+/* Texture Layout on a3xx:
+ *
+ * Each mipmap-level contains all of it's layers (ie. all cubmap
+ * faces, all 1d/2d array elements, etc). The texture sampler is
+ * programmed with the start address of each mipmap level, and hw
+ * derives the layer offset within the level.
+ *
+ * Texture Layout on a4xx+:
+ *
+ * For cubemap and 2d array, each layer contains all of it's mipmap
+ * levels (layer_first layout).
+ *
+ * 3d textures are layed out as on a3xx, but unknown about 3d-array
+ * textures.
+ *
+ * In either case, the slice represents the per-miplevel information,
+ * but in layer_first layout it only includes the first layer, and
+ * an additional offset of (rsc->layer_size * layer) must be added.
