Detailed Description

RTE Pipeline Input Port Actions

This API provides a common set of actions for pipeline input ports to speed up application development.

Each pipeline input port can be assigned an action handler to be executed on every input packet during the pipeline execution. The pipeline library allows the user to define his own input port actions by providing customized input port action handler. While the user can still follow this process, this API is intended to provide a quicker development alternative for a set of predefined actions.

The typical steps to use this API are:

EXPERIMENTAL: this API may change without prior notice

Function Documentation

◆ rte_port_in_action_profile_create()

__rte_experimental struct rte_port_in_action_profile* rte_port_in_action_profile_create ( uint32_t  socket_id)

Input port action profile create.

Parameters
[in]socket_idCPU socket ID for the internal data structures memory allocation.
Returns
Input port action profile handle on success, NULL otherwise.
Examples:
examples/ip_pipeline/action.c.

◆ rte_port_in_action_profile_free()

__rte_experimental int rte_port_in_action_profile_free ( struct rte_port_in_action_profile *  profile)

Input port action profile free.

Parameters
[in]profileInput port action profile handle (needs to be valid).
Returns
Zero on success, non-zero error code otherwise.
Examples:
examples/ip_pipeline/action.c.

◆ rte_port_in_action_profile_action_register()

__rte_experimental int rte_port_in_action_profile_action_register ( struct rte_port_in_action_profile *  profile,
enum rte_port_in_action_type  type,
void *  action_config 
)

Input port action profile action register.

Parameters
[in]profileInput port action profile handle (needs to be valid and not in frozen state).
[in]typeSpecific input port action to be registered for profile.
[in]action_configConfiguration for the type action. If struct rte_port_in_action_*type*_config is defined, it needs to point to a valid instance of this structure, otherwise it needs to be set to NULL.
Returns
Zero on success, non-zero error code otherwise.
Examples:
examples/ip_pipeline/action.c.

◆ rte_port_in_action_profile_freeze()

__rte_experimental int rte_port_in_action_profile_freeze ( struct rte_port_in_action_profile *  profile)

Input port action profile freeze.

Once this function is called successfully, the given profile enters the frozen state with the following immediate effects: no more actions can be registered for this profile, so the profile can be instantiated to create input port action objects.

Parameters
[in]profileInput port profile action handle (needs to be valid and not in frozen state).
Returns
Zero on success, non-zero error code otherwise.

rte_port_in_action_create()
Examples:
examples/ip_pipeline/action.c.

◆ rte_port_in_action_create()

__rte_experimental struct rte_port_in_action* rte_port_in_action_create ( struct rte_port_in_action_profile *  profile,
uint32_t  socket_id 
)

Input port action create.

Instantiates the given input port action profile to create an input port action object.

Parameters
[in]profileInput port profile action handle (needs to be valid and in frozen state).
[in]socket_idCPU socket ID where the internal data structures required by the new input port action object should be allocated.
Returns
Handle to input port action object on success, NULL on error.
Examples:
examples/ip_pipeline/pipeline.c.

◆ rte_port_in_action_free()

__rte_experimental int rte_port_in_action_free ( struct rte_port_in_action *  action)

Input port action free.

Parameters
[in]actionHandle to input port action object (needs to be valid).
Returns
Zero on success, non-zero error code otherwise.
Examples:
examples/ip_pipeline/pipeline.c.

◆ rte_port_in_action_params_get()

__rte_experimental int rte_port_in_action_params_get ( struct rte_port_in_action *  action,
struct rte_pipeline_port_in_params params 
)

Input port params get.

Parameters
[in]actionHandle to input port action object (needs to be valid).
[in,out]paramsPipeline input port parameters (needs to be pre-allocated).
Returns
Zero on success, non-zero error code otherwise.
Examples:
examples/ip_pipeline/pipeline.c.

◆ rte_port_in_action_apply()

__rte_experimental int rte_port_in_action_apply ( struct rte_port_in_action *  action,
enum rte_port_in_action_type  type,
void *  action_params 
)

Input port action apply.

Parameters
[in]actionHandle to input port action object (needs to be valid).
[in]typeSpecific input port action previously registered for the input port action profile of the action object.
[in]action_paramsParameters for the type action. If struct rte_port_in_action_*type*_params is defined, it needs to point to a valid instance of this structure, otherwise it needs to be set to NULL.
Returns
Zero on success, non-zero error code otherwise.
