NAME¶

libnvmf_context_set_io_queues - Set I/O queue topology for context

SYNOPSIS¶

int libnvmf_context_set_io_queues (struct libnvmf_context *fctx , int nr_io_queues , int nr_write_queues , int nr_poll_queues , int queue_size , bool disable_sqflow );

ARGUMENTS¶

fctx

Fabrics context

nr_io_queues

Number of I/O queues

nr_write_queues

Number of write-only queues

nr_poll_queues

Number of polling queues

queue_size

Number of entries per I/O queue (SQSIZE in Connect command)

disable_sqflow

Disable SQ flow control negotiation

DESCRIPTION¶

Convenience setter for the five parameters that together define the I/O queue structure used when establishing a controller connection. All five feed directly into the Connect command at queue creation time. nr_write_queues and nr_poll_queues are additive: total I/O queues is nr_io_queues + nr_write_queues + nr_poll_queues.

Individual libnvmf_context_set_nr_io_queues, _set_nr_write_queues, _set_nr_poll_queues, _set_queue_size, and _set_disable_sqflow accessors are also available when only a subset needs to change.

RETURN¶

0 on success, negative error code otherwise.
