| 134 | * It is used to translate graphics addresses to physical |

| 136 | * The setgtt function adds a further bit of flexibility: |
| 137 | * it allows you to set a range (the first two parameters) to point |
| 138 | * to a physical address (third parameter);the physical address is |
| 139 | * incremented by a count (fourth parameter) for each GTT in the |
| 140 | * range. |
| 141 | * Why do it this way? For ultrafast startup, |
| 142 | * we can point all the GTT entries to point to one page, |
| 143 | * and set that page to 0s: |
| 144 | * memset(physbase, 0, 4096); |
| 145 | * setgtt(0, 4250, physbase, 0); |
| 146 | * this takes about 2 ms, and is a win because zeroing |
| 147 | * the page takes a up to 200 ms. |
