In order to make async vhost compatible with virtio 1.1 spec this patch set cleans async split ring codes and enables packed ring in async vhost data path. Batch datapath is also enabled in async vhost packed ring. v5: * clean some codes for packed ring datapath * fix an index error in shadow_ring_store() v4: * change the patch structure * clean code for async split ring * reuse some code from split ring * change the error handler for DMA-copy packet * add check for malloc * remove useless code * add doc update v3: * fix error handler for DMA-copy packet v2: * fix wrong buffer index in rte_vhost_poll_enqueue_completed() * add async_buffers_packed memory free in vhost_free_async_mem() Cheng Jiang (4): vhost: abstract and reorganize async split ring code vhost: add support for packed ring in async vhost vhost: add batch datapath for async vhost packed ring doc: add release note for vhost async packed ring doc/guides/rel_notes/release_21_05.rst | 4 + lib/librte_vhost/rte_vhost_async.h | 1 + lib/librte_vhost/vhost.c | 27 +- lib/librte_vhost/vhost.h | 7 +- lib/librte_vhost/virtio_net.c | 613 +++++++++++++++++++++---- 5 files changed, 567 insertions(+), 85 deletions(-) -- 2.29.2
