Hi:
This series tries to implement basic tx batched processing. This is done by prefetching descriptor indices and update used ring in a batch. This intends to speed up used ring updating and improve the cache utilization. Test shows about ~22% improvement in tx pss.
Please review.
Jason Wang (5): vhost: split out ring head fetching logic vhost: introduce helper to prefetch desc index vhost: introduce vhost_add_used_idx() vhost_net: rename VHOST_RX_BATCH to VHOST_NET_BATCH vhost_net: basic tx virtqueue batched processing
