As checked again, still feels like adding unnecessary complexity, and I am for rejecting this series. Overall target is to be able to support hotplug with primary/secondary process, and uses event handlers for this but this requires adding a new ethdev state to be able iterate over devices etc... Perhaps better way to support this without relying on event handlers. > /Huisong > > > 在 2024/9/29 13:52, Huisong Li 写道: >> This patchset fix some bugs and support attaching and detaching port >> in primary and secondary. >> >> --- >>   -v7: fix conflicts >>   -v6: adjust rte_eth_dev_is_used position based on alphabetical order >>        in version.map >>   -v5: move 'ALLOCATED' state to the back of 'REMOVED' to avoid abi >> break. >>   -v4: fix a misspelling. >>   -v3: >>     #1 merge patch 1/6 and patch 2/6 into patch 1/5, and add modification >>        for other bus type. >>     #2 add a RTE_ETH_DEV_ALLOCATED state in rte_eth_dev_state to resolve >>        the probelm in patch 2/5. >>   -v2: resend due to CI unexplained failure. >> >> Huisong Li (5): >>    drivers/bus: restore driver assignment at front of probing >>    ethdev: fix skip valid port in probing callback >>    app/testpmd: check the validity of the port >>    app/testpmd: add attach and detach port for multiple process >>    app/testpmd: stop forwarding in new or destroy event >> >>   app/test-pmd/testpmd.c                   | 47 +++++++++++++++--------- >>   app/test-pmd/testpmd.h                   |  1 - >>   drivers/bus/auxiliary/auxiliary_common.c |  9 ++++- >>   drivers/bus/dpaa/dpaa_bus.c              |  9 ++++- >>   drivers/bus/fslmc/fslmc_bus.c            |  8 +++- >>   drivers/bus/ifpga/ifpga_bus.c            | 12 ++++-- >>   drivers/bus/pci/pci_common.c             |  9 ++++- >>   drivers/bus/vdev/vdev.c                  | 10 ++++- >>   drivers/bus/vmbus/vmbus_common.c         |  9 ++++- >>   drivers/net/bnxt/bnxt_ethdev.c           |  3 +- >>   drivers/net/bonding/bonding_testpmd.c    |  1 - >>   drivers/net/mlx5/mlx5.c                  |  2 +- >>   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 + >>   19 files changed, 114 insertions(+), 44 deletions(-) >>
