DCA Prefetch Delay
A DCA Prefetcher is used with a TOE (TCP/IP Offload Engine) adapter to prefetch
data in order to shorten execution cycles and maximize data processing efficiency.
Prefetching data too frequently can saturate the cache directory and delay neces-
sary cache access. This feature reduces or increases the frequency the system
prefetches data. The options are [8], [16], [24],
[32]
, [40], [48], [56], [64], [72], [80],
[88], [96], [104], [112].
X2 APIC (Advanced Programmable Interrupt Controller)
Based on Intel's Hyper-Threading architecture, each logical processor (thread) is
assigned 256 APIC IDs (APIDs) in 8-bit bandwidth. When this feature is set to En-
able, the APIC ID will be expanded from 8 bits (X2) to 16 bits to provide 512 APIDs
to each thread to enhance CPU performance. The options are
Disable
and Enable.
AES-NI
Select Enable to use the Intel Advanced Encryption Standard (AES) New Instruc-
tions (NI) to ensure data security. The options are Enable and
Disable
.
Intel Virtualization Technology
Select Enable to use Intel Virtualization Technology support for Direct I/O VT-d sup-
port
by reporting the I/O device assignments to the VMM (Virtual Machine Monitor)
through the DMAR ACPI tables. This feature offers fully-protected I/O resource
sharing across Intel platforms, providing greater reliability, security and availability
in networking and data-sharing. The options are
Enable
and Disable.
