This API allows a worker thread to walk over a graph and nodes to create, process, enqueue and move streams of objects to the next nodes.
Definition in file rte_graph_worker_common.h.
#define RTE_GRAPH_MODEL_RTC 0 |
Graph worker models Run-To-Completion model. It is the default model.
Definition at line 31 of file rte_graph_worker_common.h.
#define RTE_GRAPH_MODEL_MCORE_DISPATCH 1 |
Dispatch model to support cross-core dispatching within core affinity.
Definition at line 32 of file rte_graph_worker_common.h.
#define RTE_GRAPH_MODEL_DEFAULT RTE_GRAPH_MODEL_RTC |
Default graph model.

inlinestatic |
Enqueue the objs to next node for further processing and set the next node to pending state in the circular buffer.
graph | Graph pointer returned from rte_graph_lookup(). |
node | Current node pointer. |
next | Relative next node index to enqueue objs. |
objs | Objs to enqueue. |
nb_objs | Number of objs to enqueue. |
Definition at line 289 of file rte_graph_worker_common.h.
|
inlinestatic |
Enqueue only one obj to next node for further processing and set the next node to pending state in the circular buffer.
graph | Graph pointer returned from rte_graph_lookup(). |
node | Current node pointer. |
next | Relative next node index to enqueue objs. |
obj | Obj to enqueue. |
Definition at line 315 of file rte_graph_worker_common.h.
|
inlinestatic |
Enqueue only two objs to next node for further processing and set the next node to pending state in the circular buffer. Same as rte_node_enqueue_x1 but enqueue two objs.
graph | Graph pointer returned from rte_graph_lookup(). |
node | Current node pointer. |
next | Relative next node index to enqueue objs. |
obj0 | Obj to enqueue. |
obj1 | Obj to enqueue. |

inlinestatic |
Enqueue only four objs to next node for further processing and set the next node to pending state in the circular buffer. Same as rte_node_enqueue_x1 but enqueue four objs.
graph | Graph pointer returned from rte_graph_lookup(). |
node | Current node pointer. |
next | Relative next node index to enqueue objs. |
obj0 | 1st obj to enqueue. |

Definition at line 378 of file rte_graph_worker_common.h.
|
inlinestatic |
Enqueue objs to multiple next nodes for further processing and set the next nodes to pending state in the circular buffer. objs[i] will be enqueued to nexts[i].
graph | Graph pointer returned from rte_graph_lookup(). |
node | Current node pointer. |
nexts | List of relative next node indices to enqueue objs. |
objs | List of objs to enqueue. |
nb_objs | Number of objs to enqueue. |
Definition at line 411 of file rte_graph_worker_common.h.
|
inlinestatic |
Get the stream of next node to enqueue the objs. Once done with the updating the objs, needs to call rte_node_next_stream_put to put the next node to pending state.
graph | Graph pointer returned from rte_graph_lookup(). |
node | Current node pointer. |
next | Relative next node index to get stream. |
nb_objs | Requested free size of the next stream. |
Definition at line 440 of file rte_graph_worker_common.h.
|
inlinestatic |
Put the next stream to pending state in the circular buffer for further processing. Should be invoked after rte_node_next_stream_get().
graph | Graph pointer returned from rte_graph_lookup(). |
node | Current node pointer. |
next | Relative next node index.. |
idx | Number of objs updated in the stream after getting the stream using rte_node_next_stream_get. |
Definition at line 470 of file rte_graph_worker_common.h.
|
inlinestatic |
Home run scenario, Enqueue all the objs of current node to next node in optimized way by swapping the streams of both nodes. Performs good when next node is already not in pending state. If next node is already in pending state then normal enqueue will be used.
graph | Graph pointer returned from rte_graph_lookup(). |
src | Current node pointer. |
next | Relative next node index. |

bool rte_graph_model_is_valid | ( | uint8_t | model | ) |
Test the validity of model.
model | Model to check. |
int rte_graph_worker_model_set | ( | uint8_t | model | ) |
model | Name of the graph worker model. |
uint8_t rte_graph_worker_model_get | ( | struct rte_graph * | graph | ) |
Get the graph worker model
graph | Graph pointer. |
|
static |
Get the graph worker model without check
graph | Graph pointer. |
