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/clock.h | 76 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 76 insertions(+) create mode 100644 VNFs/DPPD-PROX/clock.h (limited to 'VNFs/DPPD-PROX/clock.h') diff --git a/VNFs/DPPD-PROX/clock.h b/VNFs/DPPD-PROX/clock.h new file mode 100644 index 00000000..719968ab --- /dev/null +++ b/VNFs/DPPD-PROX/clock.h @@ -0,0 +1,76 @@ +/* +// 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 _CLOCK_H_ +#define _CLOCK_H_ + +#include + +extern uint32_t rdtsc_overhead; +extern uint32_t rdtsc_overhead_stats; + +void clock_init(void); + +struct time_unit { + uint64_t sec; + uint64_t nsec; +}; + +struct time_unit_err { + struct time_unit time; + struct time_unit error; +}; + +extern uint64_t thresh; +extern uint64_t tsc_hz; + +static uint64_t val_to_rate(uint64_t val, uint64_t delta_t) +{ + if (val < thresh) { + return val * tsc_hz / delta_t; + } else if (val >> 2 < thresh) { + /* bytes per sec malls into this category ... */ + return ((val >> 2) * tsc_hz) / (delta_t >> 2); + } else { + if (delta_t < tsc_hz) + return UINT64_MAX; + else + return val / (delta_t/tsc_hz); + } +} + +/* The precision of the conversion is nano-second. */ +uint64_t str_to_tsc(const char *from); +uint64_t sec_to_tsc(uint64_t sec); +uint64_t msec_to_tsc(uint64_t msec); +uint64_t usec_to_tsc(uint64_t usec); +uint64_t nsec_to_tsc(uint64_t nsec); +uint64_t freq_to_tsc(uint64_t times_per_sec); +uint64_t tsc_to_msec(uint64_t tsc); +uint64_t tsc_to_usec(uint64_t tsc); +uint64_t tsc_to_nsec(uint64_t tsc); +uint64_t tsc_to_sec(uint64_t tsc); +struct time_unit tsc_to_time_unit(uint64_t tsc); +uint64_t time_unit_to_usec(struct time_unit *time_unit); +uint64_t time_unit_to_nsec(struct time_unit *time_unit); +int time_unit_cmp(struct time_unit *left, struct time_unit *right); + +struct timeval; +void tsc_to_tv(struct timeval *tv, const uint64_t tsc); +void tv_to_tsc(const struct timeval *tv, uint64_t *tsc); +struct timeval tv_diff(const struct timeval *tv1, const struct timeval * tv2); + +#endif /* _CLOCK_H_ */ -- cgit 1.2.3-korg
