int ib_register_client ( struct ib_client client)

ib_register_client - Register an IB client :Client to register

Upper level users of the IB drivers can use ib_register_client() to register callbacks for IB device addition and removal. When an IB device is added, each registered client's add method will be called (in the order the clients were registered), and when a device is removed, each client's remove method will be called (in the reverse order that clients were registered). In addition, when ib_register_client() is called, the client will receive an add callback for all devices already registered.

Definition at line 380 of file device.c.

int ib_register_device ( struct ib_device device,
int(*)(struct ib_device *, u8, struct kobject *)  port_callback 

ib_register_device - Register an IB device with IB core :Device to register

Low-level drivers use ib_register_device() to register their devices with the IB core. All registered clients will receive a callback for each device that is added. must be allocated with ib_alloc_device().

Definition at line 273 of file device.c.

int ib_register_event_handler ( struct ib_event_handler event_handler)

ib_register_event_handler - Register an IB event handler :Handler to register

ib_register_event_handler() registers an event handler that will be called back when asynchronous IB events occur (as defined in chapter 11 of the InfiniBand Architecture Specification). This callback may occur in interrupt context.

Definition at line 496 of file device.c.

void ib_set_client_data ( struct ib_device device,
struct ib_client client,
void data 

ib_set_client_data - Set IB client context :Device to set context for :Client to set context for :Context to set

ib_set_client_data() sets client context that can be retrieved with ib_get_client_data().

Definition at line 466 of file device.c.

void ib_unregister_client ( struct ib_client client)

ib_unregister_client - Unregister an IB client :Client to unregister

Upper level users use ib_unregister_client() to remove their client registration. When ib_unregister_client() is called, the client will receive a remove callback for each IB device still registered.

Definition at line 405 of file device.c.

void ib_unregister_device ( struct ib_device device)
