Hi all: This series tries to implement rx batching for vhost-net. This is done by batching the dequeuing from skb_array which was exported by underlayer socket and pass the sbk back through msg_control to finish userspace copying.
Tests shows at most 19% improvment on rx pps. Please review. Thanks Jason Wang (8): ptr_ring: introduce batch dequeuing skb_array: introduce batch dequeuing tun: export skb_array tap: export skb_array tun: support receiving skb through msg_control tap: support receiving skb from msg_control vhost_net: try batch dequing from skb array vhost_net: use lockless peeking for skb array during busy polling drivers/net/tap.c | 25 ++++++++++++++--- drivers/net/tun.c | 31 +++++++++++++++------ drivers/vhost/net.c | 71 +++++++++++++++++++++++++++++++++++++++++++---- include/linux/if_tap.h | 5 ++++ include/linux/if_tun.h | 5 ++++ include/linux/ptr_ring.h | 65 +++++++++++++++++++++++++++++++++++++++++++ include/linux/skb_array.h | 25 +++++++++++++++++ 7 files changed, 209 insertions(+), 18 deletions(-) -- 2.7.4
