120 /* * for most pre nv50 cards setting a log2P of 7 (the common max_log2p * value) is no different to 6 (at least for vplls) so allowing the MNP * calc to use 7 causes the generated clock to be out by a factor of 2. * however, max_log2p cannot be fixed-up during parsing as the * unmodified max_log2p value is still needed for setting mplls, hence * an additional max_usable_log2p member */
