riastradh | vax: __cpu_simple_lock audit.
Fix missing "memory" asm clobber so the compiler can't reorder memory
access around __cpu_simple_lock/lock_try/unlock.

riastradh | __cpu_simple_lock(9): Omit needless barriers in init.
It is, and always has been, the caller's responsibility to ensure the
lock is initialized before it can be used -- otherwise the memory
could hold garbage; it is nonsensical to even attempt locking
operations on it before initialization.
So there's no need to issue explicit barriers here. The barrier
seems to have been introduced in sys/arch/alpha/alpha/lock_machdep.c
rev. 1.1 (since moved to inline asm in alpha/include/lock.h) and then
copied & pasted into several other architectures.

more const.

matt | branches: 1.28.4; 1.28.12;
A number of performance changes:
Change internal register SSP to contain curlwp insread curcpu(). This
shrinks the GENERIC by 2KB.
Add rwlock stubs (rw_enter, rw_exit, rw_tryenter).
Simplify simple lock code for uniprocessors.
Do SPL raise/lower in cpu_handle_ipi instead of simple_locks.

garbled | branches: 1.27.12; 1.27.16;
Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

cpu_simple_lock() calls are emitted in the UP case if DEBUG || DIAGNOSTIC.
This should probably be fixed somewhere else, but currently just include
it here. Fixes PR#35866 from Henry R. Bent.
|
| 1.24 |
| 26-Feb-2007 |
christos | - use __inline like the other ports do.
- use __ in parameter names
- provide separate prototype lines.

Partially adapt the VAX port to the newlock2 changes. These are untested
but they do at least compile.

christos | merge ktrace-lwp.
|

| 20-Jul-2005 |
he | Fixes to make GENERIC.MP build again. Several changes:
o Rename global variable "tramp" to "vax_mp_tramp" to avoid warning
with -Wshadow when compiling the signal code.
o Rename a macro-local variable _s to __s in __cpu_simple_lock()
to avoid -Wshadow warning when MALLOC() is used (also declares _s).
o Follow up -Wcast-qual by making a number of function arguments const char*
where string literals are used.

Hm, let ipfresend also compile; move <machine/intr.h> include
in under the _KERNEL_OPT define.
|
| 1.15 |
| 19-May-2004 |
he | Since we are using the spl() functions here, also include <machine/intr.h>.
|
| 1.14 |
| 26-Sep-2003 |
nathanw | Move __cpu_simple_lock_t and __SIMPLELOCK_{UN,}LOCKED to machine/types.h
so that they can be used in a namespace-friendly way.

#ifdef _KERNEL_OPT police; identd defines _KERNEL before some includes.
|

martin | Make sure to include opt_foo.h if a defflag option FOO is used.
|
| 1.11 |
| 25-Feb-2003 |
matt | This file has a _KERNEL dependency on <machine/cpu.h>. So include it.
[GENERIC.MP builds again.]
|
| 1.10 |
| 10-Oct-2002 |
thorpej | Add missing register prefixes.
|
| 1.9 |
| 12-Sep-2002 |
matt | Add non-_KERNEL variants so regress/sys/kern/lock will compile.
|
| 1.8 |
| 04-Jun-2001 |
ragge | branches: 1.8.2; 1.8.8;
Add rudimentary multiprocessor support for DDB.
|
| 1.7 |
| 04-Jun-2001 |
ragge | Check for console printf's in spinlocks, per discussion on tech-smp.
|
| 1.6 |
| 03-Jun-2001 |
ragge | Implement spinlocks as subroutines instead of inlines.
Add SPINLOCK_SPIN_HOOK; the VAX has low-priority IPIs like Alpha.

matt | branches: 1.5.2; 1.5.4;
GCC 2.96 wants the = constraint first. Also change to be a bit more
efficient. Instead of using indirect register access, change the
constraint to memory and use the value directly. This allow PC-rel
access among other things.
|
| 1.4 |
| 02-May-2000 |
thorpej | 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 |
| 01-May-2000 |
ragge | #define __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED.
|
| 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 |
| 19-Mar-2000 |
ragge | First cut of multiprocessor support for vax. Still much to do before
other CPUs than the master can spin up.

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.
