The address bits masked for buddy address comparison.
The buddy system determines if two memory requests can be paired by
comparing bits 36-9 of the requests' physical addresses. However, the
comparison ignores the bits whose corresponding mask bits in this field are
set to 1. Conceptually, bits 36-9 in the physical address are ANDed with
the inverse (NOT) of bits 27-0 in this field before going into the
comparator.
This field accounts for the system's DRAM configuration. The intent is that
the buddy system improves DRAM bandwidth efficiency by pairing up memory
requests in a way that cuts down on DRAM management operations, such as
opening rows.
