Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.

The powerpc PCI code requires that a pci_dn structure exists for all devices in the system. This is fine for real devices since at boot a pci_dn is created for each PCI device in the DT and it's fine for hotplugged devices since the hotplug slot driver will manage the pci_dn's devices in hotplug slots. For SR-IOV, we need the platform / pcibios to manage the pci_dn for virtual functions since firmware is unaware of VFs, and they aren't "hot plugged" in the traditional sense. Management of the pci_dn is handled by the, poorly named, functions: add_pci_dev_data() and remove_pci_dev_data(). The entire body of these functions is #ifdef`ed around CONFIG_PCI_IOV and they cannot be used in any other context, so make them only available when CONFIG_PCI_IOV is selected, and rename them to reflect their actual usage rather than having them masquerade as generic code.
