| Revision | | Date | Author | Comments |
| 1.9 |
| 27-Feb-2003 |
fvdl | Adapt for move to x86/include.
|
| 1.8 |
| 26-Feb-2003 |
fvdl | Redirect some includes to x86/foo.h
|
| 1.7 |
| 30-Jan-2003 |
thorpej | Test _KERNEL_OPT before including opt_*.h files.
|
| 1.6 |
| 01-Oct-2002 |
fvdl | Merge Bill Sommerfeld's i386 MP branch. This code has some known
caveats, but works quite well in a lot of MP cases, and all
UP cases that I have tested. Parts of this will hopefully be
reworked in the not-too-distant future.

| 30-Apr-2001 |
lukem | branches: 1.5.2; 1.5.10;
remove some lint, including ansifying some inlines

thorpej | branches: 1.4.6; 1.4.8;
Let each platform typedef the new __cpu_simple_lock_t, which should
be the most efficient type used for the atomic operations in the
simplelock structure, and should also be __volatile.
|
| 1.3 |
| 29-Apr-2000 |
thorpej | Implement __cpu_simple_{,un}lock{,try}(), modeled after the Alpha
implementation.
|
| 1.2 |
| 29-Apr-2000 |
thorpej | Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.
These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

| 1.1 |
| 20-Feb-2000 |
sommerfeld | branches: 1.1.2;
file lock.h was initially added on branch sommerfeld_i386mp_1.
|
| 1.1.2.7 |
| 05-May-2002 |
sommerfeld | Make C++-safe
|
| 1.1.2.6 |
| 29-Dec-2001 |
sommerfeld | Add barriers, just in case
|
| 1.1.2.5 |
| 30-Apr-2001 |
sommerfeld | Catch up on some files missed the last time 'round
|
| 1.1.2.4 |
| 07-Jan-2001 |
sommerfeld | For the sake of my sanity, make this match the code in lock_machdep.c
a bit more closely.
|
| 1.1.2.3 |
| 31-Aug-2000 |
sommerfeld | Protect include of opt_lockdebug.h
|
| 1.1.2.2 |
| 03-May-2000 |
sommerfeld | Only do cpu_simple locks out-of-line if LOCKDEBUG is defined
|
| 1.1.2.1 |
| 20-Feb-2000 |
sommerfeld | Declarations of of cpu_simple_*lock* functions.
(currently not inlined, for debuggability)
|
| 1.4.8.2 |
| 18-Oct-2002 |
nathanw | Catch up to -current.
|
| 1.4.8.1 |
| 21-Jun-2001 |
nathanw | Catch up to -current.
|
| 1.4.6.2 |
| 20-Nov-2000 |
bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
|
| 1.4.6.1 |
| 02-May-2000 |
bouyer | file lock.h was added on branch thorpej_scsipi on 2000-11-20 20:09:29 +0000
|
| 1.5.10.3 |
| 20-Mar-2002 |
thorpej | * Add a memory clobber to the atomic operations in the lock-acquire
path, so that the compiler will treat them as a memory access barrier.
* Spin with a normal memory load until the lock is released and then
retry the compare-and-swap in __cpu_simple_lock().
|
| 1.5.10.2 |
| 20-Mar-2002 |
thorpej | Use the new P4 "pause" insn in the body of the __cpu_simple_lock()
loop.
|
| 1.5.10.1 |
| 19-Mar-2002 |
thorpej | Change __cpu_simple_lock_t to a single byte.
|
| 1.5.2.1 |
| 10-Oct-2002 |
jdolecek | sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work
