| 39 | * |
||
| 40 | * Each mipmap-level contains all of it's layers (ie. all cubmap |

| 41 | * faces, all 1d/2d array elements, etc). The texture sampler is |
||
| 42 | * programmed with the start address of each mipmap level, and hw |

||
| 46 | * |
||
| 47 | * For cubemap and 2d array, each layer contains all of it's mipmap |
||
| 48 | * levels (layer_first layout). |

| 50 | * 3d textures are layed out as on a3xx, but unknown about 3d-array |

||
| 53 | * In either case, the slice represents the per-miplevel information, |
||
| 54 | * but in layer_first layout it only includes the first layer, and |
||
| 55 | * an additional offset of (rsc->layer_size * layer) must be added. |
