Firmware uses a\nglobal counter to assign txq affinity to different\nphysical ports accord to remainder after division.\n\nThere are three dis-advantages:\n1. The global counter is shared between kernel and dpdk.\n2. After restarting pmd or port, the previous counter value\nis reused, so the new affinity is unpredictable.\n3. There is no way to get what affinity is set by firmware.\n\nIn this update, we will create several TISs up to the\nnumber of bonding ports and bind each TIS to one PF port.\n\nFor each port, it will start to pick up TIS using its port\nindex. Upper layer application can quickly calculate each txq's\naffinity without querying.\n\nAt DPDK layer, when creating txq with 2 bonding ports, the\naffinity is set like:\nport 0: 1-->2-->1-->2\nport 1: 2-->1-->2-->1\nport 2: 1-->2-->1-->2\n\nNote: Only applicable to Devx api.\n\nRongwei Liu (1):\n net/mlx5: set txq affinity in round-robin\n\n drivers/common/mlx5/mlx5_devx_cmds.c | 38 ++++++++++++++++++++++\n drivers/common/mlx5/mlx5_devx_cmds.h | 12 +++++++\n drivers/common/mlx5/mlx5_prm.h | 26 +++++++++++++++\n drivers/common/mlx5/version.map | 1 +\n drivers/net/mlx5/linux/mlx5_os.c | 37 ++++++++++++++++++++++\n drivers/net/mlx5/mlx5.c | 17 +++-------\n drivers/net/mlx5/mlx5.h | 8 ++++-\n drivers/net/mlx5/mlx5_devx.c | 47 ++++++++++++++++++++++++++--\n drivers/net/mlx5/mlx5_tx.h | 1 +\n drivers/net/mlx5/mlx5_txpp.c | 4 +--\n 10 files changed, 174 insertions(+), 17 deletions(-)", "diff": null, "prefixes": [ "RFC", "0/1" ] }
