The G400 does not have this restriction, but it still - * only has 5 offset pointers in the hardware. The trick on the G400 is - * upto the first 4 offset pointers point to mipmap levels. The last - * offset pointer tells how large the preceeding mipmap is. This value is - * then used to determine where the remaining mipmaps are. - * - * For example, if the first offsets[0] through offsets[2] are used as - * pointers, then offset[3] will be the size of the mipmap pointed to by - * offsets[2]. So mipmap level 3 will be at (offsets[2]+offsets[3]). For - * each successive mipmap level, offsets[3] is divided by 4 and added to - * the previous address. So mipmap level 4 will be at - * (offsets[2]+offsets[3]+(offsets[3] / 4)). - * - * The last pointer is selected by setting TO_texorgoffsetsel in its - * pointer. In the previous example, offset[2] would have - * TO_texorgoffsetsel or'ed in before writing it to the hardware. - * - * In the current driver all of the mipmaps are packed together linearly - * with mipmap level 0. Therefore offsets[0] points to the base of the - * texture (and has TO_texorgoffsetsel or'ed in), and offsets[1] is the - * size of the base texture. - * - * There is a possible optimization available here. At times the driver - * may not be able to allocate a single block of memory for the complete - * texture without ejecting some other textures from memory. It may be - * possible to put some of the lower mipmap levels (i.e., the larger - * mipmaps) in memory separate from the higher levels. - * - * The implementation should be fairly obvious, but getting "right" would - * likely be non-trivial. A first allocation for the entire texture would - * be attempted with a flag that says "don't eject other textures." If - * that failed, an additional allocation would be attmpted for just the - * base map. The process would repeat with the block of lower maps.
