ASRock Rack Ampere bundle - #40 by Civiloid - starting from here and down.
Yes, in my case, it was recognised as a PCI device out of the box; just the driver was OOPSing.

Also the open source NVIDIA driver: NVIDIA Releases Open-Source GPU Kernel Modules | NVIDIA Technical Blog
a quick look at the mmap syscall and I see the mmio size argument is 0:
mmap(NULL, 0, PROT_READ|PROT_WRITE, MAP_SHARED, 3, 0) = -1 EINVAL (Invalid argument)
and using a dirty fix:
flashrom -dirty on Linux 6.1.0-21-arm64 (aarch64)
flashrom is free software, get the source code at https://flashrom.org
Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).

This PCI device is UNTESTED. Please report the 'flashrom -p xxxx' output
to flashrom@flashrom.org if it works for you. Please add the name of your
PCI device to the subject. Thank you for your help!

Found GigaDevice flash chip "GD25Q20(B)" (256 kB, SPI) on ati_spi.
Reading flash... done.```

From what I read, it appears that this NVIDIA open source driver is just a driver that gives access to the GPU for computing purposes. It is not a display driver. So you still need to choose between reverse engineered nouveau drivers, or binary-only drivers.

I managed to port the Erratum PCIE-65 patches:
and get it running with a WX 3100 on v6.19.9:
however, I failed to get an RX 6400 and an RX 9600 XT to work:

Has anyone gone further down this rabbit hole and can help?
Turns out DRM_AMD_DC_FP has been disabled on clang based builds due to a clang bug, which has been resolved now. Therefore, GPUs using DCN weren’t working, while the one using DCE was working. I removed the safeguard:
It’s now running with the RX 6400 and RX 9060 XT. Will report on stability and eventually gaming performance once I managed to further setup things.
I used “those patches” daily on my machines. Between 6.13 and 6.17 they only need refreshing to apply.
RX6700XT works for me.
Too bad that those patches are still needed ;(
I’ve not gotten a kernel newer than 6.14 to boot
