Subject: [PATCH iproute2-next 8/9] rdma: Add QP resource tracking information
From: Leon Romanovsky <leonro@...lanox.com>
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
DEV/PORT LQPN TYPE STATE PID COMM
mlx5_4/- 8 UD RESET 0 [ipoib-verbs]
mlx5_4/1 7 UD RTS 0 [mlx5-gsi]
mlx5_4/1 1 GSI RTS 0 [rdma-mad]
mlx5_4/1 0 SMI RTS 0 [rdma-mad]
$ rdma res show qp link mlx5_4/
DEV/PORT LQPN TYPE STATE PID COMM
mlx5_4/- 8 UD RESET 0 [ipoib-verbs]
mlx5_4/1 7 UD RTS 0 [mlx5-gsi]
mlx5_4/1 1 GSI RTS 0 [rdma-mad]
mlx5_4/1 0 SMI RTS 0 [rdma-mad]
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
DEV/PORT LQPN TYPE STATE PID COMM
mlx5_4/1 7 UD RTS 0 [mlx5-gsi]
mlx5_4/1 1 GSI RTS 0 [rdma-mad]
mlx5_4/1 0 SMI RTS 0 [rdma-mad]
4. Get QPs which have not assigned port yet:
$ rdma res show qp link mlx5_4/-
DEV/PORT LQPN TYPE STATE PID COMM
mlx5_4/- 8 UD RESET 0 [ipoib-verbs]
5. Detailed view:
$ rdma res show qp link mlx5_4/- -d
DEV/PORT LQPN RQPN TYPE STATE PID COMM SQ-PSN RQ-PSN PATH-MIG
mlx5_4/- 8 --- UD RESET 0 [ipoib-verbs] 0 --- ---
6. Limit to specific columns (dev/port is always available):
$ rdma res show qp link mlx5_4/1 display pid,lqpn,comm
DEV/PORT LQPN PID COMM
mlx5_4/1 7 0 [mlx5-gsi]
mlx5_4/1 1 0 [rdma-mad]
mlx5_4/1 0 0 [rdma-mad]
7. Detailed view (no change, due to "display" option):
$ rdma res show qp link mlx5_4/1 display pid,lqpn,comm -d
DEV/PORT LQPN PID COMM
mlx5_4/1 7 0 [mlx5-gsi]
mlx5_4/1 1 0 [rdma-mad]
mlx5_4/1 0 0 [rdma-mad]
8. Limit to specific Local QPNs:
$ rdma res show qp link mlx5_4/1 display pid,lqpn,comm lqpn 0-6
DEV/PORT LQPN PID COMM
mlx5_4/1 1 0 [rdma-mad]
mlx5_4/1 0 0 [rdma-mad]
