Hello all,
This is my first message in this mailing list.
I am a C/C++ programmer with very little knowledge of GUI programming,
so I apologize in advance if my questions are a bit dummy.
I am developing from scratch a multimedia application for Linux, to
run on an Intel Atom/Nvidia ION architecture. I will be using an
embedded Linux distro with framebuffer enabled and DirectFB support.
I did a lot of research on the web and on the DiretcFB wiki, but found
no reference to the Nvidia ION GPU. Maybe because it is too new.
So I would like to ask the following questions:
* Does DirectFB supports the Nvidia ION already?
Not in the public archive.
The latest chip that seems to be supported is the GeForce 4-series, as
can be taken from driver_probe in nvidia.c.
If it is supported, than by a proprietary driver.
If your framebuffer driver functions, then DirectFB will work properly,
but obviously without hardware acceleration.
Assuming it does:
* Will it provide HW acceleration for menus rendering, movements and
other visual effects?
* Will it provide HW acceleration for video decoding? For which video
formats (MPEG2, H.264)?
* What is exactly the NVidia CUDA and how does DirectFB relates to it?
CUDA is a framework to make your GFX processor act as a co-processor,
like e.g. a floating point co-processor back in the old days. Meaning,
you can execute "regular" code on it. DirectFB has nothing to do with
that, it uses the GFX processor for GFX. :)

Thanks for your help.
