throttling is not changing

["Andreas Leppert" <wudmx-S0/GAf8tV78@public.gmane.org>]

hi,

sorry, i've posted firstly to the wrong list... hope this is the correct one!

i have a fujitsu amilo D 7830 laptop with a pentium 4 desktop with HT technology running gentoo linux with kernel 2.6.8.1. it doesn't matter if i enable or disable smp in the kernel config!

1) a pentium 4 (desktop, not mobile) has the throttling ability, correct?

2) does acpid works with smp enabled in the kernel?

3)
cat /proc/acpi/processor/CPU1/info
processor id: 0
acpi id: 1
bus mastering control: yes
power management: no
throttling control: yes
limit interface: yes

am i able to change the frequency (hint: /sys/device/system/cpu/cpu0/cpufreq/scaling_setspeed?)

4)
# cat /proc/acpi/processor/CPU1/throttling
state count: 8
active state: T1
states
T0: 00%
*T1: 12%
T2: 25%
T3: 37%
T4: 50%
T5: 62%
T6: 75%
T7: 87%

# echo -n 4 > /proc/acpi/processor/CPU1/throttling
# cat /proc/acpi/processor/CPU1/throttling
state count: 8
active state: T1
states
T0: 00%
*T1: 12%
T2: 25%
T3: 37%
T4: 50%
T5: 62%
T6: 75%
T7: 87%

nothing changes! thats my problem....

okay, here some information:
