Are you thinking the helper function would do stop + reconfig with additional port + start + setup port, or just setup the port with an ID the app supplies (only when a port is required, of course)? The second one could be done with little additional code -- the app just needs to check if an additional port is needed when configuring the eventdev, and another helper function could take a list of pairs and return true if any don't have an inbuilt port. > > I am in favor adding more logic in helper function(I believe, first one ) so that it will help > application reuse the helper functions for the normal case. > Hi Jerin, My understanding of the discussion above is that the simple API adapter creation API is int rte_event_eth_rx_adapter_create(id, eventdev_id) And the raw API is typedef int (*rx_adapter_conf_cb) (id, eventdev_id, struct rte_event_eth_rx_adapter_conf *conf, void *arg); struct rte_event_eth_rx_adapter_conf { uint8_t rx_event_port_id; uint32_t max_nb_rx; }; int rte_event_eth_rx_adapter_create_ext(id, eventdev_id, conf_cb, conf_arg) The conf_cb is invoked if the rte_event_eth_rx_adapter_conf struct needs to be filled out. the _create_ext() API is used internally by rte_event_eth_rx_adapter_create() Does that look OK to you ?
