C++ (Cpp) tv_to_cycles Beispiele

Beispiel #1

Datei: ext_hotprofiler.cpp Projekt: oxromantic/hiphop-php

static inline uint64 vtsc(int64 MHz) {
  if (vtsc_syscall.num > 0) {
    return syscall(vtsc_syscall.num);
  }
  struct rusage usage;
  getrusage(RUSAGE_SELF, &usage);
  return
    tv_to_cycles(usage.ru_utime, MHz) + tv_to_cycles(usage.ru_stime, MHz);
}

Beispiel #2

Datei: ext_hotprofiler.cpp Projekt: XBS-Nathan/hhvm

static inline uint64_t cpuTime(int64_t MHz) {
#ifdef CLOCK_THREAD_CPUTIME_ID
  int64_t rval = Vdso::ClockGetTimeNS(CLOCK_THREAD_CPUTIME_ID);
  if (rval >= 0) {
    return rval;
  }
#endif
  struct rusage usage;
  getrusage(RUSAGE_SELF, &usage);
  return
    tv_to_cycles(usage.ru_utime, MHz) + tv_to_cycles(usage.ru_stime, MHz);
}
