Re: [suse-laptop] Re: Dell Latitude C600 PIII-Coppermine SpeedStep && APM?
Hello all, I have now tried almost everything it seems -- it still won't scale. I cannot set the speed up and down with powersave -l or -f, respectively or dynamically with -A. Afa I can say only the BIOS settings have an effect on the CPU speed (either fixed to 850 or 700, or somewhat "dynamic": 850 when plugged in after reboot or suspend, and 700 w/o AC...) Are those settings owerwritten by any OS or only by ACPI OSs? At least partially? Or don't those settings matter at all once the OS supports and knows how to speedstep? And now the ugly question: where to does syslogd write its output? The things I changed according to your advice: /etc/sysconfig/powersave/common ## Path: System/Powermanagement/Powersave/General ## Type: string ## Default: "" # *************************************** POWERSAVE_CPUFREQD_MODULE="speedstep-smi" # *************************************** ## Path: System/Powermanagement/Powersave/General ## Type: string ## Default "" # *************************************** #POWERSAVE_CPUFREQD_MODULE_OPTS="speedstep_coppermine=1" POWERSAVE_CPUFREQD_MODULE_OPTS="" # *************************************** The latter option (now commented, but tried on my own) gives an error that speedstep_c... is unknown to speedstep_smi. /etc/modprobe.conf.local # # please add local extensions to this file # options speedstep-lib relaxed_check=1 In _both_ cases /var/log/messages gives me: Dec 26 10:29:13 dionysos kernel: cpufreq: change failed with new_state 1 and result 0 Dec 26 10:29:13 dionysos kernel: cpufreq: change failed with new_state 1 and result 2 Without the explicit module in common it says something like the chipset is not supported :( The symptoms stay the same, too, of course. /proc/cpuinfo is a little different though, here I get a higher CPU speed but that's due to a different BIOS setting! dionysos:~ # powersave -c Speed stepping is not supported. dionysos:~ # cat /proc/cpufreq minimum CPU frequency - maximum CPU frequency - policy (apparently the system does not know anything about available freqs...?!) dionysos:~ # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 8 model name : Pentium III (Coppermine) stepping : 6 cpu MHz : 851.993 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 patpse36 mmx fxsr sse bogomips : 1683.45 HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
