A feature we'll be adding to Solaris soon.
As for what determining what frequencies your processors are running at, you can find that out from the cpu_info kstat. $ kstat -m cpu_info -s current_clock_Hz module: cpu_info instance: 0 name: cpu_info0 class: misc current_clock_Hz 2800000000 module: cpu_info instance: 1 name: cpu_info1 class: misc current_clock_Hz 2800000000 Supported frequencies can be found using the cpu_info kstat too: $ kstat -m cpu_info -s supported_frequencies_Hz module: cpu_info instance: 0 name: cpu_info0 class: misc supported_frequencies_Hz 2800000000:3200000000 module: cpu_info instance: 1 name: cpu_info1 class: misc supported_frequencies_Hz 2800000000:3200000000 Mark _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
