Users need pass only as many fields as necessary; vendor, device,
subvendor, and subdevice fields default to PCI_ANY_ID (FFFFFFFF),
class and classmask fields default to 0, and driver_data defaults to
-0UL. Device drivers must call
- pci_dynids_set_use_driver_data(pci_driver *, 1)
-in order for the driver_data field to get passed to the driver.
-Otherwise, only a 0 is passed in that field.
+0UL. Device drivers must initialize use_driver_data in the dynids struct
+in their pci_driver struct prior to calling pci_register_driver in order
+for the driver_data field to get passed to the driver. Otherwise, only a
+0 is passed in that field.
When the driver exits, it just calls pci_unregister_driver() and the PCI layer
automatically calls the remove hook for all devices handled by the driver.
Searching by vendor and device ID:
struct pci_dev *dev = NULL;
- while (dev = pci_find_device(VENDOR_ID, DEVICE_ID, dev))
+ while (dev = pci_get_device(VENDOR_ID, DEVICE_ID, dev))
configure_device(dev);
Searching by class ID (iterate in a similar way):
- pci_find_class(CLASS_ID, dev)
+ pci_get_class(CLASS_ID, dev)
Searching by both vendor/device and subsystem vendor/device ID:
- pci_find_subsys(VENDOR_ID, DEVICE_ID, SUBSYS_VENDOR_ID, SUBSYS_DEVICE_ID, dev).
+ pci_get_subsys(VENDOR_ID, DEVICE_ID, SUBSYS_VENDOR_ID, SUBSYS_DEVICE_ID, dev).
You can use the constant PCI_ANY_ID as a wildcard replacement for
VENDOR_ID or DEVICE_ID. This allows searching for any device from a
specific vendor, for example.
-Note that these functions are not hotplug-safe. Their hotplug-safe
-replacements are pci_get_device(), pci_get_class() and pci_get_subsys().
-They increment the reference count on the pci_dev that they return.
-You must eventually (possibly at module unload) decrement the reference
-count on these devices by calling pci_dev_put().
