conga Tech Notes
The conga-TCA3 has some technological features that require additional explanation. The following section will give the reader a better
understanding of some of these features.
7.1
Intel SoC Features
7.1.1
Intel Virtualization Technology
Intel
®
Virtualization Technology (Intel
®
VT) makes a single system appear as multiple independent systems to software. With this technology,
multiple, independent operating systems can run simultaneously on a single system. The technology components support virtualization of
platforms based on Intel architecture microprocessors and chipsets. Intel
®
Virtualization Technology for IA-32, Intel
®
64 and Intel
®
Architecture
(Intel
®
VT-x) added hardware support in the processor to improve the virtualization performance and robustness.
RTS Real-Time Hypervisor supports Intel VT and is verified on all current congatec x86 hardware.
Note
congatec supports RTS Hypervisor.
7.1.2
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-TCA3 ACPI thermal solution offers two different cooling policies.
•
Passive Cooling
When the temperature in the thermal zone must be reduced, the operating system can decrease the power consumption of the processor by
throttling the processor clock. One of the advantages of this cooling policy is that passive cooling devices (in this case the processor) do not
produce any noise. Use the “passive cooling trip point” setup node in the BIOS setup program to determine the temperature threshold that
the operating system will use to start or stop the passive cooling procedure.
