It's possible to crash QEMU by instantiating this device, with;
$ qemu-system-ppc64 -machine prep -device pcie-pci-bridge
qemu-system-ppc64: qemu/memory.c:1533: memory_region_finalize:
I didn't investigate the root cause.
Thanks for reporting it!
Aleksandr, can you have a look? Maybe we should not compile
the device for ppc arch. (x86 and arm is enough)
I will see what can we do. Is x86 and arm really enough?
Well, I am being selfish, and it works for me lately :).
Seriously speaking, the new generic PCI Express
Port was restricted to x86 and arm for reasons I don't remember.
Since your work has the same scope, the restriction makes sense.
Please grep for CONFIG_PCIE_PORT to convince yourself
and to help coding it.
