Subject: RE: DBS enabling on EM64T machine with cpufreqd
Date: Thu, 26 May 2005 06:15:07 -0700 [thread overview]
Message-ID: <88056F38E9E48644A0F562A38C64FB6004D356D0@scsmsx403.amr.corp.intel.com> (raw)
For Nocona I would suggest using the in kernel ondemand governor. More
details here
http://www.intel.com/cd/ids/developer/asmo-na/eng/dc/xeon/reference/1959
10.htm
And newer versions of the userspace governors should be able to handle
SMP processsors. Earlier versions didn't. Not sure which version of
cpufreqd you are using.
Thanks,
Venki
