This check in updates SDL_atomic.h to reflect the new set of atomic operations in 32 and 64 bit form. It also update configure.in to compile the linux version of the library. The three versions are all dummies implementations that do nothing. They are being checked in as place holders. Mostly, I just wanted to get place holders and the configure.in checked in.

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
