PCI_CREATE_SLOT(9) Hardware Interfaces PCI_CREATE_SLOT(9)NAME
pci_create_slot - create or increment refcount for physical PCI slot
struct pci_slot * pci_create_slot(struct pci_bus * parent, int slot_nr, const char * name, struct hotplug_slot * hotplug);
struct pci_bus of parent bridge
PCI_SLOT(pci_dev->devfn) or -1 for placeholder
user visible string presented in /sys/bus/pci/slots/<name>
set if caller is hotplug driver, NULL otherwise
PCI slots have first class attributes such as address, speed, width, and a struct pci_slot is used to manage them. This interface will
either return a new struct pci_slot to the caller, or if the pci_slot already exists, its refcount will be incremented.
Slots are uniquely identified by a pci_bus, slot_nr tuple.
There are known platforms with broken firmware that assign the same name to multiple slots. Workaround these broken platforms by renaming
the slots on behalf of the caller. If firmware assigns name N to
The first slot is assigned N The second slot is assigned N-1 The third slot is assigned N-2 etc.
In most cases, pci_bus, slot_nr will be sufficient to uniquely identify a slot. There is one notable exception - pSeries (rpaphp), where
the slot_nr cannot be determined until a device is actually inserted into the slot. In this scenario, the caller may pass -1 for slot_nr.
The following semantics are imposed when the caller passes slot_nr == -1. First, we no longer check for an existing struct pci_slot, as
there may be many slots with slot_nr of -1. The other change in semantics is user-visible, which is the 'address' parameter presented in
CONSIST SOLELY OF A DDDD
bb tuple, where dddd is the PCI domain of the struct pci_bus and bb is the bus number. In other words, the devfn of the 'placeholder' slot
will not be displayed.
