This allocation\n will be skipped when it is not required by the created template table.\n- Patches 5-7 - Reduce memory footprint of the internal flow queue.\n- Patch 8 - Remove indirection between flow job and flow itself,\n by using flow as an operation container.\n- Patches 9-10 - Reduce memory footpring of flow struct by moving\n rarely used flow fields outside of the main flow struct.\n These fields will accesses only when needed.\n Also remove unneeded `zmalloc` usage.\n- Patch 11 - Remove unneeded device status check in flow create.\n\nIn general all of these changes result in the following improvements\n(all numbers are averaged Kflows/sec):\n\n| | Insertion) | +% | Deletion | +% |\n|--------------|:----------:|:------:|:--------:|:-----:|\n| baseline | 6338.7 | | 9739.6 | |\n| improvements | 6978.8 | +10.1% | 10432.4 | +7.1% |\n\nThe basic benchmark was run on ConnectX-6 Dx (22.40.1000),\non the system with Intel Xeon Platinum 8380 CPU.\n\nBing Zhao (2):\n net/mlx5: skip the unneeded resource index allocation\n net/mlx5: remove unneeded device status checking\n\nDariusz Sosnowski (7):\n net/mlx5: allocate local DR rule action buffers\n net/mlx5: remove action params from job\n net/mlx5: remove flow pattern from job\n net/mlx5: remove updated flow from job\n net/mlx5: use flow as operation container\n net/mlx5: move rarely used flow fields outside\n net/mlx5: reuse flow fields\n\nErez Shitrit (2):\n net/mlx5/hws: add check for matcher rule update support\n net/mlx5/hws: add check if matcher contains complex rules\n\n drivers/net/mlx5/hws/mlx5dr.h | 16 +\n drivers/net/mlx5/hws/mlx5dr_action.c | 6 +\n drivers/net/mlx5/hws/mlx5dr_action.h | 2 +\n drivers/net/mlx5/hws/mlx5dr_matcher.c | 29 +\n drivers/net/mlx5/mlx5.h | 29 +-\n drivers/net/mlx5/mlx5_flow.h | 128 ++++-\n drivers/net/mlx5/mlx5_flow_hw.c | 794 ++++++++++++++++----------\n 7 files changed, 666 insertions(+), 338 deletions(-)\n\n--\n2.39.2" }
