Subject: [dpdk-dev] [RFC 00/14] vhost: clean-up and simplify async implementation
Date: Thu,  7 Oct 2021 23:59:59 +0200
Message-ID: <20211007220013.355530-1-maxime.coquelin@redhat.com> (raw)

This series aims at cleaning and simplifying the async
enqueue path. 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.

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
