From f3468975d837fbe07c11c55d6ce7a6bf756ea2d8 Mon Sep 17 00:00:00 2001 From: Chenmin Sun Date: Fri, 6 Mar 2020 23:09:32 +0800 Subject: dpdk: tx/rx burst function description refactor DPDK provides two new APIs to retrieve information about the Tx/Rx packet burst mode: rte_eth_tx_burst_mode_get rte_eth_rx_burst_mode_get This patch leverages these two APIs to describe the tx/rx mode. Currently, Intel X710/E810 and Mellanox Mlx5 support the new APIs. For NICs that don't support the new APIs, still use the original way to print their tx/rx function name Type: refactor Signed-off-by: Chenmin Sun Change-Id: Ibe47f5debe3b3f17f462fbf9834394e22845cc08 --- src/plugins/dpdk/device/format.c | 37 +++++++++++++++++++++++++++++++------ 1 file changed, 31 insertions(+), 6 deletions(-) diff --git a/src/plugins/dpdk/device/format.c b/src/plugins/dpdk/device/format.c index 0db58d8ec2f..693f92d4a81 100644 --- a/src/plugins/dpdk/device/format.c +++ b/src/plugins/dpdk/device/format.c @@ -568,6 +568,7 @@ format_dpdk_device (u8 * s, va_list * args) u32 indent = format_get_indent (s); f64 now = vlib_time_now (dm->vlib_main); struct rte_eth_dev_info di; + struct rte_eth_burst_mode mode; dpdk_update_counters (xd, now); dpdk_update_link_state (xd, now); @@ -666,12 +667,36 @@ format_dpdk_device (u8 * s, va_list * args) format_dpdk_rss_hf_name, di.flow_type_rss_offloads, format_white_space, indent + 2, format_dpdk_rss_hf_name, rss_conf.rss_hf); - s = format (s, "%Utx burst function: %s\n", - format_white_space, indent + 2, - ptr2sname (rte_eth_devices[xd->port_id].tx_pkt_burst)); - s = format (s, "%Urx burst function: %s\n", - format_white_space, indent + 2, - ptr2sname (rte_eth_devices[xd->port_id].rx_pkt_burst)); + + if (rte_eth_tx_burst_mode_get (xd->port_id, 0, &mode) == 0) + { + s = format (s, "%Utx burst mode: %s%s\n", + format_white_space, indent + 2, + mode.info, + mode.flags & RTE_ETH_BURST_FLAG_PER_QUEUE ? + " (per queue)" : ""); + } + else + { + s = format (s, "%Utx burst function: %s\n", + format_white_space, indent + 2, + ptr2sname (rte_eth_devices[xd->port_id].tx_pkt_burst)); + } + + if (rte_eth_rx_burst_mode_get (xd->port_id, 0, &mode) == 0) + { + s = format (s, "%Urx burst mode: %s%s\n", + format_white_space, indent + 2, + mode.info, + mode.flags & RTE_ETH_BURST_FLAG_PER_QUEUE ? + " (per queue)" : ""); + } + else + { + s = format (s, "%Urx burst function: %s\n", + format_white_space, indent + 2, + ptr2sname (rte_eth_devices[xd->port_id].rx_pkt_burst)); + } } /* $$$ MIB counters */ -- cgit 1.2.3-korg
