+- * We need to read back the CMP register on certain HPET

+- * logic. With small deltas this might actually be too late as
+- * the counter could already be higher than the compare value
+- * at that point and we would wait for the next hpet interrupt
+- * forever. We found out that reading the CMP register back
+- * forces the transfer so we can rely on the comparison with
+- * the counter register below. If the read back from the
+- * compare register does not match the value we programmed
+- * then we might have a real hardware problem. We can not do
+- * much about it here, but at least alert the user/admin with
+- * a prominent warning.
+- * An erratum on some chipsets (ICH9,..), results in comparator read
+- * immediately following a write returning old value. Workaround
+- * for this is to read this value second time, when first
+- * read returns old value.
++ * HPETs are a complete disaster. The compare register is
++ * based on a equal comparison and neither provides a less
++ * than or equal functionality (which would require to take
++ * the wraparound into account) nor a simple count down event
++ * mode. Further the write to the comparator register is
++ * delayed internally up to two HPET clock cycles in certain
++ * 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
++ * the event. The minimum programming delta for the generic
++ * clockevents code is set to 1.5 * HPET_MIN_CYCLES.
