VIA C7-M PowerSaver, Speedstep/Throttling

[eco]

From: Brett Carlock

Does the eComStation ACPI/APM driver support the VIA C7-M PowerSaver so that the processer can change frequencies? I know that you can throttle Intel & AMD CPUs, right? I ask because I want to install eComStation on my Sylvania G Netbook (Everex Cloudbook) but can't get eCS to install from USB. If I can, I would like to help get the hardware supported by eComStation.

Usially, only add in own acpi table throttling and powersaving, attach here acpi.log, pls

e-co:

The hardware is not available.

From using the GetSetState tool, it looks like it can read the throttle states of the VIA C7-M correctly, but it appears to be locked at 1.6ghz (state 0).

Logs are attached here.

This ticket is extremely old and for an unsupported version. Please try the current version.

Running acpistat will tell you if throttling is supported on your system. It will also tell you if Performance Control (Speedstep) is supported.

No response. Very old ticket. Throttling and Performance Control is assumed not supported on this machine.
