Description larse 2001-05-25 00:30:07 UTC 
The machdep.tsc_freq sysctl knob does not exists on systems that have
power management (APM) or SMP enabled. It's the easiest way to query
for probed CPU speed.

The patch below adds a new read-only sysctl know "hw.cpuhz" which is
initialized from tsc_freq at boot time. Since it's read-only, it is
ok to use on SMP and APM-enabled machines.

Please transmogrify the patch as needed for inclusion in the tree.
