2062 | * | |
2063 | * offset (8 bit): opcode | |
2064 | * | |
2065 | * This opcode is meant to set NV_PFB_CFG0 (0x100200) appropriately so | |
2066 | * that the hardware can correctly calculate how much VRAM it has | |
2067 | * (and subsequently report that value in NV_PFB_CSTATUS (0x10020C)) | |
2068 | * | |
2069 | * The implementation of this opcode in general consists of two parts: | |
2070 | * 1) determination of the memory bus width | |
2071 | * 2) determination of how many of the card's RAM pads have ICs attached | |
2072 | * | |
2073 | * 1) is done by a cunning combination of writes to offsets 0x1c and | |
2074 | * 0x3c in the framebuffer, and seeing whether the written values are | |
2075 | * read back correctly. This then affects bits 4-7 of NV_PFB_CFG0 | |
2076 | * | |
2077 | * 2) is done by a cunning combination of writes to an offset slightly | |
2078 | * less than the maximum memory reported by NV_PFB_CSTATUS, then seeing | |
2079 | * if the test pattern can be read back. This then affects bits 12-15 of | |
2080 | * NV_PFB_CFG0 | |
2081 | * | |
2082 | * In this context a "cunning combination" may include multiple reads | |
2083 | * and writes to varying locations, often alternating the test pattern | |
2084 | * and 0, doubtless to make sure buffers are filled, residual charges | |
2085 | * on tracks are removed etc. | |
2086 | * | |
2087 | * Unfortunately, the "cunning combination"s mentioned above, and the | |
2088 | * changes to the bits in NV_PFB_CFG0 differ with nearly every bios | |
2089 | * trace I have. | |
2090 | * | |

2092 | * we started was correct, and use that instead | |
