Disable TPH
TPH (TLP Processing Hint) is used for data-tagging with a destination ID and a few im-
portant attributes. It can send critical data to a particular cache without writing through to
memory. Select No for TLP Processing Hint support, which will allow a "TPL request" to
provide "hints" to help optimize the processing of each transaction occurred in the target
memory space. The options are Yes and No.
Prioritize TPH (TLP Processing Hint)
Select Enable to prioritize the TPL requests that will allow the "hints" to be sent to help
facilitate and optimize the processing of certain transactions in the system memory. The
options are Enable and Disable.
Relaxed Ordering
Select Yes to allow certain transactions to be processed and completed before other
transactions that have already been enqueued. The options are Yes and No.

platforms, providing greater reliability, security and availability in networking and data-
sharing. The options are Yes and No.
