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/handle_tsc.c | 51 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 VNFs/DPPD-PROX/handle_tsc.c (limited to 'VNFs/DPPD-PROX/handle_tsc.c') diff --git a/VNFs/DPPD-PROX/handle_tsc.c b/VNFs/DPPD-PROX/handle_tsc.c new file mode 100644 index 00000000..e686aaa2 --- /dev/null +++ b/VNFs/DPPD-PROX/handle_tsc.c @@ -0,0 +1,51 @@ +/* +// 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 + +#include "task_base.h" +#include "task_init.h" +#include "thread_generic.h" + +struct task_tsc { + struct task_base base; +}; + +static int handle_bulk_tsc(struct task_base *tbase, struct rte_mbuf **mbufs, uint16_t n_pkts) +{ + struct task_tsc *task = (struct task_tsc *)tbase; + const uint64_t rx_tsc = rte_rdtsc(); + + for (uint16_t j = 0; j < n_pkts; ++j) + mbufs[j]->udata64 = rx_tsc; + + return task->base.tx_pkt(&task->base, mbufs, n_pkts, NULL); +} + +static struct task_init task_init = { + .mode_str = "tsc", + .init = NULL, + .handle = handle_bulk_tsc, + .flag_features = TASK_FEATURE_NEVER_DISCARDS|TASK_FEATURE_TXQ_FLAGS_NOOFFLOADS|TASK_FEATURE_TXQ_FLAGS_NOMULTSEGS|TASK_FEATURE_THROUGHPUT_OPT, + .size = sizeof(struct task_tsc), + .mbuf_size = 2048 + sizeof(struct rte_mbuf) + RTE_PKTMBUF_HEADROOM, +}; + +__attribute__((constructor)) static void reg_task_nop(void) +{ + reg_task(&task_init); +} -- cgit 1.2.3-korg
