Locking for todr got pushed down into inittodr and the client

libraries it calls (although some might not be doing it right). We are serialized right now by giant as well. This means the splsoftclock are now an anachronism that has no benefit, even marking where locking needs to happen. Remove them.

Now that all platforms use genclock, shuffle things around slightly

for better structure. Much of this is related to , which should really have been called , but unless and until we need the name, the repocopy can wait. In general the kernel does not know about minutes, hours, days, timezones, daylight savings time, leap-years and such. All that is theoretically a matter for userland only. Parts of kernel code does however care: badly designed filesystems store timestamps in local time and RTC chips almost universally track time in a YY-MM-DD HH:MM:SS format, and sometimes in local timezone instead of UTC. For this we have on the other hand, deals with time_t, timeval, timespec and so on. These know only seconds and fractions thereof. Move inittodr() and resettodr() prototypes to . Retain the names as it is one of the few surviving PDP/VAX references. Move startrtclock() to on relevant platforms, it is a MD call between machdep.c/clock.c. Remove references to it elsewhere. Remove a lot of unnecessary includes. Move the machdep.disable_rtc_set sysctl to subr_rtc.c where it belongs. XXX: should be kern.disable_rtc_set really, it's not MD.

First part of a little cleanup in the calendar/timezone/RTC handling.

Move relevant variables to and fix #includes as necessary. Use libkern's much more time- & spamce-efficient BCD routines.

Add Timer device driver for power management events.

The code for suspend/resume is derived from APM device driver. Some people suggested the original code is somewhat buggy, but I'd like to just move it from apm.c without any major changes for the initial version. This code should be refined later. To use pmtimer to adjust time at resume time, add device pmtimer in your kernel config file, and add hint.pmtimer.0.at="isa" in your device.hints Reviewed by: -current, bde
