The original items remain in the prefix sub flow, add the implicit tag action with unique id to set in metadata register, and suffix sub flow uses the tag item to match with that unique id. The flow split as below: Original flow: items / actions pre / sample / actions sfx -> prefix sub flow - items / actions pre / set_tag action / sample suffix sub flow - tag_item / actions sfx Signed-off-by: Jiawei Wang Acked-by: Viacheslav Ovsiienko --- drivers/net/mlx5/mlx5.c | 11 ++ drivers/net/mlx5/mlx5.h | 3 + drivers/net/mlx5/mlx5_flow.c | 360 +++++++++++++++++++++++++++++++++++++++++-- drivers/net/mlx5/mlx5_flow.h | 37 +++++ 4 files changed, 394 insertions(+), 17 deletions(-) diff --git a/drivers/net/mlx5/mlx5.c b/drivers/net/mlx5/mlx5.c index e5ca392..2613c78 100644 --- a/drivers/net/mlx5/mlx5.c +++ b/drivers/net/mlx5/mlx5.c @@ -241,6 +241,17 @@ static LIST_HEAD(, mlx5_dev_ctx_shared) mlx5_dev_ctx_list = .free = mlx5_free, .type = "mlx5_jump_ipool", }, + { + .size = sizeof(struct mlx5_flow_dv_sample_resource), + .trunk_size = 64, + .grow_trunk = 3, + .grow_shift = 2, + .need_lock = 0, + .release_mem_en = 1, + .malloc = mlx5_malloc, + .free = mlx5_free, + .type = "mlx5_sample_ipool", + }, #endif { .size = sizeof(struct mlx5_flow_meter), diff --git a/drivers/net/mlx5/mlx5.h b/drivers/net/mlx5/mlx5.h index 375c86e..391f6f3 100644 --- a/drivers/net/mlx5/mlx5.h +++ b/drivers/net/mlx5/mlx5.h @@ -39,6 +39,7 @@ enum mlx5_ipool_index { MLX5_IPOOL_TAG, /* Pool for tag resource. */ MLX5_IPOOL_PORT_ID, /* Pool for port id resource. */ MLX5_IPOOL_JUMP, /* Pool for jump resource. */ + MLX5_IPOOL_SAMPLE, /* Pool for sample resource. */ #endif MLX5_IPOOL_MTR, /* Pool for meter resource. */ MLX5_IPOOL_MCP, /* Pool for metadata resource. */ @@ -512,6 +513,7 @@ struct mlx5_flow_tbl_resource { #define MLX5_FLOW_TABLE_LEVEL_METER (MLX5_MAX_TABLES - 4) #define MLX5_FLOW_TABLE_LEVEL_SUFFIX (MLX5_MAX_TABLES - 3) #define MLX5_MAX_TABLES_FDB UINT16_MAX +#define MLX5_FLOW_TABLE_FACTOR 10 /* ID generation structure. */ struct mlx5_flow_id_pool { @@ -640,6 +642,7 @@ struct mlx5_dev_ctx_shared { struct mlx5_hlist *tag_table;
