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_global.c | 110 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 110 insertions(+) create mode 100644 VNFs/DPPD-PROX/stats_global.c (limited to 'VNFs/DPPD-PROX/stats_global.c') diff --git a/VNFs/DPPD-PROX/stats_global.c b/VNFs/DPPD-PROX/stats_global.c new file mode 100644 index 00000000..d7529d34 --- /dev/null +++ b/VNFs/DPPD-PROX/stats_global.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 +#include + +#include "stats_global.h" +#include "stats_port.h" +#include "stats_task.h" + +struct global_stats { + struct global_stats_sample sample[2]; + struct global_stats_sample beg; + uint8_t started_avg; + uint64_t start_tsc; + uint64_t end_tsc; +}; + +extern int last_stat; +static struct global_stats global_stats; + +uint64_t stats_get_last_tsc(void) +{ + return global_stats.sample[last_stat].tsc; +} + +uint64_t stats_global_start_tsc(void) +{ + return global_stats.start_tsc; +} + +uint64_t stats_global_beg_tsc(void) +{ + return global_stats.beg.tsc; +} + +uint64_t stats_global_end_tsc(void) +{ + return global_stats.end_tsc; +} + +struct global_stats_sample *stats_get_global_stats(int last) +{ + return &global_stats.sample[last == last_stat]; +} + +struct global_stats_sample *stats_get_global_stats_beg(void) +{ + return (global_stats.beg.tsc < global_stats.sample[last_stat].tsc)? &global_stats.beg : NULL; +} + +void stats_global_reset(void) +{ + uint64_t now = rte_rdtsc(); + uint64_t last_tsc = global_stats.sample[last_stat].tsc; + uint64_t prev_tsc = global_stats.sample[!last_stat].tsc; + uint64_t end_tsc = global_stats.end_tsc; + + memset(&global_stats, 0, sizeof(struct global_stats)); + global_stats.sample[last_stat].tsc = last_tsc; + global_stats.sample[!last_stat].tsc = prev_tsc; + global_stats.start_tsc = now; + global_stats.beg.tsc = now; + global_stats.end_tsc = end_tsc; +} + +void stats_global_init(unsigned avg_start, unsigned duration) +{ + uint64_t now = rte_rdtsc(); + + global_stats.start_tsc = now; + /* + 1 for rounding */ + tsc_hz = rte_get_tsc_hz(); + if (duration) + global_stats.end_tsc = global_stats.start_tsc + (avg_start + duration + 1) * tsc_hz; + + global_stats.beg.tsc = global_stats.start_tsc + avg_start * tsc_hz; +} + +void stats_global_post_proc(void) +{ + uint64_t *rx = &global_stats.sample[last_stat].host_rx_packets; + uint64_t *tx = &global_stats.sample[last_stat].host_tx_packets; + uint64_t *tsc = &global_stats.sample[last_stat].tsc; + + stats_task_get_host_rx_tx_packets(rx, tx, tsc); + global_stats.sample[last_stat].nics_ierrors = stats_port_get_ierrors(); + global_stats.sample[last_stat].nics_imissed = stats_port_get_imissed(); + global_stats.sample[last_stat].nics_rx_packets = stats_port_get_rx_packets(); + global_stats.sample[last_stat].nics_tx_packets = stats_port_get_tx_packets(); + + if (global_stats.sample[last_stat].tsc > global_stats.beg.tsc && !global_stats.started_avg) { + global_stats.started_avg = 1; + global_stats.beg = global_stats.sample[last_stat]; + } +} -- cgit 1.2.3-korg
