AGP Control Register
DevA:0xB0
Default: 0000 0000h
Bits
Description
31:10 Reserved.
9
CALDIS: calibration cycle disable.
1=Calibration cycles (as defined in DevA:0xA8[PCALCYC])
are disabled.
8
APEREN: graphics aperture enable.
This bit controls no hardware in the IC. It is expected that the
state of this bit is copied into the host by software.
7
GTLBEN: graphics translation look-aside buffer enable.
This bit controls no hardware in the IC. It
is expected that the state of this bit is copied into the host by software.
6:0
Reserved.
Attribute: Read-write.
AGP Aperture Size Register
DevA:0xB4
Default: 0001 0F00h
Bits
Description
31:28
PGSZSEL: page size select.
Read-write. The only legal value for these bits is 0000b, which specifies
a 4-kilobyte page.
27
Reserved.
26:16
Page size support.
Read only. These bits are fixed in their default state to indicate that the IC
supports 4-kilobyte pages.
15:12 Reserved.
Attribute: See below.
2:0
DRATE: data transfer mode rate.
This field is combined with DevA:0xA4[AGP3MD] to specify
the AGP data rate as follows:
