Default Nvidia nForce 680i DSDT

I'm trying to fix the DSDT of my DFI Lanparty UT NF680i motherboard, which misses support for processor C-states (power) and T-states (throttling).

Does anybody have a nForce 680i-based motherboard with working C-states and/or T-states and can share their DSDT?

to check for working C-states you can:

cat /proc/acpi/processor/CPU0/power

(if there's anything below "states:")

to check for working T-states you can:

cat /proc/acpi/processor/CPU0/throttling

(if there's anything below "states:")

DSDT contents are available in /proc/acpi/dsdt.

Default Re: Nvidia nForce 680i DSDT

Before you try too hard looking at the DSDT, does your BIOS export any
SSDT tables? It may very well be that the _CST object is hidden in one
of the SSDTs. If there are no _CST objects then this is clearly a BIOS bug
and you should bug DFI about that. Otherwise I suggest you file a bugreport
against the ACPI subsystem at http://bugzilla.kernel.org.
