Just installed FC5 on Intel core duo T2600 system (MSI 945GT Speedster motherboard).
Frequency scaling worked out of the box (cpuspped - style), but just for cpu0 (core 0). The other core (cpu1) runs all the time on the max clock frequency (2.16GHz), even with minimal system load.
Then stopped cpuspeed, tried ondemand:
service cpuspeed stop
modprobe cpufreq_ondemand
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
with the same result - CPU freq scaling works just for cpu0.
Last command gave "No such file or directory" error, so
I found out, that
/sys/devices/system/cpu/cpu1/cpufreq does not exist!
ls /sys/devices/system/cpu/cpu0/
cache cpufreq crash_notes topology
ls /sys/devices/system/cpu/cpu1/
cache crash_notes online topology
Any idea how to make this work?
Is it udev/sysfs issue?
