We allocate a few objects into the GGTT that we never need to access via the mappable aperture (such as contexts, status pages). We can request that these are bound high in the VM to increase the amount of mappable aperture available. However, anything that may be frequently pinned (such as logical contexts) we want to use the fast search & insert.
