You have a couple of options: - Create a fixed resource for MMCONF. You could place it at the very top of the range so that it doesn't take up too much of your address space - Allow the resource allocator to allocate the MMCONF range You'd have to be a little careful when it gets set to change the address your PCI functions are using, but it should be doable.
