* Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.Poul-Henning Kamp1998-05-281-11/+14
| | | | | | | | | | | | | | | | | | | | | | | Clean up (or if antipodic: down) some of the msgbuf stuff. Use an inline function rather than a macro for timecounter delta. Maintain process "on-cpu" time as 64 bits of microseconds to avoid needless second rollover overhead. Avoid calling microuptime the second time in mi_switch() if we do not pass through _idle in cpu_switch() This should reduce our context-switch overhead a bit, in particular on pre-P5 and SMP systems. WARNING: Programs which muck about with struct proc in userland will have to be fixed. Reviewed, but found imperfect by: bde Notes: svn path=/head/; revision=36441

* Restrict idleprio to superuser:David Greenman1998-02-041-1/+11
| | | | | | | | | | | | Realtime priority has to be restricted for reasons which should be obvious. However, for idle priority, there is a potential for system deadlock if an idleprio process gains a lock on a resource that other processes need (and the idleprio process can't run due to a CPU-bound normal process). Fix me! XXX PR: 5639 Notes: svn path=/head/; revision=33102

* Man the liferafts! Here comes the long awaited SMP -> -current merge!Peter Wemm1997-04-261-2/+4
| | | | | | | | | | | | | | | | | | | 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
