Because alloc mbuf failed, the rx_nombuf field is counted. Signed-off-by: Qiming Chen --- v2: Clear coding style issues. v3: 1) Send direction does not release mbuf. 2) Failed to alloc mbuf is counted to the rx_nombuf field. v4: Add rx_nombuf field. --- drivers/net/pcap/pcap_ethdev.c | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-) diff --git a/drivers/net/pcap/pcap_ethdev.c b/drivers/net/pcap/pcap_ethdev.c index a8774b7a43..47db6b9b33 100644 --- a/drivers/net/pcap/pcap_ethdev.c +++ b/drivers/net/pcap/pcap_ethdev.c @@ -51,6 +51,7 @@ struct queue_stat { volatile unsigned long pkts; volatile unsigned long bytes; volatile unsigned long err_pkts; + volatile unsigned long rx_nombuf; }; struct queue_missed_stat { @@ -297,8 +298,10 @@ eth_pcap_rx(void *queue, struct rte_mbuf **bufs, uint16_t nb_pkts) break; mbuf = rte_pktmbuf_alloc(pcap_q->mb_pool); - if (unlikely(mbuf == NULL)) - break; + if (unlikely(mbuf == NULL)) { + pcap_q->rx_stat.rx_nombuf++; + continue; + } if (header.caplen <= rte_pktmbuf_tailroom(mbuf)) { /* pcap packet will fit in the mbuf, can copy it */ @@ -311,6 +314,7 @@ eth_pcap_rx(void *queue, struct rte_mbuf **bufs, uint16_t nb_pkts) mbuf, packet, header.caplen) == -1)) { + pcap_q->rx_stat.rx_nombuf++; rte_pktmbuf_free(mbuf); break; } @@ -742,7 +746,7 @@ eth_stats_get(struct rte_eth_dev *dev, struct rte_eth_stats *stats) { unsigned int i; unsigned long rx_packets_total = 0, rx_bytes_total = 0; - unsigned long rx_missed_total = 0; + unsigned long rx_missed_total = 0, rx_nombuf = 0; unsigned long tx_packets_total = 0, tx_bytes_total = 0; unsigned long tx_packets_err_total = 0; const struct pmd_internals *internal = dev->data->dev_private; @@ -751,6 +755,7 @@ eth_stats_get(struct rte_eth_dev *dev, struct rte_eth_stats *stats) i < dev->data->nb_rx_queues; i++) { stats->q_ipackets[i] = internal->rx_queue[i].rx_stat.pkts; stats->q_ibytes[i] = internal->rx_queue[i].rx_stat.bytes; + rx_nombuf += internal->rx_queue[i].rx_stat.rx_nombuf; rx_packets_total += stats->q_ipackets[i]; rx_bytes_total += stats->q_ibytes[i]; rx_missed_total += queue_missed_stat_get(dev, i); @@ -771,6 +776,7 @@ eth_stats_get(struct rte_eth_dev *dev, struct rte_eth_stats *stats) stats->opackets = tx_packets_total; stats->obytes = tx_bytes_total; stats->oerrors = tx_packets_err_total; + stats->rx_nombuf = rx_nombuf; return 0; } @@ -784,6 +790,8 @@ eth_stats_reset(struct rte_eth_dev *dev) for (i = 0; i < dev->data->nb_rx_queues; i++) { internal->rx_queue[i].rx_stat.pkts = 0; internal->rx_queue[i].rx_stat.bytes = 0; + internal->rx_queue[i].rx_stat.err_pkts = 0; + internal->rx_queue[i].rx_stat.rx_nombuf = 0; queue_missed_stat_reset(dev, i); } -- 2.30.1.windows.1
