2024-10-31virtio: introduce the consistent-qp featureMohammed Hawari8-15/+29
In certain usecases related to Linux legacy pinning of flows on queue pairs, it is desirable that, for a given index, the rx and tx virtio queue be handled by the same worker. This change introduces a flag for virtio and tap interfaces that allow such a mapping. Example with two workers rxq 0 and txq 0 on worker 0 rxq 1 and txq 1 on worker 1 txq 2 on main thread Change-Id: I1b74a4788843fd1d0e8dcb4e9da30e609e088fe3 Signed-off-by: Mohammed Hawari <mohammed@hawari.fr> Type: improvement
2024-09-06linux-cp: auto select tap id when creating lcp pairStanislav Zaikin2-2/+4
Now when lcp pair is created, tap instance is based on hw_id. But tap interface with such instance can already exist. Introduce an offset and auto-selection based on it. Type: fix Signed-off-by: Stanislav Zaikin <stanislav.zaikin@46labs.com> Change-Id: I9db39106b0b0d5bf95c445b03e5b7ff52f946dd2

Add RSS support to make use of multiple queues. With 4 RX queues and RSS enabled ping from host to guest vm ip queue use 192.168.2.3 192.168.2.1 2 '' 192.168.2.10 0 '' 192.168.2.5 1 '' 192.168.2.105 3 With 4 RX queues and RSS disabled, queue 0 is always used for all of the above cases Type: improvement Change-Id: I3ca78fd83fce26cbe8f23fee0a9034cb572bacb7 Signed-off-by: Steven Luong <sluong@cisco.com>
2024-05-23virtio: Add RX queue full statisiticsSteven Luong2-0/+11
In production network, often the host and the vm are managed by different groups. The host statistics may not be readily available to the folks who manage the VM. Having the RX queue full statistics in VPP can inform that there might possibly be drops in the host.
