Hi all, This series implements VIRTIO_F_IN_ORDER support for vhost-net. This feature is designed to improve the performance of the virtio ring by optimizing descriptor processing. Benchmarks show a notable improvement. Please see patch 3 for details. Changes since V1: - add a new patch to fail early when vhost_add_used() fails - drop unused parameters of vhost_add_used_ooo() - conisty nheads for vhost_add_used_in_order() - typo fixes and other tweaks Thanks Jason Wang (3): vhost: fail early when __vhost_add_used() fails vhost: basic in order support vhost_net: basic in_order support drivers/vhost/net.c | 88 +++++++++++++++++++++--------- drivers/vhost/vhost.c | 123 ++++++++++++++++++++++++++++++++++-------- drivers/vhost/vhost.h | 8 ++- 3 files changed, 171 insertions(+), 48 deletions(-) -- 2.39.5
