41 * programmed with the start address of each mipmap level, and hw

44 * Texture Layout on a4xx+:
46 * For cubemap and 2d array, each layer contains all of it's mipmap
47 * levels (layer_first layout).
49 * 3d textures are layed out as on a3xx, but unknown about 3d-array
52 * In either case, the slice represents the per-miplevel information,
53 * but in layer_first layout it only includes the first layer, and
54 * an additional offset of (rsc->layer_size * layer) must be added.
