Hi folks, In physical world, a PCIe switch including one upstream port and several downstream ports is a single physical device, however we treat each port as a device in qemu world. In qemu docs/pcie.txt, we have below statements:
Line 230: Be aware that PCI Express Downstream Ports can't be hot-plugged into Line 231: an existing PCI Express Upstream Port. To my understanding, it implies PCIe downstream ports *can* be hot-plugged into something which is not an existing upstream port. If it is true, how can we do that? AFAIK monitor command device_add can only add one device at a time. Please help to show the truth. Thanks, Heyi
