Function Documentation

TAILQ_HEAD	(	vdev_driver_list	,
		rte_vdev_driver
	)

Double linked list of virtual device drivers.

void rte_vdev_register

(

struct rte_vdev_driver *

driver

)

Register a virtual device driver.

Parameters

driver

A pointer to a rte_vdev_driver structure describing the driver to be registered.

void rte_vdev_unregister

(

struct rte_vdev_driver *

driver

)

Unregister a virtual device driver.

Parameters

driver

A pointer to a rte_vdev_driver structure describing the driver to be unregistered.

int rte_vdev_add_custom_scan	(	rte_vdev_scan_callback	callback,
		void *	user_arg
	)

Add a callback to be called on vdev scan before reading the devargs list.

This function cannot be called in a scan callback because of deadlock.

Parameters

callback	The function to be called which can update the devargs list.
user_arg	An opaque pointer passed to callback.

Returns

0 on success, negative on error

int rte_vdev_remove_custom_scan	(	rte_vdev_scan_callback	callback,
		void *	user_arg
	)

Remove a registered scan callback.

This function cannot be called in a scan callback because of deadlock.

Parameters

callback	The registered function to be removed.
user_arg	The associated opaque pointer or (void*)-1 for any.

Returns

0 on success

int rte_vdev_init	(	const char *	name,
		const char *	args
	)

Initialize a driver specified by name.

Parameters

name	The pointer to a driver name to be initialized.
args	The pointer to arguments used by driver initialization.

Returns

0 on success, negative on error

int rte_vdev_uninit

(

const char *

name

)

Uninitalize a driver specified by name.

Parameters

name	The pointer to a driver name to be uninitialized.

Returns

0 on success, negative on error
