Hi,
up to 2.6.15 my kernel worked to find my processor and frequency scalling was
possible via cpufreq. I have
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Intel(R) Celeron(R) CPU 2.40GHz
stepping : 9
cpu MHz : 2398.803
cache size : 128 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 apic sep mtrr pge mca
cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid xtpr
bogomips : 4801.41
Now it is screwed up...
My config:
│ │ [*] CPU Frequency scaling
│ │
│ │ [ ] Enable CPUfreq debugging
│ │
│ │ <*> CPU frequency translation statistics
│ │
│ │ [*] CPU frequency translation statistics details
│ │
│ │ Default CPUFreq governor (userspace) --->
│ │
│ │ <*> 'performance' governor
│ │
│ │ <*> 'powersave' governor
│ │
│ │ --- 'userspace' governor for userspace frequency scaling
│ │
│ │ <*> 'ondemand' cpufreq policy governor
│ │
│ │ <*> 'conservative' cpufreq governor

Thanks for fixing

are you sure it was frequency scaling and not throttling? I thought real
frequency scaling was only available on non-Celeron processors.....
(and throttling isn't all that great for power save)

Hi,
I am totally sure. It was cpufreq via normal P4/XEON - trottling doesn't work
for me:
notas:/usr/src/linux-2.6.16# cat /proc/acpi/processor/CPU0/throttling
<not supported>

Hi Arjan,
here you can see my laptop configured by anyone else which also has cpufreq
enabled and working:

...is using p4-clockmod which is basically useless for power saving
It does the same as throttling IIUC.

Hi Stefan,
yes, it is clockmod, but problem is, that my laptop doesn't support
throttling, so this is only chance for me to do scaling...
cat /proc/acpi/processor/CPU0/throttling
<not supported>
Regards
Michal
