The Linux path of pci_scan_bus reads /sys/bus/pci/devices/.../class and
skips devices whose base class doesn't match. The macOS (IOKit) path
appended every IOPCIDevice unconditionally, so callers that supplied
base_class to narrow down to e.g. display devices would also get the
audio companion function of a multifunction GPU.
Concretely, an NVIDIA RTX Pro 6000 Blackwell exposes:
10de:2bb1 class 0x030000 (display)
10de:22e8 class 0x040300 (multimedia audio)
A PROBE for base_class=3 returned both. With the sorted() at the end of
pci_scan_bus, 22e8 (audio) came first, so the NV runtime picked the
audio function as device 0 and stalled on RESIZE_BAR.
This mirrors the Linux filter on line 70 using the existing read_prop
helper.

* more deviceless const prerequisites [pr]
* remove that
* arange.contiguous -> arange.clone in tests
arange will become deviceless const soon, update tests where it needs to be a buffer
