riastradh | lockstat(4): Membar audit.
- Serialize updates to lockstat_enabled, lockstat_dev_enabled, and
lockstat_dtrace_enabled with a new __cpu_simple_lock.
- Use xc_barrier to obviate any need for additional membars in
lockstat_event.
- Use atomic_load/store_* for access that might not be serialized by
lockstat_lock or lockstat_enabled_lock.

christos | Fix non-cpu counter build.
|
| 1.13 |
| 09-Mar-2015 |
christos | Introduce a new flag LB_DTRACE for dtrace lockstat events.
Split lockstat_enabled into two parts, one controlled by dtrace called
"lockstat_dtrace_enabled" and one by the lockstat device called
"lockstat_dev_enabled". Create a macro that needs to be called when either
of them changes LOCKSTAT_ENABLED_UPDATE().

| 1.10 |
| 20-Jan-2009 |
yamt | branches: 1.10.24; 1.10.42;
bump lockstat interface version for timespec.
|
| 1.9 |
| 28-Apr-2008 |
martin | branches: 1.9.8;
Remove clause 3 and 4 from TNF licenses
|
| 1.8 |
| 28-Apr-2008 |
ad | Add MI code to support in-kernel preemption. Preemption is deferred by
one of the following:
- Holding kernel_lock (indicating that the code is not MT safe).
- Bracketing critical sections with kpreempt_disable/kpreempt_enable.
- Holding the interrupt priority level above IPL_NONE.
Statistics on kernel preemption are reported via event counters, and
where preemption is deferred for some reason, it's also reported via
lockstat. The LWP priority at which preemption is triggered is tuneable
via sysctl.
|
| 1.7 |
| 26-Jan-2008 |
ad | branches: 1.7.6; 1.7.8; 1.7.10;
lockstat: no longer track lockmgr() events.
|
| 1.6 |
| 04-Jan-2008 |
ad | 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.
|
| 1.5 |
| 14-Jul-2007 |
ad | branches: 1.5.8; 1.5.14; 1.5.20;
- Increase default number of trace buffers to 10000.
- New options:
-f Trace only by calling functions.
-m Merge call sites within unique functions.
-M Merge lock addresses within unique objects.

| 1.4 |
| 09-Feb-2007 |
ad | branches: 1.4.6;
Merge newlock2 to head.
|
| 1.3 |
| 29-Jan-2007 |
hubertf | Remove more duplicate headers.
Patch by Slava Semushin <slava.semushin@gmail.com>
Again, this was tested by comparing obj files from a pristine and a patched
source tree against an i386/ALL kernel, and also for src/sbin/fsck_ffs,
src/sbin/fsdb and src/usr.sbin/makefs. Only changes in assert() line numbers
were detected in 'objdump -d' output.

could spin while resorting lists.
