Will any of the R5xx/R6xx cards on AGP 8x work, or are we stuck with PCI?
The impression that I got was that none of the new R5xx/R6xx AGP cards operate at the higher voltage of a 2x slot. I could be wrong of-course. However, the advantage of the PCI cards is that I don't have to swap the card in and out to test it. I can continue using my system via my Radeon 9000, and simply use a KVM to view the results on my X1300.

Would you be interested in any donations of similar cards to round out your R5xx/R6xx collection? I'm thinking RV516-based X1550 and/or RV610-based XT2400 PRO if we are limited to PCI.
I'd happily accept donations of similar cards, so long as they're PCI (for now). I originally tried to get an X1550, but got out-bid. I couldn't justify spending too much on a card that I may never get to do anything.
Now that I have the AtomBIOS parser working, supporting newer cards shouldn't be too hard.
If I were starting from scratch then I would use that one. The old source-code is pretty ugly. However, the new code hasn't bee tested as thoroughly, and my code depends extensively on the old AtomBIOS parser. There is no point in switching.
Feel like releasing it as a part of OpenAmiga.org ? :)
IIRC, writing a Picasso96 driver involves signing an NDA, so I don't think that it can be open-source. I don't have the Picasso96 DDK yet, but I've requested it. The OS4 devs are kind of busy, so I'll give them time to respond.
i didn't know about this work... what say... thanks for your work and your effort ! ^_^. Hope you can have all the help you need to improve moreover your drivers
Once the SAM 440EP flex version is out (the one without onboard gfx) this project will become even more important. These cards will kick the 9250's @ss.
Folks - this is a worthwhile project. Hans has a paypal donation page. Hint.

For sure. I just had a look at the SAM 440EP flex's specifications, and I'm happy to see that there's a 66 MHz slot. That'll provide the graphics card with more bandwidth than standard 33 MHz ports.
BTW, does anyone have an ETA on these flex boards? Their announcement suggests that it was supposed to be out last month. Now would be a good time.
I actually had a look at 3D support on the Pre-R200 cards. I am quite sure it can be done, in fact, there is only one small obstacle I would need to be able to solve in order to write a Warp3D driver/Compositing manager for R300 cards; this would most likely work on R400 and R500 as well, although R600 is quite a bit different.
(edit)Note: Don't go out and buy one just yet though
Seriously, if you do want to contact me write me a mail. You're more likely to get a reply then.
iiuic this will be a driver for PCI powered Radeon cards?
Can i, when your driver is finished, put away my AGP card and use the PCI slot for gfx? (thus having one spare AGP slot?)
Which cards/chip revisions will be covered?
Once it's done, you should be able to put away that AGP card and switch to a RadeonHD card. I have Radeon X1300 and Radeon HD 2400 pro graphics cards and both of those work. Theoretically a Radeon X1550 should work too, but I haven't tested it. In fact, any R5xx/R6xx card should work with it; but good luck plugging other ones in without a PCI-Express slot.
This looks cool! How far off is 3D once 2D is working as with a Radeon9xxx?
No idea how far off 3D drivers will be. I hope that the Friedens (and co.) will get going with a MESA port soon so that we can skip writing a Warp3D driver altogether. One of my reasons for writing this driver is because I want GLSL shaders.

Would it be possible to use the 66MHz slot in the AmigaOne if one removed the AGP card?
It should be possible, but has anyone ever tried this with a different graphics card? I haven't tested it.

Would a fast gfx card be faster in a 66MHz PCI slot than a slower gfx card in an AGPx2 slot?
AGPx2 is like 66MHz DDR IIRC, no? = twice the speed of PCI 66?
I'm guessing that the fast PCI card would be faster under most situations. If a game/app requires a lot of data transfer to the card then the AGP 2x might give an advantage.
