Intel

VT is a multi-generational series of extensions to Intel
®
processor and platform architecture that provides a new hardware foundation for
virtualization, establishing a common infrastructure for all classes of Intel
®
based systems. The broad availability of Intel
®
VT makes it possible
to create entirely new applications for virtualization in servers, clients as well as embedded systems thus providing new ways to improve system
reliability, manageability, security, and real-time quality of service.
The success of any new hardware architecture is highly dependent on the system software that puts its new features to use. In the case of
virtualization technology, that support comes from the virtual machine monitor (VMM), a layer of software that controls the underlying physical
platform resources sharing them between multiple “guest” operating systems. Intel
®
VT is already incorporated into most commercial and
open-source VMMs including those from VMware, Microsoft, XenSource, Parallels, Virtual Iron, Jaluna and TenAsys.

Note
congatec does not offer virtual machine monitor (VMM) software. All VMM software support questions and queries should be directed to the
VMM software vendor and not congatec technical support.

Thermal Management
ACPI is responsible for allowing the operating system to play an important part in the system’s thermal management. This results in the
operating system having the ability to take control of the operating environment by implementing cooling decisions according to the demands
put on the CPU by the application.
The conga-TC175 supports Critical Trip Point. This cooling policy ensures that the operating system shuts down properly if the temperature in
the thermal zone reaches a critical point, in order to prevent damage to the system as a result of high temperatures. Use the “critical trip point”
setup node in the BIOS setup program to determine the temperature threshold that the operating system will use to shut down the system.
For processor passive cooling, use the Thermal Control Circuit (TCC ) Activation Offset setting in the CPU configuration setup sub menu. The
TCC in the processor is activated at 100°C by default but can be lowered by the Activation Offset e.g., setting 10 activates TCC at 90°C. ACPI
OS support is not required.
Note
The end user must determine the cooling preferences for the system by using the setup nodes in the BIOS setup program to establish the
appropriate trip points.
