IIO Functional Description
6.3.4
Technologies Supported over PCI Express
6.3.4.1
3.0 Protocol Enhancements
Supported enhancements are
• Transaction Processing Hints (TPH)
• Atomic Operation Completer Capability
• Atomic Operation Completer Capability
6.3.5
32/64 Bit Addressing
For inbound and outbound memory reads and writes, the IIO module supports the 64-
bit address format. If an outbound transaction’s address is less than 4 GB, the IIO
module will issue the transaction with a 32-bit addressing format on PCI Express. Only
if the address is greater than 4 GB will the IIO module initiate a transaction with 64-bit
addressing format.
bit address format. If an outbound transaction’s address is less than 4 GB, the IIO
module will issue the transaction with a 32-bit addressing format on PCI Express. Only
if the address is greater than 4 GB will the IIO module initiate a transaction with 64-bit
addressing format.
Note:
The IIO allows, as a receiver, a 64bit address format packet for requests below the
4 GB boundary (where the upper 32 bit address bits are zero).
6.3.6
Direct Media Interface (DMI)
The Direct Media Interface (legacy Port) in the IIO module is responsible for sending
and receiving packets/commands to the PCH. The DMI port is typically strapped to
work with PCH but can also be strapped to operate as a standard PCI Express port.

Power Management
The IIO module power management is compatible with the PCI Bus Power Management
Interface Specification (PCI-PM). It is also compatible with the Advanced Configuration
and Power Interface (ACPI) Specification. The IIO module is designed to operate
seamlessly with operating systems employing these specifications.

Intel Virtualization Technology
Intel Virtualization Technology (Intel VT) is the technology that 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.
