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. + * + * This array holds G400_TEX_MAXLEVELS pointers to remove an if-statement + * in a loop in mgaSetTexImages.
