system BIOS, or disable this device and log errors.

Hi Helgaas,
Some AMD GPUs have hardware support for graphics SR-IOV.
If the SR-IOV capable GPU is plugged into the SR-IOV incapable
platform. It would cause a problem on PCI resource allocation in
current Linux kernel.
Therefore in order to allow the PF (Physical Function) device of
SR-IOV
resource.
I will send out dmesg log lspci info tomorrow. Thanks.

Hi Alex W,
I don't need the kernel patch anymore. However it looks the kernel could be
improved to handle this more gracefully when PCI resource allocation fail. Do
you have a plan to improve it in kernel PCI code?

Hi Alex,
How do you know "particular this system offers no 64-bit MMIO", from dmesg log?
