cegger 83fde857cc buildfix: use PRIxPTR rather %lx. 2008-11-07 19:50:00 +00:00
rafal ca70a1c015 Pass / log return address in a few more places; proposed on tech-kern and 
ok'd by ad@ about 6 months ago.

matt 5a4f0c6b2b Change tree op members/typedefs to rbto_compare_* from rb_compare_* 2008-06-30 20:14:09 +00:00
ad 13c7f6ff40 Move lib/libkern/rb.h to sys/rb.h, so it can be used by kernel header 
files.

ad 7b8f512433 LOCKDEBUG: 
- Tweak it so it can also catch common errors with condition variables.
  The change to kern_condvar.c is not included in this commit and will
  come later.

- Don't call kmem_alloc() if operating in interrupt context, just fail
  the allocation and disable debugging for the object. Makes it safe
  to do mutex_init/rw_init/cv_init in interrupt context, when running
  a LOCKDEBUG kernel.
 2008-05-31 13:15:21 +00:00
ad a4e0004be3 LOCKDEBUG: try to speed it up a bit by not using so much global state. 
This will break the build briefly but will be followed by another commit
to fix that..

ad 81194e34f1 Allow rw_tryenter(&lock, RW_READER) to recurse, for vfs_busy(). 2008-05-06 17:11:45 +00:00
yamt 839080f755 lockdebug: try to detect recursive acquirements of read-write locks. 2008-05-03 06:24:55 +00:00
martin ce099b4099 Remove clause 3 and 4 from TNF licenses 2008-04-28 20:22:51 +00:00
ad 8f9c8f5ea5 lockdebug_barrier: disable preemption using the interrupt priority level, 
not crit_enter/crit_exit. Since this is called from mi_switch(), crit_exit
could recurse and skew statistics.
 2008-04-27 11:28:49 +00:00
ad feb4783fdf Replace use of CACHE_LINE_SIZE in some obvious places. 2008-03-27 18:30:15 +00:00
ad 057adba179 Make it compile if !LOCKDEBUG. 2008-02-18 18:31:10 +00:00
ad 7eb6056f9a Try to prevent more than one CPUs panicing when an error is detected. 2008-02-18 16:02:41 +00:00
ad 212c50dd1b Need sys/lock.h for SPINLOCK_SPIN_HOOK. 2008-01-05 12:39:27 +00:00
ad 0664a0459b Start detangling lock.h from intr.h. This is likely to cause short term 
breakage, but the mess of dependencies has been regularly breaking the
build recently anyhow.

ad ea3f10f7e0 Merge more changes from vmlocking2, mainly: 
- Locking improvements.
- Use pool_cache for more items.
 2007-12-26 16:01:34 +00:00
ad 461cd942ea Merge changes from vmlocking2 branch. 2007-12-08 15:00:13 +00:00
ad b470ab628d Use membar_*(). 2007-11-30 23:05:43 +00:00
yamt 354863d6e5 lockdebug_mem_check: turn a redundant check into a panic. 2007-11-26 08:16:49 +00:00
yamt 33e66db218 fix lockdebug_mem_check. 2007-11-22 10:47:37 +00:00
yamt 671754cc2e lockdebug_alloc: detect double initialization explicitly. 2007-11-21 11:33:11 +00:00
yamt 51e523b832 re-enable lockdebug_mem_check. ad@ said disabling it was a mistake 
in the first place.
the implementation has been changed to use rb-tree rather than hash
so that it can check regions larger than page size as well.
 2007-11-21 10:25:51 +00:00
yamt 87fcbb0fe8 remove #if 0'ed code. 2007-11-21 10:21:40 +00:00
yamt 38d5e34116 make kmutex_t and krwlock_t smaller by killing lock id. 
ok'ed by Andrew Doran.

matt 2cab8950e4 Don't static init simplelock (back out those changes). 2007-11-12 06:14:57 +00:00
matt 90ef495f4d use __SIMPLELOCK_UNLOCKED, not SIMPLELOCK_INITIALIZER 2007-11-12 06:07:43 +00:00
matt 11910619f7 Change some initialization of static queues to compile time. 
(xxx_INIT to xxx_HEAD_INITIALIZER).  Drop code which inits
non-auto (global or static) variables to 0 since that's
already implied by being non-auto.  Init some static/global
cpu_simple_locks at compile time.

ad d831186d55 Merge scheduler changes from the vmlocking branch. All discussed on 
tech-kern:

- Invert priority space so that zero is the lowest priority. Rearrange
  number and type of priority levels into bands. Add new bands like
  'kernel real time'.
- Ignore the priority level passed to tsleep. Compute priority for
  sleep dynamically.
- For SCHED_4BSD, make priority adjustment per-LWP, not per-process.

ad dde5d75e78 Fix spelling. 2007-10-27 01:23:25 +00:00
ad 11dc639958 Merge from vmlocking: 
- G/C spinlockmgr() and simple_lock debugging.
- Always include the kernel_lock functions, for LKMs.
- Slightly improved subr_lockdebug code.
- Keep sizeof(struct lock) the same if LOCKDEBUG.

yamt 6bcb315f7d lockdebug_abort: s/int/u_int/ for lock id as the rest of code. 2007-05-02 14:07:02 +00:00
ad 64e54fbb70 lockdebug: 
- Initialize on the first allocation.
- Handle overflow better. PR kern/35723.

thorpej 4f3d5a9cc0 TRUE -> true, FALSE -> false 2007-02-22 06:34:42 +00:00
thorpej dd962f8680 Pick up some additional files that were missed before due to conflicts 
with newlock2 merge:

Replace the Mach-derived boolean_t type with the C99 bool type.  A
future commit will replace use of TRUE and FALSE with true and false.
