• Device 6 — PCI Express Root Port 4. Logically this appears as a “virtual” PCI-to-

PCI bridge residing on PCI bus 0 and is compliant with PCI Express Specification 
revision 1.0. Device 6 contains the standard PCI Express/PCI configuration 
registers including PCI Express Memory Address Mapping registers. It also contains 
the extended PCI Express configuration space that includes PCI Express error 
status/control registers and Isochronous and Virtual Channel controls.

• Device 8 — Integrated I/O Core. This device contains the Standard PCI registers 

for each of its functions. This device implements four functions; Function 0 contains 
Address Mapping, Intel

®

 Virtualization Technology (Intel

®

 VT) for Directed I/O 

(Intel VT-d) related registers and other system management registers. Function 1 
contains Semaphore and Scratchpad registers, Function 3 contains System 
Control/Status registers and Function 4 contains miscellaneous control/status 
registers on power management and throttling.

• Device 16 — Intel

®

 QuickPath Interconnect. Device 16, Function 0 contains the 

Intel

®

QuickPath Interconnect configuration registers for Intel QuickPath 

Interconnect Link. Device 16, Function 1 contains the routing and protocol.

The processor Uncore contains the following devices within a single, physical 
component. The configuration registers for these devices are mapped as devices 
residing on the PCI bus assigned for the processor socket. Bus number is derived by 
the maximum bus range setting and processor socket number.

• Device 0 — Generic processor non-core. Device 0, Function 0 contains the generic 

non-core configuration registers for the processor and resides at DID (Device ID) of 
2C50-7h. Device 0, Function 1 contains the System Address Decode registers and 
resides at DID of 2C81h.

• Device 2 — Intel QuickPath Interconnect. Device 2, Function 0 contains the Intel 

QuickPath Interconnect configuration registers for Intel QuickPath Interconnect 
Link 0 and resides at DID of 2C90h. Device 2, Function 1 contains the physical layer 
registers for Intel QuickPath Interconnect Link 0 and resides at DID of 2C91h.

• Device 3 — Integrated Memory Controller. Device 3, Function 0 contains the 

general registers for the Integrated Memory Controller and resides at DID of 
2C98h. Device 3, Function 1 contains the Target Address Decode registers for the 
Integrated Memory Controller and resides at DID of 2C99h. Device 3, Function 4 
contains the test registers for the Integrated Memory Controller and resides at DID 
of 2C9C.

• Device 4 — Integrated Memory Controller Channel 0. Device 4, Function 0 

contains the control registers for Integrated Memory Controller Channel 0 and 
resides at DID of 2CA0h. Device 4, Function 1 contains the address registers for 
Integrated Memory Controller Channel 0 and resides at DID of 2CA1h. Device 4, 
Function 2 contains the rank registers for Integrated Memory Controller Channel 0 
and resides at DID of 2CA2h. Device 4, Function 3 contains the thermal control 
registers for Integrated Memory Controller Channel 0 and resides at DID of 2CA3h.
