rdma: Add QP resource tracking information
This patch adds ss-similar interface to view various resource tracked objects. At this stage, only QP is presented. 1. Get all QPs for the specific device: $ rdma res show qp link mlx5_4 link mlx5_4/- lqpn 8 type UD state RESET sq-psn 0 pid 0 comm [ib_ipoib] link mlx5_4/1 lqpn 7 type UD state RTS sq-psn 0 pid 0 comm [ib_core] link mlx5_4/1 lqpn 1 type GSI state RTS sq-psn 0 pid 0 comm [ib_core] link mlx5_4/1 lqpn 0 type SMI state RTS sq-psn 0 pid 0 comm [ib_core] $ rdma res show qp link mlx5_4/ link mlx5_4/- lqpn 8 type UD state RESET sq-psn 0 pid 0 comm [ib_ipoib] link mlx5_4/1 lqpn 7 type UD state RTS sq-psn 0 pid 0 comm [ib_core] link mlx5_4/1 lqpn 1 type GSI state RTS sq-psn 0 pid 0 comm [ib_core] link mlx5_4/1 lqpn 0 type SMI state RTS sq-psn 0 pid 0 comm [ib_core] 2. Provide illegal port number (0 is illegal): $ rdma res show qp link mlx5_4/0 Wrong device name 3. Get QPs of specific port: $ rdma res show qp link mlx5_4/1 link mlx5_4/1 lqpn 7 type UD state RTS sq-psn 0 pid 0 comm [ib_core] link mlx5_4/1 lqpn 1 type GSI state RTS sq-psn 0 pid 0 comm [ib_core] link mlx5_4/1 lqpn 0 type SMI state RTS sq-psn 0 pid 0 comm [ib_core] 4. Get QPs which have not assigned port yet: link mlx5_4/- lqpn 8 type UD state RESET sq-psn 0 pid 0 comm [ib_ipoib] 5. Limit to specific Local QPNs: $ rdma res show qp link mlx5_4/1 lqpn 1-3,7 link mlx5_4/1 lqpn 7 type UD state RTS sq-psn 0 pid 0 comm [ib_core] link mlx5_4/1 lqpn 1 type GSI state RTS sq-psn 0 pid 0 comm [ib_core] link mlx5_4/1 lqpn 0 type SMI state RTS sq-psn 0 pid 0 comm [ib_core] . Filter types (strings): $ rdma res show qp link mlx5_4/1 type UD,gSi link mlx5_4/1 lqpn 7 type UD state RTS sq-psn 0 pid 0 comm [ib_core] link mlx5_4/1 lqpn 1 type GSI state RTS sq-psn 0 pid 0 comm [ib_core] Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>
