Eric,
You put a preprocessor warnning for 64MB MMIO Hole in the amdk8/northbridge.c.
#warning "FIXME improve mtrr.c so we don't use up all of the mtrrs with a 64M MMIO hole"
What exactly is it ? Is that for the AGP aperture (you call it IOMMU_APERTURE) ?
No, although the IOMMU_APERATURE plays a role there. But this was implemented before I implemented the IOMMU_APERATURE code in misc_control.c
The IOMMU_APERATURE is just another large I/O region as far as that code is concerned.
But you also used it for AGP aperture in misc_control.c. Is there any reason to do this ? Or the AGP aperture can actually be anything else.
