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_l4gen.c | 110 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 110 insertions(+) create mode 100644 VNFs/DPPD-PROX/stats_l4gen.c (limited to 'VNFs/DPPD-PROX/stats_l4gen.c') diff --git a/VNFs/DPPD-PROX/stats_l4gen.c b/VNFs/DPPD-PROX/stats_l4gen.c new file mode 100644 index 00000000..37af7ac4 --- /dev/null +++ b/VNFs/DPPD-PROX/stats_l4gen.c @@ -0,0 +1,110 @@ +/* +// 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 "prox_malloc.h" +#include "prox_cfg.h" +#include "stats_l4gen.h" +#include "task_init.h" + +struct task_l4gen_stats { + struct task_base base; + struct l4_stats l4_stats; +}; + +struct stats_l4gen_manager { + uint16_t n_l4gen; + struct task_l4_stats task_l4_stats[0]; +}; + +extern int last_stat; +static struct stats_l4gen_manager *sl4m; + +int stats_get_n_l4gen(void) +{ + return sl4m->n_l4gen; +} + +struct task_l4_stats *stats_get_l4_stats(uint32_t i) +{ + return &sl4m->task_l4_stats[i]; +} + +struct l4_stats_sample *stats_get_l4_stats_sample(uint32_t i, int l) +{ + return &sl4m->task_l4_stats[i].sample[l == last_stat]; +} + +static struct stats_l4gen_manager *alloc_stats_l4gen_manager(void) +{ + struct lcore_cfg *lconf; + uint32_t lcore_id = -1; + size_t mem_size; + uint32_t n_l4gen = 0; + const int socket_id = rte_lcore_to_socket_id(rte_lcore_id()); + + 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, "genl4")) + n_l4gen++; + } + } + + mem_size = sizeof(struct stats_l4gen_manager) + sizeof(struct task_l4_stats) * n_l4gen; + return prox_zmalloc(mem_size, socket_id); +} + +void stats_l4gen_init(void) +{ + struct lcore_cfg *lconf; + uint32_t lcore_id = -1; + + sl4m = alloc_stats_l4gen_manager(); + + 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, "genl4")) { + sl4m->task_l4_stats[sl4m->n_l4gen].task = (struct task_l4gen_stats *)lconf->tasks_all[task_id]; + sl4m->task_l4_stats[sl4m->n_l4gen].lcore_id = lcore_id; + sl4m->task_l4_stats[sl4m->n_l4gen].task_id = task_id; + sl4m->n_l4gen++; + } + } + } +} + +void stats_l4gen_update(void) +{ + uint64_t before, after; + + for (uint16_t i = 0; i < sl4m->n_l4gen; ++i) { + struct task_l4gen_stats *task_l4gen = sl4m->task_l4_stats[i].task; + + before = rte_rdtsc(); + sl4m->task_l4_stats[i].sample[last_stat].stats = task_l4gen->l4_stats; + after = rte_rdtsc(); + + sl4m->task_l4_stats[i].sample[last_stat].tsc = (before >> 1) + (after >> 1); + } +} -- cgit 1.2.3-korg
