Processor Uncore Configuration
Registers
The processor supports PCI configuration space accesses using the mechanism denoted
as Configuration Mechanism in the PCI specification as defined in the latest revision of
the PCI Local Bus Specification, as well as the PCI Express* enhanced configuration
mechanism as specified in the latest revision of the PCI Express Base Specification. All
the registers are organized by bus, device, function, and so forth, as defined in the PCI
Express Base Specification. All processor registers appear on the PCI bus assigned for
the processor socket. Bus number is derived by the max bus range setting and
processor socket number. All multi-byte numeric fields use “little-endian” ordering (that
is, lower addresses contain the least significant parts of the field).

Processor Uncore Configuration Structure (PCI
Bus — FFh)
The processor Uncore contains the following PCI 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 max bus range setting and processor socket number.
