While investigating vhost-vdpa initialization issue with mlx5 vDPA, we found two issues fixed by following patches.
In this v2, the control queue issue mentioned in v1 is fixed. It turned out to the control queue being enabled only if multiqueue was negotiated. It is fixed by enabling it at device startup, and disabling it at stop time. We still have an issue on one of our setup with mlx5, where the mlx5 device sets VIRTIO_CONFIG_S_FAILED status, it is currently being investigated. Changes in v2: -------------- - Fix cvq enablement - Fix typo in commit message (David) Maxime Coquelin (2): net/virtio: fix vDPA device init advertising control queue net/virtio: fix notification area initialization .../net/virtio/virtio_user/virtio_user_dev.c | 27 +++++++++++++------ 1 file changed, 19 insertions(+), 8 deletions(-) -- 2.44.0
