augustss 264f1d27c6 Get rid of register declarations. 2000-03-30 09:27:11 +00:00
thorpej b667a5a357 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

itojun 791a70292c correct ratecheck() signedness. without this fix, ratecheck() will never 
success again after first success with lasttime=(0,0).
 2000-02-16 12:36:19 +00:00
cgd dd84ecc7ac Implement ratecheck(), a function which can help programmers implement 
rate-limited actions.  See ratecheck(9) for details of its use.

hwr 6d638c3405 If time delta is larger than thresh. Use 10* adj factor. Make this 
work for negative deltas too. From NAKAJIMA Yoshihiro <nakayosh@kcn.ne.jp>
in kern/8589.

tron 992156ec89 Remove the prototype for settime(), it is in "sys/time.h" now. 1999-08-16 18:53:55 +00:00
tron 35ba1291c8 Make settime() public because we need to use it for the Linux emulation. 1999-08-16 18:42:25 +00:00
thorpej eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions, 
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.

thorpej 1c5f2999b2 Make sure `olddelta' is a valid pointer before performing the guts of 
the adjtime(2) system call.  Fixes PR #7721, Darren Reed.

tls 3a98883bd3 Don't allow the time to be set backwards if in highly secure mode, since this would allow inode change times to be manipulated. 1997-04-26 21:22:57 +00:00
jtc 2114c082ae In nanosleep, use local error variable when storing rqtp in so that 
an error from a failed tsleep will still be returned to the caller.

perry b89a3425b7 Eliminate obsolete TIMEZONE and DST options. 
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.

cgd e7af2a8237 * catch up with system call argument type fixups/const poisoning. 
* Fix arguments to various copyin()/copyout() invocations, to avoid
  gratuitous casts.
* Some KNF formatting fixes
 1996-12-22 10:21:06 +00:00
cgd 9ed8ce3b8f clean up a few spaces vs. tabs and KNF bogons. Make this compile 
cleanly with -Wall -Wstrict-prototypes -Wmissing-prototypes -Wcast-qual.

jtc d22cdecb45 Add clock_gettime, clock_settime, and clock_getres 1996-11-15 22:44:25 +00:00
cgd 574f71ab26 replace a construction in sys_setitimer() that was too tricky for its 
(and my!) own good with a more straightforward one that is equally (and
more apparently) correct.
 1996-10-24 04:35:33 +00:00
fvdl 56a654e17f Changes for NVSv3 code: pull in more NFS include files into kern_time.c 
to get types right (overkill for just one function call, but oh well).
Clear B_NEEDCOMMIT in bdwrite().
 1996-02-18 11:57:06 +00:00
christos 20df3b41ab uipc_proto.c: No need for the forward decls anymore; everything is prototyped. 
kern_time.c: add header to get the NFS prototypes if needed.

whine so much.
 1993-07-13 22:13:15 +00:00
andrew 0e6cb953ea ANSIfications - removed all implicit function return types and argument

general prototypes.  Casts where necessary.
