There does not exist the "cpufreq" directory. The following command
# modprobe cpufreq_ondemand
can be executed and nothing is output. However, still no "cpufreq" directory
is created in /sys/devices/system/cpu/cpu0/ after the command is done.
BTW, I don't know where can I check whether the hardware is supporting
the CPUfreq. I just learn from maillist if someone want to check the cpufreq
support in hardware he can run the following commands to do checking:
# grep est /proc/cpuinfo
Any helps?
Thanks agin,
Ian
