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()
Please squash these new APIs into where they are used.
This split-up just makes review harder for me as
I can't figure out how the new APIs are used.
Ok.
Thanks
vhost_net: rename VHOST_RX_BATCH to VHOST_NET_BATCH
This is ok as a separate patch.
