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. v9: * improve some variable initiation * fix some variable names for consistency * rebase on the latest code v8: * fix some variable names for consistency * clean codes v7: * fix compile issues * add argument *dev in vhost_free_async_mem() for ring type decision v6: * fix some typos in commit log * improve index usage * remove shadow_ring_store() * add store_dma_desc_info_split() store_dma_desc_info_packed() * remove some checks in vhost_free_async_mem() * change index calculation since the size isn't necessarily a power of 2 * move error handling in a dedicated function * clean codes 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/vhost/rte_vhost_async.h | 1 + lib/vhost/vhost.c | 79 +++- lib/vhost/vhost.h | 15 +- lib/vhost/virtio_net.c | 598 +++++++++++++++++++++---- 5 files changed, 587 insertions(+), 110 deletions(-) -- 2.29.2
