-/* GTT is the Global Translation Table for the graphics pipeline.

- * it allows you to set a range (the first two parameters) to point
- * to a physical address (third parameter);the physical address is
- * incremented by a count (fourth parameter) for each GTT in the
- * range.
- * Why do it this way? For ultrafast startup,
- * we can point all the GTT entries to point to one page,
- * and set that page to 0s:
- * memset(physbase, 0, 4096);
- * setgtt(0, 4250, physbase, 0);
- * this takes about 2 ms, and is a win because zeroing
