But it is something like that:
intel_i810_configure:
pci_read_config_dword(intel_private.pcidev, I810_GMADDR, &temp);
agp_bridge->gart_bus_addr = (temp & PCI_BASE_ADDRESS_MEM_MASK);
agp_copy_info:
info->aper_base = bridge->gart_bus_addr;
drm_agp_init:
head->base = head->agp_info.aper_base;
dev->agp = head
i915_gem_init_ringbuffer:
ring->map.offset = dev->agp->base + obj_priv->gtt_offset;
This address is directly used to create a userspace mapping.
