In 20.08, explicit deprecation warnings will be displayed when running scripts with Python 2. + +* eventdev: Three public data structures will be updated in 20.11; + ``rte_event_dev_info``, ``rte_event_dev_config``, and + ``rte_event_port_conf``. + Two new members will be added to the ``rte_event_dev_info`` struct. + The first, max_event_port_links, will be a uint8_t, and represents the + maximum number of queues that can be linked to a single event port by + this device. The second, max_single_link_event_port_queue_pairs, will be a + uint8_t, and represents the maximum number of event ports and queues that + are optimized for (and only capable of) single-link configurations + supported by this device. These ports and queues are not accounted for in + max_event_ports or max_event_queues. + One new member will be added to the ``rte_event_dev_config`` struct. The + nb_single_link_event_port_queues member will be a uint8_t, and will + represent the number of event ports and queues that will be singly-linked + to each other. These are a subset of the overall event ports and queues. + This value cannot exceed nb_event_ports or nb_event_queues. If the + device has ports and queues that are optimized for single-link usage, this + field is a hint for how many to allocate; otherwise, regular event ports and + queues can be used. + Finally, the ``rte_event_port_conf`` struct will be + modified as follows. The uint8_t implicit_release_disabled field + will be replaced by a uint32_t event_port_cfg field. The new field will + initially have two bits assigned. RTE_EVENT_PORT_CFG_DISABLE_IMPL_REL + will have the same meaning as implicit_release_disabled. The second bit, + RTE_EVENT_PORT_CFG_SINGLE_LINK will be set if the event port links only + to a single event queue. + -- 1.7.10
