Would you support a new Unified Opensource RTG standart?

Here is the databook on the CL-GD5446 which is in the PicassoIV.

It even has programming examples:

yeah, but since i guess karlos asks about vesa support because of gallium relays on it, these cards are out of question because they lack 3d support. if the new gfx system i to be 3d based (on gallium) that is. might be good solution for classics at least with their slow bus.

I don't think it's a good solution for classic systems, as I think most users would like to retain support for PicassoIV, II, II+, Retinas and other non 3d graphic cards.

talking about a dead horse

7 pages about: galium, cgfx5, p96, aros, vesa ...
but not a single posting from a well known coder saying .. it could be (easily) done

.. a dead horse

Piru and others have said it'll be a lot of work. I think we all understand that. The point of the discussion is, what should it be like. And do we want it?

>A little dig around shows driver code for the following in x.org

If you want search, you need look for drivers for Big Endian Systems.maybe PPC or so.
i look on a link and it include X86 files.

The GD5446 code(PicassoIV) seems like it will compile for ppc linux too. Look in the configure file.

xfree86 (xf86 or x86) is the name of the system regardless of cpu platform.

Two good URLs on GPU coding which I found at the aros-exec.org board:

Understanding GPUs from the ground up

and from the same blog:

Notes about radeon display hardware

This is the source posting on aros-exec:
Two tutorials for coding ATI Radeon drivers

Worth mentioning I think, as he takes a developer step by step in how to initialize a Radeon PCI card on a x86 PCI bus.

The code won't be much help, but the knowhow which he shares is good.
