(Jerin Jacob)\n\n* Fix meson build. (Jerin Jacob)\n\n* Replace calls to pthread_* with rte_ctrl_thread_create().\n (Jerin Jacob)\n\n* Move adapter test code to separate patch. (Jerin Jacob)\n\nNote: I haven't removed the note about devices created\nrte_event_eth_rx_adapter_create, will fix in a separate patch.\n\nNikhil Rao (5):\n eventdev: standardize Rx adapter internal function names\n eventdev: improve err handling for Rx adapter queue add/del\n eventdev: move Rx adapter eth Rx to separate function\n eventdev: add interrupt driven queues to Rx adapter\n eventdev: add Rx adapter tests for interrupt driven queues\n\n config/rte_config.h | 1 +\n lib/librte_eventdev/rte_event_eth_rx_adapter.h | 5 +-\n lib/librte_eventdev/rte_event_eth_rx_adapter.c | 1527 +++++++++++++++++---\n test/test/test_event_eth_rx_adapter.c | 261 +++-\n .../prog_guide/event_ethernet_rx_adapter.rst | 24 +\n config/common_base | 1 +\n lib/librte_eventdev/Makefile | 9 +-\n 7 files changed, 1589 insertions(+), 239 deletions(-)" }
