I am working on a 2.4.22-kernel (from kernel.org) and patched the=20 patch-2.4.22-ac4.bz2 from Alan Cox against it. Because of having a low battery-capacity I tried to enable cpufreq and=20 ACPI-stuff in the kernel (and tried to compile them as modules as well). If I then boot the machine, I tried the following: $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 8 model name : Pentium III (Coppermine) stepping : 6 cpu MHz : 1000.916 cache size : 256 KB physical id : 0 siblings : 1 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 apic sep mtrr pge=20 mca cmov pat pse36 mmx fxsr sse bogomips : 1998.84 $ cat /proc/cpufreq minimum CPU frequency - maximum CPU frequency - policy root:/usr/src/linux-2.4.22# insmod speedstep-ich Using /lib/modules/2.4.22-ac4-486/kernel/arch/i386/kernel/speedstep-ich.o /lib/modules/2.4.22-ac4-486/kernel/arch/i386/kernel/speedstep-ich.o:=20 unresolved symbol speedstep_get_processor_frequency /lib/modules/2.4.22-ac4-486/kernel/arch/i386/kernel/speedstep-ich.o:=20 unresolved symbol speedstep_detect_processor /lib/modules/2.4.22-ac4-486/kernel/arch/i386/kernel/speedstep-ich.o:=20 unresolved symbol speedstep_get_freqs and didn't saw any real frequencies. At the moment I don't know if my cpu could handle cpufreq-controlling at=20 all, but hope it. I searched the archive of this ml, but except of=20 "Coppermines might cause problems, might not work..." I can't find=20 helpful things. Thanks a lot and if there is something you need to help get it running,=20 or I should do or try, please tell me. (Well I tried to understand the=20 stuff in Documentation/cpu-freq, but...;)) Best regards, Matthias --=20 Freundliche Gr=FC=DFe, ### http://www.stop1984.com Matthias Hannich ### nulli@stop1984.com ### KeyID: 407A2F69 Fingerprint: 600D 7E07 105C F674 0C4B 12C2 4DE4 A8DF 407A 2F69
