Subjectcpufreq and p4 prescott
Hi,

i have problems scaling down my p4 prescott 2.8 GHz.
In the /sys -tree all seems to be ok:

[ck@holodeck:cpufreq] pwd
/sys/devices/system/cpu/cpu0/cpufreq

[ck@holodeck:cpufreq] ls -1
cpuinfo_max_freq
cpuinfo_min_freq
scaling_available_frequencies
scaling_available_governors
scaling_driver
scaling_governor
scaling_max_freq
scaling_min_freq
scaling_setspeed

[ck@holodeck:cpufreq] cat *
2800000
350000
350000 700000 1050000 1400000 1750000 2100000 2450000 2800000
powersave userspace performance
p4-clockmod
userspace
2800000
350000
350000

[ck@holodeck:cpufreq] cat /proc/cpuinfo | grep Mhz
cpu MHz : 2807.131
cpu MHz : 2807.131

As you can see tools like cpudyn or powernowd successfully
change the entry in scaling_setspeed (also for cpu1),
but the real cpu clock stays at 2.8GHz ?

The cpudyn doc sais there's support for 'Intel Pentium 4, Intel Xeon'
CPU's, but is there support for p4 prescott ?

Has annyone here successfully scaled down a prescott ?

regards,
clee
