Function Documentation

static int __pci_device_probe	(	struct pci_driver *	drv,
		struct pci_dev *	pci_dev
	)			`[static]`

__pci_device_probe() : driver to call to check if it wants the PCI device : PCI device being probed

returns 0 on success, else error. side-effect: pci_dev->driver is set to drv when drv claims pci_dev.

Definition at line 242 of file pci-driver.c.

int __pci_register_driver	(	struct pci_driver *	drv,
		struct module *	owner,
		const char *	mod_name
	)

__pci_register_driver - register a new pci driver : the driver structure to register : owner module of drv : module name string

Adds the driver structure to the list of registered drivers. Returns a negative value on error, otherwise 0. If no error occurred, the driver remains registered even if no device was claimed during registration.

static int pci_bus_match	(	struct device *	dev,
		struct device_driver *	drv
	)			`[static]`

pci_bus_match - Tell if a PCI device structure has a matching PCI device id structure : the PCI device structure to match against : the device driver to search for matching PCI device id structures

Used by a driver to check whether a PCI device present in the system is in its list of supported devices. Returns the matching pci_device_id structure or NULL if there is no match.

struct pci_driver* pci_dev_driver ( const struct pci_dev * dev ) [read]

pci_dev_driver - get the pci_driver of a device : the device to query

Returns the appropriate pci_driver structure or NULL if there is no registered driver for the device.

Definition at line 908 of file pci-driver.c.

struct pci_dev* pci_dev_get ( struct pci_dev * dev ) [read]

pci_dev_get - increments the reference count of the pci device structure : the device being referenced

Each live reference to a device should be refcounted.

Drivers for PCI devices should normally record such references in their probe() methods, when they bind to a device, and release them by calling pci_dev_put(), in their disconnect() methods.

A pointer to the device with the incremented reference counter is returned.

Definition at line 955 of file pci-driver.c.

void pci_dev_put ( struct pci_dev * dev )

pci_dev_put - release a use of the pci device structure : device that's been disconnected

Must be called when a user of a device is finished with it. When the last user of the device calls this function, the memory of the device is freed.

static struct pci_device_id* pci_match_device	(	struct pci_driver *	drv,

	)			`[static, read]`

pci_match_device - Tell if a PCI device structure has a matching PCI device id structure : the PCI driver to match against : the PCI device structure to match against

Used by a driver to check whether a PCI device present in the system is in its list of supported devices. Returns the matching pci_device_id structure or NULL if there is no match.

Definition at line 175 of file pci-driver.c.

struct pci_device_id* pci_match_id	(	const struct pci_device_id *	ids,
		struct pci_dev *	dev
	)			`[read]`

pci_match_id - See if a pci device matches a given pci_id table : array of PCI device id structures to search in : the PCI device structure to match against.

Used by a driver to check whether a PCI device present in the system is in its list of supported devices. Returns the matching pci_device_id structure or NULL if there is no match.

Deprecated, don't use this as it will not catch any dynamic ids that a driver might want to check for.

Definition at line 976 of file pci-driver.c.

void pci_unregister_driver ( struct pci_driver * drv )

pci_unregister_driver - unregister a pci driver : the driver structure to unregister

Deletes the driver structure from the list of registered PCI drivers, gives it a chance to clean up by calling its remove() function for each device it was responsible for, and marks those devices as driverless.
