Proof of concept of a Mediator driver (not OpenPCI) running on the Prometheus.

It is the new voodoo.card from Thomas Richter.

That looks pretty awesome!

I managed to get a USB Ethernet device working with usbpegasus.device on the NEC USB card. Only running at lowspeed USB or "Full Speed" USB, performance is not great at around 100KB/s but at least it works.

Thing is that the voodoo and radeon drivers from elbox are behaving nice, but the THOR one is not.Only 8 bit works in the THOR voodoo driver. 16+ bit screens are elongated on the horizontal axis with weird colors.

Interrupt=Yes hangs the system. Elbox' drivers add the interrupt no problem (they do it standard without tooltype).

What device is that?

Above is under P96 v2.1.

I replaced only the rtg.library with the one from P96 v3 and all is well. Except Interrupt=Yes still does not work.

GrantDirectAccess=Yes disappears the big endian 16 bit modes, but I think that is intended.

This is all under pci.library emulation, so not sure if this is of any use to Thomas Richter :-)

[Thomas Richter]

Sorry to respond, but I need to make a strong statement here: Please do not follow this direction. I understand your good intentions, but I never ever wanted to make a statement that I would support the elbox pci.library as a "good interface" for PCI. It is not. It is a one-vendor "undocumented interface" solution, and undocumented locked interfaces are not advisable as basis for development.

The voodoo driver I published was not intended as a "final solution", it was only assumed as a "thank you" note to the community from which I received hardware, and as a replacement for the buggy Elbox driver. That's it. It is not a final solution, and there is a reason why this does not go into Aminet. Take it as an interim fix, but that is *really all*.

Thus, there will be no further PCI graphics card drivers at the moment. Not before I have a good solution for the PCI expansion, and no, Elbox is *not* a good solution. Not an undocumented interface locked to particular hardware.

OpenPCI might, but the project is dead. There is a castrated Open Source solution which does not help me, and its current interface is too limited to satisfy all my needs. To give you an approximate idea what I consider a good solution:

An extension of the OpenPCI.library (essentially, a new version with an extended interface), plus potentially an included emulation layer to legacy libraries. Maybe that's not the best solution and you have other ideas, but I'm happy to receive ideas, this is really just the beginning.

What does OpenPCI not deliver? It does not deliver access to the Expansion ROM. The voodoo driver needs that, however, to get the settings for the RAM on the card. It does not deliver a transparent interface to MMU windowing (and the pci.library "solution" is kludgy). This needs to interoperate with the rest of the system nicely, not by the hack-and-slash method Elbox "designed". OpenPCI does not deliver access to multiple PCI busses or bridges. Only a single bridge is supported. PCI can do more than that.

Thus, Hedeon, with all the sympathies, and I understand that you want to push forward, but I first need to clean up this PCI mess we have here, and I would prefer to work on a better solution. This will take time. Let's rather first collect forces to get this dirt area cleaned up before caring about drivers.


If you want to help me work on that, your help would be of course greatly appreciated. Testing, writing code, collecting information, there is a long road ahead of this.

D-Link DSB-650TX, just some 10/100 USB Ethernet adapter I had laying around.
I tried a couple of devices (Netgear FA120 and Belkin F4U047) which are identified under Triton as usbasixeth devices but haven't gotten them working yet, they seem to start with Genesis or Miami but can't ping anything.

What CPU/Accelerator are these with?
I just ask because with a Voodoo 3 3000/CSMK2-060, my results are significantly lower.

CSMK2-060 55 MHz. It is 640x480x8.
