Introduce a new netlink command to allow rdma event monitoring. The rdma events supported now are IB device registration/unregistration and net device attachment/detachment. Example output of rdma monitor and the commands which trigger the events: $ rdma monitor $ rmmod mlx5_ib [UNREGISTER] dev 1 rocep8s0f1 [UNREGISTER] dev 0 rocep8s0f0 $ modprobe mlx5_ib [REGISTER] dev 2 mlx5_0 [NETDEV_ATTACH] dev 2 mlx5_0 port 1 netdev 4 eth2 [REGISTER] dev 3 mlx5_1 [NETDEV_ATTACH] dev 3 mlx5_1 port 1 netdev 5 eth3 $ devlink dev eswitch set pci/0000:08:00.0 mode switchdev [UNREGISTER] dev 2 rocep8s0f0 [REGISTER] dev 4 mlx5_0 [NETDEV_ATTACH] dev 4 mlx5_0 port 30 netdev 4 eth2 $ echo 4 > /sys/class/net/eth2/device/sriov_numvfs [NETDEV_ATTACH] dev 4 rdmap8s0f0 port 2 netdev 7 eth4 [NETDEV_ATTACH] dev 4 rdmap8s0f0 port 3 netdev 8 eth5 [NETDEV_ATTACH] dev 4 rdmap8s0f0 port 4 netdev 9 eth6 [NETDEV_ATTACH] dev 4 rdmap8s0f0 port 5 netdev 10 eth7 [REGISTER] dev 5 mlx5_0 [NETDEV_ATTACH] dev 5 mlx5_0 port 1 netdev 11 eth8 [REGISTER] dev 6 mlx5_0 [NETDEV_ATTACH] dev 6 mlx5_0 port 1 netdev 12 eth9 [REGISTER] dev 7 mlx5_0 [NETDEV_ATTACH] dev 7 mlx5_0 port 1 netdev 13 eth10 [REGISTER] dev 8 mlx5_0 [NETDEV_ATTACH] dev 8 mlx5_0 port 1 netdev 14 eth11 $ echo 0 > /sys/class/net/eth2/device/sriov_numvfs [UNREGISTER] dev 5 rocep8s0f0v0 [UNREGISTER] dev 6 rocep8s0f0v1 [UNREGISTER] dev 7 rocep8s0f0v2 [UNREGISTER] dev 8 rocep8s0f0v3 [NETDEV_DETACH] dev 4 rdmap8s0f0 port 2 [NETDEV_DETACH] dev 4 rdmap8s0f0 port 3 [NETDEV_DETACH] dev 4 rdmap8s0f0 port 4 [NETDEV_DETACH] dev 4 rdmap8s0f0 port 5 Signed-off-by: Chiara Meiohas <cmeiohas@nvidia.com> Signed-off-by: Michael Guralnik <michaelgur@nvidia.com> Link: https://patch.msgid.link/20240909173025.30422-7-michaelgur@nvidia.com Signed-off-by: Leon Romanovsky <leon@kernel.org> |
