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/hash_utils.h | 42 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) create mode 100644 VNFs/DPPD-PROX/hash_utils.h (limited to 'VNFs/DPPD-PROX/hash_utils.h') diff --git a/VNFs/DPPD-PROX/hash_utils.h b/VNFs/DPPD-PROX/hash_utils.h new file mode 100644 index 00000000..a2536ffb --- /dev/null +++ b/VNFs/DPPD-PROX/hash_utils.h @@ -0,0 +1,42 @@ +/* +// 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. +*/ + +#ifndef _HASH_UTILS_H_ +#define _HASH_UTILS_H_ + +#include +#include + +struct rte_table_hash; + +/* Take DPDK 2.2.0 ABI change into account: offset 0 now means first byte of mbuf struct + * see http://www.dpdk.org/browse/dpdk/commit/?id=ba92d511ddacf863fafaaa14c0577f30ee57d092 + */ +#if RTE_VERSION >= RTE_VERSION_NUM(2,2,0,0) +#define HASH_METADATA_OFFSET(offset) (sizeof(struct rte_mbuf) + (offset)) +#else +#define HASH_METADATA_OFFSET(offset) (offset) +#endif + +/* Wrap crc32 hash function to match that required for rte_table */ +uint64_t hash_crc32(void* key, uint32_t key_size, uint64_t seed); + +void print_hash_table_size(const struct rte_table_hash *h); +void print_hash_table(const struct rte_table_hash *h); + +uint64_t get_bucket_key8(void* table, uint32_t bucket_idx, void** key, void** entries); +uint64_t get_bucket(void* table, uint32_t bucket_idx, void** key, void** entries); +#endif /* _HASH_UTILS_H_ */ -- cgit 1.2.3-korg
