XPT Remote Prefetch
Select Enable to support XPT (Extended Prediction Table) Remote Prefetch which will
allow an LLC request to be duplicated and sent to an appropriate memory controller in a
remote machine based on the recent LLC history to reduce latency. The options are Enable,
Disable, and
Auto .
KTI Prefetch
Select Enable for the KTI prefetcher to preload the L1 cache with data deemed relevant
which will allow the memory read to start earlier on a DDR bus in an effort to reduce latency.
Select Auto for the KTI prefetcher to automatically preload the L1 cache with relevant data
whenever is needed. The options are
Auto
, Enable, and Disable.
Local/Remote Threshold
Use this feature to set the threshold for the Interrupt Request (IRQ) signals, which handle
hardware interruptions. The options are Disable,
Auto , Low, Medium, and High.
IO Directory Cache (IODC)
Select Enable for the IODC (I/O Directory Cache) to generate snoops instead of generating
memory lockups for remote IIO (InvIToM) and/or WCiLF (Cores). Select Auto for the IODC to
generate snoops (instead of memory lockups) for WCiLF (Cores). The options are Disable,
Auto , Enable for Remote InvItoM Hybrid Push, InvItoM AllocFlow, Enable for Remote
InvItoM Hybrid AllocNonAlloc, and Enable for Remote InvItoM and Remote WCiLF.
SNC (Sub NUMA)
Select Enable to use "Sub NUMA Clustering" (SNC), which supports full SNC (2-cluster)
interleave and 1-way IMC interleave. Select Auto for 1-cluster or 2-cluster support depending
on the status of IMC (Integrated Memory Controller) Interleaving. The options are
Disable
and Enable SNC2 (2-clusters).
XPT Prefetch
Select Enable to support XPT (Extended Prediction Table) Prefetch which will allow an LLC
request to be duplicated and sent to an appropriate memory controller based on the recent
LLC history to reduce latency. The options are Enable, Disable, and
Auto .
Snoop Throttle Configuration
Use this feature to set the level of snoop throttle for the PCH, which will determine how
much speed to decrease in operation when the system is in the snoop state. The options
are Disabled, Low, Medium, High, and
Auto
.
PCIe Remote P2P (Peer-to-Peer) Relaxed Ordering
Select Disable to support PCIe remote peer-to-peer relaxed writing ordering, which will
allow hardware to enforce peer-to-peer write ordering. The options are Enable and
Disable .
