Atom CPU

Does the Intel ATOM cpu come with frequency scaling? I was not sure so when I built my kernel I omitted any kinda of processor scaling. If so what processor do you select in the kernel configuration?

I haven't spotted any particularly clear answers yet, but a bit of searching turned up this and this. Now, it may depend on which version of the Atom processor you have, but it appears that using generic settings is best for now.

IE, in Power Management... --> CPU Frequency scaling --> ACPI Processor P-States driver (CONFIG_X86_ACPI_CPUFREQ)

And Pentium-Pro as the processor family.

Of course, you could also enable all the (or all the Intel) frequency scaling options as modules.
