| Hi, people !
|
| With default debian linux-image and initrd, even kernel is named
| bla-bla-k8, powernow-k8 subsystem isn't compiled, but is as module,
| thus there's no /sys/power interface for powersaving. If i'm trying to
| load modules by hand i 'm getting this:
|
| deen:/home/olecom#
| deen:/home/olecom# modprobe acpi-cpufreq
| FATAL: Error inserting acpi_cpufreq
| (/lib/modules/2.6.16-2-amd64-k8/kernel/arch/x86_64/kernel/cpufreq/acpi-cpuf
|req.ko): No such device
| deen:/home/olecom#
| deen:/home/olecom# modprobe powernow-k8
| deen:/home/olecom# modprobe acpi-cpufreq
| FATAL: Error inserting acpi_cpufreq
| (/lib/modules/2.6.16-2-amd64-k8/kernel/arch/x86_64/kernel/cpufreq/acpi-cpuf
|req.ko): Device or resource busy
| deen:/home/olecom#
|
| But it certainly works, if compiled in. I have no clue what to do.
| Maybe this is bug in linux ?
No, it is not. Modprobing powernow-k8 is enough to get speedstep support for
your cpu.
You should then run "sudo modprobe cpufreq_performance cpufreq_powersave
cpufreq_stats" and install powernowd daemon.
Good luck ;)
