PCI core requires the NUMA node for the struct pci_host_bridge.dev to be set by using the pcibus_to_node(struct pci_bus*) API, that on ARM64 systems relies on the struct pci_host_bridge->bus.dev NUMA node. The struct pci_host_bridge.dev NUMA node is then propagated through the PCI device hierarchy as PCI devices (and bridges) are enumerated under it. Therefore, in order to set-up the PCI NUMA hierarchy appropriately, the struct pci_host_bridge->bus.dev NUMA node must be set before core code calls pcibus_to_node(struct pci_bus*) on it so that PCI core can retrieve the NUMA node for the struct pci_host_bridge.dev device and can propagate it through the PCI bus tree. On ARM64 ACPI based systems the struct pci_host_bridge->bus.dev NUMA node can be set-up in pcibios_root_bridge_prepare() by parsing the root bridge ACPI device firmware binding. Add code to the pcibios_root_bridge_prepare() that, when booting with ACPI, parse the root bridge ACPI device companion NUMA binding and set the corresponding struct pci_host_bridge->bus.dev NUMA node appropriately.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
