>From 9ca4302dd93461a7b01ad05af82ee2bcadf47675 Mon Sep 17 00:00:00 2001 From: Mohand Alrasheed <[email protected]> Date: Mon, 5 Jan 2026 15:44:25 +0300 Subject: [PATCH] net/mlx5: fix offset handling in mlx5_aso_cnt_sq_enqueue_burst
mlx5_aso_cnt_sq_enqueue_burst() selects the ASO counter block using dcs_id_base/4 and ignores the batch offset. This causes every batch to target the first counter block, leading to counter aliasing (e.g. 2^16 matches 0). This patch selects the counter block using the offset-adjusted index. Reproducible example: https://github.com/Hawzen/rte-flow-async-profiling/blob/5e654e3a8a0414a5fa8ed43274195f180760f0b5/examples/flow_filtering/reproduce.md Fixes: 4d368e1da3a453cbcac620e8844c0300b2f45cfa Cc: [email protected] Cc: [email protected] --- drivers/net/mlx5/mlx5_flow_aso.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/net/mlx5/mlx5_flow_aso.c b/drivers/net/mlx5/mlx5_flow_aso.c index feca8c3e89..a232289024 100644 --- a/drivers/net/mlx5/mlx5_flow_aso.c +++ b/drivers/net/mlx5/mlx5_flow_aso.c @@ -1877,6 +1877,7 @@ mlx5_aso_cnt_sq_enqueue_burst(struct mlx5_hws_cnt_pool *cpool, sq->elts[0].burst_size = max; ctrl_gen_id = dcs_id_base; ctrl_gen_id /= 4; + ctrl_gen_id += offset / 4; do { ccntid = upper_offset - max * 4; wqe = &sq->sq_obj.aso_wqes[sq->head & mask]; -- 2.39.5
