Field Documentation

int( * ib_device_operations::create_cq)(struct ib_device *ibdev, struct ib_completion_queue *cq)

Create completion queue.

Parameters:

	ibdev	Infiniband device
	cq	Completion queue

Return values:

rc

Return status code

Referenced by ib_create_cq().

void( * ib_device_operations::destroy_cq)(struct ib_device *ibdev, struct ib_completion_queue *cq)

Destroy completion queue.

Parameters:

	ibdev	Infiniband device
	cq	Completion queue

Referenced by ib_create_cq(), and ib_destroy_cq().

int( * ib_device_operations::create_qp)(struct ib_device *ibdev, struct ib_queue_pair *qp)

Create queue pair.

Parameters:

	ibdev	Infiniband device
	qp	Queue pair

Return values:

rc

Return status code

Referenced by ib_create_qp().

int( * ib_device_operations::modify_qp)(struct ib_device *ibdev, struct ib_queue_pair *qp)

Modify queue pair.

Parameters:

	ibdev	Infiniband device
	qp	Queue pair

Return values:

rc

Return status code

Referenced by ib_modify_qp().

void( * ib_device_operations::destroy_qp)(struct ib_device *ibdev, struct ib_queue_pair *qp)

Destroy queue pair.

Parameters:

	ibdev	Infiniband device
	qp	Queue pair

Referenced by ib_create_qp(), and ib_destroy_qp().

int( * ib_device_operations::post_send)(struct ib_device *ibdev, struct ib_queue_pair *qp, struct ib_address_vector *av, struct io_buffer *iobuf)

Post send work queue entry.

Parameters:

	ibdev	Infiniband device
	qp	Queue pair
	av	Address vector
	iobuf	I/O buffer

Return values:

rc

Return status code

If this method returns success, the I/O buffer remains owned by the queue pair. If this method returns failure, the I/O buffer is immediately released; the failure is interpreted as "failure to enqueue buffer".

Referenced by ib_post_send().

int( * ib_device_operations::post_recv)(struct ib_device *ibdev, struct ib_queue_pair *qp, struct io_buffer *iobuf)

Post receive work queue entry.

Parameters:

	ibdev	Infiniband device
	qp	Queue pair
	iobuf	I/O buffer

Return values:

rc

Return status code

If this method returns success, the I/O buffer remains owned by the queue pair. If this method returns failure, the I/O buffer is immediately released; the failure is interpreted as "failure to enqueue buffer".

Referenced by ib_post_recv().

void( * ib_device_operations::poll_cq)(struct ib_device *ibdev, struct ib_completion_queue *cq)

Poll completion queue.

Parameters:

	ibdev	Infiniband device
	cq	Completion queue

The relevant completion handler (specified at completion queue creation time) takes ownership of the I/O buffer.

Referenced by ib_poll_cq().

void( * ib_device_operations::poll_eq)(struct ib_device *ibdev)
