Note there is no loss of functionality here, at least on radeon
hardware. It just comes down to which MMU gets used for access to
system memory, the AGP MMU on the chipset or the MMU built into the
GPU. On powerpc hardware, AGP has been particularly unstable, and
IIRC, AGP has been disabled by default on radeon on powerpc for a
while.
So this basically just drops support for the AGP GART? What happens to the AGP signalling rates (beyond the base rate)?
