Maybe I am blind, but for me the code looks like it is just support for Prometheus PCI bridge included. Where can I find the G-Rex support code?

Saving the code is a good thing, I didn't realize the original OpenPCI wasn't being maintained any longer. Doesn't anyone on the MorphOS and AROS teams do development on it? I thought both were using it as the solution for PCI card expansion.


I'm not sure on either of those.

I think the source was given to the Aros guys at one point and they either modified it a lot or went a different route.

Aros might not be a bad new target if it isn't supported already though. Sharing more drivers and open APIs is never a bad thing for any platform.

I put up exactly what was given to me and at the time I received it, I was intending to support my new PCI backplane with it. (a project I've since put on the backburner in favor of software projects)

I haven't really looked into exactly what is included in this archive beyond what I needed to know at the time.

Semi-related, is there any info on creating an openpci device driver available?  I'd love to have an openpci_8169.device driver so I can replace the 10/100 8139 card I'm using now in my Amithlon system with an 10/100/1000 8169 card I have.

Yes, there has been an SDK available on the original homepage and possibly Aminet as well. That should still work even with a newer OpenPCI.library when available.

I will be uploading that to github as well as adding an additional example driver for the 8139 that makes use of DMA.

That sounds like a great use of the SDK. If you get it completed, please consider making it open source and releasing the code for others to learn from.

I've just changed the license to LGPL at Jason McMullen's suggestion.

There are serious problems with GPL libraries on Amiga-like OSs.

Wasn't OpenPCI also used on amithlon builds?

Yes, OpenPCI could be used for a few devices on Amithlon.  Some PCI sound and network cards and I think a few USB PCI cards.

I used it for a Realtek 8139 PCI card for awhile.

since Prometheus PCI ist opensource, maybe someone want´s to build them new or use parts of it, to create new cards  ?

One reason there may not be much movement around the open Prometheus PCI is that the current firmware is pretty limited and lacks PCI to PCI DMA. I know Michael Böhmer developed a newer version with this capability. I've heard a few people have gotten their Prometheus cards upgraded. If that firmware was released more widely I think there would be some renewed interest. In theory that was going to happen at some point as can be seen here: http://www.e3b.de/prometheus/

Sadly, this was from some time ago so I don't think it is going to happen.

uhhh.... no! I did some Betatesting 2 Years ago for a new .card and .chip driver for the voodoo 3, wich was developed by Matatabs. The reason for this Picasso96 Driver was to ensure, that it works with BOTH Models of the Prometheus PCI (with and without DMA) an there ARE or WERE Plans to setup a new version of the Prometheus by Michael..... but I have no idea about the actual project-status..... Prototypes are existing AFAIK

Maybe we should ask him?
