Subject: [dpdk-dev] [PATCH v1 00/14] vhost: clean-up and simplify async implementation
Date: Mon, 18 Oct 2021 15:02:15 +0200 [thread overview]
Message-ID: <20211018130229.308694-1-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.
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
