Can someone please help me figure out if xeon.sfbay can be used for 
studying how DVFS works? The site  
http://blogs.sun.com/mhaywood/entry/introducing_speedstep_on_solaris 
suggests that Intel Xeon is capable of supporting several frequencies. 
However, when I run "kstat -m cpu_info -s supported_frequencies_Hz", I 
get the following:

module: cpu_info                        instance: 0
name:   cpu_info0                       class:    misc
       supported_frequencies_Hz        1793370470

module: cpu_info                        instance: 1
name:   cpu_info1                       class:    misc
       supported_frequencies_Hz        1793370470

module: cpu_info                        instance: 2
name:   cpu_info2                       class:    misc
       supported_frequencies_Hz        1793370470

module: cpu_info                        instance: 3
name:   cpu_info3                       class:    misc
       supported_frequencies_Hz        1793370470

which suggests that only one frequency is supported. The kernel version 
is: SunOS 5.11 snv_79. Is it possible that a later version of Nevada is 
required for DVFS?

Thanks,

David
