| | | | | | | | | | | | | | | | | | | | | | | | | of time that the laptop was suspending. Thus, select() calls that might have suspended rather than firing at 1hr + "time suspended" since the timer was posted. Adding: options APM_FIXUP_CALLTODO to the kernel config enables the patch. [ This patch was slightly modified to use a consistant indent style and I removed some unused local variables. After this has been tested a few weeks we'll make the options the default, so for now I'm now documenting it in LINT.

* init_main.c subr_autoconf.c:Justin T. Gibbs1997-09-211-81/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for "interrupt driven configuration hooks". A component of the kernel can register a hook, most likely during auto-configuration, and receive a callback once interrupt services are available. This callback will occur before the root and dump devices are configured, so the configuration task can affect the selection of those two devices or complete any tasks that need to be performed prior to launching init. System boot is posponed so long as a hook is registered. The hook owner is responsible for removing the hook once their task is complete or the system boot can continue. kern_acct.c kern_clock.c kern_exit.c kern_synch.c kern_time.c: Change the interface and implementation for the kernel callout service. The new implemntaion is based on the work of Adam M. Costello and George Varghese, published in a technical report entitled "Redesigning the BSD Callout and Timer Facilities". The interface used in FreeBSD is a little different than the one outlined in the paper. The new function prototypes are: struct callout_handle timeout(void (*func)(void *), void *arg, int ticks); void untimeout(void (*func)(void *), void *arg, struct callout_handle handle); If a client wishes to remove a timeout, it must store the callout_handle returned by timeout and pass it to untimeout. The new implementation gives 0(1) insert and removal of callouts making this interface scale well even for applications that keep 100s of callouts outstanding. See the updated timeout.9 man page for more details. Notes: svn path=/head/; revision=29680

* Man the liferafts! Here comes the long awaited SMP -> -current merge!Peter Wemm1997-04-261-2/+2
| | | | | | | | | | | | | | | | | | | There are various options documented in i386/conf/LINT, there is more to come over the next few days. The kernel should run pretty much "as before" without the options to activate SMP mode. There are a handful of known "loose ends" that need to be fixed, but have been put off since the SMP kernel is in a moderately good condition at the moment. This commit is the result of the tinkering and testing over the last 14 months by many people. A special thanks to Steve Passe for implementing the APIC code! Notes: svn path=/head/; revision=25164

* Improved biasing of i586 clock by adjusting for hardclock() latency.Bruce Evans1996-10-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | I decided to do this for every hardclock() call instead of lazily in microtime(). The lazy method is simpler but has more overhead if microtime() is called a lot. CPU_THISTICKLEN() is now a no-op and should probably go away. Previously it did nothing directly but had the side effect of setting i586_last_tick for CPU_CLOCKUPDATE() and i586_avg_tick for debugging. CPU_CLOCKUPDATE() now uses a better method and i586_avg_tick is too much trouble to maintain. Reduced nesting of #includes in the usual case. Increased nesting of #includes when CLOCK_HAIR is defined. This is a kludge to get typedefs for inline functions only when the inline functions are used. Normally only kern_clock.c defines this. kern_clock.c can't include the i386 headers directly. Removed unused LOCORE support. Notes: svn path=/head/; revision=19172

| | | | | | | | | | | | | | | | | | | | | | | | | Submitted by: terry (terry lambert) This is a composite of 3 patch sets submitted by terry. they are: New low-level init code that supports loadbal modules better some cleanups in the namei code to help terry in 16-bit character support some changes to the mount-root code to make it a little more modular.. NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able to test those cases.. certainly mounting root of disk still works just fine.. mfs should work but is untested. (tomorrows task) The low level init stuff includes a total rewrite of init_main.c to make it possible for new modules to have an init phase by simply adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can be added to the kernel without editing any other files other than the 'files' file.

* Redo Kernel NTP PLL support, kernel side.Garrett Wollman1994-09-181-10/+575
| | | | | | | | | | | | | | | | | | | | This code is mostly taken from the 1.1 port (which was in turn taken from Dave Mills's kern.tar.Z example). A few significant differences: 1) ntp_gettime() is now a MIB variable rather than a system call. A few fiddles are done in libc to make it behave the same. 2) mono_time does not participate in the PLL adjustments. 3) A new interface has been defined (in <machine/clock.h>) for doing possibly machine-dependent things around the time of the clock update. This is used in Pentium kernels to disable interrupts, set `time', and reset the CPU cycle counter as quickly as possible to avoid jitter in microtime(). Measurements show an apparent resolution of a bit more than 8.14usec, which is reasonable given system-call overhead. Notes: svn path=/head/; revision=2858
