VIA C3™ Processor Power
Saver Feature
| This
document describes the necessary steps to activate the Power
Saver feature (previously known as Longhaul) for VIA C3
processors, thereby making it possible to dynamically adjust
the processor clock frequency according to system workload.
The Power Saver feature is considered experimental at this
time. |
Nehemiah Hardware Random Number
Generator Linux Driver & Test Utility Usage
Guide
| The VIA C3 Nehemiah processor includes a
high-performance hardware-based random number generator (RNG)
on the processor die. The kernel starts to have a driver
supporting the RNG from version 2.5.65. This document
describes how to update the kernel and then make use of the
RNG. We also offer a test utility with source code for users’
immediate evaluation.

Hardware
Monitor
| These guides show how to install the LM_Sensors package
to enable the hardware monitoring functions for VIA
southbridge chips VT82C686B and VT8231, and Low-Pin-Count
Super I/O chip VT1211 that integrate a hardware monitor
controller. The LM_Sensors package includes necessary hardware
monitor and SMBus drivers for other utilities to acquire
system-wide PC health information such as voltage,
temperature, and fan speed. For systems using VIA south bridge
chips but with other vendors’ hardware monitor chips, we
provide a sample program for reading data via the SMBus to
facilitate users’ test and development.

Printer Driver Installation
Guide
| This guide provides information about printer driver
installation covering printers using parallel or USB port for
VIA’s southbridge chips VT82C686B, VT8231, and VT8233 under
Red Flag Linux 3.0. The XW tools supports various printer
types and thus is recommended. For testing purposes, we print
different file formats including word, text, image (.jpg or
.gif), Excel, and PDF using the office application Star Suite
6.0. |
