.SH DESCRIPTION
All pointers embedded in the Reality Coprocessor display list are
segment addresses composed of a segment base and offset address.
The base physical addresses for these segments are set using the
.I gSPSegment

The actual addresses read by the RSP go thru the following translation:
.Ex
real_address = base_address[segment_number] + offset.
