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/stats_prio.c | 131 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 131 insertions(+) create mode 100644 VNFs/DPPD-PROX/stats_prio.c (limited to 'VNFs/DPPD-PROX/stats_prio.c') diff --git a/VNFs/DPPD-PROX/stats_prio.c b/VNFs/DPPD-PROX/stats_prio.c new file mode 100644 index 00000000..3d39d580 --- /dev/null +++ b/VNFs/DPPD-PROX/stats_prio.c @@ -0,0 +1,131 @@ +/* +// 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 + +#include "handle_aggregator.h" +#include "stats_prio_task.h" +#include "prox_cfg.h" +#include "prox_globals.h" +#include "lconf.h" + +struct lcore_task_stats { + struct task_stats task_stats[MAX_TASKS_PER_CORE]; +}; + +struct lcore_prio_task_stats { + struct prio_task_stats prio_task_stats[MAX_TASKS_PER_CORE]; +}; + +extern int last_stat; +static struct prio_task_stats prio_task_stats_set[RTE_MAX_LCORE * MAX_TASKS_PER_CORE]; +static uint8_t nb_prio_tasks_tot; + +int stats_get_n_prio_tasks_tot(void) +{ + return nb_prio_tasks_tot; +} + +struct prio_task_stats_sample *stats_get_prio_task_stats_sample(uint32_t prio_task_id, int l) +{ + return &prio_task_stats_set[prio_task_id].sample[l == last_stat]; +} + +struct prio_task_stats_sample *stats_get_prio_task_stats_sample_by_core_task(uint32_t lcore_id, uint32_t prio_task_id, int l) +{ + for (uint8_t task_id = 0; task_id < nb_prio_tasks_tot; ++task_id) { + if ((prio_task_stats_set[task_id].lcore_id == lcore_id) && (prio_task_stats_set[task_id].task_id == task_id)) + return &prio_task_stats_set[prio_task_id].sample[l == last_stat]; + } + return NULL; +} + +void stats_prio_task_reset(void) +{ + struct prio_task_stats *cur_task_stats; + + for (uint8_t task_id = 0; task_id < nb_prio_tasks_tot; ++task_id) { + cur_task_stats = &prio_task_stats_set[task_id]; + for (int i = 0; i < 8; i++) { + cur_task_stats->tot_drop_tx_fail_prio[i] = 0; + cur_task_stats->tot_rx_prio[i] = 0; + } + } +} + +uint64_t stats_core_task_tot_drop_tx_fail_prio(uint8_t prio_task_id, uint8_t prio) +{ + return prio_task_stats_set[prio_task_id].tot_drop_tx_fail_prio[prio]; +} + +uint64_t stats_core_task_tot_rx_prio(uint8_t prio_task_id, uint8_t prio) +{ + return prio_task_stats_set[prio_task_id].tot_rx_prio[prio]; +} + +void stats_prio_task_post_proc(void) +{ + for (uint8_t task_id = 0; task_id < nb_prio_tasks_tot; ++task_id) { + struct prio_task_stats *cur_task_stats = &prio_task_stats_set[task_id]; + const struct prio_task_stats_sample *last = &cur_task_stats->sample[last_stat]; + const struct prio_task_stats_sample *prev = &cur_task_stats->sample[!last_stat]; + + for (int i=0; i<8; i++) { + cur_task_stats->tot_rx_prio[i] += last->rx_prio[i] - prev->rx_prio[i]; + cur_task_stats->tot_drop_tx_fail_prio[i] += last->drop_tx_fail_prio[i] - prev->drop_tx_fail_prio[i]; + } + } +} + +void stats_prio_task_update(void) +{ + uint64_t before, after; + + for (uint8_t task_id = 0; task_id < nb_prio_tasks_tot; ++task_id) { + struct prio_task_stats *cur_task_stats = &prio_task_stats_set[task_id]; + struct prio_task_rt_stats *stats = cur_task_stats->stats; + struct prio_task_stats_sample *last = &cur_task_stats->sample[last_stat]; + + before = rte_rdtsc(); + for (int i=0; i<8; i++) { + last->drop_tx_fail_prio[i] = stats->drop_tx_fail_prio[i]; + last->rx_prio[i] = stats->rx_prio[i]; + } + after = rte_rdtsc(); + last->tsc = (before >> 1) + (after >> 1); + } +} + +void stats_prio_task_init(void) +{ + struct lcore_cfg *lconf; + uint32_t lcore_id; + + /* add cores that are receiving from and sending to physical ports first */ + lcore_id = -1; + while(prox_core_next(&lcore_id, 0) == 0) { + lconf = &lcore_cfg[lcore_id]; + for (uint8_t task_id = 0; task_id < lconf->n_tasks_all; ++task_id) { + struct task_args *targ = &lconf->targs[task_id]; + if (strcmp(targ->task_init->mode_str, "aggreg") == 0) { + struct prio_task_rt_stats *stats = &((struct task_aggregator *)(lconf->tasks_all[task_id]))->stats; + prio_task_stats_set[nb_prio_tasks_tot].stats = stats; + prio_task_stats_set[nb_prio_tasks_tot].lcore_id = lcore_id; + prio_task_stats_set[nb_prio_tasks_tot++].task_id = task_id; + } + } + } +} -- cgit 1.2.3-korg
