R
AGP PIPE# or SBA[7:0] protocol transactions to DRAM do not get snooped and are, therefore, not
coherent with the processor caches. AGP FRAME# protocol transactions to DRAM are snooped. AGP
PIPE# and SBA[7:0] accesses to and from the hub interface are not supported. AGP FRAME# access
from an AGP master to the hub interface are also not supported. Only AGP FRAME# memory writes
from the hub interface are supported.
5.3.1.
AGP Target Operations
The MCH-M supports AGP cycles targeting main memory only. The MCH-M supports interleaved AGP
PIPE#] and AGP FRAME# transactions, or AGP SBA[7:0] and AGP FRAME# transactions.
