I've been searching Google and haven't seen this problem mentioned
since the 2.5.x days, and haven't found anything apparent in the code
or docs about it.
In short, CONFIG_CPU_FREQ is on, but nothing shows up under
/sys/devices/system/cpu/cpu0/.
Kernel is vanilla 2.6.12.3 built with gcc-3.3.6.
Hardware is "PIII (Coppermine) stepping 03" with a 440BX, details below.
Relevant /proc/config.gz entries below too; (SMI, no modules).
"dmesg | fgrep -i freq" comes up empty.
ACPI succeeds in setting the frequency, in eight steps.
Must one-or-other bit be in a module? What am I doing wrong?
(And, would it be OK to make them modules if I'm not using initrd?)
With debug=2, dmesg says only:
speedstep-lib: x86: 6, model: 8
speedstep-lib: Coppermine: MSR_IA32_EBL_CR_POWERON is 0x45080020, 0x0
speedstep-lib: Coppermine: MSR_IA32_PLATFORM ID is 0x0, 0x23570000
speedstep-smi: signature:0x00008680, command:0x0000e6f5, event:0x00000000, perf_level:0x47534943.
and
acpi-cpufreq: acpi_cpufreq_init
acpi-cpufreq: acpi_cpufreq_cpu_init
acpi-cpufreq: acpi_processor_cpu_init_pdc
Thanks,

Following up (Coppermine/440BX) ...
I tried booting with cpufreq.debug=3. With CONFIG_X86_ACPI_CPUFREQ
enabled, I watched it try, and fail, to register:
CPU: After all inits, caps: 0383f9ff 00000000 00000000 00000040
00000000 00000000 00000000
[...]
ACPI: CPU0 (power states: C1[C1] C2[C2])
ACPI: Processor [C0D5] (supports 8 throttling states)
[...]
acpi-cpufreq: acpi_cpufreq_init
cpufreq-core: trying to register driver acpi-cpufreq
cpufreq-core: adding CPU 0
acpi-cpufreq: acpi_cpufreq_cpu_init
acpi-cpufreq: acpi_processor_cpu_init_pdc
cpufreq-core: initialization failed
cpufreq-core: no CPU initialized for driver acpi-cpufreq
cpufreq-core: unregistering CPU 0
... with nothing from the SMI driver. With CONFIG_X86_SPEEDSTEP_SMI
the only cpufreq driver, and with or without "smi_cmd=0x82 smi_port=0xb2
smi_sig=1", I saw no reports about cpufreq at all; just the same
speedstep-lib and speedstep-smi initialization lines quoted below.
The BIOS only offers choices of boot media. Ideas, please?
Is this supposed to work, or am I out on the ragged edge?

Im having similar problems also using coppermine with 440BX chipset,
acpi-freq doesnt work, and smi seems to load but doesnt find supported
freqs ;(
I hoppe someone knows what is happening with coppermines...
