After we check the validity of the port in eth_event_callback() of testpmd like patch 1/2, testpmd attach one port and doesn't update total port number maintained in testmd. See the following log: --- testpmd> testpmd> port attach 0000:7d:00.1 Attaching a new port... testpmd> testpmd> port start all Port 0 is now not stopped ETHDEV: Device with port_id=1 is not configured. Fail to start port 1: Invalid argument Done ---
For details about the root cause of this issue, please see the patch 2/2. After merging the patch 2/2. this issue can be fixed and the log is as follows: --- testpmd> testpmd> port attach 0000:7d:00.1 Attaching a new port... Port 1 is attached. Now total ports is 2 Done --- BTW, the modification method for this issue is from the following thread. https://mails.dpdk.org/archives/dev/2024-January/286026.html Huisong Li (2): app/testpmd: check the validity of the port ethdev: fix skip valid port in probing callback app/test-pmd/testpmd.c | 5 +++-- drivers/net/bnxt/bnxt_ethdev.c | 2 +- drivers/net/cpfl/cpfl_ethdev.h | 2 +- drivers/net/ionic/ionic_ethdev.c | 2 +- drivers/net/mlx5/mlx5.c | 2 +- drivers/net/nfp/nfp_ethdev.c | 4 ++-- lib/ethdev/ethdev_driver.c | 13 ++++++++++--- lib/ethdev/ethdev_driver.h | 12 ++++++++++++ lib/ethdev/ethdev_pci.h | 2 +- lib/ethdev/rte_class_eth.c | 2 +- lib/ethdev/rte_ethdev.c | 4 ++-- lib/ethdev/rte_ethdev.h | 4 +++- lib/ethdev/version.map | 1 + 13 files changed, 39 insertions(+), 16 deletions(-) -- 2.22.0
