Hello all,
We recently had Intel give our company a roadmap presentation where they
told us that their enhanced speedstep technology was supported by linux
kernels 2.6.9+. I have since tried to get cpufreq speedstep driver to
work with no luck on our em64t Xeon 3.6g processors. Intel even has a
webpage describing the technology and how to get it working at url:
http://www.intel.com/cd/ids/developer/asmo-na/eng/195910.htm?prn=Y
I made a bugzilla report to redhat [Bug 169290] and got a reply that
none of the Xeon's were supported yet on speedstep because they cannot
find documentation detailing the tables of frequencies these CPUs support.
The only processor I have had luck with so far is a 32-bit Xeon with the
p4-clockmod driver(which does not appear to be present in the x86-64
kernel).
Anyone have any knowledge regarding cpufreq and when the em64t's are
going have a linux driver supporting the speedstep technology? If it is
an issue of Intel not providing the neccessary info, maybe I can press
the issue with the gentlemen that came to my office and stated support
was there already.
Thanks for any info and advice. Please CC my on any replies since I am
not on the list.
