It is running ubuntu so its essentialy a 2.6.10 kernel. Scaling the frequency dynamically works very good so far, i can choose between ~500mhz and ~600mhz. However, when i boot into windows xp sp2, after installing some enabler programm from the compaq website, the freqency of the cpu is scaled dynamically with the THREE steps ~413mhz, ~500mhz and ~600mhz, the exact values for 500 and 600 being the same as in linux. So in windows i get an extra frequency option for 413mhz not available in linux. Is there any chance of supporting this in linux? Since i only ever heard of 2 frequency steps for the early p3's, i think this will be a compaq-specific behaviour. Is compaq giving out documentation? please cc me Greetings Simon Braunschmidt simon@heimdal:/sys/devices/system/cpu/cpu0/cpufreq$ uname -a Linux heimdal 2.6.10-5-686 #1 Tue Apr 5 12:27:02 UTC 2005 i686 GNU/Linux simon@heimdal:/sys/devices/system/cpu/cpu0/cpufreq$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 8 model name : Pentium III (Coppermine) stepping : 3 cpu MHz : 498.115 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse bogomips : 986.45 simon@heimdal:/sys/devices/system/cpu/cpu0/cpufreq$ sudo cat * Password: 0 500000 600000 500000 600000 500000 userspace ondemand powersave performance 500000 speedstep-smi userspace 600000 500000 500000 simon@heimdal:/sys/devices/system/cpu/cpu0/cpufreq$
