AGP Device Graphic Virtual Memory Aperture Register
DevA:0x10
It is expected that the state of this register is copied into the host by software. This register controls no hard-
ware in the IC.
Default: 0000 0000 0000 0008h
Bits
Description
63:32
APBARHI.
Read-write. Aperture base address register high. Note: bits[63:40] are required to be
programmed low; setting any of these bits high results in undefined behavior. Note: if
DevA:0x10[64BIT]=0, then these bits are read only, all zero.
31:22
APBARLO.
Aperture base address register low. These bits are a combination of read-write and read-
only zero, based on the state of DevA:0xB4[APSIZE]; see that register for details.
21:4
Reserved.
3
Read only. This bit is fixed at its default value to indicate that this register points prefetchable space.
2
64BIT: 64-bit pointer.
Read; write once. 1=DevA:0x10 is a 64-bit pointer. 0=DevA:0x10 is a 32-bit
pointer; bits[63:32] are reserved.
1:0
Read only. These bits are fixed at their default value to indicate that this register points memory space.
Attribute: See below.
AGP Device Subsystem ID and Subsystem Vendor ID Register
DevA:0x2C
Default: 0000 0000h
Bits
Description
31:16
Subsystem ID.
This field controls no hardware.
15:0
Subsystem vendor ID.
This field controls no hardware.
Attribute: Read; write once.
AGP Capabilities Pointer
DevA:0x34
Default: 0000 00A0h
Bits
Description
31:8
Reserved.
7:0
Capabilities pointer.
Specifies the offset in DevA:0 address space for the AGP capabilities block.
Attribute: Read only.
