Questions regarding Intel i915 and accelerated 2D

SDL Development
1

I am trying to set up an embedded system with an Intel 915 chipset.
This system will require 2D and 3D graphics. I envision using SDL
with X and the Intel 915 driver. I can’t really use DirectFB because
there is not currently a working framebuffer driver for the i915 chipset.

Will this setup (SDL on top of X with the Intel driver) provide me with
accelerated 2D graphics? If not, then is there any way to get
accelerated 2D graphics without writing my own framebuffer driver for
use with DirectFB and SDL?

Any help or info is appreciated.

Thanks,
Dave

Not out of the box.

I suggest you setup OpenGL 3D acceleration for your card, and then use
glSDL (which is accelerated 2D SDL on top of OpenGL).
A version of SDL patched with glSDL is available there :
http://icps.u-strasbg.fr/~marchesin/sdl/SDL12-experimental.tgz
And the glSDL patch is there :

If I might ask, what is the architecture of the embedded
system and development board?

Thanks,

The development board is an Asus P5GD1-VM with a P4. We’re going with
a 2.4 kernel for now.

It’s pretty big as far as embedded systems go. We’re thinking of
around 1GB of RAM and possibly that much for flash.
