From fa876f3ae29885321c752468c22ad1c06a7a498c Mon Sep 17 00:00:00 2001 From: Liron Himi Date: Wed, 27 Jan 2021 18:09:16 +0200 Subject: [PATCH] net/mvpp2: remove debug log on fast-path In case of non-ip frame the current code reached the 'default' case which result with function call to log a msg. Those kind of calls should not be performed on fast-path. The performance for this kind of frames increased by 50% Fixes: acab7d58c81b ("net/mvpp2: convert to dynamic logging") Cc: stable@dpdk.org Signed-off-by: Liron Himi --- drivers/net/mvpp2/mrvl_ethdev.c | 27 ++++----------------------- 1 file changed, 4 insertions(+), 23 deletions(-) diff --git a/drivers/net/mvpp2/mrvl_ethdev.c b/drivers/net/mvpp2/mrvl_ethdev.c index 2f5b2f256b..a564752a57 100644 --- a/drivers/net/mvpp2/mrvl_ethdev.c +++ b/drivers/net/mvpp2/mrvl_ethdev.c @@ -2171,7 +2171,6 @@ mrvl_desc_to_packet_type_and_offset(struct pp2_ppio_desc *desc, *l4_offset = *l3_offset + MRVL_ARP_LENGTH; break; default: - MRVL_LOG(DEBUG, "Failed to recognise l3 packet type"); break; } @@ -2183,7 +2182,6 @@ mrvl_desc_to_packet_type_and_offset(struct pp2_ppio_desc *desc, packet_type |= RTE_PTYPE_L4_UDP; break; default: - MRVL_LOG(DEBUG, "Failed to recognise l4 packet type"); break; } @@ -2253,10 +2251,9 @@ mrvl_rx_pkt_burst(void *rxq, struct rte_mbuf **rx_pkts, uint16_t nb_pkts) ret = pp2_ppio_recv(q->priv->ppio, q->priv->rxq_map[q->queue_id].tc, q->priv->rxq_map[q->queue_id].inq, descs, &nb_pkts); - if (unlikely(ret < 0)) { - MRVL_LOG(ERR, "Failed to receive packets"); + if (unlikely(ret < 0)) return 0; - } + mrvl_port_bpool_size[bpool->pp2_id][bpool->id][core_id] -= nb_pkts; for (i = 0; i < nb_pkts; i++) { @@ -2319,21 +2316,13 @@ mrvl_rx_pkt_burst(void *rxq, struct rte_mbuf **rx_pkts, uint16_t nb_pkts) if (unlikely(num <= q->priv->bpool_min_size || (!rx_done && num < q->priv->bpool_init_size))) { - ret = mrvl_fill_bpool(q, MRVL_BURST_SIZE); - if (ret) - MRVL_LOG(ERR, "Failed to fill bpool"); + mrvl_fill_bpool(q, MRVL_BURST_SIZE); } else if (unlikely(num > q->priv->bpool_max_size)) { int i; int pkt_to_remove = num - q->priv->bpool_init_size; struct rte_mbuf *mbuf; struct pp2_buff_inf buff; - MRVL_LOG(DEBUG, - "port-%d:%d: bpool %d oversize - remove %d buffers (pool size: %d -> %d)", - bpool->pp2_id, q->priv->ppio->port_id, - bpool->id, pkt_to_remove, num, - q->priv->bpool_init_size); - for (i = 0; i < pkt_to_remove; i++) { ret = pp2_bpool_get_buff(hif, bpool, &buff); if (ret) @@ -2526,12 +2515,8 @@ mrvl_tx_pkt_burst(void *txq, struct rte_mbuf **tx_pkts, uint16_t nb_pkts) sq, q->queue_id, 0); sq_free_size = MRVL_PP2_TX_SHADOWQ_SIZE - sq->size - 1; - if (unlikely(nb_pkts > sq_free_size)) { - MRVL_LOG(DEBUG, - "No room in shadow queue for %d packets! %d packets will be sent.", - nb_pkts, sq_free_size); + if (unlikely(nb_pkts > sq_free_size)) nb_pkts = sq_free_size; - } for (i = 0; i < nb_pkts; i++) { struct rte_mbuf *mbuf = tx_pkts[i]; @@ -2648,10 +2633,6 @@ mrvl_tx_sg_pkt_burst(void *txq, struct rte_mbuf **tx_pkts, */ if (unlikely(total_descs > sq_free_size)) { total_descs -= nb_segs; - RTE_LOG(DEBUG, PMD, - "No room in shadow queue for %d packets!
