Gabriel Jacobo f982d08784 Rearrange documentation

1) Moves all READMEs to docs/
2) Renames them to *.md, adds some Markdown with the idea to add a lot more
3) Moves the doxyfile config to doc/ and makes it parse the headers at ../include as well as the md files in docs.
4) Skips SDL_opengl*.h headers from the docs
5) Minor fixes to doxyfile

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 running 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

The following instructions will give you software OpenGL. However this works at least on all directfb supported platforms.

As of this writing 20100802 you need to pull Mesa from git and do the following:

git clone git://anongit.freedesktop.org/git/mesa/mesa cd mesa git checkout 2c9fdaf7292423c157fc79b5ce43f0f199dd753a

Edit configs/linux-directfb so that the Directories-section looks like

Directories

SRC_DIRS = mesa glu GLU_DIRS = sgi DRIVER_DIRS = directfb PROGRAM_DIRS =

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
