Bug#278442: RFH: athcool -- Enable powersaving mode for Athlon/Duron processors
I request assistance with maintaining the athcool package.
The package description is:
athcool is a small utility for enabling/disabling Powersaving mode
for AMD Athlon/Duron processors.
By enabling Powersaving mode you can lower power consumption and
CPU temperature when the CPU is idle.
Powersaving works only if your kernel supports ACPI (APM does not
work), because athcool does only (un)set the "Disconnect enable when
STPGNT detected" bits in the Chipset's Northbridge. To really save
power, the STPGNT signal has to be sent when the CPU is idling. This
is done by the ACPI subsystem when C2 state entered.
Depending on your motherboard and/or hardware components, enabling
Athlon powersaving mode sometimes causes:
* noisy or distorted sound playback,
* a slowdown in harddisk performance,
* system locks or instability,
* massive corruption of the filesystem (observed at least once).
If you met those problems, you should not use athcool. Please use
athcool AT YOUR OWN RISK.
If athcool works fine for you, and you want it to run automatically
on startup, please read the /usr/share/doc/athcool/README.Debian
Unfortunately, I only own one athlon-based system, which means I'm
unable to test athcool on most supported systems. Hence, I'd like some
volunteers to test athcool on as many different systems as possible, and
to try to reproduce the bugs that are reported. If you own an
athlon-based computer and want to help me with athcool, please send me
an e-mail and tell me what kind of motherboard/CPU you own.
FYI, I currently need someone with a VIA KT600 or KT400 chipset to try
to reproduce bug #276757 on both kind of systems.
Thanks in advance,
