I think it makes the code easier to understand, and is necessary before integrating new changes. I may have more reworks to propose in next revisions, but I wanted to share my current status early so that you have time to review/test it. It is only compile-tested, as I don't have HW with IOAT support to test it. Changes in v1: ============== - Fix missing iovec index increment (Jiayu) - Remove unneeded sanity check on IOV iter index (Jiayu) - Fix async->pkts_info allocation check (Jiayu) - Prevent NULL pointer dereference on async metadata cleanup (Jiayu) Maxime Coquelin (14): vhost: move async data in a dedicated structure vhost: hide inflight async structure vhost: simplify async IO vectors vhost: simplify async IO vectors iterators vhost: remove async batch threshold vhost: introduce specific iovec structure vhost: remove useless fields in async iterator struct vhost: improve IO vector logic vhost: remove notion of async descriptor vhost: simplify async enqueue completion vhost: simplify getting the first in-flight index vhost: prepare async for mbuf to desc refactoring vhost: prepare sync for mbuf to desc refactoring vhost: merge sync and async mbuf to desc filling examples/vhost/ioat.c | 30 +- examples/vhost/ioat.h | 2 +- lib/vhost/rte_vhost_async.h | 42 +-- lib/vhost/vhost.c | 130 +++---- lib/vhost/vhost.h | 67 ++-- lib/vhost/vhost_user.c | 4 +- lib/vhost/virtio_net.c | 693 +++++++++++++----------------------- 7 files changed, 376 insertions(+), 592 deletions(-) -- 2.31.1
