Description Brian Armstrong 2008-03-28 16:08:53 EDT
Description of problem:
Recently compiled kernels (kernel-2.6.24+) no longer contain the cpufreq 
modules necessary for controlling cpu speed on many Intell and AMD machines.
p4-clockmod
powernow-k6
powernow-k7
powernow-k8
speedstep-centrino
speedstep-ich
speedstep-lib
speedstep-smi

How reproducible:
modprobe [type one of the cpufreq modules]
modprobe p4-clockmod

Actual results:
FATAL:  Module p4_clockmod not found

Additional info:  Using a file manager to view the compiled kernel modules for 
the cpufreq shows all of the above mentioned modules as missing.
/lib/modules/2.6.24.3-50.fc8/kernel/arch/x86/kernel/cpu/cpufreq
/lib/modules/2.6.24.3-34.fc8/kernel/arch/x86/kernel/cpu/cpufreq
/lib/modules/2.6.24.3-12.fc8/kernel/arch/x86/kernel/cpu/cpufreq

Under the source code, look in the following sub-directory:  
arch/x86/kernel/cpu/cpufreq
Comment 1 Dave Jones 2008-03-28 16:21:15 EDT
p4-clockmod  : useless.

powernow-k6 : only present in the 586 kernel

powernow-k7 : non-modular, built-in
powernow-k8 : non-modular, built-in

speedstep-centrino: deprecated by acpi-cpufreq

speedstep-ich: non-modular, built-in
speedstep-lib: non-modular, built-in
speedstep-smi: non-modular, built-in
