- * GTT is the Global Translation Table for the graphics pipeline. It is used to translate
- * graphics addresses to physical memory addresses. As in the CPU, GTTs map 4K pages.
- *
- * The setgtt function adds a further bit of flexibility: 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 the page takes up to 200 ms.
- *
- * This call sets the GTT to point to a linear range of pages starting at physbase.
