Configuration Process and Registers
2.1.2 Processor Uncore Devices (CPUBUSN0 (1))
The configuration registers for these devices are mapped as devices residing on the PCI
bus assigned for the processor socket.
• Device 10: Processor Power Control Unit. Device 10, Function 0-3 contains the
configurable PCU registers and resides at DID of 3CC0h-3CD0h.
• Device 11: Processor Interrupt Event Handling. Device 11, Function 3 contains the
Semaphore and Scratchpad configuration registers. Device 11, Function 0 contains
the processor Interrupt control registers.
• Device 12: Processor Core Broadcast. Device 12, Function 0-3 contains the
Unicast configuration registers, Function 6 contains the Caching agent broadcast
configuration registers for the Memory Controller. Function 7 contains the System
Address Decode registers.
• Device 13: Processor Core Broadcast. Device 13, Function 0-3 contain the Unicast
registers, Function 6 contains the Caching agent broadcast configuration registers
for the Memory Controller.
• Device 14: Processor Home Agent. Device 14, Function 0 contains the processor
Home Agent Target Address configuration registers for the Memory Controller.
Device 14, Function 1 contains processor Home Agent performance monitoring
registers.
