only support one YUV texture, namely the first. Every other YUV texture will be rendered in software. In addition, you may use (directfb-1.2.x) export SDL_DIRECTFB_YUV_UNDERLAY=1 to make the YUV texture an underlay. This will make the cursor to be shown. Simple Window Manager ===================== The driver has support for a very, very basic window manager you may want to use when runnning with "wm=default". Use export SDL_DIRECTFB_WM=1 to enable basic window borders. In order to have the window title rendered, you need to have the following font installed: /usr/share/fonts/truetype/freefont/FreeSans.ttf OPENGL Support ============== As of this writing 20070810 you need to pull Mesa from git and do the following: ------------------------ cd mesa make linux-directfb make echo Installing - please enter sudo pw. sudo make install INSTALL_DIR=/usr/local/dfb_GL cd src/mesa/drivers/directfb make sudo make install INSTALL_DIR=/usr/local/dfb_GL ------------------------ To run the SDL - testprograms: export SDL_VIDEODRIVER=directfb export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7 ./testgl
