Clemens Ladisch 7811fb8f40 [PATCH] hpet-RTC: cache the comparator register ... Reads from an HPET register require a round trip to the south bridge and are almost as slow as PCI reads. By caching the last value we've written to the comparator register, we can eliminate all HPET reads from the fast path in the emulated RTC interrupt handler.
