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/thread_nop.c | 66 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 66 insertions(+) create mode 100644 VNFs/DPPD-PROX/thread_nop.c (limited to 'VNFs/DPPD-PROX/thread_nop.c') diff --git a/VNFs/DPPD-PROX/thread_nop.c b/VNFs/DPPD-PROX/thread_nop.c new file mode 100644 index 00000000..ba30dc61 --- /dev/null +++ b/VNFs/DPPD-PROX/thread_nop.c @@ -0,0 +1,66 @@ +/* +// 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 "log.h" +#include "lconf.h" +#include "thread_nop.h" +#include "handle_nop.h" +#include "stats.h" +#include "lconf.h" +#include "defines.h" + +int thread_nop(struct lcore_cfg *lconf) +{ + struct task_base *tasks[MAX_TASKS_PER_CORE]; + struct rte_mbuf **mbufs; + uint64_t cur_tsc = rte_rdtsc(); + uint64_t term_tsc = cur_tsc; + uint64_t drain_tsc = cur_tsc; + uint8_t n_tasks_run = 0; + + for (;;) { + cur_tsc = rte_rdtsc(); + if (cur_tsc > term_tsc) { + term_tsc = cur_tsc + TERM_TIMEOUT; + if (lconf_is_req(lconf) && lconf_do_flags(lconf)) { + n_tasks_run = lconf->n_tasks_run; + + if (!n_tasks_run) + return 0; + for (int i = 0; i < lconf->n_tasks_run; ++i) { + tasks[i] = lconf->tasks_run[i]; + } + } + } + if (cur_tsc > drain_tsc) { + drain_tsc = cur_tsc + DRAIN_TIMEOUT; + lconf_flush_all_queues(lconf); + } + + for (uint8_t task_id = 0; task_id < n_tasks_run; ++task_id) { + struct task_base *t = tasks[task_id]; + uint16_t nb_rx = t->rx_pkt(t, &mbufs); + + if (likely(nb_rx)) { + handle_nop_bulk(t, mbufs, nb_rx); + } + } + } + + return 0; +} -- cgit 1.2.3-korg
