Powertweak-Linux is a tool to tune your system to its optimal performance settings. It started life as the replacement for the now obsolete kernel option 'tune PCI bridges', and has been extended to provide more features and support more chipsets.

It can also tune network/filesystem performance using /proc/sys entries, disk elevator settings, and x86 CPU registers (needs 2.2.18 or 2.4.0test kernel), CDROM speeds, hdparm type features, and Sony VAIO backlight. It has both a GTK GUI and a text-based lister.

Here are some key features of "Powertweak Linux":
DMI BIOS interrogation (not only bios settings, but ports, cpu and events) (NEW)
some 2.5 linux kernel proc settings (NEW)
PCI configuration space tuning.
Adjusting block device elevator algorithms.
Changing /proc/sys entries.
hdparm type features (Informational only right now)
IDE SMART status.
CPU Model specific register tuning
CPU MTRR registers (Informational only right now)

What's New in This Release:
Architectural changes:

Core plugins.
Plugins can now be written to have dependancies on others that get loaded first.
PCILIB converted to core.
PCI backend got split up to take advantage of core.
Socket communication moved to libpowertweak removing duplication.

New Features:

BIOS DMI backend.
Now writes status messages to /var/log/powertweak.log - new simple text mode read only client (lspowertweak)

Bugfixes

GTK UI tooltips now work correctly.
Pentium III XML fixed.
Various bulletproofing found with valgrind and similar tools.
