Intel(R) VT for Directed
I/O
Enabled
Disabled
Enable/Disable Intel
®
Virtualization Technology
for Directed I/O (Intel
®
VT-
d).
Report the I/O device
assignment to VMM
through DMAR ACPI
Tables.
This option is only visible if all
processors installed in the system
support Intel
®
VT-d. The software
configuration installed on the system
must support this feature in order for
it to be enabled.
Interrupt Remapping
Enabled
Disabled
Enable/Disable Intel
®
VT-d
Interrupt Remapping
support. For some
processors, this option
may be "always enabled".
This option only appears when Intel
®
Virtualization Technology for
Directed I/O is Enabled. For some
processors this will be enabled
unconditionally whenever Intel
®
VT-d
is enabled. In this case, this option
will be shown as "Enabled", and
grayed out and not changeable.
Coherency Support
Enabled
Disabled
Enable/Disable Intel
®
VT-d
Coherency support.
This option only appears when Intel
®
Virtualization Technology for
Directed I/O is Enabled.
ATS Support
Enabled
Disabled
Enable/Disable Intel
®
VT-d
Address Translation
Services (ATS) support.
This option only appears when Intel
®
Virtualization Technology for
Directed I/O is Enabled.
Pass-through DMA
Support
Enabled
Disabled
Enable/Disable Intel
®
VT-d
Pass-through DMA
support. For some
processors, this option
may be "always enabled".
This option only appears when Intel

data coming from memory
will be poisoned. If
disabled (default), will be in
Legacy Mode – No data
poisoning support
available.
Enhanced Error Containment (Data
Poisoning) is not supported by all
models of processors, and this
option will not appear unless all
installed processors support
Enhanced Error Containment. This
option globally enables or disables
both Core and Uncore Data
Poisoning.
MLC Streamer
Enabled
Disabled
MLC Streamer is a
speculative prefetch unit
within the processor(s).
Note: Modifying this
setting may affect
performance.
MLC Streamer is normally Enabled,
for best efficiency in L2 Cache and
Memory Channel use but disabling it
may improve performance for some
processing loads and on certain
benchmarks.
MLC Spatial Prefetcher
Enabled
Disabled
[Enabled] – Fetches
adjacent cache line (128
bytes) when required data
is not currently in cache.
[Disabled] – Only fetches
cache line with data
required by the processor
(64 bytes).
MLC Spatial Prefetcher is normally
Enabled, for best efficiency in L2
Cache and Memory Channel use but
disabling it may improve
performance for some processing
loads and on certain benchmarks.
