Processor Configuration Registers
Datasheet
Note:
The Address Map includes a number of programmable ranges:
1. Device 0:
2. Device 2, Function 0:
The Base of GTT stolen Memory register (Device 0 A8) indicates the physical address
base which is 1MB aligned.
3. Device 2, Function 1:

PXPEPBAR – Egress port registers. Necessary for setting up VC1 as an isochronous
channel with fixed arbitration. (4KB window)
MCHBAR – Memory mapped range for IMC registers. For example, memory buffer
register controls. (16KB window)
PCIEXBAR - Flat memory-mapped address spaced to access device configuration
registers. This mechanism can be used to access PCI configuration space (0-FFh)
and Extended configuration space (100h-FFFh) for PCI Express devices. This
enhanced configuration access mechanism is defined in the PCI Express
specification. (64MB, 128MB, or 256MB window).
DMIBAR - This window is used to access registers associated with the processor
Serial Interconnect (DMI) register memory range. (4KB window)
GGCGMS – graphics control register, Graphics Mode Select. Used to select the
amount of main memory that is pre-allocated to support the internal graphics
device in VGA (non-linear) and Native (linear) modes. (0-64MB options).
GGCGGMS – graphics control register, GTT Graphics Memory Size. Used to select
the amount of main memory that is pre-allocated to support the Internal Graphics
Translation Table. (0-2MB options).
MMADR – IGD registers and internal graphics instruction port. (512KB window)
IOBAR – IO access window for internal graphics. Though this window address/data
register pair, using I/O semantics, the IGD and internal graphics instruction port
registers can be accessed. Note, this allows accessing the same registers as
MMADR.
GMADR – Internal graphics translation window (128MB, 256MB or 512MB window).
GTTADR - Internal graphics translation table location. (1MB window).
MMADR – Function 1 IGD registers and internal graphics instruction port (512KB
window).
