Hi,

I was reading through cpufreq(4) and in the bugs section it mentions that p=
er=20
core (or CPU) frequency control is not supported.  That all cores/CPUs have=
 to=20
be at the same speed. =20

What is the reason for that? =20

Is it an infrastructure problem with FreeBSD or has it just not been=20
implemented? =20

And how will the recent work on event timers (and a "tickless" kernel) impa=
ct=20
on this problem?=20

Regards,

David
