Subject: [dpdk-dev] [PATCH v8 00/15] Vhost: add support to packed ring layout
Date: Thu, 5 Jul 2018 23:07:26 +0200 [thread overview]
Message-ID: <20180705210741.17974-1-maxime.coquelin@redhat.com> (raw)
This series is a handover from Jen's "[PATCH v4 00/20]
implement packed virtqueues", which only implements the
vhost side. Virtio PMD implementation will follow in a
next series.
The series applies on top of previous reworks I posted
during this cycle that merges mergeable and non-mergeable
receive paths, and refactors transmit path to re-use
vector buffers.
I haven't run performance tests for now as the Virtio PMD
side isn't ready.
The series has been tested with Tiwei's series implementing
packed ring support to Kernel's virtio-net driver, and
with Wei series implementing the Qemu side.
To test it, I have used testpmd on host side with a vhost
vdev and a tap vdev forwarding to each other. Transferts
of big random files have been done in both ways with
integrity verified.
Tests have been run with Rx mrg ON/OFF and events suppression
ON/OFF.
Tests have also been run with legacy split ring layout to
ensure no regression have been introduced.
Changes since v7:
=================
- Align structs and defines naming with Kernel header (Tiwei)
- Fix event based notifications (Tiwei)
- Fix Clang build issues caused by unused symbols (Tiwei)
Changes since v6:
=================
- Various style cleanups (Tiwei, Jason)
- Simplify event based notification (Jason)
- Build support with future kernels (Tiwei)
- Prevent buffer vectors overflow in map_one_desc (Tiwei)
Changes since v5:
=================
- Remove duplicated VHOST_USER_F_PROTOCOL_FEATURES definition (Tiwei)
- Fix vq_is_ready (Maxime)
- Fix local used index overflow in flush_shadow_used_ring_packed (Tiwei)
- Make desc_is_avail() a bool (Tiwei)
- Improve desc_is_avail() logic (Tiwei)
- Remove split rings addr NULL assignment in the right patch (Tiwei)
- Make buffer id a uint16_t (Tiwei)
