OK, so no other devices in your iommu group?

It's actually the Linux kernel that does the isolation into MMU groups. So as long as your motherboard and processor support VT-d then you're good to go.

I've cross checked the info with a HD4850 and RX 580.

Just guessing here. But I think that this would be the os4 kernel itself.

Yes, I agree. This is the only way forward.

For RadeonHD/RX cards I was suspecting it's a problem with 64 bit BARs and in that case I'm not sure it can be fixed because the pegasos2 is a 32 bit system so there may not be enough space in the memory map to map these even if the PCI controller may support these (which probably it doesn't as I did not expect it to be needed so maybe the Marvell emulation may also need to be checked for this). The X5000 and sam460 may use newer CPUs that at least have larger virtual address spaces which may be needed.

I doubt that this is the issue. I am able to use a Radeon R9 270x in a an old SAM440ep with just a PCI to PCIe bridge.

I've asked what errors you get if you only have ATI 9250 with x-vga=on and no other VGA in the system, I know that does not work but I'd need the errors to find out why as I think that's how it sohuld work and not how you managed to get past it as then it did not work so that may not be a viable work around if the problem is elsewhere.

It will immediately result in a segmentation fault (core dumped) and then Qemu is terminated . So no qemu serial or monitor output.

Radeon 9250 will always result in a segmentation fault. No matter what other display I use (or none at all). And on which bus it is connected.

Sadly it's uknown why pegasos2 can't handle radeonRX/HD over bridges :( Even mA1 can (which is even older).

I was able to start QEMU with sm501 display while the RX 560 was in passed through.

apparently --enable-lto is a gcc option. without it, I can build qemu with CLANG. But so far I do not notice a difference in speed.

Cow3d still runs at 26 fps.

But Cube now runs at 30-50 FPS. Even >80fps when staring at a wall.

GFXBench2D performance improved as well: http://hdrlab.org.nz/benchmark/gfxbench2d/OS/AmigaOS/Result/2655
