I assume this is what we normally call "windows" or "apertures" for MMIO access by the CPU? (The specs rarely use those terms either, but they're commonly used in Linux, and the PCIe spec does mention them a couple times.) By "request huge outbound memory," I assume you simply mean the device has a huge BAR, right?
