4 * This file contains the PC-specific time handling details:
5 * reading the RTC at bootup, etc..
6 * 1994-07-02 Alan Modra
7 * fixed set_rtc_mmss, fixed time.year for >= 2000, new mktime
8 * 1995-03-26 Markus Kuhn
9 * fixed 500 ms bug at call to set_rtc_mmss, fixed DS12887
10 * precision CMOS clock update
11 * 1996-05-03 Ingo Molnar
12 * fixed time warps in do_[slow|fast]_gettimeoffset()
13 * 1997-09-10 Updated NTP code according to technical memorandum Jan '96
14 * "A Kernel Model for Precision Timekeeping" by Dave Mills
15 * 1998-09-05 (Various)
16 * More robust do_fast_gettimeoffset() algorithm implemented
17 * (works with APM, Cyrix 6x86MX and Centaur C6),
18 * monotonic gettimeofday() with fast_get_timeoffset(),
19 * drift-proof precision TSC calibration on boot
20 * (C. Scott Ananian <cananian@alumni.princeton.edu>, Andrew D.
21 * Balsa <andrebalsa@altern.org>, Philip Gladstone <philip@raptor.com>;
22 * ported from 2.0.35 Jumbo-9 by Michael Krause <m.krause@tu-harburg.de>).
23 * 1998-12-16 Andrea Arcangeli
24 * Fixed Jumbo-9 code in 2.1.131: do_gettimeofday was missing 1 jiffy
25 * because was not accounting lost_ticks.
26 * 1998-12-24 Copyright (C) 1998 Andrea Arcangeli
27 * Fixed a xtime SMP race (we need the xtime_lock rw spinlock to
28 * serialize accesses to xtime/lost_ticks).
