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 -------------- next part -------------- An HTML attachment was scrubbed...
