I see in the archives that there was little functionality in this are as of 2004, and then substantial work in 2005 to make cpufreq available through sysctl. At that time there is a thread indicating how nice it would be if someone wrote a daemon to do the control for this a la cpufreqd http://lists.freebsd.org/mailman/htdig/freebsd-amd64/2005-February/003524.html I cannot seem to find anything relating to throttling and or AMD Cool&Quiet after that point. Is there such a daemon? Thanks for any pointers, Andrew.
