* Tests by numerous people have shown that many chipsets do not properlyMatthew Dillon2002-02-241-1/+1
| | | | | | | | | | | | | | latch the acpi timer, resulting in weird deltas. The problem is severe enough to adversely effect the timecounter code. Default to the 'safe' version of the get-timecount function. The probe will override it if a known-good chipset is found. This is temporary until a more complete solution is found.

* Use libgcc_p.a when -pg is in effect.David E. O'Brien2002-02-241-0/+4
| | | | | | | | | | | I am committing this here rather than in gcc/config/freebsd.h because the profiled libgcc only exists with the native system compiler. It is not created by a stock FSF build and we will never be able to get these bits committed to the FSF CVS repo. Thus this is very much a FreeBSD "native" issue.

* 1. Setup the user stack pointer before returning to a user trap handler.Jake Burkholder2002-02-232-0/+64
| | | | | | | | | | | | | | If we don't do this here there's a 1 instruction race where an interrupt could come in and crash the user process due to having no stack. 2. Pass %fsr to the user trap handler in %l4. Since %fsr can only be loaded from or stored to memory, we need to do some contortions and temporarily save it to the alternate global stack. 3. Reload the pcb and pcpu registers for traps in kernel mode, for sanity. Submitted by: tmm (1, 2) Notes: svn path=/head/; revision=91158

* Lock struct pgrp, session and sigio.Seigo Tanimura2002-02-2335-314/+1004
| | | | | | | | | | | | | | | | | | | | | | | | | | | | New locks are: - pgrpsess_lock which locks the whole pgrps and sessions, - pg_mtx which protects the pgrp members, and - s_mtx which protects the session members. Please refer to sys/proc.h for the coverage of these locks. Changes on the pgrp/session interface: - pgfind() needs the pgrpsess_lock held. - The caller of enterpgrp() is responsible to allocate a new pgrp and session. - Call enterthispgrp() in order to enter an existing pgrp. - pgsignal() requires a pgrp lock held.
