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
43 * derives the layer offset within the level.
45 * Texture Layout on a4xx:
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.
