67eda20e FJ |
2482 | * This opcode is meant to set the PFB memory config registers |
2483 | * appropriately so that we can correctly calculate how much VRAM it | |
2484 | * has (on nv10 and better chipsets the amount of installed VRAM is | |
2485 | * subsequently reported in NV_PFB_CSTATUS (0x10020C)). | |
6ee73861 | 2486 | * |
67eda20e FJ |
2487 | * The implementation of this opcode in general consists of several |
2488 | * parts: | |
6ee73861 | 2489 | * |
67eda20e FJ |
2490 | * 1) Determination of memory type and density. Only necessary for |
2491 | * really old chipsets, the memory type reported by the strap bits | |
2492 | * (0x101000) is assumed to be accurate on nv05 and newer. | |
6ee73861 | 2493 | * |
67eda20e FJ |
2494 | * 2) Determination of the memory bus width. Usually done by a cunning |
2495 | * combination of writes to offsets 0x1c and 0x3c in the fb, and | |
2496 | * seeing whether the written values are read back correctly. | |
6ee73861 | 2497 | * |
67eda20e FJ |
2498 | * Only necessary on nv0x-nv1x and nv34, on the other cards we can |
2499 | * trust the straps. | |
6ee73861 | 2500 | * |
67eda20e FJ |
2501 | * 3) Determination of how many of the card's RAM pads have ICs |
2502 | * attached, usually done by a cunning combination of writes to an | |
2503 | * offset slightly less than the maximum memory reported by | |
2504 | * NV_PFB_CSTATUS, then seeing if the test pattern can be read back. | |
6ee73861 | 2505 | * |
67eda20e FJ |
2506 | * This appears to be a NOP on IGPs and NV4x or newer chipsets, both io |
2507 | * logs of the VBIOS and kmmio traces of the binary driver POSTing the | |
2508 | * card show nothing being done for this opcode. Why is it still listed | |
2509 | * in the table?! | |
