 640 * architected results from PDC_PIM/transfer hpmc on a PA2.0 machine
 641 *
 642 * Note that PDC_PIM doesn't care whether or not wide mode was enabled
 643 * so the results are different on  PA1.1 vs. PA2.0 when in narrow mode.
 644 *
 645 * Note also that there are unarchitected results available, which
 646 * are hversion dependent. Do a "ser pim 0 hpmc" after rebooting, since
 647 * the firmware is probably the best way of printing hversion dependent
 648 * data.
