I want to bring up this topic again. It would be nice to get PowerNow/Cool?'n'Quite working.

cpuspeed ( seems to work only on Intel systems and not AMD: "CPU0 Error get throttling rc=65283"

The source is not available but I also haven't tried to contact the author yet.

I currently busy working on SWTSwing or better Java applications using SWT to make them work with SWTSwing (e.g. Azureus, Eclipse,...) instead of SWT.

Here is the linux code to start with...

AMD Turion™ 64 Mobile Technology, AMD Opteron™ Processors, and AMD Athlon™ 64 Processors Driver Version 1.60.01 for Linux 2.6. - Supports all AMD Turion™ 64 Mobile Technology, AMD Opteron™ Processors, and Athlon™ 64 Processors released through 2006. Provides support for AMD PowerNow?!™ technology and, where appropriate, AMD’s Cool-n-Quiet™ technology for Linux systems. Works with all kernels, version 2.6.10 or later. Requires cpufreq-1.20, cpuspeed-1.20.1, or powersaved-0.8.19 or later to support SMP and dual-core systems.

Adding hook for external drivers to Power State and Throttling. acpi.psd can't support realization of PowerNow?! in ACPI tree, because this methods using "OEM access to HW"
