IORESOURCE_IO? MMIO is memory.
Yes. But I want to map all PCI devices' IO address to this address space. So I set it to IORESOURCE_IO. Are these devices on the PCI bus or on
the root bus?
They are PCI devices and on the PCI bus.
I am not certain how the allocator handles root vs PCI, which is why I ask. For x86 the CPUs APIC area is reserved and not on the PCI bus.
