All descriptors\nare compacted into one single ring when packed ring format is on. It is\nstraight forward that ring operations can be accelerated by utilizing\nSIMD instructions. \n\nThis patch set will introduce vectorized data path in vhost library. If\nvectorized option is on, operations like descs check, descs writeback,\naddress translation will be accelerated by SIMD instructions. Vhost\napplication can choose whether using vectorized acceleration, it is \nlike external buffer and zero copy features. \n\nIf platform or ring format not support vectorized function, vhost will\nfallback to use default batch function. There will be no impact in current\ndata path.\n\nMarvin Liu (5):\n vhost: add vectorized data path\n vhost: reuse packed ring functions\n vhost: prepare memory regions addresses\n vhost: add packed ring vectorized dequeue\n vhost: add packed ring vectorized enqueue\n\n doc/guides/nics/vhost.rst | 5 +\n doc/guides/prog_guide/vhost_lib.rst | 12 ++\n drivers/net/vhost/rte_eth_vhost.c | 17 +-\n lib/librte_vhost/Makefile | 13 ++\n lib/librte_vhost/meson.build | 16 ++\n lib/librte_vhost/rte_vhost.h | 1 +\n lib/librte_vhost/socket.c | 5 +\n lib/librte_vhost/vhost.c | 11 ++\n lib/librte_vhost/vhost.h | 235 ++++++++++++++++++++++\n lib/librte_vhost/vhost_user.c | 11 ++\n lib/librte_vhost/vhost_vec_avx.c | 292 ++++++++++++++++++++++++++++\n lib/librte_vhost/virtio_net.c | 257 ++++--------------------\n 12 files changed, 659 insertions(+), 216 deletions(-)\n create mode 100644 lib/librte_vhost/vhost_vec_avx.c" }
