+ * chipsets (ATI, ICH9,10). Some newer AMD chipsets have even
+ * longer delays. We worked around that by reading back the
+ * compare register, but that required another workaround for
+ * ICH9,10 chips where the first readout after write can
+ * return the old stale value. We already had a minimum
+ * programming delta of 5us enforced, but a NMI or SMI hitting
+ * between the counter readout and the comparator write can
+ * move us behind that point easily. Now instead of reading
+ * the compare register back several times, we make the ETIME
+ * decision based on the following: Return ETIME if the
+ * counter value after the write is less than HPET_MIN_CYCLES
+ * away from the event or if the counter is already ahead of
