I think it could work for UltraSPARC-IIe, but not for UltraSPARC-III as frequency has to be independently set for each couple schizo/cpu. To modify energy_star register (in schizo), I have to access to energy_star register associated to the corresponding CPU. In another hand, I don't understand why cpufreq interface is registered once for the system and not by CPU. If it was registered by cpu, it will be easier to use cf_cookie. Regards, JKB
