Register Description

2.2

Platform Configuration Structure

The processor contains 6 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.

• 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
2C41h. Device 0, Function 1 contains the System Address Decode registers and
resides at DID of 2C01h.

• Device 2: Intel QPI. Device 2, Function 0 contains the Intel

QuickPath

Interconnect configuration registers for Intel QPI Link 0 and resides at DID of
2C10h. Device 2, Function 1 contains the physical layer registers for Intel QPI Link
0 and resides at DID of 2C11h.

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

registers for the Integrated Memory Controller and resides at DID of 2C18h. Device
3, Function 1 contains the Target Address Decode registers for the Integrated
Memory Controller and resides at DID of 2C19h. Device 3, Function 2 contains the
RAS registers for the Integrated Memory Controller and resides at DID of 2C1Ah.
Device 3, Function 4 contains the test registers for the Integrated Memory
Controller and resides at DID of 2C1Ch. Function 2 only applies to processors
supporting registered DIMMs.

• 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 2C20h. Device 4, Function 1 contains the address registers for Integrated
Memory Controller Channel 0 and resides at DID of 2C21h. Device 4, Function 2
contains the rank registers for Integrated Memory Controller Channel 0 and resides

RSVD

Reserved Bit. This bit is reserved for future expansion and must not be written. The PCI

Local Bus Specification, Revision 2.2 requires that reserved bits must be preserved. Any

software that modifies a register that contains a reserved bit is responsible for reading the

Reserved Bits

Some of the processor registers described in this section contain reserved bits. These bits

are labeled “Reserved”. Software must deal correctly with fields that are reserved. On

reads, software must use appropriate masks to extract the defined bits and not rely on

reserved bits being any particular value. On writes, software must ensure that the values

of reserved bit positions are preserved. That is, the values of reserved bit positions must

first be read, merged with the new values for other bit positions and then written back.

Note that software does not need to perform a read-merge-write operation for the

Configuration Address (CONFIG_ADDRESS) register.

Reserved

Registers

In addition to reserved bits within a register, the processor contains address locations in

the configuration space that are marked either “Reserved” or “Intel Reserved”. The

processor responds to accesses to “Reserved” address locations by completing the host

cycle. When a “Reserved” register location is read, a zero value is returned. (“Reserved”

registers can be 8, 16, or 32 bits in size). Writes to “Reserved” registers have no effect on

the processor. Registers that are marked as “Intel Reserved” must not be modified by

system software. Writes to “Intel Reserved” registers may cause system failure. Reads to

“Intel Reserved” registers may return a non-zero value.

Default Value

upon a Reset

Upon a reset, the processor sets all of its internal configuration registers to predetermined

default states. Some register values at reset are determined by external strapping

options. The default state represents the minimum functionality feature set required to

successfully bring up the system. Hence, it does not represent the optimal system

configuration. It is the responsibility of the system initialization software (usually BIOS) to

properly determine the DRAM configurations, operating parameters and optional system

features that are applicable, and to program the processor registers accordingly.

“ST” appended

to the end of a

bit name

The bit is “sticky” or unchanged by a hard reset. These bits can only be cleared by a

PWRGOOD reset.
