m68k: __cpu_simple_unlock audit.

- Use `cc' clobbers in asm volatile because they touch the condition
  codes.

- Use `memory' clobbers in asm volatile so the compiler doesn't move
  up loads and stores in the critical section at _other_ addresses
  than the lock so they happen before __cpu_simple_lock or
  __cpu_simple_lock_try.

- Not sure if we have any (or if there even are any?) multicore m68k
  systems out there, but __cpu_simple_unlock needs __insn_barrier
  either way so the compiler doesn't delay loads and stores prior to
  __cpu_simple_unlock so they happen after it.

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.

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.

FILE REMOVED

file lock.h was added on branch thorpej_scsipi on 2000-11-20 20:11:39 +0000

On the m68k, the most efficient type for __cpu_simple_lock_t is
an unsigned char, since that is what the `tas' instruction uses.

While I'm here, implement the __cpu_simple_lock family of routines.
Why?  One, because they're easy.  Two, so Steve can get master/slave
MVME systems talking across the backplane.  :-)

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.

Revision 1.1 / (download) - annotate - [select for diffs], Sat Apr 29 03:31:50 2000 UTC (22 years, 9 months ago) by thorpej
Branch: MAIN

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>.
