+ * 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. The
+ * tricky parts would be in detecting when some of the levels had been
+ * ejected from texture memory by other textures and preventing the
+ * 4th allocation (for all the smallest mipmap levels) from kicking out
+ * any of the first three.
