thorpej | Introduce a device call "device-is-system-todr", which allows the
platform device tree to be consulted if there are multiple TODR / RTC
devices present on the system; if the call is not supported, the behavior
is un-changed: the first TODR device is attached, all others ignored. If
the call is supported, devices other than the specified system TODR are
skipped.
Implement this device call for FDT.

simonb | Print the "preposterous TOD clock time" message only if the RTC is
before very late 2020 (1/1/2021 minus a few leap days) instead of
late 1994. Someone(TM) should remember to adjust this in somewhat
less than 26 years.

thorpej | branches: 1.46.8; 1.46.10;
- In todr_gettime(), in the todr_gettime_ymdhms, pre-zero the clock_ymdhms
struct before asking the back-end to fill it in.
- Tidy up todr_settime() a teensy bit.
|
| 1.45 |
| 01-Jan-2020 |
thorpej | Now that we know if we're shutting down, enable locking in resettodr().
In the shutting_down case, we acquire the todr_mutex as a trylock. Under
most circumstances, this lock will be uncontended. But if we happen to
panic while accessing the TOD clock (via clock_settime() or whatever),
then trylock will prevent us from getting stuck (and a warning will be
displayed on the console).
|
| 1.44 |
| 01-Jan-2020 |
thorpej | First steps towards properly serializing access to the TOD clock.
- Add a mutex around the TODR, and provide lock/unlock/lock-owned
functions to manipulate it.
- Rename inittodr() to todr_set_systime() and resettodr() to
todr_save_systime() to better reflect what they do. These functions
are intended to be called with the TODR lock held, which will allow
for a pattern like:
-> todr_lock()
-> todr_save_systime()
-> [do machine-dependent stuff to sleep/suspend]
-> [magically awaken]
-> todr_set_systime(...)
-> todr_unlock()
- Provide historically-named wrappers inittodr() and resettodr() that
do the dance of acquiring / releasing the lock around the actual
substance.
NOTE: resettodr()'s use of the TODR lock is currently disabled (and
todr_save_systime() does not assert it's held) until such time as
issues around shutdown / reboot under duress can be addressed.

| 01-Jan-2020 |
thorpej | Fix some issues around todr_wenable():
- As previously defined, it was not possible to return an error from the
back-end RTC driver. Make it a real function so that it can do so.
- Only the mc146818 and mk48txx drivers used it (for historical reasons).
Centralize the logic for how it's used in kern_todr.c (and make it private
to that file) for consistency.
|
| 1.42 |
| 01-Jan-2020 |
thorpej | todr_gettime() and todr_settime() are not referenced outside of kern_todr.c,
so make them private to that file.
|
| 1.41 |
| 01-Jan-2020 |
thorpej | Remove superfluous splclock()/splx() pair around tc_setclock().
|

maxv | The whole 'tv' structure gets added to the RND pool, so clear it first,
otherwise each random buffer gets tainted by uninitialized bytes from the
padding.

PR/49207: Kamil Rytarowski: Add sys/clock.h with generic time macros
(derived from clock_subr.h). Keep clock_subr.h with the kernel structures
and functions to reduce diffs, and have clock.h only include standalone
constants and macros.

Update default TOD value to 2010/01/01 12:00:00.
|
| 1.32 |
| 12-Dec-2009 |
tsutsui | Remove `volatile' qualifier from argument types of
struct timeval passed to todr_gettime(9) and todr_settime(9).
We no longer have an ancient and volatile struct timeval `time'
global since we have switched to MI timercounter(9) on all port.
XXX1: some of these RTC drivers still assume 32bit time_t
XXX2: some of these should be rewritten to use todr_[gs]ettime_ymdhms()
XXX3: todr(9) man page doesn't mention todr_[gs]ettime_ymdhms()

Pass the filesystem time to clock drivers in the todr_chip_handle, so that
vax, and pmax can use it.

gdamore | Comment nit (remove first person), from simon@.
|
| 1.20 |
| 12-Sep-2006 |
gdamore | Centralize rtc_offset handling for ports that __HAVE_GENERIC_TODR and use
a simple second counter instead of the clock_ymdhms support.
|
| 1.19 |
| 12-Sep-2006 |
gdamore | Remove attempt to incorrectly support fictional double leap seconds.
While here, make the comparisions for hour, min, and sec use ">" consistently
like the date comparisions.
|
| 1.18 |
| 12-Sep-2006 |
gdamore | Fix to compile on platforms without __HAVE_GENERIC_TODR. Sorry about
that. Pointed out jdc@ and he@.
|
| 1.17 |
| 12-Sep-2006 |
gdamore | Add some optional debug (enabled with TODR_DEBUG) to see what your RTC
is giving you. Also, while here, bump the threshold for "preposterous"
dates by 20 years. Now any date earlier than late 1994 is considered
preposterous.
|
| 1.16 |
| 11-Sep-2006 |
gdamore | Don't bother checking wday, that breaks some clock chips. Thank to Kurt Schreiner <ks at ub dot uni-mainz dot de>.
|

gdamore | Allow for leap seconds.

gavan | dsrtc_settime already takes a volatile struct timeval *, also qualify
with volatile for dsrtc_gettime.
|

|

Run tc_setclock at splclock(). Suggested by kardel@.

dogcow | Now compiles on systems without __HAVE_GENERIC_TODR
|
| 1.10 |
| 07-Sep-2006 |
gdamore | Eliminate the 2038 year check, because clock_ymdhms_to_sec already performs
that check. So instead, we test to make sure we have a non-negative second
after the conversion.
While here, we also add a check to round the second counter up when setting
time if we are more than half-way into the second.
|
| 1.9 |
| 07-Sep-2006 |
gdamore | Add a few consistency checks for ymdhms. Taken from the mc146818 code.
|
| 1.8 |
| 07-Sep-2006 |
uwe | Make timeval argument to todr_settime volatile to keep non-timecounter
ports happy.
|
| 1.7 |
| 07-Sep-2006 |
uwe | Mark sizeof(tvp->tv_sec) check CONSTCOND.
No space between the sizeof and the paren.
|
| 1.6 |
| 07-Sep-2006 |
gdamore | Add support for new todr entry points for drivers- todr_gettime_ymdhms and
todr_settime_ymdhms. This allows drivers to avoid repeated conversions, and
allows us to centralize check for Y2038 overflow. As discussed on
tech-kern.
|
| 1.5 |
| 05-Sep-2006 |
matt | Before calling todr_gettime, fill in tv.tv_sec. At least one port (vax)
needs that functionality.
|
| 1.4 |
| 03-Sep-2006 |
gdamore | Update the base time (used when no filesystem or rtc time exists) to 12pm,
Jan 1, 2006. This is somewhat arbitrary, but its a heck of a lot better than
mid 1991. :-)
|
| 1.3 |
| 03-Sep-2006 |
gdamore | branches: 1.3.2;
Don't warn about RTC losing/gaining days if the filesystem time is bogus.
|
| 1.2 |
| 03-Sep-2006 |
gdamore | Incorporate changes from x86/i386 as follows:
1) don't set a clock when panicing during early boot
2) if the filesystem time is newer than the rtc time (by at least 2 days) then
revert to the filesystem time.
3) use x86 style messaging.
We still use a threshold of 2 days of gain or loss in time to warn though.
|
| 1.1 |
| 02-Sep-2006 |
gdamore | Add MI implementation of inittodr, todr_attach, and resettodr.
This is triggered upon __HAVE_GENRIC_TODR in machine/types.h. Conversion of
evbmips port forthcoming.
