speedstep and powernow work fine under linux, but usually require a kernel that knows about your sepecific cpu. Auto-detection isn't fully baked, and I have to load the appropriate modules, but it works fine after that. in my case: * cpufreq_userspace * powernow-k8 On my X2 I get 4 speed choices and both cores need to run the same speed: pmg-alliance:10002:/sys/devices/system/cpu/cpu0/cpufreq/ cat scaling_available_frequencies 2200000 2000000 1800000 1000000 pmg-alliance:10003:/sys/devices/system/cpu/cpu0/cpufreq/ cat scaling_cur_freq 1000000 pmg-alliance:10004:/sys/devices/system/cpu/cpu0/cpufreq/ cat affected_cpus 0 1 I'd recomend powernowd (v0.97) using the userspace governor, but there are other choices out there. -- Dave _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
