From 7286b2518ec8e4398b512ce95def9166a7af2e4a Mon Sep 17 00:00:00 2001 From: Deepak S Date: Thu, 13 Jul 2017 21:26:50 -0700 Subject: Adding PROX(Packet pROcessing eXecution engine) VNF to sampleVNF JIRA: SAMPLEVNF-55 PROX is a DPDK-based application implementing Telco use-cases such as a simplified BRAS/BNG, light-weight AFTR... It also allows configuring finer grained network functions like QoS, Routing, load-balancing... (We are moving PROX version v039 to sampleVNF https://01.org/intel-data-plane-performance-demonstrators/prox-overview) Change-Id: Ia3cb02cf0e49ac5596e922c197ff7e010293d033 Signed-off-by: Deepak S --- VNFs/DPPD-PROX/display_pkt_len.c | 138 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 138 insertions(+) create mode 100644 VNFs/DPPD-PROX/display_pkt_len.c (limited to 'VNFs/DPPD-PROX/display_pkt_len.c') diff --git a/VNFs/DPPD-PROX/display_pkt_len.c b/VNFs/DPPD-PROX/display_pkt_len.c new file mode 100644 index 00000000..df34616a --- /dev/null +++ b/VNFs/DPPD-PROX/display_pkt_len.c @@ -0,0 +1,138 @@ +/* +// Copyright (c) 2010-2017 Intel Corporation +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. +*/ + +#include "prox_globals.h" +#include "display_pkt_len.h" +#include "stats_port.h" +#include "display.h" +#include "defaults.h" +#include "prox_port_cfg.h" +#include "clock.h" + +static struct display_page display_page_pkt_len; +static struct display_column *port_col; +static struct display_column *name_col; +static struct display_column *type_col; +static struct display_column *stats_col[PKT_SIZE_COUNT]; + +const char *titles[] = { + "64B (#)", + "65-127B (#)", + "128-255B (#)", + "256-511B (#)", + "512-1023B (#)", + "1024-1522B (#)", + "1523B+ (#)", +}; + +static int port_disp[PROX_MAX_PORTS]; +static int n_port_disp; + +static void display_pkt_len_draw_frame(struct screen_state *screen_state) +{ + n_port_disp = 0; + for (uint8_t i = 0; i < PROX_MAX_PORTS; ++i) { + if (prox_port_cfg[i].active) { + port_disp[n_port_disp++] = i; + } + } + + display_page_init(&display_page_pkt_len); + + struct display_table *port_name = display_page_add_table(&display_page_pkt_len); + + display_table_init(port_name, "Port"); + port_col = display_table_add_col(port_name); + name_col = display_table_add_col(port_name); + type_col = display_table_add_col(port_name); + + display_column_init(port_col, "ID", 4); + display_column_init(name_col, "Name", 8); + display_column_init(type_col, "Type", 7); + + struct display_table *stats = display_page_add_table(&display_page_pkt_len); + + if (screen_state->toggle == 0) + display_table_init(stats, "Statistics per second"); + else + display_table_init(stats, "Total Statistics"); + + for (int i = 0; i < PKT_SIZE_COUNT; ++i) { + stats_col[i] = display_table_add_col(stats); + display_column_init(stats_col[i], titles[i], 13); + } + + display_page_draw_frame(&display_page_pkt_len, n_port_disp); + + for (uint8_t i = 0; i < n_port_disp; ++i) { + const uint32_t port_id = port_disp[i]; + + display_column_print(port_col, i, "%4u", port_id); + display_column_print(name_col, i, "%8s", prox_port_cfg[port_id].name); + display_column_print(type_col, i, "%7s", prox_port_cfg[port_id].short_name); + } +} + +static void display_pkt_len_draw_stats(struct screen_state *state) +{ + for (uint8_t i = 0; i < n_port_disp; ++i) { + const uint32_t port_id = port_disp[i]; + struct port_stats_sample *last = stats_get_port_stats_sample(port_id, 1); + struct port_stats_sample *prev = stats_get_port_stats_sample(port_id, 0); + + uint64_t delta_t = last->tsc - prev->tsc; + if (delta_t == 0) // This could happen if we just reset the screen => stats will be updated later + continue; + + if (state->toggle == 0) { + uint64_t diff; + + for (int j = 0; j < PKT_SIZE_COUNT; ++j) { + if (last->tx_pkt_size[j] == (uint64_t)-1) { + display_column_print(stats_col[j], i, " --- "); + } else { + diff = last->tx_pkt_size[j] - prev->tx_pkt_size[j]; + display_column_print(stats_col[j], i, "%13lu", val_to_rate(diff, delta_t)); + } + } + } else { + for (int j = 0; j < PKT_SIZE_COUNT; ++j) { + if (last->tx_pkt_size[j] == (uint64_t)-1) { + display_column_print(stats_col[j], i, " --- "); + } else { + display_column_print(stats_col[j], i, "%13lu", last->tx_pkt_size[j]); + } + } + } + } +} + +static int display_pkt_len_get_height(void) +{ + return stats_get_n_ports(); +} + +static struct display_screen display_screen_pkt_len = { + .draw_frame = display_pkt_len_draw_frame, + .draw_stats = display_pkt_len_draw_stats, + .get_height = display_pkt_len_get_height, + .title = "pkt_len", +}; + +struct display_screen *display_pkt_len(void) +{ + return &display_screen_pkt_len; +} -- cgit 1.2.3-korg
