Needed for the HZ macro.
Reading why this would be needed, diving into libgtop. This is basically
for reading the rtime field of glibtop_proc_time which is filled on
linux by reading from /proc/stat
/* clock_t (1/100 s) */
buf->utime = strtoull (p, &p, 0);
buf->stime = strtoull (p, &p, 0);
buf->rtime = buf->utime + buf->stime;
So seemingly non-normalized values
but on freebsd with
pinfo = kvm_getprocs (server->machine.kd, KERN_PROC_PID, pid, &count);
if ((pinfo == NULL) || (count != 1)) {
glibtop_warn_io_r (server, "kvm_getprocs (%d)", pid);
glibtop_suid_leave (server);
return;
}
glibtop_suid_leave (server);
buf->rtime = pinfo [0].ki_runtime * 1e-6;
len = sizeof (ci);
if (sysctlbyname ("kern.clockrate", &ci, &len, NULL, 0)) {
glibtop_warn_io_r (server, "sysctl (kern.clockrate) (%d)", pid);
glibtop_suid_leave (server);
return;
}
buf->frequency = (ci.stathz ? ci.stathz : ci.hz);
buf->flags = _glibtop_sysdeps_proc_time;
buf->rtime *= buf->frequency;
where kvm_getprocs is, according to [0], returning the value in
microsecs which is then normalized away with * 1e-6 and then again
multiplied by sysctl kernel.clockrate field stathz
kern.clockrate: { hz = 1000, tick = 1000, profhz = 8128, stathz = 127 }
so 127.
Please everyone recheck my math here, it's nearly 1 am in the morning
here ;-)
