We'll support full 64 bit addresses starting 2.0. However, note that most hardware (cpus and iommus still dosn't allow full 64 bit addresses). So if you program a 64 bit bar outside the range supported by the CPU, it won't be able to access it, > Moreover, is "PCIE" emulation in QEMU used by any architecture? q35 machine type is using it on x86.
