For now, you'll only ever see a dev.cpu.0.freq and changes to it will be made to all processors. (I'm still improving MP support but that's how it will be.) In the future, once the hardware drivers are improved to support independent MP frequencies, the framework can easily be updated to export the sysctls on all cpus. This change is about 10 lines of code. Info about the framework is in the cpufreq(4) man page. The acpi projects page is where work is currently being noted. I haven't updated it recently though but once I get the next round of commits in, I will. -- Nate
