◆ create_cq

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

Definition at line 262 of file infiniband.h.

Referenced by ib_create_cq().

◆ destroy_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

Definition at line 269 of file infiniband.h.

Referenced by ib_create_cq(), and ib_destroy_cq().

◆ create_qp

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

Definition at line 277 of file infiniband.h.

Referenced by ib_create_qp().

◆ modify_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

Definition at line 285 of file infiniband.h.

Referenced by ib_modify_qp().

◆ destroy_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

Definition at line 292 of file infiniband.h.

Referenced by ib_create_qp(), and ib_destroy_qp().

◆ post_send

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

Post send work queue entry.

Parameters

ibdev	Infiniband device
qp	Queue pair
dest	Destination 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".

◆ post_recv

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".

Parameters
