Field Documentation

type

odp_queue_type_t odp_queue_param_t::type

Queue type.

Valid values for other parameters in this structure depend on the queue type. The default value is ODP_QUEUE_TYPE_PLAIN.

Examples

ipsec_api/odp_ipsec.c, ipsec_crypto/odp_ipsec.c, odp_bench_pktio_sp.c, odp_bench_timer.c, odp_classifier.c, odp_cpu_bench.c, odp_crypto.c, odp_debug.c, odp_dma_perf.c, odp_dmafwd.c, odp_ipfragreass.c, odp_ipsec.c, odp_ipsecfwd.c, odp_l2fwd.c, odp_pktio_ordered.c, odp_queue_perf.c, odp_sched_latency.c, odp_sched_perf.c, odp_sched_pktio.c, odp_simple_pipeline.c, odp_stress.c, odp_timer_accuracy.c, odp_timer_perf.c, and odp_timer_simple.c.

Definition at line 229 of file api/spec/queue_types.h.

enq_mode

odp_queue_op_mode_t odp_queue_param_t::enq_mode

Enqueue mode.

Default value for both queue types is ODP_QUEUE_OP_MT. Application may enable performance optimizations by defining MT_UNSAFE or DISABLED modes when applicable.

Examples

odp_ipfragreass.c, odp_queue_perf.c, and odp_simple_pipeline.c.

Definition at line 236 of file api/spec/queue_types.h.

deq_mode

odp_queue_op_mode_t odp_queue_param_t::deq_mode

Dequeue mode.

For PLAIN queues, the default value is ODP_QUEUE_OP_MT. Application may enable performance optimizations by defining MT_UNSAFE or DISABLED modes when applicable. However, when a plain queue is input to the implementation (e.g. a queue for packet output), the parameter is ignored in queue creation and the value is ODP_QUEUE_OP_DISABLED.

For SCHED queues, the parameter is ignored in queue creation and the value is ODP_QUEUE_OP_DISABLED.

Examples

odp_ipfragreass.c, odp_queue_perf.c, and odp_simple_pipeline.c.

Definition at line 249 of file api/spec/queue_types.h.

sched

odp_schedule_param_t odp_queue_param_t::sched

Scheduler parameters.

These parameters are considered only when queue type is ODP_QUEUE_TYPE_SCHED.

Examples

ipsec_api/odp_ipsec.c, ipsec_crypto/odp_ipsec.c, odp_bench_timer.c, odp_classifier.c, odp_cpu_bench.c, odp_crypto.c, odp_debug.c, odp_dma_perf.c, odp_dmafwd.c, odp_ipsec.c, odp_ipsecfwd.c, odp_l2fwd.c, odp_packet_dump.c, odp_packet_gen.c, odp_ping.c, odp_pktio.c, odp_pktio_ordered.c, odp_sched_latency.c, odp_sched_perf.c, odp_sched_pktio.c, odp_stress.c, odp_timer_accuracy.c, odp_timer_perf.c, and odp_timer_simple.c.

Definition at line 255 of file api/spec/queue_types.h.

order

odp_queue_order_t odp_queue_param_t::order

Original event order maintenance.

Keep or ignore the original event order of a source queue. The default value is ODP_QUEUE_ORDER_KEEP.

Definition at line 261 of file api/spec/queue_types.h.

nonblocking

odp_nonblocking_t odp_queue_param_t::nonblocking

Non-blocking level.

Queue implementation must guarantee at least this level of block freedom for queue enqueue and dequeue/schedule operations. The default value is ODP_BLOCKING.

Examples

odp_queue_perf.c.

Definition at line 268 of file api/spec/queue_types.h.

context

void* odp_queue_param_t::context

Queue context pointer.

User defined context pointer associated with the queue. The same pointer can be accessed with odp_queue_context() and odp_queue_context_set() calls. The implementation may read the pointer for prefetching the context data. Default value of the pointer is NULL.

Examples

odp_pktio_ordered.c.

Definition at line 277 of file api/spec/queue_types.h.

context_len

uint32_t odp_queue_param_t::context_len

Queue context data length.

User defined context data length in bytes for prefetching. The implementation may use this value as a hint for the number of context data bytes to prefetch. Default value is zero (no hint).

Examples

odp_pktio_ordered.c.

Definition at line 284 of file api/spec/queue_types.h.

size

uint32_t odp_queue_param_t::size

Queue size.

The queue must be able to store at minimum this many events simultaneously. The value must not exceed 'max_size' queue capability. The value of zero means implementation specific default size. The default value is 0.

Examples

odp_cpu_bench.c, odp_pktio_ordered.c, odp_queue_perf.c, odp_sched_perf.c, odp_sched_pktio.c, and odp_simple_pipeline.c.
