Subject: [PATCH rfc 0/3] virtio-net: add tx-hash, rx-tstamp and tx-tstamp
Date: Mon, 28 Dec 2020 11:22:30 -0500 [thread overview]
Message-ID: <20201228162233.2032571-1-willemdebruijn.kernel@gmail.com> (raw)
From: Willem de Bruijn <willemb@google.com>
RFC for three new features to the virtio network device:
1. pass tx flow hash and state to host, for routing + telemetry
2. pass rx tstamp to guest, for better RTT estimation
3. pass tx tstamp to host, for accurate pacing
All three would introduce an extension to the virtio spec.
I assume this would require opening three ballots against v1.2 at
https://www.oasis-open.org/committees/ballots.php?wg_abbrev=virtio
This RFC is to informally discuss the proposals first.
The patchset is against v5.10. Evaluation additionally requires
changes to qemu and at least one back-end. I implemented preliminary
support in Linux vhost-net. Both patches available through github at
https://github.com/wdebruij/linux/tree/virtio-net-txhash-1
https://github.com/wdebruij/qemu/tree/virtio-net-txhash-1
Willem de Bruijn (3):
virtio-net: support transmit hash report
virtio-net: support receive timestamp
virtio-net: support transmit timestamp
