3.13 System Management
3.13.1 Intel
®
Hyper-Threading Technology
(Note: The following information is from Intel® document No. 328901,
“Mobile 4th Generation Intel® Core™ Processor Family Datasheet –
Volume 1
of 2”, Rev: 002; September, 2013.
)
The processor supports Intel® Hyper-Threading Technology (Intel® HT
Technology) that allows an execution core to function as two logical
processors. While some execution resources such as caches, execution units,
and buses are shared, each logical processor has its own architectural state
with its own set of general-purpose registers and control registers. This
feature must be enabled using the BIOS and requires operating system
support.
The Intel® HT Technology is enabled by default; no action by the operator is
required.
For further information on disabling support for this technology, refer to
The
APTIO Haswell Core BIOS Manual For Acromag Products.
3.13.2 Enhanced Intel
®
SpeedStep Technology (EIST)
The Enhanced Intel
®
SpeedStep Technology (EIST) used by this processor
enables very high performance while also meeting power-conservation
needs. When EIST is enabled, the clock frequency of the CPU is dynamically
changed in response to the CPU load
The Intel
®
SpeedStep feature is enabled by default. For further information on
disabling support for this technology, refer to
The APTIO Haswell Core BIOS
Manual For Acromag Products.
3.13.3 Intel
®
Virtualization Technology (Intel VT-x and VT-d)
Intel
®
Virtualization Technology (Intel VT) makes a single system appear as
multiple independent systems to software. This allows for multiple,
independent operating systems to be running simultaneously on a single
system. Intel VT comprises technology components to support virtualization
of platforms based on Intel architecture microprocessors and chipsets. The
first revision of this technology (Intel VT-x) added hardware support in the
processor to improve the virtualization performance and robustness. The
second revision of this specification (Intel VT-d) adds chipset hardware
implementation to improve I/O performance and robustness.
The Intel
®
VT‐x
and VT-d features are enabled by default. For further
information on disabling support for this technology, refer to
The APTIO
Haswell Core BIOS Manual For Acromag Products.
