Hi,

I am using kernel 2.5.55 on a Sony Vaio PCG-FXA49. Right now,
/proc/acpi/processor/CPU0/info says that performance management is
not available. My CPU (1.2 GHz mobile Athlon4) supports PowerNow, and
I would expect this would qualify as performance management.

I have looked at my ACPI tables and there is a listing of 5 P-states
in my SSDT (1200 MHz,1000,800,600,500 MHz).

Why are these not listed in my /proc/acpi/processor/CPU0 directory?

Does the current Linux ACPI driver look at the SSDT tables, or does it
only look at the DSDT for AML?

One thing to note is that my DSDT has a very minimal \_PR section:

    Scope (\_PR)
    {
        Processor (CPU0, 0x01, 0x00008010, 0x06) {}
    }

The SSDT has a more filled out one. I do not know how to disassemble
it (iasl does not know how to handle a SSDT).

-Nathan
