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 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 capabl
ce will be
correctly assigned BAR resource and user can use PF device.

trigger some error handler to either just keep original BAR values set by
system BIOS, or disable this device and log errors.

be better. My patch is trying to auto detect and bypass VF resource
allocation.
