PCI bus can have multiple levels of switches and bridges. The NUMA information is only present on the host bridge. This code only works if the endpoint is directly connected to the root port. You should follow a similar design pattern like pci_dma_configure() where you go to the host bridge device from any pci device and read the _PXM from the host bridge. -- Sinan Kaya Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
