Hi All I'm running tests from https://github.com/linux-rdma/rdma-core/tree/master and got the following errors from all tests.test_mlx5_dc.DCTest tests: build/bin/run_tests.py --dev mlx5_2 --port 1 tests.test_mlx5_dc.DCTest.test_dc_rdma_write E ====================================================================== ERROR: test_dc_rdma_write (tests.test_mlx5_dc.DCTest) ---------------------------------------------------------------------- Traceback (most recent call last): File "/data/rdma-core.master/tests/test_mlx5_dc.py", line 62, in test_dc_rdma_write send_ops_flags=e.IBV_QP_EX_WITH_RDMA_WRITE) File "/data/rdma-core.master/tests/test_mlx5_dc.py", line 53, in create_players self.client.pre_run(self.server.psns, self.server.qps_num) File "/data/rdma-core.master/tests/mlx5_base.py", line 36, in pre_run self.to_rts() File "/data/rdma-core.master/tests/mlx5_base.py", line 31, in to_rts self.dct_qp.to_rtr(attr) File "qp.pyx", line 1113, in pyverbs.qp.QP.to_rtr pyverbs.pyverbs_error.PyverbsRDMAError: Failed to modify QP state to RTR. Errno: 22, Invalid argument ---------------------------------------------------------------------- Ran 1 test in 0.051s FAILED (errors=1) === Additional information: - VF is LAG and VF binds to host. - DC tests fail when NIC is in switchdev mode while legacy mode is fine. - Tested on 5.12 inbox driver or OFED 5.3, neither is working. - 5f:00.0 Ethernet controller [0200]: Mellanox Technologies MT2892 Family [ConnectX-6 Dx] [15b3:101d] - firmware-version: 22.30.1004 (MT_0000000536) I worked a bit tracepoint on 5.12 inbox driver. It seems like there's a firmware command error for CREATE_DCT. I can provide more information if you ask. Thanks WANG Chao
